Description
Technical field
The present invention relates to exhaust valve plate and Compressor Technology fields, and in particular to a kind of exhaust with diversion function
Valve block and its refrigeration compressor.
Background technique
For the prior art during compressor air-discharging, valve block is bent upwards opening, leans against on valve block baffle, from compressor
The high speed and high pressure gas-liquid mixture that cylinder injection goes out impacts valve block, and for valve block since its thickness is thin, rigidity is low, rushes in the gas of high speed
It hits down, it may occur that similar to the self-excited vibration that flag flutters in the wind, referred to as flutter.It is disconnected that flutter may result in valve block fatigue
It splits, reduces valve structure reliability；Meanwhile the air-flow of high speed is to flow through valve block with a kind of turbulent condition, in valve block lower surface
Many small vortex are formed, microseismic noise is brought, increase compressor noise vibration.
Common exhaust valve plate is tongued structures, and without any other structure at tongue mouth, in the form of a single, structure is simple.
This kind of exhaust valve plate is contacted in assembly with valve plate valve line, and when compressor is run, exhaust valve plate tongue mouth is opened, gas discharge be in from
Bulk state, is influenced by continuous exhaust pneumatic wallop, and exhaust valve plate vibration is larger；And it in this kind of exhaust valve plate opening process, is periodically opened
It opens/closes, and nonlinear characteristic is presented in air motion dynamic behavior, influences valve structure reliability.
Also there is exhaust valve plate to improve in structure, to improve noise, as Chinese utility model patent (publication number:
CN207701327U a kind of exhaust valve plate, the exhaust valve plate) were disclosed in 2018, comprising: tail portion is used for exhaust valve plate
It is fixed on the flange of compressor；Head, it is corresponding with the vent position of compressor, it can be relative to the tail portion to turning over
It rises to open the exhaust outlet of compressor and downward return with the exhaust outlet of close compressor, and in the lower surface on the head
It is upper, be additionally provided with projective structure in downwardly projecting mode, and along the length direction of the exhaust valve plate, the projective structure
Protrusion height gradually rises from the tail portion to the head.The utility model can play flow-disturbing and water conservancy diversion using projective structure
Effect, gas dispersion reduces the flutter and microseismic noise of valve block to the impact force of valve block；But the bulge-structure face is vented
Mouth setting, size and number are restricted, and the slightly bigger closure for influencing whether exhaust valve plate, bulge-structure can be with exhaust
Mouth generates interference；Negligible amounts or it is undersized when diversion effect again it is unobvious, be unfavorable for reduce pulsations.
Summary of the invention
