Online repair system and repair method after sealing failure of pipeline assembly

Abstract

The invention discloses an online repair system and repair method after sealing failure of a pipeline assembly. Each junction of a plurality of high-pressure pipelines connected end to end through connection assemblies to form a material conveying pipeline is sealed through a bag-type sealing diaphragm; the connection assemblies are located in the bag-type sealing diaphragms; an upper guide-out pipe is integrally formed on the upper part of each bag-type sealing diaphragm; a lower guide-out pipe is integrally formed on the lower part of each bag-type sealing diaphragm; an upper collection pipeis connected to a guide-out port of each upper guide-out pipe through an upper check valve; a lower collection pipe is connected to an output port of each lower guide-out pipe through a lower check valve; output ports of the upper collection pipe and the lower collection pipe are connected to a leaked material collection device separately; an output end of the leaked material collection device isconnected with the high-pressure pipeline which is nearest to the output end of the leaked material collection device through material pressing equipment; and the collected leaked materials are conveyed back into the high-pressure pipeline. The online repair system and repair method after sealing failure of the pipeline assembly does not need to stop, and is capable of repairing in the case of atemperature and a pressure, and the repair effect achieves zero leakage.

Description

technical field [0001] The invention relates to the sealing of a high-pressure pipeline and a high-pressure pipeline connection assembly. In particular, it relates to an online repair system and repair method after the seal failure of pipeline components. Background technique [0002] Most of the materials conveyed in the pipelines of refineries and chemical plants have such characteristics: gas-liquid miscibility, high temperature, high pressure, flammable, explosive, toxic, strong corrosion, etc. The overall delivery pipeline is composed of numerous pipelines connected end to end, and the pipelines are connected by connecting components, so the number of connecting components on the entire pipeline is quite large, and the structure and size of the connecting components are also different. According to different positions, different connection components are used. Such as Figure 1 to Figure 4 As shown, there are different connection components such as manual valve connec...
