Oxygen valve, as the opening and closing device for conveying oxygen pipe in metallurgical industry, has many especially strict requirements compared with other general valves. Because oxygen is flammable and explosive dangerous goods, it is necessary to prevent leakage, anti-static, fireproof flowers, in order to avoid accidents. In the structure, the design is: when the disc opens and closes, the stem only rises and falls but does not turn, effectively reduces the sealing pair wear, packing wear and upper seal wear; The side flange is equipped with ground screw to avoid electrostatic spark; The exposed part of the valve stem is sealed with plexiglass to prevent dust and oil.
