Referring to fig. 1, a gas valve for multiple gas sources comprises: the valve comprises a valve body 100, a valve core 300 and a plugging assembly, wherein the valve body 100 is provided with an air inlet channel 130 and an air outlet channel 140, the air outlet channel 140 comprises a first channel 147, a second channel 143 and an outlet part 120, and the first channel 147 and the second channel 143 are communicated with the outlet part 120; the valve core 300 is rotatably arranged in the valve body 100, the valve core 300 is provided with an air inlet 310 and an air outlet 350 which are communicated with each other, and the air inlet 310 is communicated with the air inlet channel 130; the valve spool 300 can cause the air outlet 350 to communicate with the first passage 147 and the second passage 143 in rotation; the blocking assembly comprises a closing part 400 which is rotatably arranged in the second channel 143, a through hole 450 is arranged on the closing part 400, and the flow area of the second channel 143 can be reduced or the second channel 143 can be closed when the closing part 400 rotates.
After the gas enters the valve core 300 from the gas inlet channel 130 and the valve core 300 rotates until the gas outlet 350 is communicated with the first channel 147 and the second channel 143, the gas flows to the gas outlet channel 140 and flows out from the gas outlet part. When the closing piece 400 is rotated, the communication range of the second passage 143 is gradually reduced until the closing piece 400 closes the second passage 143, and the total flow cross-sectional area of the first passage 147 and the second passage 143 is changed, so that the gas outlet passage 140 has a variable gas flow cross-sectional area, and can be adapted to different gas sources. Through adjusting the gas flow cross-sectional area of outlet channel 140, can directly, effectively make the pneumatic valve match in different air supplies, consequently change the air supply after, need not to change the stove, so this application has the advantage of using manpower and materials sparingly. Also, multiple adjustments of the gas flow area by the valve spool 300 and closure member 400 may provide multi-step flow rate precision control for the gas valve, thereby allowing the user more control step options.
Specifically, the valve cartridge 300 is connected with the valve stem 200.
It is contemplated that outlet channel 140 may be further subdivided into a greater number of branches, third channel, fourth channel, etc., wherein it is only necessary that there be at least one branch in direct communication with outlet portion 120 and that a closure 400 be disposed within at least one branch. The specific implementation manner may be adjusted according to the actual situation, and is not limited herein.
In some embodiments, referring to fig. 2, the closure 400 is provided with a through hole 450, and the rotation of the closure 400 can bring the through hole 450 into communication with the second channel 143. Rotation of the closure 400 will rotate the aperture 450. The rotation of the through hole 450 can bring the central axis of the through hole to coincide with the central axis of the second channel 143, so that the through hole 450 communicates with the two ends of the second channel 143. The coincidence of the two central axes enables the through hole 450 to open the second channel 143 to the maximum extent, so that a larger adjustment range of the total flow cross-sectional area of the fuel gas is obtained, and the gas source device is further suitable for more gas sources.
In some embodiments, referring to FIG. 3, the central axis of rotation of the closure 400 is orthogonal to the central axis of the through-hole 450. Due to the orthogonal relationship, when the closing member 400 rotates, the through hole 450 is driven to turn over relative to the second channel 143, so that the through hole 450 and the second channel 143 are deflected and dislocated, and the through hole 450 and the second channel 143 can be isolated from each other to close the second channel 143.
Of course, the rotation direction and the axial position of the through hole 450 may be configured in other manners, and it is only necessary to satisfy the condition that the through hole 450 can communicate with both ends of the second channel 143 and can close the second channel 143 when rotating. The specific implementation manner may be adjusted according to the actual situation, and is not limited herein.
In some embodiments, referring to fig. 4, the gas inlet 310 is located on an end surface of the valve element 300, the gas outlet 350 is located on a side wall of the valve element 300, and the gas inlet 310 and the gas outlet 350 communicate with each other inside the valve element 300. Since the valve body 300 rotates only by its rotation without changing the position of the end surface thereof, the intake port 310 provided in the end surface of the valve body 300 can stably intake air when the valve body 300 rotates. When the valve element 300 rotates, the position of the air outlet 350 on the side wall of the valve element is changed, so that the opening and closing of the air outlet 350 and the air outlet channel 140 can be directly and effectively realized by rotating the valve element 300.
In some embodiments, referring to fig. 4, the plurality of air outlets 350 are provided, the plurality of air outlets 350 are divided into two groups, each group of air outlets 350 is distributed around the valve core 300, and the two groups of air outlets 350 are correspondingly disposed at the lower sides of the first and second passages 147 and 143. The two sets of air outlets 350 can simultaneously vent both first channel 147 and second channel 143, thereby ensuring that the enclosure 400 in the second channel 143 does not affect the venting of the first channel 147. The plurality of air outlets 350 can reduce the rotation amplitude of the valve element 300 when the two air outlets 350 are switched, thereby being convenient for users to use.
In some embodiments, referring to FIG. 5, at least one of the outlet ports 350 of each set of outlet ports 350 has an air guide channel 355 disposed therein. The air guide groove 355 may allow the flow sectional area of the gas to be constant for a certain distance when the valve core 300 is rotated, thereby facilitating a user to select a constant fire.
In some embodiments, referring to FIG. 5, the size of the same set of air outlets 350 decreases progressively in a clockwise or counterclockwise direction. The air outlet 350, which is gradually decreased, allows the user to select a gear with a certain amount of fire, thereby facilitating the user to select the corresponding fire.
In some embodiments, referring to fig. 6, the air outlet 350 includes a bar-shaped hole 357, and when the bar-shaped hole 357 rotates to face the outlet portion 120, the first channel 147 and the second channel 143 communicate with both ends of the bar-shaped hole 357, respectively. The strip-shaped holes 357 directly, simply and directly communicate with the first channel 147 and the second channel 143 at the same time, so as to ensure that the first channel 147 can stably vent gas, and the second channel 143 can adjust the total flow cross-sectional area of the gas.
Further, both ends of the bar-shaped hole 357 are connected with air guide grooves 355.
In some embodiments, referring to fig. 2, the closure assembly comprises an operating portion 500 provided on the closure 400, the operating portion 500 extending to the outside of the valve body 100, the operating portion 500 being provided with a strip-shaped groove. After the user stretched into the bar groove with instruments such as a word screwdriver, can drive operating portion 500 through the bar groove and rotate to make through-hole 450 and second passageway 143 take place the dislocation, and then simply, directly adjust the total flow cross sectional area of gas, in order to match different air supplies.
A second aspect of the present invention provides an embodiment of a stove, comprising the above gas valve adapted to multiple gas sources. After the gas enters the valve core 300 from the gas inlet channel 130 and the valve core 300 rotates until the gas outlet 350 is communicated with the first channel 147 and the second channel 143, the gas flows to the gas outlet channel 140 and flows out from the gas outlet part. When the closing member 400 is rotated, the communication range of the through hole 450 and the second passage 143 is gradually reduced until the closing member 400 blocks the second passage 143, and the total flow cross-sectional area of the first passage 147 and the second passage 143 is changed, so that the gas outlet passage 140 has a variable gas flow cross-sectional area, and thus can be adapted to different gas sources. Through adjusting the gas flow cross-sectional area of outlet channel 140, can directly, effectively make the pneumatic valve match in different air supplies, consequently change the air supply after, need not to change the stove, so this application has the advantage of using manpower and materials sparingly. Also, multiple adjustments of the gas flow area by the valve spool 300 and closure member 400 may provide multi-step flow rate precision control for the gas valve, thereby allowing the user more control step options.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
