Do you know what is the installation knowledge of water solenoid valve? If you want to know, just follow the editor of china Vacuum magnetic valve supplier to have a simple understanding!
1. Solenoid valves are generally directional and cannot be installed reversely. Usually, "→" is used to indicate the flow direction of the medium on the valve body, and the installation must be installed in the direction indicated by "→".
2. Manual shut-off valves should be installed before and after the solenoid valve, and a bypass should be provided to facilitate the maintenance of the solenoid valve in case of failure.
3. If the medium will have water hammer, then a solenoid valve with waterproof hammer function should be selected or corresponding preventive measures should be taken.
4. Flush the pipeline with a pressure of 0.3 MPa before taking over the pipeline to remove the metal powder, sealing material residue, rust, etc. in the pipeline. Pay attention to the cleanliness of the medium. If the medium is mixed with dirt, impurities, etc., which hinder the normal operation of the solenoid valve, a filter valve (filter mesh ≥ 60 mesh) should be installed in the pipeline.
5. A trap should be installed on the inlet side of the solenoid valve for steam, and the connecting pipe should be inclined.
6. Solenoid valve should not be installed in the recessed part of the pipeline. It should be installed in the discharge pipeline of the container. Be careful not to lead out from the bottom of the container, but should be installed slightly above the bottom of the container.
7. When taking over the pipe, pay attention that the sealing material should not be used excessively. 8 Try not to keep the solenoid valve energized for a long time, which will easily reduce the service life of the coil or even burn the coil. That is, the normally open and normally closed solenoid valves cannot be used interchangeably.
The above is the introduction of the editor of china Vacuum magnetic valve supplier: a brief introduction to the installation knowledge of water solenoid valves.
