[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 5 As shown, a quick cut-off valve for gas includes a cut-off valve body 1. A power supply placement box 2 is provided on the cut-off valve body. A moving plate 3 is slidably clamped inside the power supply placement box 2. An automatic changeover switch is installed on the power supply placement box 2. A backup power supply 4 is clamped on the moving plate 3 of the automatic changeover switch. The backup power supply 4 is connected with a converter. Through the converter, the output voltage of the backup power supply 4 is the same as that of the power supply connected to the electrolysis. The output end after conversion of the backup power supply 4 is electrically connected to the driving component 8. The automatic changeover switch automatically detects the state during power failure and automatically connects the output end after conversion of the backup power supply 4 to the driving component 8, which can ensure the use of the present invention under power failure. A connection hole 5 is opened inside the cut-off valve body 1, and a sealing plug 6 is plugged inside the connection hole 5. An installation box 7 is provided on the cut-off valve body 1. A driving component 8 for driving the sealing plug 6 is provided on the installation box 7. Through the driving component 8, the position of the sealing plug 6 can be flexibly adjusted, thereby facilitating the opening or closing of the connection hole 5. A power supply ejection component 9 is provided inside the power supply placement box 2. Through the power supply ejection component 9, the moving plate 3 can be ejected, thereby facilitating the replacement of the backup power supply 4.

[0021] The driving component 8 includes a mounting block 801 and a moving rod 802. The mounting block 801 is fixedly installed on the surface of the mounting box 7. The moving rod 802 is fixedly connected to the sealing plug 6. A toothed plate 803 is installed on the moving rod 802, and a rotating gear 804 is engaged with the toothed plate 803. A motor 805 is installed on the mounting block 801. The input end of the motor 805 is connected to the output end after conversion of the backup power supply 4. The automatic switching switch automatically detects the state during power failure and automatically connects the output end after conversion of the backup power supply 4 to the motor 805, which can ensure the use of the present utility model under the condition of power failure and improve the applicability of the present utility model. The output end of the motor 805 is fixedly connected to the rotating gear 804. By rotating the motor 805, the rotating gear 804 is driven to rotate, the toothed plate 803 moves, and the moving rod 802 moves, so as to adjust the position of the sealing plug 6 and facilitate opening or closing the connection hole 5. A sealing block 10 is installed inside the mounting box 7, and the sealing block 10 is inserted into the moving rod 802, which is convenient for increasing the sealing performance of the present utility model through the sealing block 10.

[0022] One end of the moving plate 3 is of a hollow structure, and a clamping hole 11 is opened at one end of the moving plate 3. The mounting plate 901 is fixedly installed inside the power supply placement box 2. The inside of the mounting plate 901 is of a hollow structure, and a button 902 is inserted into the inside of the mounting plate 901. The button 902 is inserted into the power supply placement box 2. A first spring 903 is fixedly installed inside the button 902, and the other end of the first spring 903 is fixedly connected to the inner wall of the mounting plate 901. A clamping rod 904 is fixedly installed on one side of the button 902, and the clamping rod 904 is clamped with the clamping hole 11. Inside the mounting plate 901 and on both sides of the button 902, second springs 905 are fixedly installed, and a pop-up block 906 is fixedly installed at the other end of the second springs 905. The state of the second springs 905 is a compressed state. When the button 902 is pressed, the first spring 903 is compressed, the clamping rod 904 moves, so that the clamping rod 904 is separated from the moving plate 3. Under the action of the elastic restoring force of the second springs 905, the moving plate 3 pops out, which is convenient for manually pulling the moving plate 3 to replace the backup power supply 4. The pop-up block 906 is inserted into the mounting plate 901, one end of the pop-up block 906 is in contact with the moving plate 3, and a cover plate 12 is fixedly installed at the upper end of the moving plate 3. The cover plate 12 is clamped with the power supply placement box 2.

[0023] When the present utility model is in use and needs to be opened or closed, the motor 805 is started to drive the rotating gear 804 to rotate. The toothed plate 803 moves, and the moving rod 802 moves, thereby adjusting the position of the sealing plug 6 to open or close the connection hole 5. The sealing block 10 facilitates increasing the sealing performance of the present utility model. When it is necessary to replace the backup power supply 4, the button 902 is pressed, the first spring 903 is compressed, and the clamping rod 904 moves, causing the clamping rod 904 to separate from the moving plate 3. Under the action of the elastic restoring force of the second spring 905, the moving plate 3 pops out, and then it is convenient to manually pull the moving plate 3 to replace the backup power supply 4. After the replacement is completed, the button 902 is pressed, the moving plate 3 is moved, the ejecting block 906 moves, the second spring 905 is compressed, and the clamping rod 904 is inserted into the clamping hole 11. The force applied to the button 902 is cancelled, and under the action of the elastic restoring force of the second spring 905, the clamping rod 904 is clamped with the clamping hole 11. When the automatic changeover switch automatically detects the power-off state, the output end after the conversion of the backup power supply 4 is automatically connected to the motor 805, which can ensure the use of the present utility model in the case of power failure.
