Abstract
The invention relates to the field of refrigerator or freezer compressors and provides a high-efficiency valve block for the refrigerator or freezer compressor. The high-efficiency valve block comprises a valve plate and an exhaust valve block, wherein the exhaust valve block comprises a front part, a middle part and an end part; the front part is circular and covers a valve line of the valve plate; an elastic lug is arranged at the end part of the exhaust valve block; a lug moving space is arranged between the elastic lug and the exhaust valve block. The elastic lug is arranged on the exhaust valve block, so that the exhaust valve plate is conveniently fixed in the valve plate; in addition, the exhaust valve block is fixed by the elastic lug and the lug moving space, so the more tight assembly effect is realized, and the phenomenon that the exhaust valve block is broken and generates other fatigue loss and noises due to the fact that the stress of the exhaust valve block is changed caused by overlarge vertical displacement of the exhaust valve block in a valve block groove of the valve plate is avoided.
Description
Technical field
The present invention relates to freezer compressor field, more particularly to a kind of reliability height, the compression of the refrigerator of good airproof performance, refrigerator
Machine valve block.
Background technology
Valve plate on refrigerator compressor is one of critical component.Exhaust valve plate, aerofluxuss are installed on valve plate
Valve block by vent hole seal, when compressor cylinder base cylinder holes pressure is more than equipped with exhaust valve plate lateral pressure, beaten by exhaust valve plate
Open, cold-producing medium arrives refrigerant system condenser after valve plate steam vent after being compressed by pistons after two-stage noise elimination, because aerofluxuss
Valve block is per minute will to be opened, closed reduction at least more than 2920 times, and existing valve block is in installation process due to installing groove with valve plate
Category gap coordinates, and because of gap reason during valve block is installed, causes exhaust valve plate root dislocation occur, causes valve block front portion to be deposited
Affect air-tightness and to produce noise upper and lower displacement is excessive, and due to causing valve seat to bestow valve block reaction force acts point after dislocation
Change, easily cause stress after valve block dislocation and change, valve block becomes with valve plate air vent valve line air-tightness
Change, cause exhaust gas leakage, while valve block stress changes, cause the violent noise of valve block generation and reliability to reduce,
And there is rupture hidden danger, affect the work of compressor.
Valve block of the prior art adopts structure as illustrated in fig. 1 and 2, by end construction and valve plate as shown in Figure 1
On the assembling of valve block groove one end clearance-type, because gap assembling has dislocation hidden danger, cause valve block front portion to there is upper and lower displacement excessive
Affect air-tightness and produce noise.Therefore, solution valve block is easily broken off and valve block easily misplaces and causes sealing bad and noise
Problem is just particularly important.
The content of the invention
Facilitate durable freezer compressor valve plate it is an object of the invention to provide a kind of, shot by adding in valve block root
Property lug, for fixing valve block, and valve block is made using Hiflex steel, prevent valve block because misplace it is excessive cause valve block to rupture, solve
Valve block of having determined is easily broken off and valve block seals the excessive problem of bad and noise.
Preferably, a kind of efficient valve block of refrigerator compressor, the exhaust valve plate includes anterior, middle part and end, institute
It is circle to state anterior, is covered at the valve line of valve plate, and the end of the exhaust valve plate is provided with elastic lug, the elastic lug
Lug activity space is provided between exhaust valve plate.
Preferably, the exhaust valve plate width A is 3.35 ~ 3.50mm.
Preferably, the end afterbody middle of the exhaust valve plate is provided with opening, the opening and lug activity space phase
Connection.
Preferably, the lug activity space is arc-shaped through-hole.
Preferably, the radian of the lug activity space is consistent with the linear radian in the bottom of end.
Preferably, the lug activity space is crescent through hole.
Preferably, the exhaust valve plate material is Hiflex steel.
Preferably, the exhaust valve plate material is martensitic stain less steel 7C27Mo2.
Beneficial effects of the present invention：By arranging elastic lug on exhaust valve plate, because exhaust valve plate width A is than existing
Valve block size about 0.03mm ~ 0.11mm, easy to exhaust valve block is fixed in valve plate, and by elastic lug and lug activity
Exhaust valve plate is fixed with effect is more closely assembled in space, makes exhaust valve plate be unlikely to the upper and lower displacement in valve plate valve block groove
Greatly, the valve block stress change fatigue damage such as make exhaust valve plate fracture, Main Function is caused to be：（1）Exhaust valve plate position is consolidated
Uniform force after fixed, good airproof performance, noise is low；（2）Exhaust valve plate operationally has high temperature, high pressure, and with cold-producing medium, cold
In the environment of freezing machine oil, the reliability of valve block is greatly improved by the design of this structure and material, substantially reduces failure and broken
Situation about splitting occurs, and reduces valve block noise.
