Sealing with pressure is a kind of sealing and sealing that is often used in pipes, containers and other equipment. Its main principle is to use pressure to contact the sealing object with the sealing surface to form a sealing effect. In practice, pressure sealing technology has a wide range of applications, such as petrochemical, shipbuilding, building energy and other fields.

First of all, understanding the basic principle of pressure plugging is the key to understanding its installation technology. In the process of plugging with pressure, it is necessary to select the appropriate plugging object, such as plugging ball, plugging plate, plugging agent, etc. These sealing objects need to have characteristics such as pressure resistance and corrosion resistance to ensure the reliability of the sealing fruit. At the same time, sealing with pressure also needs to provide a certain pressure source, such as liquid, gas, etc., to generate enough pressure to closely fit the sealing object and the sealing surface.

Comprehensive preparation is required before a pressure plug installation can be performed. First, clean and check the blocked area to ensure that the surface is smooth and free of impurities, and determine the size and location of the blocked object. Secondly, select the appropriate blocking object, and inspect and test it to ensure that its quality and performance meet the requirements. At the same time, prepare the required tools and equipment, such as plugging tools, pressure pumps, and sealants.

During the actual installation, select an appropriate installation method based on the actual situation. Common pressure sealing installation methods include the following:

1. Gas blocking: After the blocking object is injected into the pipeline or container through the air source to reach the pressure, the blocking object forms close contact with the sealing surface to achieve the blocking effect.

2. Liquid sealing: the sealing object is injected into the pipeline or container through the liquid medium, and the pressure of the liquid is pushed to the sealing position to form a sealing effect.

3. Installing the sealing plate: Place the sealing plate in the position to be blocked and secure it in place using bolts or other fixing devices. Before fixing the sealing plate, it is necessary to install the sealant or sealing gasket to ensure the sealing effect.

4. Sealing ball installation: The sealing ball is injected into the pipeline or container through the air source or liquid medium. After reaching a certain pressure, the sealing ball expands and fills the internal space of the pipeline or container to achieve the sealing effect.

After the installation is complete, you need to test and check the sealing effect. The reliability of the sealing effect can be judged by detecting the pressure change and leakage in the sealing area. If a problem is found, it needs to be adjusted and repaired in time to ensure the success of the installation.

In summary, the installation technology with pressure plugging is a complex and heavy work, which requires a full understanding of the principle and method of pressure plugging, and combined with the actual situation to choose the appropriate blocking object and installation method. Through good preparation and strict installation process, you can ensure the installation effect and stability of the pressure plug.
