Abstract
The utility model relates to a pipeline connecting device for the connection of a plastic pipe and a metal pipe. A plastic pipe 1 with a shoulder table 3 is fixed on a metal flange 4 whose end part is provided with a triangular convex table ring 6 by a fission flange cover 2 through a fastener 5 to form the pipeline connecting device for the connection of a plastic pipe and a metal pipe. Compared with the existing like technology, the utility model has the advantages that the connecting problem of a plastic pipe and a metal pipe is thoroughly solved, and the pipeline connecting device for the connection of a plastic pipe and a metal pipe has good sealing performance, convenient construction, and quickness.
Description
The utility model relates to a kind of plastic tube is connected usefulness with metal tube assembling pipe joint that is used for.
The pipeline that in municipal drainage, mine and chemical industry draining, irrigation and water conservancy irrigation, remote low-pressure water delivery, uses, in the laying construction process, the bonding or electric smelting sealing-in of general employing between the plastic tube; Connection between the metal tube generally adopts welding or flange to connect, and for being connected between plastic tube and the metal tube, also not having desirable method at present and solve.
The purpose of this utility model is the assembling pipe joint that will provide a kind of plastic tube to be connected with metal tube.
The utility model is achieved in that blind flange passes through fastening piece, and the pipe of moulding of band shoulder is fixed on the end and is provided with on the metal flange of boss ring and forms.During use earlier with the Guan Yiduan that moulds of assembling pipe joint, adopts bonding or the electric smelting sealing-in other mould pipe, and with the metal end of assembling pipe joint, the employing welding method is connected with other metal tube.In the job site of tubing, blind flange is fastened on the pipe of moulding of band shoulder the end and is provided with on the metal flange of boss ring with fastening piece.Boss ring on the metal flange is pressed into is with the flexible tube end of moulding, thereby finishes the purpose of this utility model.
The utility model also can be realized like this: on the basis of above scheme, the boss ring is made triangle, its angle is 20 °-60 °, highly is the 2-10 millimeter.So, just make easier being pressed into of boss ring mould tube end, sealability is further strengthened.
The utility model also can be realized like this: on the basis of above two schemes, the blind flange split is formed respectively.So, need not be enclosed within blind flange in advance and mould in the pipe shoulder, can connect construction quickly and easily.
Accompanying drawing 1 and accompanying drawing 2 have been described an embodiment of the present utility model:
Fig. 1 is that the master of assembling pipe joint looks generalized section,
Fig. 2 is the left view of assembling pipe joint.
Below discuss embodiment of the present utility model by the accompanying drawing detail:
The assembling pipe joint internal diameter is 1000 millimeters, and blind flange 2 is two halves in 8 punishment of circle position of center line, will manage 1 with moulding of shoulder 3 by fastening piece 5, is fixed on the metal flange 4 of end band boss ring 6.Boss ring 6 is a triangle, and its angle 7 is 45 °, highly is 5 millimeters.During installation earlier with assembling pipe joint mould pipe 1 left end, other moulds pipe to adopt the electric smelting sealing-in, and with the right-hand member of the metal flange 4 of assembling pipe joint, adopts welding method to connect other metal tube.At the scene during tubing, will with justify position of center line 8 punishment be the blind flange 2 of two halves be pressed in respectively mould pipe 1 shoulder 3 left sides then, steel flanges 4 is pressed in moulds pipe 1 end, the bolt of fastening piece 5 is penetrated respectively in the hole of blind flange 2 and steel flanges 4, fastening with spring washer and nut.Triangle boss ring 6 after fastening is pressed into the end of moulding pipe 1 with flexible, forms the annular sealing strip of a sealing, thereby realizes that plastic tube is connected the task of sealing with metal tube.
Use assembling pipe joint described in the utility model, with existing similar technology phase Ratio has the problem that thorough solution plastic tube is connected with metal tube, has simultaneously sealing Performance is good, easy construction, advantage efficiently.
Claims (3)
1, a kind ofly be used for the assembling pipe joint that plastic tube is connected with metal tube, it is characterized in that blind flange (2) by fastening piece (5), will band shoulder (3) mould pipe (1) and be fixed on the end and be provided with composition on the flange (4) of boss ring (6).
2, assembling pipe joint as claimed in claim 1 is characterized in that boss ring (6) is a triangle, and its angle (7) is 20 °-160 °, highly is the 2-10 millimeter.
3, assembling pipe joint as claimed in claim 1 or 2 is characterized in that blind flange (2) is the split composition.
