The monitoring part 101 can be an existing turbine flowmeter, the vortex flowmeter generally comprises an impeller, a magnetoelectric converter and the like, when fluid passes through the channel 100, the impeller rotates under stress, the magnetoelectric converter converts the rotating speed of the impeller to obtain fluid parameters, the control component receives fluid parameter signals and then judges the fluid parameter signals, and then corresponding on-off signals are sent to the coil 301 of the electromagnet part 3. If the fluid parameter reaches the set value, i.e. the coil 301 is supplied with current in the response direction, the magnetic field force generated by the coil 301 drives the sliding rod 300 to move, and the sealing plate 302 follows the movement to close the valve body 2, thereby interrupting the fluid delivery.

Specifically, the household water is used as a use scene for description, if the control assembly presets the continuous water use time of a common household for 30 minutes as a normal state, the fluid monitoring part 1 starts timing when the water flowing in the pipeline is monitored, if the duration time of the fluid flowing is monitored to be less than the preset 30 minutes, the household water is considered as normal water use, if the flowing time is monitored to be greater than the preset time, the household water is judged to be abnormal (a water pipe bursts, a water tap is forgotten to be closed, and the like), at the moment, the control assembly sends a signal to the electromagnet part 3 after judgment, the current in the coil 301 pushes the sliding rod 300 downwards by generating a corresponding magnetic field acting force, so that the sealing sheet 302 closes. When the valve body 2 needs to be restored, the control assembly can be manually operated to send a signal, the coil 301 generates current in a corresponding direction, and the sliding rod 300 is retracted through the action force of the magnetic field to open the valve body 2. Referring to fig. 4, the chip model of the control assembly can adopt 89C2051, and a power supply J1 part, a turbine flowmeter J2 part and a solenoid coil J3 part for outputting forward and reverse voltages are connected to corresponding pins.
