(Summary description)Compressed gas is an essential part of modern industry. The common compressed gas in industry mainly includes compressed air (CDA) and bottled compressed gas. Compressed air is called the second power source, second only to electricity, and is a multi-purpose process gas source. Bottled compressed gas for industrial use is usually contained in a controlled cylinder with a pressure of 13-15 mpa. Its advantages are space-saving, safe and easy to transport. Compressed gas in the use of the actual use of demand for decompression and voltage regulation, so the plasma cleaning machine gas pressure regulation of what, and what are the use of skills? Gas pressure control is one of the important parameters to ensure the normal operation of plasma cleaning machine, common gas pressure reducer, pneumatic pressure regulating valve and pipeline throttle valve. 1. Cylinder pressure reducer: Cylinder unloader is a device for reducing the pressure of gas in a cylinder to the pressure of gas. The process gas used in the plasma cleaning machine is mostly bottled high-pressure gas. In order to ensure the process stability and the working stability of each gas circuit element, the high-pressure gas is usually reduced to 0.2-0.4mpa through the cylinder pressure reducer. It is necessary to ensure the sealing of the gas cylinder connecting the pressure-relief device and the pressure-relief device connecting the air pipe. When installing the pressure-relief device to the gas cylinder, the raw material belt shall be used as the sealing medium and wound on the threaded mouth of the gas cylinder. The output interface of the pressure-relief device is recommended to use the 3/8 standard interface, which is convenient to replace the original tower joint with quick twist joint or double sleeve joint, so as to ensure the sealing between the process gas output pipe and the gas interface of the plasma cleaning machine. If the industrial gas is argon, an oxygen pressure reducer is recommended. The main reason is that the output pressure of the special argon pressure-relief device is usually 0.15mpa. For example, one bottle of gas is supplied to two or more plasma cleaning machines, and the output pressure cannot meet the requirements of use, which is likely to cause undervoltage alarm of the device.   2. Pneumatic pressure regulating valve: Pneumatic pressure regulating valve is an important part of pneumatic control, its role is to control the external compressed gas at the required working pressure, and ensure its pressure and flow stability. Whether it is vacuum plasma cleaning machine or atmospheric plasma cleaning machine, pneumatic pressure regulating valve will be installed when the gas input, in order to ensure the cleanliness of the gas can be installed in the use of gas filter module. The following picture shows the application of pressure regulating valve and filter assembly in atmospheric plasma cleaning machine. To facilitate the inspection of gas pressure, pressure gauge can be installed on the pressure regulating valve or choose a pressure regulating valve with pressure gauge. If you need to provide undervoltage alarm, you can also choose the pressure gauge with alarm output function or add pressure switch. 3. Pipe throttle Valve: Pipeline throttle valve is usually used in atmospheric plasma cleaning machine, through its regulating needle valve to adjust the size of the vent to achieve pressure and flow control. Most of the common pipe throttle valves are quick plug joints, and the volume is relatively small. The process gas used by the atmospheric plasma cleaning machine is purified clean compressed air, and the pressure stability requirements are much lower than the vacuum plasma cleaning machine, so part of the atmospheric plasma cleaning machine directly installed in the air pipeline throttle valve to achieve pressure and flow control. Similarly, if the need for real-time pressure monitoring, can be installed on the gas line pressure gauge, with alarm output pressure gauge and pressure switch and other devices.
