Dalian marine shut-off valve is an equipment used in ship pipelines, mainly to control the flow of media, and can be used for the transmission of liquids, gases, or vapors. There are several installation methods for Dalian marine valves:

1. Flat installation

Flat installation is one of the common installation methods for marine globe valves. Install the shut-off valve parallel to the pipeline and fix it by connecting it with the pipeline. During installation, it is important to ensure that the opening and closing direction of the shut-off valve is consistent with the direction of the pipeline to ensure smooth flow of the medium.

2. Vertical installation

Vertical installation refers to installing the globe valve vertically on the pipeline. This installation method is relatively flexible and can adapt to the installation needs of different positions and angles. During the installation process, it is important to note that the pipes connected to the shut-off valve must be horizontal or vertical to ensure the normal flow of the medium.

3. Flange installation

Flange installation is the process of connecting a shut-off valve to a pipeline through a flange. Compared with other installation methods, flange installation has the characteristics of convenient interface, easy disassembly and maintenance. Attention should be paid to the flange connection method during installation to ensure reliable sealing of the connection.

4. Welding installation

Welding installation is the process of fixing a shut-off valve onto a pipeline by welding. This installation method is sturdy and suitable for the transmission of high-pressure, high-temperature, or corrosive media. During installation, attention should be paid to the temperature during welding and the quality of the weld seam after welding to ensure the stability and sealing of the pipeline.

5. Installation of pressure stop valve

This type of valve is used as a boiler feedwater and steam shut-off valve, and it has a comprehensive function of a lifting globe valve and a globe or angle valve.

In short, different installation methods are suitable for different occasions, and during the installation process, attention should be paid to factors such as connection method, direction, sealing, and corrosion prevention. Only by correctly installing marine shut-off valves can the normal operation of pipelines be ensured, providing guarantees for the safe operation of ships.
