Description
Technical field
The utility model relates to a kind of pipe joint, is specifically related to a kind of multiple tube link.
Background technique
In prior art, pipeline is widely used the conveying in various fluids, because the oxygen in fluid has corrosive action to pipeline, so in order to extend the working life of pipeline and to increase the corrosion resistance of pipeline, conventionally can adopt corrosion-resistant material to make pipeline, as corrosion-resistant macromolecular material or zinc, copper etc., certainly, the price of these resistant materials is also wanted more expensive than common steel, and the intensity of pure macromolecular material can not be compared with steel, so conventionally can be with common iron as base material, at the compound last layer anti-corrosion layer of its appearance, so, provide cost savings and increased the corrosion resistance of pipeline.But, this composite pipe normally connects several pipelines when connection with several logical links, and the shortcoming of composite pipe maximum is often to occur even break-off of interfacial corrosion between the anti-corrosion layer of its port and base material, its end of pipeline that common like this Placement connects still fully contacts with fluid, and the end of multiple tube still can be corroded.
Model utility content
Main purpose of the present utility model be to provide a kind of assemble convenient, can increase the composite pipe multiple tube link in working life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multiple tube link, comprise adpting flange, the position that described adpting flange contacts with pipe end arranges pipe outer shield and the interior guard shield of pipe that tube wall can be surrounded, and in pipe outer shield and pipe, between guard shield, the seal ring that pipe end can be wrapped is set.
That is to say that two multiple tubes connect by flange; manage interior guard shield and pipe outer shield and arrange on flange; in pipe, between guard shield and pipe outer shield, form groove; the end of multiple tube is placed in this groove; inside grooves is provided with seal ring, makes like this end of multiple tube be managed interior guard shield and pipe outer shield and seal ring and does not protect and corrode with pipeline inner fluid.
Further, described seal ring is U-shaped seal ring.That is to say that seal ring can further be surrounded the end of multiple tube to play further seal action.
Further, described pipe outer shield is long along the length of pipeline axial along guard shield in the Length Ratio pipe of pipeline axial.
Further, in described pipe, the end away from flange of guard shield more approaches tube wall than the position of nearly flange.That is to say pipe in guard shield not parallel with tube wall, but end towards tube wall tilt, this can further extend the working life of multiple tube.
Further, the screw thread that the inwall setting of described pipe outer shield coordinates with pipeline outer wall.That is to say on the curved surface that pipeline outer wall contacts with pipe outer shield screw thread is set, this screw thread matches with the screw thread on pipeline outer wall surface, so just adpting flange can be screwed on composite pipe, and this Placement simply might as well operation for the processing of pipeline.
Further, the screw thread that in described pipe, the setting of guard shield outer wall coordinates with inner-walls of duct.That is to say in inner-walls of duct and pipe, on the curved surface that contacts of guard shield, screw thread is set, this screw thread matches with the screw thread on inner-walls of duct surface, so just adpting flange can be screwed on composite pipe.
Further, between described adpting flange connecting end surface, pad is set.Pad can be flexible plastic material, plays further seal for pipe joints effect between the adpting flange end face of two pipelines.
The utility model couples together two multiple tubes by two adpting flanges that are simply provided with guard shield in pipe outer shield and pipe, by guard shield and seal ring, secondary seal is carried out in composite pipe end, avoid the composite pipe end contact being easily corroded to fluid, the life-span of composite pipe is extended greatly.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of multiple tube link of the utility model.
Embodiment
Be described as follows with reference to Fig. 1: a kind of multiple tube link, comprise adpting flange 6, the position that described adpting flange 6 contacts with pipe end arranges pipe outer shield 1 and the interior guard shield 3 of pipe that tube wall 5 can be surrounded, and in pipe outer shield 1 and pipe, between guard shield 3, the seal ring 4 that pipe end can be wrapped is set; Further, described seal ring 4 is U-shaped seal ring 4; Further, described pipe outer shield 1 is long along the length of pipeline axial along guard shield 3 in the Length Ratio pipe of pipeline axial; Further, in described pipe, the end away from flange of guard shield 3 more approaches tube wall 5 than the position of nearly flange; Further, the screw thread that the inwall setting of described pipe outer shield 1 coordinates with pipeline outer wall; Further, the screw thread that in described pipe, guard shield 3 outer wall settings coordinate with inner-walls of duct; Further, between described adpting flange 6 connecting end surfaces, pad 7 is set.
In conjunction with Fig. 1 and specifically use step to describe the described preferred version of the utility model:
The inside and outside wall car of composite pipe end is gone out to screw thread, U-shaped seal ring 4 is placed in the circular groove bottom that in pipe outer shield 1 and pipe, guard shield 3 is encircled a city on adpting flange 6, the opening side of U-shaped seal ring 4 is towards slot opening side, adpting flange 6 is covered on composite pipe end face, adpting flange 6 is rotated, screw thread in pipe outer shield 1 and pipe on guard shield 3 and the screw-thread fit of composite pipe end tube wall 5 are tightened, and this sampling composite tube end is sealed by the space that in U-shaped seal ring 4, pipe outer shield 1 and pipe, guard shield 3 is encircled a city.Another root multiple tube is so operation also, then by the end face alignment of two adpting flanges 6, middlely places a pad 7, is screwed into bolt two pipelines are linked together by being arranged on the flange fixed hole 2 of end face of adpting flange 6.
