General Knowledge on “4-Way Reversing Valve”

Four-way reversing valve principle

By changing the flow channel of the refrigerant, changing the direction of the refrigerant, the functions of the indoor and outdoor units of the air conditioning system in winter and summer are changed: in summer, the refrigerant liquid evaporates and absorbs heat into the gas in the indoor unit (the evaporator at this time) The outdoor unit (condenser at this time) releases heat for indoor cooling; in the winter, the refrigerant liquid evaporates in the outdoor unit (in this case, the evaporator) to absorb external heat, and in the indoor unit (in this case, the condenser) Exothermic for indoor heating.

Use

Generally can be used in ordinary cooling and heating air-conditioning systems, cooling in summer and heating in winter.

Metal Tube Fabrication

Die-casting fabrication in China–Customize/manufacture Metal Die-casting products

Die casting fabrication means metal casting process that is characterized by forcing molten metal with strong pressure into a mould cavity which is created using two hardened tool steel dies. Most of die castings are made from zinc, copper, aluminium, magnesium, lead, pewter and tin based alloys. Depending on the type of metal being cast, a hot- or cold-chamber machine is used.

MetalHelper provide die-casting fabrication in China.We are China manufacturers of aluminum castings, magnesium die castings, bronze castings, copper castings,stailess steel casting and zinc castings.

MetalHelper’s die casting foundry in China is able to manufacture low pressure and high pressure die castings specializing in aluminum and magnesium die castings. Low pressure die casting is commonly used for non-critical parts, whereas high pressure castings are used for tight tolerance detailed geometry parts. High pressure die castings can maintain tighter tolerances and more detail than low pressure die casting because the extra pressure pushes the metal into more detailed features in the mold. Aluminum and magnesium die casting in China is very popular due to the high quality and competitive prices.

Magnesium die castings is popular in the electronics and automotive industries because of their light weight, and strong mechanical properties.

Magnesium die castings are perfect choie where weight savings are the primary goal as they are almost as light as plastic. Magnesium die castings are superior over plastics due to improved rigidity, inherent EMI shielding, heat dissipation, durability and the ability to fully recycle. Magnesium die castings are able to provide more detailed and tighter tolerance parts than aluminum die castings.

Our factory in China also offers die castings in zinc, bronze, copper and aluminum alloy castings, with plating, finished machining, polishing and other secondary operations.

Our high pressure die castings have excellent surface finishes that are consistent dimensionally with precision features and minimum draft. We are one stop sourcing for engineered and aluminum die castings, magnesium die castings, zinc castings, brass castings, and copper castings. Die casting alloys are non-ferrous and there are a large number available with a wide range of physical and mechanical properties to cover almost every application a designer might need.

Our die cast parts are made in China to the highest standards and used for many industries including electronics, pumps and valves, propane gas, automotive, aerospace, business and office, construction and medical. Be sure to visit our other metal manufacturing pages for more information on other manufacturing techniques. We offer state of the art die casting production capabilities in China and complete secondary finishing capabilities.

General knowledge on “Metal Tube” for fabrication

The metal tube which can be fabricate include Carbnon steel tube,Stainless steel tube,Aluminium tube,Copper Tube,and other metallic tube. In this charter,mainly introduce general knowledge on carbon steel tube.

Generally, the cabon steel tube to be fabricated in the field of industry can be devided welded tube and seamless tube.

Welded tube/pipe refers to a steel strip or plate bending round, square and other shapes and then welded together,the surface has a jointed seal. Welded tube is made from steel sheet or belt steel. Bydifferent welding processes,it can be divided into the arc welding tube/pipe, high-frequency or low frequency electric resistance welded tube, gas tube, stove tube, Bundy tube ,and so on.According to the shape of welding,can be divided to
Longitudinal tube and spiral welded tube .Generally,they are made with ordinary carbon steel Q235, Q235F, Q195 and ordinary low-alloy structural steel 16Mn welded, used for a low pressure fluid delivery.

Seamless tube/pipe is a pipe that with hollow section, no seam on the around surface.
It is usually made with carbon steel 10,20,30,35,45, such as high-quality carbon steel 16Mn, 5MnV low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2,40MnB and other structural steel hot-rolled or cold-rolled steel. 10,20 and other low-carbon steel seamless pipe is mainly used for fluid pipes. Seamless 45,40Cr etc. made of carbon steel used to manufacture mechanical parts, such as cars, tractors and the force components. General seamless pipe to ensure the strength and flattening test. Hot-rolled steel hot-rolled state or heat treatment delivery; cold to hot to heat treatment delivery. Low-pressure boiler seamless pipe: for the manufacture of a variety of low and medium pressure boiler superheated steam pipes, boiling water pipes, water wall tubes and superheated steam locomotive boiler tubes, opium pipe, small pipe and brick arch tubes.
(Dial) with high-quality carbon structural steel seamless hot-rolled or cold-rolled. Steel 10,20 is mainly used, in addition to chemical composition and mechanical properties of outside pressure to do testing, crimping, flaring, flattening and other tests. State of delivery hot rolled, cold-rolled (allocated) to heat treatment delivery.

According to the different production methods,the seamless tube can be divided into hot-rolled tubes, cold-rolled, cold drawn tubes, squeeze tubes:
1.1, hot-rolled seamless tube generally automatic pipe mill production. Solid tube defects after inspection and clear surface, cut into desired length, end to end in the perforated tube centering surface, and then sent to the furnace heating, perforation on the puncher. While continuing to rotate and move forward in the perforation, in the role of head of the roll and, gradually forming a cavity inside the tube, called capillary. Continue rolling and then sent to the automatic rolling machine. Finally, after all the whole entire thickness of both, the sizing mill sizing, to specifications. The use of continuous production of hot-rolled seamless steel pipe mill is more advanced methods.
1.2 putting up get smaller size and better quality seamless, must be cold-rolled, cold drawn or a combination of the two. Cold rolled usually the two-roll mill, steel pipe in the hole section becomes circular hole slot and does not move the cone head composed of rolling. Drawing is usually performed on the 0.5 ~ 100T single chain or double chain drawing machine.
1.3, the upcoming heating extrusion good squeeze tube placed in a sealed cylinder, piercing rod and rod movement squeeze together to make the extrusion die extrusion from the smaller hole. This method can produce smaller diameter steel pipe.

According to the different materials,the metal tube for fabrication Carbon steel tube,stainless steel tube,copper or brass tube,aluminium tube,they are including hollow tubes/pipes and solid bars.

What is the difference between tube & pipe material? Tube fabrication material is straight forward. Tube is usually used for store fixtures or structures where you want the measurement to be on the outside. Tube is defined and measured by the OD or outside diameter. The strength of the tube or pipe is defined by the wall thickness. Tube bending and forming is most consistent than pipe because the OD tolerance is more consistent and that is how a bending is set-up, to the outside dimensions of the tube or pipe. Pipe manufacturers make sure that the ID is the most consistent feature of pipe because fliuds or other objects are normally inside.

 General Knowledge on “Sheet Metal Fabrication”

Sheet Metal Fabrication is based on the difference sheetmetal structure, process may vary, but the total does not exceed the following points.

1, Sheet Metal Fabrication–cutting: cutting a variety of ways, there are several ways
①. Scissors: Scissors cut using a simple strip materials and parts, it is primarily for blanking forming mold preparation and processing, low cost, accuracy of less than 0.2, but can only process nonporous no chamfered strip or block material.
②. Punch: Punch is the use of one or more steps in the flat pieces of sheet metal stamping parts will commence after forming various shapes of materials and parts, the advantage of cost and shorter, high efficiency, high precision, low cost, suitable for mass production, but to design the mold.
③. NC CNC cutting, the first to be prepared when cutting CNC machining NC program, use programming software, an expanded view of the preparation will be drawn into the NC machine tools pull a few recognizable program, let knife punching each step on the plate according to these programs Frame shape flat pieces, but its structure by the tool structure actions, low cost, precision 0.15.
④. Under the laser material, the use of laser-cut way, in large flat shape of the structure will be cut out of their flat, with NC laser cutting, like the need to write programs that can be flat pieces of a variety of complex shapes, high cost, accuracy to 0.1 .
⑤. Sawing: mainly used under aluminum, square tube, showing the pipe, rod material and the like, low cost, low accuracy.
2. Sheet Metal Fabrication–Fitter: sink hole, tapping, reaming, drilling
Countersink angle is generally 120 ℃, for pop rivets, 90 ℃ for countersunk screws, tapping Inch Bottom.
3.Sheet Metal Fabrication– Flanging: also known as pumping hole, turn the hole is on a smaller base hole pumped into a slightly larger hole, and then tapping, mainly with relatively thin thickness of sheet metal processing, increase its strength and number of threads avoid slip teeth, generally used for relatively thin thickness, its shallow hole flanging normal week, unchanged thickness, allowing a thinner thickness of 30-40% higher than the normal height and large available flanging 40- 60% of the height, with extruded thin 50%, may be the largest flange height, when the plate thickness is large, such as 2.0, 2.5, and above the plate thickness, can be directly tapping.
4. Sheet Metal Fabrication–Punch: The use of mold forming manufacturing processes, there are punching, Cutaway, blanking, punching convex hull (bump), red tear, pumping holes, forming presses and other processing methods are generally processed, the processing need to have appropriate mold to complete the operation, such as punching blanking die, the convex hull mold, tearing mode, pumping hole mold, molding, etc., the main attention to the location of the operation, direction.
5. Sheet Metal Fabrication–Clinching: riveted on this company, there are rivet nuts, screws, captive, etc., which are riveted by a hydraulic press machine, or to complete the operation, which was riveted to the sheet metal parts, as well as up riveting way, the need to pay attention to direction.
6. Sheet Metal Fabrication–Bending and Deforming; bending the plate member is a 2D, 3D folded parts. Its processing requires folding bed and the corresponding bending mold is completed, it also has some bending sequence, the principle is under the knife does not interfere in the first fold, will produce interference after the break.
7.Sheet Metal Fabrication– Welding:
① classification:  fusion welding: welding, CO2 welding, gas welding, manual welding;pressure welding: welding, butt welding, soldering hit;Brazing: electric welding chromium, copper
② welding:  CO2 gas shielded arc welding;TIG welding; spot welding;robot welding
Selection of welding methods are based on actual requirements and the material may be, in general, CO2 gas shielded arc welding classes for welding iron daub; welding for stainless steel, the aluminum type welding, robotic welding, can save time, improve efficiency and welding quality, reduce the intensity.
③ welding symbols: Δ fillet, Д, I type welding, V-weld, unilateral V-weld (V) with a blunt edge V-weld (V), spot welding (O), plug welding or groove weld (Π) curling welding (χ), with a blunt edge unilateral V-weld (V), U type of ribbon blunt with blunt J-welding, welding back, every weld
④ arrow lines and connectors
⑤ welding deletion and its preventive measures fail
Spot welding: strong enough to play bump imposed welding area
CO2 welding: high productivity, low energy consumption, low cost, strong anti-rust capability
TIG: melting depth, welding speed is slow, inefficient, high production costs, with the clip tungsten defects, but with the advantage of a better quality of welding can weld metals, such as aluminum, copper and magnesium.
⑥ welding deformation reasons: lack of preparation prior to welding, an additional clamp
Adverse improve the process of welding jig
Welding sequence bad
⑦ welding deformation effect Dharma:
Flame effect Dhamma
Vibration Method
Hammer

Commen steel sheet for Sheet Metal Fabrication:

1. Galvanized steel SPCC
SECC substrates for general cold rolled steel coils, galvanized in a continuous production line after degreasing, pickling, electroplating and various post-treatment process, it becomes galvanized products. SECC only has the mechanical properties of cold-rolled steel sheet and approximate general workability, and has excellent corrosion resistance and decorative appearance. Has great competitive and substitutes on electronics, home appliances and furniture markets. For example, the widespread use of computer chassis is SPCC.
2. Ordinary SPCC cold rolled sheet
SPCC refers to the continuous cold rolling mill rolling ingot through a desired thickness steel roll or sheet material. SPCC surface without any protection, exposure to easily oxidized in air, oxidation speed, especially in humid environments, appear dark red rust, in the use of the surface to be painted, plated, or other protection.
⒊ hot-dip galvanized steel SGCC
Hot-dip galvanized steel coil refers to semi-finished products after the hot pickling or cold, after cleaning, annealing temperature of about 460 ° C immersed in molten zinc bath, leaving the steel coated with zinc layer, and then quenched leveling and chemical treatment is made. SGCC material material harder than the SECC, ductility (avoid deep drawing design), zinc layer is thick, welded poor.
4. Stainless steel SUS304
One of the most widely used stainless steel, because it contains Ni (nickel) so than containing Cr (chromium) steel richer corrosion resistance, heat resistance, and has a very good mechanical properties, non-hardening heat treatment, there is no flexibility.
5. Stainless steel SUS301
(Cr) Cr content lower than the SUS304, corrosion resistance is poor, but after punching in the cold to get a good tension and hardness, good elasticity, and more for shrapnel springs and anti-EMI.

General Knowledge on “Titanium tube”

Titanium-tubeTitanium tube is light weight, high strength, excellent mechanical properties. It is widely used in heat exchange equipment, such as a tube heat exchangers, plate heat exchanger tube, snake tube heat exchangers, condensers, evaporators and transportation pipelines.
Titanium is a new type of metal, and the performance of the carbon-containing titanium impurity content of nitrogen, hydrogen, oxygen and so on, the most pure titanium iodide impurities is not more than 0.1%, but its low strength, high ductility. 99.5% for the performance of industrial pure titanium: density ρ = 4.5g / cm3, a melting point of 1725 ℃, thermal conductivity λ = 15.24W / (mK), tensile strength σb = 539MPa, elongation δ = 25%, necking rate ψ = 25%, the elastic modulus E = 1.078 × 105MPa, the hardness HB195. Detailed performance titanium tube as follows:
(1) high specific strength
The density of titanium is generally about 4.5g / cm3, only 60% of steel, titanium’s strength was close to the strength of ordinary steel, some high-strength titanium alloy structural strength than a lot of steel. Therefore, the ratio of titanium alloy strength (strength / density) is much larger than other metallic structural materials, see Table 7-1, can be made out of high unit strength, rigidity, lightweight parts and components. Currently aircraft engine components, skeleton, skin, so the use of titanium fasteners and landing gear.
(2) high thermal strength
Temperature hundreds of degrees higher than aluminum, at moderate temperatures can still maintain the desired strength, long-term work at a temperature of 450 ~ 500 ℃ of these two types of titanium in the range of 150 ℃ ~ 500 ℃ still very high strength, and aluminum at 150 ℃ decreased significantly when compared strength. Titanium’s operating temperature up to 500 ℃, aluminum is below 200 ℃.
(3) corrosion resistance
Titanium work in humid atmosphere and seawater, which is far superior corrosion resistance of stainless steel; for pitting, etching, stress corrosion resistance is particularly strong; alkali, chloride, chlorine organic materials, nitric acid, sulfuric acid and so it has excellent corrosion resistance. However, the corrosion resistance of titanium with a reduction of oxygen and chromium salts medium is poor. Commonly used in seafood brackish water cooling, heating heat exchanger (which can be included on titanium electric heating rods in titanium evaporator).
(4) good low temperature performance
Titanium alloys at low and ultra-low temperature, retain their mechanical properties. Low temperature performance, low interstitial elements of titanium, such as TA7, at -253 ℃ can maintain a certain degree of plasticity. Thus, titanium is also an important low temperature structural materials.
(5) The chemical activity of large
Chemical activity of titanium is large, a strong chemical reaction with atmospheric O, N, H, CO, CO2, water vapor, ammonia and the like. Carbon content greater than 0.2%, it will form a hard TiC in titanium alloys; the temperature is high, and the role of N will form TiN hard surface; above 600 ℃, high hardness of hardened layer of titanium absorbs oxygen is formed ; hydrogen content increased, brittle layer will form. Absorbing gas generated brittle surface layer depth of up to 0.1 ~ 0.15 mm, the degree of hardening of 20% to 30%. Titanium is also large chemical affinity, easy and sticking friction surface.
(6) thermal conductivity, small elastic modulus
Thermal conductivity of titanium λ = 15.24W / (mK) approximately 1/4 of nickel, iron 1/5, 1/14 of aluminum, while the thermal conductivity of various titanium decreased by 50% than the thermal conductivity of titanium. The elastic modulus of about 1/2 of titanium alloy steel, so the poor rigidity, deformation, not making slender rod and thin-walled parts, cutting the amount of the machined surface rebound large, about 2 to 3 stainless steel times, causing intense friction of tool flank, adhesion, adhesive wear.
