Description

Technical Field

[0001] The utility model relates to the technical field of exhaust valves, in particular to an exhaust valve for a compressor. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle. The compressor exhaust valve is an indispensable component of the compressor.

[0003] Most of the existing compressor exhaust valves and compressor air pipes are connected and assembled using multiple bolts. This connection method has cumbersome and time-consuming operation steps, and is troublesome to install and disassemble. In addition, most traditional exhaust valves are one-piece structures, and the internal valve plate, spring and lift limiter are difficult to disassemble and replace. In the event of a failure, the entire exhaust valve needs to be replaced, which has a high cost and is prone to waste of resources.

[0004] To this end, we propose an exhaust valve for a compressor. Utility Model Content
