Installation And Maintenance Of Butterfly Valves
1. During installation, the valve disc should stop in the closed position.
2. The opening position should be determined according to the rotation angle of the butterfly plate.
3. For butterfly valves with a bypass valve, the bypass valve should be opened before opening.
4. Installation should be carried out according to the manufacturer's installation instructions. Butterfly valves with heavy weight should be installed on a solid foundation.
Working Principle
The butterfly valve is a valve that opens and closes by rotating the valve stem while driving the disc to rotate. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, mainly rotating the disc 90° for flow control. , when the disc reaches 90°, the valve is in a fully open state. At the same time, the angle of the disc can be changed to adjust the medium flow. It is generally installed in the diameter direction of the pipe. The butterfly valve and the valve stem themselves have no locking ability. In order to effectively adjust the flow rate, a worm gear reducer is required. A butterfly valve equipped with a worm gear reducer not only makes the butterfly valve self-locking, but also changes the operating performance of the butterfly valve and regulates the medium flow rate more accurately. .
Features Of Butterfly Valve
(1) Simple structure and small external dimensions. Due to its compact structure, short structural length, small size and light weight, it is suitable for large diameters. (1) Simple structure and small external dimensions. Due to its compact structure, short structural length, small size and light weight, it is suitable for large diameters. (3) It is easy to open and close quickly, has good adjustment performance, and the butterfly plate rotates 90 degrees. Both opening and closing can be completed. By changing the rotation angle of the butterfly plate, the flow rate can be controlled in stages. (4) The opening and closing torque is small. Since the butterfly plates on both sides of the rotating shaft are basically equally affected by the medium, and the torque is generated in opposite directions, opening and closing is less labor-intensive. (5) The low-pressure sealing performance is good. The sealing surface materials are generally made of rubber and plastic, so the sealing performance is good. Limited by the material of the sealing ring, the operating pressure and operating temperature range of the butterfly valve is small. However, the operating pressure and operating temperature range of hard-sealed butterfly valves have been greatly improved.
Main Performance Features
1. Unique structure, small and light, flexible operation, labor-saving and convenient;
2. The sealing is reliable and can achieve air sealing without leakage;
3. The flow characteristics tend to be linear with the best adjustment performance;
4. Using the three-eccentricity principle, the sealing surface has nearly zero wear and extends the service life of the valve;
5. Wide range of applications. For example: it can be used for water, steam, oil, air, gas and other media.
6. It is suitable for pipelines with different temperatures and pressure levels below 6.4MPa, and is resistant to corrosion and other media.
