Description

Technical Field

[0001] The utility model relates to the field of gas transportation pipelines, and more specifically, it relates to a gas transportation pipeline with anti-leakage function. Background Art

[0002] Pipelines are very common in industrial production. Since gases are inconvenient to transport by means of vehicles such as cars, various liquids and gases used in industrial production are generally transported to factories through pipelines. When using pipelines to transport gases, it is often necessary to prevent gas leakage. Existing gas transportation pipelines generally lack anti-leakage structures. Pipes are connected to each other through flanges and bolts, and gases are likely to leak at the splicing positions of the pipelines, resulting in gas loss. At the same time, during the daily use of pipelines, they are easily affected by the external environment and are prone to damage. Existing pipelines lack protective structures. When the pipelines are impacted by the external environment, the damage to the pipelines will cause a large amount of gas leakage, thus affecting the gas transportation by the pipelines.

[0015] (III) Advantageous Effects

[0016] Compared with the prior art, the present utility model provides a gas transportation pipeline with anti-leakage, and has the following advantageous effects:

[0017] 1. The utility model sets a sealing ring detachably arranged on the connecting disc of the outer layer pipeline. When connecting two transportation pipelines, the connecting discs of the two outer layer pipelines are connected through the cooperation between the second sealing groove arranged on the connecting disc of one outer layer pipeline and the second sealing block opened on the connecting disc of the other outer layer pipeline. The sealing ring is sleeved and installed on the outer sides of the connecting discs of the two outer layer pipelines. Through the cooperation between the first sealing block arranged on the cooperation ring and the first sealing groove opened on the outer wall of the outer layer pipeline, the joint position of the two connecting discs is sealed by the sealing ring. The sealing ring is installed on the outer sides of the two outer layer pipelines, thereby sealing the pipeline joint position, reducing gas leakage, and facilitating the transportation of gas in the pipeline.

[0018] 2. The utility model sets a protection structure at the upper end of the outer layer pipeline. Through the cooperation between the installation hole and the installation post, the first protection plate, the second protection plate and the spring are all installed on the installation post. Through the threaded cooperation between the limiting piece and the installation post, the first protection plate and the second protection plate are installed between the two installation rings, thus completing the installation of the protection structure. When the pipeline is impacted by the outside world, the second protection plate compresses the spring to resist part of the impact, thereby protecting the entire pipeline through the first protection plate and the second protection plate.

[0019] 3. The utility model sets an outer layer pipeline and an inner layer pipeline to jointly form a transportation pipeline structure. When transporting gas normally, the gas passes through the inside of the inner layer pipeline. When the side wall of the inner layer pipeline is damaged, part of the gas in the inner layer pipeline escapes into the flow channel between the outer layer pipeline and the inner layer pipeline and continues to be transported. Therefore, compared with a single-layer pipeline, the gas will not overflow from the pipeline after leakage, thus reducing gas loss. Description of the Drawings
