Abstract
A metal corrugated pipe crack plugging device comprises a left half shell and a right half shell, wherein the left half shell and the right half shell are locked up and down through locking bolts; the corrugated rubber sealing gasket is provided with a convex hull, and the water-curing plugging agent is placed in the convex hull. The utility model provides a pair of corrugated metal pipe crackle plugging device can the quick leaking stoppage.
Description
Technical Field
The utility model relates to a bellows, especially a corrugated metal pipe crackle plugging device.
Background
The metal corrugated pipe material for flat pressing of a unit in a certain power station belongs to 304 stainless steel, when the metal corrugated pipe is installed, the metal corrugated pipe is not concentric to generate distortion deformation, after the metal corrugated pipe is operated for a long time to reach certain fatigue strength, the metal corrugated pipe is broken, and the metal corrugated pipe cannot be stopped and replaced during full-load power generation of the unit in a flood season.
Disclosure of Invention
The utility model aims to solve the technical problem that a corrugated metal pipe crackle plugging device is provided, can be fast to the pipeline locking leaking stoppage, from guaranteeing unit safety and stability operation.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
a metal corrugated pipe crack plugging device comprises a left half shell and a right half shell, wherein the left half shell and the right half shell are locked up and down through locking bolts; the corrugated rubber sealing gasket is provided with a convex hull, and the water-curing plugging agent is placed in the convex hull.
The left half shell and the right half shell are made of high-strength high-quality carbon tool steel.
The convex hull is pocket type structure, and the upper end is equipped with the opening, and the convex hull lateral wall is equipped with the hole of permeating water.
The utility model relates to a corrugated metal pipe crackle plugging device has following technological effect: the corrugated rubber sealing gasket can be quickly sealed with the metal corrugated pipe, and the water-curing plugging agent filled in the corrugated rubber sealing gasket can play a role in secondary sealing, so that quick plugging is realized. The two high-strength high-quality carbon tool steels are divided into half shells, so that the use is convenient, the time and the labor are saved, the defects can be eliminated most efficiently, and the leakage points can be treated.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
Fig. 3 is a schematic view of the present invention.
Fig. 4 is a schematic view showing a state where a crack is generated in the metal bellows.
In the figure: the device comprises a left half shell 1, a right half shell 2, a locking bolt 3, a corrugated rubber sealing gasket 4, a metal corrugated pipe 5, a convex hull 6, a water-curing plugging agent 7, cracks 8, a fixing bolt 9 and a corrugated pipe flange 10.
Detailed Description
As shown in fig. 1-3, a metal corrugated pipe crack plugging device comprises a left half shell 1 and a right half shell 2, wherein the left half shell 1 and the right half shell 2 are made of high-strength high-quality carbon tool steel. The upper and lower parts of the left half shell 1 and the right half shell 2 are respectively fixed with an ear plate, and the locking bolt 3 passes through the ear plates and then is fixed through a nut. Flanges are arranged on the left side and the right side of the left half shell 1 and the right half shell 2, and the corrugated rubber gaskets 4 are arranged in the left half shell 1 and the right half shell 2 and are positioned through the flanges to prevent the displacement. The corrugated rubber gasket 4 is matched with the corresponding metal corrugated pipe 5, and after the corrugated rubber gasket 4 and the metal corrugated pipe 5 are installed, the corrugated rubber gasket 4 is tightly attached to realize initial sealing.
The corrugated rubber sealing gasket 4 is provided with a convex hull 6 at a proper position, the convex hull 6 is of a pocket type structure and is internally provided with a containing cavity, and the upper end of the convex hull 6 is provided with an opening for placing an inlet of a water-curing plugging agent 7. The 6 lateral walls of convex closure are equipped with the hole of permeating water, and when convex closure 6 is just right to 8 departments of crackle, water gets into in the convex closure 6 and meets with water curing plugging agent 7 through the hole of permeating water and takes place the solidification of chemical reaction postcure to realize secondary seal. The water-curable plugging agent 7 adopts a product in a patent with application number of 201610511520.8, namely a fast-curing water-resistant plugging material and a preparation method and an application method thereof.
The working principle and the process are as follows: when the metal corrugated pipe 5 is broken, the plugging device matched with the pipe diameter is selected according to the pipe diameter of the metal corrugated pipe 5, the locking bolt 3 is firstly loosened, the corrugated rubber sealing gasket 4 is opened, the device is wrapped on the corrugated pipe, the convex hull 6 in the device is aligned to the crack, the water-curing plugging agent 7 is rapidly placed into the convex hull 6, the convex hull 6 is wrapped at the crack 8, the left half shell 1 and the right half shell 2 are locked through the locking bolt 3, the corrugated rubber sealing gasket is tightly pressed on the metal corrugated pipe 5, and no water seepage exists in the corrugated pipe gap.
