Pipeline burst prevention valve assembly

Abstract

The invention discloses a pipeline burst prevention valve. The pipeline burst prevention valve is provided with pressure buffer cavities, when the pressure intensity in a pipeline is too large, the valve can automatically guide fluid into the buffer cavities inside the valve, so that the pressure intensity in the pipeline is reduced, and then the pipeline is protected and prevented from bursting;the two pressure buffer cavities are arranged, when the pressure in the first-stage buffer cavity exceeds the pressure regulation and control limit, the fluid can be guided into the second-stage buffer cavity, so that the pressure regulation capability of the pipeline burst prevention valve is improved; and an information feedback function is achieved, signals can be rapidly fed back to an alarm information device for alarming, and the arranged pressure buffer cavities can guide the fluid in the cavities back to a main pipeline in time when the pipeline pressure recovers to be normal, so thaton one hand, resource waste and maintenance cost are avoided, and on the other hand, the situations that the external environment is polluted and harmed and even personnel poisoning and death are caused due to the fact that toxic and harmful substances in the pipeline leak to the outside are avoided.

Description

technical field [0001] The invention belongs to the technical field of immunological reaction devices; in particular, it relates to a component of an anti-pipeline burst valve. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. Functions such as reverse flow, voltage stabilization, shunt flow or overflow pressure relief. Valves are widely used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The control of the valve can adopt a variety of transmission methods, such as manual, electric, Hydraulic, pneumatic, turbine, electromagnetic, electro-hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive, etc.; can act according to predetermined requirements under the action of pressure, temperature or ot...

AI Technical Summary

Problems solved by technology

[0003] Existing valves are too simple in structure and single in function, unable to provide effective feedback and response to emergencies in the transportation process. Therefore, this type of valve, especially the valve used in pipelines that transport corrosive or toxic and harmful substances , when the internal pressure of the pipeline is too high, ordinary valves cannot effectively relieve the pressure of the pipeline, resulting in the burst of the transportation pipeline, which in turn leads to the leakage of the internal transportation materials. Large pollution and hazards, even lead to personnel poisoning and death. At the same time, ordinary existing valves cannot effectively feedback and alarm the abnormal pressure inside the pipeline. Therefore, it is imminent to develop a valve with an alarm function to prevent pipeline bursts.
