Embodiment Construction

[0025] see in conjunction Figure 1 to Figure 4 As shown, according to the embodiment of the present application, a valve body assembly includes a valve core and a seal 2, the valve core includes a first fixing part 11 and a second fixing part 12, and the first fixing part 11 includes a constriction section and an expansion section. In the diameter section, the sealing element 2 is sleeved on the necking section, and the necking section extends into the second fixing piece 12 , so that the sealing piece 2 is sandwiched between the expanding diameter section and the second fixing piece 12 . By setting the first fixing part 11, when the sealing part 2 is installed, the sealing part 2 is sleeved on the necking section first, and then the necking section is inserted into the second fixing part 12, the assembly process is simple and will not damage the sealing Part 2 causes damage to affect the sealing effect, thereby improving the performance of the compressor.

Abstract

The invention provides a valve body assembly, a compressor and a refrigerator. The valve body assembly comprises a valve element and a sealing piece, wherein the valve element comprises a first fixedpiece and a second fixed piece; the first fixed piece comprises a necking section and an expanding section; the sealing piece is arranged on the necking section in a sleeving mode; the necking sectionextends into the second fixed piece, so that the sealing piece is clamped between the expanding section and the second fixed piece. The invention provides the valve body assembly, the compressor andthe refrigerator, which can prevent the sealing piece from being damaged when the sealing piece is mounted, and ensure good performance of the compressor.

Description

technical field [0001] The application belongs to the technical field of refrigeration, and in particular relates to a valve body assembly, a compressor and a refrigerator. Background technique [0002] In the existing variable capacity reciprocating compressor, a pressure relief bypass hole is provided on the side of the cylinder of the pump body, so that the cooling capacity of the pump body can be adjusted within a small range to achieve the purpose of variable capacity. The opening and closing of the pressure relief bypass hole is realized by setting a slide valve assembly in the pressure relief bypass hole. The slide valve assembly includes a slide valve. When the slide valve slides in the slide groove, the slide valve needs to be sealed. The sealing performance of the slide valve directly affects the performance of the compressor. [0003] The existing slide valve is an integrated slide valve. In order to ensure a better sealing effect and establish a pressure differe...
