Solenoid valves are electromagnetically controlled industrial equipment used in industrial control systems to adjust the direction, flow, speed, and other parameters of the media. The solenoid valve is controlled by the electromagnetic effect. The main control method is controlled by the relay. In this way, solenoid valves can be combined with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed.
Solenoid valve installation precautions
1. Read the instruction manual of the product carefully before installation to check whether the product fully meets the requirements for use, be familiar with the installation points, and make preparations.
2. Check whether the parameters marked on the nameplate are the parameters of the selected product and whether it is in accordance with the instruction manual.
3. Before the takeover, the pipeline is fully flushed with a pressure of 0.3 MPa to completely remove the metal powder, residual sealing material, rust, etc. from the pipeline.
4. Pay attention to the cleanliness of the medium. If impurities such as dirt mixed in the medium interfere with the normal operation of the solenoid valve, a filter should be installed in the pipeline.
5. Solenoid valve should not be installed in the low-pit area of ​​the pipeline. If it is installed in the discharge pipeline of the container, it should not be led out from the bottom of the container, but should be installed at the bottom of the container.
6. If the medium is subject to water hammer, use a multi-function solenoid valve or take appropriate precautions.
7. The inlet valve of the steam solenoid valve should be equipped with a trap valve. The nozzle should be tilted. The trap valve should be installed in a low position. It is better to install a multi-pass recoil filter.
8. Solenoid valve The shut-off valve is generally oriented and cannot be reversed. Usually the “arrow†is used to indicate the flow direction of the medium on the valve body, and the installation direction is to be installed according to the “arrow†direction.
9. The electromagnetic coil components of general electromagnetic valve should stand upright and perpendicular to the pipeline. Some products have special regulations. Please install according to the instructions. .
10. When taking over, care should be taken not to overuse the sealing material. If the thread is connected, the thread of the thread should be kept within the effective length, and be chamfered with a guillotine at the half pitch of the end, starting from the end of the 2 teeth and winding the sealing tape, otherwise the excess sealing tape or adhesive will enter the electromagnetic Inside the valve, an accident that interfered with normal operation occurred.
11. There should be a certain space reserved for the installation of the solenoid valve so that it can be routinely maintained and regularly maintained.
12. When installing the valve body with a wrench or pipe wrench, and then screwing on the connecting tube, do not deform the coil assembly by force. This will make it difficult for the solenoid valve to work normally.
13. In the case where the pipe is not rigid enough or there is a phenomenon of water hammer, please secure the front and back pipes of the valve with a bracket.
14. When using in a frozen place, protect the pipeline with a thermal insulation material or install a heater on the pipeline.
15. To confirm, there is a leak in the solenoid valve and its connection with the connection.
16. Check the connection of the coil lead wires, especially the three lead wires.
17. Electrical components connected to solenoid valves, such as relays, switches and contactors. The contact should not vibrate when the valve is opened, otherwise the work will be unreliable and affect the life of the solenoid valve.
18. The electrical circuit must be connected to the corresponding fuse to protect the electrical circuit.
19. For the convenience of maintenance and repair operations, or without interruption of continuous production, for the general solenoid valve, it is recommended to use the bypass isolation installation method.
