Problems solved by technology

[0003] The shape of the suction valve plate of the valve plate is generally a long tongue shape, which will be bent repeatedly during the working process. The stopper is a single-point (or single-line) impact, so the force of this valve is poor and the service life is short. Once the compressor has a liquid hammer, the suction valve is more likely to break

Abstract

A crankshaft type compressor comprises a cylinder body with a cylinder hole and a valve board assembly arranged on the end face of the cylinder hole. The valve board assembly comprises a valve board, discharge valve plates and air suction valve plates. Exhaust holes and air suction holes are formed in the valve board. The exhaust holes are annularly formed in the valve board and surround a mounting hole. Correspondingly, the discharge valve plates are provided with annular sealing faces. The air suction holes are annularly formed in the valve board and surround the exhaust holes. Correspondingly, the air suction valve plates are provided with annular sealing parts. Compression springs, stoppers and corrugated elastic sheets are sequentially arranged on the back faces of the discharge valve plates from outside to inside. Compared with the prior art, the crankshaft type compressor has the beneficial effects that the situation that air flow is rapidly increased is relieved, and the discharge valve plates are protected against impact fractures.

Description

technical field [0001] The present invention relates to a compressor. Background technique [0002] At present, common crankshaft compressors include a cylinder block and a valve plate. The cylinder bore of the cylinder block is provided with a valve plate assembly. The widely used valve plate structure is mainly a reed valve plate structure, such as Figure 6 As shown, the valve plate structure includes valve plate 1a, exhaust valve plate 5a, exhaust spring plate 4a, limiter 3a, spacer 7a, suction valve plate 6a and suction spring plate 8a, and valve plate 1a is provided with The exhaust hole 11a and the suction hole 12a, the screw 2a sequentially connect the spacer 7a, the stopper 3a, the exhaust spring piece 4a and one end of the exhaust valve piece 5a to the first surface of the valve plate 1a and use the nut 21a Fixed, the other end of the exhaust valve plate 5a is facing the exhaust hole 11a, one end of the suction valve plate 6a is fixed on the second surface of the v...
