Installation and maintenance is undeserved, can cause the pneumatic pneumatic valve flange performance degradation

Pneumatic pneumatic valve flange is three eccentric structure and the level of metal seal type pneumatic seat control pneumatic pneumatic valve, metal hard seal with one-piece pneumatic valve shaft design, in case of changes due to the line pressure pneumatic valve shaft displacement and bushing of dustproof design, prevent the pipeline fluid into the internal cause of pneumatic valve pneumatic valve shaft axis to turn, except the body center center does not overlap with the pneumatic valve shaft and interference Angle offset, also make the pneumatic valve to open in time from the seat, so the pneumatic valve seat is not easy to wear and tear, closing the close tight sealing the stability, increase the service life of the pneumatic valve, sealing performance.
pneumatic flange pneumatic valve is to use the midline structure design, the main structure by the pneumatic valve pneumatic valve body, plate, pneumatic valve seat, pneumatic valve and actuator components, and can according to different medium medium physical and chemical properties, choose the corresponding material corrosion resistance, light resistance, aging resistance, can be used in water supply and drainage, air conditioning, petroleum, chemical, food, energy systems and other fluid on the pipeline as the adjusting and intercepting device is used. Pneumatic pneumatic valve flange installation are in good condition, can affect the efficiency of equipment, and pneumatic pneumatic valve flange maintenance is also related to the equipment performance. Improper installation or lack of maintenance, can cause used pneumatic valve performance degradation, in order to avoid danger, users should be duly testing maintenance of pneumatic pneumatic valve flange.
install pneumatic pneumatic valve flange of the five elements:
1, the plate installed on the diameter of the pipe direction.
2, when installation, plate to stop in the closed position.
3, open position should be according to the board to determine the Angle of rotation.
4, with the ventilation valve pneumatic valve, open the ventilation should be taken before opening valve.
5, should be in accordance with the manufacturer's installation instructions for installation, weight heavy flange pneumatic valve, pneumatic shall set up the basis of stability.

flange of the pneumatic valve pneumatic maintenance:
1, add the location of the signal device. When running in the pneumatic valve in deviating from the fully open position, the signal, so the bright light plate, central control room operators according to signal judgment is accident rushed off or close the pneumatic valve parts.
2, standard part of the general treatment measures of blunt shut, can lift the oil source of pneumatic valves, until fully open signal in the pneumatic valve down again.
3, improve the quality of its maintenance. Because of its large volume, and positioning, to solve the problem of axis of rotation in place, needs to be disintegrated, hoisting, quantity is big, and the limit of the pneumatic valve room space, also hard to do, and for long time, wear and tear, the collapse of the overhaul is also difficult to ensure the quality. Currently is by adding gasket to adjust the center position, and solve the problem of the pneumatic valve itself. Improve maintenance technique, make the pneumatic valve fully open after plate valve parallel to the flow of water.
4, improve relay device sealing performance, replace the better sealing material, to open relay device piston cavity filling oil on a regular basis.
5, at inlet water monitor, to monitor water movements, and increase in the pneumatic valve operation procedures, a regular work content per week to start the oil and gas valve, oil oil filled to the relay device.
