Exhaust valve assembly, compressor and air conditioner

Abstract

The invention provides an exhaust valve assembly, a compressor and an air conditioner. The exhaust valve assembly comprises a flange (1) and an exhaust valve set, a valve seat (2) is arranged on the flange (1), an exhaust port (3) is formed in the valve seat (2), the exhaust valve set comprises an installation seat (4), an elastic piece (5) and a valve block (6), the installation seat (4) is installed on the flange (1), the valve block (6) is located between the exhaust port (3) and the elastic piece (5), one end of the elastic piece (5) abuts against the valve block (6), and the other end of the elastic piece abuts against the installation seat (4). At least two protruding parts (7) are arranged at the end, facing the exhaust port (3), of the installation seat (4), the protruding parts (7) are arranged in the circumferential direction of the installation seat (4) at intervals, and the valve block (6) moves in a guide space formed by the protruding parts (7). According to the exhaust valve assembly, the area of an airflow circulation channel can be increased, fluid resistance is reduced, exhaust losses are reduced, and the performance of the compressor is improved.

Description

technical field [0001] The present application relates to the technical field of compressors, in particular to an exhaust valve assembly, a compressor and an air conditioner. Background technique [0002] An end seal assembly is disclosed in the related art, and the end seal assembly includes: an end seal and an exhaust valve. There is a mounting hole on the end seal, and an exhaust port is opened at the bottom of the mounting hole. The exhaust valve includes a lift limiter, an exhaust valve plate and an elastic member. The mounting hole is a round hole with an internal thread, and the lift limiter The outer peripheral surface of the limiter has an external thread that matches the internal thread. The lift limiter is connected with the mounting hole through threads. The bottom is in contact, and one end is in contact with the valve plate, pushing the exhaust valve plate to close. [0003] However, in this end seal assembly, in order to ensure the threaded assembly effect b...

Problems solved by technology

[0003] However, in this end seal assembly, in order to ensure the threaded assembly effect between the lift limiter and the mounting hole, the fitting area of ​​the threaded wall must be large enough. However, due to the large blocking area of ​​the threaded wall, the airflow passage only has side passages. hole, the side through hole area is limited, the flow area is small, so it causes a large exhaust loss and reduces the performance of the compressor
