Steam solenoid valve fault detection techniques

Steam solenoid valves after withstand electrical control signal can take the initiative to open or close the valve, to achieve off pipe steam or flow conditioning control, and thus the system in the steam temperature, flow, pressure and other parameters automatically adjust or long-distance control solenoid valve. Because the steam solenoid valve to use textiles, printing, plastics, chemical, pharmaceutical, rubber, building materials, machinery, electrical appliances, food, such as automatic control system, the use of extremely broad. Following small for us to introduce, steam solenoid valve problems arise after the investigation tips.
1, if the lugs loose or thread off, electric solenoid valve shall be fastened thread.
2, coil burn, remove the solenoid valve wiring, measured with a multimeter, if open, the solenoid valve coil burned out.
3, steam solenoid valve stuck. Cooperation gap solenoid valve slide valve sleeve and spool with a small (less than 0.008mm), are usually one-piece installation, when a mechanical impurities into or too little lubricant, it is easy to get stuck.
4, the lack of air pressure leakage will form, making forced opening and closing valve is difficult, because the gasket is damaged or slide valve wear and the formation of several cavity channeling gas.
