Lift limiter for compressor

Abstract

The invention discloses a lift limiter for a compressor, which comprises a lift limiter body (2) arranged on an exhaust hole (1) of the compressor, the lift limiter body (2) There is an exhaust valve (3) between the exhaust hole (1); one end of the lift limiter body (2) is set as an upwardly tilted part (4), and the lift At least one groove (5) is evenly provided on the lower surface of the upwardly tilted part (4) of the limiter body (2); a shock absorber (6) is provided on the groove (5); The other end of the stroke limiter body (2) is provided with a fixed installation hole (7). The invention reduces the contact stress between the exhaust valve plate and the lift limiter body by being used for the lift limiter of the compressor, reduces the impact caused by the exhaust valve plate on the lift limiter body, and improves The service life of the lift limiter body is improved, the noise and vibration are reduced, and the service life of the exhaust valve plate is also prolonged.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a lift limiter for a compressor. Background technique [0002] A compressor is a device that compresses a low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure refrigerant gas, and is the heart of the refrigeration system. There is a cylinder inside the shell of the compressor. When working, low-temperature and low-pressure refrigerant gas enters the cylinder from the intake pipe. After the cylinder compresses it, high-temperature and high-pressure refrigerant gas is discharged from the exhaust pipe, which provides power for the refrigeration cycle. , so as to realize the refrigeration cycle of compression, condensation, expansion and evaporation, which is widely used in the field of refrigeration appliances, such as air conditioners, refrigerators, etc., need to use compressors. Generally, the lift limiter of the compressor is mainly obt...

AI Technical Summary

Problems solved by technology

During the working process of the exhaust valve, the discharge and inhalation of the gas between the exhaust valve and the lift limiter will cause the exhaust valve to be hindered by the gas when it is lifted up and stick to the lift limit when it falls. When the exhaust valve is slowly detached from the lift limiter, some of the discharged gas refrigerant will flow back into the cylinder, causing a serious drop in compressor efficiency; moreover, most of the current lift limiters The exhaust valve plate is opened every time it is exhausted, and the contact stress between it and the lift limiter is relatively large. The exhaust valve plate will impact the lift limiter, generating noise, and making the exhaust valve plate The service life of the machine is reduced, so it needs to be improved
