Description
Technical field
The utility model relates to a kind of PP-R pipe joint, relates in particular to a kind of multi-way PP-R and manages stacked joint.
Background technique
PP-R is to being again three type polypropylene tube, there is 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; Traditional PP-R pipe connector adopts elbow or tee union more, if in the time of need to there is more branch in certain part, need to use a plurality of tee unions, but because the unlinkability between joint and joint, need between each joint, add PP-R pipe, can cause like this this segment pipe joint too much, the fault such as easily occur leaking.
Model utility content
The purpose of this utility model provides a kind of multi-way PP-R to manage stacked 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 multi-way PP-R manages stacked joint, described stacked joint comprises offtake and the connecting head that a plurality of and same footpath tee union is similar, described offtake is provided with the first outlet, the second outlet and the 3rd outlet, in described the first outlet and described the second outlet, be provided with connecting ring, in described the 3rd outlet, be provided with connecting groove, described in one of them, first of offtake the outlet exports with the 3rd of offtake described in another the described stacked joint that is composed of a fixed connection, and described connecting head is connected in the 3rd outlet of described stacked connector end.
Particularly, the two ends of described connecting head are the connecting ring identical with the described connecting ring of described offtake, and the middle-end of described connecting head is the annulus equating with described the 3rd outlet external diameter.
When needs are used multiple-pass joint, a plurality of offtakes can be connected in series successively, at its end, connect again connecting head, can reach how logical effect.
Particularly, the outside of the described connecting ring in described the first outlet and described the second outlet is provided with outside thread, on the described connecting groove in described the 3rd outlet, is provided with internal thread.
In order to make to adopt interference fit between PP-R pipe and stacked joint, the external diameter of described connecting ring is greater than the internal diameter of the internal diameter of described PP-R pipe and the connecting groove of described the 3rd outlet.
Further, joint between joint between described offtake and described stacked joint and described PP-R pipe is provided with seal arrangement, described seal arrangement comprises sealing rubber ring and sealing hoop, described sealing rubber ring is arranged on each joint of described stacked joint, and described sealing hoop is arranged on the outside of described sealing rubber ring and uses bolt that described sealing rubber ring is clamped.
Preferably, described connecting ring and described sealing hoop are Hard Alloy Steel.
The beneficial effects of the utility model are:
The utility model multi-way PP-R manages the number of a plurality of offtakes of stacked joint can carry out free control as required, with only there being a joint between time-division contact and offtake, can effectively reduce the number of interface, reduces leakage accident incidence rate.
Accompanying drawing explanation
Fig. 1 is the connection diagram that multi-way PP-R described in the utility model manages stacked joint;
Fig. 2 is the sectional view that multi-way PP-R described in the utility model manages stacked joint;
Fig. 3 is the structural representation of seal arrangement 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 multi-way PP-R manages stacked joint, stacked joint comprises offtake 1 and the connecting head 5 that a plurality of and same footpath tee union is similar, offtake 1 is provided with the first outlet 11, the second outlet the 12 and the 3rd outlet 13, in first outlet the 11 and second outlet 12, be provided with connecting ring 2, in the 3rd outlet 13, be provided with connecting groove 3, the 3rd outlet 13 stacked joints that are composed of a fixed connection of the first outlet 11 of one of them offtake 1 and another offtake 1, connecting head 5 is connected in the 3rd outlet 13 of stacked connector end, the two ends of connecting head 5 are the connecting ring 2 identical with the connecting ring 2 of offtake 1, the middle-end of connecting head 5 is the annulus equating with the 3rd outlet 13 external diameters, the outside of the connecting ring 2 in first outlet the 11 and second outlet 12 is provided with outside thread, on connecting groove 3 in the 3rd outlet 13, be provided with internal thread, the external diameter of connecting ring 2 is greater than the internal diameter of the internal diameter of PP-R pipe 4 and the connecting groove 3 of the 3rd outlet 13.
