Description

A radial deviation adjustment and compensation device for pressure pipeline installation

1. Technical field

The utility model relates to a new type of radial deviation adjustment and compensation device for pressure pipeline installation, which is mainly suitable for the installation process of pressure pipelines made of various metal materials.

2. Background technology

In current engineering applications, during the installation of pressure pipelines, especially during the installation of long-distance pressure pipelines, corrugated joints are often used for adjustment and compensation after radial deviations occur. However, the corrugated joints cannot deform greatly, otherwise it will cause them to bear pressure. The ability is greatly reduced or even damaged, so its applicability and usage functions are limited.

3. Contents of the invention

This utility model provides a new type of radial deviation adjustment and compensation device for pressure pipeline installation. The utility model is installed at both ends of butt pipes where large radial deviations occur. It has high safety and reliability, avoids deformation stress due to pipeline bending, and is easy to operate. specialty.

The technical solution adopted by this utility model to solve its technical problems is:

A pressure pipe installation radial deviation adjustment and compensation device, which is characterized in that the pressure pipe one and the male joint one are connected through pipe threads. After the male joint one and the female joint are adjusted in position, they are threaded through union one, and the connection part is passed through O-ring one is used for sealing; the other end of the female joint uses the same form. After adjusting the position, it is threaded with union two and male joint two. The connection part is sealed by O-ring two. Male joint two and pressure pipe two pass through Pipe thread connection.

The advantages of this utility model are that when connecting pipes with large radial deviations, pipe deformation and stress concentration are prevented; the overall structure is simple and the sealing is good; the connection form is simple, convenient to operate, and easy to install.

5. Specific implementation methods

Specific embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but are not intended to limit the scope of the present utility model.

As shown in Figure 1, the utility model has a pressure pipe installation radial deviation adjustment and compensation device, which is characterized in that: the pressure pipe one (1) and the male connector one (2) are connected through pipe threads, and the male connector one (2) After adjusting the position with the female joint (5), make a threaded connection through union one (3), and seal the connection part with O-ring one (4); use the same form at the other end of the female joint (5), and after adjusting the position The union 2 (7) is threaded with the male connector 2 (8), and the connection part is sealed with the O-ring 2 (6). The male connector 2 (8) is connected to the pressure pipe 2 (9) through pipe threads. .

The female connector (5) passes through the male connector one (2), union one (3), O-ring one (4), O-ring two (6), union two (7), and male connector two (8) They are connected to form the main body of the radial deviation adjustment and compensation device.

The working principle of the radial deviation adjustment and compensation device for pressure pipeline installation is described as follows:

After adjusting the position of the male joint one and the female joint, they are threaded through union one, and the connection part is sealed by O-ring one; the other end of the female joint uses the same form, and after adjusting the position, it is connected through union two and male joint two Threaded connection, the connecting part is sealed by O-ring two. At this time, the main body of the radial deviation adjustment and compensation device is completed; then the pipe thread sealing form is used through the male connector one and the male connector two to connect to the pressure pipe one and pressure pipe two respectively. The connection forms a closed pipeline and completes the radial deviation adjustment and compensation of the pressure pipeline installation.
