The invention discloses a valve plate assembly for a refrigeration compressor. The valve plate assembly comprises a valve plate and a valve block. A suction hole and an exhaust hole are formed in the valve plate. The valve block comprises a suction valve block body and an exhaust valve block body which are formed through opposite folding of a sheet. The valve plate is embedded in the part between the suction valve block body and the exhaust valve block body. The front surface of the valve plate is attached to the suction valve block body. The rear surface of the valve plate is attached to the exhaust valve block body. A flexible suction tongue piece is arranged at the position, on the front side of the suction hole, of the suction valve block body. An exhaust valve opening avoiding hole is formed in the front side of the exhaust hole. A flexible exhaust tongue piece is arranged at the position, on the rear side of the exhaust hole, of the exhaust valve block body. A suction valve opening avoiding hole is formed in the rear side of the suction hole. The suction valve block body and the exhaust valve block body are designed on the same sheet, bending forming is carried out, a finished product is generated, the position of the suction tongue piece and the position of the exhaust tongue piece are staggered at the time, and the function of the suction valve block body and the function of the exhaust valve block body are achieved. The valve plate is simple in structure, a die is simple, and only one part is involved. The number of assembling procedures is small, assembling is convenient, fast and accurate, and cost is low.
Description
technical field [0001] The invention is used in the technical field of refrigeration compressors, and in particular relates to a valve plate assembly for refrigeration compressors. Background technique [0002] The main function of the refrigeration compressor is to supply the refrigerant to the entire refrigeration cycle system. The refrigerant supply function of the refrigeration compressor mainly consists of two working processes, one is the suction process, and the other is the exhaust process. The suction process and the exhaust process are mainly It is realized through the reciprocating motion of the piston of the refrigeration compressor. In order to realize the two processes, the valve plate assembly must be included for cooperation. 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 It plays a role in controlling the flow of gas, because both the suction process and the ex...
