Description
Technical field
The present invention relates to Parts of Compressor technical fields, more particularly, to a kind of valve group portion of low-loss compressor
Part and compressor.
Background technique
Reciprocating piston refrigeration compressor passes through the operating of motor at work, and crank link mechanism is driven to push piston
It moves back and forth, the suction and discharge valve block in valve group is intermittently opened under piston effect, closed, constantly sucking and discharge refrigeration
Agent, to realize refrigeration.In the various factors for influencing compressor efficiency, volumetric efficiency is very important one.And certainly
In the factor for determining compressor volumetric efficiency, clearance volume, i.e. piston reach after top dead center, are formed between pistons end and valve plate
Residual volume be very important.Clearance volume is smaller, and residual gas gas volume shared by reflation in air-breathing is got over
Small, volumetric efficiency is higher.In the compressor using monoblock type absorption valve plate structure, the tongue part of suction valve chip and support
Interregional gap is a part for constituting clearance volume.In order to reduce the clearance volume of the part as much as possible, often should
Gap is sized to very little, however this design will lead to the material cost of suction valve chip and difficulty of processing increases.
Currently, structure of the existing valve group using concave valve plate or thick steel plate, so that spill valve group processing technology is poor,
Its slip is higher after valve group assembly；Clearance volume increasing, the performance decline of compressor will lead to using thick steel plate simultaneously.
In Chinese patent application CN201020271475.1, a kind of freezer compressor valve group is provided, it is by valve plate pad
Piece, air-intake valve plate, steel part valve plate, exhaust valve plate, gland shim and cylinder cover composition.Valve plate gasket, air-intake valve plate, steel part valve
Plate, exhaust valve plate, gland shim and cylinder cover are sequentially overlapped placement from bottom to up.Production has moving valve on inlet and outlet valve block
Piece, and be monolithic construction.The steel part valve plate of the freezer compressor valve group is using sheet metal compacting, grinding molding, processing technology
Simply, clearance volume is smaller, and the refrigerating capacity of compressor is improved.Exhaust valve plate and movable valve plate use full slice system structure, with
Steel part valve plate can be very good to be bonded, and have preferable assembly process process and lower valve group slip.Solves existing valve
For group using the structure of concave valve plate or thick steel plate, processing technology is poor, and slip is higher after valve group assembly, while will lead to remaining
The problem of gap volume increases, and compressor performance declines.
Although the patent reduces the thickness of valve plate to a certain extent, thus to achieve the purpose that reduce clearance volume,
But in actual use, since valve plate thickness reduces, so that its remitted its fury, causes exhaust valve plate or suction valve chip doing
It will drive valve plate in reciprocatory movement to be deformed, to influence its using effect, and since valve plate needs to limit lift
Device is defined, and it is too small that this results in valve plate thickness to be not easy, and the reduction of valve plate thickness is limited to.
Therefore, for the above technical issues, it is badly in need of inventing a kind of structure to solve above-mentioned technical problem.
