1000 litre lpg gas storage tank

Safety Valve A safety valve is a safety device that automatically opens to relieve pressure when the pressure in the liquefied petroleum gas storage tank is too high. Storage of liquefied petroleum gas requires a fully spring-loaded safety valve. The opening pressure must not be higher than the design pressure of the storage tank. Storage tanks over 100 m3 must be equipped with 2 or more safety valves. Install a valve between the safety valve and the storage tank. Fully open the valve port and seal or lock the lead. A safety valve shall be provided with a discharge pipe whose diameter must not be smaller than the outlet diameter of the safety valve. The safety pipe entrance of the above-ground storage tank safety valve should be at least 2 m higher than the storage tank operating table and at least 5 m above the ground. The pressure relief pipe entrance of the underground storage tank safety valve should be at least high. 2.5 m from the floor, the top of the supply hose or collective supply hose should have an elbow or a watertight cap to prevent water from accumulating on the hose. The manufacturer of the safety valve must have the relevant special equipment manufacturing license. The factory must have a safety valve qualification certificate. And the relevant medium of the qualification certificate must be liquefied petroleum gas. Check the safety valve once a year. When two or more safety valves are installed in the storage tank The opening pressure of one of them does not exceed the designed pressure. and the opening pressure of the residual safety valve can be appropriately increased, but not more than 1.05 times, should not be the design pressure of the storage tank.
