Description

Technical Field

[0001] The present invention relates to the technical field of gas valves, and in particular to a leakage-proof gas valve. Background Art

[0002] The gas valve is the core control component of the gas stove. Usually, an air inlet channel and an air outlet channel are set on the gas valve. The air inlet channel is used to introduce gas, and the air outlet channel is connected to the gas stove. The valve core and valve stem of the gas valve realize the on and off of gas.

[0003] In the gas valve in the related art, the gas pipe used for air intake is directly connected to the air intake channel of the valve body, the air intake channel guides the gas to the valve core of the gas valve, and the air guide cavity in the valve core guides the gas to the air outlet channel of the valve body. The air 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 starts the solenoid valve of the valve body to realize the conduction of the gas pipeline.

[0004] Because the gas pipeline is directly connected to the valve core, when the gas valve is opened, the gas in the gas pipeline will instantly enter the valve core. This will cause the gas pressure in the valve core's conduction cavity to the gas stove to fluctuate, resulting in an unstable flame. The instantaneous gas pressure fluctuations entering the valve core can also easily damage the valve core, especially during the on-off moment.

[0005] In addition, the gas pipeline is connected and disconnected at the valve core position, so the sealing requirements of the valve core are relatively high. Especially in long-term use, the seal is prone to failure, and there is a risk of gas leakage. Summary of the Invention

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

[0027] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

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

[0029] Specifically, the intake channel 11 is connected to the second conduction chamber 31, connecting one end of the guide channel 15 to the second conduction chamber 31, and the other end of the guide channel 15 to the first conduction chamber 12, and the solenoid valve 30 can block or connect the second conduction chamber 31 and the guide channel 15.

[0030] Based on the above structure, when using the leak-proof gas valve of the present invention, the gas pipeline can be connected to the air intake channel 11 of the valve body 10, and the air intake 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, and the guide channel 15 is connected to the first conduction cavity 12 of the valve body 10.

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

[0032] When the solenoid valve 30 is opened, the gas in the gas pipe will enter at an instantaneous high pressure. This gas is guided by the air inlet passage 11 into the second conduction chamber 31 of the solenoid valve 30 rather than directly into the first conduction chamber 12 of the valve body 10 and then into 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, thereby reducing the impact of the instantaneous introduction of the gas on the valve core 20.

[0033] In the non-operating state, meaning that gas is not being used, the solenoid valve 30 is closed, and the air inlet passage 11 connected to the gas pipe is in communication with the second conduction chamber 31 of the solenoid valve 30. Therefore, after the solenoid valve 30 is closed, the sealing structure of the solenoid valve 30 prevents gas leakage between the air inlet passage 11 and the second conduction chamber 31. At the valve core 20, since the solenoid valve 30 blocks the second conduction chamber 31 from the guide passage 15, no gas enters the first conduction chamber 12 of the valve body 10 when the solenoid valve 30 is closed. Consequently, the residual gas in the first conduction chamber 12 and the air outlet passage 13 connected to the gas stove is consumed, and no gas is present. Therefore, no gas is present at the valve core 20 or at the location connected to the gas stove, thus minimizing the risk of gas leakage.

[0034] As an optional implementation, specifically, the second conducting cavity 31 has a first gas inlet 311 and a first gas outlet, the first gas inlet 311 is communicated with the gas inlet channel 11, and the first gas outlet is communicated with the guide channel 15. The electromagnetic valve 30 is provided with a blocking member 33 and an electromagnetic push rod, the blocking member 33 is movable towards or away from the first gas outlet to block or open the first gas outlet, and the electromagnetic push rod is used to drive the blocking member 33 to move away from the first gas outlet after being powered.

[0035] In addition, the valve body 10 is further provided with a valve rod 50 and a pushing mechanism, the valve rod 50 is connected to the valve body 10 and is movable 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, the first elastic stress can act on the pushing mechanism to drive the pushing mechanism to move away from the blocking member 33. The pushing mechanism is used to be pressed by the valve rod 50 when the valve rod 50 moves downward, so as to move close to the blocking member 33 and drive the blocking member 33 to move away from the first gas outlet.

[0036] On the basis of the structure, when the electromagnetic valve 30 is opened, the user can press the valve rod 50 to drive the valve rod 50 to move downward, after the valve rod 50 moves downward, the valve rod 50 can press the pushing mechanism, and the pushing mechanism can move close to the blocking member 33 and drive the blocking member 33 to move away from the first gas outlet when receiving the pressing action of the valve rod 50. In this way, the first gas outlet is opened, the first gas outlet is in a conducting state, the second conducting cavity 31 is communicated with the guide channel 15, and the gas can enter the first gas inlet 311 through the gas inlet channel 11, be guided to the second conducting cavity 31 through the first gas inlet 311, enter the guide channel 15 through the first gas outlet, be guided to the first conducting cavity 12 through the guide channel 15, enter the valve cavity 22 of the valve core 20, be guided to the gas outlet channel 13 through the conducting hole 21, and realize gas conduction.

[0037] When in a non-working state, the valve rod 50 moves upward, the first elastic member 45 resets to drive the pushing mechanism to move away from the blocking member 33, the electromagnetic valve 30 is powered, the electromagnetic push rod drives the blocking member 33 to move close to the first gas outlet, the blocking member 33 can block the first gas outlet, the second conducting cavity 31 and the guide channel 15 are in a blocking state, and the residual amount of gas can be blocked in the second conducting cavity and the gas inlet channel 11 by the blocking member 33 of the electromagnetic valve 30. In this way, the sealing structure needs to be additionally arranged at the valve core 20 and the gas outlet channel 13 of the gas stove, so that the anti-gas leakage effect is better.

[0038] Of course, it should be noted that when the electromagnetic push rod is energized, the user can first use the valve stem 50 to press the pushing mechanism. After the pushing mechanism presses the blocking member 33, the blocking member 33 is pressed and moves away from the first air outlet, thereby realizing the gas pipeline. After that, the electromagnetic push rod can receive an electrical signal after the blocking member 33 is pressurized, so that the electromagnetic push rod is energized to drive the blocking member 33 away from the first air outlet, so that the gas remains in an open state during use.

[0039] Each time the gas valve is opened, the user needs to manually press the valve stem 50 to perform the pushing action of the pushing mechanism before the valve can be opened. This makes the use process safer and prevents the gas valve from being opened due to accidental touch.

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

[0041] When the gas is turned on, the user presses the valve stem 50, causing it to move downward, which in turn drives the push rod 41 downward. At this point, the first elastic member 45 is compressed, causing the push rod 41 to rotate downward and toward the blocking member 33. The push rod 41 pushes the blocking member 33, forcing it away from the first gas outlet and opening. Thereafter, the first elastic member 45 drives the push rod 41 back to its original position, causing it to rotate upward, away from the blocking member 33. The electromagnetic push rod then drives the blocking member 33 toward the first gas outlet, sealing the gas line.

[0042] As an optional embodiment, the above-mentioned pushing mechanism further includes a pressure rod 42 and a second elastic component 43. The pressure rod 42 is connected to the valve body 10 and can move up and down. The valve stem 50 is used to press the pushing rod 41 after moving downward. The second elastic component 43 is connected to the valve body 10, and the second elastic component 43 can provide a second elastic stress that drives the pressure rod 42 to move upward. The valve stem 50 is connected to a pressing plate 52. The pressing plate 52 can press 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 pressing plate 52 of the valve stem 50 to move relative to it, pressing downward on the pressure-receiving rod 42, which in turn presses the push rod 41 downward. This allows the downward movement of the valve stem 50 to be applied to the pressure-receiving rod 42 via the pressing plate 52. This creates a larger pressing surface, eliminating the need for precise positioning to achieve the pushing action, and reducing the difficulty of opening the solenoid valve 30. Furthermore, because the push plate presses against the pressure-receiving rod 42, which in turn presses against the push rod 41, the valve stem 50 only needs to move downward for a shorter distance, with the length of the pressure-receiving rod 42 compensating for the distance. Consequently, the gas valve can be activated even with a relatively small force applied to the valve stem 50, making gas valve activation easier.

[0044] Specifically, a touch switch 36 may be further provided on the valve body 10 . The touch switch 36 may 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 activating the gas valve, the user can press the valve stem 50, driving it downward. After the valve stem 50 moves downward, the pressure plate 52 connected to the valve stem 50 can press the pressure rod 42 of the push mechanism, and the pressure rod 42 presses the push rod 41, causing the push rod 41 to rotate downward, driving the blocking member 33 away from the first gas outlet. At the same time, the pressure plate 52 can also trigger the touch switch 36 during its downward movement. When pressed, the touch switch 36 can send a first electrical signal, which can activate the electromagnetic push rod based on the first electrical signal, driving the electromagnetic push rod 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 in the open state of the first gas outlet, so that the gas pipeline remains conductive and the gas usage is stable.

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

[0047] Furthermore, the solenoid valve 30 further includes a thermal sensing switch 35 , which is configured to send a second electrical signal to the electromagnetic push rod when the temperature rises.

[0048] When the gas valve is started, the top pressure plate 52 triggers the touch switch 36, and then the electromagnetic push rod is energized to keep the blocking member 33 in the open state. In this way, after the gas stove is ignited, the heat generated by the combustion will be transferred to the thermal sensing switch 35. After being heated, the thermal sensing switch 35 can transmit a second electrical signal, which is transmitted to the electromagnetic push rod with the second electrical signal. The electromagnetic push rod can remain energized, driving the blocking member 33 to remain in a conductive 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, the pressure rod 42 will act on the top pressure plate 52 upward after moving upward under the action of the second elastic component 43, so that the top pressure plate 52 will also reset upward, so that the top pressure plate 52 will be away from the touch switch 36. After the touch switch 36 is disconnected, since the temperature of the gas stove remains in an rising state after ignition, the thermal sensing switch 35 can continue to send a second electrical signal when the gas stove is in the working state, and the power-on 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 electromagnetic push rod drives the blocking member 33 away from the open state of the first air outlet, which can be maintained by the thermal sensing switch 35 in the ignition state, and the gas conduction state is stable.

[0050] Each time the gas is turned on, the valve stem 50 pushes the pressure-receiving rod 42 downward, allowing the pressure-receiving rod 42 to press the push rod 41. The push rod 41 mechanically presses the blocking member 33, forcing 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. This then drives the blocking member 33 away from the first gas outlet, turning the gas on and initiating the initial ignition. After ignition, the temperature rises and the thermal sensor switch 35 is triggered. This allows the electromagnetic push rod to continue acting on the blocking member 33 under the influence of the second electrical signal, keeping the first gas outlet open.

[0051] As an optional embodiment, in order to facilitate the top-pressing operation with the adjusting sleeve 60, an adjusting sleeve 60 can also be connected to the top end of the valve stem 50, and the adjusting sleeve 60 is provided with a first connecting portion, and the valve core 20 is provided with a second connecting portion, and the second connecting portion is slidably connected to the first connecting portion; the adjusting sleeve 60 extends out of the valve body 10 and is formed into an adjusting section, so that the user can act on the adjusting sleeve 60 to drive the adjusting sleeve 60 to move downward, drive the valve stem 50 to move downward, and realize the top-pressing action on the pressure rod 42, which is easy to operate.

[0052] Since the adjusting sleeve 60 is provided with a first connecting portion that slides up and down with the second connecting portion of the valve core 20, the up and down movement of the adjusting sleeve 60 can be guided by the sliding cooperation of the first connecting portion and the second connecting portion. The adjusting sleeve 60 is not prone to deflection when pressed downward, so that the top pressure position is more accurate.

[0053] Since the valve core 20 is provided with a conducting hole 21, the valve core 20 can be rotated by operating the adjustment sleeve 60, so that the conducting hole 21 of the valve core 20 can be connected to the gas outlet channel 13 to achieve the conduction of the gas pipeline.

[0054] Specifically, a plurality of conducting holes 21 with different apertures can be provided in the valve core 20. When the gas volume is adjusted, the adjusting sleeve 60 is rotated, and the second connecting portion of the adjusting sleeve 60 and the first connecting portion 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 of the adjusting sleeve 60 and the valve core 20 is restricted by the second connecting portion and the first connecting portion. The adjusting sleeve 60 can drive the valve core 20 to rotate together, so that different adjusting holes of the valve core 20 correspond to the gas outlet channel 13, thereby realizing the adjustment of the gas volume and adjusting the firepower of the gas stove.

[0055] As an optional embodiment, the regulating sleeve 60 is provided with a clamping block; the valve core 20 is provided with a clamping interface, and the clamping block is slidably clamped with the clamping interface.

[0056] In this way, the sliding assembly of the adjusting sleeve 60 and the valve core 20 can be achieved by assembling the clamping block and the clamping interface, and the clamping block and the clamping interface only have a tendency to slide up and down, and the rotational movement is restricted. Therefore, the adjusting sleeve 60 can drive the valve stem 50 up and down when under pressure, and the adjusting sleeve 60 can also drive the valve core 20 to rotate when rotated by external force.

[0057] Based on this structure, the first connecting portion includes a snap-in interface, while the second connecting portion includes a snap-in block. In other implementations, the first connecting portion may also include a strip-shaped hole, and the corresponding second connecting portion may include a sliding rod, with the sliding rod and the strip-shaped hole sliding to guide the vertical movement of the adjustment sleeve 60 and the valve core 20.

[0058] As an optional embodiment, a third elastic component 51 is disposed between the top end of the valve core 20 and the bottom end of the adjustment sleeve 60. The third elastic component 51 is used to provide a third elastic stress that drives the adjustment sleeve 60 upward. Similarly, after the adjustment sleeve 60 is pressed downward, the third elastic component 51 can be compressed. Thus, when the adjustment sleeve 60 is reset, the third elastic component 51 can provide a third elastic stress to drive the adjustment 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 and second elastic stresses can provide reset force, making the reset action rapid.

[0059] As an optional embodiment, the solenoid valve 30 also includes a conducting shell 34, in which a second conducting chamber 31 and a guide chamber 341 are provided, the first air inlet 311 is provided on the side of the conducting shell 34, and the first air outlet is connected to the guide chamber 341; a guide channel 15 is provided on the side of the guide chamber 341; the solenoid valve 30 is installed in the conducting shell 34, and the electromagnetic push rod and the blocking member 33 are both provided in the guide chamber 341; the side of the valve body 10 is provided with a second air outlet 14 and a second air inlet 16. When the solenoid valve 30 is assembled with the valve body 10, the conducting shell 34 of the solenoid valve 30 is sealed and covered on the side of the valve body 10. After covering, a sealing ring or sealant or other sealing structure can be clamped between the side of the conducting shell 34 and the side of the valve body 10.
