Vacuum magnetic valve in china is a quick cut-off valve. When the working pressure is lower than the normal standard atmospheric pressure, it forms a certain vacuum (negative pressure) solenoid valve. It is suitable for vacuum equipment pipelines and is a commonly used valve for switching two positions,when the equipment is closed, the outlet can be quickly closed to prevent accidents caused by reverse suction and form a high vacuum environment.

　　Vacuum magnetic valve in china is composed of screw plug, spring, shell, bushing, left and right valve seats, valve stem combination, ejector rod, electromagnet and armature, etc. According to different structural forms and control methods, vacuum solenoid valves can usually be divided into three types: pressure-holding type, exhaust type and two-way pressure-holding type.

　　Vacuum magnetic valve in china controls the opening and closing through AC or DC power supply, and can use the electromagnetic principle to realize vacuum treatment on the pipeline. It is mainly used in the vacuum pipeline or the linkage control system with the vacuum pump. It is directly operated by the electromagnet to control the opening and closing of the valve to connect the atmosphere to break the air and to fill the vacuum container with the atmosphere, so as to achieve automatic control or remote control.

　　At the same time, electromagnetic control is realized, and the Vacuum magnetic valve in China can have a greater impact on the entire working state of the pipeline system, and the use of vacuum solenoid valves can also effectively avoid the influence of other irrelevant factors on the pipeline, thereby affecting the pipeline system. Make correct adjustments to the working status.
