Overflow valve with pressure relief function
By designing an overflow valve with pressure relief function, the limiting structure and thread combination are used to stabilize the limit, and the overflow valve automatically relieves pressure under high pressure, solving the problem of air explosion caused by excessive pressure at the front end of the pipeline, and improving the stability and life of use.

AI Technical Summary
Technical Problem
The existing relief valves are difficult to prevent pipeline bursting when the front end pressure at the pipe is too high.
Method used
An overflow valve with pressure relief function is designed, including a breathing port, upper cover and main valve body, with an overflow piston and a pressure relief piston inside, which achieves stable limit through the combination of limit structure and threads. The pressure relief channel and pressure relief valve automatically release pressure under high pressure to avoid overpressure in the pipeline.
Benefits of technology
Effectively reduce the gas pressure at the front end of the pipeline, prevent gas explosion in the pipeline, and improve the stability and life of use.

Abstract
According to the overflow valve with the pressure relief function, a limiting structure is arranged in an overflow pressure adjusting cavity, by limiting the moving distance of an overflow piston, when the pressure at the front end of a pipeline is too large, the pressure relief piston is pushed to move, and then a pressure relief valve is opened; according to the pressure relief valve, the overflow piston is arranged in the pressure relief channel, so that overlarge gas pressure passes through the pressure relief channel, the pressure relief valve port and the cavity between the pressure relief piston and the overflow piston and then is exhausted through the pressure relief exhaust port, the gas pressure at the front end of a pipeline is reduced, that is, overlarge pressure in the corresponding pipeline is reduced, and the problem of gas explosion of the pipeline is avoided.
