Abstract
The utility model discloses an adapting form pipe jointing device used for a plastic pipe, comprising a pipe joint which has a bell and spigot; one end of the pipe is inserted into the bell and spigot; the opening part of the insert is also provided with a ring trough used for enlarging the bell and spigot in the radial direction; the ring trough is provided with a trough bottom; the ring trough is internally provided with a ring-shaped sealing ring; fasteners around the pipe are arranged inside the ring trough at the internal side of the end surface of the sealing ring; the pipe joint is also provided with a pressing part; the position of the pressing part which is arranged on the end surface of the external side of the sealing ring is provided with a convex part which is tightly pressed on the external side end surface of the sealing ring along the axial direction. The adapting form pipe jointing device used for a plastic pipe has simple operation and no professional level restriction to the operator, has wide applicable situations such as aloft work, flammable and explosive articles and pipeline connection of chemical products; the thread is closely pressed and is not easy to be loosened, thus leading to firm and reliable sealing of the adapting form pipe jointing device.
Description
Technical field
The utility model relates to a kind of spigot and socket type pipeline connecting parts of plastic pipe.
Background technique
Being tightly connected between the spigot and socket type pipe joint that mainly is used in threeway, elbow, flange, application such as direct and the plastic pipe put in the tipping of the spigot and socket type pipe of plastic pipe.Being tightly connected between existing spigot and socket type pipe joint and the plastic pipe mainly is to rely on " hot blast welding ", " thermosol connection ", " glue connection " mode to seal.The drawback of " hot blast welding " is can't install in inflammable and explosive place; It is not quick detachable after welding finishes; Weld seam is not withstand voltage, easy to leak.The drawback of " thermosol connection " is, when the pipeline more than two carries out doubling installation and pipeline when carrying out high-lift operation, the thermosol workpiece can't use.The drawback of " glue connection " is: as the fluid in the pipeline is chemical product, and chemical product might react with glue, causes to connect to come off.And these sealing means, complex process has certain requirement to workmen's technical merit, implements inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of occasion qualification simple in structure, no, installation spigot and socket type pipe tipping quick, the reliable sealing plastic pipe is put.
Designed a kind of spigot and socket type pipe tipping of plastic pipe puts according to above-mentioned purpose, comprise pipe joint, described pipe joint has joint socket, one end of tubing is inserted in the described joint socket, the opening portion of described joint socket also offers described joint socket is radially become big annular groove, described annular groove is coaxial with described joint socket, and described annular groove has bottom land; Be provided with the seal ring of annular in the described annular groove, the inner circumferential surface of described seal ring fits tightly mutually with the external peripheral surface of described tubing, and the external peripheral surface of described seal ring fits tightly mutually with the bottom land of described annular groove; Is provided with fixed block around described tubing in the annular groove of the inboard end face inboard of described seal ring, fits tightly mutually between the inboard end face of described fixed block and described seal ring and the described bottom land; Also be provided with compressing member on the described pipe joint, the end, the outside that is positioned at described seal ring on the described compressing member is provided with protuberance, and described protuberance is pressed on the outside end face of described seal ring vertically.
Described fixed block is a part ring-shaped member of having offered opening.Described fixed block is a rigid material.Described fixed block external peripheral surface has the conical surface that reduces gradually from outer diameter inwards.Described protuberance is a ring-type, and the radial thickness of the ring of described protuberance is less than the radial thickness of described seal ring.Described compressing member thread bush is connected on the external peripheral surface of described pipe joint.
Because the employing of technique scheme the utlity model has following advantage: the utility model in use, treat tubing insertion tube joint after, compress seal ring with compressing member and get final product, simple to operate, operator are not had level limit; The application is extensive, and the pipeline of no matter high-lift operation, combustible and explosive articles, chemical product connects occasion and can use; Screw thread closely compresses, and is difficult for loosely, seals solid and reliable.

Embodiment
Below in conjunction with accompanying drawing and concrete mode of execution the utility model is described in further detail:
A kind of spigot and socket type pipe tipping of plastic pipe is put, and comprises pipe joint 1, and described pipe joint 1 has joint socket 3, and an end of tubing 2 is inserted in the described joint socket 3.The opening portion of described joint socket 3 also offers described joint socket 3 is radially become big annular groove 4, and described annular groove 4 is coaxial with described joint socket 3, and described annular groove 4 has bottom land 41.Be provided with the seal ring 5 of annular in the described annular groove 4, the inner circumferential surface of described seal ring 5 fits tightly mutually with the external peripheral surface of described tubing 2, and the external peripheral surface of described seal ring 5 fits tightly mutually with the bottom land 41 of described annular groove 4.Be provided with fixed block 6 around described tubing 2 in the annular groove 4 of the inboard end face inboard of described seal ring 5, fit tightly mutually between the inboard end face of described fixed block 6 and described seal ring 5 and the described bottom land 41.Also be provided with compressing member 7 on the described pipe joint 1, the end, the outside that is positioned at described seal ring 5 on the described compressing member 7 is provided with protuberance 8, and described protuberance 8 is pressed on the outside end face of described seal ring 5 vertically.
Described fixed block 6 is for having offered the part ring-shaped member of opening 61, and be rigid material, described fixed block 6 external peripheral surfaces have the conical surface that reduces gradually from outer diameter inwards, and this makes described fixed block 6 can better carry the pressure of the inboard end face of described seal ring 5.
Described compressing member 7 thread bushs are connected on the external peripheral surface of described pipe joint 1, guarantee that described compressing member 7 firmly is connected with described pipe joint 1.Described protuberance 8 is a ring-type, and the radial thickness of the ring of described protuberance 8 guarantees that less than the radial thickness of described seal ring 5 described protuberance 8 can be resisted against on the outside end face of described seal ring 5.
