Installation and Debugging Method of Chinese Flange Connected Middle Line Butterfly Valve

This article provides a detailed introduction to the installation and debugging methods of Chinese flange connected midline butterfly valves, including preparation work, installation steps, debugging process, and precautions. The aim is to help readers correctly install and debug midline butterfly valves and ensure their normal operation.

1、 Introduction

The Chinese flange connected midline butterfly valve is a commonly used industrial valve with the advantages of simple structure, convenient operation, and wide flow adjustment range. In industrial pipeline systems, the correct installation and debugging of centerline butterfly valves is of great significance for ensuring stable system operation and reducing energy consumption. This article will provide a detailed introduction to the installation and debugging methods of Chinese flange connected midline butterfly valves.

2、 Preparation work

1. Familiarize yourself with valve drawings and parameters: Before starting installation, you should have a detailed understanding of the structure, dimensions, and performance parameters of the valve to ensure that the selected valve meets the actual working conditions.

2. Prepare installation tools: Based on the actual situation, prepare suitable installation tools such as wrenches, screwdrivers, hammers, etc.

3. Check valves and flanges: Check for damage, deformation, etc. to ensure that the dimensions of the valves and flanges match.

3、 Installation steps

1. Assembly of valve: Assemble the various components of the valve according to its structure, paying attention to the assembly sequence and bolt tightening torque.

2. Valve to flange connection: Connect the valve to the flange, pay attention to alignment, and ensure that the valve centerline coincides with the pipeline centerline. Tighten the bolts to the specified torque.

3. Install valve drive device: Install corresponding drive devices such as manual wheels, electric devices, etc. according to the valve drive method.

4. Pipeline connection: Connect the valve to the upstream and downstream pipelines to ensure good pipeline sealing.

4、 Debugging process

1. Manual operation: Manually operate the valve and check if the valve switch is smooth and there is no jamming.

2. Check the sealing performance of the valve: Through pressure testing, check the sealing performance of the valve to ensure that it does not leak under specified conditions.

3. Automatic control debugging: For electric valves, perform automatic control function debugging to ensure that the valve can automatically open and close under set conditions.

4. System joint debugging: Conduct joint debugging between the valve and other equipment and control systems to ensure the normal operation of the valve under actual working conditions.

5、 Precautions

During the installation process, follow the requirements of the valve installation manual to ensure installation quality.

During the debugging process, pay attention to safety and avoid accidents caused by improper operation.

3. Regularly check the operation of the valve and promptly handle any problems found.

4. Regularly maintain and maintain valves to extend their service life.

6、 Summary

The correct installation and debugging of Chinese flange connected midline butterfly valves is crucial for ensuring the stable operation of industrial pipeline systems. By familiarizing oneself with valve drawings, preparing installation tools, following the installation steps, and debugging valve performance, ensure that the valve operates normally under actual working conditions. At the same time, strengthen the maintenance and upkeep of valves to improve their service life.
