[0026] Preferably, a power supply assembly consisting of a battery pack 29 and a conductive sheet 30 is provided in the clip-type compartment cover 2 .

[0027] Preferably, a spring 31 electrically connected to the conductive sheet 30 is provided on the circuit board 21 .

[0032] The working principle of the pipeline gas timing valve: The pipeline gas timing valve is powered by the battery pack 29 of the power supply component. When the circuit board 21 is energized, the control module on the circuit board 21 discharges the electromagnetic coil 8 in the forward and reverse directions to realize the automatic opening and closing of the timing valve. When the electromagnetic coil 8 receives the forward and reverse discharge, it can control the left and right movement of the steel ball 11 in the pipe 7 to realize the automatic opening and closing of the valve. The sensing diaphragm is used to sense changes in gas pressure and test unsafe conditions such as overpressure, underpressure and overcurrent. Specifically: 1. When overpressure occurs in the open valve state, the sensing diaphragm opens, the valve stem 19 drives the conduction plate 20 to rise and contact the upper contact seat 22. The control module of the circuit board 21 collects the corresponding status and releases an electrical signal to the electromagnetic coil 8. The steel ball 11 moves toward the valve seat 14 and closes the valve port. At the same time, the overpressure status is fed back to the controller. 2. When undervoltage or overcurrent occurs in the valve open state, the sensing diaphragm contracts. Under the action of the spring 18, the valve stem 19 drives the conduction plate 20 to descend and contact the lower contact seat 23. The control module of the circuit board 21 collects the corresponding status and releases an electrical signal to the electromagnetic coil 8. The steel ball 11 moves toward the valve seat 14 and closes the valve. At the same time, the undervoltage and overcurrent status are fed back to the controller. 3. When the valve is closed and the pressure is maintained, the sensing diaphragm senses the under-pressure condition, the conduction plate 20 drops, triggering the lower contact seat 23, and the control module of the circuit board 21 senses and feeds back the under-pressure and leakage conditions to the controller.

[0033] In addition, when the controller fails, the timed self-closing valve itself can also open and close automatically.

[0034] Functional description of the controller: 1. Timing function: After the timing, the safety valve will automatically open, and when the time is up, the safety valve will automatically close; 2. Time setting function: The time length is adjustable, the normal setting is 60 minutes, and the time adjustment knob 26 can be used to adjust the time length from 5 to 180 minutes; 3. It has the function of starting the valve with one button and can also automatically close the valve; 4. Low battery alarm function: can remind the low battery of timing valve and controller respectively; 5. With overpressure, underpressure, overcurrent, leakage and normal indication functions; 6. It has sound and light alarm function to warn users.

[0035] Controller working principle: The display screen 28 is always in the bright screen state, and the safety valve is started with one button, and the valve opening time is automatically set to 60 minutes. The length of time can be adjusted by turning the time adjustment knob 26. The time is adjustable from 5 to 180 minutes. Rotate it clockwise to lengthen it, and rotate it counterclockwise to shorten it. During the gas use process of the timing valve, when the timing valve senses overpressure, underpressure, overcurrent or leakage, the timing self-closing valve automatically closes and gives a feedback signal to the controller. The controller displays the corresponding unsafe state and emits a buzzer to alarm. The alarm signal needs to be manually checked and the button can be released. The release method is to press and hold the button 278S.
