Description

Technical Field

[0001] This utility model relates to the field of gas self-closing valve technology, specifically an Internet of Things gas self-closing valve. Background Technology

[0002] A gas pipeline self-closing valve, or simply self-closing valve, is a device installed on low-pressure gas pipelines that automatically closes without electricity or other external power when the gas supply pressure is low or high, and can only be manually opened.

[0003] While current gas shut-off valves can prevent low-pressure gas leaks, they also present some inconveniences in use. For example, they can only cut off gas pipelines in cases of underpressure or overpressure, but they cannot effectively cut off pipelines with minor leaks. Furthermore, existing gas shut-off valves will activate when pipeline pressure fluctuates, but because they are purely mechanical, the gas pipeline is only shut off by the position of the valve's operating handle. The handle is small, and the difference between disconnection and continuity is not significant. This makes it difficult for older people to quickly detect when the gas shut-off valve is closed, which affects their gas usage. Utility Model Content

The self-closing mechanism includes a spring, a rubber diaphragm, an iron sheet, a connecting bucket, a magnetic ring, a moving rod, and a sealing plate. The connecting bucket is fixedly installed inside the housing. The connecting bucket divides the shell into upper and lower cavities. The air outlet on the side of the connecting bucket extends to the outside of the shell. The lower end of the connecting bucket is columnar and connects to the bottom of the shell. The top of the connecting bucket is fixedly connected to the bottom edge of the rubber diaphragm. An iron plate is fixedly installed in the middle of the top of the rubber diaphragm.

Thus, the gas self-closing valve can automatically cut off the gas pipeline even in the event of a slight leak, avoiding the hazards caused by gas leakage. In addition, when the pressure fluctuates in the gas pipeline and the gas self-closing valve is activated, the push plate will trigger the micro switch and send the signal of gas pipeline cut-off to the smart device through the Internet of Things module, so that the smart device will issue a prompt, making it easy for people to quickly discover that the gas self-closing valve has cut off the gas pipeline and making it convenient to use.

A lifting mechanism 6 that cooperates with the self-closing mechanism 4 is installed on the top of the housing 1. A sealing barrel 7 is fixedly installed on the top of the housing 1. The sealing barrel 7 is located outside the lifting mechanism 6. A combustible gas monitoring module 13 is fixedly installed on the top of the sealing barrel 7. The combustible gas monitoring module 13 is electrically connected to the control module 3. Three colored LED beads 9 are fixedly installed on the top of the sealing barrel 7. The colors of the three colored LED beads 9 are red, green and orange, respectively. LED 9 is electrically connected to control module 3. The colored LED 9 can display different states of the gas self-closing valve, such as green LED when connected, red LED when overpressure is present, and orange LED when low pressure is present. This allows people to quickly judge the status of the self-closing valve and makes it easy to use. When the pressure in the gas pipeline fluctuates and the gas self-closing valve is activated, push plate 5 will trigger micro switch 8 and send the gas pipeline cut-off signal to smart device through IoT module 2, so that smart device will issue an alarm sound, making it easy for people to quickly discover that the gas self-closing valve has cut off the gas pipeline and making it easy to use.

[0021] The self-closing mechanism 4 includes a spring 41, a rubber diaphragm 42, an iron sheet 43, a connecting bucket 44, a magnetic ring 45, a moving rod 46, and a sealing plate 47. The connecting bucket 44 is fixedly installed inside the housing 1, dividing the housing 1 into upper and lower cavities. The air outlet on the side of the connecting bucket 44 extends to the outside of the housing 1. The lower end of the connecting bucket 44 is columnar and connects to the bottom of the housing 1. The top of the connecting bucket 44 is fixedly connected to the bottom edge of the rubber diaphragm 42. An iron sheet 43 is fixedly installed in the middle of the top of the rubber diaphragm 42. The upper side of the columnar part of the connecting bucket 44 is fixedly connected to the inner side of the magnetic ring 45. The magnetic ring 45 cooperates with the iron sheet 43. The middle of the top of the sealing plate 47 is fixedly connected to the lower end of the moving rod 46. The top of the housing 1 is fixedly connected. A guide cylinder 11 is installed, which is sleeved on the outside of the moving rod 46. The guide cylinder 11 provides guidance for the moving rod 46 and the push plate 5, improving their stability during movement. The sealing plate 47 cooperates with the air inlet at the bottom of the connecting bucket 44. A rubber pad 12 is fixedly installed on the top of the sealing plate 47. The rubber pad 12 cooperates with the air inlet at the bottom of the connecting bucket 44. The rubber pad 12 improves the sealing performance when the sealing plate 47 contacts the connecting bucket 44, preventing air leakage under overpressure. The iron sheet 43 is fixedly installed on the moving rod 46. The upper end of the moving rod 46 passes through the through hole at the top of the housing 1 and is fixedly connected to the middle of the bottom of the push plate 5. The top of the push plate 5 is fixedly connected to one end of the pull rod 10. The other end of the pull rod 10 passes through the through hole at the top of the sealing bucket 7 and extends... Extending to the outside, the push plate 5 can be manually pulled by the pull rod 10 to manually operate the self-closing valve. The two ends of the spring 41 are fixedly connected to the top of the iron plate 43 and the top of the housing 1, respectively. The lifting mechanism 6 includes a motor 61, a lead screw 62, a fixed plate 63, a push-pull plate 64, a moving block 65, and a guide plate 66. The fixed plate 63 is L-shaped and is fixedly installed on one side of the top of the housing 1. The top of the fixed plate 63 and the top of the housing 1 are rotatably connected to the two ends of the lead screw 62. One end of the lead screw 62 passes through the threaded hole at the top of the moving block 65. The side of the moving block 65 is fixedly connected to the side of the U-shaped push-pull plate 64. The push-pull plate 64 cooperates with the push plate 5. The motor 61 is fixedly installed on the top of the fixed plate 63. The output shaft passes through the through hole at the top of the fixed plate 63 and is fixedly connected to the upper end of the lead screw 62. A guide plate 66 is fixedly installed on the side of the fixed plate 63. The guide plate 66 is located in the groove on the side of the moving block 65. Microswitches 8 are fixedly installed at the top and bottom of the push-pull plate 64. The two microswitches 8 cooperate with the push plate 5. The motor 61 and the microswitches 8 are electrically connected to the control module 3. The combustible gas monitoring module 13 can monitor the air near the housing 1. If combustible gas is detected, the control module 3 will automatically control the motor 61 to work and drive the lead screw 62 to rotate. The lead screw 62 drives the moving block 65 and the push-pull plate 64 to move. The push-pull plate 64 drives the push plate 5 and the moving rod 46 to move. The moving rod 46 drives the sealing plate 47 to move.The sealing plate 47 seals the bottom of the connecting hopper 44, cutting off the gas pipeline. This allows the gas self-closing valve to automatically cut off the gas pipeline even in the event of a minor leak, preventing hazards caused by gas leaks. The working principle of this invention is as follows: The gas pipeline is connected to the inlet and outlet on the housing 1. When an external power source is connected, the pressure inside the housing 1 decreases when a gas leak occurs. At this time, the elasticity of the spring 41 pushes the iron plate 43 downwards, causing the iron plate 43 to move the rubber diaphragm 42 downwards. This causes the magnetic ring 45 to attract the iron plate 43, sealing the inlet of the connecting hopper 44 with the rubber diaphragm 42, thus cutting off the gas pipeline. During the downward movement of the iron plate 43, it drives the moving rod 46 to move, causing the moving rod 46 to... When the push plate 5 moves downwards and the rubber diaphragm 42 contacts the air inlet on the connecting hopper 44, the push plate 5 triggers a micro switch. At this time, the control module 3 automatically controls one of the colored LED beads 9 to work, causing the colored LED bead 9 to emit a red light to remind people that the gas pressure is low. At the same time, the control module 3 will send gas pressure alarm information to the user's smart device through the Internet of Things communication module 2 to promptly remind people. Conversely, when the pressure in the gas pipeline increases, the pressure inside the housing 1 will increase. At this time, the gas pressure will push the rubber diaphragm 42 and the iron plate 43 upwards. The iron plate 43 moves the moving rod 46 upward, causing the moving rod 46 to move the sealing plate 47 upward to contact the bottom of the connecting hopper 44, sealing the connecting hopper 44 and thus cutting off the gas pipeline. Simultaneously, the push plate 5 moves upward, triggering the upper microswitch 8. The control module 3 then controls the orange LED 9 to light up, alerting people to gas overpressure. When neither microswitch 8 is triggered, the green LED 9 lights up, indicating that the gas pipeline is clear. During use, if the combustible gas monitoring module 13 detects combustible gas, the control module 3 will... The automatic control motor 61 operates, causing its output shaft to drive the lead screw 42 to rotate. The lead screw 42 then moves the moving block 65, which in turn moves the push-pull plate 64 downwards along the guide plate 66. The push-pull plate 64 pushes the push plate 5 downwards, causing the push plate 5 to move the moving rod 46 and the iron plate 43 downwards. This seals the air inlet of the connecting bucket 44 with the iron plate 43 and the rubber diaphragm 42, cutting off gas supply. Simultaneously, a red light illuminates, and the control module 3 sends an alarm signal to the smart device via the IoT communication module 2, alerting people to a gas leak. The combustible gas monitoring module 13 operates on the principle of electrochemical reaction for gas detection. When combustible gas in the air comes into contact with the sensor electrodes, an electrochemical reaction occurs, generating a change in current or voltage. By measuring the change in current or voltage between the electrodes, the concentration of combustible gas can be determined. The circuit connection involved in this invention is a conventional method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to widely used existing technology.
