After using the solenoid valve for a period of time, it may become stuck and blocked, resulting in poor closing. This phenomenon is also quite common. We need to first find the cause before accurately handling it. Now, let's talk about how to deal with the blockage phenomenon of the solenoid valve?
1、 The main reason is that impurities in the pipeline enter the solenoid valve during the discharge process of the medium, causing the valve core to get stuck or unable to close or open when the frictional resistance is greater than the spring recovery force.
2、 Check if the seal is worn, and if there is any damage, replace it with a new seal.
3、 In case of malfunction of the solenoid valve, in order to isolate the solenoid valve in a timely manner and ensure the normal operation of the system, please install manual valves and bypass devices before and after.
4、 Check for impurities in the medium, whether the old pipeline will leak iron filings, and install filters in a timely manner.
5、 Clean thoroughly in a timely manner, and be careful not to leave any residue during cleaning, otherwise the residue will enter the interior of the solenoid valve during the exhaust process, causing blockage.
