Description

Inside has the anti-oxidant PPR pipe of desilting unit

Technical field

The utility model relates to the anti-oxidant PPR pipe that a kind of inside has desilting unit.

Background technique

PP-R (polypropylenerandom) to cry not only three type polypropylene tube and but also be polypropylene random copolymer pipe or PPR pipe, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, the advantage such as inner wall smooth non-scaling, construction and 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.PP-R pipe adopts atactic copolymerized polypropene through being extruded as tubing, and injection moulding becomes pipe fitting.

Its defect is that Long-Time Service tube wall easily accumulates the foreign material such as mud, is not easy dredging when accumulating to a certain extent.

Summary of the invention

Problem to be solved in the utility model is to provide the anti-oxidant PPR pipe that a kind of inside has desilting unit, is applicable to overcoming deficiency of the prior art.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: inside has the anti-oxidant PPR pipe of desilting unit, comprise body, described body has EVOH oxidation prevention layer, the inwall of described body is around the uniform multiple chute running through described body both ends of the surface of axis of described body, there is in described body desilting unit, described desilting unit comprises web plate, and cross, described web plate is positioned at the top of described cross, the edge of described web plate has the slide block corresponding with described chute, described slide block is limited in described chute, and can slide along the direction of described chute,

The end of described cross is limited in along described slide in described chute, and in described chute, between described cross and described web plate, place has step surface, and described slide block can contact with described step surface;

Described slide block has through hole, described cross has pull bar, one end of described pull bar is fixed on described cross, and the other end extends through the end face of described through hole towards described body.

Further, the end of described body has groove, and the end of described pull bar has the end block vertical with described pull bar, and described end block can be positioned in described groove.

The advantage that the utility model has and good effect are: owing to adopting technique scheme, facilitate the desilting of pipe inside to operate, avoid the blocking of pipeline.

Embodiment

As shown in the figure, the utility model provides a kind of inside to have the anti-oxidant PPR pipe of desilting unit, comprise body 1, body 1 has EVOH oxidation prevention layer, the inwall of body 1 is around the uniform multiple chute 4 running through body 1 both ends of the surface of axis of body 1, there is in body 1 desilting unit, desilting unit comprises web plate 2 and cross 3, and web plate 2 is positioned at the top of cross 3, and the edge of web plate 2 has the slide block 5 corresponding with chute 4, slide block 5 is limited in chute 4, and can slide along the direction of chute 4;

The end of cross 3 is limited in chute 4 slides along chute 4, and in chute 4, between cross 3 and web plate 2, place has step surface 6, and slide block 5 can contact with step surface 6;

Slide block 5 has through hole, cross 3 has pull bar 7, one end of pull bar 7 is fixed on cross 3, and the other end extends through the end face of through hole towards body 1.

Web plate 2 relies on step surface to be positioned the middle part of body 1, mud can retain by web plate 2, when there is blocking in web plate 2, pull bar 7 can be pulled out, now cross 3 moves up and web plate 2 is pushed out to the port of body 1, be convenient to clear up mud, after cleaning out, web plate 2 resetted in step surface 6 place.

The end of body 1 has groove 8, and the end of pull bar 7 has the end block 9 vertical with pull bar 7, and end block 9 can be positioned in groove 8.End block 9 is positioned in groove 8 location that can realize cross 3, avoids it to drop in body 1 and stretch out, cannot manipulate it.

Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
