Vacuum solenoid valve has such a strong regulation and control role, so in life, pipeline transportation is still widely used. In petrochemical industry, the application of vacuum solenoid valve makes oil transportation pipeline and natural gas pipeline more effective. In addition to being used in industrial fields, vacuum solenoid valves are also used in urban heating and water supply projects. Next, I will introduce the faults of vacuum solenoid valve and precautions for vacuum solenoid valve installation

vacuum solenoid valve has such a strong regulation and control function, so it is widely used in pipeline transportation in life. In petrochemical industry, the application of vacuum solenoid valve makes oil transportation pipeline and natural gas pipeline more effective. In addition to being used in industrial fields, vacuum solenoid valves are also used in urban heating and water supply projects. Next, I will introduce the faults of vacuum solenoid valve and precautions for vacuum solenoid valve installation

vacuum solenoid valve failure

according to relevant personnel, when the pump suddenly stops working or the power supply is suddenly interrupted, the valve will automatically close the vacuum system, and then directly fill the atmosphere into the pump cavity through the air inlet of the pump, thus avoiding the phenomenon of pump oil backflow and polluting the vacuum system. In general, the working medium for vacuum solenoid valves is our usual air and some gases that have not been corroded

mention the situation that this solenoid valve cannot be closed normally. The seal of the main valve core or the iron core has been damaged. We need to replace the seal. The liquid temperature and viscosity are also too high. Then consider whether to change the corresponding solenoid valve. If there are impurities entering the solenoid valve core or iron core, it is necessary to pay attention to cleaning at this time

principle of vacuum solenoid valve

the main working principle of vacuum solenoid valve is to use electromagnetic induction phenomenon to control the pipeline by electromagnetic induction, and also to use vacuum principle to make a vacuum structure inside the valve, which can effectively improve the working efficiency of vacuum solenoid valve and make it a device that can control the pipeline efficiently. When the medium in the pipeline, whether liquid or gas, passes through the pipeline near the vacuum solenoid valve, the medium will send information to the induction device of the vacuum solenoid valve. Of course, the interior of the vacuum solenoid valve is vacuum, so the induction information is generally not disturbed by other factors. When the induction device transmits the electromagnetic signal, the valve will adjust the flow rate of the medium in the pipeline through the information, which is very efficient

precautions for installation of vacuum solenoid valve

1. During installation, pay attention to that the arrow on the valve body should be consistent with the flow direction of the medium. Do not install it where there is direct dripping or splashing. The solenoid valve should be installed vertically upwards

2. The solenoid valve shall ensure normal operation within the fluctuation range of 15%-10% of the rated voltage

3. After the solenoid valve is installed, there shall be no reverse differential pressure 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. Thoroughly clean the pipeline before installing the solenoid valve. The medium should be free of impurities. A filter is installed in front of the valve

5. When the solenoid valve fails or is cleaned, a bypass device should be installed to ensure the continuous operation of the system

editor's summary: that's all for the vacuum solenoid valve fault and precautions for vacuum solenoid valve installation. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
