A butterfly valve is a type of throttling valve that controls the flow of fluids or regulates flow through the rotation of a circular disc.
Its core structure includes:
Valve body: A symmetrical design that supports various connection types, including wafer, flange, and welded connections. Materials include cast iron, cast steel, stainless steel, and UPVC.
Valve stem: Connects the disc to the actuator and must be corrosion-resistant and high-strength to ensure long-term stable operation.
Disc: A circular, thin structure commonly made of stainless steel, copper alloy, or nylon. Hard alloys (such as STL alloy) can be overlaid on the surface for improved wear resistance.
Seals: These include the seat ring and O-ring, made of elastic materials such as EPDM and PTFE (soft seals) or metal-to-metal construction (hard seals) to prevent leakage.
Actuator: Supports manual, electric, pneumatic, or hydraulic operation to accommodate diverse operating conditions.
1. Regular Inspection
Appearance Inspection: Check the valve body for rust, paint peeling, deformation, and other conditions, and repair them promptly.
Connections: Check for loose bolts and stuffing box leaks to ensure tightness.
Openness Indicator: Verify that the valve opening is consistent with the control signal to prevent improper operation.
2. Lubrication and Cleaning
Transmission Components: Regularly lubricate the valve stem, bearings, and gears to reduce wear.
Valve Interior: Disassemble and clean the valve cavity, valve core, and sealing surfaces to prevent dirt accumulation.
3. Seal Maintenance
Seal Surface Inspection: Repair minor wear or scratches to restore sealing performance.
Seal Replacement: Regularly replace O-rings or valve seats based on usage.
Electric Actuator Maintenance
4. Power Supply and Line: Check voltage stability and line connection reliability.
Motor and Reducer: Monitor operating status and replace worn gears or bearings promptly.
Travel Limit and Torque Protection: Ensure valve operation within a safe range to prevent overload.
