Description

A pipeline sealing connector

technical field

The utility model belongs to the technical field of pipeline connection, in particular to a pipeline sealing connector.

Background technique

Pipes are generally connected by pipe connectors to avoid leakage between pipes. When connecting existing pipes, sealing tape is generally wrapped around the connection between two pipes to connect the pipes. It is convenient to improve the sealing effect of pipeline connectors. However, the sealing strip will be corroded after long-term use, which greatly reduces the sealing effect of pipeline connectors, resulting in reduced sealing performance between pipelines and inconvenient connection between pipelines. .

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a pipeline sealing connector with simple structure, high structural strength, good sealing effect and easy installation.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: a pipeline sealing connector, comprising a first pipeline and a second pipeline, a sealing body is arranged between the first pipeline and the second pipeline, and the sealing body includes a The sealing ring, the middle parts of the two sides of the sealing ring are respectively fixed with sealing pipes extending into the first pipe and the second pipe. The outer walls of the two sealing pipes are respectively provided with a number of first thread grooves along the circumferential direction. The pipes are respectively provided with first installation holes corresponding to the first thread grooves, and first countersunk bolts are respectively installed in the first installation holes and the corresponding first thread grooves. The connection between the first pipe and the second pipe The outer side is provided with a sealing shell.

The sealing shell is divided into an upper shell and a lower shell, the outer walls of the first pipeline and the second pipeline are respectively provided with a plurality of second thread grooves along the circumferential direction, and the upper shell and the lower shell are respectively provided with respective second threads. the second installation holes corresponding to the grooves, and the second countersunk head bolts are respectively installed in each of the second installation holes and the corresponding second thread grooves.

A sealing sleeve is arranged between the inner sides of the upper shell and the lower shell and the outer walls of the first pipe and the second pipe.

The joints between the two sealing tubes and the sealing ring are respectively set as conical ring structures.

The outer wall of the conical ring is provided with a plurality of sealing grooves at intervals along the circumferential direction, and the connecting surfaces of the first pipe body and the second pipe body and the conical ring are fixedly connected with sealing bumps that are adapted to each sealing groove, and each sealing The protruding block is correspondingly clamped in the sealing groove.

By adopting the above technical scheme, the utility model forms a seal between the first pipe and the second pipe through the sealing body, and the joints between the two sealing pipes of the sealing body and the sealing ring are respectively set as conical ring structures, so that the sealing body and the second pipe are respectively set as conical ring structures. The first pipe and the second pipe are closely attached, and the sealing pipe of the sealing body is fixed with the first pipe and the second pipe by the first countersunk head bolt, which is convenient for installation. The pipe is further sealed, which greatly improves its tightness.
