Pneumatic valve installation process and maintenance matters needing attention

Pneumatic valve installation process before installation, check the pneumatic valve no missing parts, each part model is correct, check the valve body without sundry, solenoid valve and the muffler internal nonblocking are placed in the closed position, the valve and cylinder. And will be loaded on the valve, cylinder, The installation direction parallel to the valve body or vertical) , see if the screw hole for again, won't have too big deviation, if you have a little deviation, cylinder block turning point, then tighten the screw. And after the installation, debugging was carried out on the pneumatic valve ( Under normal circumstances for gas supply pressure. ~。 MPa） Debugging operation manual operation with solenoid valve opening and closing ( The solenoid valve coil manual operation shall be effective after losing electricity And observe the pneumatic valve opening and closing. If in the process of debugging operation found some difficulty in opening and closing process of the initial valve, after normal, you may need to dispatch cylinder stroke ( The ends of cylinder stroke adjusting screw to adjust a bit at the same time, adjust the need to run the valve in the open position, and then dispatch air off again) Until the valve opening and closing action smooth and closed without any leakage. Also it is important to note that the adjustable type silencer can adjust the valve opening and closing speed, but not too small, otherwise may cause the valve is not action. , have hair before installation should keep dry, not in open air, to check before install the valve pipe, to ensure that the pipe without welding slag etc, foreign bodies, moderate manual open/close the valve body resistance, valve torque matching with the selected actuator torque. , valve connected with the flange specifications correctly, pipe flanges are in conformity with the valve flange standard to the clamp. Recommend the use of special flange valve, flat welding flange shall be used. , verify the welding flanges, valve installation after the completion of welding flanges shall not be made, so as not to burn rubber parts. And the pipe flange are going to have to pack good, and with valve into the. And install all flange bolts, with the hand tight, just, will confirm valve with flange and with the opening and closing of valve, to ensure that the opening and closing flexible. , open the valve fully using a wrench, according to the diagonal order. Tighten bolts, without gaskets, never will bolt screw tight, in case caused serious deformation, valve ring opening and closing torque is too big. Pneumatic valve and maintenance matters needing attention, pneumatic valve in use process, often should keep clean, drive screw thread must be lubricated periodically, found that when a failure, should immediately stop using, find out the reason to remove fault. , packing gland bolts shall be uniformly tight, should not be pressed into crooked state, in order to avoid collision block valve rod movement or cause leakage. , when installation, the valve can be according to the connection device in pipeline directly. In general, can be installed on the pipeline at any position, but need to facilitate the maintenance operation, should pay attention to the flow direction of medium cut-off valve is high, the longitudinal disc below lift check valve can only be installed horizontally. , pneumatic valve, when used only for full open or full close, does not allow for regulating flow, lest sealing surface erosion, accelerated wear and tear. Gate and thread on the globe valve with pour sealing device, the handwheel back to the top position and tighten, to prevent leakage of media from the packing. , pneumatic valve open and close the application at hand, please do not use leverage, or other tools, so as not to damage the valve. The handwheel clockwise to shut down, and vice to open it. , before the installation, should carefully check the valve pressure, size is in line with the use requirement, eliminate the defects caused by the transportation process, and remove the dirt from the valve parts. Valves, long-term storage, should be regularly check, for the leakage of machining surface must be clean, remove dirt, keep on both ends of the valve should be blocked and in an open position, pneumatic valve, the ends of the channel should be blocked and closed, neatly stored in indoor and ventilated dry place, do not heap or in open air.
