[0002] Currently, with the widespread use of natural gas, gas safety is a social issue that cannot be ignored. The frequent gas safety accidents in recent years have also served as a constant wake-up call for us.

[0003] However, current piped gas self-closing valves have many shortcomings in practical applications:

[0004] 1. Currently, the automatic shut-off valve for piped gas cannot detect and close when there is a slight leak in the downstream hose and gas pipeline;

[0005] 2. Currently, the automatic shut-off valve for piped gas remains open both when gas is in use and when gas is not in use, posing a safety risk.

[0006] 3. Currently, due to its own structural limitations, the installation location of the automatic shut-off valve for piped gas is restricted, making it difficult for users to observe the opening and closing status of the valve.

[0007] 4. Currently, although the automatic shut-off valve of piped gas will automatically close when it detects unsafe conditions such as overpressure, underpressure or overcurrent, it cannot issue a warning message to alert the user.

[0008] 5. Users cannot quickly and intuitively understand the reason for the closure of the pipeline gas automatic shut-off valve, making subsequent troubleshooting and maintenance difficult. Summary of the Invention

[0009] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an intrinsically safe intelligent pipeline gas timer valve and its associated controller, which solves the current shortcomings of pipeline gas self-closing valves.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the intrinsically safe intelligent pipeline gas timer valve and its controller are described. The pipeline gas timer valve includes a housing 1 and a clip-on cover 2 mounted on the housing 1. The clip-on cover 2 is mounted on the housing 1 by a snap-fit ​​method, and the clip-on cover 2 has anti-slip textures on both sides for easy disassembly.

A circuit board 21 is also provided inside the outer casing 1. The circuit board 21 has an upper contact seat 22 and a lower contact seat 23 located above and below the conductive plate 20, respectively. The coil encapsulation body 6 has a pin 24 that connects to the circuit board 21.

[0037] To elaborate further, the controller includes a housing 25 and a time adjustment knob 26 located outside the housing 25. Inside the housing 25, there is a transmission structure, such as a gear transmission assembly, that is linked to the time adjustment knob 26. The time adjustment knob 26 is mainly used to adjust the timing duration. The housing 25 has a button 27. The back of the housing 25 adopts a magnetic structure. The housing 25 has a display screen 28 that displays the valve opening / closing status, set time, overpressure indicator, underpressure indicator, overcurrent indicator, leakage indicator, controller low battery reminder, and timer self-closing valve low battery reminder. The controller also has a power supply device. The controller is wirelessly connected to the gas timer valve via Bluetooth. The controller has a magnetic sticker and a metal plate with adhesive backing, which can be easily attached to any safe location that is easy to operate and observe.

[0038] Preferably, the magazine-type compartment cover 2 is provided with a power supply assembly consisting of a battery pack 29 and a conductive sheet 30, and the circuit board 21 is provided with a spring piece 31 that is electrically connected to the conductive sheet 30.

[0039] Preferably, the valve body 3 has a channel 32 that communicates with the interior of the valve cover 15.

[0040] To elaborate further, the air inlet 4 is equipped with a union nut 33 connected to the pipe 7. The union nut 33 is equipped with a connecting nut 34 that connects to the gas pipeline, and a sealing gasket 35 is provided between the connecting nut 34 and the union nut 33. Acrylic plates 36 are installed on both sides of the outer casing 1, and control buttons 37 and indicator lights 38 are provided on both acrylic plates 36.

In addition, in order to be suitable for installation with different pipeline routes, control buttons 37 and indicator lights 38 with the same structure and function are provided on both sides of the outer casing 1. The gas source on both sides of the timer valve can be either left inlet and right outlet or left outlet and right inlet, which is not limited to the installation method of this product, and facilitates Bluetooth wireless pairing and emergency use.

[0041] Preferably, the end face of the guide frame 12 has a cross-section 39 that provides guidance for the steel ball 11.

[0042] Preferably, the conductive plate 20 is mounted on the valve stem 19 by screws, and the conductive sheet 30 floats between the upper contact seat 22 and the lower contact seat 23 due to the tension change of the pressure-sensitive diaphragm 16.

[0043] The working principle of this pipeline gas timing valve:

[0044] The timer valve for piped gas is powered by the battery pack 29 of the power supply component. When the circuit board 21 is powered on, the control module on the circuit board 21 discharges to the electromagnetic coil 8 in the forward and reverse directions to realize the automatic opening and closing of the timer valve. When the electromagnetic coil 8 receives the forward and reverse discharge, it can control the steel ball 11 in the pipe 7 to move left and right to realize the automatic opening and closing of the valve.

[0045] The sensing diaphragm is used to sense changes in gas pressure and to detect unsafe conditions such as overpressure, underpressure, and overcurrent. Specifically:

[0046] 1. When an 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 state, releases an electrical signal to the electromagnetic coil 8, the steel ball 11 moves towards the valve seat 14 and closes the valve, and at the same time feeds back the overpressure state to the controller.

[0047] 2. When undervoltage or overcurrent occurs in the open valve state, the sensing diaphragm contracts. Under the action of spring 18, valve stem 19 drives the conduction plate 20 to descend and contact the lower contact seat 23. The control module of circuit board 21 collects the corresponding status, releases an electrical signal to electromagnetic coil 8, and steel ball 11 moves towards valve seat 14 and closes the valve. At the same time, the undervoltage and overcurrent status is fed back to the controller.

[0048] 3. When the valve is closed and pressure is maintained, the sensing diaphragm detects the undervoltage condition, the conduction plate 20 descends, triggering the lower contact seat 23, and the control module of the circuit board 21 senses and feeds back the undervoltage and leakage status to the controller.

[0049] In addition, the timed self-closing valve can also automatically open and close when the controller malfunctions.

[0050] Functional description of the controller:

[0051] 1. Timer function: After the timer is set, the safety valve will automatically open and automatically close after the time is up.

[0052] 2. Time setting function: The duration is adjustable. The normal setting is 60 minutes, and it can be adjusted from 5 to 180 minutes using the time adjustment knob 26.

[0053] 3. It has a one-button valve start function and can also automatically close the valve;

[0054] 4. Low battery alarm function: can separately alert the timer valve and controller to low battery levels;

[0055] 5. It has overvoltage, undervoltage, overcurrent, leakage, and normal indication functions;

[0056] 6. It has an audible and visual alarm function to alert users.

[0057] Controller working principle:

[0058] The display screen 28 remains on. A one-button start safety valve automatically sets the opening time to 60 minutes, which can be adjusted by rotating the time adjustment knob 26 from 5 to 180 minutes. Clockwise rotation lengthens the time, while counter-clockwise rotation shortens it. During gas usage, if the timer valve senses overpressure, underpressure, overcurrent, or leakage, the timer self-closing valve automatically closes and sends a feedback signal to the controller. The controller displays the corresponding unsafe condition and sounds an alarm. The alarm signal requires manual investigation and button operation to deactivate; the deactivation method is to press and hold button 278 for 8 seconds.
