How to properly install and maintain Chinese butterfly valves? Practical guide
China’s butterfly valve is a common fluid control equipment, widely used in petroleum, chemical, metallurgy, electric power and other industries in the pipeline system. The correct installation and maintenance of Chinese butterfly valves is essential to ensure the normal operation and extend the service life of the equipment. This article will provide you with a practical guide on how to properly install and maintain Chinese butterfly valves from a professional perspective.
First, the preparatory work before installing the Chinese butterfly valve
1. Confirm the valve type and specifications: Before purchasing Chinese butterfly valves, you need to confirm the required valve type (such as flange, sandwich, etc.) and specifications (such as DN50, DN80, etc.).
2. Check the valve material: according to the nature of the medium in the pipeline, choose the appropriate valve material, such as carbon steel, stainless steel, alloy steel, etc.
3. Prepare the installation tools: During the installation, prepare some common installation tools, such as wrenches, screwdrivers, and torque wrenches.
4. Clean the pipe: Before installing the Chinese butterfly valve, please ensure that the inside of the pipe is clean and free of impurities, so that the valve can be better sealed.
Second, the installation steps of China butterfly valve
1. Determine the valve location: According to your piping system design, choose a suitable location to install the Chinese butterfly valve. Generally, the Chinese butterfly valve should be installed on the horizontal pipe, and the distance from the ground is high, so as to facilitate operation and maintenance.
2. Mark the valve installation position: Use a pencil or other marking tool to mark the valve position on the pipe to ensure that it will not be misaligned during installation.
3. Install the support: according to the weight and size of the valve, choose the appropriate support to support the valve. The bracket shall be installed at the bottom of the pipe, perpendicular to the valve.
4. Install the valve: Connect the Chinese butterfly valve with the support, and fix the valve on the support using bolts. During installation, make sure the valve is closed to prevent media leakage.
5. Connect the power and control signal: If the Chinese butterfly valve needs remote control or automatic control, you also need to connect it with the corresponding power and control signal.
Third, the maintenance and maintenance of Chinese butterfly valve
1. Regular inspection: In order to ensure the normal operation of the Chinese butterfly valve, you should check it regularly. Check the sealing performance of the valve, operating torque, bearing wear and so on.
2. Clean the valve: During use, dust and impurities may accumulate. To ensure the sealing performance of the valve, you should regularly clean the valve surface and seals.
3. Lubricate bearings: For Chinese butterfly valves with bearings, you need to lubricate their bearings regularly. The choice of lubricant should be determined according to the use of the valve environment and the nature of the medium.
4. Replace the damaged parts: If a part of the Chinese butterfly valve is found to be damaged or seriously worn, it should be replaced in time. This helps to extend the service life of the valve and reduce safety hazards.
5. Follow the operating procedures: When using the Chinese butterfly valve, please strictly follow the operating procedures to avoid overload operation or using inappropriate tools to operate the valve.
With the above practical guide on how to properly install and maintain Chinese butterfly valves, you can ensure the proper operation of your equipment and extend its service life. Please note that different types of Chinese butterfly valves may require different installation and maintenance methods, so in actual operation, be sure to refer to the relevant product instructions.
