Description

Technical Field

[0001] This utility model relates to a gas valve and belongs to the field of gas valve technology. Background Technology

[0002] The gas valve is an important component of a gas stove, primarily used to control the gas supply and regulate the gas flow. There are two main types of gas valves used in existing gas stoves: one with a single gas outlet, which has the advantage of easy adjustment of flame intensity but the disadvantage of insufficient flame strength; and another with dual gas outlets (such as...). Figure 1 The advantage is that the firepower is strong enough, but the disadvantage is that the firepower is not easy to adjust.

[0003] Regarding the existing dual-exit gas valve structure (such as...) Figure 2 The reason why the firepower is difficult to adjust is mainly due to the following: when the valve is turned, the valve core is in one of the following positions: 0 degrees, 90 degrees, 130 degrees, and 180 degrees (e.g., ...). Figure 3-6 Based on the size and connection sequence of the valve core's inlet and outlet ports and the inlet and outlet channels, create a diagram showing the firepower and firing sequence of outlet channel I and outlet channel II (e.g., Figure 7 ).from Figure 7 It can be observed that when the valve core is opened to 90 degrees, gas outlet channel I is in low flame mode, but when it is opened to 130 degrees, both gas outlet channel I and gas outlet channel II are in medium flame mode, and when it is opened to 180 degrees, both gas outlet channel I and gas outlet channel II are in high flame mode. When using the stove to adjust from low flame to medium flame, it is immediately adjusted to two medium flames; when adjusting to high flame, it is also immediately adjusted to two high flames. It is difficult to adjust a single medium flame and a single high flame during the process of adjusting the firepower.

[0004] Therefore, the research objective of this utility model is to provide a gas valve that allows for easy adjustment of the firepower and provides sufficient firepower. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this utility model provides a gas valve that uses a synchronously rotating double-ball valve core to regulate the gas flow in the dual gas outlet channels. Before the flame in the first gas outlet channel reaches high flame, the second gas outlet channel remains closed. Only after the flame in the first gas outlet channel reaches high flame and is rotated a certain angle, does the second gas outlet channel open and reach high flame, thus achieving a dual high flame state.

[0006] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows: A gas valve includes a valve body, a first valve core, and a second valve core. The valve body has an inlet channel, a first outlet channel, and a second outlet channel. A valve core cavity is provided between the inlet channel, the first outlet channel, and the second outlet channel. The first valve core and the second valve core are rotatably disposed in the valve core cavity and are connected. The first valve core connects or blocks the inlet channel and the first outlet channel, and the second valve core connects or blocks the inlet channel and the second outlet channel.

[0007] Furthermore, the first valve core has a first vent hole axially located in the middle, and the second valve core has a second vent hole axially located in the middle. One end of the second vent hole is connected to the first vent hole, and the other end is connected to the first vent channel. The first valve core has a first inlet hole radially located on one side. One end of the first inlet hole is connected to the first vent hole, and the other end is connected to the inlet channel. The side wall of the first valve core also has an inlet groove circumferentially connected to the first inlet hole. The inlet groove gradually decreases in size from the end near the first inlet hole to the end away from the first inlet hole. The second valve core has a third vent hole radially located on one side. One end of the third vent hole is connected to the second vent hole, and the other end is connected to the second vent channel. The third vent hole can only be connected to the second vent channel when the first inlet hole is connected to the inlet channel.

[0008] Furthermore, the first valve core has a first vent hole axially located in the middle, and the second valve core has a second vent hole axially located in the middle. One end of the second vent hole is connected to the first vent hole, and the other end is connected to the first vent channel. The first valve core has a second, third, and fourth vent hole radially arranged on one side. The diameter of the fourth vent hole is larger than the diameter of the third vent hole, which is larger than the diameter of the second vent hole. One end of each of the second, third, and fourth vent holes is connected to the first vent hole, and the other end can be connected to the vent channel. The second valve core has a third vent hole radially located on one side. One end of the third vent hole is connected to the second vent hole, and the other end can be connected to the second vent channel. The third vent hole can only be connected to the second vent channel when the fourth vent hole is connected to the vent channel.

[0009] Furthermore, the first valve core has a first retaining shaft at one end near the second valve core and a first retaining groove at the other end. The second valve core has a second retaining groove at one end near the first valve core that matches the first retaining shaft. The first valve core is fixedly connected to the second valve core by inserting the first retaining shaft into the second retaining groove.

[0010] Furthermore, a connecting rod is fixedly connected to the end of the first valve core away from the second valve core. One end of the connecting rod is provided with a second retaining shaft that matches the first retaining groove, and the other end is provided with a third retaining groove. The connecting rod is fixedly connected to the first valve core by inserting the second retaining shaft into the first retaining groove.

[0011] Furthermore, it also includes an ignition assembly, which includes a base, a rotating shaft, an ignition lever, a spring, and a pressure cap. The base is fixed to the side of the valve body near the connecting rod. The rotating shaft is movably mounted on the base. One end of the rotating shaft is provided with a locking plate that matches the third locking slot. A child lock is fixed to the locking plate. The other end of the rotating shaft extends to the outside of the base. The ignition lever is fixed to the connecting rod. The spring is sleeved on the connecting rod and is located between the ignition lever and the child lock. The pressure cap is fixed to the end of the rotating shaft that extends to the outside of the base.

[0012] Furthermore, it also includes a solenoid valve and a solenoid valve pin. The valve body is also provided with a pin cavity and a solenoid valve cavity that communicate with the air intake channel. The solenoid valve is located in the solenoid valve cavity, and the solenoid valve pin is movably located in the pin cavity. One end of the solenoid valve pin extends to the trigger end of the solenoid valve, and the other end extends to the trigger end of the pressure cap.

[0013] Furthermore, a sleeve is provided at the end of the ejector pin cavity away from the solenoid valve cavity, the solenoid valve ejector pin is movably mounted on the sleeve, and an elastic element is provided inside the sleeve to push the solenoid valve ejector pin to reset.

[0014] Furthermore, it also includes an air inlet, which is located on the valve body, and the bottom of the air inlet is connected to the solenoid valve cavity.

[0015] Furthermore, it also includes a valve cover, which is fixed to the side of the valve body near the second air outlet channel, and the air outlet end of the second air outlet channel extends to the outside of the valve cover.

[0016] The beneficial effects of this utility model are: 1. The gas flow rate of the dual gas outlet channels is adjusted by the synchronously rotating double ball valve core. Before the flame of the first gas outlet channel reaches high heat, the second gas outlet channel remains closed. Only after the flame of the first gas outlet channel reaches high heat and is rotated a certain angle does the second gas outlet channel open and reach high heat, thus achieving a powerful dual-flame state. This combines the advantages of easy flame adjustment of a single gas outlet channel with the sufficient flame of a dual gas outlet channel. 2. The flame increases linearly from low to high and then to high heat, making it easier to adjust when using the stove. Attached Figure Description

Detailed Implementation

[0052] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 8-34 Further analysis of this utility model is then conducted. Example

[0053] like Figure 8-27 As shown, a gas valve includes a valve body 10, a first valve core 20, and a second valve core 30. The valve body 10 has an inlet channel 11, a first outlet channel 12, and a second outlet channel 13. A valve core cavity 14 is provided between the inlet channel 11, the first outlet channel 12, and the second outlet channel 13. The first valve core 20 and the second valve core 30 are rotatably disposed in the valve core cavity 14 and are connected to achieve synchronous rotation of the first valve core 20 and the second valve core 30. The first valve core 20 connects or blocks the inlet channel 11 and the first outlet channel 12, and the second valve core 30 connects or blocks the inlet channel 11 and the second outlet channel 13.

[0054] Specifically, the first valve core 20 has a first vent hole 21 axially located at its center, and the second valve core 30 has a second vent hole 31 axially located at its center. One end of the second vent hole 31 is connected to the first vent hole 21, and the other end is connected to the first vent channel 12. The first valve core 20 has a first inlet hole 22 radially located on one side. One end of the first inlet hole 22 is connected to the first vent hole 21, and the other end is connected to the inlet channel 11. The sidewall of the first valve core 20 also has a vent hole 22 circumferentially located along its side. The first air inlet 22 is connected to the air inlet groove 23, and the air inlet groove 23 is set to gradually decrease in size from the end near the first air inlet 22 to the end away from the first air inlet 22. The second valve core 30 is provided with a third air outlet 32 ​​radially on one side. One end of the third air outlet 32 ​​is connected to the second air outlet 31, and the other end can be connected to the second air outlet channel 13. The third air outlet 32 ​​can only be connected to the second air outlet channel 13 when the first air inlet 22 is connected to the air inlet channel 11.

[0055] When the first valve core 20 is rotated to 90 degrees to open the gas supply, the smaller end of the air inlet groove 23 first connects with the air inlet channel 11. At this time, the communication surface between the air inlet channel 11 and the first air inlet hole 22 is small, the gas flow into the first air outlet hole 21 is small, and the first air outlet channel 12 is in a low flame state. The gas flows from the air inlet channel 11 through the air inlet groove 23 and the first air inlet hole 22 into the first air outlet hole 21, and then flows through the first air outlet hole 21 and the second air outlet hole 31 to the first air outlet channel 12, and is output to the stove. Continue to rotate the first valve core 20 to 13 degrees. At 0 degrees, the middle end of the intake groove 23 is connected to the intake channel 11. At this time, the connection surface between the intake channel 11 and the first intake hole 22 increases by 90 degrees, and the gas flow into the first outlet hole 21 also increases relatively. The first outlet channel 12 is in a medium-fire state. When the first valve core 20 is rotated to 180 degrees, the larger end of the intake groove 23 is connected to the intake channel 11. At this time, the connection surface between the intake channel 11 and the first intake hole 22 is large, and the gas flow into the first outlet hole 21 is large. The first outlet channel 12 is in a high-fire state. During the above process, although the second valve core 30 rotates synchronously with the first valve core 20, the third outlet hole 32 fails to rotate to connect with the second outlet channel 13. Therefore, the second outlet channel 13 remains in the off-fire state. When the first valve core 20 is rotated to 210 degrees, the first air inlet 22 is connected to the air inlet channel 11, and at the same time, the second valve core 30 is rotated to the third air outlet 32, which is connected to the second air outlet channel 13. After the gas flows into the second air outlet 31, it flows to the first air outlet channel 12 and also to the second air outlet channel 13 through the third air outlet 32. At this time, both the first air outlet channel 12 and the second air outlet channel 13 are in a high flame state, so that the stove reaches a double high flame state.

[0056] In this embodiment, preferably, the first valve core 20 is provided with a first retaining shaft 27 at one end near the second valve core 30 and a first retaining groove 28 at the other end. The second valve core 30 is provided with a second retaining groove 33 that matches the first retaining shaft 27 at one end near the first valve core 20. The first valve core 20 is fixedly connected to the second valve core 30 by inserting the first retaining shaft 27 into the second retaining groove 33.

[0057] In this embodiment, preferably, a connecting rod 40 is fixedly connected to the end of the first valve core 20 away from the second valve core 30. One end of the connecting rod 40 is provided with a second retaining shaft 41 that matches the first retaining groove 28, and the other end is provided with a third retaining groove 42. The connecting rod 40 is fixedly connected to the first valve core 20 by inserting the second retaining shaft 41 into the first retaining groove 28.

[0058] In this embodiment, preferably, it further includes an ignition assembly 50, which includes a base 51, a rotating shaft 52, an ignition paddle 53, a spring 54, and a pressure cap 55. The base 51 is fixed to the side of the valve body 10 near the connecting rod 40. The rotating shaft 52 is movably mounted on the base 51. One end of the rotating shaft 52 is provided with a locking plate 521 that matches the third locking slot 42. When igniting, the locking plate 521 of the rotating shaft 52 is inserted into the third locking slot 42 to achieve a movable connection with the connecting rod 40, and drives the connecting rod 40 to rotate synchronously with the rotating shaft 52. A child lock 56 is fixedly mounted on the locking plate 521. The other end of the rotating shaft 52 extends to the outside of the base 51. The ignition paddle 53 is fixedly mounted on the connecting rod 40. The spring 54 is sleeved on the connecting rod 40 and is located between the ignition paddle 53 and the child lock 56. The pressure cap 55 is fixedly mounted to the end of the rotating shaft 52 that extends to the outside of the base 51.

[0059] When igniting, press down on the pivot 52 to disengage the child lock 56 from the locking groove in the valve body 10, then rotate the pivot 52. As the pivot 52 rotates, it drives the connecting rod 40 to rotate synchronously, causing the ignition paddle 53 to rotate and ignite. Simultaneously, the connecting rod 40 drives the first valve core 20 and the second valve core 30 to rotate synchronously, allowing gas to pass through. After ignition, release the pivot 52, and the spring 54 will push the pivot 52 back to its original position.

[0060] In this embodiment, preferably, it also includes a solenoid valve 60 and a solenoid valve pin 70. The valve body 10 is further provided with a pin cavity 15 and a solenoid valve cavity 16 that communicate with the air intake channel 11. The solenoid valve 60 is disposed in the solenoid valve cavity 16, and the solenoid valve pin 70 is movably disposed in the pin cavity 15. One end of the solenoid valve pin 70 extends to the trigger end of the solenoid valve 60, and the other end extends to the trigger end of the pressure cap 55.

[0061] When igniting, press the pivot 52 to press down the pressure cap 55, which pushes the solenoid valve pin 70 to move towards the solenoid valve 60, triggering the solenoid valve 60 to open and allow gas to flow from the solenoid valve chamber 16 through the pin chamber 15 into the air intake channel 11.

[0062] In this embodiment, preferably, a sleeve 80 is provided at the end of the ejector pin cavity 15 away from the solenoid valve cavity 16, the solenoid valve ejector pin 70 is movably disposed on the sleeve 80, and an elastic element is provided inside the sleeve 80 to push the solenoid valve ejector pin 70 to reset. The elastic element can be a spring or a sheet.

[0063] In this embodiment, preferably, it also includes an air inlet 17, which is provided on the valve body 10. The bottom of the air inlet 17 is connected to the solenoid valve cavity 16, and external gas enters the valve body 10 through the air inlet 17.

[0064] In this embodiment, preferably, it also includes a valve cover 90, which is fixed to the side of the valve body 10 near the second air outlet channel 13, and the air outlet end of the second air outlet channel 13 extends to the outside of the valve cover 90. Example

[0065] like Figure 8-11 As shown in Figures 19-34, a gas valve includes a valve body 10, a first valve core 20, and a second valve core 30. The valve body 10 is provided with an inlet channel 11, a first outlet channel 12, and a second outlet channel 13. A valve core cavity 14 is provided between the inlet channel 11, the first outlet channel 12, and the second outlet channel 13. The first valve core 20 and the second valve core 30 are rotatably disposed in the valve core cavity 14 and are connected to achieve synchronous rotation of the first valve core 20 and the second valve core 30. The first valve core 20 connects or blocks the inlet channel 11 and the first outlet channel 12, and the second valve core 30 connects or blocks the inlet channel 11 and the second outlet channel 13.

[0066] Specifically, the first valve core 20 has a first vent hole 21 axially located in the middle, and the second valve core 30 has a second vent hole 31 axially located in the middle. One end of the second vent hole 31 is connected to the first vent hole 21, and the other end is connected to the first vent channel 12. The first valve core 20 has a second vent hole 24, a third vent hole 25, and a fourth vent hole 26 radially arranged on one side. The diameter of the fourth vent hole 26 is larger than the diameter of the third vent hole 25, which is larger than the diameter of the second vent hole 24. That is, the fourth vent hole 26 is the large vent hole of the first vent channel 12 when it is under high heat, and the third vent hole 25 is the first vent channel. The second air inlet 24 is the small air inlet for the first air outlet channel 12 when the flame is low. One end of the second air inlet 24, the third air inlet 25 and the fourth air inlet 26 are respectively connected to the first air outlet 21, and the other end can be connected to the air inlet channel 11. The second valve core 30 is radially provided with a third air outlet 32 ​​on one side. One end of the third air outlet 32 ​​is connected to the second air outlet 31, and the other end can be connected to the second air outlet channel 13. The third air outlet 32 ​​can only be connected to the second air outlet channel 13 when the fourth air inlet 26 is connected to the air inlet channel 11.

[0067] When the first valve core 20 is rotated to 90 degrees to open the gas supply, one end of the second air inlet 24 first connects with the air inlet channel 11. At this time, the connection surface between the air inlet channel 11 and the second air inlet 24 is small, the gas flow into the first air inlet 22 is small, and the first gas outlet channel 12 is in a low flame state. The gas flows from the air inlet channel 11 through the second air inlet 24 into the first gas outlet 21, and then through the first gas outlet 21 and the second gas outlet 31 to the first gas outlet channel 12, and is output to the stove. Continue rotating the first valve core 20 to 130 degrees... When the first valve core 20 is rotated to 180 degrees, the third air inlet 25 connects with the air intake channel 11. At this time, the connection surface between the air intake channel 11 and the third air inlet 25 increases to 90 degrees, and the gas flow into the first air outlet 21 also increases accordingly. The first air outlet 12 is in a medium-fire state. When the first valve core 20 is rotated to 180 degrees, the fourth air inlet 26 connects with the air intake channel 11. At this time, the connection surface between the air intake channel 11 and the fourth air inlet 26 is large, and the gas flow into the first air outlet 21 is large. The first air outlet 12 is in a high-fire state. During the above process, although the second valve core 30 rotates synchronously with the first valve core 20, the third air outlet 32 ​​fails to rotate to connect with the second air outlet 13. Therefore, the second air outlet 13 remains in the off-fire state. When the first valve core 20 is rotated to 210 degrees, the fourth air inlet 26 continues to be connected to the air inlet channel 11, and at the same time, it drives the second valve core 30 to rotate to the third air outlet 32 ​​to connect with the second air outlet channel 13. After the gas flows into the second air outlet 31, it flows to the first air outlet channel 12 and also flows to the second air outlet channel 13 through the third air outlet 32. At this time, both the first air outlet channel 12 and the second air outlet channel 13 are in the high flame state, so that the stove reaches the intense flame state of dual high flame.

[0068] In this embodiment, preferably, the first valve core 20 is provided with a first retaining shaft 27 at one end near the second valve core 30 and a first retaining groove 28 at the other end. The second valve core 30 is provided with a second retaining groove 33 that matches the first retaining shaft 27 at one end near the first valve core 20. The first valve core 20 is fixedly connected to the second valve core 30 by inserting the first retaining shaft 27 into the second retaining groove 33.

[0069] In this embodiment, preferably, a connecting rod 40 is fixedly connected to the end of the first valve core 20 away from the second valve core 30. One end of the connecting rod 40 is provided with a second retaining shaft 41 that matches the first retaining groove 28, and the other end is provided with a third retaining groove 42. The connecting rod 40 is fixedly connected to the first valve core 20 by inserting the second retaining shaft 41 into the first retaining groove 28.

[0070] In this embodiment, preferably, it further includes an ignition assembly 50, which includes a base 51, a rotating shaft 52, an ignition paddle 53, a spring 54, and a pressure cap 55. The base 51 is fixed to the side of the valve body 10 near the connecting rod 40. The rotating shaft 52 is movably mounted on the base 51. One end of the rotating shaft 52 is provided with a locking plate 521 that matches the third locking slot 42. When igniting, the locking plate 521 of the rotating shaft 52 is inserted into the third locking slot 42 to achieve a movable connection with the connecting rod 40, and drives the connecting rod 40 to rotate synchronously with the rotating shaft 52. A child lock 56 is fixedly mounted on the locking plate 521. The other end of the rotating shaft 52 extends to the outside of the base 51. The ignition paddle 53 is fixedly mounted on the connecting rod 40. The spring 54 is sleeved on the connecting rod 40 and is located between the ignition paddle 53 and the child lock 56. The pressure cap 55 is fixedly mounted to the end of the rotating shaft 52 that extends to the outside of the base 51.

[0071] When igniting, press down on the pivot 52 to disengage the child lock 56 from the locking groove in the valve body 10, then rotate the pivot 52. As the pivot 52 rotates, it drives the connecting rod 40 to rotate synchronously, causing the ignition paddle 53 to rotate and ignite.
