Description

Technical Field

[0001] The utility model relates to the technical field of pipeline interfaces, and in particular to a multi-port connection assembly for a gas pipeline. Background Art

[0002] A gas pipe is a specialized pipeline used to transport combustible gas. It's made of metal, plastic, and other materials. Common household gas pipes are small-diameter metal pipes that are typically connected to a larger-diameter outdoor gas pipe.

[0003] Gas pipelines can be branched off as needed. A common approach involves first assessing the pipeline, closing the valves, treating and assessing the gas in the pipeline, and then cutting the pipeline open and connecting to a new pipeline. However, this approach is not only cumbersome but also results in a prolonged outage and significant disruption. Therefore, a more efficient device for adding branch pipes to gas mains is needed. Utility Model Content

[0004] The purpose of the utility model is to provide a gas pipeline multi-port connection assembly, which can conveniently and efficiently connect a new branch pipe to a gas main pipe.

[0005] The utility model is achieved through the following technical solutions: the utility model provides a multi-port gas pipeline connection assembly, comprising a main pipe, a connecting pipe, a pair of first valves respectively arranged at both ends of the connecting pipe, a plurality of side pipes arranged on the connecting pipe, and a plug arranged on one end of the side pipe away from the connecting pipe; the side pipe is used to connect a branch pipe; both ends of the connecting pipe are connected to the side wall of the main pipe.

[0006] Furthermore, the material of the plug is the same as that of the side tube.

[0007] Furthermore, the plug is welded to the end of the side pipe.

[0008] Furthermore, a second valve is provided on the side pipe connected to the branch pipe.

[0009] Furthermore, the connecting pipe is connected to an exhaust pipe, and the exhaust pipe is provided with a third valve.

[0010] The technical solution of the present invention has at least the following advantages and beneficial effects: the multi-port connection assembly of the gas pipeline of the present invention connects the connecting pipe to the main pipe when the main pipe is laid, and connects the branch pipe to the side pipe as needed. When a new branch pipe needs to be connected later, the valves at both ends of the main pipe can be cut off first, and after evaluation, the first valves at both ends of the connecting pipe can be closed, the valves on the connected branch pipes can be closed, and then the plug can be removed from the side pipe, and the new branch pipe can be connected to the side pipe. In this way, the installation of the new branch pipe is more convenient and efficient. Moreover, since the first valve completely cuts off the connecting pipe from the main pipe, it is also possible to choose not to cut off the main pipe and add a new branch pipe to the connecting pipe when the main pipe is supplying gas normally, so as not to affect the normal gas supply.

[0019] Example

[0020] The following is further described in conjunction with specific embodiments. Figure 1 As shown, the multi-port gas pipeline connection assembly of this embodiment includes a main pipe 1, a connecting pipe 2, a pair of first valves 3 respectively provided at both ends of the connecting pipe 2, multiple side pipes 4 provided on the connecting pipe 2, and a plug 5 provided at one end of the side pipe 4 away from the connecting pipe 2; the side pipe 4 is used to connect to the branch pipe 7; both ends of the connecting pipe 2 are connected to the side wall of the main pipe 1. Specifically, when the main pipe 1 is laid, the connecting pipe 2 is connected to the main pipe 1, and the branch pipe 7 is connected to the side pipe 4 as needed. When a new branch pipe 7 needs to be connected later, the valves at both ends of the main pipe 1 can be disconnected and evaluated. Then, the first valves 3 at both ends of the connecting pipe 2 and the valves on the already connected branch pipe 7 can be closed. The plug 5 can then be removed from the side pipe 4 and the new branch pipe 7 can be connected to the side pipe 4. This makes the installation of the new branch pipe 7 more convenient and efficient. Moreover, since the first valve 3 completely disconnects the connecting pipe 2 from the main pipe 1, it is also possible to choose not to disconnect the main pipe 1 and add a new branch pipe 7 to the connecting pipe 2 while the main pipe 1 is supplying gas normally, thus not affecting the normal gas supply.

[0021] The plug 5 in this embodiment is made of the same material as the side tube 4. The plug 5 is welded to the end of the side tube 4. Specifically, this can better seal the side tube 4. When connecting the branch pipe 7, only part of the plug 5 needs to be cut off.

[0022] In this embodiment, the side pipe 4 connected with the branch pipe 7 is provided with a second valve 6. Specifically, when installing a new branch pipe 7, it is only necessary to close the first valve 3 and the second valve 6.

[0023] In this embodiment, the connecting pipe 2 is connected to an exhaust pipe 8, which is equipped with a third valve 9. Specifically, the exhaust pipe 8 is primarily used to discharge the gas in the connecting pipe 2 to facilitate the connection of the new branch pipe 7. To do this, the exhaust pipe 8 needs to be connected to a dedicated negative pressure device. Then, the third valve 9 is opened to partially extract the gas. Nitrogen is then injected into the connecting pipe 2 through the exhaust pipe 8, and the gas is then extracted. This process is repeated multiple times to dilute the gas to a level suitable for normal operation. This ensures better worker safety when connecting the branch pipe 7.

[0024] In summary, in the multi-port gas pipeline connection assembly of this embodiment, the connecting pipe 2 is connected to the main pipe 1 when the main pipe 1 is laid, and the branch pipe 7 is connected to the side pipe 4 as needed. When a new branch pipe 7 needs to be connected later, the valves at both ends of the main pipe 1 can be cut off first, and after evaluation, the first valves 3 at both ends of the connecting pipe 2 can be closed, the valves on the already connected branch pipe 7 can be closed, and then the plug 5 can be removed from the side pipe 4, and the new branch pipe 7 can be connected to the side pipe 4. This makes the installation of the new branch pipe 7 more convenient and efficient. Moreover, since the first valve 3 completely cuts off the connecting pipe 2 from the main pipe 1, it is also possible to choose not to cut off the main pipe 1 and add a new branch pipe 7 to the connecting pipe 2 when the main pipe 1 is supplying gas normally, so as not to affect the normal gas supply.

[0025] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
