Valve plate assembly for compressor

Abstract

The invention discloses a valve plate assembly for a compressor. The valve plate assembly comprises a valve plate, an exhaust valve block and an intake valve block, wherein the valve plate is provided with vent holes and inlet holes; the middle of the valve plate is provided with a mounting hole; a connecting component passes through the mounting hole so as to arrange the exhaust valve block and the intake valve block on the valve plate; the vent holes are distributed on the valve plate annularly and enclose the mounting hole; the exhaust valve block has an annular seal surface; the inlet holes are formed on the valve plate annularly and enclose the vent holes; and the intake valve block is annular and has an annular seal surface. Compared with the prior art, the invention has the advantages that: the valve plate assembly is convenient and quick to assemble and maintain, the intake valve block only does axial reciprocating linear motion and cannot repeatedly bend, the impact force of the intake valve block in unit area is smaller, the whole stress is uniform, the service life of the air valve is prolonged, and the operating reliability of the air valve is improved.

Description

technical field [0001] The invention relates to a compressor component, in particular to a valve plate assembly of the compressor. Background technique [0002] At present, the valve plate assembly widely used in common crankshaft connecting rod compressors is mainly reed valve plate structure, such as figure 1 , figure 2 and image 3 As shown, the valve plate assembly includes a valve plate 1a, an exhaust valve plate 5a, an exhaust spring plate 4a, a limiter 3a, a spacer 7a, an intake valve plate 6a and an intake spring plate 8a, and the valve plate 1a is provided with The exhaust hole 11a and the air intake hole 12a, the screw 2a connects one end of the spacer 7a, the limiter 3a, the exhaust spring piece 4a and the exhaust valve piece 5a to the first surface of the valve plate 1a in sequence and uses the nut 21a Fixed, the other end of the exhaust valve plate 5a is facing the exhaust hole 11a, one end of the intake valve plate 6a is fixed on the second surface of the v...

AI Technical Summary

Problems solved by technology

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