Abstract
The utility model relates to a pipe is dredged to polyethylene, include that the PE pipe that the extrusion molding takes shape personally experiences sth. Part of the body and inlays the nodular cast iron layer of making on the PE pipe body, wherein the fixed link that is provided with in nodular cast iron layer outer end connect adjacent installation body. The utility model discloses because full pipe adopts high density polyethylene, makes tubular product through extrusion molding technology again, inlaying into through the heating at last, nodular cast iron is formed by connecting. Because the wearability of high density PE pipe 4 times of the iron and steel, has the advantage lighter than steel pipe matter moreover, the steel pipe has consequently been replaced by a large scale in power plant's coal ash transport, ore sand, river course dredging engineering. Simultaneously the utility model discloses the nodular cast iron layer sets up the site operation of being more convenient for with the link is fixed.
Description
Technical field
The utility model relates to delivery line, refers in particular to a kind of polyethylene dredging pipe being applicable to the drain facilities such as municipal sewage treatment.
Background technique
At present, the city even burden of rural sewage treatment, rainwater-collecting etc. drain facility are more and more heavier, are also more and more higher to the performance requirement of drain facility.The ring stiffness of delivery line, impact strength, transport breakage, working life, connection sealing ne-leakage, be convenient to install, engineering comprehensive cost can not be all the problem that this type of piping design needs to consider higher than cement pipe etc.Because polyethylene pipe has good physical and mechanical property and safe and reliable sanitation performance, its main feature be lightweight, intensity is high, acid-resistant anti-corrosion, resistance to compression, easy construction, materials economize, 50 years can be reached working life with first-class advantage, belong to environmental protection high-new technology products, therefore promoted widely and use.Dredging pipe, as the bigbore delivery line of one, is installed easy to connect, is the problem first needing to solve.Publication number 102878378A discloses a kind of PE dredging pipe, and adopt flange method to connect, site operation is convenient.But program flange is enclosed within pipeline section, can arbitrarily movement on pipeline section, because the movable part on body make troubles to transport and carrying in transport or handling process, simultaneously because the not confirmatory of flange position also easily causes carrying to damage.
Summary of the invention
The purpose of this utility model is for the shortcoming existed in background technique and problem in addition improvement and bring new ideas, provides a kind of structure simple, polyethylene dredging pipe easy for installation.
To be that structure is a kind of comprise the polyethylene dredging pipe that polyethylene body that extrusion molding is shaped and edge are formed on spheroidal graphite cast iron layer on polyethylene body to the technical solution of the utility model, wherein said spheroidal graphite cast iron layer outer end is fixedly installed connecting end and connects adjacent installation body, and adjacent connecting ends arranges sealing gasket or seal ring seals.
Wherein in an embodiment, described spheroidal graphite cast iron layer is arranged at the two ends of polyethylene body, and the outer end of two spheroidal graphite cast iron layers arranges connecting end.
Wherein in an embodiment, described spheroidal graphite cast iron layer is arranged at the inwall of polyethylene body, and its two ends of stretching out polyethylene body arrange connecting end.
Wherein in an embodiment, described connecting end is flanged connecting structure, and flanged connecting structure is the preferred linkage structure of connecting end.
Wherein in an embodiment, described connecting end is screw connection structure.
Wherein in an embodiment, described connecting end is socket joint linkage structure.
Wherein in an embodiment, described connecting end is groove linkage structure.
Wherein in an embodiment, the outer end of described polyethylene body is provided with slideproof tooth.
Advantage of the present utility model and beneficial effect:
The utility model adopts high-density polyethylene material due to full pipe, then makes tubing through extrusion process, eventually passes heating and inlays and be formed by connecting into spheroidal graphite cast iron.Wear resistance due to high density PE pipe is 4 times of iron and steel, and has the advantage than steel pipe light weight, and therefore in coal ash of power plant conveying, ore in sand form, training of river channel engineering, large size substitutes steel pipe.The utility model spheroidal graphite cast iron layer and connecting end are fixedly installed simultaneously, site operation of being more convenient for.The utility model makes selection and the moulding process of material, make body stable chemical nature, there is good electrical insulating property, ageing-resistant strong with ESCR ability, serviceability temperature wide ranges, and there is good comprehensive mechanical performance, bearing capacity is strong, integration engineering cost has more advantage, can save substantial contribution and engineering time for users.
Accompanying drawing explanation
Fig. 1 is the utility model perspective view.
Embodiment
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.First-selected embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, the object of these embodiments is provided to be make to disclosure of the present utility model more thoroughly comprehensively.
It should be noted that, when element is considered to " setting " on another element, it can be directly arrange or be connected on another element or may there is centering elements simultaneously.
Unless otherwise defined, all technology used herein are identical with the implication that those skilled in the art of the present utility model understand usually with scientific terminology.The term used in specification, just in order to describe concrete enforcement object, is not intended to be restriction the utility model.
As shown in Figure 1, this dredging pipe comprises inlays the spheroidal graphite cast iron layer 2 into polyethylene body 1 by the polyethylene body 1 of high-density polyethylene material extrusion moulding with by heating process, and the outer end of spheroidal graphite cast iron layer 2 is provided with connecting end 3.This connecting end 3 is flange-type structure.During site operation, only need place seal ring or the sealing gasket of corresponding size between adjacent two connecting ends 3, then fix with bolt, install very convenient.As shown in Figure 1, the outer wall of polyethylene body 1 is also provided with slideproof tooth 4, is convenient to load and unload handling, accelerates construction speed, also can prevent the security incident of pipeline ways from occurring.
Embodiment described in the utility model is only the description carried out preferred implementation of the present utility model; not the utility model design and scope are limited; under the prerequisite not departing from the utility model design philosophy; the various modification that in related domain, engineers and technicians make the technical solution of the utility model and improvement; protection domain of the present utility model all should be fallen into; the technology contents of the utility model request protection, all records in detail in the claims.
