Copper pneumatic valve maintenance matters needing attention

, copper oxygen by pneumatic valve installed on the pipeline, should be stipulated in the system design of system strength closely and leakage test, special clean sweep process was carried on.
, manual pneumatic valve should be set by fixed platform, so that the operation and maintenance, manual pneumatic valve, ball diameter greater than mm only in pneumatic valve for pressure difference before and after. MPa are allowed to operate within. When operating, standing on the pneumatic valve side, slow operation. Adjust the use copper oxygen by pneumatic valve can do about it.
by the pneumatic valve, copper oxygen in the transport, storage process, the rain moistureproof and banned oil should be paid attention to.
, often operating pneumatic valves, try choosing pneumatic pneumatic valve.
, to prevent fire, working pressure is greater than. MPa copper oxygen as before, during and after the pneumatic valve shall be connected section copper alloy ( Or stainless steel) Pipe, the length is not less than times the pipe diameter, and no less than. M, and shall not be installed all pipe fittings.
by the pneumatic valve, copper oxygen after stopping for a long time, and then use special cleaning processing should be thoroughly.
, copper oxygen by pneumatic valve connection line or attachment flange gasket should choose annealing softening of aluminium, copper or copper wire.
and to prolong the service life of pneumatic valves, pneumatic brake pneumatic valve and the ball valve should be used fully open and close. Do throttling use should not be partially open. Because partially open, rolling of medium erosion sealing surface of disc and the ball, when medium have impurities, the erosion effect is bigger.
and pneumatic valve installed in as far as possible do not remove when, if you want to remove the installation, please be sure to do identification, especially for brake pneumatic valve, reinstall the gate after direction should be the same as before in the same direction.
, plumbing with pneumatic valves are not allowed to use in the transport of combustible gases, corrosive medium in the pipeline, such as the need to be used in the pipeline, the suggestion of choose and buy special pneumatic valves, such as gas pneumatic ball valve, stainless steel pneumatic valves, etc.
