[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] like Figure 1-3 As shown, the utility model provides a double solenoid valve low-power valve body, including a water valve body 8 and an air valve body 3 arranged side by side, the first end of the water valve body 8 is a water inlet 1, the second end of the water valve body 8 is provided with a water outlet 9, the inner side of the water outlet 9 is provided with a water valve core shaft 17, the first end of the air valve body 3 is an air inlet 2, the air valve body 3 is provided with a first air cavity 12 and a second air cavity 13, a first valve port 11 is provided between the first air cavity 12 and the air inlet 2, a first solenoid valve 4 for opening and closing the first valve port 11 is installed on the air valve body 3, and the air valve A control air cavity 16 is provided on the valve body 3 on one side of the first air cavity 12, and the control air cavity 16 is connected to the first air cavity 12 through a flow air channel 14, a second valve port 15 is provided between the control air cavity 16 and the second air cavity 13, a second solenoid valve 6 for opening and closing the second valve port 15 is installed in the control air cavity 16, a first connecting pipe 5 is provided on one side of the second air cavity 13, a second connecting pipe 7 is provided on the second end side of the water valve body 8, the first connecting pipe 5 is connected to the second connecting pipe 7 but not connected, and a total inlet 18 is provided on the first connecting pipe 5.

[0016] When in use, the water valve body 8 and the gas valve body 3 can be connected to the water pipe and the gas pipe, and the flow of water discharged from the water outlet 9 can be controlled by rotating the water valve core shaft 17. The gas entering from the air inlet 2 of the gas valve body 3 is controlled by the first solenoid valve 4 of the first valve port 11 to adjust the gas to enter the first air cavity 12. The gas entering the first air cavity 12 enters the control air cavity 16 from the flow air channel 14, and then enters the second air cavity 13 through the second solenoid valve 6 of the second valve port 15, and finally is discharged from the total inlet 18 at the end of the first connecting pipe 5 and enters the water heater.

[0017] If gas intake is to be achieved, the first solenoid valve 4 and the second solenoid valve 6 need to be energized at the same time. As long as one solenoid valve loses power or fails, the gas cannot enter the water heater, which is safer.

[0018] In order to sense the water inflow, a water flow rotor is installed inside the water valve body 8. When water enters the water inlet 1, the water flow rotor rotates axially. An inductor 10 corresponding to the position of the water flow rotor is installed on one side of the water valve body 8. A wire is arranged on the water flow rotor. When the water flow rotor rotates with the wire, it is induced by the magnetic field generated by the inductor 10. In this way, when the inductor 10 senses a signal, it means that water has entered, and the first solenoid valve 4 and the second solenoid valve 6 can be controlled to be energized to achieve synchronization of water inlet and air intake.

[0019] In order to install more compactly, the water valve body 8 and the gas valve body 3 are both L-shaped, and the second solenoid valve 6 is installed below the first connecting pipe 5 .

[0020] In this embodiment, the first solenoid valve 4 and the second solenoid valve 6 are single-channel solenoid valves or dual-channel solenoid valves, which can be selected and replaced as needed. Both the single-channel solenoid valve and the dual-channel solenoid valve are prior arts, and their working principles are well known to those skilled in the art, so they will not be elaborated here.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
