The fixed band is the shape fibrous zone is returned to high strength, and the shape fibrous zone is returned to high strength is last to be equipped with a plurality of type holes of returning along length direction.
And one side of the sealing pressing plate, which is in contact with the water leakage point, is provided with a sealing gasket.
The sealing gasket is made of polytetrafluoroethylene.
The sealing pressure plate can be flat or arc.
The utility model relates to a quick leaking stoppage frock of low-pressure pipeline has following technological effect:
1) the support can be used for supporting and connecting all the parts to form a whole, and the fixing band can be used for tensioning the support and uniformly bearing the stress of the pipeline; the special bolt can be used for jacking the sealing pressure plate, and the sealing pressure plate is used for supporting and pressing the sealing gasket to prevent the tool from overturning and losing efficacy.
2) The tool can efficiently finish the low-pressure pipeline leakage stopping work of different fluids, different pipe diameters and different materials only by 1 person, and labor cost is saved.
3) The tool can rapidly eliminate the waste of fluid caused by pipeline corrosion, sand holes and cracks and the safety risk caused by fluid leakage, and has the advantages of simple structure, convenience in operation, wide application range, good leakage stopping effect, safety and reliability.

Detailed Description
As shown in fig. 1-9, a quick leaking stoppage tool for a low-pressure pipeline comprises a fixing band 3, wherein the fixing band 3 is a high-strength rectangular fiber band, and a plurality of rectangular holes 9 are formed in the high-strength rectangular fiber band along the length direction. The fixing belt 3 is sleeved on the water leakage pipeline 7, two ends of the fixing belt are hung on the hanging device of the support 2 through the return holes 9, and the fixing belt 3 keeps a tensioning state. The support 2 is in threaded connection with a bolt 1, the end of the bolt 1 is inserted into the sealing pressure plate 4, and the sealing pressure plate 4 is pressed against the water leakage point 8.
And a sealing gasket 5 is arranged on one side of the sealing pressing plate 4, which is in contact with the water leakage point 8. The sealing gasket 5 is made of polytetrafluoroethylene. The polytetrafluoroethylene gasket is made of softer material and has better sealing effect.
The sealing pressure plate 4 can be flat or arc. The structure of the sealing pressure plate 4 is ensured to be matched with the water leakage pipelines 7 with different pipe diameters. The present application contemplates, but is not limited to, three of the figures in the specification.
The bolt 1 is a special bolt, namely the part of the front section matched with the inner hole of the sealing pressure plate 4 is a cylinder, and the rear section is a threaded column.
The bolt 1, the bracket 2 and the sealing pressure plate 4 are made of carbon steel or stainless steel.
The working principle and the process are as follows:
before emergency plugging is carried out by using the low-pressure pipeline rapid plugging tool, 1 square polytetrafluoroethylene pad (with the thickness of 2mm and the area of more than 40mmX40 mm), 1 circle of double-sided adhesive tape, 1 pair of scissors, 1 pair of scraper and 1 bottle of lubricating oil are prepared.
1) The inspection tool is complete, and the confirmation tool is suitable for a water leakage point 8 (the water leakage point is concentrated in a circle range with the diameter of 10mm, and the outer diameter of the pipeline is not required to be smaller than 50 mm).
2) And selecting a proper sealing pressure plate 4 according to the diameter of the water leakage pipeline 7.
3) The surface of the pipe is cleaned by a scraper to remove the paint coat and the rust (plastic pipes and the like can omit the operation).
4) A40 mm X40mm Teflon pad was cut and attached to the sealing platen 4 with double sided adhesive.
5) Proper amount of lubricating oil is smeared at the front end of the bolt 1 and the front end of the thread, and the lubricating oil, the bracket 2 and the sealing pressure plate 4 are combined into a whole (in order to ensure the maximum adjustment, after the combination is finished, the sealing pressure plate 4 is kept to be attached to the bracket 2).
6) The center of the sealing pressure plate 4 is aligned with a leak point, and a clip-shaped hole 9 at one end of the high-strength clip-shaped fiber band is hung at one end of the bracket 2.
7) The high-strength rectangular-shaped fiber band is wound around the pipeline for one circle and is tensioned, and an appropriate rectangular-shaped hole 9 is found to be hung at the other end of the bracket 2.
8) And (3) cutting off the rest high-strength rectangular-shaped fiber band (if the pipe diameter is large, two layers of the high-strength rectangular-shaped fiber band can be hung), inserting an operating rod into the circular hole of the bolt 1, and screwing the bolt 1 until no water leakage occurs.
