Description
Technical Field
The invention belongs to the technical field of refrigeration compressors, and particularly relates to an exhaust valve plate assembly for a reciprocating compressor.
Background
The compressor is an important component of the refrigerator, and mainly has the function of supplying the refrigerant to the whole refrigeration cycle system, the refrigeration compressor mainly has two working processes, one is a suction process and the other is a discharge process, the suction process and the discharge process are mainly realized through the reciprocating motion of a piston of the refrigeration compressor, and in order to realize the two processes, the valve plate assembly is also necessary to comprise the matching of a valve plate assembly, and the valve plate assembly consists of a suction valve plate, a valve plate and a discharge valve plate, and the valve plate assembly mainly has the function of controlling the flow direction of the gas, because the suction process and the discharge process are not separated from the suction or the discharge of the refrigerant.
The compressor is also a main noise source of the refrigerator, and the reduction of the refrigerator noise has important significance for improving the working and living environments of people. The compressor efficiency depends firstly on the air valve, and the abnormal movement (flutter and closing delay) of the valve plate is a main reason for generating extra flow loss and is a main part for generating noise sources.
When the exhaust valve block moves, the tail end of the exhaust valve block is opened firstly due to the flow of gas and directly impacts the lift limiter, and when the curvature of the root of the valve block is equal to the arc of the lift limiter, the valve block starts to be wound with the lift limiter. In order to prevent the exhaust valve from directly striking the lift limiter, it is necessary to add a valve reed between the exhaust valve and the lift limiter as a buffer member, not only to directly reduce damage to the exhaust valve due to repeated striking, but also to reduce noise to some extent.
For the existing exhaust valve structure, two abnormal phenomena of valve plate tremble and delayed closing are easy to occur in the movement of the exhaust valve plate.
By delayed closing is meant that the valve plate after opening impinges on the lift limiter, and after a slight rebound, again impinges on the lift limiter until the valve plate begins to close. The valve plate is closed by the valve plate due to the small rigidity, so that the valve plate is long in closing process and slow in seating speed, and the valve plate is not closed when the piston reaches the dead point position, and the valve plate cannot fall to the valve plate until the piston moves reversely for a period of time.
The judder is that after the valve plate passes over the balance position, the valve plate does not slowly return to the balance position, but is flushed away in the opposite direction, so that the air valve is partially closed, the discharge of a part of air is blocked, the pressure is increased, the valve plate is flushed out of the valve plate again, and the process is repeated. The valve plate may actually contact the valve plate multiple times during the opening cycle of each valve.
The two abnormal movement phenomena can aggravate the damage of the valve plate and improve the operation noise of the compressor.
It is seen that there is a need for further improvements and enhancements in the art.
