International silencing check pneumatic valve should be how to maintenance and maintenance?

silencing check the function of a pneumatic valve is to prevent the flow direction, only allowed to medium flows in one direction. This pneumatic valve is normally automatic work, in a direction of flow of fluid pressure, pneumatic valve open; In the opposite direction of fluid flow, the fluid pressure and pneumatic disc from the overlap of pneumatic disc on the pneumatic seat, thereby cutting off flow. Should not be used in large medium containing solid particles and viscosity.
silencing check pneumatic valve belong to automatic pneumatic valve, its purpose is to prevent the backflow medium pipeline, it is mainly used for medium on the one-way flow of pipeline, only allowed to medium flows in one direction, in order to prevent accidents.
to international representative silencing check pneumatic valve brand on American shield VTON, for example, small make up here introduce silencing check pneumatic valve maintenance and maintenance method.
silencing check pneumatic valve maintenance is as follows:
) Storage transport open-close part should be at the closing device, at the same time, should do the following work:
1) silencing check pneumatic valve disc should be fixed in the open position.
(2) the size at both ends in the mouth with foam board blockage, port must use blank cap plugged, dust, rust, keep the passage clean and face smooth;
3. Proper packaging protective cylinder parts, shock and the touch;
） Silencing check pneumatic valve placed should be smooth, pneumatic drive up, shall not be affected by each other.
） For a long time when placed should be check regularly. Every three months for two channels, seal surface dirt and rust, welding mouth check the situation of the protection, wipe the dirt and rust, besmear again the rust-proof protection.
） In order to prevent medium counter-current, on the equipment, devices and pipeline check pneumatic valve should be installed;
） Silencing check pneumatic valve is suitable for the cleaning medium commonly, should not be used in medium containing solid particles and viscosity is bigger;
） Generally on the level of nominal menstruation mm pipe should choose vertical silencing check pneumatic valve;
） Silencing check pneumatic valve should be stored in dry and ventilated room, moisture, rain, rust.
