Embodiment Construction

[0035] The present invention will be further described in detail below with reference to the drawings and specific embodiments, but the present invention is not limited to these embodiments.

[0036] Such as Figure 1 to Figure 7 As shown, an exhaust valve plate assembly for a reciprocating compressor includes a valve plate 4, a lift limiter 1 and an exhaust valve plate 3. The exhaust valve plate assembly also includes a valve reed 2 and an elastic Damping structure 5. The valve plate 4 is provided with a seating groove 41 for installing the lift limiter 1, the valve reed 2 and the exhaust valve plate 3. The lift limiter 1, the valve reed 2 and the exhaust valve plate 3 Stacked in order from top to bottom at the placement groove 41.

[0037] The head of the lift limiter 1 is provided with a first buckle 16 and the tail of the lift limiter 1 is provided with a second buckle 17, and the lift limiter 1 passes through the first buckle 16 and the second The buckle 17 is provided on t...

Abstract

The invention discloses an air release valve plate assembly for a reciprocating compressor. The air release valve plate assembly comprises a valve plate, a lift limiter and an air release valve block,and further comprises a valve spring piece and an elastic damping structure; a placement groove for installing the lift limiter, the valve spring piece and the air release valve block is formed in the valve plate, the lift limiter, the valve spring piece and the air release valve block are stacked at the placement groove from top to bottom in sequence, and an air release hole is formed in the placement groove; the head of the valve spring piece and the head of the air release valve block are compressed and fixed under the action of the lift limiter, and the tail part of the valve spring pieceand the tail part of the air release valve block can move up and down under the air flow action of the air release hole; when the valve spring piece and the air release valve block move upwards, thevalve spring piece makes contact with the elastic damping structure, and under the action of the elastic damping structure, the valve spring piece cannot make direct contact with the lift limiter. Bymeans of the air release valve plate assembly, the phenomena that the valve block shakes, and closing of the valve block is delayed are reduced, the impact of the valve block on the lift limiter in the opening process is buffered, the service life of the valve block is prolonged, and the noise is reduced.

Description

Technical field [0001] The invention belongs to the technical field of refrigeration compressors, and particularly relates to an exhaust valve plate assembly for a reciprocating compressor. Background technique [0002] The compressor is an important part of the refrigerator. Its main function is to supply the refrigerant to the entire refrigeration cycle system. The refrigeration compressor has two main working processes to realize the function of supplying the refrigerant. One is the suction process and the other is the exhaust process. The gas process and the exhaust process are mainly realized by the reciprocating movement of the piston of the refrigeration compressor. In order to realize the two processes, the valve plate assembly must also be matched. The valve plate assembly is composed of a suction valve plate, a valve plate and an exhaust valve plate. , The valve plate assembly mainly provides a function of controlling the gas flow direction, because both the suction pro...
