What should you pay attention to when installing solenoid valves?

What should you pay attention to when installing solenoid valves? 1. Read the instructions of the product carefully before the device, check whether the product can fully meet the application requirements, understand the key of the device, and prepare for the operation. 2. Check whether the parameters marked on the nameplate are the parameters of the selected product, and whether it can be consistent with the operating instructions. 3. Before receiving, use the pressure of 0.3Mpa to flush the pipeline thoroughly, and completely remove the metal powder, residual sealing material and rust in the pipeline. 4. Pay attention to the cleanliness of the medium. If the impurities such as dirt mixed in the medium hinder the normal operation of the solenoid valve, the filter should be installed in the pipeline. 5. The solenoid valve should not be installed in the low recess of the pipeline. For example, it should be installed in the discharge pipe of the container. It should not be taken out from the bottom of the container, but should be placed at the bottom of the container. 6. If the medium will appear as a water hammer, then choose a multi-function solenoid valve or take appropriate precautions. 7. The steam inlet side of the solenoid valve should be equipped with a steam trap, where the receiving should be skewed, the trap should be installed in the low position, and the multi-pass backwash filter should be optimally installed. 8. The flow direction of the solenoid valve is usually oriented, and it is not reversed. Usually, the "arrow" is used on the valve body to indicate the direction of media movement, and the device should follow the "arrow" to indicate the direction. 9. Generally, the electromagnetic coil components of the solenoid valve should be upright and perpendicular to the pipe. Some products have special regulations. Please follow the instructions. . 10. When receiving, it should be noted that the sealing material can not be used excessively. If the thread is connected, the receiving thread should be kept within the useful length and chamfered at the end half pitch with the boring tool at the end half pitch. The end of the 2 teeth starts to surround the sealing band, otherwise the excess sealing tape or adhesive will enter the electromagnetic Inside the valve, the attack is a hindrance to normal actions. 11. There should be a certain reserved space at the solenoid valve device for its normal protection and timing repair. 12. Fix the valve body with a wrench or pipe wrench when the device is installed, and then screw it on and receive it. Do not apply force to the coil assembly to cause deformation, which makes the solenoid valve difficult to work normally. 13. In the case of lack of steel in the pipeline or the appearance of water hammer, please fix the front and rear receiving brackets firmly. 14. When using in a frozen place, use a heat insulating material to protect the pipe or install a heater on the pipe. 15. To admit, the solenoid valve itself and its connection with the receiving area can be leaked. 16. The connection of the coil lead wires should be checked correctly, especially in the case of three lead wires. 17. Electrical components that are connected to solenoid valves, such as relays, switches, and contactors. The contacts should not oscillate when the valve is opened, otherwise the operation will not depend and affect the life of the solenoid valve. 18. The electrical circuit should be connected to the appropriate stable line as protection for the electrical circuit. 19. In order to facilitate the protection and repair work, or to stop the continuous production, the bypass solenoid device is recommended for the general solenoid valve.
