Correct installation of electromagnetic valve and solenoid valve related matters needing attention 1, read the product manual carefully before installation, check whether the product meets the use requirements, remember the installation points, do a good job in preparation.
2, pay attention to the cleanliness of the media, if the media mixed with dirt, impurities and other impede the normal work of the solenoid valve, the pipeline should be installed filter valve filter ≥ 60 mesh.
3. The solenoid valve should not be installed in the low-pit area of ​​the pipeline. It should be installed in the discharge pipe of the container. Note that it should not be led out from the bottom of the container, but should be installed on the bottom of the container.
4, if the medium will play the phenomenon of water hammer, then you should choose the function of the solenoid valve with water hammer function or take appropriate precautions.
5. Steam traps should be equipped with steam traps on the inlet side of the solenoid valve, where the nozzles should be tilted.
6. Check whether the parameters on the nameplate are consistent with the parameters of the selected product. The power supply voltage should meet the rated voltage and voltage fluctuation range: AC +10%~-15%, DC+10%~-10%. The coil component should not be disassembled at ordinary times. .
7. Before the solenoid valve is taken over, flush the pipe with a pressure of 0.3 MPa to remove metal powder, seal material residue, and rust from the pipe.
8, solenoid valve is generally oriented, can not be installed, usually on the valve body with "→" indicate the direction of flow of the medium, the installation should be in accordance with the direction of the "→" instructions but the company may sometimes in the vacuum line or under special circumstances There will be proposals to reverse install.
9, to confirm, the solenoid valve itself and its connection with the takeover whether there is leakage.
10. Check the connection of the coil lead wires, especially the three lead wires.
11, electrical components connected to the solenoid valve, such as relays, switches and contactors. The contact should not vibrate when opening the valve, otherwise the work will not be reliable and affect the life of the solenoid valve.
12. The electrical circuit must be connected to the corresponding fuse to protect the electrical circuit.
13. There should be some reserved space for the solenoid valve installation place for daily maintenance and regular maintenance.
14. When installing, fix the valve body with a wrench or pipe wrench, and then screw on the connecting pipe. Do not apply force to the electromagnetic coil assembly to cause deformation and make the solenoid valve difficult to work normally.
15. In the case of insufficient pipe rigidity or water hammer phenomenon, please attach the valve before and after the pipe is fixed with the bracket.
16. When using in a frozen place, heat insulation material must be used to protect the pipeline or install a heater on the pipeline.
17, installation position: general solenoid valve solenoid coil components should be upright, vertical installation in the level of the ground pipe, if subject to space constraints or conditions must be set side by side as the building sewer like pipe or inverted installation , please put forward when selecting the order. Some products have special regulations. Please follow the instructions.
18. When taking over, take care that the sealing material cannot be used excessively. 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. Begin to wind the seal with 2 teeth from the end, otherwise the excess seal tape or adhesive will enter the electromagnetic The internal cavity of the valve caused an accident that prevented normal operation.
2, pay attention to the cleanliness of the media, if the media mixed with dirt, impurities and other impede the normal work of the solenoid valve, the pipeline should be installed filter valve filter ≥ 60 mesh.
3. The solenoid valve should not be installed in the low-pit area of ​​the pipeline. It should be installed in the discharge pipe of the container. Note that it should not be led out from the bottom of the container, but should be installed on the bottom of the container.
4, if the medium will play the phenomenon of water hammer, then you should choose the function of the solenoid valve with water hammer function or take appropriate precautions.
5. Steam traps should be equipped with steam traps on the inlet side of the solenoid valve, where the nozzles should be tilted.
