DETAILED DESCRIPTION

[0037] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] The following describes a gas valve 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0039] like Figures 1-16 As shown, the gas valve 1 according to an embodiment of the present invention includes a valve body 100 and a valve core 200 .

[0040] The valve body 100 comprises a housing chamber 101, an air inlet passage 110, a first air outlet passage 120, and a second air outlet passage 130. The first air outlet passage 120 is adapted to communicate with the inner ring gas passage of the gas stove burner and is in communication with the housing chamber 101 via a first air vent 121. The second air outlet passage 130 is adapted to communicate with the outer ring gas passage of the gas stove burner and is in communication with the housing chamber 101 via a second air vent 131. The valve core 200 is rotatably fitted within the housing chamber 101. The valve core 200 comprises a sub-cavity 201 and an air passage 210 in communication with the sub-cavity 201. The air inlet passage 110 is in communication with the sub-cavity 201. The air passage 210 can selectively communicate with the first air vent 121 and / or the second air vent 131 when the valve core 200 rotates.

[0041] What needs to be understood here is that "the air hole 210 can be selectively connected with the first air hole 121 and / or the second air hole 131 when the valve core 200 rotates" means that during the rotation of the valve core 200, the air hole 210 can be connected with the first air hole 121, or the air hole 210 can be connected with the second air hole 131, or the air hole 210 can be connected with the first air hole 121 and the second air hole 131 at the same time.

[0042] For example, a gas valve 1 is a valve structure used to manually adjust and control the on / off flow of gas and to regulate the gas flow rate. The gas valve 1 comprises a valve body 100, a valve core 200, a valve stem, a microswitch, and other additional devices such as a solenoid valve. Specifically, the gas valve 1 can be a gas cock valve. Its main operating principle is as follows: gas from the gas source enters the gas valve 1 through the air inlet channel 110 of the valve body 100, passes through the solenoid valve, and then enters the valve core 200. Finally, it passes through the air hole 210 of the valve core 200 and connects to the first air outlet channel 120 and / or the second air outlet channel 130, thereby providing gas to the gas stove burner through the air outlet channels.

[0043] According to the gas valve 1 of the embodiment of the present invention, a valve body 100 and a valve core 200 are provided, so that the valve core 200 is rotatably engaged in the accommodating cavity 101 of the valve body 100. Thus, by rotating the valve core 200, the gas supply of the gas stove can be adjusted, thereby facilitating the adjustment of the fire power of the gas stove burner.

[0044] Furthermore, by making the air hole 210 selectively communicate with the first air hole 121 and / or the second air hole 131 when the valve core 200 is rotated, when the valve core 200 is rotated to make the air hole 210 communicate with the first air hole 121, the gas can flow to the inner ring gas channel of the gas stove burner through the first gas outlet channel 120, so that the gas can be burned at the inner ring gas channel of the gas stove burner; when the valve core 200 is rotated to make the air hole 210 communicate with the second air hole 131, the gas can flow to the inner ring gas channel of the gas stove burner through the second gas outlet channel 120, so that the gas can be burned at the inner ring gas channel of the gas stove burner; The channel 130 flows to the outer ring gas channel of the gas stove burner, so that the gas can be burned in the outer ring gas channel of the gas stove burner; when the valve core 200 is rotated to connect the air hole 210 with the first air hole 121 and the second air hole 131, the gas can flow to the inner ring gas channel of the gas stove burner through the first air outlet channel 120 and flow to the outer ring gas channel of the gas stove burner through the second air outlet channel 130, so that the gas can be burned in the inner ring gas channel and the outer ring gas channel of the gas stove burner.

[0045] Thus, by providing the air hole 210, it can communicate with both the first air hole 121 and the second air hole 131. Compared to independently providing the air hole 210 for communicating with the first air hole 121 and the air hole 210 for communicating with the second air hole 131 on the valve core 200, the air hole 210 can be easily processed and configured into any desired shape, and a sufficient sealing distance can be provided around the air hole 210. This not only facilitates the rational use of the space of the gas valve 1 and facilitates the reduction of the thickness of the valve body 100, thereby reducing the overall height of the gas valve 1, but also makes the flow curve of the gas valve 1 more linear, improves the heat adjustment performance of the inner and outer rings of the gas stove burner, and increases the rotation adjustment angle of the valve core 200, making it easier for users to obtain the desired heat when using the gas stove.

[0046] Therefore, the gas valve 1 according to the embodiment of the present invention has the advantages of a large rotation angle of the valve core 200 and good flow regulation linearity of the gas valve 1.

[0047] The following describes a gas valve 1 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0048] In some specific embodiments of the present invention, Figures 1-16 As shown, the gas valve 1 according to an embodiment of the present invention includes a valve body 100 and a valve core 200 .

[0049] Specifically, if Figure 15 As shown, the air hole 210 includes an inner hole section 214 and an outer hole section 215, which are connected in sequence along the radial direction of the valve core 200. The span of the outer hole section 215 along the circumference of the valve core 200 is greater than the span of the inner hole section 214 along the circumference of the valve core 200. The larger span of the outer hole section 215 along the circumference of the valve core 200 increases the maximum rotation angle of the valve core 200 for adjusting the flow rate. The smaller span of the inner hole section 214 along the circumference of the valve core 200 cooperates with the larger span of the outer hole section 215 along the circumference of the valve core 200 to improve the linear transformation of flow regulation and the continuity of flow rate changes. This facilitates changing the coordinated area of the air hole 210 and the first air vent 121 and / or the second air vent 131 during the rotation of the valve core 200, thereby changing the flow area of the gas, thereby adjusting the gas supply and making the flow curve of the gas valve 1 more linear.

[0050] Specifically, the inner hole section 214 may be a circular hole, and the outer hole section 215 may be a waist-shaped circular hole extending along the circumference of the valve core 200. The circular hole and waist-shaped circular hole structures are easier to process, and the waist-shaped circular hole extending along the circumference of the valve core 200 is easier to control the maximum rotation angle of the flow adjustment.

[0051] Optionally, the valve core 200 can rotate within an angle range of 0-225 degrees. By allowing the air hole 210 to communicate with the first air hole 121 and the second air hole 131, the valve core 200 can rotate within a range of 0-225 degrees. This can increase the rotation range of the valve core 200, facilitating more detailed adjustment of the heat of the gas stove burner to achieve the desired heat.

[0052] Of course, the rotatable angle of the valve core 200 can be 180 degrees, 220 degrees or 225 degrees.

[0053] In some embodiments, as Figure 15As shown, the air holes 210 include a first air hole 211, a second air hole 212, and a third air hole 213 arranged at intervals. The first air hole 211 is adapted to communicate with the first air hole 121, the second air hole 212 is adapted to communicate with the first air hole 121 and the second air hole 131, and the third air hole 213 is adapted to communicate with the first air hole 121. Thus, the valve core 200 can communicate with the inner ring gas channel of the gas stove burner through the first air hole 211, the second air hole 212, and the third air hole 213, and communicate with the outer ring gas channel of the gas stove burner through the second air hole 212, facilitating switching between the inner and outer rings of the gas stove burner and adjusting the heat.

[0054] Specifically, if Figure 15 As shown, in the axial direction of the valve core 200, the heights of the first air hole 211 and the third air hole 213 are higher than the height of the second air hole 212 (the vertical direction is as shown in FIG. Figure 15 As shown by arrow A in the figure). Thus, the second air holes 212 can be staggered with the first air holes 211 and the third air holes 213, which not only facilitates the design and processing of the shapes of the first air holes 211, the second air holes 212, and the third air holes 213, but also ensures that there is a sufficient sealing distance between the first air holes 211, the second air holes 212, and the third air holes 213.

[0055] Alternatively, as Figure 15 As shown, the first air hole 211, the second air hole 212 and the third air hole 213 are arranged adjacent to each other in the circumferential direction of the valve core 200, and the second air hole 212 is located between the first air hole 211 and the third air hole 213. This facilitates continuous change of firepower during the rotation of the valve core 200.

[0056] Specifically, if Figure 6 As shown, the first air vent 121 includes a first opening portion 122 and a second opening portion 123 that are connected in sequence along the extension direction of the accommodating chamber 101. The first opening portion 122 is adapted to be directly connected to the first air hole 211 or the third air hole 213, and the second opening portion 123 is adapted to be directly connected to the second air hole 212 or the third air hole 213. Because the heights of the first air hole 211 and the third air hole 213 are higher than the height of the second air hole 212, the first opening portion 122 and the second opening portion 123 can be arranged to correspond to the heights of the first air hole 211, the second air hole 212, and the third air hole 213, respectively. This allows for reliable communication between the first air vent 121 and the first, second, and third air holes 211, 212, and 213 during the rotation of the valve core 200, thereby regulating the flow of gas.

[0057] Alternatively, as Figure 6As shown, the first vent hole 121 is provided on the side wall of the accommodating cavity 101, and the first vent hole 121 is inclined along the thickness direction of the side wall of the accommodating cavity 101. This facilitates the reasonable arrangement of the air hole 210 and the first air outlet channel 120, making the structure of the gas valve 1 more reasonable and compact.

[0058] Specifically, in the circumferential direction of the accommodating cavity 101, the angle between the second vent hole 131 and the first vent hole 121 is less than or equal to 90 degrees, and in the axial direction of the accommodating cavity 101, the height of the first vent hole 121 is higher than the height of the second vent hole 131. Specifically, the second vent hole 131 can be located within a range of 90 degrees rotated clockwise from the first vent hole 121. This facilitates the coordination and communication between the second vent hole 131 and the second air hole 212. In some embodiments, as Figure 1 As shown, the air inlet of the air inlet channel 110, the air outlet of the first air outlet channel 120, and the air outlet of the second air outlet channel 130 are opened in the same direction, and the center lines of the air inlet channel 110, the first air outlet channel 120, and the second air outlet channel 130 are located in the same plane. This helps to reduce the length of the gas distribution pipe, making the structure of the gas stove more reasonable and compact, and improving the assembly of the gas stove.

[0059] Alternatively, as Figure 16 As shown, the valve body 100 further includes a gas storage chamber 140, which is connected between the air inlet channel 110 and the accommodating cavity 101. This allows the gas storage chamber 140 to have a pressure stabilizing effect, making the outlet pressure of the gas valve 1 more stable and not changing with changes in the inlet pressure.

[0060] Furthermore, the gas storage chamber 140 is provided with a guide bevel 141 adapted to guide the gas into the gas distribution cavity 201. Thus, the guide bevel 141 in the gas storage chamber 140, on the one hand, leaves a certain margin for the screw processing hole, on the other hand, facilitates demolding, and furthermore, the guide bevel has a smaller resistance to the gas, thereby reducing the pressure loss of the gas.

[0061] Specifically, the thickness of the valve body 100 is less than or equal to 18 mm. This not only reduces the material cost of the gas valve 1 but also facilitates its installation. Specifically, the gas valve 1 exhausts gas through the second outlet channel 130 of the valve body 100, utilizing the second air hole 212 of the valve core 200. The first air hole 211, the second air hole 212, and the third air hole 213 are staggered in the axial direction of the valve core 200, achieving efficient spatial utilization and reducing the overall height of the gas valve 1. The valve body 100 can be made very thin. The thinnest thickness is the diameter of a standard solenoid valve plus a certain wall thickness, which is also the maximum thickness of the valve body 100, and can be as thin as 18 mm.

[0062] In some specific embodiments, Figure 2 and Figure 3 As shown, the rotation angle of the valve core 200 is 0 degrees, that is, the valve core 200 does not rotate. At this time, the first gas outlet channel 120 and the second gas outlet channel 130 are both disconnected, and no gas passes through; Figure 4-Figure 6 As shown, the rotation angle of the valve core 200 is 40 degrees. At this time, the first air outlet channel 120 has already discharged air, and the second air outlet channel 130 is still disconnected; Figure 7 and Figure 8 As shown, the rotation angle of the valve core 200 is 90 degrees. At this time, the gas valve 1 is in the high fire position, that is, the fire power of the gas valve 1 is the largest, and the first gas outlet channel 120 and the second gas outlet channel 130 are both connected to the valve core 200 to discharge gas; Figures 9-11 As shown, the rotation angle of the valve core 200 is 170 degrees, at this time the first air outlet channel 120 is outlet, and the second air outlet channel 130 is in a disconnected state; Figure 12-14 As shown, the rotation angle of the gas valve 1 is 225 degrees. At this time, the gas valve 1 is in the low-fire position, i.e., the fire power of the gas valve 1 is the lowest, and only the first gas outlet channel 120 is used to discharge gas. The fire power of the minimum fire is determined by the low-fire aperture of the third gas hole 213. Of course, the angle of the low-fire position is not fixed and can be set arbitrarily. For example, the rotation angle of the gas valve 1 can be 225 degrees or 220 degrees.

[0063] Specifically, the valve stem of the gas valve 1 is rotated, thereby driving the valve core 200 to rotate. First, the first air hole 211 on the valve core 200 connects with the first air vent 121 on the valve body 100 to discharge gas. Then, the valve core 200 continues to rotate, and the second air hole 212 on the valve core 200 connects with the second air vent 131 on the valve body 100 to discharge gas. When the first air hole 211 on the valve core 200 and the first air vent 121 on the valve body 100 are about to be offset, the second air hole 212 on the valve core 200 connects with the first air vent 121 on the valve body 100 to discharge gas, thereby achieving the function of connecting the gas. At this time, gas is discharged from both the first gas outlet channel 120 and the second gas outlet channel 130 on the valve body 100. The valve core 200 then continues to rotate, disconnecting the second air hole 212 on the valve core 200 from the second air hole 131 on the valve body 100. This closes the outer ring gas channel of the gas stove burner, leaving only the inner ring gas channel to provide gas for combustion and ignition. At this point, the second air hole 131 on the valve body 100 can either utilize the third air hole 213 or not. The third air hole 213 functions as a low-flame hole. Using the third air hole 213 extends the range of the second outlet channel 130. Not utilizing the third air hole 213 reduces the range of the outer ring gas channel. Both options are feasible. The valve core 200 then continues to rotate. Just as the second air hole 212 on the valve core 200 is about to disconnect from the first air hole 121 on the valve body 100, the first air hole 121 reconnects to the third air hole 213 (the low-flame hole) on the valve core 200, enabling both ignition and minimum flame. The staggered layout of the holes of the valve core 200 cleverly realizes the connection transition with the first air outlet channel 120 and the second air outlet channel 130 of the valve body 100, making the flow regulation more linear.

[0064] According to a specific embodiment of the present invention, a gas valve 1 includes a valve body 100 and a valve core 200. The valve body 100 has a housing 101, an air inlet channel 110, a first air outlet channel 120, and a second air outlet channel 130. The first air outlet channel 120 is adapted to communicate with the inner ring gas channel of a gas stove burner and is in communication with the housing 101 through a first air vent 121. The second air outlet channel 130 is adapted to communicate with the outer ring gas channel of the gas stove burner and is in communication with the housing 101 through a second air vent 131. The valve core 200 is rotatably engaged within the housing 101. The valve core 200 has a sub-gas chamber 201 and an air passage 210 communicating with the sub-gas chamber 201. The air inlet channel 110 communicates with the sub-gas chamber 201. The air passage 210 selectively communicates with the first air vent 121 and / or the second air vent 131 when the valve core 200 rotates.

[0065] The air hole 210 includes an inner hole section 214 and an outer hole section 215, which are connected in the radial direction of the valve core 200. The opening area of the inner hole section 214 is smaller than that of the outer hole section 215. The valve core 200 can rotate within an angular range of 0-225 degrees. The air hole 210 includes a first air hole 211, a second air hole 212, and a third air hole 213, which are arranged in a spaced relationship. The first air hole 211 is adapted to communicate with the first air hole 121, the second air hole 212 is adapted to communicate with the first air hole 121 and the second air hole 131, and the third air hole 213 is adapted to communicate with the first air hole 121. In the axial direction of the valve core 200, the heights of the first air hole 211 and the third air hole 213 are higher than the height of the second air hole 212. The first air hole 211 , the second air hole 212 and the third air hole 213 are adjacently arranged in the circumferential direction of the valve core 200 , and the second air hole 212 is located between the first air hole 211 and the third air hole 213 .

[0066] The first vent 121 includes a first opening portion 122 and a second opening portion 123, which are connected in sequence along the extension direction of the accommodating chamber 101. The first opening portion 122 is adapted to communicate with the first air hole 211 or the third air hole 213, and the second opening portion 123 is adapted to communicate with the second air hole 212. The first vent 121 is inclined from the sidewall of the accommodating chamber 101 to the first air outlet channel 120. Around the circumference of the accommodating chamber 101, the first vent 121 is positioned adjacent to the second vent 131, and the height of the first vent 121 is higher than that of the second vent 131.

[0067] The air inlet of the air inlet channel 110 , the air outlet of the first air outlet channel 120 and the air outlet of the second air outlet channel 130 have the same opening direction, and the center lines of the air inlet channel 110 , the first air outlet channel 120 and the second air outlet channel 130 are located in the same plane.

[0068] The valve body 100 further includes a gas storage chamber connected between the air inlet channel 110 and the accommodating chamber 101. The gas storage chamber is provided with a guide slope suitable for guiding the gas to flow into the gas distribution chamber 201. The thickness of the valve body 100 is less than or equal to 18 mm.
