Network optimization information:
Butterfly valve, also known as flap valve, is a control valve with a simple structure, which can be used for switching control on low-pressure pipeline media. A butterfly valve is a valve that rotates around the valve shaft in a disc-shaped form (valve or butterfly plate) to open or close. It can be used to control various fluids, such as air, water, steam, various corrosive media, mud, oil, Liquid metal and radioactive media, etc. Cut off and throttle the pipeline. The shutter of the butterfly valve is a disc-shaped butterfly plate. In the butterfly valve body of the two-position two-way solenoid valve, the butterfly valve can rotate around its own axis to realize opening and closing or adjustment.
The selection principle of electric butterfly valve.
Rod diameter: For multi-stage rotating rising stem valves, they cannot be assembled into electric valves. Therefore, if the maximum stem diameter allowed by the electric butterfly valve device cannot pass through the valve stem of the equipped valve, the inner diameter of the hollow output shaft of the electric device must be greater than the outer diameter of the valve stem. For the five-position three-way solenoid valve partial rotary valve and the dark-stem valve in the multi-stage rotary valve, although there is no need to consider the passage of the stem diameter, the stem diameter and the size of the keyway should also be fully considered when selecting and matching. It can work normally after assembly.
