[0021] Example 1

[0022] Combined with Figure 1-4 The present embodiment provides a plug valve, comprising a main body 10, a connecting pipe 11, a valve control part 12 and an outer ring air outlet part 13; a rotating shaft 14 is arranged on the main body 10, and the rotating shaft 14 is used to connect with the knob of the cooker, and an inner cavity for circulating gas is arranged in the main body 10; the interior of the connecting pipe 11 is hollow to form a connecting cavity, and the interior of the valve control part 12 is hollow to form a control cavity 120, and the control cavity 120 is connected with the inner cavity through the connecting cavity; the interior of the outer ring air outlet part 13 is hollow to form an air outlet cavity 130, and a gas channel 150 is arranged between the air outlet cavity 130 and the control cavity 120, and the control cavity 120 and the air outlet cavity 130 are connected through the gas channel 150; there is an angle between the axis a of the rotating shaft 14 and the axis b of the air outlet cavity 130.

[0023] A plug valve of the present embodiment is composed of a main body 10, a connecting pipe 11, a valve control part 12 and an outer ring air outlet part 13. The inner cavity of the main body 10 and the control cavity 120 of the valve control part 12 are connected to each other through the connecting cavity of the connecting pipe 11. The control cavity 120 is then connected to the air outlet cavity 130 of the outer ring air outlet part 13 through the gas channel 150, thereby realizing the circulation of gas between the main body 10 and the outer ring air outlet part 13.

[0024] In view of the usage defects of the existing stopcock, in the present embodiment, there is an angle between the axis line a of the rotating shaft 14 and the axis line b of the air outlet cavity 130. The angle needs to be set to 90° according to the specific stove product. In other embodiments, the angle can also be set to 45°, 60° or 30°, so that there is an angle between the rotating shaft 14 and the outer ring air outlet portion 13, forming a non-0 degree valve, thereby improving the adaptability of the stopcock to better adapt to most stoves.

[0025] The valve control part 12 in this embodiment is used to assemble the solenoid valve to realize the control of the gas conduction between the main body 10 and the outer ring gas outlet part 13. In one embodiment, the solenoid valve is fixedly connected to the valve control part 12, and the solenoid valve includes a valve body 16, a valve stem 17 and a spring 18 located in the control chamber 120. The valve stem 17 is movably arranged relative to the valve body 16 and is magnetically matched with the valve body 16. A seal 19 is fixedly arranged at the end of the valve stem 17. The spring 18 is located at the outer periphery of the valve stem 17, one end of the spring 18 abuts against the valve body 16, and the other end of the spring 18 abuts against the seal 19; the connection between the gas channel 150 and the control chamber 120 constitutes a first communication port 201, the valve stem 17 faces the first communication port 201, and the seal 19 is used to realize the opening and closing of the first communication port 201.

[0026] Therefore, based on the above-mentioned embodiment, when the solenoid valve receives an external electrical signal and changes the suction state between the valve body 16 and the valve stem 17, the sealing state of the sealing member 19 for the first communication port 201 can be changed, and the opening and closing control of the gas channel 150 can be realized, thereby controlling the gas to flow into the gas outlet cavity 130 of the outer ring gas outlet portion 13. Among them, the external electrical signal can be energized and de-energized by the solenoid valve, thereby controlling the suction and release of the valve stem 17, and the spring 18 can form a thrust on the sealing member 19 through its own elastic force when the valve stem 17 is released, thereby pushing the sealing member 19 to close the first communication port 201. Among them, the sealing member 19 can be a sealing ring made of rubber material.

[0027] In a further embodiment, the connection between the communication cavity and the control cavity 120 forms a second communication port 202, and the second communication port 202 is located on the side of the seal 19 away from the first communication port 201. At this time, since the gas flows from the second communication port 202 to the first communication port 201, and the seal 19 is located on the flow path of the gas, the pressure of the gas itself will exert pressure on the seal 19 in the direction of the first communication port 201, so that the seal 19 more tightly seals the first communication port 201. This embodiment makes it possible that within a certain range, the greater the gas pressure, the better the sealing effect of the seal 19 on the first communication port 201, and there will be no problem of gas leakage caused by excessive gas pressure.

[0028] In another embodiment, a sealing boss 20 protruding toward the sealing member 19 is provided at the first communication port 201, and the sealing boss 20 is used to abut against the sealing member 19. In this embodiment, the sealing boss 20 can better contact with the sealing member 19, so that the sealing member 19 is fully deformed, thereby ensuring the sealing effect.

[0029] In order to improve the processing convenience of the plug valve, in one embodiment, the main body 10, the connecting pipe 11, the valve control part 12 and the outer ring air outlet 13 are integrally die-cast. Since the plug valve is generally made of aluminum, it is preferably die-casted with aluminum. In this embodiment, since the main body 10, the connecting pipe 11, the valve control part 12 and the outer ring air outlet 13 are one component, the intermediate connection parts are reduced, the product cost is reduced, and the probability of air leakage is reduced.

[0030] In a further embodiment, the axis line c of the control cavity 120 is parallel to the axis line b of the air outlet cavity 130. This design can make the plug valve easier to produce and process. On the one hand, the main body 10, the connecting pipe 11, the valve control part 12 and the outer ring air outlet part 13 are die-cast. The parallel arrangement of the control cavity 120 and the air outlet cavity 130 can realize the convenient disengagement of the slider of the cavity mold in the same direction during die casting. Obviously, if the control cavity 120 is not parallel to the air outlet cavity 130, the mold slider needs to be disengaged in all directions, and the mold structure is complicated and difficult to process during die casting. On the other hand, in the finishing of the die casting, the control cavity 120 and the air outlet cavity 130 extend in the same direction, so the processing machine does not need a multi-axis machine tool, and the tool can be processed in the coaxial direction.

[0031] In order to facilitate processing, in other embodiments, an extended boss 21 is provided on the outside of the valve control part 12, and an opening 210 communicating with the communication cavity and the control cavity 120 is provided on the extended boss 21, and a plug 22 is provided at the opening 210. In this embodiment, the extended boss 21 and the opening 210 thereon are provided for the ejection of the mold slider and the entry of the tool during the finishing process, so as to facilitate the processing of the communication cavity of the connecting pipe 11. The plug 22 is provided for closing the opening 210 to ensure the sealing of the plug valve.

[0032] Example 2

[0033] Combined with Figure 1-4 This embodiment proposes a stove, including the stopcock recorded in the technical solution of Example 1.

[0034] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
