What is a Butterfly valve?

It consists of a valve housing and a valve body. A flap having a rotatable disc shape or a double flat shape. Its function is to cut off the water flow. Its axis of rotation is perpendicular to the direction of water flow. When the valve body plane is in a state perpendicular to the water flow direction, the valve is closed. The butterfly valve has a rotatable disc or double flat valve. Suitable for large diameters and low heads. At present, the largest diameter has been used above 800cm, and the maximum head is 200 meters.

Butterfly Valve Main components

1.Valve ...
... body

The capacity is an aspect of the water section, through which the water streams, bolsters the heaviness of the valve, withstands the working power and force, and sends the water pressure.

2.The door

The effect is to cut off the water flow when it is closed. Requires sufficient strength. When it is opened, the hydraulic loss is small in the center of the water flow, and it has good hydraulic attributes.

3.Shaft and bearing

support the weight of the valve.

4.Locking ingots

The valve of the butterfly valve requires a lock ingot when it is fully closed or fully open.

5.Bypass valve and bypass pipe

Reduce the force when the main valve is opened, and eliminate the vibration under the moving water.

6.Air valve

When Stop, the air is supplied to the butterfly valve. Prevent the steel pipe from being damaged by the vacuum. Exhaust when the forward valve is opened and filled with water. The valve has a hollow float suspended below the pilot piston and the hollow float is on the surface of the volute or tube. Also, the vent is open to the atmosphere to vent or vent the volute and duct. When the pipe and the volute are filled with water, the pontoon floats to the limit position. The volute and the pipe are isolated from the atmosphere to prevent the water from overflowing.

7.Expansion joints

Simple to introduce and update, the steel pipe has space for development and withdrawal when the temperature changes.
