The vacuum plasma circuit control valve commonly used by Chengfeng Zhizhi vacuum plasma cleaning machine brand:
In the vacuum plasma cleaner, the gas path control mainly includes two parts: process gas control and vacuum path control. Let's take a look at the control valves used to control the vacuum plasma circuit of the Fengzhi vacuum plasma cleaner brand. Air path control is a key link in the vacuum plasma cleaning machine, which mainly includes process gas control and vacuum path control. In the control part of the vacuum circuit, the commonly used control valves include high vacuum pneumatic baffle valves, manual high vacuum angle valves, and electromagnetic vacuum with inflation valves. Chengfeng Zhizhuang vacuum plasma cleaning machine brand introduces these three controls in detail for you valve.
High vacuum pneumatic baffle valve (GDQ):

Generally, when the vacuum plasma cleaner is in the standby state, the vacuum pump will remain in the vacuum state, and the high-vacuum pneumatic baffle valve is used to turn on or cut off the air flow in the vacuum pipeline, so that the vacuum chamber is started and closed.
Compressed air is used as the power unit of the high-vacuum pneumatic baffle, which is stable and reliable, easy to maintain, and widely used in vacuum plasma cleaners.
Electromagnetic vacuum belt charging valve (DDC):
The electromagnetic vacuum charging valve is used in the vacuum plasma cleaning machine that the vacuum pump starts with the operating parameters, and belongs to the solenoid valve type. When the vacuum pump is running, the electromagnetic vacuum belt inflation valve is opened, when the vacuum pump is closed, the valve coil is cut off, and the valve is closed by mechanical force. Its main function is to prevent the oil and gas in the vacuum chamber from being sucked back due to the negative pressure inside the vacuum pump.
The electromagnetic vacuum charging valve is simple to install, but its stability is poor. After long-term use, the magnetism of the valve will attenuate, and the return spring is prone to slow response. At present, it is mostly used in experimental vacuum plasma cleaners.
Manual high vacuum angle valve:.
The manual high vacuum angle valve used in the vacuum plasma cleaner is generally custom-made, and is mainly used to manually control the on-off and pressure-off of the vacuum circuit. The KF16 connector is usually welded on the angle valve to connect the vacuum gauge.
This valve is rarely used for vacuum plasma cleaning, and is mainly used for leak detection of some experimental equipment and vacuum pipelines.
