The Work Process and how to use manual butterfly valve
A butterfly valve is a flow control device used to regulate or isolate fluid flow in a pipeline. It operates using a disc, which rotates on a shaft to open or close the flow passage. Here’s a concise guide on its work process and usage:
Work Process:
1. Design and Structure:
– The butterfly valve consists of a circular disc (the “butterfly”) that is mounted on a rotating shaft.
– The disc is positioned in the center of the pipe and connected to an actuator or handle.
2. Operation:
– Open Position: When the handle is turned, the disc rotates 90 degrees to align with the flow direction, minimizing resistance and allowing full flow.
– Closed Position: Rotating the disc 90 degrees perpendicular to the flow stops fluid movement entirely.
– Throttle Position: Intermediate positions of the disc regulate flow rates.
3. Sealing:
– The disc forms a seal against the valve seat, preventing leakage. Seals can be soft or hard depending on the application.
Using a Manual Butterfly Valve:
1. Inspection:
– Check for any signs of damage or obstructions in the valve and surrounding pipe.
2. Installation:
– Ensure the valve is properly aligned with the pipe flanges and securely bolted.
– The handle should be positioned for easy access.
3. Operation:
– To Open: Turn the handle counterclockwise until the disc is fully aligned with the pipe.
– To Close: Turn the handle clockwise until the disc is perpendicular to the flow.
– To Throttle: Adjust the handle to a position between fully open and fully closed to control the flow rate.
4. Maintenance:
– Periodically check the valve for leaks or wear.
– Lubricate moving parts as needed and replace seals if they are worn.
Applications:
Butterfly valves are used in various industries such as water distribution, chemical processing, and HVAC systems due to their simplicity, durability, and quick operation.
Understanding and following these steps ensures efficient and safe use of manual butterfly valves in fluid control systems.
