Working principles
This valve is the pilot type solenoid valve of the second opening valve. Its structure is mainly composed of the pilot valve and the main valve. The main valve adopts the rubber sealing structure. When in normal position, the guide valve is sealed with movable iron core, the pressure in the valve chamber is balanced, and the main valve is closed. When the coil is energized, electromagnetic force is generated to absorb the moving iron core, and the dielectric self-guiding valve mouth in the main valve cavity is discharged, resulting in pressure difference. The diaphragm or valve cup is quickly lifted, and the main valve mouth is opened, and the valve shows a path. When the coil power off, the magnetic field disappeared, the resetting of the active iron core, closed valve mouth, valve and the main valve chamber pressure balance, the valve was closed state.
Description of Usage
1. Please refer to the user manual of the product before installation to see whether it meets your requirements.
2. The pipeline should be cleaned before use, and the filter should be installed if the medium is not clean to prevent impurities from interfering with the normal work of the solenoid valve.
3. The solenoid valve generally works in one direction and cannot be installed in reverse. The arrow on the valve is the movement direction of pipeline fluid and must be consistent.
4 solenoid valve installation of the general body horizontal, vertical upward coil, some products can be arbitrarily installed, but when conditions allow the best vertical, in order to increase the service life.
5. The solenoid valve should be heated or heat preservation measures should be set when it reworks in icy places.
6. After the lead wire of the electromagnetic coil (connector) is connected, it shall confirm whether it is firm or not. The contact point of the connecting electrical components shall not shake.
7 to continuous production work of the solenoid valve, the best use of bypass, easy maintenance, do not affect production.
