Description
Technical field
The utility model relates to a kind of joint, relates in particular to a kind of elastic damage preventing PP-R pipe joint.
Background technique
PP-R is to being again three type polypropylene tube, has the features such as lightweight, corrosion-resistant, non-scaling, long service life.PP-R tubing is compared with pipelines such as traditional cast iron tube, Coating Steel Pipe, cement pipe, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance is easy, long service life, be widely used in building industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and cable sheath, industrial fluids conveying, agricultural irrigation; Connection between traditional PP-R pipeline is all to adopt to be directly threaded, and does not have buffering between pipeline, and the damage of joint easily occurs.
Model utility content
The purpose of this utility model provides a kind of elastic damage preventing PP-R pipe joint with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of elastic damage preventing PP-R pipe joint, described joint is arranged between two sections of PP-R pipes, described joint comprises shell, two lands, extrusion spring circle and two extension spring circles, the through hole of described enclosure is stepped, two described lands are all arranged in described shell, and be fixedly connected with one end of two sections of described PP-R pipes respectively, described extrusion spring circle is arranged between two described lands, two described extension spring circles be separately positioned on two described lands outsides and with described housing contacts.
Two lands can slide in the enclosure, and the extrusion spring circle of land both sides and extension spring circle can make two segment pipes when being squeezed or stretch, play buffer function, avoid joint to sustain damage.
Particularly, the internal diameter at described shell two ends is less than the internal diameter of described shell middle-end, and is provided with a plurality of fixed grooves on the middle-end inwall of described shell, and the outer of described land is provided with the fin corresponding with described fixed groove.
Particularly, the inwall of described land is provided with internal thread, the outer wall of described PP-R pipe one end is provided with the outside thread with described internal thread engagement, and the external diameter of described land equals the internal diameter of described shell middle-end, and the external diameter of described PP-R pipe equals the internal diameter at described shell two ends.
Fixedly fin correspondence is arranged in fixed groove, can make land in the enclosure portion do not slide, can be directly by rotation PP-R pipe, make it to be fixedly connected with land.
As preferably, described land and described PP-R pipe are provided with sealing rubber ring with the joint of described shell.
The beneficial effects of the utility model are:
In the utility model elastic damage preventing PP-R pipe joint, be provided with extrusion spring circle and extension spring circle, while making two sections of PP-R pipes if extruding occur or stretch, spring ring can play the effect of buffering, can effectively avoid joint damaged, can extend its working life.
Accompanying drawing explanation
Fig. 1 is the sectional view of elastic damage preventing PP-R pipe joint described in the utility model;
Fig. 2 is the sectional view of elastic damage preventing PP-R pipe joint described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model elastic damage preventing PP-R pipe joint, joint 20 is arranged between two sections of PP-R pipes 10, joint 20 comprises shell 1, two lands 2, extrusion spring circle 3 and two extension spring circles 4, the through hole of shell 1 inside is stepped, two lands 2 are all arranged in shell 1, and be fixedly connected with one end of two sections of PP-R pipes 10 respectively, extrusion spring circle 3 is arranged between two lands 2, two extension spring circles 4 are separately positioned on two land 2 outsides and contact with shell 1, the internal diameter at shell 1 two ends is less than the internal diameter of shell 1 middle-end, and on the middle-end inwall of shell 1, be provided with a plurality of fixed grooves 6, the outer of land 2 is provided with the fin corresponding with fixed groove 6, the inwall of land 2 is provided with internal thread, the outer wall that PP-R manages 10 one end is provided with the outside thread meshing with internal thread, and the external diameter of land 2 equals the internal diameter of shell 1 middle-end, the external diameter of PP-R pipe 10 equals the internal diameter at shell 1 two ends, land 2 and PP-R pipe 10 are provided with sealing rubber ring 5 with the joint of shell 1.
The working principle of the utility model elastic damage preventing PP-R pipe joint is as follows:
Two sections of PP-R pipe, 10 two ends from joint 20 are screwed in to joint 20, make it the outside thread of end and is connected with the internal thread of land 2 in shell 1, screw PP-R pipe 10 and land 2 are fixed; If extruding appears in two sections of PP-R pipes 10, two lands 2 move at shell 1 Nei Xiang center, and the extrusion spring circle 3 between land 2 plays buffer function; If stretching appears in two ends PP-R pipe 10, two lands 2 are in the interior outside movement of shell 1, and the extension spring circle 4 in land 2 outsides plays buffer function.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model, within all falling into protection domain of the present utility model.
