Description

Technical Field

[0001] The utility model relates to the technical field of gas devices, in particular to a water-gas linkage valve and a gas device. Background Art

[0002] Gas devices such as gas water heaters or wall-mounted boilers use gas as fuel to provide domestic hot water or heating hot water for users. Usually, a water-gas linkage valve is relied on to control the opening of the gas valve and the gas pressure, so as to provide water with different heat loads for users.

[0003] The water-gas linkage valve includes a gas valve. In order to prevent the gas device from exploding during ignition, in the prior art, in addition to the main gas passage on the gas valve body, a dedicated ignition passage is also provided. The gas in the intake passage is shunted into the gas passage and the dedicated ignition passage through a shunt passage. A combustion solenoid valve is used to control the connection between the intake passage and the main gas passage, and an ignition solenoid valve is used to control the connection between the shunt passage and the dedicated ignition passage. The structure is relatively complex, and the processing and material costs are high. Summary of the Utility Model

[0004] One of the technical problems solved by the utility model is to provide a water-gas linkage valve, which can effectively solve the problem that the existing water-gas linkage valve will explode during ignition; moreover, the structure is simple, and the production cost is reduced.

[0006] The above first technical problem is solved by the following technical solutions:

[0007] A water-gas linkage valve includes a gas valve. The gas valve includes a gas valve body and a solenoid valve. An intake passage, an outlet passage and a valve cavity are arranged in the gas valve body.

[0010] The gas-water linkage valve provided by the present utility model has an opening area of the second valve port smaller than that of the first valve port. During ignition, the second valve port with a smaller opening area is opened through the ignition solenoid valve, and the gas in the intake passage enters the outlet passage through the second valve port. A smaller flow rate of gas enters the combustion chamber to achieve ignition, effectively avoiding deflagration caused by excessive gas flow rate during ignition. After successful ignition, the first valve port with a larger opening area is opened through the combustion solenoid valve, and the gas in the intake passage enters the outlet passage through the first valve port, so that a larger flow rate of gas enters the combustion chamber for combustion, and the ignition solenoid valve is closed to block the second valve port. Among them, by sharing the outlet passage, there is no need to separately set a dedicated ignition passage, the structure is relatively simple, and the production cost is reduced.

Among the first valve cavity and the second valve cavity, the axis of one of them is perpendicular to both the axis of the intake passage and the axis of the outlet passage, and the axis of the other is on the same straight line as the axis of one of the intake passage and the outlet passage.

[0012] In one embodiment, the axis of the first valve cavity or the second valve cavity is on the same straight line as the axis of the outlet passage.

[0013] In one embodiment, the second valve cavity and the first valve cavity are respectively located on adjacent sides of the intake passage.

[0014] In one embodiment, the axis of the first valve cavity and the axis of the second valve cavity are perpendicular to each other and are in the same plane.

[0015] In one embodiment, the gas valve body extends inwards to form a connecting portion, and the first valve port, the second valve port and the outlet passage are arranged on the connecting portion.

[0016] In one embodiment, a peripheral edge surrounding the first valve port protrudes from the side wall of the connecting portion towards the direction of the first valve cavity, and the combustion solenoid valve can abut against the peripheral edge to block the first valve port.

[0017] In one embodiment, a convex edge surrounding the second valve port protrudes from the side wall of the connecting portion towards the direction of the second valve cavity, and the ignition solenoid valve can abut against the convex edge to block the second valve port.

[0018] In one embodiment, both the combustion solenoid valve and the ignition solenoid valve are double-coil solenoid valves.

[0019] The above second technical problem is solved by the following technical solution:

[0021] Compared with the background art, the beneficial effects of the gas device described in the present utility model are as follows:

[0022] The gas device provided by the present utility model, by applying the above water-gas linkage valve, can ensure that the gas device will not explode and burn during startup, and simplifies the structure of the gas valve body, making the structure of the gas valve more compact and reducing the production cost.

[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0039] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0041] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements.

[0042] Such as Figure 1As shown in the figure, this embodiment provides a gas-water linkage valve, which includes a gas valve 100, a water valve 200, and a linkage valve 300. The water valve 200 is connected to the gas valve 100 through the linkage valve 300. Water enters the gas-water linkage valve from the water valve 200, and the linkage valve 300 controls the linkage of the gas valve 100, so that gas enters the gas-water linkage valve from the gas valve 100, passes through the gas valve 100 and enters the combustion chamber for ignition and combustion to provide heat for the water, thereby realizing the provision of hot water for users.

[0043] As Figure 2 shown, the gas valve 100 includes a gas valve body 1, a solenoid valve, a pressure stabilizing valve 4, and a gas valve core 5. An air inlet passage 11, an air outlet passage 12, a valve cavity 13, and a mounting cavity are provided in the gas valve body 1. The solenoid valve is arranged in the valve cavity 13 to control the connection of the air inlet passage 11 and the air outlet passage 12. A pressure stabilizing valve 4 is connected to one end of the air outlet passage 12 far from the valve cavity 13, and the gas valve core 5 is arranged in the mounting cavity. Gas enters the valve cavity 13 from the air inlet passage 11. After the solenoid valve is opened, the gas passes through the valve cavity 13 and enters the air outlet passage 12, and then the pressure of the air outlet passage 12 is regulated by the pressure stabilizing valve 4, and then the flow rate is regulated by the gas valve core 5 and enters the combustion chamber.

[0044] Specifically, as Figure 2 and Figure 3 shown, the solenoid valve includes an ignition solenoid valve 2 and a combustion solenoid valve 3. The valve cavity 13 includes a first valve cavity 131 and a second valve cavity 132 that communicate with each other. The air outlet passage 12 is provided with a first valve port 14 corresponding to the first valve cavity 131 and a second valve port 15 corresponding to the second valve cavity 132. The combustion solenoid valve 3 is arranged in the first valve cavity 131 to control the opening and closing of the first valve port 14; the ignition solenoid valve 2 is arranged in the second valve cavity 132 to control the opening and closing of the second valve port 15; the opening area of the first valve port 14 is larger than the opening area of the second valve port 15. During ignition, the second valve port 15 with a smaller opening area is opened through the ignition solenoid valve 2, and the gas in the air inlet passage 11 enters the air outlet passage 12 through the second valve port 15. A smaller flow rate of gas enters the combustion chamber to achieve ignition, which can effectively avoid deflagration due to excessive gas flow during ignition. After successful ignition, the first valve port 14 with a larger opening area is opened through the combustion solenoid valve 3, and the gas in the air inlet passage 11 enters the air outlet passage 12 through the first valve port 14, so that a larger flow rate of gas enters the combustion chamber for combustion. After waiting for a certain time, the ignition solenoid valve 2 is closed to block the second valve port 15. Among them, by sharing the air outlet passage 12, there is no need to separately set a dedicated ignition passage, and the structure is relatively simple, reducing the production cost.

[0045] It should be noted that the opening area of the second valve port 15 can be designed according to the gas flow rate required during ignition.

[0046] Specifically, the ignition solenoid valve 2 includes an ignition fixed shaft 21, an ignition moving shaft 22, an ignition sealing cap 23, an ignition coil assembly 25 and an ignition spring 24. An ignition valve shaft passage is provided at one end of the second valve cavity 132 away from the second valve port 15. The ignition fixed shaft 21 is fixed at one end of the ignition valve shaft passage away from the second valve cavity 132. The ignition moving shaft 22 is movably disposed in the ignition valve shaft passage, and one end of the ignition moving shaft 22 away from the ignition fixed shaft 21 extends into the second valve cavity 132 and is connected to the ignition sealing cap 23. The ignition sealing cap 23 is used to block the second valve port 15. The ignition coil assembly 25 is disposed in the ignition valve shaft passage and is located on the outer periphery of the ignition fixed shaft 21 and the ignition moving shaft 22. The ignition spring 24 is disposed between the ignition sealing cap 23 and the connection of the second valve cavity 132 and the ignition valve shaft passage. When the ignition coil assembly 25 is powered on, the ignition moving shaft 22 moves in the direction close to the ignition fixed shaft 21 to open the second valve port 15.

[0047] The combustion solenoid valve 3 includes a combustion fixed shaft 31, a combustion moving shaft 32, a combustion sealing cap 33, a combustion coil assembly 35 and a combustion spring 34. A combustion valve shaft passage is provided at one end of the first valve cavity 131 away from the first valve port 14. The combustion fixed shaft 31 is fixed at one end of the combustion valve shaft passage away from the first valve cavity 131. The combustion moving shaft 32 is movably disposed in the combustion valve shaft passage, and one end of the combustion moving shaft 32 away from the combustion fixed shaft 31 extends into the first valve cavity 131 and is connected to the combustion sealing cap 33. The combustion sealing cap 33 is used to block the first valve port 14. The combustion coil assembly 35 is disposed in the combustion valve shaft passage and is located on the outer periphery of the combustion fixed shaft 31 and the combustion moving shaft 32. The combustion spring 34 is disposed between the combustion sealing cap 33 and the connection of the first valve cavity 131 and the combustion valve shaft passage. When the combustion coil assembly 35 is powered on, the combustion moving shaft 32 moves in the direction close to the combustion fixed shaft 31 to open the first valve port 14.

[0048] Further, both the combustion solenoid valve 3 and the ignition solenoid valve 2 are double-coil solenoid valves. The ignition coil assembly 25 includes an ignition valve-opening coil 251 and an ignition maintaining coil 252. The ignition maintaining coil 252 is located outside the ignition valve-opening coil 251. The ignition valve-opening coil 251 has a smaller resistance, and the ignition maintaining coil 252 has a larger resistance. The combustion solenoid valve 3 includes a combustion valve-opening coil 351 and a combustion maintaining coil 352. The combustion maintaining coil 352 is located outside the combustion valve-opening coil 351. The combustion valve-opening coil 351 has a smaller resistance, and the combustion maintaining coil 352 has a larger resistance. As Figure 4As shown, during ignition, the ignition valve-opening coil 251 and the ignition-maintaining coil 252 are energized simultaneously. Since the resistance of the ignition-maintaining coil 252 is much greater than that of the ignition valve-opening coil 251, the current basically passes through the ignition valve-opening coil 251. The magnetic force generated by the current causes the ignition moving shaft 22 to move towards the ignition fixed shaft 21 and drives the ignition sealing cap 23 away from the second valve port 15, so that the ignition solenoid valve 2 is opened. Then the ignition valve-opening coil 251 is de-energized, and the ignition-maintaining coil 252 is energized. The gas enters the air outlet passage 12 through the second valve port 15. Since the area of the second valve port 15 is small, the flow rate of the gas entering the air outlet passage 12 through the second valve port 15 is small, thus avoiding deflagration during ignition. After successful ignition, as Figure 5 shown, the combustion valve-opening coil 351 and the combustion-maintaining coil 352 are energized simultaneously. After the combustion solenoid valve 3 is opened, the combustion valve-opening coil 351 is de-energized, and the combustion-maintaining coil 352 continues to be energized. At this time, the resistances of the simultaneously energized ignition-maintaining coil 252 and combustion-maintaining coil 352 are both large, and the required current is very small, saving the power consumption of the battery in the gas device and extending the service life of the battery. As Figure 6 shown, when the combustion valve-opening coil 351 is de-energized and the combustion-maintaining coil 352 continues to be energized for 0.5 s to 2 s, the ignition-maintaining coil 252 is de-energized.

[0049] In an embodiment, the axis of the air inlet passage 11 is perpendicular to the axis of the air outlet passage 12. Among the first valve cavity 131 and the second valve cavity 132, the axis of one of them is perpendicular to both the axis of the air inlet passage 11 and the axis of the air outlet passage 12, and the axis of the other is collinear with the axis of one of the air inlet passage 11 and the air outlet passage 12. Such a setting enables the air inlet passage 11, the first valve cavity 131, and the second valve cavity 132 to all surround the circumference of the air outlet passage 12, with a simple and compact structure, reducing the cost; and the flow path of the gas in the gas valve body 1 is short. After the ignition solenoid valve 2 and the combustion solenoid valve 3 are opened, the gas can quickly enter the air outlet passage 12, and the gas response speed of the water-gas linkage valve is faster.

[0050] In an embodiment, the axis of the first valve cavity 131 or the second valve cavity 132 is collinear with the axis of the air outlet passage 12. In this embodiment, the axis of the first valve cavity 131 and the axis of the air outlet passage 12 are arranged on the same straight line, so that the first valve port 14 is located at the end of the air outlet passage 12, which is more convenient for the processing of the first valve port 14 with a larger opening area. Of course, in other embodiments, the axis of the second valve cavity 132 and the axis of the air outlet passage 12 can also be arranged on the same straight line.

[0051] Further, the intake passage 11 communicates with the first valve cavity 131, such that the intake passage 11 is closer to the first valve port 14. After the fuel gas enters the valve cavity 13 through the intake passage 11, it first flows through the first valve cavity 131. After the combustion solenoid valve 3 is energized to open the first valve port 14, a large flow rate of fuel gas can quickly enter the outlet passage 12 through the first valve port 14, improving the response speed of fuel gas combustion.

[0052] Alternatively, the intake passage 11 communicates with the second valve cavity 132. With such an arrangement, the fuel gas coming out of the intake passage 11 first enters the second valve cavity 132, and then enters the first valve cavity 131 through the communication port between the second valve cavity 132 and the first valve cavity 131.

[0053] In one embodiment, the second valve cavity 132 and the first valve cavity 131 are respectively located on adjacent sides of the intake passage 11. With such an arrangement, the outlet of the intake passage 11 is closer to the communication port between the first valve cavity 131 and the second valve cavity 132. During ignition, after the fuel gas enters the valve cavity 13 through the intake passage 11, the flow path of the fuel gas from the outlet of the intake passage 11 to the second valve port 15 is shortened, improving the response speed of ignition after the ignition solenoid valve 2 is opened.

[0054] In one embodiment, the axis of the first valve cavity 131 and the axis of the second valve cavity 132 are perpendicular to each other, and the axis of the first valve cavity 131 and the axis of the second valve cavity 132 are in the same plane. With such an arrangement, the structure of the gas valve body 1 is more compact, and the axes of the first valve cavity 131 and the second valve cavity 132 are vertically intersecting, and the two are communicated at the position where the axes intersect, ensuring the smoothness of the fuel gas flowing through the first valve cavity 131 and entering the second valve cavity 132.

[0055] In one embodiment, the axis of the intake passage 11 is parallel to the axis of the outlet passage 12, and the axes of the first valve cavity 131 and the second valve cavity 132 are both perpendicular to the axis of the intake passage 11; or, the axis of one of the first valve cavity 131 and the second valve cavity 132 is perpendicular to the axis of the intake passage 11, and the axis of the other is on the same straight line as the axis of the outlet passage 12. Exemplarily, the axis of the first valve cavity 131 and the axis of the outlet passage 12 are on the same straight line, the axis of the intake passage 11 is perpendicular to the axis of the second valve cavity 132, and the outlet of the intake passage 11 communicates with the second valve cavity 132. The fuel gas enters the second valve cavity 132 from the outlet of the intake passage 11 and enters the first valve cavity 131 through the communication port between the second valve cavity 132 and the first valve cavity 131.

[0056] In one embodiment, the gas valve body 1 extends inwards to form a connecting portion 101, and the first valve port 14, the second valve port 15 and the air outlet passage 12 are arranged on the connecting portion 101. The air outlet passage 12 is partially arranged at the communication position of the first valve cavity 131 and the second valve cavity 132 in the gas valve body 1. On the one hand, the structure of the gas valve body 1 is made more compact; on the other hand, the flow path of the gas in the valve cavity 13 entering the air outlet passage 12 is shortened, and the response speed of ignition and combustion is improved.

[0057] Further, the connecting portion 101 extends inwards to the lower part of the outlet of the air inlet passage 11. When the combustion solenoid valve 3 opens the first valve port 14, the larger flow rate of gas flowing out of the outlet of the air inlet passage 11 can directly enter the air outlet passage 12 through the first valve port 14, further improving the response speed of combustion.

[0058] In one embodiment, a rim 1011 surrounding the first valve port 14 protrudes from the side wall of the connecting portion 101 towards the direction of the first valve cavity 131. The combustion solenoid valve 3 can abut against the rim 1011 to block the first valve port 14. By arranging the rim 1011 in the circumferential direction of the first valve port 14, when blocking the first valve port 14, the combustion sealing cap 33 abuts against the rim 1011. Only by ensuring the sealing performance between the combustion sealing cap 33 and the rim 1011 can the sealing performance of the first valve port 14 be ensured. The contact area between the rim 1011 and the combustion sealing cap 33 is small, reducing the processing difficulty.

[0059] In one embodiment, a flange 1012 surrounding the second valve port 15 protrudes from the side wall of the connecting portion 101 towards the direction of the second valve cavity 132. The ignition solenoid valve 2 can abut against the flange 1012 to block the second valve port 15. By arranging the flange 1012, the ignition sealing cap 23 abuts against the end face of the flange 1012, reducing the sealing area and being easier to process.

[0060] The gas-water interlocking valve provided in this embodiment can achieve the installation of two solenoid valves, namely the ignition solenoid valve 2 and the combustion solenoid valve 3, while having a simple and compact structure through the design of the internal structure of the gas valve body 1. During ignition, the second valve port 15 is opened through the ignition solenoid valve 2. The gas enters the valve cavity 13 through the intake passage 11, then enters the outlet passage 12 through the second valve port 15, and after being stabilized by the pressure stabilizing valve 4, the gas flow is adjusted by the gas valve core 5 and then enters the combustion chamber for ignition. The opening area of the second valve port 15 is designed according to the gas flow required during ignition, which can effectively avoid deflagration during ignition. Both the ignition solenoid valve 2 and the combustion solenoid valve 3 are double-coil solenoid valves. After successful ignition, the ignition opening valve coil 251 is powered off, and the ignition maintaining coil 252 continues to be powered on. Then the combustion solenoid valve 3 is powered on. After the first valve port 14 is opened, the combustion opening valve coil 351 is powered off, and the combustion maintaining coil 352 is powered on. At this time, the ignition maintaining coil 252 and the combustion maintaining coil 352 are powered on simultaneously. Since the resistances of both the ignition maintaining coil 252 and the combustion maintaining coil 352 are relatively large and the required current is small, it saves electric energy and makes the battery life of the gas device longer.

[0061] This embodiment also provides a gas device, including the above-mentioned gas-water interlocking valve. By applying the above-mentioned gas-water interlocking valve, the gas device can ensure that deflagration does not occur during startup, simplifies the structure of the gas valve body 1, makes the structure of the gas valve 100 more compact, and reduces the production cost.

[0062] In the specific content of the above specific embodiment, each technical feature can be combined arbitrarily without contradiction. For the sake of concise description, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features does not exist in contradiction, it should be considered as the scope recorded in this specification.

[0063] The specific content of the above specific embodiment only expresses several implementation manners of the present invention. Its description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
