When the internal pressure leaks, the internal pressure becomes smaller and the second electrical contact does not contact the first electrical contact, and the signal is transmitted to the alarm sensor for alarm.

A valve tube 6 is penetrated through the top of the tube body 1, and a solenoid valve mechanism 7 is provided on the top of the valve tube 6. An anti-leakage mechanism 8 is provided on the outer wall of the solenoid valve mechanism 7 close to the connecting plate 2. The solenoid valve component inside the solenoid valve mechanism 7 is driven to work, and the connecting plates 2 and the sealing grooves 5 at both ends of the tube body 1 are cooperated to seal the inside of the tube body 1, and then the anti-leakage mechanism 8 is used to monitor whether the pressure in the sealed tube body 1 is leaked.

[0025] The sealing grooves 5 are all located between the inner walls of the connecting plate 2. The solenoid valve mechanism 7 is interconnected with the tube body 1 through the valve tube 6. The position of the sealing grooves 5 can indeed provide a good sealing effect. The solenoid valve mechanism 7 is interconnected with the inside of the tube body 1 to effectively control the flow of liquid or gas, thereby achieving the requirements of fluid control and playing a sealing role.

At the same time, the design of the valve stem 703 can also realize the control of the fluid, so that the flow of the fluid in different states can be accurately controlled. The overall structure is compact and the functions are complete, which is suitable for application in liquid or gas control systems and helps to improve the stability and reliability of the system.

[0027] The valve stem 703 is connected to the output end at the bottom of the solenoid valve 701, and the valve stem 703 penetrates the mechanical seal shaft 702.
