AI Technical Summary

Technical Problem

The sealing effect between the valve disc and the valve body in the breathing valve is poor, resulting in fluctuations in the pipeline pressure and affecting the working performance of the machinery.

Method used

A breathing valve is designed, and a first seal is provided between the valve disc assembly and the inner wall of the valve body to achieve a sealing connection, and a sealing seat and a runner hole are provided on the inner wall of the valve body to ensure that the valve disc assembly can be effectively sealed in different states.

Benefits of technology

It effectively avoids internal leakage between the valve disc assembly and the valve body, ensures the stability of pipeline pressure, thereby improving the performance of mechanical operation, and realizing the suction and reverse stop functions of the medium.

Abstract

The utility model relates to the technical field of valves, and discloses a breather valve which comprises a valve body and a valve clack assembly, and the valve body is provided with a conveying cavity and a suction cavity. The valve clack assembly is movably arranged in the valve body and comprises a valve clack body and a first sealing piece. The valve clack assembly has a closed state in which the valve clack assembly abuts against the inner wall of the valve body in a sealed mode and an open state separated from the inner wall of the valve body. When the pressure of the conveying cavity is lower than the designed pressure of the pipeline, the valve clack assembly is in an open state, the conveying cavity communicates with the suction cavity, and the conveying cavity sucks a medium; when the pressure of the conveying cavity is larger than or equal to the designed pressure of the pipeline, the valve clack assembly is in a closed state, the conveying cavity and the suction cavity are blocked, and non-return of a medium is achieved. According to the breather valve, the suction cavity and the conveying cavity of the valve body can be sealed and blocked, and inner leakage is avoided. In this way, the good sealing effect between the valve clack assembly and the valve body can be guaranteed, the stable pressure in a pipeline is guaranteed, and therefore the mechanical operation performance is guaranteed.
