Electrojet air control solenoid valve? Water temperature vacuum valve action

Vacuum valve refers to the valve whose working pressure is lower than the standard atmospheric pressure.

Vacuum valve refers to the components used to change the direction of air flow, adjust air flow and cut off or connect pipes in vacuum system. The closing part of vacuum valve is sealed with rubber sealing ring or metal sealing ring.

1, switch the gas path. As shown in the following figure: When valve 1 and valve 4 are closed and valve 2 is opened, mechanical vacuum pump III vacuumizes container I, and air flows through the pre-vacuumized exhaust pipe; When the valve 2 is closed and the valve 4 is open, the mechanical pump can pump the vacuum diffusion pump alone; When valve 1 and valve 4 are opened at the same time, the diffusion pump and mechanical pump can work at the same time to vacuum the container, and air flows through the diffusion pump at this time. It can be seen that the function of the valve in this operation is to switch the gas path and change the flow route of the gas flow.

2. control the airflow. Adjust the vacuum degree in the figure, and adjust the opening angle of the valve cover 1 to adjust the air flow through the pipeline; Close the valve 2 and the valve 4, and the inlet of the mechanical pump III can be exhausted to the atmosphere through the exhaust valve 3; The vacuum degree in the container can be adjusted by the air release valve 5. 3, quantitative expansion. There is a small hole with a certain volume on the plunger of the glass valve. When the small hole rotates to the right and communicates with the high-pressure gas cylinder, the small hole can be filled with high-pressure gas. When it rotates to the left and communicates with the vacuum container, this volume of high-pressure gas is put into the container, thus playing the role of quantitative inflation.
