Why do high-temperature steam solenoid valves sometimes become blocked?Release time: 2018-11-30 Clicks: 61 times
Various kinds of failures will occur after any machine is used for a long time, so it is necessary to have a certain understanding of the various failures of the machine when using it. In the use of high-temperature steam solenoid valves , clogging is a slightly common failure. The high-temperature steam solenoid valve has been used for a long time, and the valve core will be blocked due to the viscosity or oxidation of the medium, which will cause the high-temperature steam solenoid valve to block. The main reason is that impurities in the pipeline enter the solenoid valve during the gas discharge This causes the valve core to become stuck or cannot be closed or opened when the friction resistance is greater than the spring restoring force.
The following are common causes of high temperature steam solenoid valve clogging:
1. When the high temperature steam solenoid valve sprays steam into the cassette due to oxidation, it will enter the cassette with the oxidation powder. Then during the exhaust process, the oxidized powder will pass through the solenoid valve, which will jam the internal plunger, resulting in abnormal temperature rise and the completion of the normal sterilization cycle.
2. When cleaning the sterilizer, care should be taken not to leave residues, otherwise the residues will enter the high-temperature steam solenoid valve and cause blockage during the exhaust process.
3. The chemical instruction cards used by hospitals to detect sterilizers are generally packaged cards. Such instruction cards are not waterproof, and there will be tiny residues left inside the cassette after wetting. Timely cleaning may also block the solenoid valve.
Read the above. Only after understanding the cause of the high temperature steam solenoid valve blockage can we better solve and use it.
