Detailed description of the invention
Below embodiments of the invention being elaborated, the present embodiment is carried out under premised on technical solution of the present invention, gives detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
A kind of bimetallic Snifter valve block of refrigerator compressor, including valve body 1 and tongue 2, it is characterised in that: tongue 2 and valve body 1 are made by the material of unlike material, and valve body 1 is provided with spring hole 4, tongue 2 is arranged in spring hole 4, and the afterbody of yellowish fur on the tongue and valve body 1 weld together in the inside edge place in spring hole 4.Because the design of integral type, together with tongue 2 is designed with valve body 1, the stress concentration phenomenon that tongue 2 end section exists requires over light decorations process and solves, but abrasive material size is often bigger, it is necessary to the decorated processing through the plenty of time can obtain qualified product.By by tongue 2 from the design separated valve block, it is possible to easily and fast the section of tongue 2 end is carried out light decorations, saves the substantial amounts of time, make production efficiency be greatly promoted.Simultaneously because valve body 1 with tongue 2 owing to residing working environment performance requirement to material different from the function of required performance there is also difference, select and can meet the two material required simultaneously and waste time and energy, and effect is often barely satisfactory.This problem is perfectly solved by the scheme welded together again after using different manufacture of materials.
The tensile strength of the material that valve block uses, hardness, fatigue strength and corrosion resistance are better than the material that valve body 1 uses.Tongue 2 part of suction valve chip can use anti-fatigue performance preferred materials stamping-out, and the relatively low common valve steels of the valve body 1 part available rates that connects tongue 2 replaces, and so can also save the consumption of more expensive high-performance valve steels material, reduce valve block cost.
Valve block uses 20C material to make, and valve body 1 uses 7C27Mo2 or Hiflex material to make.Valve block uses 20C material to make, valve body 1 uses to have and makes compared with high-mechanical property and expensive 7C27Mo2 or Hiflex material, what the effect of valve body 1 was prayed is only fixing effect, its mechanical property requirements is very low, but tongue 2 is operationally doing vibration up and down at a high speed, require that its material has very strong mechanical performance, the processing of tongue 2 only needs to expend a small amount of material, and expend the valve body 1 high performance material without use costliness of more material, this problem is perfectly solved by split type design, it is greatly saved production cost.
Tongue 2 and what valve body 1 obtained each through stamping procedure, tongue 2 also through polishing, then welds with valve body 1 after stamped again.Punching production is that material is torn the product obtaining needing, and so can there is small burr and the place of stress concentration at the edge of tongue 2, can be polished by the burr that these are tiny by polishing, make stress be released simultaneously.On the suction valve chip of common integral type, a gap only very thin between valve body 1 and conjunction tongue 2, when valve block is polished, abrasive material cannot pass the end to tongue 2, the gap through row polishing at all.
Forming tongue gap 3 between tongue 2 outline and inner edge, spring hole 4, the width in tongue gap 3 is less than 0.2 millimeter.The valve block of common integral type, restriction due to punching operation, it is difficult on material, process narrower slit, the single capacity of freezer compressor is only small, excessive tongue gap 3 can cause that the cold-producing medium of residual is too much in tongue gap 3, affect exhaust coefficient so that efficiency less than big lifting.It is less that design during separation makes tongue gap 3 to accomplish, exhaust coefficient is bigger, improves the refrigerating efficiency of compressor.The discharge capacity of freezer compressor is generally smaller, so its clearance volume should be reduced as far as possible to improve its capacity, thus improving the refrigerating efficiency of compressor, such freezer compressor tongue gap 3 also can retain more cold-producing medium and fail to be discharged in refrigeration system when compressor operating, directly influence the refrigerating efficiency of freezer compressor, good refrigerating efficiency can be obtained by reducing tongue gap 3.
Tongue 2 two sides of tail arranges locating slot 21, tongue 2 afterbody bottom side setting direction groove 22, and the position matched with locating slot 21 on inner edge, spring hole 4 arranges guide pile 41, the position setting direction stake 42 matched with direction groove 22 on inner edge, spring hole 4.By the design of locating slot 21 and direction groove 22 and matched guide pile 41 and alignment stake 42, it is accurately positioned the tongue 2 position in spring hole 4, facilitates follow-up welding operation, make the quality of product be guaranteed.
These are only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
