Liquefied petroleum gas pneumatic valves

liquefied gas pneumatic valves and liquefied petroleum gas by the pneumatic valve, pneumatic valve is one of the, is now widely used in production and living, but the market for its users is not very understanding, today small make up here to introduce liquefied gas pneumatic valves for your information.
liquefied gas pneumatic valve, also called door and is one of the most widely used pneumatic valve, it is popular, is due to open and close in the process of friction surface, more durable, opening, manufacturing easy, convenient maintenance, not only suitable for low voltage, and is suitable for high pressure.
liquefied petroleum gas of pneumatic valve opening and closing is plug pneumatic valve, sealing surfaces appear flat or cone, pneumatic valve make linear movement along the centerline of fluid; Liquefied petroleum gas pneumatic valve pneumatic valve stem form of exercise, lifting lever ( Pneumatic valve rod, does not lift the handwheel, also have lift rotating lever ( The handwheel with pneumatic valve rod rotating lifting, nut in pneumatic valve body. Grain tube by pneumatic valve used throughout opened only close, not allowed to adjust and throttling.
liquefied gas pneumatic valve types according to the location of the pneumatic valve stem threads with external thread type, internal thread type. According to the flow of medium, have straight-through type, straight and Angle. By the pneumatic valve points, the form of the seal packing seal by the pneumatic valve and pneumatic valve bellows seal globe.
liquefied gas pneumatic valve is closed principle, rely on the pneumatic valve rod pressure, pneumatic valve sealing surface and the pneumatic valve seat sealing surface fit closely, prevent medium circulation.
