Abstract
The utility model discloses a kind of heavy-caliber plastic pipe head connecting device, belong to the connection in underground pipes road.Heavy-caliber plastic pipe head connecting device is to realize the device that the tube head of two docking firmly connects the most hermetically.Placing waterstop outside plastic tube A with plastic tube B tube head seam circumference, glass fiber reinforced plastic pipe hoop is enclosed within outside the waterstop outside plastic tube tube head seam, and the pipe collar interface bolt tightened realizes the connection of the tube head of two docking.Two tube heads are tightly coupled together by the pipe collar in heavy-caliber plastic pipe head connecting device by interface bolt.If pipe joint has deformation, also can be corrected into consistent circle, be allowed to be precisely directed to connect.Waterstop water-swellable, by mouth of pipe joint sealing.
Description
Technical field
This utility model relates to the attachment means of the connection of a kind of plastic tube, particularly heavy-caliber plastic pipe.
Background technology
Heavy-caliber plastic pipe is as underground pipes road, and its tube head type of attachment is the most important.Prior art uses pyrocondensation belt to connect, and plastics tube head to good in pipe trench, seam crossing is wound around pyrocondensation belt, then toasts with blowtorch, and pyrocondensation belt shrinks fit sealing tube head interface.This method is simple and quick, but has a kind of defect.Using pyrocondensation belt to connect tube head interface, bad mechanical strength, in pipeline under the huge heavy weight pressure of liquid of conveying, pipe trench bottom solum once occurs sedimentation that interface will be occurred to rupture, and leads to leakage accident.Additionally, the plastic tube mouth of pipe is producing, transports, depositing, it may happen that deformation in blowtorch baking, two mouth of pipe docking sternly also do not leave the hidden danger having an accident.Pipeline is embedded in underground and is difficult to discovery simultaneously, brings difficulty for fixing a breakdown.
Summary of the invention
The purpose of this utility model is a kind of heavy-caliber plastic pipe head connecting device of design, makes tube head connect the most firmly but also seal, overcomes the problem that prior art exists.Such technical scheme is have employed: heavy-caliber plastic pipe head connecting device, is to realize the device that the tube head of two docking firmly connects the most hermetically for reaching this purpose.Placing waterstop outside plastic tube A with plastic tube B tube head seam circumference, glass fiber reinforced plastic pipe hoop is enclosed within outside the waterstop outside plastic tube tube head seam, and the pipe collar interface bolt tightened realizes the connection of the tube head of two docking.
Glass fiber reinforced plastic pipe hoop is the envelope plastic tube tube head ring set with opening of a week, is provided with bolt plate on opening edge, on the inner surface that ring set is relative with tube head, has a circle to deposit the depression of waterstop.
Pipe collar in heavy-caliber plastic pipe head connecting device has enough intensity, is tightly coupled together by two tube heads by pipe collar interface bolt.If pipe joint has deformation, also can be corrected into consistent circle, be allowed to be precisely directed to connect.Waterstop water-swellable, by mouth of pipe joint sealing.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of heavy-caliber plastic pipe head connecting device；
Fig. 2 is the view profile that tube head connects, and represents the annexation of pipe collar and plastic tube.
Detailed description of the invention: be further described below in conjunction with the accompanying drawings.
As shown in drawings, heavy-caliber plastic pipe head connecting device, is to realize the device that the tube head of two docking firmly connects the most hermetically.Putting waterstop 3 at plastic tube A1 with outside plastic tube B5 tube head seam circumference, glass fiber reinforced plastic pipe hoop 2 is enclosed within outside waterstop, and the tube head that two dock is linked together by the pipe collar interface bolt 4 tightened.
Glass fiber reinforced plastic pipe hoop 2 is the envelope plastic tube tube head ring set with opening of a week, is provided with bolt plate on opening, on the inner surface that ring set is relative with tube head, has a circle to deposit the depression of waterstop.Waterstop is limited in the gap between the waterstop depression of plastic tube tube head seam excircle and pipe collar.Waterstop water-swellable, by joint sealing.
Obviously, the described above of the application is only for clearly demonstrating the application example, and is not the restriction to presently filed embodiment.The obvious row changed or change the protection domain still in the application that every technical scheme belonging to the application is amplified out.
