[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0031] The terms "a", "an", "the", "" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0032] A plug valve according to an embodiment of the utility model comprises a valve body 1, a stir-frying channel component 2 and a control component 3, the valve body 1 comprises a first air outlet channel 11, the stir-frying channel component 2 comprises a mounting shell 21 detachably connected to the air outlet end of the first air outlet channel 11, an air guide cavity 210, an air inlet channel 211, a second air outlet channel 212 and a stir-frying channel 213 are formed in the mounting shell 21, the air inlet channel 211 connects the first air outlet channel 11 and the air guide cavity 210, the air guide cavity 210 connects the second air outlet channel 212 and the air inlet end of the stir-frying channel 213, the air outlet end of the stir-frying channel 213 connects the second air outlet channel 212; the control component 3 is connected to the air inlet end of the stir-frying channel 213, and is used to open or close the stir-frying channel 213. The valve body 1 includes an air inlet 13 and at least one third air outlet channel 14. The gas enters the interior of the valve body 1 through the air inlet 13 and is distributed to the first air outlet channel 11 and / or the third air outlet channel 12. The gas enters the first air outlet channel 11 through the air inlet channel 211 and enters the air guide cavity 210. Since the second air outlet channel 212 is always connected after the air guide cavity 210, the gas entering the air guide cavity 210 can enter the second air outlet channel 212. When the control component 3 receives the stir-frying signal, the stir-frying channel 213 will be opened, so that the gas in the air guide cavity 210 is directly transported to the second air outlet channel 212 near its outlet end through the stir-frying channel 213 to increase the gas output of the second air outlet channel 212 to meet the firepower requirements of the stove when stir-frying. A variety of firepower can be achieved by opening or closing the stir-frying channel 213 through the control component 3. The stir-fry channel assembly 2 in this embodiment is added on the basis of the original valve body 1, and there is no need to change the original product structure, which is convenient for processing and maintenance. The stir-fry channel assembly 2 is through a second air outlet channel 212 that is always connected to the first air outlet channel 11 and a closable explosion-proof channel 213, which can achieve instantaneous increase of the gas volume at the air outlet end of the second air outlet channel 212 during stir-frying, thereby meeting the stir-frying firepower requirements, and has a simple structure and is easy to process.

[0033] In addition, the present application applies the control component 3 to the air inlet end of the stir-frying channel 213, and the flow direction of the gas is the same as the direction of the force applied when the control component 3 closes the stir-frying channel 213, that is, the gas can further compress the stir-frying channel 213, which can effectively improve the air tightness of the stir-frying valve. In addition, the first gas outlet channel 11 and the stir-frying channel component 2 can be used for the outer ring fire channel of the burner head or the central fire channel of the burner head, and the present application does not limit this.

[0034] In a preferred embodiment of the present invention, Figure 1-2The mounting shell 21 shown is also provided with a cut-off hole 214 and an adjustment hole 215, wherein the adjustment hole 215 is connected to the air-guiding cavity 210 and the stir-frying channel 213, and the cut-off hole 214 is connected to the air-guiding cavity 210 and the second air outlet channel 212, wherein the air outlet direction of the cut-off hole 214 is the same as the air outlet direction of the second air outlet channel 212, which can reduce the gas flow loss, effectively increase the air flow velocity, and reduce the pressure in front of the nozzle 41. In the non-stir-frying state, the cut-off hole 214 can make the air-guiding cavity 210 and the second air outlet channel 212 conduct, while the solenoid valve 31 is closed, and the stir-frying channel 213 is closed. Due to the effect of the cut-off hole 214, the pressure in front of the nozzle 41 will drop, and the burner load will reach the rated load at this time; when the stir-frying is started, the solenoid valve 31 is opened, the air-guiding cavity 210 and the adjustment hole 215, stir-frying channel 213 are connected in sequence, and the pressure in front of the nozzle 41 is increased to the normal pressure. Due to the increase in pressure, the flow rate of the nozzle 41 will increase, and the load will increase, and the stir-frying function will be realized.

[0035] In a preferred embodiment of the present invention, Figure 1-2 The control assembly 3 shown includes a solenoid valve 31 and a sealing head 32. The solenoid valve 31 includes a first valve stem 311. The housing of the solenoid valve 31 is detachably connected to the mounting housing 21. The fixed end of the first valve stem 311 is connected to the housing of the solenoid valve 31. The free end of the first valve stem 311 is inserted into the air guide cavity 210. The sealing head 32 is located in the air guide cavity 210 and connected to the free end of the first valve stem 311. The sealing head 32 can abut against or move away from the air inlet end of the regulating hole 215 under the drive of the first valve stem 311 to open or close the stir-frying channel 213. When stir-frying is required, the first valve stem 311 drives the sealing head 32 to move in a direction away from the air inlet end of the regulating hole 215, so that the gas enters the stir-frying channel 213 through the regulating hole 215. When stir-frying is not needed, the first valve stem 311 moves with the sealing head 32 toward the air intake direction of the regulating hole 215 and makes the sealing head 32 abut against the air intake end of the regulating hole 215, so that the gas intake method and the action direction of the sealing head 32 on the regulating hole 215 are the same, and the flowing gas is pressed against the regulating hole 215 by the sealing head 32, which can effectively improve the sealing effect of the sealing head 32 on the regulating hole 215. If the sealing head 32 is installed at the air outlet end of the regulating hole 215, the flowing gas will push the sealing head 32 open, which is prone to air leakage, and the service life of the product is also relatively shorter than that of the present application. In addition, the solenoid valve 31 needs to overcome the force of the flowing gas, which consumes more energy than the present application. Therefore, the present application uses a gas positive pressure solenoid valve to avoid high-pressure gas from rushing open the solenoid valve, which can improve the air tightness of the product.

[0036] In a preferred embodiment of the present invention, Figure 1-2The aperture of the intercepting hole 214 shown is smaller than the aperture of the regulating hole 215, and the aperture of the intercepting hole 214 is 0.9mm~2mm. The size of the intercepting hole 214 will directly affect the front pressure of the nozzle 41. If the intercepting hole 214 is designed to be too small, the pressure in front of the nozzle 41 will be seriously reduced, which will not only affect the ejection ability of the nozzle 41 and cause the flue gas to rise, but also because the pressure drop is large, it will make the rated heat load of the burner difficult to achieve, and another ring is required to increase the heat load to make up for the loss of the load under the rated state, so that the load ratio of each ring of the burner is relatively different, and the burner is difficult to debug. Finally, the pressure difference before and after stir-frying changes greatly, and it may also make the stir-frying load exceed 10% (not in compliance with national standards), and excessive increase in heat load may lead to problems such as unqualified flue gas, so the intercepting hole cannot be too small. After multiple verifications, the aperture of the intercepting hole 214 is set to 0.9mm~2mm in this application.

[0037] In a preferred embodiment of the present invention, Figure 1-2 The plug valve shown is also provided with a damper adjustment component 4, which is connected to the outlet end of the second outlet channel 212. The damper adjustment component 4 can be directly connected to the burner head, realizing the direct connection between the plug valve and the burner head. Compared with the connected pipe stir-frying platform, the structure is simpler and the cost is lower, and the gas supply from the second outlet channel 212 to the burner head can also be adjusted.

[0038] In a preferred embodiment of the present invention, Figure 1-2 The damper adjustment assembly 4 shown includes a nozzle 41, a damper plate 42 and an elastic element 43. The nozzle 41 is connected to the outlet end of the second outlet channel 212. The damper plate 42 is rotatably connected to the outer periphery of the nozzle 41. The elastic element 43 is sleeved on the nozzle 41. One end of the elastic element 43 is fixed to the nozzle 41, and the other end of the elastic element 43 is abutted against the damper plate 42. The damper plate 42 is used to adjust the air flow rate of the nozzle 41 to the ejector tube. The present application directly connects the nozzle 41 by the stir-fry channel assembly 2, so that the structure is simpler, the cost is lower, and it is more advantageous.

[0039] In a preferred embodiment of the present invention, Figure 1-2 The valve body 1 shown also includes a second valve stem 12, which is rotatably connected to the valve body 1, and is connected to a micro switch 5. The micro switch 5 gives an ignition signal according to the rotation of the second valve stem 12.

[0040] A gas stove according to an embodiment of the utility model comprises a burner head and a plug valve as described above, and a stir-fry channel assembly 2 is connected to the burner head. The gas stove in this embodiment comprises any of the plug valves described above. Since the plug valves described above have the above technical effects, the gas stove having the plug valves described above should also have the same technical effects. The nozzle 41 and the damper plate 42 on the stir-fry channel assembly 2 of the present application are directly connected to the ejector pipe on the burner head, eliminating the connecting pipe, making the structure simpler and the cost lower.
