Product Description
I. Product Definition and Principle
The manual wafer - type butterfly valve is a valve that manually operates the handle to drive the valve stem to rotate, enabling the disc to make a 90° rotation inside the valve body, thus achieving the opening, closing, and flow regulation of the valve. It adopts a wafer - type connection method and is installed between two pipeline flanges.
II. Product Features
- Lightweight Structure: Compact in structure, small in size, and light in weight, making it easy to handle and install. It saves space and reduces labor intensity and installation costs.
- Convenient Operation: With a small operating torque, it controls the disc by rotating the valve stem through the handle. It is labor - saving and flexible, and can quickly complete the opening and closing actions.
- Flexible Installation: Not restricted by the flow direction of the medium, it can be installed in any position, suitable for various complex pipeline layouts.
- Reliable Sealing: There are various sealing material options, and the seals can be replaced. It has good sealing performance, and some can achieve zero leakage in both directions.
- Easy Maintenance: Simple in structure with few vulnerable parts inside, resulting in low maintenance difficulty and cost.
III. Technical Parameters
- Nominal Diameter: Commonly ranges from DN40 to DN2000, meeting the requirements of pipelines with different diameters.
- Nominal Pressure: Such as 0.6MPa, 1.0MPa, 1.6MPa, etc., depending on working conditions and materials.
- Applicable Temperature: Depends on the materials of the valve body and seals. For example, rubber seals are generally suitable for - 40ºC - 90ºC; fluororubber seals can reach - 20ºC - 200ºC; polytetrafluoroethylene seals are suitable for around - 30ºC - 150ºC.
- Test Pressure:
- Strength Test: For example, when the nominal pressure is 0.6MPa, the strength test pressure is 0.9MPa; when it is 1.0MPa, the strength test pressure is 1.5MPa, etc.
- Sealing Test: For example, when the nominal pressure is 0.6MPa, the sealing test pressure is 0.66MPa; when it is 1.0MPa, the sealing test pressure is 1.1MPa, etc.
- Air - tightness Test: Generally 0.6MPa.
- Applicable Media: Air, water, sewage, steam, gas, oil products, etc. Some special materials can be used for corrosive media.
IV. Main Parts Materials
- Valve Body: Cast iron, ductile iron, cast steel, alloy steel, stainless steel, UPVC, CPVC, PP, etc.
- Disc: Cast steel, stainless steel, special materials, or coated with rubber, etc.
- Valve Stem: 2Cr13, stainless steel, etc.
- Sealing Ring: Various rubbers (neoprene rubber, nitrile rubber, EPDM rubber, fluororubber, etc.), polytetrafluoroethylene (PTFE), EPDM, etc.
- Packing: O - rings, flexible graphite, etc.
V. Execution Standards
- Manufacturing Standard: GB/T 12238 - 1989, etc.
- Flange Standard: GB/T9113.1 - 2000, GB/T9115.1 - 2000, JB78, etc.
- Face - to - Face Dimension Standard: GB12221 - 89.
- Inspection Standard: GB/T 13927 - 1992.
VI. Application Fields
- Water Supply and Drainage Systems: In building and municipal water supply and drainage, it controls the flow and cut - off of water.
- Industrial Pipelines: In industries such as chemical engineering, petroleum, power, metallurgy, food, and pharmaceuticals, it regulates or intercepts gas, liquid, and semi - fluid media.
- HVAC Systems: It regulates the flow of air and water, such as in the pipelines of fan - coil units and air - handling units.
- Environmental Protection Projects: In sewage treatment and waste gas treatment facilities, it controls the flow of media.
VII. Installation and Maintenance Key Points
- Installation: Place it between two pipeline flanges, align the bolt holes, insert bolts, and tighten them. Ensure the correct installation direction (although some butterfly valves are not restricted by the medium flow direction, there may be specific requirements). After installation, check the flexibility of the disc opening and closing and the smooth operation of the handle.
- Maintenance: Regularly check the sealing performance for any leakage. Check the connection parts of the handle and valve stem to ensure no looseness. Clean the surface and interior of the valve from impurities in a timely manner. Replace aging seals regularly.
