The petroleum pipeline breach sealing structure of claim, wherein said sealing assembly comprises a fixing frame, said fixing frame is annular and is disposed around the outside of the pipeline, said fixing frame is provided with an inflation inlet, and an annular sealing air bag is disposed inside the fixing frame.
The split petroleum pipeline plugging structure of claim, wherein the flexible sleeve is fixedly attached to a flange, and the flange is attached to the side of the plugging member by screws.
The petroleum pipeline breach sealing structure of claim, wherein said mounting bracket is divided into two portions, and is fixedly connected by a connecting portion.
The petroleum pipeline breach sealing structure of claim, wherein said sealing components are connected and fixed by a fixing component, and said sealing components are connected by a connecting rod, and said connecting rods are connected by a connecting component.
The petroleum pipeline breach sealing structure of claim, wherein a sensor is disposed at the inflation port of the fixing frame, and a pressure gauge is disposed outside the fixing frame for indicating the pressure inside the sealing air bag.
The petroleum pipeline breach sealing structure of claim, wherein said sealing bladder is inflated by an externally connected gas canister.
Compared with the prior art, the invention has the beneficial effects that:
by arranging the plugging air bag, the invention can be quickly adapted to various petroleum pipelines, and the storage of different plugging devices is reduced.
According to the invention, by arranging the flexible sleeve, a proper plugging length can be selected more conveniently according to the actual situation of the crack, so that the plugging range is determined.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this embodiment: referring to fig. 1 and fig. 2, the present invention provides a technical solution: the utility model provides a petroleum pipeline breach block structure, its includes shutoff subassembly 2, flexible sleeve 3 and fixed subassembly 4, its characterized in that, two 2 covers of shutoff subassembly are established at 11 both sides of breach of pipeline 1, and flexible sleeve 3 is connected between two shutoff subassemblies 2.
The plugging component 2 comprises a fixing frame 21, the fixing frame 21 is annular and is sleeved on the outer side of the pipeline 1, an inflating port 23 is arranged on the fixing frame 21, an annular plugging air bag 22 is arranged inside the fixing frame 21, the fixing frame 21 is divided into two parts which are fixedly connected through a connecting part 27, the plugging air bag 22 is inflated through an external air tank 24, and the plugging air bag can be better matched with the curved surface on the outer side of the pipeline, so that sealing is realized.
The flexible sleeve 3 is fixedly connected to a flange plate 31, the flange plate 31 is connected to the side face of the plugging assembly 2 through a screw 32, and the length of the flexible sleeve is determined through the position of a pipeline crack, so that the coverage range of the plugging device is determined.
The plugging components 2 are fixedly connected through the fixing component 4, the plugging components 2 are connected with the connecting rods 41, the two connecting rods 41 are connected through the connecting piece 42, and the two plugging components can be more stably fixed through the connecting rods, so that the plugging components cannot deviate during working.
A sensor 25 is arranged at the inflation port 23 of the fixing frame 21, a pressure gauge 26 for indicating the air pressure in the plugging air bag 22 is arranged outside the fixing frame 21, the air pressure in the plugging air bag is sensed by the sensor when the air tank is inflated, and the pressure gauge determines the pressure between the plugging component and the pipeline.
When concrete implementation, prevent that the pipeline outside from having the installation that the arch influences the shutoff subassembly, the staff will appear the petroleum pipeline outside clean up of breach earlier, then arrange the shutoff gasbag in the mount, and connect the gas port of shutoff gasbag in the inflation inlet on the mount, then install the mount two parts in the pipeline outside, and inflate the shutoff gasbag through the gas pitcher, when the gasbag internal pressure reached suitable pressure, stop inflating, then couple together two shutoff subassemblies of pipeline breach both sides through connecting rod and connecting piece, thereby prevent that the shutoff subassembly from taking place the skew at the during operation.
