Parts of a Butterfly Valve
Valve Body: The main housing that encloses the internal components and provides a passageway for fluid flow.
Disc : A circular plate that rotates within the valve body to control the flow of fluid. When rotated, it opens or closes the valve.
Seat : A ring-shaped surface that the disc seals against when the valve is closed, preventing fluid leakage.
Stem: The connecting rod that attaches the disc to the actuator, allowing for manual or automated rotation of the disc.
Seals: Components that provide additional sealing between the moving parts of the valve, ensuring tightness and preventing fluid leakage.
How does a Butterfly Valve Work?
A butterfly valve works by rotating a circular disk (butterfly) within the valve body to control the flow of fluid. When the disk is rotated to align with the pipe, the valve is open, allowing fluid to pass through. Rotating the disk perpendicular to the pipe closes the valve, blocking fluid flow. This simple and effective design allows for quick and easy adjustment of fluid flow.
What is a Butterfly Valve Used for?
Butterfly valves are used where space is limited. Butterfly valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud,oil, liquid metal and radioactive media. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
Principle of Operation:The butterfly valve operates by rotating a circular disc within the valve body. When the disc is aligned with the flow, it allows fluid to pass; when perpendicular, it blocks the flow, providing precise flow control.
Where is the Butterfly Valve Located?
The butterfly valve is commonly located within a pipeline system, specifically at points where precise flow control, isolation, or shut-off of fluids is required. It is installed directly in the pipeline to regulate the passage of fluids through the system.
