The second gas outlet branch pipe 1132 does not occupy too much horizontal position. The distance between the first gas outlet branch pipe 1131 and the second gas outlet branch pipe 1132 is reduced. The structure of the plug valve is more compact. The use of the stove shell and even the kitchen space is enhanced.

[0056] In a preferred embodiment of the present application, as shown in FIG. 5, Figures 1-5The first inclined pipe 112 is connected with a first flange 1121 used for connecting with the gas outlet pipe 113. The thickness of the first flange 1121 is greater than or equal to 5 mm. In the application, the thickness of the first flange 1121 refers to the distance between the flange surface of the first flange 1121 and the gas outlet end of the first inclined pipe 112. By increasing the thickness of the first flange 1121, the thickness of the first flange 1121 is greater than or equal to 5 mm, and when the first electromagnetic valve 14 is not needed to be arranged outside the ring, the first flange 1121 can be tapped and then connected with a straight aluminum pipe, so that a universal valve structure without explosive frying is realized, and the application range is increased.

In the application, the first electromagnetic valve 14 is arranged on the outside of the outer ring gas outlet assembly 11. The movement direction of the sealing head 142 and the central axis of the first gas outlet branch pipe 1131 are inclinedly arranged. Not only can the first electromagnetic valve 14 interfere with the main electromagnetic valve, but also the valve body 10 can be thinnest in the vertical direction even if the first electromagnetic valve 14 is installed. The height of the whole valve body 1 will not be increased, and interference with the panel will not occur. The internal space of the stove bottom shell is fully utilized.

[0059] Specifically, the first flange 1121 is provided with a sealing groove 1122 inwardly recessed on the side close to the gas outlet pipe 113, and a sealing ring is arranged in the sealing groove 1122.

The second flange 1133 and the third flange 1134 are both rhombic and arranged staggeredly, facilitating the mounting of the first electromagnetic valve 14, and through the inclined design of the long side of the third flange 1134 and the central axis of the first gas outlet branch pipe 1131, especially when 20°≤b≤90°, not only can the first electromagnetic valve 14 interfere with the main electromagnetic valve, but also can make the valve body 10 be thinnest in the vertical direction even if the first electromagnetic valve 14 is mounted, the height of the overall valve body 1 will not be increased, and will not interfere with the panel, and the internal space of the stove bottom shell is fully utilized.

[0060] Preferably, the top outer periphery of the valve body 1 is connected with a first mounting plate 15 for mounting a first micro switch, providing a basis for the diversity of the later functional platform.

[0061] The utility model embodiment provides a plug valve, such as Figures 6-9 The plug valve comprises the above-mentioned valve body 1, valve core 2, valve rod 3 and delay mechanism 4, the valve core 2 is connected to the valve body 10, comprising valve core cavity 20, first gas passage corresponding to the outer ring gas outlet and second gas passage corresponding to the inner ring gas outlet;The valve rod 3 is connected to the valve core 2, for driving the valve core 2 to rotate;The delay mechanism 4 is inserted and elastically connected in the inside of the valve core cavity 20, and can abut on the valve rod 3 configured as a depressed state, wherein the delay mechanism 4 can move up and down with the ignition process of the valve rod 3 to connect or disconnect the first gas passage. Figures 6-9 It can be known that the outer ring gas outlet assembly 11 is provided with an outer ring passage and a stir-frying passage connected to the outer ring passage, and the inner ring gas outlet assembly 12 is provided with an inner ring passage 120, since the first gas passage connects the outer ring passage, and the outer ring passage connects the stir-frying passage, at this time, the gas can only enter the second gas passage and the inner ring passage 120 in turn and be ignited, at this time, the inner ring is ignited, the outer ring is extinguished and there is no gas accumulation thereon, with the loosening of the knob, the valve rod 3 and the delay mechanism 4 move upward, the first gas passage is connected, the outer ring passage is also connected, and the outer ring is ignited by the inner ring, which can avoid the problem of burner deflagration and improve the safety performance of the product. The delay mechanism 4 is introduced into the inside of the valve core 2, and the delay mechanism 4 can be used to control the connection and disconnection of the outer ring passage, realize the delayed outer ring gas outlet, prevent ignition deflagration, and effectively improve the safety performance of the product and the user experience.

[0062] Specifically, in this embodiment, the valve core 2 has an outer ring air outlet 22, an air inlet 21, and an inner ring air outlet 23 opened from top to bottom along its side wall. The outer ring air outlet 22, the air inlet 21, and the inner ring air outlet 23 correspond to the outer ring air outlet, the air inlet, and the inner ring air outlet on the valve body 10, respectively. The air inlet 21 and the outer ring air outlet 22 are connected to form a first air outlet channel, and the air inlet 21 and the inner ring air outlet 23 are connected to form a second air outlet channel, so that the delay mechanism 4 can open and close the outer ring channel.

[0063] In a preferred embodiment of this utility model, such as Figures 7-9 The inner wall of the valve core cavity 20 shown is connected to a limiting ring 24 for cooperating with the delay mechanism 4. The delay mechanism 4 includes a push rod 41, a sealing gasket 42, and an elastic element. The top of the push rod 41 cooperates with the valve stem 3, and the bottom of the push rod 41 is inserted into the valve core cavity 20. The sealing gasket 42 is connected to the bottom of the push rod 41 and can be inserted into and abut against the inner circumference of the limiting ring 24 to disconnect the first air outlet passage. The elastic element is connected between the push rod 41 and the limiting ring 24 to push the push rod 41 to reset. In this application, the limiting ring 24 is connected to the area of ​​the valve core cavity 20 located between the outer ring outlet 22 and the inlet 21. The outer periphery of the sealing gasket 42 is provided with a sealing surface that seals with the limiting ring 24. When the valve stem 3 is pressed down and inserted into the valve core 2 for ignition, the valve stem 3 drives the push rod 41 and the sealing gasket 42 to move downward, causing the sealing gasket 42 to insert and abut against the limiting ring 24. This prevents the gas entering the inlet 21 from entering the outer ring outlet 22 and allows it to enter the inner ring outlet 23, thereby disconnecting the first outlet channel. When the knob is removed by external force, the valve stem 3 is reset under the action of the return spring. The elastic element pushes the rod 41 and the sealing gasket 42 upward, connecting the first outlet channel. Then, the outer ring channel begins to ventilate, and the outer ring is ignited by the inner ring flame. This achieves the goal of delaying the outer ring outlet and ignition, preventing the problem of ignition deflagration, and improving product safety.
