Working principle of emergency shut-off valve for liquefied gas storage tank

Requirements for the setting of emergency shut-off valves for liquefied gas storage tanks

Structural Design of Liquefied Petroleum Gas Storage Tank

Content

Before the storage tank is officially used, there are necessary valves for the storage tank, and some valves installed for safer use of the storage tank. The working principle of the emergency shut-off valve of the liquefied gas storage tank. It means that in the event of an emergency, the valve will be quickly closed or opened to avoid accidents. The actuator of the emergency shut-off valve can have three options: electric, pneumatic and hydraulic according to the power source.When the liquid level of the liquefied gas storage tank reaches or exceeds the upper limit, the emergency shut-off valve can be used to prevent the material from overflowing the tank. No other pipe fittings or valves shall be installed between the emergency shut-off valve and the nozzle of the liquefied gas storage tank except the connecting pipe, and the distance shall meet the requirements of piping installation, valve maintenance and process.
