Referring to fig. 1 to 6, a multi-channel plug valve of the present invention includes: the valve body 100, the inside of the valve body 100 is provided with an air inlet cavity, and the side part of the valve body 100 is provided with an air inlet channel 120, a long open fire air transmission channel 130, a first air transmission channel 140 and a second air transmission channel 150 which are communicated with the air inlet cavity; the valve core 200 is rotatably arranged in the valve body 100 and positioned in the air inlet cavity, and is used for communicating or isolating at least one of the open flame air transmission channel 130, the first air transmission channel 140 and the second air transmission channel 150 with the air inlet cavity; the open flame gas transmission channel 130, the first gas transmission channel 140 and the second gas transmission channel 150 are sequentially and circumferentially distributed around the rotation axis of the valve core 200, and the apertures of the open flame gas transmission channel 130, the first gas transmission channel 140 and the second gas transmission channel 150 are sequentially increased; the spool 200 has a closed position disposed about the clockwise direction, a first operating position, a second operating position, and a third operating position; when the valve core 200 is in the first working position, the open flame gas transmission channel 130 is communicated with the gas inlet cavity, and the first gas transmission channel 140 and the second gas transmission channel 150 are separated from the gas inlet cavity; when the valve core 200 is in the second working position, the open flame gas transmission channel 130 and the first gas transmission channel 140 are both communicated with the gas inlet cavity, and the second gas transmission channel 150 is separated from the gas inlet cavity; when the valve core 200 is at the third working position, the open flame gas transmission channel 130, the first gas transmission channel 140 and the second gas transmission channel 150 are all communicated with the gas inlet cavity; alternatively, the open flame gas delivery channel 130 and the second gas delivery channel 150 are both communicated with the gas inlet cavity, and the first gas delivery channel 140 is isolated from the gas inlet cavity.
The multi-channel plug valve with the structure can communicate at least one of the first gas transmission channel 140 and the second gas transmission channel 150 with the long open flame gas transmission channel 130 through the rotary valve core 200, so that the long open flame and the flames with different power sizes are formed, different cooking modes are adapted, a plurality of single-channel plug valves are not required to be arranged to control the on-off of the channels, the use convenience is improved, the cost is reduced, the regulation range of the firepower is far larger than that of the single-channel plug valve, and the multi-channel plug valve is suitable for the needs of commercial gas stoves such as restaurants. When the valve core 200 is at the closed position, the open flame gas transmission channel 130, the first gas transmission channel 140, and the second gas transmission channel 150 are all separated from the gas inlet cavity; because the apertures of the long-open-fire gas transmission channel 130, the first gas transmission channel 140 and the second gas transmission channel 150 are sequentially increased, when the valve core 200 is in the second working position, the long-open-fire gas transmission channel 130 and the first gas transmission channel 140 are communicated with the gas inlet cavity, so that a long-open-fire flame and a flame with smaller flame power are formed; when the valve core 200 is in the third working position, two embodiments are provided, wherein the first embodiment is that the long-open-fire gas transmission channel 130, the first gas transmission channel 140 and the second gas transmission channel 150 are communicated with the gas inlet cavity, so that a long-open fire, a flame with smaller fire and a flame with larger fire are formed, and the maximum fire is achieved; the second embodiment is that the long-open-fire gas transmission channel 130 and the second gas transmission channel 150 are both communicated with the gas inlet cavity, and the first gas transmission channel 140 is separated from the gas inlet cavity, so that a long-open fire and a circle of flame with larger firepower are formed, and the requirements of various cooking modes of the commercial gas stove are met.
Referring to fig. 1 and 6, in some embodiments of the present invention, the valve core 200 is provided with a first air outlet 210 and a second air outlet 220 which are spaced apart along the length direction thereof, the first air outlet 210 communicates the open flame air transmission channel 130 with the air inlet cavity, and the valve core 200 can enable the second air outlet 220 to communicate with the first air transmission channel 140 or the second air outlet 220 to communicate with the second air transmission channel 150 when rotated. It will be appreciated that when the valve core 200 is rotated to the second operating position, the second air outlet 220 communicates with the first air delivery channel 140 to form a flame with a smaller flame power, and when the valve core 200 is rotated to the third operating position, the second air outlet 220 communicates with the second air delivery channel 150 to form a flame with a larger flame power, thereby realizing the switching operation of the flame power levels of the two gear positions. During this time, first air outlet 210 remains in communication with open flame air delivery conduit 130 to form an open flame that avoids flameout during use. In addition, since the valve core 200 maintains the communication relationship between the first air outlet 210 and the open flame air delivery channel 130 in a larger rotation angle range, more positions need to be occupied in the circumferential direction of the valve core 200, so that the space reserved for the second air outlet 220, the first air delivery channel 140 and the second air delivery channel 150 is insufficient, and the first air outlet 210 and the second air outlet 220 are distributed at intervals along the length direction of the valve core 200, which can solve the above problems and reduce the difficulty of production and processing.
Referring to fig. 2, 3, 4 and 6, in some embodiments of the present invention, the valve core 200 is provided with a third air outlet 230 at one side of the second air outlet 220, the third air outlet 230 and the second air outlet 220 are circumferentially spaced around the valve core 200, and the valve core 200 can rotate until the second air outlet 220 is communicated with the second air delivery channel 150, and the third air outlet 230 is communicated with the first air delivery channel 140. When the multi-channel plug valve with the above structure is adopted, when the valve core 200 rotates to the third working position, the second air outlet 220 is communicated with the second air transmission channel 150, and the third air outlet 230 is communicated with the first air transmission channel 140, so that a flame with smaller flame power and a flame with larger flame power can be formed at the same time, and the superposition of flame power is realized.
Referring to fig. 2 and 3, in some embodiments of the invention, to further extend the range of fire adjustment, the valve spool 200 can be rotated between a first operating position and a second operating position to adjust the overlap between the second air outlet 220 and the first air delivery passage 140; referring to fig. 3 and 4, the valve spool 200 is rotatable between a second operating position and a third operating position to adjust the degree of overlap between the second air outlet port 220 and the second air delivery passage 150 and the degree of overlap between the third air outlet port 230 and the first air delivery passage 140. It will be appreciated that when the valve element 200 is in the first working position, the second air outlet 220 is not connected to the first air delivery channel 140, and when the valve element 200 is in the second working position, the second air outlet 220 is opposite to the first air delivery channel 140, i.e. the contact ratio is the highest, the gas flow output from the first air delivery channel 140 is the largest, and the contact ratio between the second air outlet 220 and the first air delivery channel 140 gradually increases during the movement of the valve element 200 from the first working position to the second working position. Similarly, during the movement of the valve element 200 from the second operating position to the third operating position, the contact ratio between the second air outlet 220 and the second air delivery passage 150 gradually decreases, and the contact ratio between the third air outlet 230 and the first air delivery passage 140 gradually increases until the gas flow rate output from the first air delivery passage 140 and the gas flow rate output from the second air delivery passage 150 are maximized when the valve element 200 rotates to the third operating position.
Referring to fig. 2 to 4 and 6, in some embodiments of the present invention, the valve core 200 is provided with a partition 240 between the second air outlet 220 and the third air outlet 230, the partition 240 is recessed inward toward the center of the valve core 200 to form a communication groove 250 that communicates the second air outlet 220 and the third air outlet 230, and when the partition 240 faces the first air delivery channel 140, the third air outlet 230 communicates with the first air delivery channel 140 through the communication groove 250. It should be noted that, in the process of rotating the valve core 200 from the second working position to the third working position, the overlapping portion between the second air outlet 220 and the first air delivery channel 140 may decrease, so that the air flow output from the first air delivery channel 140 decreases suddenly, at this time, the air in the air inlet cavity may enter the first air delivery channel 140 after passing through the third air outlet 230 and the communication groove 250 until the second air outlet 220 faces the second air delivery channel 150 and the third air outlet 230 faces the first air delivery channel 140 after the valve core 200 rotates to the third working position.
In some embodiments of the present invention, in order to achieve the gear adjustment effect, an angular positioning mechanism is provided between the valve core 200 and the valve body 100, and the angular positioning mechanism can stabilize the valve core 200 in the second working position or the third working position. In this embodiment, the angular positioning mechanism includes a first positioning groove disposed on the valve body 100 and corresponding to the second working position and a second positioning groove corresponding to the third working position, and correspondingly, a ball structure capable of entering and exiting the first positioning groove and the second positioning groove is disposed at an end of the valve core 200 extending out of the valve body 100, and the ball structure specifically includes a spring and a positioning ball, and the positioning ball is driven by the spring to enter the first positioning groove and the second positioning groove.
Referring to fig. 6, in some embodiments of the present invention, the input port of the second gas transmission channel 150 is a waist-shaped through hole, the waist-shaped through hole extends along the length direction of the valve body 100, the shape and size of the second gas outlet 220 are consistent with those of the waist-shaped through hole, the input port of the first gas transmission channel 140 and the third gas outlet 230 are both circular through holes, and the diameter size of the circular through holes is consistent with the width size of the waist-shaped through hole. It can be appreciated that when the second air outlet 220 is aligned with the input port of the first air delivery channel 140, since the cross section of the waist-shaped through hole is larger than that of the circular through hole, the opening degree of the first air delivery channel 140 is maximized; when the second air outlet 220 is aligned with the input port of the second air delivery channel 150, the shapes and sizes of the second air outlet 220 and the input port of the second air delivery channel 150 are completely matched, so that two different output flows can be achieved by using one second air outlet 220.
Referring to fig. 5 and 6, in some embodiments of the present invention, the first air outlet 210 includes an arc-shaped air guide groove 211 provided around the outer circumferential wall of the valve cartridge 200, and the bottom of the arc-shaped air guide groove 211 is provided with an air outlet hole 212 communicating with the air inlet chamber; when the valve core 200 is at the closed position, the long open flame gas transmission channel 130 is isolated from the arc gas guide groove 211; when the valve core 200 is in the first working position, the second working position and the third working position, the open flame gas transmission channel 130 is communicated with the arc-shaped gas guide groove 211. The provision of the arcuate air guide slot 211 ensures that the valve core 200 remains in communication between the open flame air delivery channel 130 and the air intake cavity over a relatively large angular range of rotation.
Referring to fig. 1, in some embodiments of the present invention, a valve body 100 includes a cylindrical part, an inner passage of the cylindrical part forms an air intake chamber, an air intake passage 120, a long open flame air transmission passage 130, a first air transmission passage 140 and a second air transmission passage 150 are formed at an outer circumferential sidewall of the cylindrical part, a valve core 200 is rotatably provided at one end of the cylindrical part, an electromagnetic valve 300 is provided at the other end of the cylindrical part, a switch opening is provided in the interior of the cylindrical part, and the electromagnetic valve 300 can close the switch opening to isolate the air intake passage 120 from the air intake chamber. Specifically, the middle part of the valve core 200 is generally provided with a push rod capable of pushing the electromagnetic valve 300, the electromagnetic valve 300 is connected in a circuit with a thermocouple, the thermocouple is positioned in a region where a flame is positioned, when flameout, the circuit is disconnected, the electromagnetic valve 300 loses magnetic force, and therefore the switch opening is closed, the function of blocking the air inlet channel 120 is achieved, and gas leakage is prevented.
