Description

Gas valve and gas stove comprising same Technical Field The utility model relates to the field of gas cookers, in particular to a gas valve and a gas cooker comprising the same. Background In order to realize the instant opening or closing function, the traditional quick-frying valve is generally required to be independently provided with a special quick-frying channel and an auxiliary control structure (such as an external bypass pipeline, an auxiliary driving mechanism and the like) outside the valve body. The external stir-frying channel needs to be additionally provided with a sealing interface, a connecting piece and a supporting structure, so that the whole volume of the valve is huge, the number of parts is increased, the manufacturing cost is increased, the mounting and maintenance difficulties are increased, the response time of medium flow is prolonged by the circuitous path of the external stir-frying channel, and the instantaneous action requirements in a high-frequency opening and closing or emergency cutting scene are difficult to meet. Disclosure of utility model The utility model aims to overcome the defect that an external stir-frying valve is complex in structure and long in gas flow path in the prior art, and provides a gas valve and a gas stove comprising the same. The utility model solves the technical problems by the following technical scheme: The utility model provides a gas valve, which comprises a plug valve and a stir-frying valve, wherein the plug valve comprises a plug valve body, an air inlet channel, a main valve cavity, a common gas channel, a stir-frying channel and a connecting channel are arranged in the plug valve body, the air inlet of the air inlet channel is used for being communicated with air supply equipment, the air inlet of the main valve cavity is communicated with the air outlet of the air inlet channel, the first air inlet of the common gas channel and the air inlet of the stir-frying channel are both communicated with the air outlet of the main valve cavity, the two ends of the connecting channel are respectively communicated with the second air inlet of the common gas channel and the air outlet of the stir-frying channel, the air outlet of the common gas channel is used for being communicated with a gas mixing chamber, the stir-frying valve comprises a stir-frying valve core and a driving part, at least part of the stir-frying valve core stretches into the connecting channel, and the driving part of the stir-frying valve core is used for controlling the stir-frying valve core to rotate in the connecting channel so as to enable the stir-frying valve core to be switched between a common state and a stir-frying state, and a normal stir-frying state are closed, and the gas channel is not communicated with the common stir-frying channel. In this scheme, set up the stir-fry passageway in the cock valve body inside, the connecting channel is with stir-fry passageway and ordinary gas passageway intercommunication and for setting up the accommodation space that stir-fry valve provided. The drive part drives the quick-frying valve to control the quick-frying channel in a rotary mode, so that the quick-frying channel can be controlled to be opened or closed simply and reliably when the quick-frying channel is arranged in the cock valve body. On the basis that the main valve cavity provides fuel gas for the common fuel gas channel through the first air inlet, the quick-frying channel and the common fuel gas channel share one part of the common fuel gas channel, so that an independent external quick-frying channel is not required to be arranged independently, the added quick-frying channel is connected to the second air inlet of the common fuel gas channel to provide additional fuel gas, and therefore the air supply quantity of the common fuel gas channel is improved, and the quick-frying effect is achieved. By adopting the structure, the internal structure of the cock valve body arranged in the quick-frying channel is greatly simplified, so that the defect that the structure of the gas valve is too complex due to the external quick-frying channel is avoided, and the effect of reducing the time required by gas passing through the quick-frying channel is realized. The quick-frying valve core is provided with a communication cavity, an air inlet and an air outlet of the communication cavity penetrate through the wall surface of the quick-frying valve core, in the normal state, the projection of the air inlet of the communication cavity on the quick-frying channel along the axis direction of the air outlet of the quick-frying channel is not overlapped with the air outlet of the quick-frying channel, and/or the projection of the air outlet of the communication cavity on the normal gas channel along the axis direction of the second air inlet is not overlapped with the second air inlet, in the quick-frying state, the projection of the air inlet of the communication cavity on th
