Abstract
The utility model discloses a pipe joint connecting member used for the connection of flexible pipes. The pipe joint connecting member used for the connection of flexible pipes is composed of a joint body and a frapping steel sleeve. The connecting end of the joint body is in the shape of a straight pipe. A plurality of annular reverse teeth are arranged on the outer surface of the connecting end, and an annular groove is also arranged on the outer surface of the connecting end. An elastic rubber sealing ring is sheathed in the annular groove. The pipe joint connecting member used for the connection of flexible pipes has compact structure and reliable connection. The pipe joint connecting member used for the connection of flexible pipes is suitable for the connection of flexible pipes of PEX pipes, aluminum-plastic composite pipes, etc.
Description
The utility model relates to a kind of link, especially relates to the pipe joint link that a kind of flexible pipe connects usefulness.
The connection of flexible pipes such as PEX pipe, aluminium-plastic composite pipe is adopted traditional pipe fitting to connect and is very easily got loose, and the seepage phenomenon takes place.The pipe fitting that flexible pipe connection is at present used adopts rib-loop to drive circumferential opening mostly, the Tapered Cup of inner surface belt raised line moves axially, thereby generation radial contraction, make pipe produce elasticity and flexibility distortion, inner surface of tube is close to joint end outer ring and is become sealing, owing to opening ring raised line is clamp-oned the axial displacement that the tubing outer round surface stops pipe, form the connection of tubing simultaneously.Certainly will make the fitting structure profile bigger but adopt this Tapered Cup to connect, consumptive material is more, and to the more high defective of pipe internal diameter tolerance.
The purpose of this utility model is to provide a kind of compact structure, reliable pipe joint link of connection that is used to connect flexible pipe.
The utility model by fittings body, tighten up steel bushing and form, the connecting end of described fittings body is straight tube shape, the connecting end outer surface is provided with many ring-type pawls, the connecting end outer surface also is provided with annular groove, sheathed elastic rubber sealing ring in the annular groove.
The utility model connecting end outer surface is provided with two annular grooves.
Bottom of tightening up steel bushing of the present utility model is circular arc.
Major advantage of the present utility model is: the one, and the design of straight tube shape end reduces joint boundary dimension, reduced the materials consumption of joint, the ring-type pawl makes installation more reliable, after flexible pipe is tightened up the steel bushing gathering, make tubing produce certain elasticity and flexibility distortion, the flexible pipe inner wall section is clamp-oned in the pawl, pipe is improved in the reliability that is subjected to axially to pull; The 2nd, the tolerance to pipe internal diameter has been loosened in the setting of elastic rubber sealing ring, has improved the sealing that connects; The 3rd, tighten up the steel bushing bottom and be circular-arc bottom face, make tubing insert the back and have certain space with fittings body, the deformability axial displacement of link when expanded by heating can be prevented, and the electro erosion of different metal can be prevented.
Be further described below in conjunction with drawings and Examples.
Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is the decomposing schematic representation of the utility model structure;
Fig. 3 is a kind of mode of execution structural representation of the present utility model.
As shown in Figure 1 and Figure 2, the utility model is by fittings body 1 and tighten up steel bushing 5 and forms, and the connecting end 7 of fittings body 1 is straight tube shape, and connecting end 7 outer surfaces are provided with many ring-type pawls 2, and connecting end 7 outer surfaces also are provided with annular groove 3, annular groove 3 interior sheathed elastic rubber sealing rings 4.
When flexible pipe 6 and fittings body 1 join, flexible pipe 6 is enclosed within on the connecting end 7 of band shape pawl 2, force gathering by the steel bushing 5 that tightens up that is enclosed within flexible pipe 6 outsides, make flexible pipe 6 produce elasticity and plastic deformation, flexible pipe 6 is fixed on firmly on the connecting end 7 of fittings body 1.
The bottom of receiving cover steel bushing 5 is circular arc, and flexible pipe 6 inserts when tightening up between steel bushing 5 and the fittings body, can have certain clearance between fittings body 1 and the flexible pipe 6.
The utility model can be applicable to any end or the above above demultplexer joint of straight joint, elbow connection, three-way union, threeway that connects flexible pipe of an end or the like pipe fitting.
Fig. 3 has the connecting end of the utility model structure of three different-diameters on the fittings body 1.During installation, install elastic rubber sealing ring earlier, knock in the steel bushing that tightens up that matches with wooden mallet again, be enclosed within on the connecting end of fittings body after with mouth expander flexible pipe enlarging school being justified, will tighten up steel bushing with special-purpose punching press pincers at last and compress ne-leakage phenomenon during pressure testing.
The utility model is applicable to the connection of flexible pipes such as PEX pipe, aluminium-plastic composite pipe.
