Spring type safety relief valve  

Safety relief valve is an important safety protection device in industrial equipment, which is simply used to control pressure relief. With the continuous improvement and development of modern production processes and the upgrading of industrial equipment and technology, safety valves have also been more widely and deeply applied. 1、 Working principle of safety relief control valve The working principle of a safety relief valve is based on the principle of pressure relief. Like a Pressure relief valve, its main function is to open the valve to provide a channel for high-pressure gas or medium to be released, ensuring that the pipeline pressure does not exceed the predetermined value, thus achieving the goal of protecting equipment and personnel safety. Normally, a safety relief valve is designed to be located at the discharge port in the pipeline. When the pressure in the pipeline exceeds the specified value, the safety relief valve automatically opens, allowing some medium or gas t…
