Brief description of wafer type butterfly valve:
A type of valve with a disc shaped butterfly valve opening and closing component that can rotate around the axis of the valve body. The wafer butterfly valve mainly consists of a valve body, valve stem, butterfly plate, and sealing ring. The valve body is cylindrical, with a short axial length and a built-in butterfly plate. The butterfly plate is driven by the valve stem, and if it is turned over 90 °, it can be opened and closed once. By changing the deflection angle of the butterfly plate, the flow rate of the medium can be controlled. Operating Conditions and Media: Wafer type butterfly valves are suitable for pipelines conveying various corrosive and non corrosive fluid media in engineering systems such as generators, gas, natural gas, liquefied petroleum gas, urban gas, hot and cold air, chemical smelting, power generation, environmental protection, building water supply and drainage, and are used to regulate and cut off the flow of media.
Application of wafer type butterfly valve:
Wafer type butterfly valves are applicable to systems and pipelines in petroleum, chemical, food, medicine, papermaking, hydropower, shipbuilding, water supply and drainage, smelting, energy, and other systems. They can be used as regulating and intercepting equipment on a variety of corrosive, non corrosive gas, liquid, semi fluid, and solid powder pipes and containers.
Performance characteristics of wafer type butterfly valves:
1. The clamp type butterfly valve has a simple and compact structure, light weight, and is easy to install, disassemble, and maintain.
2. The operating torque is small, and it is easy and fast to open and close when turning 90 °.
3. Small flow resistance, approximate inclined straight flow characteristics, and good energy-saving effect.
4. The butterfly valve has reliable sealing, zero leakage, and long service life.
5. It can be made of various materials and is suitable for various media.
6. The flow characteristics tend to be straight, with good regulation performance.
7. The butterfly valve has been tested tens of thousands of times and has a long service life.
Features of wafer butterfly valves:
The wafer type butterfly valve adopts a wafer center plate structure, mainly composed of the valve body, valve plate, valve shaft, valve seat, and transmission device. The structure is simple and compact, small and lightweight, and convenient for transportation, installation, and disassembly; 90 ° opening and closing, quick opening and closing, low operating torque, labor-saving and lightweight; Good sealing performance, long service life, and zero leakage; Its flow characteristics are approximate to a straight line, with good regulation performance.
Sealing performance of wafer butterfly valve:
The wafer type butterfly valve is rubber sealed, and when closed, the butterfly plate and valve seat have good sealing performance. The bidirectional sealing performance is excellent, and the torque value is small. The valve maintains 100% zero leakage under working pressure, and the friction between the butterfly plate and valve seat seal is small. The valve is driven by the valve shaft and the valve plate rotates 90 °. The butterfly plate is flexible in opening and closing, without jamming or jumping, and has low torque.
