[0002] Currently, gas control valves are generally electrically driven to achieve precise flow regulation and remote automated control. However, gas is a flammable and explosive hazardous medium, making its safety control crucial. Therefore, although solenoid valves are widely used in gas control systems due to their rapid response and precise control, their dependence on power supply has become a significant safety hazard. In the event of a power outage, traditional solenoid valves may fail to close promptly due to loss of driving force, thus increasing the risk of gas leakage. Therefore, it is necessary to address the aforementioned technical issues. Summary of the Invention

The gas inlet is connected to the first cavity, and the gas outlet is connected to the second cavity. The first valve seat is disposed in the first cavity and forms a first channel connecting the first cavity and the gas pipeline. The second valve seat is disposed in the second cavity and forms a second channel connecting the second cavity and the gas pipeline. A first solenoid valve has a first valve plate, a spring and a first solenoid assembly. The spring is connected to the first valve plate and is used to press the first valve plate against the first valve seat to close the first channel.

The spring is coaxially mounted on the valve stem.

[0006] Optionally, the first electromagnetic component further includes an inner housing detachably connected to the body; The inner housing, together with the body, forms the first cavity.

[0022] Please refer to the following: Figures 1 to 5 The present application provides an integrated automatic gas control valve according to an embodiment. This integrated automatic gas control valve includes a body 100, a first solenoid valve 200, and a second solenoid valve 300. Wherein: The body 100 forms a first cavity 101, a second cavity 102, a gas inlet 103, a gas outlet 104, a gas pipeline 105, a first valve seat 106, and a second valve seat 107. The first cavity 101 and the second cavity 102 are both sealed cavities and are independent of each other. The gas inlet 103 communicates with the first cavity 101, and the gas outlet 104 communicates with the second cavity 102. The first valve seat 106 is disposed within the first cavity 101 and forms a first channel 108 connecting the first cavity 101 and the gas pipeline 105. The second valve seat 107 is disposed within the second cavity 102 and forms a second channel 109 connecting the second cavity 102 and the gas pipeline 105. The first solenoid valve 200 has a first valve plate 201, a spring 202, and a first electromagnetic assembly. The spring 202 is connected to the first valve plate 201 and is used to press the first valve plate 201 against the first valve seat. The first channel 108 is closed on the first solenoid valve 106. The first solenoid component is driven to the first valve plate 201 and is used to drive the first valve plate 201 away from the first valve seat 106. The second solenoid valve 300 has a second valve plate 301 and a second solenoid component. The second solenoid valve 300 is driven to the second valve plate 301 and is used to drive the second valve plate 301 to move closer to or away from the second valve seat 107 to close or open the second channel 109. Here, the first valve seat 106 can be set as an installation type like the second valve seat 107, or it can be set as an integral type. In this embodiment, an integral structure is preferred, that is, the first valve seat 106 and the body 100 are an integral structure. The body 100 can be obtained by casting process, and then the first cavity 101 is processed by machining process. The first valve seat 106 is integrally processed when processing the first cavity 101.

[0023] According to the structure provided in this embodiment, the integrated automatic gas control valve provided in this embodiment is provided with a first solenoid valve 200 and a second solenoid valve 300, wherein the first solenoid valve 200 is provided with a spring 202 connected to the first valve plate 201. When a power failure occurs and the first solenoid valve 200 and the second solenoid valve 300 lose their electromagnetic driving force, the first spring 202 connected to the first valve plate 201 can automatically push the first valve plate 201 against the first valve seat 106 and close the first channel 108. In this way, the connection channel between the gas inlet 103 and the gas outlet 104 is cut off accordingly, so that gas leakage will not occur. Under normal operating conditions, the first electromagnetic component in the first solenoid valve 200 can drive the first valve plate 201 to overcome the elastic force of the spring 202 and open the first channel 108. In this way, the second electromagnetic component can drive the second valve plate 301 to move closer to or away from the second valve seat 107 to close or open the second channel 109, thereby achieving the technical effect of precise control of gas flow. Therefore, the integrated automatic gas control valve provided in this embodiment has the characteristics of fast response and precise control, and can also achieve a good safety protection effect, which is far superior to the existing technology.

[0024] Here, please refer to the key points. Figures 6 to 8 Two second chambers 102 can also be arranged side-by-side in the gas pipeline 105 and the gas outlet 104. Correspondingly, two second valve seats 107, two second valve plates 301, and two second solenoid valves 300 are also provided. In this way, a large flow of gas can be output while maintaining high sensitivity through the cooperation of two second solenoid valves 300. The principle of maintaining high sensitivity is that, with the same gas outlet 104, by using two second solenoid valves 300 to control the action of two second valve plates 301 respectively, the size of the second valve plate 301 can be reduced. Correspondingly, the size of other moving parts connected to the second valve plate 301, such as valve stems, can also be reduced, thereby reducing the weight of the moving parts. This effectively reduces the inertia of the moving parts. Thus, when the second solenoid valve 300 drives the second valve plate 301, the hysteresis phenomenon can be reduced, thereby achieving high sensitivity.

[0025] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5The first electromagnetic component includes a magnetic core 203, a coil 204, and a valve stem 205. The coil 204 is configured to cooperate with the magnetic core 203 and is used to drive the valve stem 205. The valve stem 205 is coaxially configured with the magnetic core 203, and a first valve plate 201 is connected to the end of the valve stem 205 away from the magnetic core 203. A spring 202 is coaxially mounted on the valve stem 205. According to the structure provided in this embodiment, when the coil 204 is energized, it can drive the magnetic core 203 to move, thereby driving the valve stem 205 connected to the magnetic core 203 and the first valve plate 201 connected to the valve stem 205 to move. Since the spring 202 is also coaxially mounted on the valve stem 205, the valve stem 205 can act as a guide structure for the spring 202, allowing the spring 202 to extend and retract stably. This makes the process of the spring 202 driving the first valve stem 205 to move more stable and helps to further improve the safety protection performance of the integrated automatic gas control valve in this embodiment.

According to the structure provided in this embodiment, the inner housing 206 detachably connected to the body 100 facilitates the disassembly, assembly, and maintenance of the first solenoid valve 200. On the other hand, it also improves the movement stability of the magnetic core 203 and the valve stem 205.

According to the structure provided in this embodiment, the connecting flange plate 207 detachably connected to the body 100 can significantly improve the installation stability of the inner housing 206 by cooperating with the body 100 to clamp the inner housing 206, which is beneficial for further improving the safety protection performance of the integrated automatic gas control valve in this embodiment.

[0028] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5The first electromagnetic component also includes an intermediate housing 208. The intermediate housing 208 forms a cavity for accommodating the coil 204 and a hook 209 for passing through the connecting flange plate 207. The connecting flange plate 207 is correspondingly provided with a snap-fit ​​hole 210 for the hook 209 to pass through. The intermediate housing 208 is detachably connected to the connecting flange plate 207 through the mutual cooperation of the hook 209 and the snap-fit ​​hole 210. According to the structure provided in this embodiment, the intermediate housing 208 can be stably snapped onto the connecting flange plate 207 through the mutual cooperation of the hook 209 and the snap-fit ​​hole 210. Since the coil 204 is located inside the intermediate housing 208 and supported by the intermediate housing 208, the intermediate housing 208 snapped onto the connecting flange plate 207 not only facilitates the disassembly, assembly, and maintenance of the coil 204, but also significantly improves the installation stability of the coil 204. This is beneficial to further improve the safety protection performance of the integrated automatic gas control valve in this embodiment.

[0029] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The first electromagnetic component also includes an injection-molded housing 211; an intermediate housing 208 is disposed inside the injection-molded housing 211 and has a perforated groove 212, which connects to the cavity in the intermediate housing 208 used to accommodate the coil 204. According to the structure provided in this embodiment, during the injection molding process, the injection-molded housing 211 can fill the space between the coil 204 and the intermediate housing 208 through the perforated hole on the intermediate housing 208. This further improves the installation stability of the coil 204, thereby further enhancing the safety performance of the integrated automatic gas control valve in this embodiment.

[0030] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The first electromagnetic component also includes a sealing ring 213; the sealing ring 213 is disposed between the inner housing 206 and the body 100.

According to the structure provided in this embodiment, the recessed platform 110 formed on the body 100 can enable the inner housing 206 to maintain better positional stability, which is beneficial to further improving the safety protection performance of the integrated automatic gas control valve in this embodiment.

[0032] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 5 The second valve seat 107 is detachably connected to the body 100. According to the structure provided in this embodiment, since the second valve seat 107 is used to cooperate with the second valve plate 301 to achieve the precise adjustment effect of the integrated automatic gas control valve in this embodiment, the second valve seat 107 will frequently contact the second valve plate 301 and is prone to wear. Therefore, the second valve seat 107, which is detachably connected to the body 100, can be easily replaced, thereby enabling the integrated automatic gas control valve provided in this embodiment to achieve a long-term precise adjustment effect.

This not only helps to further improve the precise adjustment effect of the integrated automatic gas control valve in this embodiment, but also allows operators to more accurately judge gas leaks, thereby further improving the safety protection performance of the integrated automatic gas control valve in this embodiment.
