[0021] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Reference Figure 1-4 , an embodiment of the utility model is proposed, a gas valve, including a valve body 1, a valve core 4 is rotatably provided inside the valve body 1, a connecting cylinder 13 is provided at the front end of the valve core 4, a valve needle 5 is provided inside the connecting cylinder 13, the rear end of the valve core 4 is a hollow structure forming an air dividing cavity 16 inside, and a through opening 15 communicating with the connecting cylinder 13 is opened at the front end of the inner wall of the air dividing cavity 16;

[0023] The surface of the valve core 4 is provided with a first opening 8 and a second opening 9 which are connected to the inner cavity of the air dividing cavity 16. The surface of the valve core 4 is provided with a delivery port 7 which is connected to the inner cavity of the connecting cylinder 13. The outer ends of the delivery port 7 are arranged in a T-shape with the first opening and the second opening 9.

[0024] The rear end of the top of the valve body 1 is connected to a first delivery channel 10 connected to the first opening 8 or the second opening 9, and the rear end of the side wall of the valve body 1 is connected to a second delivery channel 11 which can be connected to the delivery port 7. The bottom of the valve body 1 is fixedly connected to the valve seat 3, and the bottom of the valve seat 3 is provided with an air inlet channel 6 that is connected to the inner cavity of the valve body 1 to supply air to the air distribution cavity 16.

[0025] The valve body 1 is provided with a transmission member adapted to the solenoid valve, which is used to drive the transmission member to move and trigger the solenoid valve to work when the valve stem 2 moves. The solenoid valve and the transmission member are existing technologies and will not be described in detail here.

[0026] A valve stem 2 is provided on the front end face of the valve body 1 , and the rear end of the valve stem 2 is pulled out and extended to the inner cavity of the valve core 4 . A spring 19 is provided between the front end of the valve needle 5 and the rear end of the valve stem 2 .

[0027] By twisting the valve stem 2, the valve core 4 can be driven to rotate. After the second opening 9 is driven by the valve core 4 to rotate to the corresponding position of the air inlet channel 6, the first opening 8 is rotated to the corresponding position of the first delivery channel 10. Through the air inlet channel 6 and the second opening 9, gas can be injected into the inner cavity of the gas separation cavity 16. Through the guidance of the first opening 8, the gas can enter the inner cavity of the first delivery channel 10, and then through the connection of the through port 15, the gas enters the inner cavity of the gas separation cavity 13, and then through the guidance of the delivery port 7, the gas can enter the inner cavity of the second delivery channel 11.

The even distribution of gas ensures the high efficiency of energy during transmission and utilization, reduces gas loss, improves the overall gas utilization efficiency, and is conducive to improving cooking effects.

[0029] When it is necessary to close the second delivery channel 11 and use the first delivery channel 10 for independent air supply, the valve core 4 can be twisted to drive the first opening 8 to move to the corresponding position of the air inlet channel 6. After the second opening 9 moves to the corresponding position of the first delivery channel 10, the delivery port 7 and the second delivery channel 11 are staggered and conflict with the wall of the valve core 4, so that 10 can be used for independent air supply.

[0030] When closing is required, the valve core 4 is twisted to move the closed portion of the valve core 4 surface to a position corresponding to the air inlet passage 6, thereby cutting off the supply of gas and completing the closing operation.

[0031] Furthermore, external threads 12 are provided on the top ends of the surfaces of the first conveying channel 10 and the second conveying channel 11. The external threads 12 facilitate the connection between the first conveying channel 10 and the second conveying channel 11 and the connecting pipe.

[0033] During the movement of the valve stem 2 , the slider 17 is driven to slide in the inner portion of the slide groove 18 , thereby improving the stability of the valve body 1 during the movement. Furthermore, during the rotation of the valve stem 2 , the valve core 4 can be driven to rotate.

[0034] Furthermore, a plurality of mounting holes are provided on the surface of the valve seat 3 , and the plurality of mounting holes facilitate the fixing of the valve stem 2 and the installation and use of the valve body 1 .

[0035] Furthermore, a sealing member 14 is fixedly connected to the surface of the valve needle 5 and contacts the inner wall surface of the valve core 4 .

[0036] The sealing member 14 seals between the valve needle 5 and the valve core 4 , thereby improving the airtightness of the inner cavity of the gas dividing cavity 13 , preventing gas leakage, and improving the stability of the gas entering the delivery port 7 through the inner cavity of the gas dividing cavity 13 .

[0037] During operation, twisting the valve stem 2 can drive the valve core 4 to rotate. After the valve core 4 drives the second opening 9 to rotate to the corresponding position of the air inlet channel 6, the first opening 8 rotates to the corresponding position of the first delivery channel 10, and the gas can be injected into the inner cavity of the gas separation chamber 16 through the air inlet channel 6 and the second opening 9. The gas can enter the inner cavity of the first delivery channel 10 through the guidance of the first opening 8, and then enter the inner cavity of the gas separation chamber 13 through the connection of the through port 15. Then, the gas can enter the inner cavity of the gas separation chamber 13 through the guidance of the delivery port 7, and enter the inner cavity of the second delivery channel 11, and evenly distribute the gas in the inner cavities of the first delivery channel 10 and the second delivery channel 11. The uniform distribution of gas ensures the high efficiency of energy in the transmission and utilization process, reduces gas loss, improves the overall gas utilization efficiency, and helps to improve the cooking effect.
