[0038] The following is in conjunction with the appendix Figures 1-10 The present invention will be further described in detail with reference to specific embodiments, but this is not intended to limit the present invention.

[0039] Example 1

[0040] A gas valve includes a valve body 1 and a control component. The control component includes a housing 2 and a button module 3, a display module 4, and a control module 5 installed inside the housing 2. The control module 5 can be a microcontroller chip. The valve body 1 can be a solenoid valve or other electrically controlled valve suitable for gas pipelines. The display module 4 is used to display the user's specific operations and the data of the valve body 1. The user sends operation commands to the control module 5 through the button module 3. The control module 5 processes the commands and then sends control commands to the valve body 1, thereby controlling the valve body 1 and displaying the operation information through the display module 4. The valve body 1, button module 3, and display module 4 are all electrically connected to the control module 5. A cover 6 is provided on one side of the housing 2. A PCB circuit board 10 is provided in the housing 2. The button module 3 and the control module 5 are both mounted on the PCB circuit board 10. The cover 6 is provided with a transparent window 61, which is correspondingly set to the display module 4. The display screen of the display module 4 faces the transparent window 61. This setting can ensure the normal display of the display module 4 and also protect the display module 4. By setting up display module 4, a visual operation interface can be provided to users, improving the intuitiveness and ease of operation of gas valve control.

[0041] In this embodiment, the cover 6 is also provided with at least one button 62, which is electrically connected to the button module 3. The button 62 is used to respond to the user's touch operation and generate a capacitance change signal. The button module 3 converts the capacitance change signal into a digital button event, and the control module 5 receives the button event and generates a corresponding control command. The housing 2 and the cover 6 are closed to form a sealed chamber. The PCB circuit board 10 and the display module 4 are arranged adjacent to each other in the sealed chamber. By setting the button 62 on the outside of the cover 6, both control requirements and waterproofing can be ensured. The control module 5 is also electrically connected to a communication module and a timing module. The communication module can be a WIFI module or a 5G communication module. A pressure detection module is installed on the gas pipeline, and the information is sent out wirelessly. The communication module of the gas valve receives this information and sends it to the control module 5. The control module 5 processes the information and displays it on the display module 4. The buttons 62 include a valve on / off button, a timing button, a detection button, a clear button, and a confirmation button. Users can use different buttons to control the valve body 1 in different ways. Pressing the detection button will cause the control module 5 to execute the gas leak procedure, thereby sending a disconnect signal to the valve body 1 to check whether the valve body 1 can close normally. It also sends a gas leak signal through the communication module. Other mechanisms in the pipeline will execute a warning procedure after receiving the signal, that is, start the gas leak handling steps. This setting can help users to find damaged parts in time and replace them in time to avoid danger in the event of a gas leak.

[0042] In this embodiment, the gas valve also includes a bracket 7. The housing 2 is mounted on one side of the bracket 7, and a panel 8 is mounted on the other side of the bracket 7. The surface of the panel 8 is provided with a display area 81 and a button area 82. The display area 81 is correspondingly arranged with the display module 4, and the button area 82 is correspondingly arranged with the buttons 62. The panel 8 is a glass panel. The button area 82 includes multiple through holes, each corresponding to a button. This arrangement facilitates the user's button pressing. Protective tape can be laid on the outside of the through holes to prevent impurities from entering the housing 2 through the through holes. At the same time, button markings can be printed on the tape. The display area 81 is partially transparent glass to facilitate the display module 4 to display content. The display screen of the display module 4 faces the display area 81. In some other embodiments, the button area 82 can be a glass panel without through holes, and the corresponding buttons 62 need to be configured as non-contact buttons such as capacitive buttons or inductive buttons.

[0043] Example 2

[0044] The difference between this embodiment and Embodiment 1 is that the surface of the bracket 7 has multiple perforations 71, the side of the bracket 7 has multiple connection holes 72, and the interior of the bracket 7 has a chamber 73, which is connected to the perforations 71 and the connection holes 72 respectively. This design is used for gas dispersion. After the valve body 1 is installed, it will be isolated from the outside. By setting the perforations 71 and the connection holes 72, the outside of the valve body 1 can be connected to the outside, preventing the accumulation of micro-leaked natural gas concentration and avoiding deflagration.

[0045] In this embodiment, the housing 2 and the cover 6 are connected. In some embodiments, the housing 2 and the cover 6 are fixed by ultrasonic welding; in other embodiments, two first connectors 21 are provided on the outer side of the housing 2, and the two first connectors 21 are respectively disposed opposite to each other on both sides of the housing 2. The outer side of the cover 6 is provided with a second connector 63 that matches the first connectors 21. The first connectors 21 are respectively connected to the second connectors 63 and the bracket 7. The first connectors 21 are connected to the second connectors 63 and the bracket 7 by screws. This arrangement allows the cover 6 to be fixed to the housing 2, and also allows the housing 2 to be fixed to the bracket 7.

[0046] In this embodiment, the surface of the housing 2 is provided with a first interface 22 and a first sealing cover 23 covering the first interface 22. The first interface 22 is electrically connected to the control module 5 and the valve body 1 respectively. A first sealing ring 24 is provided between the first sealing cover 23 and the housing 2. The side of the first sealing cover 23 has a first opening 231. The surface of the valve body 1 is provided with a second interface 11 and a second sealing cover 12 covering the second interface 11. The second interface 11 is electrically connected to the first interface 22 and the valve body 1 respectively. The first interface 22 and the second interface 11 are electrically connected through a ribbon cable 9. A second sealing ring 13 is provided between the second sealing cover 12 and the valve body 1. The side of the second sealing cover 12 has a second opening 121. One end of the ribbon cable 9 enters the first sealing cover 23 through the first opening 231 and is then electrically connected to the first interface 22. The first sealing ring 24 is a rubber ring. The first sealing cover 23 presses the ribbon cable 9 onto the first sealing ring 24, which deforms to allow the ribbon cable 9 to pass through normally. This design reduces the gap between the first sealing cover 23 and the housing 2, enhancing the sealing effect of the first sealing cover 23 on the first interface 22. The other end of the ribbon cable 9 enters the second sealing cover 12 through the second opening 121 and is then electrically connected to the second interface 11. The second sealing ring 13 is also a rubber ring. The second sealing cover 12 presses the ribbon cable 9 onto the second sealing ring 13, which deforms to allow the ribbon cable 9 to pass through normally. This design reduces the gap between the second sealing cover 12 and the valve body 1, enhancing the sealing effect of the second sealing cover 12 on the second interface 11. Sealant can be applied between the first sealing cover 23 and the housing 2, and between the second sealing cover 12 and the valve body 1, to enhance the sealing effect of the housing 2 and the valve body 1.

[0047] In this embodiment, an annular groove 25 is provided around the opening of the housing 2, and a third sealing ring 26 is embedded in the annular groove 25. The third sealing ring 26 is disposed between the housing 2 and the cover 6. The third sealing ring 26 is a rubber ring. By providing the third sealing ring 26, the sealing effect between the housing 2 and the cover 6 can be enhanced. Sealant can be applied between the housing 2 and the cover 6 to enhance the sealing effect of the housing 2.

[0048] In this embodiment, a placement platform 27 and a support column 28 are arranged adjacent to each other inside the housing 2. The display module 4 is placed on the placement platform 27, and one end of the support column 28 abuts against the side of the display module 4 away from the cover 6. Both the placement platform 27 and the support column 28 are used to support the display module 4. This arrangement allows the display module 4 to be placed stably inside the housing 2, making it convenient for the user to observe.

[0049] In this embodiment, a first limiting block 271 and a second limiting block 272 are disposed opposite each other on the surface of the placement platform 27. A notch 281 is provided at one end of the support column 28. The side of the notch 281, the side of the first limiting block 271, and the side of the second limiting block 272 all abut against the side of the display module 4. The first limiting block 271, the second limiting block 272, and the support column 28 are arranged sequentially around the outside of the display module 4. This arrangement can fix the display module 4 and prevent the display module 4 from shaking.

[0050] In this embodiment, the surface of the housing 2 has a first annular groove 29 surrounding the first interface 22, and the first sealing ring 24 is embedded in the first annular groove 29. By providing the first annular groove 29, the first sealing ring 24 can be prevented from shifting, thus ensuring a sealing effect.

[0051] In this embodiment, the surface of the valve body 1 has a second annular groove 14 surrounding the second interface 11, and the second sealing ring 13 is embedded in the second annular groove 14. By providing the second annular groove 14, the displacement of the second sealing ring 13 can be prevented, ensuring the sealing effect.

[0052] In this embodiment, a battery compartment 20 is provided on the side of the housing 2, and a battery pack 201 is provided in the battery compartment 20. The battery compartment 20 is covered with a battery cover, which is detachably connected to the housing 2 by screws.
