Embodiment 1

[0033] In this embodiment, the leakage point 15 is located in the straight section of the pressurized pipeline 11 .

[0034] The leak plugging device under pressure for high-pressure pipelines comprises two pressure-bearing shells 1, and the two pressure-bearing shells 1 cover the leakage point 15 of the pressure-bearing pipeline 11. The pressure-bearing shells 1 are composed of pressure-bearing sections and The pressure-bearing section of each pressure-bearing shell 1 is composed of two limiting plates 3, and the limiting plates 3 on the two pressure-bearing shells 1 are connected in a corresponding sealing manner and sealed with the pressure pipeline 11. The limit plates 3 correspondingly arranged on the two pressure housings 1 form two sets of limit plates 3, and the two sets of limit plates 3 divide the pressure-bearing section into three injection chambers: the sealing chamber A16, the sealing chamber B17, and the pressure chamber 18. In the glue space, the leakage point ...

Embodiment 2

[0052] The difference between this embodiment and Embodiment 1 is that the leakage point 15 is located at the elbow of the pressurized pipeline 11 .

[0053] The leak plugging device under pressure for high-pressure pipelines comprises two pressure-bearing shells 1, and the two pressure-bearing shells 1 cover the leakage point 15 of the pressure-bearing pipeline 11. The pressure-bearing shells 1 are composed of pressure-bearing sections and Fixed segment composition. The fixed sections on both sides of the pressure-bearing section are perpendicular to each other, and the top wires 4 in the two fixed sections are perpendicular to each other.

[0054]When installing the limit plate 3 on both sides of the leakage point 15, the position and connection relationship of the two limit plates 3 need to be considered, and the space surrounded by the pressure housing 1 should be divided into a sealed cavity A16 by the limit plate 3 , sealing chamber B17, pressure chamber 18 three glue i...

Abstract

The invention relates to the high-pressure pipeline under-pressure leaking stoppage technology, in particular to a high-pressure pipeline under-pressure leaking stoppage device and method. The high-pressure pipeline under-pressure leaking stoppage device comprises two pressure-bearing housings. The two pressure-bearing housings wrap leakage points of a pipeline under pressure. Two limiting platesare arranged in a pressure-bearing section of each pressure-bearing housing and divide the pressure-bearing section into three sealant injection spaces, that is, a sealing cavity A, a sealing cavity Band a pressure-bearing cavity; a jackscrew is arranged on the pressure pipeline in a sleeving mode and inserted into a fixing section; the end of the jackscrew abuts against the limiting plates and is sealed to the limiting plates; and sealant is injected into the sealant injection spaces. Sealant is injected into the three sealant injection spaces in each pressure-bearing housing, so that it canbe effectively guaranteed that the sealant is completely filled, the leaking stoppage effect is obvious, meanwhile, the sealant injection efficiency can be improved, and leaking stoppage can be conveniently, rapidly and effectively conducted.

Description

technical field [0001] The invention relates to a high-pressure pipeline plugging technology under pressure, in particular to a high-pressure pipeline plugging device and method. Background technique [0002] The pressure plugging technology is widely used in chemical production, pipeline transportation and other fields, avoiding the discharge of materials in the car ordering operation, and has huge economic benefits. In the chemical industry, various types of pipelines and tanks are corroded, perforated, leaked, leaked, leaked, and leaked. Usually, plugging with pressure requires the production and installation of clamps, and then injects special sealant with pressure into the clamps through special glue injection tools. tool, forming a dense filling and forming a new seal. However, the existing leak-stopping method and leak-stopping device are prone to secondary dripping, poor sealing and the like. Contents of the invention [0003] The purpose of the present invention...
