Troubleshooting of Electric Regulatory Valve
Sometimes we will find that the electric regulatory valve will volatile, tweet, this is because the sensitivity of the electric regulator is too high, the appropriate adjustment is too large to change the pressure generated by the actuator and the pressure of the fluid, and the actuator Insufficient thrust, so that the selection of the adjustment valve becomes large, the electric adjustment valve valve is often operated on small opening degree, the medium flow direction is the same as the shutter direction of the valve, and the oscillating in the vicinity of some other places affect the electric regulator valve. And there is no a good support.
If the action of the electric regulating vacuum valve is slow or the adhesion of the medium inside the electric regulator is too high, there is a phenomenon that causes blockage and combo, which speeds up the filler aging and the filler extrusion. The electric two-way regulatory valve is also the case where we must clear the residual media in the inspection of the electric regulatory valve, otherwise hardening the diameters and will increase the difficulty of removal or make the regulating valve different normal use. In particular, puzzle with corrosive media will cause some unnecessary troubles in the regulating valve. Since the amount of leakage of the electric regulator can cause the spool or the valve seat to be corroded, wear; the loose or thread of the valve seat is corroded; the valve seat, the spool has foreign matter; the start point of the valve (electrically opened) or the end point (Electrically closed) is not adjusted.
Introduction valve manufacturer caused by electric regulatory valve manufacturing quality is not strict in the production process, resulting in unqualification of the sealing surface of the sealing surface, the products such as sparp, and Shadow, etc. have not completely removed. The inner leakage of the electric regulator valve caused. Workaround: Re-process the sealing surface.
