The vacuum magnetic valve is a special valve for vacuum installed on the mechanical vacuum pump. The valve and the pump are connected to the same power supply, and the opening and stopping of the pump directly controls the opening and closing of the valve. How to use vacuum magnetic valve in vacuum system?

　　The vacuum magnetic valve is connected to the same power supply as the pump, and the opening and stopping of the pump directly controls the opening and closing of the valve. When the pump stops working or the power supply is suddenly interrupted, the valve can automatically close the vacuum system, and fill the air into the pump cavity through the air inlet of the pump, so as to avoid the backflow of pump oil from polluting the vacuum system.

　　The working medium suitable for vacuum magnetic valve is air and non-corrosive gas. How to use the vacuum magnetic valve in the vacuum system mainly includes the following points:

　　1. Before installing the vacuum magnetic valve, you should read the instruction manual of the product carefully, check whether the product fully meets the requirements for use, be familiar with the installation points, and make preparations.

　　2. When installing, the coil of the vacuum magnetic valve should be upward and keep the vertical position. The arrow or mark on the ZCA vacuum magnetic valve should be consistent with the flow direction of the pipeline, and it should not be installed in a place with splashing or leaking water.

　　3. Ordinary vacuum magnetic valves cannot be used in flammable and explosive hazardous situations.

　　4. When the vacuum magnetic valve fails, in order to isolate the ZCA vacuum magnetic valve in time and ensure the normal operation of the system, it is best to install a bypass device.

　　5. Do not install the vacuum magnetic valve in the low recess of the pipeline, so as to avoid steam condensed water, impurities and other deposits in the valve and hinder the operation.

　　6. When the rigidity of the pipeline is insufficient, it is recommended to fix the front and rear pipes of the vacuum magnetic valve with brackets to prevent the ZCA vacuum magnetic valve from causing vibration when it is working.
