Wear-resistant pneumatic valve valve industry structure _ pneumatic components factory

Wear-resisting of electric valve pneumatic valve is the valve industry pneumatic components factory independent research and development production of high-performance products, one of the main wear-resistant pneumatic valve structural characteristics: (1) the overall design of three, forging a three-stage body design ensures wear-resistant pneumatic valve in high temperature and high pressure under the condition of special conditions such as safety and reliability. (2) the aerodynamic body, the valve seat sealing surface superhard processing, pneumatic body surface wear resistance of the pneumatic valve and valve seat sealing surface using HVOF supersonic spraying hard alloy, to ensure the sealing surface of high hardness, wear resistance, seal grade can reach zero leakage. Dual sealing structure design, (3) on the wear resistance of the pneumatic valve, nasty side hard seal floating valve seat adopt double seal structure design, even if the side of the seat seal failure because of accidental circumstances, the valve still works, so as to improve the wear resistance of the pneumatic valve seal reliability. (4) stem blow-out proof design, stem blow a shoulder proof structure design, even in the case of abnormal pressure valve cavity, also can ensure the stem not blown out by medium. (5) anti-static, fire prevention design, when the fire, wear-resistant pneumatic valve with metal to metal auxiliary seal structure and refractory of the flexible graphite sealing structure effective control of wear-resistant pneumatic valve in the emergency conditions of leakage and leakage. 6 midplane pressure function, when the liquid medium entrapped in the valve lumen due to temperature and evaporation, result in higher lumen abnormal pressure, the pressure is greater than the pipeline pressure medium, the medium pressure inside the lumen can push the seat while pressure relief automatically. All landowners double block and discharge function, and low side seat can independently truncation import and export of the medium, to realize double blocking function; Within the lumen of the rest of the medium can be through valves at the bottom of the relief valve discharge. End up driving mode, can according to user requirements design manual, worm gear, pneumatic, electric or gas liquid linkage drive mode, etc. Wear-resisting PN6 pneumatic valve its nominal pressure. 4MPa~32. DN15 ~ 0 mpa, size 800 mm, the valve body material can choose A105, making, F91, F92, F316, 800 h, etc. , the concrete material can be selected according to the actual working condition, can satisfy with the high temperature and high pressure, strong corrosion resistance and medium containing particulate, bad working conditions, such work in a state of safe and reliable sealing, long service life, convenient operation, small pressure loss, therefore applicable to electric power, oil and gas, chemical, metallurgical and other industrial high temperature and high pressure, such as the stringent conditions. : wear-resistant ceramic valve _ ceramic discharge valve type knife wear resistant high temperature slag discharge gate _ discharge gate valve
