Product Description
Structural Features
- Valve Body: Usually cast from materials such as ductile iron, which has high strength and good corrosion resistance. The wafer - type structure makes the valve body compact and it can be installed between two flanges, saving space.
- Disc: Generally made of metal, and its surface can be specially treated to enhance wear and corrosion resistance. It is in the shape of a disc and rotates around the valve shaft to achieve opening and closing actions.
- Seat: Elastic sealing materials such as rubber are often used, which can provide good sealing performance and prevent media leakage.
- Actuator: In the picture, it is a manual worm - gear drive. By rotating the handwheel, the disc is driven to rotate through the worm - gear transmission. In addition, there are also electric, pneumatic and other driving methods, which can realize automatic control.
Working Principle
It relies on the rotation of the disc around the valve shaft to control the opening and closing of the valve. When the disc is perpendicular to the pipeline axis, the valve is in the closed state, cutting off the flow of the medium; when the disc rotates to be parallel to the pipeline axis, the valve is opened, allowing the medium to pass through smoothly. When it is partially open, it can regulate the flow of the medium.
Application Fields
- Water Supply and Drainage Systems: Used to control the transportation and distribution of water, such as in urban water supply pipelines and sewage treatment plants.
- HVAC Systems: Regulate the flow of media in the air - conditioning water system and ventilation system to maintain the stability of system pressure and temperature.
- Industrial Fields: In the process pipelines of industries such as petrochemical, power, and metallurgy, it is used to cut off or regulate the flow of various corrosive and non - corrosive media.
Advantages
- Small Volume and Light Weight: Compared with gate valves, globe valves, etc., it is more convenient for installation and handling.
- Easy to Operate: When it is manually driven, just rotate the handwheel. When it is automatically driven, the control is simple.
- Low Flow Resistance: The pressure loss is small when the medium passes through, and it has a good energy - saving effect.
Limitations
- Relatively Limited Sealing Performance: In extreme working conditions such as high pressure and high vacuum, the sealing effect may not be ideal.
- Limited Adjustment Accuracy: For some occasions with extremely high requirements for flow adjustment accuracy, it may not fully meet the needs.
