Quick Pressure Relief Valve

Quick Pressure Relief Valve is an automatic pressure relief device used to protect piping systems or equipment from over-pressure damage. When the system pressure exceeds the set value, the quick pressure relief valve will automatically open to release part of the pressure, so as to prevent the pipeline or equipment from breaking, which is widely used in petroleum, chemical, electric power, metallurgy and other industries.

✦Description of Quick Pressure Relief Valve

A quick pressure relief valve is a safety valve for piping systems that opens quickly when the internal pressure of the pipe exceeds the set value to reduce the pressure of the pipe and prevent pipe rupture or equipment damage.

✦Working Principle of Quick Pressure Relief Valve

1. The valve body is connected to the pipeline, and there is a sealing device between the valve seat and the valve body to ensure the tightness of the valve when it is closed. 2. When the internal pressure of the pipeline exceeds the set value, the control device (such as the spring,! A spiral spring or air pressure device) exerts force on the valve to keep it closed. 3. When the pressure exceeds the set value, the force will overcome the restraint of the control device on the valve, and the pressure will open the valve and quickly relieve the pressure. 4. When the pressure exceeds the set value, the force will overcome the restraint of the control device on the valve, and the pressure will open the valve and quickly relieve the pressure. 5. When the pressure drops to the set range, the control device re-applies the force to close the valve to restore the normal working state of the pipeline. Quick pressure relief valves are commonly used for pressure control in liquid or gas piping systems to prevent over-pressure from damaging pipes and equipment and to protect the safe operation of the system.

✦Product Features and Benefits of Quick Pressure Relief Valve

Quick pressure relief valves are hydraulically driven diaphragm hydraulic control valves that discharge excess pressure when the pipeline pressure is higher than the pre-set maximum. The rapid pressure relief valve is fully opened when the system pressure rises suddenly, rapid response, high accuracy, stable and reliable. Quick Pressure Relief Valve is smooth and stable when closed, and the seal is tight and watertight. 1.Hydraulic Pressure Control System pressure drive Long-term use is still tightly sealed and watertight Set to maintain long-term stability Wide setting range Precise setting with minimal hysteresis 2.Advanced ball design, low fluid resistance and high efficiency The runner has no barrier Single moving part Large overflow 3.Fully supported diaphragm, balanced and stable action Low pressure is required for opening and driving Realize the slow closing of the valve Excellent low-flow regulation performance Effectively prevent diaphragm deformation 4.Well-designed and easy-to-use Can be easily checked online Easily add control functions
