With the development of modern manufacturing industry, more and more enterprises realize the integration of intelligence, like pneumatic, electric series by valve actuator or valve device to realize remote control Reduce the burden of human resources by the majority of users of the favor.
Pneumatic actuator valves are compressed air operated valves. Pneumatic actuator valve procurement only clear specifications, categories, pressure to meet the procurement requirements, can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
Installation And Application Of Pneumatic Actuator Valve
(1) Before installation and use of pneumatic valve, the valve must be installed before the inspection and switch operation test. Only in the normal operation of the conditions, can be installed to use.
(2) Pneumatic valve installation to make the valve and Pipeline Flange as far as possible concentric, and add support fixed. Can not make the ball valve by other external force, so as not to damage the valve in the seal and valve deformation. Causing valve failure and valve damage and can not be used.
(3) To ensure that the power supply of the balloon valve and pneumatic components must be clean, as far as possible without oil and water. Cleanliness should be less than 0.4 microns.
(4) Before connecting to the gas source, the gas supply pipeline, the gas source interface and the switch must be cleaned in order to prevent the failure caused by the dirt and sediment from the dirty belt of the pipeline rushing into the pneumatic execution unit.
(5) For connection of pneumatic actuator, solenoid valve, positioner, filter, pressure reducing valve, etc. , copper or nylon pipe can be used. To prevent dust and reduce noise, muffler or muffler throttle valve should be installed in exhaust port.
(6) After installation, the pneumatic valve should be tested, the pneumatic actuator pressure to the rated value, the pressure is 0.4~0.7 MPA, pneumatic ball valve switch test, observe the opening and closing of the valve. Should turn flexible non-blocking phenomenon. In the switch such as the blockage phenomenon can increase the air pressure, repeatedly switch to switch the valve can be flexible.
(7) When installing and debugging the switch type pneumatic valve, first use the manual device to debug (the manual button on the solenoid valve), after the normal action in power debugging.
(8) Pneumatic valve should be regularly maintained stem rotation, should be three months refueling (oil) once. The pneumatic execution unit and the air filter cooperating with it are discharged and polluted regularly. Under normal circumstances, check once every six months, once a year overhaul.
