Summary of the invention
Problem to be solved in the utility model is to provide a kind of simple in structure, flexible pressure sealing tackling that plugging effect is good, is especially suitable for the emergency repair leak stopping of the metallic conduit with 3 layers of PE.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flexible pressure sealing tackling, comprise rubber pad and restraint zone, described rubber pad is divided into three layers, be followed successively by from the bottom up plugged zone, sealing layer and stress layer, respectively be provided with a slat gum band in the both sides of described plugged zone, the rubber tape of described plugged zone both sides forms the annular of a sealing after being connected by grafting, on the rubber tape of described plugged zone both sides, be respectively equipped with two jacks that can make stress layer insert near plugged zone place, the upper surface of described sealing layer is divided into multiple sealing grids and is respectively provided with a plug at four drift angle places of upper surface, lower surface and multiple sealing grids corresponding part are groove, the both sides of described stress layer are respectively provided with two plugs corresponding with jack on the rubber tape of plugged zone both sides, the upper surface of described stress layer is provided with the equally distributed square of multiple arc convex, the power that restraint zone is applied on monoblock stress layer is evenly distributed, on bending or irregular surface, effect is more outstanding, four drift angle places of the lower surface of described stress layer are provided with the jack corresponding with plug on four drift angles of sealing layer, the two ends of described restraint zone are respectively provided with a pull bar, respectively offer two tie rod holes on described pull bar, in the tie rod hole of restraint zone one end, are installed with fastening screw.
Further, described plugged zone is hydrogenated nitrile-butadiene rubber, and its effect is directly to contact with the leakage point of pipeline, heatproof, endurance, acid-alkali-corrosive-resisting, and character is softer.
Further, the upper surface of described sealing layer is divided into nine lattice, and effect is that top is pressed on plugged zone, strengthens the plugging effect of plugged zone, and character is harder.
Further, described sealing layer and stress layer are plastic material.
Further, described restraint zone adopts aramid fibre braiding, and on described restraint zone, also cover has the relatively more lubricated thick plastic pellicle of one deck, in the process of clamping bolt, between restraint zone meeting and pipeline, produce very large frictional force, this layer film can reduce this frictional force, promotes the effect of leak stopping.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, can not get angry pipeline is carried out to non-stop plugging fast, the rubber pad of special construction can be blocked the leakage up to 10MPa, be particularly useful for the shutoff of the irregularly shaped high pressure pipe lines such as bend pipe, reducing, weld seam, have small product size little, lightweight, be easy to carry and the advantage such as operation, plugging effect be good.
