Detailed Implementation

[0027] In related technologies, pressure regulating valves and control valves are arranged separately. Some control valves have a certain pressure stabilization function, but the stabilization effect is limited and unstable under low pressure and low flow requirements. In addition, in related technologies, the air inlet and outlet are designed on opposite sides of the valve body. In a planar assembly arrangement, this can save space in terms of height. However, in a non-planar assembly arrangement, if the air outlet pipe needs to connect from the air outlet of the valve body to the air inlet of the burner located above or below the valve body, there is more space in terms of height. Designing the air inlet and outlet on the same side of the valve body can save space in front of and behind the valve body.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figures 1 to 4 The gas valve 100 according to an embodiment of the present utility model includes: a valve body 10, a shut-off mechanism 20, and an adjustment mechanism 30.

[0030] The valve body 10 includes a cavity 101, an inlet 1021, and an outlet 1022. The inlet 1021 allows gas to enter the gas valve 100. The cavity 101 guides the gas flow from the inlet 1021 to the outlet 1022. The outlet 1022 discharges gas from the gas valve 100 to its downstream pipeline. A shut-off mechanism 20 is connected to the valve body 10 and controls the opening and closing of the inlet 1021. A regulating mechanism 30 is connected to the valve body 10 and controls the flow rate at the outlet 1022. The shut-off mechanism 20 controls the on / off state of the gas valve 100. When the shut-off mechanism 20 is closed, gas cannot flow from the inlet 1021 to the cavity 101, and the gas valve 100 cuts off the gas flow. The regulating mechanism 30 controls the gas flow rate to adjust the cooking power of the gas cooking equipment, thereby adjusting the cooking temperature, cooking time, etc., as needed.

[0031] In addition, the gas valve 100 also includes a pressure regulating mechanism 40, which is connected to the valve body 10 and configured to regulate the fluid pressure within the control chamber 101. The pressure regulating mechanism 40 can be used to stabilize the gas pressure output by the gas valve 100, preventing insufficient gas pressure from affecting combustion and improving cooking stability.

[0032] According to the gas valve 100 of this embodiment, a pressure stabilizing mechanism 40 is added. Gas flows through the pressure stabilizing mechanism 40 before entering the regulating valve to control the gas flow rate, thus improving the pressure stabilizing performance of the valve body 10 and providing a more stable gas pressure under low-pressure combustion conditions. Furthermore, by connecting the shut-off mechanism 20, the pressure stabilizing mechanism 40, and the regulating mechanism 30 to the valve body 10, the shut-off valve and the regulating valve can be integrated, improving the integration level of the gas valve 100.

[0033] The gas valve 100 provided in this invention improves the stability of the output gas pressure by incorporating a pressure stabilizing mechanism 40. This is particularly suitable for scenarios requiring high gas pressure stability, such as gas ovens. Gas ovens use the flue gas generated by gas combustion to heat food, achieving a baking effect. Since the flue gas comes into contact with the food, the temperature requirement for the flue gas is relatively high. Therefore, in this case, setting up the pressure stabilizing mechanism 40 to stabilize the output gas pressure is especially important. Of course, the gas valve 100 in this invention can also be applied to other gas cooking scenarios.

[0034] like Figure 3 and Figure 4 In some embodiments, cavity 101 includes a shut-off cavity 103, a regulating cavity 104, and a pressure stabilizing cavity 105. Inlet 1021 is connected to shut-off cavity 103, regulating cavity 104 is connected to outlet 1022, shut-off mechanism 20 controls the opening and closing of shut-off cavity 103 and pressure stabilizing cavity 105, regulating mechanism 30 controls the flow rate and opening and closing between regulating cavity 104 and outlet, and pressure stabilizing mechanism 40 controls the pressure stabilization of fluid in pressure stabilizing cavity 105. The gas valve 100 can have a shut-off state, in which the shut-off chamber 103 and the pressure regulating chamber 105 are disconnected, and gas entering the shut-off chamber 103 cannot continue to flow into the pressure regulating chamber 105; the gas valve 100 can also have a connected state, in which the shut-off chamber 103 and the pressure regulating chamber 105 are connected, and the gas entering the shut-off chamber 103 will pass through the shut-off mechanism 20 and then enter the pressure regulating chamber 105, flowing towards the regulating chamber 104. When the regulating mechanism 30 controls the connection between the pressure regulating chamber 105 and the regulating chamber 104, the gas in the pressure regulating chamber 105 can flow... The gas enters the regulating chamber 104 and flows through the regulating chamber 104 to the outlet 1022, and can be discharged from the outlet 1022. Moreover, the regulating mechanism 30 can control the flow area between the stabilizing chamber 105 and the regulating chamber 104, thereby regulating the gas flow of the gas valve 100 to adjust the gas supply per unit time. The gas flow can be adjusted according to actual cooking requirements (cooking temperature, cooking time, etc.). When the regulating mechanism 30 controls the stabilizing chamber 105 and the regulating chamber 104 to disconnect, the gas in the stabilizing chamber 105 will not be able to enter the regulating chamber 104.

[0035] In addition, the pressure stabilizing mechanism 40 can improve the stability of gas pressure, thereby improving cooking efficiency and effectiveness. Furthermore, when the gas pressure entering through the inlet 1021 is relatively high, the pressure stabilizing mechanism 40 can also restrict the flow of gas from the cut-off chamber 103 to the regulating chamber 104, so as to maintain the gas pressure in the regulating chamber 104 and the outlet 1022, thereby improving the stability of the gas cooking equipment with the gas valve 100.

[0036] By setting the shut-off chamber 103 and the regulating chamber 104, the shut-off mechanism 20 can be matched with the shut-off chamber 103, and the regulating mechanism 30 can be matched with the regulating chamber 104. This allows the shut-off mechanism 20 to control the gas valve 100 to close, and the regulating mechanism 30 to adjust the flow rate of the gas valve 100. It also facilitates the sealing of the gas valve 100, thereby improving the stability and safety of the gas valve 100.

[0037] Optionally, the cavity 101 is distributed along a first direction, and the pressure stabilizing cavity 105 includes a first half 1051a, a second half 1051b, and a connecting port 1051c. At least a portion of the first half 1051a and at least a portion of the second half 1051b are distributed along a second direction. The connecting port 1051c extends along the second direction through the partition structure between the first half 1051a and the second half 1051b. The pressure stabilizing mechanism 40 is opposite to the connecting port 1051c and adjusts the connecting port 1051c according to the fluid pressure in the first half 1051a. When the pressure is higher than a preset pressure value, the connecting port 1051c is closed. The second direction is perpendicular to the first direction. By setting the first half 1051a and the second half 1051b, the pressure stabilizing mechanism 40 can be conveniently used to stabilize the pressure in the pressure stabilizing cavity 105, simplifying the structure of the gas valve 100 and improving the pressure stabilizing capability of the pressure stabilizing mechanism 40.

[0038] In this invention, the first direction can be referred to as the left-right direction in the accompanying drawings, the second direction as the up-down direction, and the third direction as the front-back direction. Of course, this is merely a description based on the accompanying drawings and is not intended to limit the scope of protection of this invention.

[0039] For example, such as Figure 2The pressure stabilizing mechanism 40 in this invention has the ability to stabilize pressure. The pressure stabilizing mechanism 40 may include a pressure stabilizing spring 41, a pressure stabilizing performance adjusting screw 42, a pressure stabilizing diaphragm 43, a pressure stabilizing adjusting core 44, and a pressure stabilizing outlet sealing gasket 45. Gas can reach the second half 1051b from the first half 1051a through the connecting port 1051c. One side of the pressure stabilizing diaphragm 43 contacts the gas, and the other side contacts the pressure stabilizing spring 41 and air. The pressure stabilizing adjusting core 44 is connected to the pressure stabilizing diaphragm 43 and placed on the gas side. When the gas pressure changes, the diaphragm generates different pressures. The change in the compression force of the pressure stabilizing spring 41 will cause it to expand and contract, causing the center height of the pressure stabilizing diaphragm 43 to change. The pressure stabilizing adjusting core 44 can move up and down with the pressure stabilizing diaphragm at the connecting port 1051c, controlling the opening of the connecting port 1051c, thereby adjusting and stabilizing the gas pressure in the second half 1051b.

[0040] Optionally, such as Figures 2 to 4 The valve body 10 includes a housing body 11, which has a first side and a second side opposite to each other along a second direction. The first side of the housing body 11 may be configured as an attachment. Figure 1 The upper part of the middle shell body 11 and the second side of the shell body 11 can be set as an attachment. Figure 1 The lower part of the main body 11 of the middle shell. The two ends of the voltage stabilizing cavity 105 are respectively provided with a first connecting part 1052 and a second connecting part 1053. The first connecting part 1052 can communicate with the cut-off cavity 103, and the second connecting part 1053 can communicate with the regulating cavity 104. Specifically, when the cut-off mechanism 20 is open, the first connecting part 1052 is connected to the cut-off cavity 103; when the cut-off mechanism 20 is closed, the first connecting part 1052 is disconnected from the cut-off cavity 103. When the regulating mechanism 30 is open, the second connecting part 1053 is connected to the regulating cavity 104; when the regulating mechanism 30 is closed, the second connecting part 1053 is disconnected from the regulating cavity 104. (See attached diagram) Figure 2 The left end of the voltage stabilizing cavity 105 is provided with a first connecting part 1052, and the right end of the voltage stabilizing cavity 105 is provided with a second connecting part 1053.

[0041] Optionally, at least a portion of the first connecting portion 1052 is disposed within the stop cavity 103, and at least a portion of the second connecting portion 1053 is disposed within the regulating cavity 104. This facilitates the use of the stop mechanism 20 to control the flow between the first connecting portion 1052 and the stop cavity 103, and the use of the regulating mechanism 30 to regulate the flow rate between the second connecting portion 1053 and the regulating cavity 104.

[0042] To facilitate the integral molding of the shell body 11, in this utility model, the stop cavity 103, the first connecting portion 1052, the adjusting cavity 104, and the second connecting portion 1053 extend along the second direction and penetrate the first side portion and / or the second side portion; the first half portion 1051a connects to the first connecting portion 1052 and penetrates the second side portion, and the second half portion 1051b connects to the second connecting portion 1053 and penetrates the first side portion. This facilitates the integral molding of the shell body 11, which can be formed by injection molding or other methods, improving the molding efficiency, structural strength, and stability of the gas valve 100.

[0043] For example, the stop cavity 103 extends along the second direction and penetrates the first side portion; the first connecting portion 1052 extends along the second direction and penetrates the first and second sides; the adjustment cavity 104 extends along the second direction and penetrates the second side portion; the second connecting portion 1053 extends along the second direction and penetrates the first and second sides; the first half 1051a connects to the first connecting portion 1052 and penetrates the second side portion; the second half 1051b connects to the second connecting portion 1053 and penetrates the first side portion. A parting surface can be formed at the middle position of the shell body 11 along a third direction to facilitate the integral molding of the shell body 11.

[0044] A connecting hole is provided between the second half 1051b and the second side portion. The connecting hole extends along the first direction and connects the second half 1051b and the second side portion. In order to facilitate the formation of the connecting hole, a hole can be drilled on the outer side of the second side portion, and the connecting hole is formed between the second half 1051b and the second side portion. Then the drilled hole on the outer side of the second side portion is sealed.

[0045] Alternatively, the aforementioned inlet 1021 and outlet 1022 can be formed by drilling.

[0046] Optionally, the valve body 10 further includes a first cover plate 121 and a second cover plate 122. The first cover plate 121 covers the first side of the housing body 11, and the second cover plate 122 covers the second side of the housing body 11. The first cover plate 121 and the second cover plate 122 can be used to seal both sides of the housing body 11, so as to form a closed chamber inside the housing body 11 and facilitate the assembly of the valve body 10, the shut-off mechanism 20, the pressure stabilizing mechanism 40, and the adjusting mechanism 30. In addition, the first cover plate 121 may include multiple first mounting plates arranged separately, respectively opposite to the shut-off mechanism 20, the pressure stabilizing mechanism 40, and the adjusting mechanism 30. Of course, the first cover plate 121 can also be a one-piece plate structure. Similarly, the second cover plate 122 can be multiple second mounting plates arranged separately, or it can be a one-piece plate structure.

[0047] Optionally, the shut-off mechanism 20, the pressure stabilizing mechanism 40, and the regulating mechanism 30 are installed on the first side, which can facilitate the installation of the shut-off mechanism 20, the pressure stabilizing mechanism 40, and the regulating mechanism 30, simplify the assembly of the gas valve 100, improve the stability of the gas valve 100, and facilitate maintenance.

[0048] In some embodiments, at least a portion of the shut-off mechanism 20 is opposite to the first connecting portion 1052 along the second direction, and at least a portion of the adjusting mechanism 30 is opposite to the second connecting portion 1053 along the second direction. This can optimize the performance of the gas valve 100.

[0049] like Figure 2 In some embodiments, the first end of the pressure regulating chamber 105 is provided with a first connecting portion 1052. The shut-off mechanism 20 includes a first driving portion 21 and a first valve core portion 22. The first valve core portion 22 is disposed in the shut-off chamber 103 and opposite to the first connecting portion 1052. The first driving portion 21 drives the first valve core portion 22 to move to open and close the first connecting portion 1052. When the first connecting portion 1052 is open, it communicates with the shut-off chamber 103. When the first connecting portion 1052 is closed, it is disconnected from the shut-off chamber 103. Through the cooperation of the first connecting portion 1052 and the shut-off chamber 103, the first valve core portion 22 can be conveniently used to open and close the first connecting portion 1052, simplifying the structure of the gas valve 100 and facilitating control. Specifically, the first connecting portion 1052 may be provided with a first opening 1031, and the first valve core portion 22 is disposed in the shut-off chamber 103 and opposite to the first opening 1031.

[0050] like Figure 2 Optionally, the valve body 10 also has a first mounting port 1032, which is opposite to the first communicating portion 1052. The first driving portion 21 is mounted on the outside of the valve body 10 and extends into the first mounting port 1032 to connect with the first valve core portion 22. By providing the first mounting port 1032, the first driving portion 21 can be easily installed, achieving stable installation of the first driving portion 21 and the valve body 10, and facilitating the first driving portion 21 to drive the first valve core portion 22 to move. In addition, a first sealing element is provided between the first driving portion 21 and the periphery of the first mounting port 1032. The first sealing element can be used to seal the gap between the first driving portion 21 and the periphery of the first mounting port 1032, improving the sealing performance of the gas valve 100.

[0051] like Figure 1As shown, the valve body 10 may include a housing body 11 and a shut-off mounting plate 1211 (or, in other words, the first cover plate 121 includes the shut-off mounting plate 1211). The pressure stabilizing chamber 105 is arranged in the left-right direction, the first connecting portion 1052 is arranged in the up-down direction, and the inlet 1021 is arranged in the front-back direction. The pressure stabilizing chamber 105 includes a connecting groove 1051 and a first connecting portion 1052, wherein the connecting groove 1051 extends in the left-right direction, and the first connecting portion 1052 communicates with the connecting groove 1051. To facilitate the integral molding of the housing body 11, the first connecting portion 1052 and the shut-off chamber 103 may be arranged to extend in the up-down direction and penetrate through the upper end and / or lower end of the housing body 11.

[0052] For example, the first connecting portion 1052 extends vertically and its upper end penetrates the upper end of the shell body 11 to form a first opening 1031. The shut-off cavity 103 extends vertically and its upper end penetrates the upper end of the shell body 11 to form a first mounting port 1032. The first opening 1031 is located inside the shut-off cavity 103. The shut-off mounting plate 1211 covers the upper end of the shell body 11 and seals the first mounting port 1032. The shut-off mounting plate 1211 and the first opening 1031 are spaced apart. The first valve core 22 is located between the first opening 1031 and the shut-off mounting plate 1211. The opening and closing of the first opening 1031 are achieved by the vertical movement of the first valve core 22. The first driving portion 21 can be connected to the shut-off mounting plate 1211.

[0053] like Figure 2 In some embodiments, the second end of the pressure regulating chamber 105 is provided with a second connecting portion 1053. The adjusting mechanism 30 includes a second driving portion 31 and a second valve core portion 32. The second valve core portion 32 is disposed in the adjusting chamber 104 and is opposite to the second connecting portion 1053. The second driving portion 31 drives the second valve core portion 32 to move to adjust the opening degree of the second connecting portion 1053. When the second connecting portion 1053 is open, it communicates with the adjusting chamber 104. Through the cooperation of the second connecting portion 1053 and the adjusting chamber 104, the opening degree of the first connecting portion 1052 can be easily adjusted using the second valve core portion 32, simplifying the structure of the gas valve 100 and facilitating control. Specifically, the second connecting portion 1053 can be provided with a second opening 1041. The second valve core portion 32 is disposed in the adjusting chamber 104 and is opposite to the second opening 1041. The second valve core portion 32 can move along the axial direction of the second opening 1041 to adjust the opening of the second connecting portion 1053, thereby realizing the adjustment of the gas flow rate of the gas valve 100.

[0054] The valve body 10 also has a second mounting port 1042. The second mounting port 1042 and the second connecting portion 1053 are distributed axially along the second connecting portion 1053. By providing the second mounting port 1042, the second drive unit 31 can be easily installed, achieving stable installation of the second drive unit 31 and the valve body 10, and facilitating the second drive unit 31 to drive the second valve core 32 to move. The adjusting mechanism 30 also includes a second sealing member 33, which is connected to the periphery of the second valve core and the second mounting port 1042 respectively to seal the second mounting port 1042. The second sealing member 33 can be used to seal the second mounting port 1042, improving the sealing performance of the gas valve 100.

[0055] The second drive unit 31 is mounted on the outside of the valve body 10 and is electromagnetically driven with the second valve core 32. The electromagnetic force can be used to drive the second valve core 32 to move, thereby improving the sealing performance of the gas valve 100.

[0056] Combination Figure 1 and Figure 2 The valve body 10 may include a housing body 11 and an adjusting mounting plate 1212 (or the first cover plate 121 includes the adjusting mounting plate 1212). The pressure stabilizing chamber 105 is arranged in the left-right direction, the second connecting portion 1053 is arranged in the up-down direction, and the outlet 1022 is arranged in the front-back direction. The pressure stabilizing chamber 105 includes a connecting groove 1051 and a second connecting portion 1053, wherein the connecting groove 1051 extends in the left-right direction, and the second connecting portion 1053 connects to the right end of the connecting groove 1051 and communicates with the connecting groove 1051. To facilitate the integral molding of the housing body 11, the second connecting portion 1053 and the adjusting chamber 104 may be arranged to extend in the up-down direction and penetrate through the upper end and / or lower end of the housing body 11.

[0057] For example, the second connecting portion 1053 extends vertically, with its upper end penetrating the upper end of the housing body 11 and forming a second mounting port 1042. The second valve core 32 is movably inserted into the second connecting portion 1053 in the vertical direction. A second sealing member 33 connects the upper part of the second valve core 32 and the periphery of the second mounting port 1042 to close the second mounting port 1042. Additionally, an adjusting mounting plate 1212 covers the second mounting port 1042. The lower end of the second connecting portion 1053 penetrates the lower end of the housing body 11 and forms a second opening 1041. A third sealing member is provided at the lower end of the second valve core 32. The second valve core 32 can be moved vertically to close and open the second opening 1041, and the opening degree of the second connecting portion 1053 can be adjusted by adjusting the distance between the third sealing member and the periphery of the second opening 1041. The adjustment cavity 104 extends vertically and penetrates the lower end of the shell body 11. The second opening 1041 is located inside the adjustment cavity 104. The second cover plate 122 covers and closes the lower end of the adjustment cavity 104. The second cover plate 122 is spaced apart from the second opening 1041. The second valve core 32 is located between the second opening 1041 and the second cover plate 122. The opening degree of the second opening 1041 is adjusted by moving the second valve core 32 vertically. The second drive unit 31 is connected to the adjustment mounting plate 1212.

[0058] In addition, the first cover plate 121 may also include a voltage stabilizing mounting plate 1213, to which the voltage stabilizing mechanism 40 is connected.

[0059] Combination Figures 1 to 4 In some embodiments, the intake section of inlet 1021 is elliptical, which allows for circumferential limiting during intake pipe connection, improving connection stability. Optionally, the inner side of the circumferential wall of the intake section of inlet 1021 is provided with a recessed platform structure. This platform structure can limit the connection during intake pipe connection, making assembly more convenient. When the intake pipe connects to inlet 1021, a sealing gasket can be placed on the recessed platform structure. The end of the intake pipe is provided with a flange, the shape and size of which are adapted to the shape and size of the recessed platform structure. The flange can be located inside the recessed platform structure and abuts against the sealing gasket along the axial direction, thereby achieving a seal between the intake pipe joint and inlet 1021 using the sealing gasket. The inner periphery of the recessed platform structure can be non-circular, facilitating intake pipe installation, improving the stability of intake pipe installation, and preventing mistaken connection. In addition, the flange can be provided with a first mounting hole, and the gas valve 100 can be provided with a second mounting hole. Bolts and other fasteners can be used to pass through the first and second mounting holes to achieve a stable connection between the end of the air inlet pipe and the gas valve 100.

[0060] In addition, the outlet 1022 can be designed as a cylindrical structure, wherein the inner wall of the cylindrical structure can be designed as a smooth wall surface to facilitate the connection between the air outlet pipe and the outlet 1022 and improve assembly efficiency. Furthermore, the end periphery of the outlet 1022 is provided with a chamfer or rounding to facilitate the sealing ring to slide into the cylinder when the air outlet is connected.

[0061] In addition, the cut-off mechanism 20 of this utility model is an electromagnetic drive mechanism, in which a coil is provided, and it can be configured to open the air passage when the coil is energized and close the air passage when the coil is de-energized.

[0062] The regulating mechanism 30 of this utility model can also be set as an electromagnetic drive mechanism, in which an regulating coil is provided, and the size of the gas passage cross section can be controlled by controlling the current of the regulating coil, thereby realizing the regulation of the gas flow rate.

[0063] In some embodiments, the valve body 10 is constructed as an integral structure, which can improve the integration of the gas valve 100, reduce the space occupied by the gas valve 100, and facilitate the installation, use and maintenance of the gas valve 100.

[0064] Of course, the valve body 10 in this utility model can also be configured as a split structure. For example, the valve body 10 can be configured as a main body and a mounting structure that are split, with the inlet 1021, outlet 1022 and cavity 101 located in the main body, and the shut-off mechanism 20 and adjusting mechanism 30 located in the mounting structure. The above description is only some embodiments of this utility model and is not intended to limit the scope of protection of this utility model.

[0065] like Figure 1 and Figure 3 The inlet 1021 and outlet 1022 are located on the same side of the valve body 10, saving assembly space before and after the valve body 10. Specifically, when the inlet 1021 and outlet 1022 are located on different sides of the valve body 10, the intake pipe connecting to the inlet 1021 and the outlet pipe connecting to the outlet 1022 are connected to different sides of the gas valve 100, occupying space on different sides of the gas valve 100. Since the space occupied by the intake or outlet pipe is limited, the space on their sides is wasted. Especially when the inlet 1021 and outlet 1022 are located on opposite sides of the valve body 10, the space occupied by the intake and outlet pipes is limited, and a large amount of space on the sides is wasted, affecting space utilization. This utility model places the inlet 1021 and outlet 1022 on the same side of the valve body 10. The air inlet pipe connected to the inlet 1021 and the air outlet pipe connected to the outlet 1022 can be connected to the same side of the gas valve 100. In this way, the air inlet pipe and the air outlet pipe will occupy the space on the same side of the gas valve 100, which can make full use of the space on the side of the air inlet pipe or the side of the air outlet pipe, thereby reducing the space occupation and improving the space utilization rate.

[0066] In addition, such as Figure 1 The shut-off mechanism 20 and the regulating mechanism 30 are installed on the same side of the valve body 10, which saves assembly space for the valve body 10. Specifically, when the shut-off mechanism 20 and the regulating mechanism 30 are on different sides of the valve body 10, the shut-off mechanism 20 and the regulating mechanism 30 will occupy space on different sides of the gas valve 100, and the space occupied by the shut-off mechanism 20 or the regulating mechanism 30 is limited, and the space on their sides is wasted. Especially when the shut-off mechanism 20 and the regulating mechanism 30 are located on opposite sides of the valve body 10, the space occupied by the shut-off mechanism 20 and the regulating mechanism 30 is limited, and a large amount of space on the sides is wasted, affecting the space utilization rate. This utility model, by placing the shut-off mechanism 20 and the regulating mechanism 30 on the same side of the valve body 10, will not occupy the space on the same side of the gas valve 100, and can make full use of the space on the side of the shut-off mechanism 20 and the regulating mechanism 30, thereby reducing the space occupation and improving the space utilization rate.

[0067] In addition, by placing the shut-off mechanism 20 and the regulating mechanism 30 on the same side of the valve body 10, when maintenance of the gas valve 100 is required, it is only necessary to observe or detect the working status of the gas valve 100 from the side of the gas cooking equipment on which the gas valve 100 is installed. This facilitates the assembly and maintenance of the gas valve 100 and improves the stability and service life of the gas valve 100.

[0068] The gas cooking appliance according to an embodiment of the present invention includes the aforementioned gas valve 100.

[0069] In addition, gas cooking equipment may also include a gas outlet pipe with outlet 1022.

[0070] The outlet 1022 of the gas valve 100 adopts a quick-connect structure, and the gas outlet pipe can be plugged in to greatly improve the assembly efficiency. This connection method is suitable for the arrangement structure where the assembly space is small and it is not easy to tighten the nut. The inlet 1021 and outlet 1022 of the gas valve 100 are designed on the same side, and the inlet pipe and outlet pipe are connected on the same side, reducing the space occupied in front of the valve body 10.

[0071] In some embodiments, a sealing ring is provided between the outer circumferential surface of the gas outlet pipe and the inner circumferential surface of the outlet 1022. The outer circumferential diameter of the gas outlet pipe is smaller than the inner circumferential diameter of the outlet 1022, and the difference between the inner circumferential diameter of the outlet 1022 and the outer circumferential diameter of the gas outlet pipe is less than twice the diameter of the sealing ring. This allows for a quick-connect connection between the gas outlet pipe and the gas valve 100, improving the connection stability and sealing performance. Specifically, the outer diameter of the gas outlet pipe is smaller than the inner diameter of the outlet 1022. The gas outlet pipe is fitted with a sealing ring and inserted into the outlet 1022. The gap between the inner circumferential surface of the outlet 1022 and the gas pipe is smaller than the diameter of the sealing ring. Compression of the sealing ring achieves a sealing effect. The inner wall edge of the outlet 1022 has a chamfer to facilitate the sliding of the sealing ring into the outlet 1022 during the connection of the gas outlet pipe.

[0072] The outlet pipe can be configured to include a pipe body and a limiting part, the limiting part being connected to the pipe body along the axial direction, and the limiting part protruding from the outer peripheral surface of the pipe body; the outlet 1022 includes a first section located upstream and a second section located downstream along the outlet direction, the radial dimension of the first section is smaller than the radial dimension of the second section, and a step is constructed at the connection between the first section and the second section, and the edge of the outlet 1022 is rounded or chamfered, or in other words, the peripheral edge of the outlet 1022 end of the second section is rounded or chamfered.

[0073] When installing the vent pipe, a sealing ring can be fitted onto the pipe body, and the end of the pipe body can be inserted into the outlet 1022. The end of the pipe body can be quickly inserted. The radial dimension of the limiting part is smaller than the radial dimension of the first section but larger than the radial dimension of the second section. The radial dimension of the sealing ring is smaller than the radial dimension of the second section, larger than the radial dimension of the first section, and smaller than the radial dimension of the second section after the edge is rounded or chamfered. In this way, when the vent pipe is inserted into the outlet 1022, the limiting part and the rounded or chamfered structure can push the sealing ring into the second section. The sealing ring can also enter the outlet 1022 and seal with the inner circumferential surface of the outlet 1022. The limiting part also limits the vent pipe.

[0074] In addition, the aforementioned radial dimension refers to the dimension perpendicular to the axis. For example, the radial dimension of outlet 1022 refers to the maximum dimension of the inner circumferential surface of outlet 1022 in the direction perpendicular to the axis of outlet 1022. When the axis of outlet 1022 extends in the front-back direction, the radial dimension of outlet 1022 may include the maximum dimension of outlet 1022 in the up-down direction, the maximum dimension of outlet 1022 in the left-right direction, etc.

[0075] The radial dimension of the limiting part is greater than the radial dimension of the first segment and less than the radial dimension of the second segment, including: the maximum dimension of the limiting part in the vertical direction is greater than the maximum dimension of the first segment in the vertical direction and less than the maximum dimension of the second segment in the vertical direction; the maximum dimension of the limiting part in the horizontal direction is greater than the maximum dimension of the first segment in the horizontal direction and less than the maximum dimension of the second segment in the horizontal direction, etc. Wherein, when the tube body and outlet 1022 are circular, the radial dimension of the tube body is the outer diameter of the tube body, and the radial dimension of the outlet 1022 is the inner diameter of the outlet 1022. When the tube body and outlet 1022 are not circular, the radial dimension refers to the dimension of the corresponding position of the tube body and outlet 1022 in the direction perpendicular to the axis of the outlet 1022.
