Description
Technical Field
The utility model relates to a bellows, especially an emergent plugging device of narrow and small space corrugated metal pipe crackle.
Background
The metal corrugated pipe material for flat pressing of the unit to a dam 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, the metal corrugated pipe cannot be stopped and replaced during full-load power generation of the unit in a flood season, and the unit needs to continue to operate stably. The metal corrugated pipe is installed at a narrow position, so that other large-scale equipment is inconvenient to plug, and the currently used small-sized pipeline plugging device is mostly used on a round pipeline and is not suitable for plugging on the metal corrugated pipe.
Disclosure of Invention
The utility model aims to solve the technical problem that an emergent plugging device of narrow and small space corrugated metal pipe crackle is provided, the corrugated metal pipe shutoff leak-stopping in being applicable to narrow and small space guarantees the safety and stability operation flood season of unit.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
the utility model provides an emergent plugging device of narrow and small space metal bellows crackle, includes the inside lining, and the inside lining cladding is equipped with the outlet at bellows outside and the lower extreme, is equipped with half cylinder closure plate, lower half cylinder closure plate outside the inside lining, sealing connection between first cylinder closure plate, the lower half cylinder closure plate, sealing connection between first cylinder closure plate, lower half cylinder closure plate and the bellows, and the drum bottom that first cylinder closure plate, lower half cylinder closure plate formed is equipped with the drain pipe, and the drain pipe is nested with the outlet.
The upper half cylinder plugging plate and the lower half cylinder plugging plate are fixedly connected with each other in a welding mode, and the upper half cylinder plugging plate and the lower half cylinder plugging plate are fixedly connected with the corrugated pipe in a welding mode.
The drain pipe is provided with a drain valve.
The lining is made of an iron sheet, and the thickness of the iron sheet is 0.5mm-1.5 mm.
The utility model relates to an emergent plugging device of narrow and small space corrugated metal pipe crackle has following technological effect: through upper and lower two blocks of half-cylinder closure plates, can be very suitable give whole totally closed with former corrugated metal pipe, guarantee that breaking of former corrugated metal pipe does not influence the normal operating of equipment, the installation of bottom drain valve can guarantee that equipment fixing welds in the time there is not ponding in the drum, guarantees welded quality, the use of sheet iron can guarantee that leaking of bellows does not influence the welding, and the sheet iron can be buckled wantonly moreover, prevents when the manger plate that the welding slag from splashing and causes the equipment to damage. The emergency plugging device is simple and convenient to manufacture, materials can be formed by welding a large-size carbon steel pipe and an iron plate, time and labor are saved, the defect can be eliminated, and the leakage point can be treated.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a front view of the present invention after installation.
Fig. 2 is a left side view of the utility model after installation.
Fig. 3 is a front view of the present invention.
Fig. 4 is a left side view of the present invention.
In the figure: the water-saving device comprises a bolt 1, a flange 2, a corrugated pipe rupture leak point 3, a welding position 4, an upper semi-cylinder plugging plate 5, a lining 6, a lower semi-cylinder plugging plate 7, a drain valve 8, a drain pipe 9, a corrugated pipe 10 and a drain outlet 11.
Detailed Description
As shown in fig. 1-4, the emergency leak stopping device for cracks of a metal corrugated pipe in a narrow space comprises a lining 6, wherein the lining 6 is made of a sheet iron, a water outlet 11 is formed in the middle of the sheet iron, the sheet iron is wrapped outside the corrugated pipe 10 after being wound to form the lining 6, and the water outlet 11 faces downwards.
An upper semi-cylinder blocking plate 5 and a lower semi-cylinder blocking plate 7 are arranged outside the lining 6, the upper semi-cylinder blocking plate 5 and the lower semi-cylinder blocking plate 7 are welded, the two ends of the upper semi-cylinder blocking plate 5 and the lower semi-cylinder blocking plate 7 are welded with the corrugated pipe 10, and the formed cylinder and the corrugated pipe 10 keep a sealing connection relation to achieve the purpose of water blocking.
A drain pipe 9 is arranged at a proper position on the outer wall of the lower semi-cylindrical plugging plate 7, and a drain valve 8 is arranged on the drain pipe 9. The drain pipe 9 is nested with the drain port 11. Is used for draining water when the upper semi-cylinder blocking plate 5 and the lower semi-cylinder blocking plate 7 are welded.
The working principle and the process are as follows: when the corrugated pipe 10 is found to be broken, a leakage stopping device with corresponding size is manufactured according to the pipe diameter of the corrugated pipe 10. When the corrugated pipe is installed, the outer surface of the corrugated metal pipe is firstly wrapped by a sheet iron to form an inner lining 6, and a water outlet 11 is reserved in the middle of the sheet iron and communicated with a water outlet pipe 9. And then welding the upper half cylinder plugging plate 5, the lower half cylinder plugging plate 7 with the water discharge pipe 9 and the water discharge valve 8 on the metal corrugated pipe, and closing the water discharge valve 8 after all welding is finished.
