Description

Technical Field

[0001] This utility model relates to the field of gas shut-off valve technology, specifically a household piped gas safety shut-off valve. Background Technology

[0002] Gas shut-off valves are a common type of safety shut-off valve installed on gas pipelines in residential homes. They are safety devices that automatically shut off when there is overpressure, underpressure, or overcurrent. They are mainly used for the connection and installation of municipal gas pipelines and household gas pipelines. Household gas pipelines are mainly divided into two types: metal corrugated pipes and rubber hoses. Different connectors are required when installing and fixing metal corrugated pipes and rubber hoses.

[0003] Existing household gas pipelines are mainly divided into two types: metal corrugated pipes and rubber hoses. Therefore, existing gas shut-off valves are mainly used with two different types of connectors depending on the type of gas pipeline. As a result, when installing and fixing existing gas shut-off valves in household gas pipelines, they can only be installed and fixed for the matched household gas pipeline, which reduces their flexibility and adaptability, making them somewhat inconvenient to use. During use and installation, if the purchased gas pipeline specifications are different, the existing gas shut-off valve may not be able to be installed in a sealing manner, which will also reduce the convenience of subsequent maintenance.

[0004] Therefore, this utility model provides a household piped gas safety shut-off valve to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown, this utility model provides a household gas pipeline safety shut-off valve, including a pipe body 1, with a first connector 11 at one end and a second connector 12 at the other end; a self-closing valve body 2, integrally disposed between the pipe bodies 1, and used for self-closing control of the pipe body 1; and a connector assembly 4, including a hexagonal nut 41, with a first threaded post 42 fixedly connected to one end of the hexagonal nut 41, and a first connector 43 integrally formed at the other end of the first threaded post 42, and a second threaded post 44 fixedly connected to the other end of the hexagonal nut 41, and a second connector 45 integrally formed at the other end of the second threaded post 44. Through the design of the connector assembly 4, the device can switch between the first connector 43 and the second connector 45 during actual use, thereby enabling the device to effectively adapt to different models of household gas pipelines for installation and fixation, thus improving the adaptability and flexibility of the device.

[0019] Furthermore, a rotating cylinder is integrally formed on the upper part of the pipe body 1, and a first flange 13 is fixedly connected to the top of the rotating cylinder. A valve shaft 14 is rotatably installed inside the rotating cylinder, and a ball valve 15 is fixedly connected to the bottom of the valve shaft 14. A servo motor 3 is connected above the first flange 13, and a drive shaft 32 is fixedly connected to the output end of the servo motor 3. The drive shaft 32 is inserted above the valve shaft 14. Through the installation of the servo motor 3, the valve shaft 14 and the ball valve 15 can be remotely rotated and driven, thereby enabling the device to achieve autonomous cut-off control of the pipe body 1 in actual use, further improving its safety.

[0020] Furthermore, the bottom of the servo motor 3 is fixedly connected to a second flange 31, and bolt fasteners pass through the corner of the second flange 31 and the first flange 13. The top of the valve shaft 14 has a rectangular structure. Through the setting of the rectangular structure at the top of the valve shaft 14, the valve shaft 14 and the drive shaft 32 can provide a certain torque when they are plugged together, so that the drive shaft 32 can drive the valve shaft 14 to rotate.

[0021] Furthermore, the first threaded post 42 and the second threaded post 44 have the same diameter, and both the first threaded post 42 and the second threaded post 44 can be threadedly connected to the second connector 12. A sealing gasket is provided on the outside of the first threaded post 42 or the second threaded post 44. The first threaded post 42 and the second threaded post 44 have the same length. By setting the sealing gasket, the sealing performance of the connection between the connector assembly 4 and the second connector 12 is improved, and the occurrence of gas leakage is reduced. The sealing gasket can be placed on the outside of the end connected to the second connector 12.

[0022] Furthermore, the first connector 43 and the second connector 45 are of the same length, and the outer diameters of the first connector 43 and the second connector 45 are both smaller than the diameter of the first threaded post 42. The first connector 43 is used for the installation and fixing of the metal bellows, and the second connector 45 is used for the installation and fixing of the rubber hose. The inner wall of the second connector 12 is provided with an internal thread that is adapted to the first threaded post 42 and the second threaded post 44, and the length of the second connector 12 is equal to the sum of the lengths of the first threaded post 42 and the first connector 43, so that when the connector assembly 4 is installed, its end can abut against the end of the pipe body 1, further improving its sealing performance.

[0023] Working principle: When the household gas pipeline is a metal corrugated pipe, during installation, the second threaded post 44 is connected to the second connector 12, and then the device can be installed with the metal corrugated pipe through the first connector 43. Conversely, when the gas pipeline is a rubber hose, the first threaded post 42 is connected to the second connector 12, and then the rubber hose can be fitted through the external second connector 45. With the help of external clamps, a tight seal can be achieved. Thus, the device can effectively adapt to different models of household gas pipelines for installation and fixation during actual use.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
