The bottom features of vacuum valve are high air tightness (firm sealing); the resistance to air flow is as small as possible (i.e. the flow of the valve is fully conducted or large); the wear resistance of the sealing parts is good, which can be reused and has a long life; the valve body information and the amount of gas released from the sealing parts are small; the operation is flexible, simple, and the equipment is easy to clean. In addition, the function is reliable and the repair is convenient. On the ultra-high vacuum valve also required to be able to withstand high temperature baking (450 ℃); for the saving valve, it is required to regulate the gas flow evenly.
Materials of commonly used vacuum valve bodies are metal and glass. Manual vacuum valve driving handwheel is made of high-strength plastics. Glass vacuum piston, also known as "cork", is generally used in glass vacuum system, small vacuum equipment, vacuum gauge regulation or calibration system. The advantages are simple production, convenient operation, easy cleaning and investigation, good chemical stability and insulation, and less outgassing. The vacuum equipment required by industrial production, such as vacuum coating equipment, vacuum exercise equipment, vacuum heat treatment equipment, space environment simulation equipment, rocket engine simulation equipment, satellite surface charged simulation equipment, particle accelerator and controlled nuclear fusion equipment, heavy duty vacuum equipment are required for industrial production Metal valves are used in particle accelerators.
