Abstract
The utility model discloses a plug-in type water-expansion sealed connecting device for winding pipes, and aims at providing a plug-in type water-expansion sealed connecting device for winding pipes with high construction speed, good sealing property and reliable connection. The plug-in type water-expansion sealed connecting device for winding pipes comprises a left straight-wall winding pipe and a right straight-wall winding pipe which are butted with each other, and is characterized in that a connecting sleeve is welded on the periphery of the left winding pipe or the right winding pipe at the seam part, a plug-in unit at one end of the other winding pipe is positioned in a plugging port of the connecting sleeve, an annular groove provided with a water-expansion sealing ring is arranged on the inner circumferential surface of the plugging port, and the water-expansion sealing ring is arranged in the annular groove. The connecting sleeve and the winding pipes are fabricated into pre-fabricated parts, and the connecting sleeve is not hollow, has good rigidity, and is not deformed easily, therefore, the mechanical construction mode can be adopted for plugging and installing, the sealing part is not displaced; and the water-expansion sealing ring expands when contacting water, thus improving the sealing effect. The plug-in type water-expansion sealed connecting device for the winding pipes has the advantages of simple structure, convenient construction, good sealing property and low cost.
Description
Technical field
The invention belongs to a kind of connection set of pipe, more specifically to the entwining tube plug-in type water swelling seal connection of buried usefulness.
Background technique
At municipal drainage, building outdoor drainage, bury the defeated draining in farmland, ground, discharge of industrial wastes, road drainage, sewage treatment works, sports ground, square engineering drainage and electrical telecommunication engineering etc.; often can use the empty wall winding tube that buries ground; it is a kind of hollow-wall drainpipe material that adopts hot winding shaping process to make, this tubing to the discharging of water body, save the energy, reduce to pollute, the protection environment is significant.It is a kind of straight wall pipe, the method that connects has Electric thermal smelting belt connection, pipe clamp to connect usually, heat-shrinkable tube connects, flange connects, after patent ZL01253894.9 entwining tube connected water swelling seal connection is arranged again, it is to put by the connection of Hollow wall tube tissue in the seam outer rim at two entwining tube to accept cover, connection accept the cover and two entwining tube between the rubber heelpiece is set respectively, the cushion rubber of water-swellable is installed on the rubber heelpiece.Such linkage structure is owing to connect that to accept cover also be Hollow wall tube, and the relatively poor easy deformation in transportation and in installing of rigidity is accepted cover, the rubber heelpiece is shifted easily in the grafting process that empty wall winding tube is installed, and complex structure, the sealing of pipeline is poor, and seepage takes place easily, and also trouble is installed.
Summary of the invention
The present invention has overcome shortcoming of the prior art, provides that a kind of speed of application is fast, good airproof performance, the reliable entwining tube plug-in type of connection water swelling seal connection.
In order to solve the problems of the technologies described above, the utility model be achieved in that it include about the straight wall winding tube of two butt joints, it is characterized in that on the left side of seam crossing entwining tube or the right entwining tube cylindrical, being welded with connecting sleeve, one end plug-in unit of another root entwining tube is in the interface of connecting sleeve, on the inner peripheral surface of interface, be shaped on the annular groove that the water swelling seal ring is installed, the water swelling seal ring is installed in annular groove.
Described water swelling seal ring is made with dilatable water swelling rubber after running into water.Described water swelling seal ring is a rectangle, with internal surface that straight wall winding tube contacts on be shaped on the prominent muscle of 1-3 bar.Be shaped on the annular groove that the water swelling seal ring is installed on the inner peripheral surface of described interface the 1-2 bar is arranged.
According to above-mentioned entwining tube plug-in type water swelling seal connection, because connecting sleeve and entwining tube are made prefabricated component, and connecting sleeve is non-hollow piece, good rigidly, not yielding, in the grafting installation, can adopt mechanized construction, Sealing can not be shifted, used water swelling seal ring can expand after running into water, and improves sealing effect.Have simple in structure, easy construction, good airproof performance, advantage that cost is low.
Description of drawings
Fig. 1 is the structural representation of entwining tube plug-in type water swelling seal connection;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1;
