Vacuum pressure release valve
Vacuum pressure release valve
The vacuum pressure release valve is mainly used to release positive and negative pressure at the top of the warehouse, and can also be applied to other occasions with explosion-proof requirements. Vacuum pressure release valve is also known as ash storeroom release valve or ash storeroom vacuum release valve. The vacuum pressure relief valve is mainly installed on the top of the warehouse as a kind of ash warehouse protection device. Protecting the ash storage from excessive positive and negative pressures during ash storage air intake and exhaust overpressure and abnormal temperature changes is an essential protection device for the ash storage.
Vacuum pressure release valve consists of flat cover, spring ring, movable ring, diaphragm, retaining ring spring, retaining ring, valve cover, valve seat and so on. When the valve is in the rest position (sealed): When the pressure in the silo or ash storage is maintained within the pressure selected by the valve, the valve cover remains in the rest position. Due to the pressure in the silo or ash storehouse, a force acts on the top surface of the flexible diaphragm to make the diaphragm tightly contact the valve seat, thereby achieving sealing. When the valve pressure is released: When the pressure in the storage bin or ash storage reaches the pressure value selected by the valve, the pressure in the bin overcomes the weight of the valve seat cover, and the valve cover is lifted from the valve seat, and the pressure is released until the storage bin or When the pressure in the ash warehouse drops to the same pressure value selected by the valve, the valve cover returns to the normal position. When the valve vacuum is released: When the pressure in the storage bin or ash storage is lower than atmospheric pressure, a vacuum is generated in the storage bin or ash storage. When the vacuum value drops to the vacuum value selected by the valve, the atmospheric pressure acts on the diaphragm. Lift the vacuum ring to the floating position. At this time, the air enters the storage bin or ash storehouse until the internal vacuum value is less than the selected value. The vacuum ring returns to the normal position and rests on the diaphragm. The vacuum pressure release valve is arranged on the top of the ash storage, and protects the ash storage from excessive positive and negative pressures when the ash storage intake, exhaust overpressure and abnormal temperature changes.
