The safety valve is a special valve in which the opening and closing member is in a normally closed state under the action of an external force. When the pressure of the medium in the equipment or the pipeline rises above a specified value, the medium is prevented from exceeding the specified value by discharging the medium outside the system. Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. Note The safety valve must be pressure tested before it can be used.
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.
