Warehouse pressure safety valve

When abnormal pressure endangers the silo structure, the safety pressure valve is the safety line of defense. This is the reason why immediate action is necessary when there is sudden excessive pressure or excessive pumping inside the silo. Efficient and reliable pressure safety valves are essential equipment for silo systems. When the pressure value is within the preset range, the coil spring keeps the valve cover closed. Three external spring rods keep the outer annular valve cover tightly closed until the pressure generated inside the silo is less than the spring force. When the pressure inside the warehouse is too high or too low, once the pressure value exceeds the preset range, the valve cover will be pushed up to release the pressure. The smaller valve cover covers the central circular opening of the outer valve cover from below. The smaller valve cover is fixed by a single spring rod and pressurized onto the external valve cover by the standard atmosphere inside the silo. During compression, the spring compresses and lowers the valve cover. Air enters from the outside of the silo, ensuring rapid pressure balance and pushing the central valve cover into the closed position. The entire work process does not require manual operation. Widely used at the top of storage tanks and hoppers, usually in conjunction with top dust collectors. The safety valve should be installed vertically and positioned at the gas phase interface of the container or pipeline
