Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure pipeline plugging, and particularly relates to a plugging device for high-pressure pipelines. Background Technique

[0002] In the general assembly and general test area, the gas power system plays a crucial role, including high-pressure air supply systems, high-pressure nitrogen supply systems, high-pressure helium supply systems, and process equipment control systems. These systems jointly provide air, nitrogen, and helium media that meet specific requirements for the rocket assembly workshop (covering the general assembly transfer area and vertical test area), component manufacturing and turnover workshops, and the second-phase garage. Especially for the high-pressure air supply system, in order to maximize the gas storage capacity in the limited space of the tank area, the high-pressure air storage tanks are uniformly selected according to the 45MPa grade and generally adopt a vertical structure. When emergencies such as leaks and perforations occur in the above high-pressure pipelines, the high-pressure non-stop transmission plugging technology can quickly plug the leakage points.

[0003] However, there are at least the following two problems in the current plugging devices for high-pressure pipelines during use:

[0004] 1. It is not easy to adjust the use height, resulting in difficulty in effectively plugging high-pressure pipelines at different heights;

[0005] 2. The sealing effect is poor, which directly affects the plugging effect of high-pressure pipelines. Therefore, we urgently need to introduce a new plugging device for high-pressure pipelines to solve the above problems. Content of the Utility Model

[0006] The main purpose of the utility model is to provide a plugging device for high-pressure pipelines, which can effectively solve the problems in the background technique.

Connecting screws are respectively inserted through the upper right end and the lower right end of the connecting ring. A rubber sleeve is fixedly connected to the right end of the sealing pipe in a penetrating manner. The sealing pipe is inserted through the plugging frame.

[0013] By adopting the above technical solution: The rubber sleeve is sleeved on the pipeline to be plugged, and the sealing pipe is inserted through the plugging frame, which can strengthen the sealing effect during the connection between the sealing assembly and the plugging frame.

[0014] Preferably, the two limiting screws respectively pass through the fixing plate and are inserted through the two connecting plates.

[0015] By adopting the above technical solution: The positions of the two can be positioned through the two limiting screws to fix the using position of the plugging assembly.

[0016] Preferably, the two connecting screws respectively pass through the connecting ring and are inserted through the plugging frame.

[0017] By adopting the above technical solution: The two connecting screws can fix the connection between the sealing assembly and the plugging frame.

[0019] By adopting the above technical solution: The connection between the sealing assembly and the plugging frame can be strengthened through the anti-slip layer.

[0021] 1. By setting two support rods and two extension rods, the connection length between the two support rods and the two extension rods can be adjusted synchronously and fixed respectively by screws, so that the use height of the fixed plate can be adjusted, enabling the plugging assembly to plug high-pressure pipelines at different heights and improving flexibility.
