After exhaust valve plate in the utility model is handled through surface heat, can also adopt suitable shot-peening and surface carburization process treating to improve the degree of finish and the intensity of exhaust valve plate.
The utility model can increase the thickness of Bearing Installation groove, thereby strengthen the rigidity of bearing, and can reduce bearing relief opening clearance volume amount to a greater extent, strengthen the strength and stiffness of bearing simultaneously, worsen thereby reduce valve seat distortion and bearing rigidity, finally reach the effect of the service behaviour that improves rotary compressor.
Because crooked snubber coincide mutually and surrounds the space jointly with exhaust valve plate meeting in exhaust process of bending, when exhaust valve plate has just been opened when carrying out exhaust, the gas that remains in this space is difficult to discharge, exhaust valve plate is formed certain exhaust resistance, so the utility model snubber is provided with air outlet hole, aforesaid gas in time can be discharged the Safety performance when improving compressor operating.
The utlity model has simple and reasonable, preparation process good, the good rigidly of bearing, clearance volume are little, the high working efficiency of compressor, advantage of wide range of application.
