Embodiment 1

[0031] Such as figure 1 , a pipeline with leakage suppression and dredging functions, including a multi-section pipeline 1 with shoulder rings 3 at both ends, and two adjacent pipeline sections 1 are fixedly connected by two flanges 2 to compress the shoulder ring 3; A sealing ring 4 is set on the periphery of the flange 2, and a closed chamber is formed between the gap between the two flanges 2 and the sealing ring 4, and an exhaust port 5 communicating with the closed chamber is also provided on the sealing ring 4 .

[0032] The sealing ring is a full circle formed by two half-rings connected by bolts, or it can be formed by connecting multiple arc-shaped rings, or even a complete ring, as long as a closed chamber can be formed for the leakage medium to overflow. In addition, in some special occasions, if the pipe is square or heterogeneous, the solution of the present invention is also applicable, and it can be used only by adjusting the shape of the sealing ring to match ...

Embodiment 2

[0037] The present invention is also applicable to situations where drainage guidance or recovery of liquid media is required. Such as Figure 4 , a pipeline and leakage collection system with leak suppression and dredging functions, a multi-section pipeline 1 with shoulder rings 3 at both ends, two adjacent sections of pipeline 1 are fixed by two flanges 2 to compress the shoulder ring 3 connection; the periphery of the flange 2 is also provided with a sealing ring 4, and a closed chamber is formed between the gap between the two flanges 2 and the sealing ring 4, and the bottom of the sealing ring 4 is also provided with a drain port 7; The liquid discharge port 7 is connected with a liquid recovery device 8 through a pipeline.

[0038] Same as Example 1, the sealing structure is a full circle formed by two semi-circular rings connected by bolts, or it can be formed by connecting multiple arc-shaped rings, or even a complete circular ring, as long as a closed chamber can be ...

Embodiment 3

[0041] Such as Figure 5, for some low-temperature medium transportation leakage, when there are gas injection conditions at the use site, the effect of leakage suppression can be promoted by injecting gas into the closed chamber of Example 1. Two gas injection ports 6 are set in the lower part of the sealed structure, and air or nitrogen is selectively fed in according to the site conditions, and the principle of rapid gasification of low-temperature medium under the action of gas is used to take away the heat flow and homogenize the local uneven cooling parts . The number of gas injection ports can also be one or more, which can be changed according to the requirements of use. In this embodiment, two are used as an example to consider that if the number is too large, multiple gas sources need to be connected, which is inconvenient to operate. Or the design still needs to be set up according to the conditions and requirements of the site. The specific position of the gas in...

Abstract

The invention relates to a pipeline with leakage suppression and dredging functions and a leakage collection system, and belongs to the field of pipeline conveying. The pipeline comprises multiple segments of pipelines, and shoulder circles are arranged at the two ends of each segment of pipeline. Every two segments of adjacent pipelines are fixed and connected by two flanges pressing down the shoulder circles. A sealing ring is arranged at the periphery of the flanges in a sleeved mode, a closed chamber is formed between the gap of the two flanges and the sealing ring, and an exhaust port communicating with the closed chamber is formed in the sealing ring. A drain outlet can also be formed in the bottom of the sealing ring and is connected with a liquid recovery device through a pipeline.A special medium or a general medium can be suppressed, collected and dredged by the pipeline, and the fluid properties of the medium are not limited. The invention provides the pipeline which can beused comprehensively. Especially in some special fields, such as rocket propellant precooling, the leakage time of precooling of a cryogenic pipeline is greatly shortened, and the effect is more obvious for the pipeline with a large diameter.

Description

technical field [0001] The invention belongs to the technical field of pipeline transportation, in particular to a pipeline and leakage collection system with functions of leakage suppression and dredging. Background technique [0002] Pipeline leakage is a common problem in the field of medium transportation. The general causes may include: insufficient sealing, stress deformation of pipeline connections caused by medium, and improper connection of pipeline joints. For various leakage problems, some can be suppressed, some cannot be suppressed or prevented, the medium needs to be guided, and even some dangerous fluids need to be collected and recycled. Most of the existing solutions are to prevent leakage by strengthening the sealing at the flange. However, in many cases, even if the sealing has been strengthened, there is still a risk of leakage. Once a leakage occurs, it can only be allowed to develop without further treatment. [0003] Pipeline transportation has a wid...
