How to connect the vacuum solenoid valve to air, installation methods and precautions of the vacuum solenoid valve

How to connect the vacuum solenoid valve to the gas control logic, there are two Y points, y1 lights up and there is vacuum in the suction nozzle, y2 lights up and there is no vacuum, y1 and y2 cannot light up at the same time. Control logic, two Y points, y2, actual connections: 1P is connected to the vacuum, No. 3 is connected to the vacuum outlet, No. 4 is blocked, the side They cannot light up at the same time. Vacuum solenoid valve installation method 1. When installing the vacuum solenoid valve, the coil is upward and kept in a vertical position. The arrow or mark on the vacuum solenoid valve should be consistent with the flow direction of the pipeline. The vacuum solenoid valve must not be installed in a place with splashing or leaking water. 2. The working medium of the vacuum solenoid valve should be clean and free of particle impurities. Dirt and filters on the surface of the vacuum solenoid valve's internal parts need to be cleaned regularly. 3. When the vacuum solenoid valve fails, in order to isolate the solenoid valve promptly and ensure the normal operation of the system, a bypass device should be installed. 4. In the pipeline system, the diameter of the vacuum solenoid valve installed on the branch line should be smaller than the diameter of the main pipeline valve. 5. Before installing the vacuum solenoid valve, the pipeline must be cleaned. It is recommended to install a filter in front of the valve and a trap in the steam pipe. 6. The vacuum solenoid valve cannot be installed in a recessed part of the pipeline to prevent steam condensation, impurities, etc. from settling in the valve and impeding its operation. 7. Vacuum solenoid valves cannot be used in explosive hazardous situations. 8. When the pipeline rigidity is insufficient, it is recommended to fix the pipeline in front of the valve with a bracket to avoid vibration caused by the vacuum solenoid valve during operation. 9. Before installing the vacuum solenoid valve, pay attention to the product label and read the instruction manual carefully to determine whether the product meets the conditions of use. 10. Pressure gauges need to be installed on the pipelines before and after the vacuum solenoid valve to facilitate observation of the pipelines. Precautions for installation of vacuum solenoid valve 1. When installing, please note that the arrow on the valve body should be consistent with the flow direction of the medium. Do not install in places with direct dripping or splashing water. The solenoid valve should be installed vertically upward. 2. The solenoid valve should ensure normal operation within the power supply voltage fluctuation range of 15%-10% of the rated voltage. 3. After the solenoid valve is installed, there must be no reverse pressure difference in the pipeline. And it needs to be powered on several times to make it suitable for temperature before it can be officially put into use. 4. The pipeline should be thoroughly cleaned before installing the solenoid valve. The incoming medium should be free of impurities. Install filter before valve. 5. When the solenoid valve fails or is cleaned, a bypass device should be installed to ensure that the system continues to operate. The above is an introduction to how to connect the vacuum solenoid valve to air, the installation method of the vacuum solenoid valve and the precautions.
