Description

PE tubular product butt joint connection structure that can alternate angle in succession

Technical Field

The utility model relates to the technical field of PE pipe connection, in particular to a butt joint connection structure capable of continuously changing angles of a PE pipe.

Background

The PE (polyethylene) plastic pipe is one of important products in the domestic water supply and drainage field due to the advantages of excellent corrosion resistance, long service life and the like. In the application process of the PE pipes for many years, the angles can be adjusted through pipe bending due to the excellent toughness of the PE pipes, but great troubles are brought to users when the angles cannot be adjusted through pipe bending for narrow space construction sites, trenchless construction, old community transformation projects and the like.

At present, the elbow with a special angle in China needs to be met by using a welded pipe fitting, but the pipe fitting product has limitations in the actual construction process, the customization period is long, the precision requirement is high, and the problem of mismatch of the wall thickness of the pipe fitting causes the large-scale popularization to be limited. Therefore, the market needs a new type of universal pipe fitting to meet the variable angle construction.

The utility model mainly aims to provide a butt joint structure of a PE pipe capable of continuously changing angles, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a but PE tubular product looks transition angle's butt joint connection structure in succession, includes that two treat the PE pipe of butt joint, every the equal fixed connection flange of one of them tip of PE pipe, PE pipe sets up with the flange slope, be equipped with the logical groove with PE pipe intercommunication on the flange, the one end that PE pipe was kept away from to the flange is equipped with the ring plate as an organic whole even, two after the ring plate butt joint with the up end shape annular groove of two flanges, be equipped with the sealing washer in the annular, two the outside of flange is equipped with the semicircle hoop of two symmetries, two be equipped with the inlay card groove in the semicircle hoop, inlay card groove and two the flange joint, two the both sides of semicircle hoop all are equipped with the otic placode as an organic whole even, two through bolt-up connection between the otic placode of semicircle hoop homonymy.

Preferably, the angle between the PE pipe and the flange is 30-60 degrees.

Preferably, the included angle between the PE pipe and the flange is 45 degrees.

Preferably, the inner diameter of the ring plate is larger than that of the through groove.

Preferably, the PE pipe and the flange are connected by electric melting or hot melting.

Preferably, the sealing ring is made of elastic materials, and the thickness of the sealing ring is slightly larger than the height of the ring groove.

Compared with the prior art, the utility model has the following beneficial effects: according to the utility model, the PE pipes are connected with the flanges in an inclined manner, the two flanges rotate relatively, the angle of the two PE pipes can be adjusted continuously, the two flanges are fixed in a sealing manner by matching the two semicircular hoops with the sealing rings, the fixing is stable, the sealing performance is good, the operation is simple, the structure is novel, and the PE pipe joint is suitable for complicated and changeable construction sites.
