Abstract
The utility model discloses a compressor valve plate, which comprises a substrate, be equipped with the hole boss of inhaling, exhaust, suction hole, exhaust hole, mounting hole boss, mounting hole and rib on the base plate, the mounting hole boss is located the base plate four corners, the suction hole with the exhaust hole site is on the same central line of base plate, the suction hole hole boss shape runner that becomes to breathe in that passes the base plate and inhale, exhausts, the exhaust hole boss shape one -tenth gas -exhausting flow path that passes the base plate and inhale, exhausts, breathe in the runner with gas -exhausting flow path all is arc, and both arc tops are relative. The utility model provides a pair of compressor valve plate through inhale, gas -exhausting flow path's convex design reaches the purpose of noise reduction, has reduced inhaling that the gas produced, exhaust pressure loss, through reducing base plate thickness and reinforce with the rib, the effectual clearance volume who reduces the compressor under the circumstances of guaranteeing valve plate compressive strength has improved the efficiency of compressor.
Description
Technical field
The utility model belongs to technical field of refrigeration compressors, is specifically related to a kind of refrigeration compressor valve plate.
Background technology
Air valve is one of vitals of refrigeration compressor, economy, reliability and the energy effective utilization efficiency of compressor are all closely related with it, therefore, it is " heart " of compressor that air valve is often likened to by people, the quality of its design is directly connected to the quality of compressor performance, the very big interest that the research of air valve has been caused to compressor field workers, people have launched deep research to it in recent years.
The air valve of refrigeration compressor is mainly by inhaling, exhaust valve plate and recessed valve plate composition, so-called recessed valve plate, exactly in order to reduce the clearance volume of compressor as far as possible, increase the displacement of compressor, improve gas transmission coefficient, reach energy-efficient requirement, on the basis of traditional flat valve plate, offer groove, air bleeding valve (sheet) is arranged in groove, reduce the impact of air release valve hole on clearance volume, the valve plate of the matrix exhaust valve port structure of designing, under identical volume of cylinder, it is more in a slight decrease than adopting the clearance volume of traditional flat valve plate design to take recessed valve plate design, and then cause the increase of compressor air-discharging amount, improve the efficiency of compressor, and then improve the efficiency of whole refrigeration system, but the DeGrain improving.
Refrigeration compressor in the past can produce gas in the time that cold-producing medium enters suction system, and build-up of pressure loss, can produce turbulence when exhaust, causes compressor airflow noise to rise, and causes compressor noise large, affects the efficiency of compressor.
Here be mainly on above basis, to consider clearance volume and the combined influence of air valve resistance to compressor efficiency, and the valve plate of compressor is optimized to design.
Utility model content
For prior art deficiency, a kind of refrigeration compressor valve plate that the utility model provides reaches by the circular arc design of suction, grate flow channel the object that reduces noise, before making cold-producing medium enter suction system, effectively cushioned, reduce the gas that cold-producing medium enters suction system, and reduce suction, the pressure at expulsion loss that gas produces, and reduce the generation of turbulence; By reducing substrate thickness and reinforcing with rib, in the situation that ensureing valve plate compression strength, effectively reduce the clearance volume of compressor, and then caused the increase of compressor air-discharging amount, improve the efficiency of compressor.
For realizing utility model object, the utility model by the following technical solutions:
A kind of refrigeration compressor valve plate, comprise substrate, described substrate is provided with suction, steam vent boss, suction hole, steam vent, installing hole boss, installing hole and rib, described installing hole boss is positioned at four jiaos of substrates, described suction hole and described steam vent are positioned on the same center line of substrate, described suction hole forms inspiratory flow road through substrate and suction, steam vent boss, described steam vent becomes grate flow channel through substrate with suction, steam vent boss shape, described air-breathing runner and described grate flow channel are all circular arc, and both arc tops relatively.
Be preferably, between described suction, steam vent boss and described installing hole boss, connect by rib, between described installing hole boss, connect by rib.
Be preferably, the height ratio of the height of described substrate and described suction, steam vent boss, installing hole boss, rib is 2:1.
Be preferably, described suction hole is circle, ellipse, rectangle or rhombus.
Be preferably, described steam vent is circle, ellipse, rectangle or rhombus.
Be preferably, described substrate and suction, steam vent boss, installing hole boss, rib are one-body molded.
The beneficial effect of a kind of refrigeration compressor valve plate of the present utility model is: a kind of refrigeration compressor valve plate that the utility model provides reaches by the circular arc design of suction, grate flow channel the object that reduces noise, before making cold-producing medium enter suction system, effectively cushioned, reduce the gas that cold-producing medium enters suction system, and reduce suction, the pressure at expulsion loss that gas produces, and reduce the generation of turbulence; By reducing substrate thickness and reinforcing with rib, in the situation that ensureing valve plate compression strength, effectively reduce the clearance volume of compressor, and then caused the increase of compressor air-discharging amount, improve the efficiency of compressor.
