Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline technology, and in particular relates to a pipeline purging connection structure. Background Technology

[0002] In the process of piped gas transportation, especially the main pipe for residential gas, it is usually made of metal and is generally installed vertically upwards, with its bottom connected to the gas inlet pipe. However, as the service life of the main pipe increases, rust and other impurities are prone to fall off, thus affecting the use of the pipeline. Current pipeline technology usually has a closed installation structure, and some are equipped with purge ports. However, the purge ports are usually in the direction of gas inlet, so when purging impurities, the gas and solid mixture cannot be separated. Therefore, how to purge and separate impurities in vertical pipelines has been a difficult problem that those skilled in the art have been thinking about. Utility Model Content

[0003] The purpose of this utility model is to provide a pipeline purging connection structure to solve the technical problem that impurities in gas pipelines cannot be separated and removed in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A pipeline purging connection structure includes: an air inlet and an air outlet, the upper part of the air inlet being connected to the middle part of the air outlet, the air outlet being installed vertically, the air outlet having a sedimentation section extending downwards, a removable purging plug being installed at the end of the sedimentation section, the end of the air inlet being connected to an air inlet pipe, the air outlet being connected to an air supply pipe, and the opening of the sedimentation section being arranged in a vertically downward direction.

[0006] The present invention provides a pipeline purging connection structure in which the upper end of the air outlet is bent to form a connection part, the connection part and the air outlet are connected in a transitional manner, and the connection part has an arc-shaped structure.

[0007] The present invention relates to a pipeline purging connection structure in which the main axes of the air inlet and air outlet are arranged in parallel.

[0008] This utility model discloses a pipeline purging connection structure, wherein the air outlet is connected to the air supply pipe through the air outlet interface, and the end of the air inlet is connected to the air inlet pipe through the air inlet interface. The air outlet interface is arranged vertically upward, and the air inlet interface is arranged vertically downward.

[0009] This utility model discloses a pipeline purging connection structure, wherein the air inlet is connected to the air inlet pipeline via an external thread or flange.

[0010] This utility model discloses a pipeline purging connection structure, wherein the air outlet is connected to the air supply pipeline via an external thread, an internal thread, or a flange.

[0011] In this utility model, a pipe purging connection structure is provided, wherein the bottom of the purging plug is higher than the bottom of the air inlet.

[0012] The present invention provides a pipeline purging connection structure, wherein the connecting part and the air outlet are connected by welding.

[0013] The beneficial effects of this utility model are as follows: It proposes a pipeline purging connection structure. By setting a sedimentation section at the bottom of the air outlet, impurities naturally settle in the sedimentation section under gravity when cleaning is required after purging, thus creating a space for accumulation and facilitating centralized cleaning. Furthermore, a purging plug is set in the sedimentation section, allowing for periodic purging and cleaning of impurities from this point. The arc-shaped connecting section connects the air inlet and outlet, reducing pipeline resistance and simplifying the connection structure, avoiding excessive joints. Additionally, the air outlet and inlet interfaces can be connected to the corresponding pipelines using threaded connections, making installation more convenient. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings:

[0017] like Figure 1 As shown, a pipeline purging connection structure includes: an air inlet 1 and an air outlet 2. The upper part of the air inlet 1 is connected to the middle part of the air outlet 2. The air outlet 2 is installed vertically and has a sedimentation part 4 extending downward. A detachable purging plug 5 is installed at the end of the sedimentation part 4. The end of the air inlet 1 is connected to an air inlet pipe, and the air outlet 2 is connected to an air supply pipe. The opening of the sedimentation part 4 is arranged in a vertically downward direction.

[0018] It should be noted that the air inlet pipe is usually set vertically. After the air outlet is converted, it is connected to the vertical section of the main inlet pipe. This solves the problem of cleaning the pipe from the ground floor to the top floor. The sedimentation section 4 has a certain length, such as 5 centimeters, which is enough to hold impurities without affecting normal use.

[0019] In a preferred embodiment of the present invention, the upper end of the air outlet 2 is bent to form a connecting part 3, and the connecting part 3 is transitionally connected to the air outlet 2. The connecting part 3 has an arc-shaped structure.

[0024] In a preferred embodiment of this utility model, the air outlet 6 is connected to the air supply pipe via an external thread, an internal thread, or a flange.

[0025] In a preferred embodiment of this utility model, the bottom of the purge plug 5 is higher than the bottom of the air inlet 7, which provides operating space for removing impurities.

[0026] In a preferred embodiment of this utility model, the connecting part 3 and the air outlet part 2 are connected by welding.
