Liquefied petroleum gas pneumatic valve installation need to pay attention to

liquefied gas belongs to compulsory sealed pneumatic valve pneumatic valve, in pneumatic valve is closed, so must to pressure pneumatic disc, to force a sealing surface does not leak. When medium by pneumatic disc below 6 into the pneumatic valve, operating force required to overcome resistance, is pneumatic stem and packing of the friction force and the thrust produced by medium pressure, close the pneumatic valve force than the pneumatic valves open force is big, so the larger the diameter of the pneumatic valve stem, or pneumatic stem top bending failure happens. Pneumatic valve installation need to pay attention to the liquefied petroleum gas, gold in small make up to answer for you. Pneumatic valve installation and maintenance of the
liquefied petroleum gas (LPG) note:
the handwheel, handle operation of the tube by the pneumatic valve can be installed in any position.
the handwheel, handle and wei mechanism, does not allow for lifting.
the flow of medium should be consistent with the direction arrow shown in pneumatic valve body.
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. It is the closing of the principle, rely on the pneumatic valve rod pressure, pneumatic valve sealing surface and the pneumatic valve seat sealing surface fit closely, prevent medium circulation.
liquefied gas only medium one-way flow pneumatic valve, the installation direction. Its length is greater than the brake the structure of the pneumatic valve, at the same time, fluid resistance is big, long runs, seal reliability is not strong.
liquefied gas pneumatic valve is divided into three categories: straight through, right Angle type and once-through inclined by the pneumatic valve.
the liquefied gas pneumatic valve opens, the opening of pneumatic disc height, for the nominal diameter % ~ %, traffic has reached maximum, said the pneumatic valve to full open position. So by the pneumatic valve fully open position, should be determined by pneumatic disc trip.
