Description
Technical field
The parts of freezer compressor are the utility model is related to, more particularly to a kind of double tongue freezer compressors of ultra high efficiency are inhaled
Air valve plate.
Background technology
It is well known that Snifter valve block of refrigerator compressor is the conveying for controlling refrigerant within the compressor, the unlatching of tongue
It is that constantly alternately valve block tongue is acted in the process of unlatching by alternate load, and alternate load pair with closing
The anti-fatigue performance influence of tongue is very big, and the sectional area of the state in cantilever, particularly cantilever is bigger when tongue is opened, tongue
The anti-fatigue performance of spring is poorer；The tongue majority of existing Snifter valve block of refrigerator compressor is overall structure, that is, air-breathing
The tongue of valve block and the body portion of connection tongue are an entirety, and the sectional area of single tongue cantilever part is larger, is handing over
Fatigue performance is poor under varying load；On the other hand, the tongue of overall suction valve chip is because the gap between valve body can not
It is too small, thus tongue time when light is adornd will be very long and be difficult to reach preferable section R angles and section, and processing cost
It is larger, light decorations the time also grow, to improve production efficiency it is also unfavorable, in addition in reed tongue open and close with valve plate poor sealing
And small leakage is caused, the refrigerating efficiency of compressor can be also affected；On the other hand, refrigeration compressor air suction valve block
Raw material China used can't produce, and be currently the valve steels from external import, price is costly.
The overall tongue of prior art will be divided into two by the utility model under conditions of by same alternate load
Part, the sectional area of such cantilever part just correspondingly reduce the endurance of now valve block tongue with the cantilever part of single tongue
Performance is just correspondingly good more；The injustice at R angles and section at another aspect tongue section rim is also that influence tongue is resistance to tired
One key factor of labor performance；Meanwhile monoblock type suction valve chip in the market is because it is small with the gap of valve body, therefore
When carrying out light decorations to it, difficulty is larger, and the light decorations time is oversize, also unfavorable to the cost of processing；The utility model be directed to
Upper technical problem, it is proposed that with double tongues and valve body carry out it is detachable combine installation, while in order to cost-effective, by tongue
Valve steels of the piece part with price costly, and body portion can thus be saved using the relatively inexpensive carbon steel of common price
The most cost of raw material；
The utility model can not only facilitate tongue to be dismantled with valve body, while preferably tongue can be carried out
R angles are handled, and section is accomplished into preferable effect, also improves production efficiency while tongue fatigue durability is improved, carries
Refrigeration efficiency has been risen, has saved production cost.
Utility model content
The purpose of this utility model is for overcome the deficiencies in the prior art, there is provided a kind of double tongue refrigerator pressures of ultra high efficiency
Contracting machine suction valve chip, to solve, current refrigerator compressor air suction valve block tongue fatigue performance is poor, production and processing is difficult, light is adornd
The technical problem that time is long, production cost is high and refrigeration efficiency is low.
The technical solution adopted in the utility model is as follows：
