Product Description
1. Structural Features
- Wafer - type Connection: This valve is designed with a wafer - type connection, which is installed between two pipeline flanges and tightened by bolts. The compact structure takes up minimal space, making it highly suitable for applications where space is limited.
- Worm Gear and Worm Drive Mechanism: The worm gear and worm drive system offers high transmission efficiency and requires a small operating torque. It enables precise control over the valve's opening degree, allowing for a smooth 90° rotation for opening and closing operations.
- Double - Eccentric Design: Thanks to the double - eccentric design, the valve achieves a self - tightening sealing function during the closing process. As the valve closes, the sealing performance becomes more reliable, ensuring effective prevention of media leakage.
2. Materials
- Valve Body: Commonly used materials for the valve body include WCB carbon steel, QT450 - 10 ductile iron, and HT200 gray cast iron. These materials endow the valve body with high strength and good corrosion resistance, enabling it to adapt to various working environments and media.
- Butterfly Disc: The butterfly disc is usually made of WCB carbon steel, QT450 - 10 ductile iron, or HT200 gray cast iron. For special requirements, stainless steel and other special materials can also be selected to ensure the strength and corrosion resistance of the disc.
- Valve Shaft: The valve shaft is typically made of 2Cr13 stainless steel, which has excellent corrosion resistance and wear resistance. This ensures that the valve shaft is not easily damaged during long - term use.
- Sealing Ring: High - quality oil - resistant rubber and other materials are used for the sealing ring. It has good elasticity and sealing performance, guaranteeing the sealing effect of the valve and extending its service life.
3. Sealing Performance
- Soft Sealing Materials: Equipped with high - performance soft sealing materials such as nitrile butadiene rubber (NBR) and ethylene propylene diene monomer rubber (EPDM), the valve provides excellent sealing performance, achieving zero leakage or minimal leakage.
- Special Sealing Structure: With a special sealing structure design, such as the double - eccentric or triple - eccentric structure, when the valve is closed, the butterfly disc can fit closely with the sealing ring. This effectively prevents the leakage of media, ensuring reliable operation under different working conditions.
4. Working Pressure and Temperature
- Working Pressure: The general working pressure of this valve is 1.6MPa. However, products with different pressure ratings, such as 1.0MPa and 2.5MPa, can also be provided according to customers' needs to meet various engineering requirements.
- Applicable Temperature Range: The applicable temperature range is usually from - 40°C to 90°C. If special materials like fluororubber sealing rings are used, the temperature range can be extended to - 20°C to 200°C, making it suitable for a wider variety of operating conditions.
5. Flow Characteristics
- The valve exhibits an approximately equal percentage flow characteristic. During the opening process of the valve, the flow rate gradually increases with the increase of the valve opening degree in a relatively uniform manner. This allows for precise control of the fluid flow, meeting the requirements of different technological processes for flow regulation.
6. Applicable Media
- It is suitable for a wide range of media, including water, air, natural gas, oil products, and weakly corrosive fluids. Different combinations of materials and sealing materials can be selected according to the specific characteristics and requirements of the media to ensure the proper operation of the valve.
7. Drive Mode
- Mainly Worm Gear Drive: The main drive mode is the worm gear and worm drive, where turning the worm gear drives the opening and closing of the butterfly disc. In addition, electric, pneumatic, or hydraulic actuators can be equipped as required to achieve remote control or automated operation, providing more flexibility in different application scenarios.
8. Installation and Maintenance
- Installation: The installation of this valve is not restricted by the flow direction of the media or the spatial position. It can be installed in any direction, which greatly simplifies the installation process and reduces installation difficulties.
- Maintenance: With a simple structure, the valve is easy to maintain. Regular inspection of the sealing performance of the valve and the working condition of the drive mechanism is required. In case of any damage, the corresponding components can be replaced in a timely manner to ensure the normal operation of the valve.
