Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1-4, a valve plate assembly of a compressor comprises a valve plate 1 and a valve plate 2, wherein the valve plate 1 comprises a valve plate body 11, and an exhaust hole 14 is formed in the valve plate body 11; the valve plate 2 comprises a valve plate body, fins 22 and tongues 21 are arranged on the periphery of the valve plate body at intervals, and the number of the tongues 21 is equal to that of the exhaust holes 14 and the positions of the tongues are in one-to-one correspondence; the fin 22 is riveted with the valve plate 1, and the reed 21 is located on the exhaust hole 14 to close the exhaust hole. This application carries out the riveting with valve plate 1 and valve block 2 and connects, has avoided the valve block to take place to shift, drop, many dress, neglected loading scheduling problem in the product assembly process, has improved the sealing performance between valve block and the valve plate, can finally improve the running performance of compressor, noise abatement.

In order to facilitate assembly and sealing performance requirements, the valve plate is of an arc-shaped structure, specifically, the valve plate 2 is of an arc-shaped structure from the center to the periphery, and the outer ends of the fins 22 and the tongues 21 are close to the valve plate 1 and are attached to the valve plate 1.

That is, the valve plate is not a flat sheet structure, but an arch structure with a certain radian, namely, the center of the valve plate is upwards convex, and the edge part is downwards, so that when the fin 22 is riveted with the valve plate 1, the cambered surface at the outer end part of the fin 22 is contacted with the valve plate, and the contact tightness between the fin 22 and the valve plate is better under the action of riveting force; therefore, the leakage of the compressor during working is reduced, the internal leakage of the compressor is improved, the performance and the energy efficiency ratio of the compressor are improved, and the power consumption is reduced.
