Problems solved by technology

There needs to be a sealing distance between the relief hole and the inner cavity of the cylinder, and there must be a sealing distance between the relief hole and the outside of the cylinder. The design of the exhaust valve plate must meet the requirements of crossing the cylinder wall. Therefore, the exhaust valve plate and the lift The stroke limiter usually needs to be set relatively long, correspondingly, the bearing valve seat is also relatively long, which affects the strength of the bearing bottom surface, which is not conducive to the optimization of compressor performance and cost

Embodiment 1

[0051] refer to Figure 2-Figure 4 , in this embodiment, the valve plate 63 is formed in a substantially elongated shape. Compared with the traditional valve plate 63, the length L of the elongated valve plate 63 can be set to be smaller. The shape of the lift limiter 64 is substantially the same as that of the valve plate 63 , and the shape of the valve plate groove 62 matches the shape of the valve plate 63 .

[0052] The tail portion 642 of the lift limiter 64 is connected by laser welding to the side wall of the valve plate groove 62, and the weld 65 between the lift limiter 64 and the valve plate groove 62 is located on the upper edge of the lift limiter 64 The contact position with the disc groove 62. Thus, the welding process operation is facilitated, thereby facilitating the welding connection between the lift limiter 64 and the side wall of the valve plate groove 62 .

[0053] Further, the weld 65 between the lift limiter 64 and the valve plate groove 62 includes at...

Embodiment 2

[0057] The difference between the exhaust valve assembly of this embodiment and the above-mentioned first embodiment lies in the shapes of the valve plate groove 62, the valve plate 63 and the lift limiter 64, and the relationship between the lift limiter 64 and the valve plate groove 62. 65 positions between the welds. Other structures of the exhaust valve assembly of this embodiment are generally the same as those of the above embodiment, and will not be repeated here.

[0058] refer to Figure 5-Figure 8 , in this embodiment, the weld 65 between the lift limiter 64 and the valve slot 62 is located at the contact position between the tail end edge of the lift limiter 64 and the valve slot 62 . The tail portion 642 of the lift limiter 64 is in the first direction (see Figure 5 with Figure 8 The size in the e2 direction) is smaller than that in the second direction (refer to Figure 5 with Figure 8 In the e3 direction), the first direction is parallel to the line direc...

Abstract

The invention discloses an exhaust valve assembly of a compressor and the compressor with the exhaust valve assembly. The exhaust valve assembly comprises an exhaust valve seat, a valve plate and a lift stopper; an exhaust hole and a valve plate groove arranged around the exhaust hole are formed in the exhaust valve seat, the valve plate is arranged in the valve plate groove, the head of the valve plate can open or close an exhaust hole, and the lift limiter is arranged in the valve plate groove and is located above the valve plate; the tail of the lift limiter and the side wall of the valve plate groove are in laser welding connection; the head of the lift limiter is away from the bottom wall of the valve plate groove, the head of the lift limiter corresponds to the head of the valve plate in the vertical direction, and the tail of the lift limiter corresponds to the tail of the valve plate in the vertical direction; and according to the exhaust valve assembly of the compressor, the shape, the direction and the length of the valve plate groove can be freely adjusted, the influence of the thickness of the air cylinder wall is avoided, laser welding high-precision locating can be carried out, a welding line is fine, deformation is small, assembling of the exhaust valve assembly can be met, and performance of the compressor and optimization of the cost are facilitated.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a discharge valve assembly of a compressor and a compressor having the same. Background technique [0002] In related technologies, the exhaust valve of a rotary compressor needs to be composed of an exhaust valve plate, a lift limiter, and a valve rivet. In the wall, a relief hole with a larger diameter is arranged on the cylinder wall. There needs to be a sealing distance between the relief hole and the inner cavity of the cylinder, and there must be a sealing distance between the relief hole and the outside of the cylinder. The design of the exhaust valve plate must meet the requirements of crossing the cylinder wall. Therefore, the exhaust valve plate and the lift The stroke limiter usually needs to be set relatively long, correspondingly, the bearing valve seat is also relatively long, which affects the strength of the bearing bottom surface and is not conducive to the ...
