Thread Content
Pressure vessels such as towers and tanks are generally equipped with safety valves. What is the purpose of the bypass line of a safety valve, and how should its size be determined?
The function of the safety valve bypass is primarily to direct the excess pressure gas released by the safety valve to a safe location, preventing potential hazards or pollution that could result from its direct release into the environment. It can also be used to reduce noise and vibration when the safety valve opens, thereby protecting the equipment. The size of the bypass line is usually determined based on the discharge capacity of the safety valve, the flow requirements of the system, and the requirements of the discharge path. Generally, the following aspects need to be considered: the nominal diameter of the safety valve, the nature and temperature of the substance being discharged, the length of the pipeline, and the number of bends, etc., to ensure that the fluid can be discharged smoothly without causing blockages. .
