What is the function of a pressure relief valve?
1 Answers
The function of a pressure relief valve: To protect the pressure within equipment and pipelines within the set pressure range, preventing unexpected incidents. Pressure relief valves mainly fall into two structural categories: spring-type and lever-type. The spring-type relies on the force of the spring to seal the valve disc and seat, while the lever-type depends on the force of the lever and counterweight. Characteristics of pressure relief valves: 1. Accurate and consistent safety and stable pressure; once overpressure occurs, the pressure relief valve can fully open to promptly relieve pressure. 2. Adjustable closing speed to eliminate pressure fluctuations. 3. The diaphragm transmission mechanism minimizes operational lag. 4. Can be installed in any position, allowing for maintenance and inspection without altering the pressure setting or removing it from the pipeline.
