Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, and in particular to a leak-proof gas valve. Background Technology

[0002] The gas valve is the core control component of a gas stove. It is usually equipped with an inlet channel and an outlet channel. The inlet channel introduces gas, and the outlet channel is connected to the gas stove. The valve core and valve stem of the gas valve control the flow of gas.

[0003] In the gas valves of the relevant technologies, the gas pipe used for gas intake is directly connected to the gas intake channel of the valve body. The gas is guided to the valve core of the gas valve through the gas guide chamber in the valve core, and the gas is guided to the gas outlet channel of the valve body through the gas guide chamber. The gas outlet channel can be directly connected to the gas stove. In this way, when the gas valve is opened, the valve stem of the valve body activates the solenoid valve of the valve body to realize the connection of the gas pipeline.

[0004] Because the gas pipe is directly connected to the valve core, when the gas valve is opened, the gas in the gas pipe will instantly enter the valve core. This will cause pressure fluctuations in the gas pressure guided to the gas stove through the valve core's conductive chamber, resulting in an unstable flame. Furthermore, the instantaneous pressure fluctuations entering the valve core can easily damage it, especially during the instant of opening and closing.

[0005] In addition, gas pipelines are opened and closed at the valve core, which places high demands on the valve core's sealing. Especially with long-term use, the seal is prone to failure, posing a risk of gas leakage. Utility Model Content

The valve stem passes through the valve body and can move up and down. A first elastic component is connected between the pushing mechanism and the valve body. The first elastic component is used to provide a first elastic stress to drive the pushing mechanism away from the blocking member. The pushing mechanism is used to be pressed by the valve stem when the valve stem moves downward, so as to move closer to the blocking member and drive the blocking member away from the first air outlet.

[0009] As an optional implementation, the pushing mechanism includes a connecting rod and a pushing rod. The pushing rod is rotatably connected to the valve body via the connecting rod. One end of the first elastic member is connected to the connecting rod, and the other end of the first elastic member abuts against the pushing rod to drive the pushing rod to rotate away from the blocking member. The push rod is used to be compressed when the valve stem moves downward and to rotate toward the blocking element.

[0010] As an optional implementation, the pushing mechanism further includes a pressure rod and a second elastic component. The pressure rod passes through the valve body and is movable up and down. The valve stem is used to press against the pushing rod after moving downward. The second elastic component is connected to the valve body and is used to provide a second elastic stress that drives the pressure rod to move upward.

[0011] As an optional implementation, the valve body is provided with a touch switch, which is used to be touched by the top pressure plate when the top pressure plate moves downward, and to send a first electrical signal to the electromagnetic push rod.

[0012] As an optional implementation, the solenoid valve further includes a thermal sensor switch for sending a second electrical signal to the solenoid actuator when the temperature rises.

[0017] In summary, this utility model has the following technical effects: In this application, when the gas valve is in operation, the gas in the gas pipe will be momentarily under high pressure. It is guided into the second conducting chamber of the solenoid valve through the gas inlet channel, rather than directly into the first conducting chamber of the valve body and then into the burner of the gas stove. In this way, the momentary fluctuation of the gas is first buffered by the second conducting chamber of the solenoid valve before being introduced into the valve core of the valve body, thus reducing the impact of the momentary introduction of gas on the valve core.

[0018] When not in operation, the residual gas can be blocked in the second conduction and intake passage by the solenoid valve's blocking component, which reduces the need for additional sealing structures in the valve core and the gas stove's outlet passage, thus providing better protection against gas leakage.

[0027] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0028] See Figures 1-9 This utility model discloses a leak-proof gas valve, including a valve body 10, a valve core 20, and a solenoid valve 30. The valve body 10 is provided with a guide channel 15, an inlet channel 11, and an outlet channel 13. The valve core 20 is rotatably mounted in a first conductive cavity 12. The valve core 20 is provided with a through hole 21, which communicates with the outlet channel 13 after the valve core 20 rotates. The valve core 20 can also be provided with a valve chamber 22, through which gas from the first conductive cavity 12 can be introduced and then discharged through the through hole 21 to the outlet channel 13. The solenoid valve 30 is mounted on the valve body 10 and is provided with a second conductive cavity 31.

[0029] Specifically, the intake channel 11 is connected to the second guiding cavity 31, one end of the guide channel 15 is connected to the second guiding cavity 31, and the other end of the guide channel 15 is connected to the first guiding cavity 12. The solenoid valve 30 can block or open the second guiding cavity 31 and the guide channel 15.

[0030] Based on the above structure, when using the leak-proof gas valve of this utility model, the gas pipeline can be connected to the air inlet channel 11 of the valve body 10. The air inlet channel 11 is connected to the second conduction cavity 31 of the solenoid valve 30, and the second conduction cavity 31 can be connected to the guide channel 15. The guide channel 15 is connected to the first conduction cavity 12 of the valve body 10.

[0031] When in operation, the solenoid valve 30 can be opened. After the solenoid valve 30 is opened, the air intake channel 11 and the second conduction chamber 31 of the solenoid valve 30 are in a conducting state. The valve core 20 rotates to the state where its conduction hole 21 is in a conducting state with the air outlet channel 13. The gas enters the second conduction chamber 31 of the solenoid valve 30 through the air intake channel 11. The gas in the second conduction chamber 31 enters the guide channel 15 and enters the first conduction chamber 12 through the guide channel 15. The valve chamber 22 of the valve core 20 guides the gas to the conduction hole 21, and then guides it to the air outlet channel 13. Finally, the gas is guided to the gas stove for use through the air outlet channel 13.

[0032] When the solenoid valve 30 is opened, the gas in the gas pipe will be instantly under high pressure. It is guided into the second conduction chamber 31 of the solenoid valve 30 through the gas inlet channel 11, instead of directly entering the first conduction chamber 12 of the valve body 10 and then entering the burner of the gas stove. In this way, the instantaneous fluctuation of the gas is first buffered by the second conduction chamber 31 of the solenoid valve 30 before being introduced into the valve core 20 of the valve body 10. Therefore, the impact of the instantaneous introduction of gas on the valve core 20 can be reduced.

[0033] When not in operation, i.e., when no gas is used, the solenoid valve 30 is closed. The gas inlet channel 11, which is connected to the gas pipe, is connected to the second conduction chamber 31 of the solenoid valve 30. Therefore, after the solenoid valve 30 is closed, its own sealing structure prevents gas leakage at the position of the gas inlet channel 11 and the second conduction chamber 31. At the valve core 20, since the solenoid valve 30 blocks the second conduction chamber 31 and the guide channel 15, no gas enters the first conduction chamber 12 of the valve body 10 after the solenoid valve 30 is closed. Therefore, the residual gas at the first conduction chamber 12 connected to the gas stove and the gas outlet channel 13 is consumed, and there is no gas. Therefore, there is no gas at the valve core 20 position and the position connected to the gas stove, so the risk of gas leakage is low.

[0034] As an optional implementation, the second conductive cavity 31 has a first air inlet 311 and a first air outlet. The first air inlet 311 is connected to the air inlet channel 11, and the first air outlet is connected to the guide channel 15. The solenoid valve 30 is provided with a blocking element 33 and an electromagnetic push rod. The blocking element 33 can move closer to or away from the first air outlet to block or open the first air outlet. The electromagnetic push rod is used to drive the blocking element 33 away from the first air outlet after being energized.

[0035] In addition, the valve body 10 is also provided with a valve stem 50 and a pushing mechanism. The valve stem 50 passes through the valve body 10 and can move up and down. A first elastic member 45 is connected between the pushing mechanism and the valve body 10. The first elastic member 45 can provide a first elastic stress, which can act on the pushing mechanism to drive it away from the blocking member 33. The pushing mechanism is pressed by the valve stem 50 when the valve stem 50 moves downward, so as to move closer to the blocking member 33 and drive the blocking member 33 away from the first air outlet.

[0036] Based on this structure, when the solenoid valve 30 is opened, the user can press the valve stem 50 to drive it downward. After the valve stem 50 moves downward, it can press the push mechanism. When the push mechanism receives the pressing action of the valve stem 50, it can approach the blocking member 33 and drive the blocking member 33 away from the first gas outlet. This opens the first gas outlet, which is in a conductive state, so that the second conductive cavity 31 is connected to the guide channel 15. The gas can then enter the first air inlet 311 through the air inlet channel 11, be guided to the second conductive cavity 31 through the first air inlet 311, and then enter the guide channel 15 through the first gas outlet. The guide channel 15 guides the gas to the first conductive cavity 12 and into the valve cavity 22 of the valve core 20. The gas is then guided to the gas outlet 13 through the guide hole 21, thus realizing the gas conduction.

[0037] When not in operation, the valve stem 50 moves upward, and the first elastic component 45 resets, driving the push mechanism away from the blocking component 33. The solenoid valve 30 is energized, and the electromagnetic push rod drives the blocking component 33 to move closer to the first gas outlet. The blocking component 33 can then block the first gas outlet, keeping the second conduction cavity 31 and the guide channel 15 in a blocked state. In this way, the residual gas volume can be blocked in the second conduction and intake channel 11 and sealed by the blocking component 33 of the solenoid valve 30. This reduces the need for additional sealing structures at the valve core 20 and the gas outlet channel 13 of the gas stove, thus improving the gas leakage prevention effect.

[0038] Of course, it should be noted that when the electromagnetic push rod is energized, the user can first press the push mechanism with the valve rod 50. After the push mechanism presses the blocking part 33, the blocking part 33 is pressed away from the first gas outlet, thus opening the gas pipeline. After that, the electromagnetic push rod can receive an electrical signal after the blocking part 33 is pressed, so that the electromagnetic push rod is energized and drives the blocking part 33 away from the first gas outlet, so that the gas pipeline remains open during use.

[0039] Each time the gas valve is opened, the user must manually press the valve stem 50 to activate the push mechanism before it can be opened. This makes the process safer and prevents the gas valve from being opened accidentally.

[0040] More specifically, the aforementioned pushing mechanism includes a connecting rod and a pushing rod 41. The pushing rod 41 is rotatably connected to the valve body 10 via the connecting rod. One end of the first elastic member 45 is connected to the connecting rod, and the other end of the first elastic member 45 abuts against the pushing rod 41 to drive the pushing rod 41 to rotate away from the blocking member 33. The aforementioned pushing rod 41 can be compressed when the valve stem 50 moves downward and rotate towards the blocking member 33.

[0041] When the gas is turned on, the user presses down on the valve stem 50. The downward movement of the valve stem 50 drives the push rod 41 downward, compressing the first elastic component 45. The push rod 41 then rotates downward and toward the blocking component 33, pushing it away from the first gas outlet. Afterward, the first elastic component 45 causes the push rod 41 to return to its original position, allowing it to rotate upward away from the blocking component 33. This causes the electromagnetic push rod to move the blocking component 33 toward the first gas outlet, thus sealing the gas pipeline.

[0042] As an optional implementation, the aforementioned pushing mechanism further includes a pressure rod 42 and a second elastic member 43. The pressure rod 42 passes through the valve body 10 and can move up and down. The valve stem 50 is used to press against the pushing rod 41 after moving downward. The second elastic member 43 is connected to the valve body 10, and the second elastic member 43 can provide a second elastic stress to drive the pressure rod 42 to move upward. The valve stem 50 is connected to a pressure plate 52, which can press against the pressure rod 42 when the valve stem 50 moves downward, thereby driving the pressure rod 42 to move downward.

[0043] When opening the gas valve, the user presses the valve stem 50, causing the pressure plate 52 of the valve stem 50 to move relative to it, pressing down on the pressure rod 42. The pressure rod 42 then presses down on the push rod 41. The downward movement of the valve stem 50 is applied to the pressure rod 42 by the pressure plate 52, resulting in a larger pressure surface. This eliminates the need for precise positioning, reducing the difficulty of opening the solenoid valve 30. Furthermore, since the push plate presses down on the pressure rod 42, which in turn presses down on the push rod 41, the valve stem 50 only needs a smaller downward movement, compensated for by the length of the pressure rod 42 itself. Therefore, the force applied to the valve stem 50 is less needed to start the gas valve, making it easier to activate.

[0044] Specifically, a touch switch 36 can also be provided on the valve body 10. The touch switch 36 can be touched by the top pressure plate 52 when the top pressure plate 52 moves downward and send a first electrical signal to the electromagnetic push rod.

[0045] When starting the gas valve, the user can press the valve stem 50, causing it to move downwards. After the valve stem 50 moves downwards, the pressure plate 52 connected to the valve stem 50 can press the pressure rod 42 of the push mechanism, which in turn presses the push rod 41. The push rod 41 rotates downwards, causing the blocking member 33 to move away from the first gas outlet. At the same time, the pressure plate 52 can also trigger the touch switch 36 when moving downwards. After being pressed, the touch switch 36 can send a first electrical signal. The electromagnetic push rod can be activated according to the first electrical signal, causing it to move the blocking member 33 away from the first gas outlet. Under the action of the electromagnetic push rod, the blocking member 33 remains open at the first gas outlet, thus ensuring continuous gas pipeline operation and stable gas usage.

[0046] Each start-up action is initiated by the top pressure plate 52 triggering the touch switch 36, which means that a mechanical action is first required to start the gas valve, and then an electrical signal is used to keep the gas valve in a conductive state, making the process safer.

[0047] Furthermore, the aforementioned solenoid valve 30 also includes a thermal sensing switch 35, which is used to send a second electrical signal to the solenoid actuator when the temperature rises.

[0048] When the gas valve is activated, the top pressure plate 52 triggers the touch switch 36, which then energizes the electromagnetic push rod to keep the blocking member 33 in the open state. After the gas stove ignites, the heat generated by combustion is transferred to the thermal sensor switch 35. After being heated, the thermal sensor switch 35 can transmit a second electrical signal, which is then transmitted to the electromagnetic push rod. The electromagnetic push rod can remain energized, driving the blocking member 33 to remain in a conducting state away from the first gas outlet.

[0049] Since the pressure rod 42 can be reset under the action of the second elastic component 43, after the pressure rod 42 moves upward under the action of the second elastic component 43, it will act upward on the top pressure plate 52. In this way, the top pressure plate 52 will also be reset upward. Thus, the top pressure plate 52 will move away from the touch switch 36. After the touch switch 36 is turned off, since the gas stove maintains an upward temperature after ignition, the thermal sensor switch 35 can continuously send a second electrical signal when the gas stove is in operation. The energized state of the electromagnetic push rod can be maintained by the second electrical signal. In this way, even if the push rod 41, the pressure rod 42 and the valve stem 50 are reset, the opening state of the electromagnetic push rod driving the blocking component 33 away from the first gas outlet can be maintained by the thermal sensor switch 35 in the ignition state, and the gas conduction state is stable.

[0050] Each time gas is supplied, the valve stem 50 pushes the pressure rod 42 downwards, causing the pressure rod 42 to press against the push rod 41. The push rod 41 then mechanically presses against the blocking member 33, driving the blocking member 33 away from the first gas outlet. Simultaneously, the touch switch 36, which acts as a mechanical switch, is triggered, activating the electromagnetic push rod. At this point, the electromagnetic push rod moves the blocking member 33 away from the first gas outlet, allowing gas supply and initiating the initial ignition. After ignition, the temperature rises, triggering the thermal sensor switch 35. This allows the electromagnetic push rod, under the influence of a second electrical signal, to continuously act on the blocking member 33, keeping the first gas outlet open.

[0051] As an optional implementation, to facilitate the pressing operation with the adjusting sleeve 60, an adjusting sleeve 60 can also be connected to the top of the valve stem 50. The adjusting sleeve 60 is provided with a first connecting part, and the valve core 20 is provided with a second connecting part. The second connecting part is slidably connected to the first connecting part. The adjusting sleeve 60 extends out of the valve body 10 and forms an adjusting section. In this way, the user can act on the adjusting sleeve 60 to drive the adjusting sleeve 60 to move downward, thereby driving the valve stem 50 to move downward, realizing the pressing action on the pressure rod 42, which is convenient to operate.

[0052] Because the first connecting part on the adjusting sleeve 60 and the second connecting part of the valve core 20 are provided for sliding cooperation, the up and down movement of the adjusting sleeve 60 can be guided by the sliding cooperation of the first connecting part and the second connecting part. The adjusting sleeve 60 is not prone to swaying when it is pressed down, so the pressing position is more accurate.

[0053] Since the valve core 20 is provided with a through hole 21, the valve core 20 can be rotated by operating the adjusting sleeve 60. In this way, the through hole 21 of the valve core 20 can be connected with the gas outlet channel 13 to realize the connection of the gas pipeline.

[0054] Specifically, multiple through holes 21 of different diameters can be set in the valve core 20. When adjusting the gas volume, the adjusting sleeve 60 is rotated. The second connecting part of the adjusting sleeve 60 and the first connecting part of the valve core 20 only have a sliding tendency to slide up and down. Therefore, when the adjusting sleeve 60 rotates, the relative rotation between the adjusting sleeve 60 and the valve core 20 is restricted by the second connecting part and the first connecting part. The adjusting sleeve 60 can then drive the valve core 20 to rotate together, so that the different adjusting holes of the valve core 20 correspond to the gas outlet channel 13, thereby realizing the adjustment of the gas volume and the firepower of the gas stove can be adjusted.

[0055] As an optional implementation, the adjusting sleeve 60 is provided with a snap-fit ​​block; the valve core 20 is provided with a snap-fit ​​interface, and the snap-fit ​​block and the snap-fit ​​interface are slidably snapped together.

[0056] Thus, the sliding assembly of the adjusting sleeve 60 and the valve core 20 can be achieved through the assembly of the snap-fit ​​block and the snap-fit ​​interface. The snap-fit ​​block and the snap-fit ​​interface only have the tendency to slide up and down, and the rotational movement is restricted. Therefore, when the adjusting sleeve 60 is under pressure, it can drive the valve stem 50 up and down, and when the adjusting sleeve 60 is rotated by external force, it can also drive the valve core 20 to rotate.

[0057] Based on this structure, the first connecting part includes a snap-fit ​​interface, while the second connecting part includes a snap-fit ​​block. In other embodiments, the first connecting part may also include a slotted hole, and the corresponding second connecting part may include a sliding rod, which guides the up-and-down movement of the adjusting sleeve 60 and the valve core 20 by sliding the sliding rod through the slotted hole.

[0058] As an optional implementation, a third elastic component 51 is provided between the top end of the valve core 20 and the bottom end of the adjusting sleeve 60. The third elastic component 51 provides a third elastic stress to drive the adjusting sleeve 60 upward. Similarly, after the adjusting sleeve 60 is pressed downward, the third elastic component 51 can be compressed. Thus, when the adjusting sleeve 60 resets, the third elastic component 51 can provide a third elastic stress to drive the adjusting sleeve 60 downward to achieve reset. In addition, the push rod 41 is reset by the first elastic stress provided by the first elastic component 45, while the pressure rod 42 is reset by the second elastic stress provided by the second elastic component 43. Under the action of the top pressure plate 52, both the first elastic stress and the second elastic stress can provide a reset force, making the reset action rapid.

[0059] As an optional implementation, the solenoid valve 30 further includes a conductive housing 34, in which a second conductive cavity 31 and a guide cavity 341 are provided. A first air inlet 311 is provided on the side of the conductive housing 34, and a first air outlet communicates with the guide cavity 341. A guide channel 15 is provided on the side of the guide cavity 341. The solenoid valve 30 is installed on the conductive housing 34, and the electromagnetic push rod and the blocking member 33 are both provided in the guide cavity 341. A second air outlet 14 and a second air inlet 16 are provided on the side of the valve body 10. When assembling the solenoid valve 30 with the valve body 10, the conductive housing 34 of the solenoid valve 30 is sealed and covered on the side of the valve body 10. After the cover is closed, a sealing ring or sealant can be clamped between the side of the conductive housing 34 and the side of the valve body 10. In this way, the solenoid valve 30 and the valve body 10 are sealed and assembled, so that the first air inlet 311 is connected to the second air outlet 14, and the second air inlet 16 is connected to the guide cavity 341.
