Description

Novel pipe fitting connecting device

Technical Field

The utility model relates to a pipe fitting connecting device, a novel pipe fitting connecting device specifically says so.

Background

At present, a ductile cast iron pipe is generally adopted in a water conveying pipeline, a socket joint connection mode is adopted at most of the connection position, the connection mode needs to be installed in place, otherwise, the socket joint position can be separated, another factor causes the socket joint to be separated, namely, after the pipeline is used for a period of time, the pipeline is bent, if the pipeline is bent to a certain degree, the socket joint can be separated, and if the pipeline connection position is separated, a large amount of water loss can be caused, and even other major accidents can be caused.

Disclosure of Invention

In order to solve the above problems, the present invention provides a novel pipe connecting device.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a novel pipe fitting connecting device, including socket and bellmouth, socket and bellmouth are the extending part of adjacent butt joint pipe fitting, the one end of bellmouth becomes thick outward inclined plane to the tip gradually, and the socket is inserted in the opening of bellmouth, the welding has the round to weld on the outer lateral wall of bellmouth, the welding ring is covered with the flange of cover on the socket outward, the flange inboard narrows down gradually towards the socket direction and forms the inner inclined plane, socket one side of welding ring is provided with the fender ring of cover on the socket, one side of fender ring is the inclined plane and hugs closely on flange inboard side forms the inner inclined plane, a plurality of bolt holes of having evenly arranged respectively in the flange periphery, the gib head of gib head bolt is pressed on the outer inclined plane of bellmouth, the screw position of gib head bolt is twisted in the nut of flange one side.

The utility model has the advantages that: 1. the sealing performance and the anti-slipping performance of the flexible joint are well combined, and the installation is convenient.

2. The integral hoisting construction of one section of pipeline can be realized, and the disassembly is good.

3. The TF type self-anchored interface hook bolt cap is a blind cap, is suitable for buried pipelines, does not enter soil through screw threads, and enhances the anti-corrosion effect.
