[0002] The compressor is a driven fluid machine that can lift low-pressure gas into high-pressure gas. It is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the operation of the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). The gas valve is an important component of the compressor and is a vulnerable part.

[0003] During the assembly process of the existing compressor valve group assembly structure, the spring connected to the valve seat is generally placed directly in the groove, which causes the spring to shift or detach from the placement groove when the hole position is adjusted after the valve plate and valve seat are subsequently covered on top of it, thereby reducing the assembly efficiency of the valve group. Utility Model Content

A compressor valve group assembly structure is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A compressor valve assembly structure, comprising:

[0007] A valve cover, wherein a groove is provided inside the valve cover, and a magnet sheet is bonded to the inner bottom of the groove, a spring is adsorbed on the top of the magnet sheet, and a valve sheet is provided above the spring, a valve seat is installed above the valve sheet, and a lift limiter is provided on the outer sleeve of the valve seat, a bearing is installed in the middle of the top end of the valve seat, and a nut is passed through the inner wall of the inner ring of the bearing, and a screw is inserted into the inside of the nut.

[0008] Preferably, the diameter of the spring is equal to the inner diameter of the groove, and the spring and the groove form a detachable structure through a magnet sheet.

[0009] Preferably, the nut and the valve seat form a rotating structure through a bearing, and the nut and the screw are threadedly connected.

[0010] Preferably, the lift limiter is a ring-shaped structure, and the lift limiter is connected to the valve seat via a slider and a slide groove.

[0011] Preferably, the magnet sheet and the groove are bonded to form an integrated structure.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] In the utility model, a valve cover, a groove, a magnet sheet and a spring are provided, so that the end of the spring placed in the groove is adsorbed by the magnet sheet, so that the connection between the spring and the valve cover is stable, so that the spring of the valve group can stand stably in the groove and play a role during the assembly process, thereby preventing the spring from tilting or falling off the groove of the valve cover, which would require manual correction continuously, thereby affecting the assembly effect.
