[0031] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0032] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0033] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0034] The embodiment of the present utility model provides a valve body assembly, such as Figure 1-5 As shown, it includes a first tube body 100 arranged horizontally, a second tube body 200 arranged vertically, and an electrically controlled valve body 300. The lower end of the second tube body 200 is connected to one end of the first tube body 100, and the electrically controlled valve body 300 is located above the first tube body 100 and connected to the second tube body 200. This fully utilizes the space above the first tube body 100, making the structural layout more compact and reasonable, and allowing the electrically controlled valve body 300 to be larger in size to adapt to usage scenarios with higher gas flow rates.

[0035] The first tube body 100 has a first connecting channel 110 and a fourth connecting channel 120. A gas inlet 111 communicating with the first connecting channel 110 and a gas outlet 121 communicating with the fourth connecting channel 120 are formed on the surface of the first tube body 100. Gas enters the first connecting channel 110 through the gas inlet 111, and gas in the fourth connecting channel 120 flows out through the gas outlet 121. The second tube body 200 has a second connecting channel 210 and a third connecting channel 220. The second connecting channel 210 communicates with the first connecting channel 110, and the fourth connecting channel 120 communicates with the third connecting channel 220. The electrically controlled valve body 300 is used to control the connection and disconnection between the second connecting channel 210 and the third connecting channel 220. When the second connecting channel 210 is connected to the third connecting channel 220, the gas inlet 111, the first connecting channel 110, the second connecting channel 210, the third connecting channel 220, the fourth connecting channel 120, and the gas outlet 121 are sequentially connected, and gas can enter from the gas inlet 111 and then be output from the gas outlet 121. When the second connecting channel 210 is disconnected from the third connecting channel 220, gas cannot be output from the gas outlet 121, and the electronically controlled valve body 300 can perform its basic function of controlling the on / off of the gas circuit.

[0036] It should be noted that, in this embodiment, the transverse direction may be parallel to the horizontal direction, and the vertical direction may be the vertical direction.

[0037] In some embodiments, the second tube body 200 is provided with a valve body cavity 230. The inner wall of the valve body cavity 230 is provided with a first opening 231 communicating with the second connecting channel 210 and a second opening 232 communicating with the third connecting channel 220. The electrically controlled valve body 300 includes a valve head 310 located within the valve body cavity 230 and a valve assembly 320 for driving the valve head 310 to move. The valve assembly 320 is used to control the valve head 310 to cover or open the first opening 231. When the valve head 310 covers the first opening 231, the second connecting channel 210 is unable to communicate with the valve body cavity 230, and the second connecting channel 210 and the third connecting channel 220 are disconnected. When the valve head 310 opens the first opening 231, the second connecting channel 210 communicates with the valve body cavity 230, and the second connecting channel 210 and the third connecting channel 220 are connected. Therefore, the valve head 310 is used to control the connection or disconnection of the second connecting channel 210 and the third connecting channel 220.

[0038] In other embodiments, the valve assembly 320 is used to control the valve head 310 to cover or open the second opening 232. When the valve head 310 covers the second opening 232, the third connecting channel 220 cannot communicate with the valve body cavity 230, and the second connecting channel 210 and the third connecting channel 220 are disconnected. When the valve head 310 opens the second opening 232, the third connecting channel 220 communicates with the valve body cavity 230, and the second connecting channel 210 and the third connecting channel 220 are connected. The valve head 310 can also be used to control the second connecting channel 210 and the third connecting channel 220 to be connected or disconnected.

[0039] In the above embodiment, the moving direction of the valve head 310 is parallel to the horizontal direction, which is the same as the extension direction of the first tube body 100, so that the entire electric control valve body 300 extends in the horizontal direction to occupy as much space as possible directly above the first tube body 100, reducing the occupation of the upper space on both sides of the first tube body 100. This layout is more conducive to the selection of a larger size for the electric control valve body 300.

[0040] In the above embodiment, the electrically controlled valve body 300 may be a solenoid valve, and the specific structure of the valve assembly 320 thereof is already in the prior art and will not be described in detail here.

[0041] In some embodiments, the gas inlet 111 is arranged on the end face of the first tube body 100 away from the second tube body 200 to facilitate docking with the air flow pipeline on the valve seat. The gas outlet 121 is arranged on the side of the first tube body 100 to avoid the valve seat on the end face of the first tube body 100, leaving enough space for installing other pipelines, thereby transporting the gas to other pipelines.

[0042] In some embodiments, the first connecting channel 110 and the fourth connecting channel 120 both extend in the transverse direction, and their extension directions are the same as the extension direction of the first tube body 100. The first connecting channel 110 and the fourth connecting channel 120 do not interfere with each other, and the width of the first tube body 100 can be reduced to make the air path structure more compact.

[0043] Furthermore, the fourth connecting channel 120 extends through the end face of the first tube body 100 near the second tube body 200. This facilitates drilling a hole in the end face of the first tube body 100 to form the fourth connecting channel 120, and facilitates the processing and molding of the fourth connecting channel 120. After the fourth connecting channel 120 is formed, the opening of the fourth connecting channel 120 at the end face of the first tube body 100 is sealed with a first plug 410 to prevent gas leakage.

[0044] In some embodiments, the second connecting channel 210 and the third connecting channel 220 both extend vertically, and their extension directions are the same as the extension direction of the second tube body 200. The second connecting channel 210 and the third connecting channel 220 do not interfere with each other, and the width of the second tube body 200 can be reduced to make the air path structure more compact.

[0045] Furthermore, both the second connecting channel 210 and the third connecting channel 220 penetrate the top surface of the second tube body 200, which facilitates punching holes in the top surface of the second tube body 200 to form the second connecting channel 210 and the third connecting channel 220, and facilitates the processing and forming of the second connecting channel 210 and the third connecting channel 220. After the second connecting channel 210 and the third connecting channel 220 are formed, the openings of the second connecting channel 210 and the third connecting channel 220 on the top surface of the second tube body 200 are covered with a second plug 420 to prevent gas leakage.

[0046] The embodiment of the present utility model provides a water-gas linkage valve, such as Figure 6 As shown, it includes a gas valve assembly and a water valve assembly. The gas valve assembly includes a gas valve body 500 and a valve body assembly of any of the above-mentioned embodiments. For detailed descriptions of the valve body assembly, please refer to the above-mentioned embodiments and will not be repeated here. The gas valve body 500 is provided with an air flow pipeline 510. One end of the air flow pipeline 510 forms an air inlet on the surface of the gas valve body 500, and the other end is connected to the gas inlet. This structure can fully utilize the space above the first tube body 100, and the structural layout is more compact and reasonable, so that the electronically controlled valve body 300 can be selected in a larger size to adapt to usage scenarios with larger gas flow rates.

[0047] When the second connecting channel is connected to the third connecting channel, the gas flow line 510, the gas inlet, the first connecting channel, the second connecting channel, the third connecting channel, the fourth connecting channel, and the gas outlet are sequentially connected, and gas can enter through the gas inlet and exit through the gas outlet. When the second connecting channel is disconnected from the third connecting channel, gas cannot exit through the gas outlet.

[0048] In some embodiments, a solenoid valve 520 may also be provided in the airflow pipeline 510. The solenoid valve 520 and the electrically controlled valve body 300 may both control the conduction or disconnection of the airflow pipeline 510. This may avoid the problem of a single valve body failing and being unable to disconnect the airflow pipeline 510, thereby improving reliability and safety.

[0049] In some embodiments, a first regulating valve 530 may be further provided in the air flow pipeline 510 . The first regulating valve 530 may adjust the opening of the air flow pipeline 510 , thereby controlling the flow rate of the gas.

[0050] In some embodiments, as Figure 6 and Figure 7 As shown, the water valve assembly includes a water valve body 600, a magnetic float 620, a magnetic switch 630, and a water flow sensor 640. The water valve body 600 is provided with a water flow pipeline 610 through which water flows. The magnetic float 620 and the water flow sensor 640 are both disposed in the water flow pipeline 610. The water flow sensor 640 is used to detect the water flow in the water flow pipeline 610. The magnetic switch 630 is fixed to the water valve body 600 and can be triggered by the magnetic float 620.

[0051] When the water level in the water flow pipe 610 exceeds a certain value, the magnetic float 620 will float, thereby triggering the magnetic control switch 630. When the water-gas linkage valve of this embodiment is used, the electric control valve body 300, the magnetic control switch 630, and the water flow sensor 640 are all connected to a corresponding controller. The controller determines whether the water flow detected by the water flow sensor 640 is greater than the set value and whether the magnetic control switch 630 is triggered. When the magnetic control switch 630 is triggered and the water flow detected by the water flow sensor 640 is greater than the set value, it indicates that water is flowing in the water flow pipe 610. The controller then controls the electric control valve body 300 to open the air flow pipe 510, and the corresponding burner can start combustion. Compared with the existing technology, this embodiment can reduce the risk of mis-opening the air flow pipe due to the mis-activation of the magnetic control switch 630, thereby improving the safety of use.

[0052] In some embodiments, a second regulating valve 650 may be further provided in the water flow pipeline 610 . The second regulating valve 650 may adjust the opening of the water flow pipeline 610 , thereby controlling the flow rate of water.
