Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1 to 3 As shown, a gas valve component according to one embodiment of this utility model includes a valve body 1, which has a sealing groove 11, a first vent hole 12, and a first rotating groove 13. A first gas pipe 14 matching the first vent hole 12 is welded to the valve body 1. A sealing ball 2 is rotatably connected in the sealing groove 11. A second vent hole 21 matching the sealing groove 11 is formed on the sealing ball 2. A valve stem 22 matching the first rotating groove 13 is integrally formed on the sealing ball 2. When the valve stem 22 is rotated, the sealing ball 2 rotates in the sealing groove 11. When the second vent hole 21 and the sealing groove 11 form a passage, the gas valve component forms a passage, and the gas in the first gas pipe 14 can be passed to the gas stove.

[0028] To facilitate control of the valve stem 22 rotation, a foot pedal assembly for driving the valve stem 22 rotation is installed on the valve stem 22. The foot pedal assembly includes a retaining ring 23, which is sleeved on the valve stem 22. A pair of guide rails 24 are welded to the retaining ring 23, and a connecting bracket 27 is installed on the guide rails 24. A foot pedal 28 is welded to the end of the connecting bracket 27 away from the guide rails 24.

[0029] Specifically, when the chef needs to open the gas valve, they step on the foot pedal 28 located on the right side, causing the valve stem 22 to rotate clockwise. As the foot pedal 28 is repeatedly pressed down, the first vent 12 and the second vent 21 are connected, allowing gas to flow through the gas valve to the stovetop. Of course, by controlling the distance the foot pedal 28 moves, the rotation angle of the valve stem 22 can be controlled, thus controlling the opening size of the gas valve. This eliminates the need for manual operation when cooking.

[0030] If you need to close the air passage valve, step on the left foot pedal 28. The valve stem 22 will turn counterclockwise, and the second vent 21 will move away from the first vent 12, thus closing the air passage valve.

[0031] It is worth noting that when installing the gas valve, it should be installed close to the ground. Preferably, when the gas valve is in the closed state, the height between the left foot pedal 28 and the ground should be 5-8cm, which is convenient for the chef to control the opening and closing of the gas valve with their feet.

[0032] Furthermore, a leather cover 281 is fitted onto the foot pedal 28. The leather cover 281 is detachably fitted onto the foot pedal 28, providing an anti-slip function and facilitating removal and cleaning when there is a lot of oil residue after prolonged use.

[0033] It is worth noting that, since the pair of foot pedals 28 move in a circle around the valve stem 22, the distance between the pair of foot pedals 28 is large, and the footprint is large.

[0034] To solve the above problems, such as Figures 2 to 4 As shown, the air circuit valve also includes a fixing plate 3, on which a vertical groove 32 matching the connecting bracket 27 is provided, and the connecting bracket 27 passes through the vertical groove 32. A sliding groove 241 is provided on the guide rail 24, and a slider 25 is slidably connected in the sliding groove 241, and the connecting bracket 27 is rotatably connected to the slider 25.

[0035] Specifically, a fixed post 26 is welded onto the slider 25, and a second rotating groove 271 matching the fixed post 26 is provided on the connecting frame 27. When the foot pedal 28 is pressed down, the connecting frame 27 moves vertically downward in the vertical groove 32, and the connecting frame 27 rotates on the slider 25 via the fixed post 26. At the same time, the slider 25 slides in the sliding groove 241. This allows the foot pedal 28 to move linearly within the vertical groove 32, which not only shortens the distance between a pair of foot pedals 28, but also makes it easier to use.

[0036] Furthermore, a limiting plate 261 is welded to the end of the fixed column 26 away from the slider 25, and a limiting groove 2711 matching the limiting plate 261 is provided on the bottom wall of the groove of the connecting frame 27. The limiting plate 261 rotates within the limiting groove 2711 to prevent the connecting frame 27 and the slider 25 from separating.

[0037] Furthermore, the vertical groove 32 is covered with a rubber layer 321. There is friction between the rubber layer 321 and the connecting frame 27, which plays a certain role in damping. After stepping on the foot pedal 28, the rubber layer 321 can fix the connecting frame 27 in a certain position, which makes it easier to control the size of the gas flame when cooking.

[0038] Furthermore, a deep groove bearing 31 is embedded in the fixed plate 3, and the valve stem 22 is welded to the rotating inner ring of the deep groove bearing 31. The deep groove bearing 31 not only supports the valve stem 22, but also does not affect the rotation of the valve stem 22, preventing the valve stem 22 from bending when the foot pedal 28 is stepped on.

[0039] Furthermore, the mounting plate 3 is equipped with bolts 33. When installing gas valve components, a through groove smaller than the mounting plate 3 is made in the kitchen cabinet of the restaurant. The mounting plate 3 can then be installed on the cabinet using the bolts 33, making installation convenient. In addition, if the gas valve component is damaged, it can be removed and replaced by loosening the bolts 33.

[0040] like Figure 5 As shown, an external thread 141 is provided on the first gas pipe 14, and a second gas pipe 15 is threadedly connected to the first gas pipe 14. An internal thread 151 matching the external thread 141 is provided on the second gas pipe 15. By twisting the second gas pipe 15, the length of the first gas pipe 14 can be changed, which facilitates connection with the gas pipeline reserved in the kitchen during installation and improves the applicability of gas valve components.

[0041] When using, such as Figure 1 and Figure 2 As shown, pressing down on the right-side foot pedal 28 causes the valve stem 22 to rotate clockwise, opening a connection between the first vent 12 and the second vent 21, allowing gas to flow through the gas valve. When the chef needs to close the gas valve, pressing down on the left-side foot pedal 28 causes the valve stem 22 to rotate counterclockwise, disconnecting the first vent 12 and the second vent 21, thus closing the gas valve.

[0042] Compared with the prior art, the gas valve of this utility model can more conveniently adjust the gas during cooking, which not only improves cooking efficiency, but also effectively avoids the risk of chef's arm being burned due to the inconvenience of turning off the gas, thus ensuring the safety and convenience of the cooking process.
