Electric control valve has a compact structure, light weight, small, pressure drop loss, large capacity of valve, precise flow characteristic, easy maintenance, etc. The whole valve has the characteristics of smooth work, large allowable pressure difference, accurate flow characteristics and low noise. Especially suitable for small leakage, large pressure difference before and after the valve in the workplace. Electrical regulating valve in maintenance, need to check the key parts of what? The analysis is as follows:
1, check the valve seat of the electrical regulator: due to the work of the medium infiltration, fixed valve seat with the internal surface of the thread is easy to be corroded and the valve seat relaxed;
2, check the valve spool: the valve spool is one of the movable parts of the regulator, the erosion of the medium is more serious, the maintenance to carefully check whether the parts of the valve spool are corroded, wear, especially in the case of high pressure difference, the valve spool wear caused by cavitation cavitation phenomenon is more serious. The valve spool which is seriously damaged should be replaced; Check the sealing packing: check whether the asbestos rope is dry, such as the use of PTFE packing, should pay attention to check whether the aging and its mating surface is damaged;
3. Check whether the rubber film in the actuator of the electric regulating valve is aging and whether there is cracking phenomenon.
4, check the electrical regulator between the internal wall: in the occasion of high pressure difference and corrosive media, the inner wall of the valve body, diaphragm valve diaphragm often by the impact and corrosion of the medium, must focus on checking the pressure and corrosion resistance.
