The safety valve is an important accessory for safety protection of pressure limiting and pressure relief on special equipment. (boilers, pressure vessels, pressure pipes, etc.) Safety valves are generally installed directly on special equipment. His design, manufacture, installation, use, inspection, etc. must comply with the requirements of special equipment, because its operational reliability and performance are directly related to equipment and personnel. Safe and closely related to energy conservation and environmental protection.
The selection of a suitable safety valve should be considered from the following aspects:
1. The structural form depends mainly on the process conditions of the equipment as well as the working medium and characteristics. Generally, the spring type safety valve is often used when the amount of boiler and pressure vessel is not large. Otherwise, it is better to select the full-open safety valve.
2. If the medium is toxic, flammable and explosive, the closed safety valve should be selected.
3. Each safety valve has its own working pressure range. When selecting, it should be selected according to actual needs.
4. The discharge of the selected safety valve must be greater than the discharge amount of the equipment, so as to ensure that part of the medium is removed and the pressure is prevented from rising.
