Abstract

The utility model discloses a plastic drainage pipe fitting, which can be bonded without glue. The plastic drainage pipe fitting comprises an upper pipe (2), a lower pipe (6), an internal container (1), and a connecting pipe (4); wherein the internal container (1) is arranged inside the connecting pipe (4), the upper pipe (2) and the lower pipe (6) are arranged inside the internal container (1), the connecting pipe (4) is bonded with the internal container (1), the upper pipe (2) and the lower pipe (6) are directly inserted into the internal container (1), protective ring covers (3) are respectively arranged on the upper end and the lower end of the internal container (1), the internal container (1) is made of a rubber material, and the protective ring covers (3) are made of plastic. A spacing ring (5) is also arranged on the middle part of the connecting pipe (4). The plastic drainage pipe fitting can be used for non-buried indoor/outdoor spigot and socket type drainage pipes with diameter smaller than DN200, and as well as fittings such as tee fittings, elbows and pipe clamps. The plastic drainage pipe fitting solves the problem that the spigot and socket type drainage pipes can only be used for one time in case of bonding, and can be disassembled for inspection and assembled at any time; and the ductile rubber is used as inner wall of the pipe fitting, so as to solve the shortcoming of unreliability of glue sealing.

Description

The plastic draining pipe fitting

Technical field

The utility model relates to a kind of plastic draining pipe fitting.

Background technique

In the draining of indoor and outdoors such as industrial premises, civil building, often adopt plastic drain pipes such as UPVC, PVC-U, but the Placement of this tubing is bonding way.For pipe laying and prevent pipe leakage, all before pipe fitting inner wall and pipeline outer wall socket joint, smear special plastic glue.Whether there are foreign material determining pipeline whether to leak in whether evenly the smearing of glue, the pipe fitting joint socket and problem that whether piping erection is firm.In order to guarantee the piping erection quality, generally all can adopt the good glue of quality, so just caused, pipe fitting all is that disposable use is promptly scrapped basically, when in case error being installed or percolating water phenomenon being arranged, must use new pipeline and pipe fitting to reinstall, so just waste tubing, thereby increased installation cost.Therefore how the needs solution makes pipe fitting can stand repeatedly dismounting and does not influence use, the Security that the reinforced plastic drainage pipe is installed.

The model utility content:

The technical problems to be solved in the utility model is: a kind of plastic draining pipe fitting be provided, do not need glue bonding, overcome plastic pipe by bonding cause can only disposable shortcoming.

The utility model is to constitute like this: it comprises manages 2, manages 6 down, and inner bag 1 is arranged in connecting tube 4, on manage 2, manage 6 in inner bag 1 down.

Connecting tube 4 and inner bag 1 is bonding the connection, on manage 2, manage 6 down and directly insert in the inner bags 1, realize connecting by frictional force.

Upper tip and lower end at inner bag 1 have guard circle lid 3, and be aging to avoid inner bag to cause because of drenching with rain sunshine.

Inner bag 1 uses rubber material to make.

Guard circle lid 3 makes made of plastic.

Middle part at connecting tube 4 also can be provided with a spacer ring 5, can solve pipe 2, manage 6 insertion distance problem down.

The utility model can be applicable to non-the bury ground indoor and outdoor socket joint connection plastic draining pipeline of diameter less than DN200, may be used on such as in the pipe fittings such as threeway, elbow, pipe collar.

Compared with prior art, the utility model has overcome the socket joint water-drainage tube part can only disposable shortcoming when bonding, and this pipe fitting can be removed inspection at any time, install; There is ductility rubber to make inwall, also solved the insecure shortcoming of glue sealing.It is good that the utility model also has using effect, with low cost, and advantages such as reliable are installed.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Embodiment of the present utility model: the structure of socket joint connection plastic draining pipe fitting as shown in Figure 1, diameter is connected with following pipe 6 direct insertions with connection pipe fitting 4 less than the non-pipe 2 of going up that buries the plastic draining pipeline on ground of 200mm, and it installs soundness and sealing is finished by the rubber liner 1 that is ductile.

Plastics guard circle lid 3 is installed at connection pipe fitting joint socket place, with protection inner bag 1, the inner bag 1 of avoiding the ductility rubber material exposed to the sun and rain and cause aging.Guard circle lid 3 makes made of plastic.Connection pipe fitting 4 inwalls and inner bag 1 are directly bonding.The thickness of inner bag 1 is 2～5mm.

Middle part at connecting tube 4 can also be provided with spacer ring 5, can solve pipe 2, manage 6 insertion distance problem down, and can increase the rigidity of connecting tube, reduces distortion, guarantees to manage up and down the distance of insertion and inserts smoothly.
