Embodiment Construction

[0042] In order to better understand the present application, the technical solutions in the present application embodiment will be described in conjunction with the drawings in the present application. Obviously, the embodiments described below are only part of the present application embodiment, not all. Based on the embodiments described in the present application, those skilled in the art without paying creative labor, all of the present application protected within the scope of the present application.

[0043] In the study, it was found that the current nuclear power plant temporary pipe sealing fixture is generally two semi-circular hugs plus sealing rubber, using sealing rubber contacts, two clamps are connected to bolts on both sides. . Since there is a tension in both sides, the strip produces a shape under the effect of the clamp friction, resulting in a small tape in the bolt, the leak is pulled, and the strip has become weak and sensitive. Since the surface of the rub...

Abstract

The invention belongs to the technical field of nuclear power station pipeline maintenance, and particularly relates to a device for nuclear power station pipeline crevasse sealing and strength protection. By changing a force application mode of a clamp, a plane structure of a sealing rubber strip and a butt joint interface mode, the stress condition of the sealing rubber strip is improved, the weak sensitive area of the rubber strip is eliminated, the sealing structure is optimized, the sealing performance is enhanced, and the amount of a pipeline medium sprayed to the periphery when the clamp is installed is reduced. Moreover, by installing a strength protection mechanism, the pipeline fracture risk is reduced.

Description

Technical field [0001] The present application belongs to the field of nuclear power plant pipe maintenance technology, and is specifically related to means for nuclear power plant pipeline breaking sealing and strength protection. Background technique [0002] Nuclear power plant pipelines, most of which are vapor, acid-base, seawater, etc. Waiting for many broken problems, pipeline striking management is an important part of nuclear power plant maintenance activities. [0003] It is currently divided into welding treatment and temporary sealing treatment for pipeline governance. Welding mode is divided into pipelines, divided into soldering and cutting, and its sealing effect is intuitive and reliable, and has been favored by engineers and technicians. However, welding techniques are also limited, and the water-containing water welding cannot achieve the ideal effect, the welding strength and weld quality are very poor; the PT or RT verification of weld welds after welding achi...
