Description

Technical Field

[0001] This utility model relates to liquefied gas valves, specifically to an intelligent control valve with an automatic locking mechanism to prevent gas leakage. Background Technology

[0002] In the use of liquefied petroleum gas (LPG), valves are the core hub for controlling the flow of gas, and their performance directly affects the safety of users' lives and property.

[0003] Currently, most liquefied petroleum gas (LPG) valves on the market use a mechanical transmission structure with a handwheel operated manually to achieve opening and closing functions. After long-term, high-frequency use, this traditional design will gradually cause the sealing structure inside the valve body to show signs of aging, such as wear on the sealing surface and hardening and cracking of the rubber sealing ring, due to multiple factors such as mechanical friction, media corrosion, and changes in ambient temperature and humidity.

[0004] Especially in the complex environment of a kitchen with high temperature and humidity, the aging rate of seals is significantly accelerated, causing gaps to appear in the originally tightly sealed structure, resulting in loosening and displacement of the sealing ring. Once the seal fails, colorless and odorless but flammable and explosive liquefied petroleum gas will quietly escape, not only wasting energy, but also potentially accumulating in the confined space to form a flammable mixture. When exposed to open flames or electrical sparks, this mixture can easily cause violent explosions and serious fires, posing a huge threat to home and public safety.

[0005] Moreover, when leaks occur, they often require manual detection and valve closure in a timely manner. Failure to address the issue promptly can easily lead to safety accidents. Furthermore, traditional valves lack automatic locking and emergency response mechanisms, making it impossible to respond quickly enough to stop leaks in the event of a sudden leak, thus compromising their safety. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an intelligent control valve with an automatic locking mechanism to prevent gas leakage, thereby solving the problem that existing liquefied gas valves are prone to leakage and cannot automatically lock and close when leakage occurs.

[0007] To solve the above technical problems, the present invention is achieved through the following solution: The present invention provides an intelligent control valve with an automatic locking mechanism to prevent air leakage, comprising a valve body, a clamping nut connected to the upper end of the valve body, a valve stem extending from the valve body and the clamping nut and controlling the opening and closing of the valve air passage by rotation, and a handwheel installed on the outer end of the valve stem and capable of controlling the rotation of the valve stem, wherein an annular cavity is formed between the handwheel and the clamping nut;

[0008] The intelligent control valve also includes an automatic locking mechanism to prevent air leakage, which includes:

[0009] A component that is fitted and fixed to the clamping nut and is non-rotatable;

[0010] A power mechanism installed in the annular cavity and fixed to the handwheel has a power source and a rotating component driven by the power source. The rotating component and the component are connected by friction or meshing. The rotating component moves around the component due to the thrust generated by its self-rotation.

[0011] Furthermore, the power source is an electric motor.

[0012] Furthermore, when the rotating component and the member are meshed, the member is a fixed gear and the rotating component is a moving gear.

[0013] Furthermore, a rechargeable battery pack is also installed inside the annular cavity;

[0014] The battery pack housing is equipped with a circuit board, which is electrically connected to the battery pack. The circuit board is also equipped with a charging interface and an indicator light, which are visible from the side of the handwheel.

[0015] Furthermore, the circuit board is also equipped with a one-button call button, which is visible and operable on the side of the handwheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model is equipped with an automatic locking mechanism, which can automatically trigger and close the valve when a liquefied gas leak occurs, effectively preventing the leak and improving the safety of liquefied gas use.

[0018] 2. By using an electric motor as the power source, combined with a transmission method involving gear meshing or friction connection, the automatic locking action becomes more reliable and precise, ensuring the timeliness and effectiveness of valve closure.

[0019] 3. The rechargeable battery pack design not only provides stable power support for the device but also reduces operating costs. Furthermore, the charging port and indicator lights facilitate user operation and help users understand the device's status.

[0020] 4. The one-button call function helps users quickly seek help in emergencies, further enhancing the device's emergency response capabilities. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1: The specific structure of this utility model is as follows:

[0029] Please refer to the appendix. Figure 1-4 The present invention discloses an intelligent control valve with an automatic locking mechanism to prevent air leakage, comprising a valve body 1, a clamping nut 6 connected to the upper end of the valve body 1, a valve stem 11 extending from the valve body 1 and the clamping nut 6 and controlling the opening and closing of the valve air passage by rotation, and a handwheel 2 installed at the outer end of the valve stem 11 and capable of controlling the rotation of the valve stem 11, wherein an annular cavity is formed between the handwheel 2 and the clamping nut 6.

[0030] The intelligent control valve also includes an automatic locking mechanism to prevent air leakage, which includes:

[0031] A component 4 that is fitted and fixed to the clamping nut 6 and is non-rotatable;

[0032] A power mechanism installed in the annular cavity and fixed to the handwheel 2 has a power source and a rotating component 5 driven by the power source. The rotating component 5 and the component 4 are connected by friction or meshing. The rotating component 5 moves around the component 4 due to the counter-thrust force generated by its self-rotation.

[0033] Preferably, the power source is a motor 10. When the rotating component 5 and the member 4 are meshed, the member 4 is a fixed gear and the rotating component 5 is a moving gear. The transmission between the moving gear and the fixed gear is stable.

[0034] Another transmission structure: a structure in which the rotating part 5 and the component 4 are connected by friction, that is, one of the rotating part 5 and the component 4 is a rubber disc, and the other is a metal disc or a plastic disc. The rotating part 5 rotates around the rubber disc by the friction between the rotating part 5 and the rubber disc.

[0035] A rechargeable battery pack 12 is also installed within the annular cavity; specifically, the battery pack 12 is an irregularly shaped battery pack. For example... Figure 4 As shown, the irregularly shaped battery pack has a C-shaped structure.

[0036] The battery pack 12 has a circuit board 9 mounted on its housing. The circuit board 9 is electrically connected to the battery pack 12. The circuit board 9 is also provided with a charging interface 8 and an indicator light 7. The charging interface 8 and the indicator light 7 are visible on the side of the handwheel 2.

[0037] like Figure 1 As shown, a sealing ring is provided between the valve stem 11 and the clamping nut 6. When the valve air passage is open and the sealing ring is loose, liquefied gas leaks from the gap of the sealing ring into the ring cavity.

[0038] The circuit board 9 also has a one-button call button 3, which is visible and operable on the side of the handwheel 2. Specifically, the circuit board 9 has a sensor for detecting liquefied petroleum gas (LPG). When LPG leaks into the annular cavity, the sensor detects the LPG, converts the detected signal into an electrical signal, and transmits it to the MCU on the circuit board 9. The MCU generates a control signal based on the electrical signal to control the motor to power on and operate.

[0039] like Figure 1 As shown, rotating handwheel 2 clockwise closes the valve, and rotating it counterclockwise opens the valve. Figure 2 As shown above, the air leakage indicates that handwheel 2 needs to be rotated clockwise to close the valve. Therefore, the motor drives the moving gear to rotate clockwise. Since the moving gear and the fixed gear are meshed and the fixed gear is stationary, the moving gear rotates clockwise around the fixed gear.

[0040] Since both the motor and the moving gear are fixed inside the handwheel 2, the clockwise rotation of the moving gear will drive the handwheel 2 to rotate clockwise as well. The handwheel 2 will close the valve, thus achieving the purpose of preventing air leakage.

[0041] In summary, this utility model incorporates an automatic locking mechanism that automatically triggers and closes the valve in the event of a liquefied gas leak, effectively preventing leakage and improving the safety of liquefied gas usage. The use of a motor as the power source, coupled with a gear meshing or friction connection transmission method, makes the automatic locking action more reliable and precise, ensuring the timeliness and effectiveness of valve closure. The rechargeable battery pack design not only provides stable power support for the device but also reduces operating costs. Furthermore, the charging interface and indicator lights facilitate user operation and monitoring of the device's status. The one-button call function allows users to quickly seek assistance in emergencies, further enhancing the device's emergency response capabilities.

Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
