Abstract

The utility model discloses a connecting piece for connecting multi-channel bellows, which comprises two flanges and an inner pipe connecting piece. Each flange is provided with a thread connecting end which is used for being connected with a multi-channel bellows outer pipe, and the inner pipe connecting piece is used for being connected a multi-channel bellows inner pipe so as to fix the position of an inner pipe and guarantee the inner pipe to keep coaxial. In order to achieve sealing effects, sealing rings are arranged at the ends of flange faces and pipes, finally, three parts are fastened by bolts to achieve a connecting purpose. The connecting piece for connecting multi-channel bellows is small in structural parts, convenient and fast in assembly.

Description

A connecting piece for connecting multi-channel bellows

technical field

The utility model relates to the connection field of multi-channel corrugated pipes, in particular to a connecting piece used for connecting multi-channel corrugated pipes. the

Background technique

At present, the connection of multi-channel corrugated pipes in China mainly relies on inspection wells, and there is no special connector for multi-channel corrugated pipes. The method of connecting inspection wells is only suitable for outdoor long-distance connections, and it is not applicable when the pipeline crosses roadbeds or mountains. , Furthermore, the inspection well connection does not meet the needs of short distances or laying in buildings. the

Although there are connectors specially used for multi-channel corrugated pipes in foreign countries, they adopt a compression-type connection method, which involves more components and special operating tools, and is relatively cumbersome to use. the

Contents of the invention

The purpose of the invention of the utility model is to provide a connecting piece for connecting multi-channel bellows with simple structure and convenient connection. the

In order to achieve the first object of the invention of the utility model, the utility model adopts the following technical solution: a connector for connecting multi-channel bellows, the connector includes two flanges and an inner pipe connector, the inner The middle part of the pipe connector is provided with communication holes equal to the number of multi-channel corrugated pipes to be connected, and the inner pipe connector is installed in the middle of the two flanges and connected with the two flanges by screws. The connecting end of the multi-channel corrugated pipe is provided with a flange, and the connecting channel of the inner pipe connector connects the adjacent multi-channel corrugated pipes. Ensure the coaxial function of the inner tube, and then fasten the flange plate and the inner tube connector to realize the connection of multi-channel bellows, the structure is simple, and the connection is quick and convenient. the

The flange plate is provided with a threaded structure connected with the multi-channel corrugated pipe, and the flange plate and the multi-channel corrugated pipe are connected by threads, and the connection is simple and fast. the

A sealing ring is arranged between the flange plate and the inner pipe connecting piece, and the sealing effect is good. the

The beneficial effects of the utility model: few components are involved, no special operating tools are needed, the construction speed is fast, and the sealing effect is good. the

In the figure: 1-flange, 2-inner pipe connector, 3-gasket, 4-sealing ring, 5-screw, 22-communication hole. the

Detailed ways

As shown in Figure 1, the connector for connecting multi-channel bellows described in the utility model includes two flanges 1 and an inner tube connector 2, the middle part of the inner tube connector 2 is provided with a There are communication holes 22 with the same number of multi-channel corrugated pipes. The inner pipe connector 2 is arranged in the middle of the two flanges 1. The flange 1 and the multi-channel corrugated pipes are connected by threads. A sealing gasket 3 is arranged between the channel bellows, a sealing ring 4 is arranged between the flange 1 and the inner pipe connector 2 , and the two flanges 1 and the inner pipe connector 2 are fixed by screws 5 . the

The connector described in the utility model is connected according to the following steps:

A. Clean up the end of the multi-channel corrugated pipe to be connected, and apply an appropriate amount of glue on its surface, place a gasket 3 on the end, and then quickly screw on a connecting flange 1 and tighten it;

B. Repeat step A to connect another multi-channel bellows with another flange 1;

C. Place the two sealing rings 4 on both sides of the inner tube connector 2 respectively, and then insert one end of the communication hole 22 of the inner tube connector 2 into the inner tube of a multi-channel bellows that has been connected to the flange 1 , insert the other end of the communication hole 22 of the inner pipe connector 2 into another inner pipe of the multi-channel corrugated pipe that has been connected with the flange 1;

D. Use screws 5 to connect the two flanges 1 and the inner pipe connector 2 together. the
