Abstract
The utility model relates to a poly ethylene (PE) dredge pipe which comprises a PE dredge pipe section, a sealed joint, a connecting flange and a lining pipe. The sealed joint and the PE dredge pipe section are in an integrated structure, and the diameter of an open end of the sealed joint is greater than the diameter of the PE dredge pipe section. The connecting flange is arranged outside of the PE dredge pipe section in a sleeved mode. The lining pipe is connected with the inner wall of the sealed joint in a tightly matched mode. The end face of the lining pipe and the end face of the sealed joint are in the same plane. The PE dredge pipe has the advantages of being reliable in connection and seal, convenient to operate on spot, convenient to dismantle due to connection by the flange, and convenient to replace and recycle.
Description
Technical field
The utility model relates to a kind of PE dredging pipe.
Background technique
The PE pipe has medium density polyethylene pipe and high density polyethylene pipe, and steel pipe relatively, and construction process is simple, and certain pliability is arranged, and main is to be not used as preservative treatment, will save a large amount of operations.Not as steel pipe, the special safety clearance of noting heating power heating in the construction, and can not being exposed in the air under the sunlight, and responsive to chemical substance prevents that the leakage of sewage conduct from damaging to shortcoming with regard to mechanicalness.Quality is light, and the life-span is long, and quality only has 1/8th of iron pipe, and be five times of steel pipe working life; Have extremely strong corrosion resistance, mechanical property is excellent, and the water pressure resistance impact strength is high; Surface finishment is high, and tube wall is smooth, and fluid resistance is little, and friction factor only is 0.4; Easy construction, simple and easy quick, safe ne-leakage; Has antistatic and anti-flame retarding; Be widely used in chemical industry, the inflammable and explosive place such as combustion gas, the colliery plumbing, ventilation is with managing.The municipal tubing market of present China, plastic pipe is just in stable development, and the PE pipe occupies a tiny space, and wherein the powerful growth momentum of PE pipe pipe attracts people's attention the most.The use field of PE pipe is extensive.Wherein drain pipe and fuel tube are two maximum application markets.
The tube and tube Placement has welding process, flange connection method usually, and the flange connection method adopts flange to add sealing gasket, and the thickness of jointing is greater than tubing thickness, guaranteed that sealing is reliable, the flange connection method is that dismoutability connects, and site operation is convenient, tubing can reclaim, and has saved cost.
Summary of the invention
The purpose of this utility model is to provide a kind of PE dredging pipe, and it is simple in structure, easy to use and to connect sealing between the tube and tube reliable.
The utility model for achieving the above object technological scheme is:
A kind of PE dredging pipe comprises PE dredging pipeline section, SEALING FITTING, adpting flange, bushing pipe; Described SEALING FITTING and PE dredging pipeline section be integrated and described SEALING FITTING opening end diameter greater than the diameter of PE dredging pipeline section; Described adpting flange is enclosed within on the PE dredging pipeline section, and the inwall tight fit connection of described bushing pipe and SEALING FITTING and the end face of its end face and SEALING FITTING are within same plane.
As further improvement of the utility model: described bushing pipe is the spheroidal graphite cast iron manufacturing.
The utility model is at the two ends of PE dredging pipe, utilize mould to manufacture the large SEALING FITTING of Peng, and in the SEALING FITTING hole, connect bushing pipe, outside the PE dredging pipe, put adpting flange again, at PE dredging pipe SEALING FITTING end face sealing gasket is installed, with screw bolt and nut adpting flange is strained, it has guaranteed that joint sealing is reliable, and the flange connection method is the dismoutability connection, and site operation is convenient.The utility model is simple in structure, easy to use, has solved the connectivity problem of jointing variable thickness, has guaranteed again sealing and the operability of docking simultaneously.
Description of drawings
Fig. 1 is the structure diagram of the utility model PE dredging pipe.
Fig. 2 is the docking scheme of erection of PE dredging pipe.
Wherein: PE dredging pipeline section 1, adpting flange 2, SEALING FITTING 3, bushing pipe 4, bolt 5, nut 6, sealing gasket 7.
Embodiment
The below is further described the utility model to closing drawings and Examples.
Embodiment: as shown in Figure 1, the utility model relates to a kind of PE dredging pipe, comprises PE dredging pipeline section 1, adpting flange 2, SEALING FITTING 3, bushing pipe 4; Adpting flange 2 is enclosed within on the PE dredging pipeline section 1; Described SEALING FITTING 3 be integrated with PE dredging pipeline section 1 and described SEALING FITTING 3 opening end diameters greater than the diameter of PE dredging pipeline section 1; Be connected in the endoporus of SEALING FITTING 3 in the described bushing pipe 4 and form drive fit, and the end face of the end face of described bushing pipe 4 and SEALING FITTING 3 is within same plane; Wherein bushing pipe 4 usefulness spheroidal graphite cast iron are made.
As shown in Figure 2, relate to two PE dredging pipe docking, comprise PE dredging pipeline section 1, adpting flange 2, SEALING FITTING 3, bushing pipe 4, bolt 5, nut 6, sealing gasket 7; During installation, with the alignment of two PE dredging pipe sealing surfaces and sealing gasket 7 is installed between two seal of tube faces, at last with bolt 5 and nut 6 with adpting flange 2 tensions.
The utility model is by the design to the pipe connecting end, so that the site operation docking is convenient, and it is reliable to connect sealing; And owing to adopting flange to connect, disassemble conveniently, be convenient to again simultaneously change and reclaim, have good promotional value.
