Embodiment 1-6

[0047] Prepare the valve plate as follows:

[0048] (1) Clean and preheat the mould, and apply the demoulding machine;

[0049] (2) Use epoxy resin to impregnate single-oriented fibers to form a prepreg;

[0050] (3) the above-mentioned prepreg is arranged in the mould;

[0051] (4) Mold clamping and fixing, injection of epoxy resin, compression molding;

[0052] (5) Use ethylenediamine to solidify and release the mold to obtain a fiber-reinforced epoxy resin sheet (i.e. a fiber-reinforced epoxy resin material);

[0053] (6) The suction valve piece and / or the exhaust valve piece cut into the desired shape by laser.

[0054] Among them, the composition (volume content) of the fiber-reinforced epoxy resin in Examples 1-6, as well as the number and thickness of the prepared suction valve sheet and exhaust valve sheet are shown in Table 1.

Abstract

The invention relates to the field of refrigeration household appliances, and discloses a valve plate used for a refrigerator reciprocating type compressor, the refrigerator compressor and a refrigerator. The valve plate used for the refrigerator reciprocating type compressor is made of fiber-reinforced epoxy resin composites. The valve plate has the good chemical resistance and size stability, due to the large damping factor, when the valve plate is used for the refrigerator compressor, high-frequency noise generated by impact between an air suction valve plate valve tongue and a valve deck plate, and an exhaust valve plate and a lift limiter can be reduced, meanwhile, due to the small proportion, air suction and exhaust losses can be reduced, and the energy efficiency of the compressor is improved.

Description

technical field [0001] The invention relates to the field of refrigeration household appliances, in particular to a valve plate used for a reciprocating compressor of a refrigerator, a refrigerator compressor and a refrigerator. Background technique [0002] The valve group is usually called the "heart" of the compressor, and the suction and discharge valves are an important part of the valve group. It can be seen that the suction and discharge valves are the core of the components of the compressor, which will directly affect the To the energy efficiency, noise and vibration of the compressor and other performance parameters. Therefore, the following material properties are important considerations when selecting materials for suction and exhaust valves: [0003] (1) Chemical resistance: When the compressor is running, it contains refrigerant and lubricating oil inside, and it must be guaranteed not to chemically react with the above two types of substances; [0004] (2) ...
