How to install solenoid valve, correct installation of solenoid valve

How to install the solenoid valve, correct installation of the solenoid valve 1. When receiving the goods, check whether the model and parameters on the solenoid valve plate or label are consistent with the model and parameters proposed when ordering. If there are any errors, please contact the supplier immediately. 2. Before installation, you should read the instruction manual carefully and check whether the actual working condition parameters on site are within the usage range of the product you purchased. If the working condition parameters on site exceed the allowed range, please stop installation or use immediately and consult us to avoid accidents. or damage the product. 3. Strictly follow the installation steps, remember the precautions and key points, and make full preparations before installation. 4. Before installing and connecting the solenoid valve to the pipeline, flush the pipeline with air or water ≥0.3MPa to ensure that impurities (such as welding slag, sealing residue, dirt, etc.) in the pipeline are removed before connecting the solenoid valve. 5. The solenoid valve should not be installed in a low recess of the pipeline. If it is installed in the discharge pipeline section of the container, the pipeline outlet should not be led from the bottom of the container to prevent impurities deposited at the bottom of the container from rushing out and entering the solenoid valve to cause failure. Therefore, the pipeline outlet should be from Lead out slightly above the bottom of the container. 6. Solenoid valves can generally only be used in one direction and cannot be installed backwards. Usually there is a "" mark on the valve body to indicate the flow direction of the medium, or the English letters "IN" indicates the inlet and "OUT" indicates the outlet. Please be sure to follow this direction. installation, otherwise it will automatically open or leak when the fluid reaches the solenoid valve. 7. When taking over the pipe, be careful not to use too much sealing material. For example, when connecting with threads, the length of the external thread of the pipe should not exceed the effective length of the internal thread of the solenoid valve. Use a file to chamfer the half pitch of the front end of the external thread and start winding from the 2nd thread. Sealing tape, otherwise excessive sealing tape or adhesive residue entering the inner cavity of the solenoid valve will cause malfunction. 8. Requirements for the fluid of the solenoid valve: It should be ensured that the fluid has no impurities, no crystallization, no solidification, no scale, no paste, and a viscosity of <22CST, otherwise it will cause failure. At the same time, a filter should be installed on the front end pipe of the solenoid valve. , and the mesh number of the filter should be ≥60 mesh to prevent impurities from entering the solenoid valve. 9. Pay attention to the protection level of the product you ordered. The ordinary type cannot be used in flammable and explosive hazardous situations. The IP54 level should not be installed in the open air, in places with severe water leakage or splashing water. 10. The solenoid valve should be installed in a horizontal pipeline (as shown in Figure 1). The coil should be vertically upward and not installed vertically (as shown in Figure 2), otherwise it will cause leakage and affect the service life. 11. The installation position of the solenoid valve should reserve a certain operating space to facilitate daily maintenance and regular maintenance. 12. When the pipe rigidity is insufficient or there is water hammer, it is recommended to fix the pipes before and after the valve with brackets or other methods to prevent vibration caused by the solenoid valve during operation. 13. When used in freezing or cold places, the pipes and valve body must be insulated with insulation materials or a heater must be installed on the pipes. 14. After the solenoid valve and the pipeline are connected, press forward (do not press in the reverse direction, otherwise the solenoid valve will be damaged), and check whether there is leakage at the solenoid valve and the pipe. 15. For solenoid valves equipped with a standard junction box, the plastic junction box should be removed and opened. The factory test power cord should be removed and the user power cord should be connected to the terminal and fixed. However, for wire or lead type solenoid valves, it cannot be removed. , connect the wire directly to the user's power cord. 16. The power control circuits and facilities related to the solenoid valve, such as relays, switches and contactors, should be firmly connected and should not be loose or vibrating. The electrical circuit should be connected to the corresponding insurance wire as a protection for the electrical circuit, otherwise it will affect the electrical circuit. The solenoid valve is working properly or is damaged. 17. In order to facilitate normal maintenance or prevent repair and replacement when the solenoid valve fails, and ensure the normal operation of the system, it is recommended to adopt one of the following backup pipeline solutions: 18. After the solenoid valve is installed and the preliminary preparation and test procedures are completed, it must be Test the fluid inlet 3 to 5 times, and then put it into formal use after confirming that it is normal. 19. Note: If you tell us that the solenoid valve is passed through liquid when you order it, but it is passed through gas during the test, if leakage occurs or the leakage exceeds the standard, it is a normal phenomenon, because there are differences in density and viscosity between gas and liquid. At this time, if When you pass in liquid, there will be no leakage or excess. The above is how to install the solenoid valve and the correct installation content of the solenoid valve.
