China butterfly valve installation and maintenance has always been only China butterfly valve manufacturers attach great importance to service projects, China's butterfly valve installation and maintenance related to the butterfly valve life and safety.


1. When the Chinese butterfly valve is installed, the valve flap must be stopped at the closed position.


2. The opening position should be determined according to the rotation angle of the butterfly plate.


3, with a bypass valve butterfly valve, open the bypass valve before opening.


4. China's butterfly valves should be installed in accordance with the manufacturer's installation instructions. China's heavy-duty butterfly valves should have a solid foundation.


5. The butterfly plate of the Chinese butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, the rotation angle is between 0° and 90°, and when the valve rotates to 90°, the valve is fully opened.


6. If the butterfly valve is required to be used as a flow control, the main thing is to correctly select the size and type of the valve. The structural principle of the butterfly valve is particularly suitable for making large-diameter valves. Butterfly valves are widely used not only in general industries such as petroleum, gas, chemical and water treatment, but also in cooling water systems of thermal power plants.


7. Commonly used Chinese butterfly valves have two kinds of clip-on butterfly valves and flange-type butterfly valves. The wafer type butterfly valve is connected with the valve between the two pipe flanges with stud bolts. The flange type butterfly valve is provided with a flange on the valve, and the upper flanges of the valve are connected on the pipe flange with bolts.


8. The butterfly plate of Chinese butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, the rotation angle is between 0° and 90°, and when the valve rotates to 90°, the valve is fully opened.
