Gain a deep understanding of the working principle and maintenance methods of the butterfly valve on the middle line of the clamp in China

The butterfly valve in China is a common control valve widely used in the industrial field. Its working principle and maintenance methods are crucial for ensuring the normal operation of the equipment. This article will provide an in-depth analysis of the working principle and maintenance methods of the butterfly valve in China.

1、 Working principle

The Chinese wafer center line butterfly valve mainly consists of valve body, valve plate, bearings, and seals. When the valve is closed, a closed sealing environment is formed between the valve plate and the valve seat; When the valve opens, the valve plate fully opens the valve seat with the rotation of the valve stem. The butterfly valve in China controls the opening and closing degree of the valve plate by rotating the valve stem, thereby regulating the flow of medium in the pipeline.

The advantage of China’s mid line butterfly valve lies in its simple and reliable structure, small size, light weight, fast opening and closing, and excellent flow control performance. Its sealing performance is stable and its service life is long.

2、 Maintenance methods

The correct maintenance method can extend the service life of the Chinese wafer centerline butterfly valve and ensure its stable operation. Here are some common maintenance methods:

1. Regular inspection: Regularly inspect the working status of the Chinese wafer center line butterfly valve, including whether the valve body, valve plate, sealing ring, and other parts are worn or aged. If there is wear or damage, replace it promptly.

2. Clean the valve body: Regularly clean the valve body and valve stem to ensure that their surfaces are clean and smooth. Use a soft cloth or brush to remove impurities and deposits from the valve body and stem.

3. Lubrication: China lubricates the bearings and valve stems of the center line butterfly valve, using appropriate lubricants to ensure smooth operation.

4. Sealing ring replacement: Regularly inspect the sealing ring of the valve, and if aging or wear is found, replace it in a timely manner. Ensure the sealing performance of the valve.

5. Pay attention to corrosion prevention: For Chinese wafer center line butterfly valves used in corrosive media, anti-corrosion measures such as coating and anti-corrosion treatment need to be taken to extend the service life of the valve.

6. Pay attention to antifreeze: In cold environments, corresponding measures need to be taken to prevent China from freezing and freezing the butterfly valve on the clamp line. Heating equipment or insulation measures can be used.

Different measures need to be taken according to the actual situation when maintaining the butterfly valve on the middle line of the clamp in China. At the same time, records and regular maintenance plans should be maintained to promptly identify and resolve issues.

In summary, it is important to understand the working principle and correct maintenance methods of China’s mid line butterfly valves. Regular maintenance and upkeep can ensure the normal operation of the valve and extend its service life, while reducing the possibility of malfunctions. When necessary, you can also refer to relevant technical manuals or consult professional personnel.
