D341X Worm gear flange soft-seal butterfly valve
Structure and Materials The worm gear transmission core is continued. The worm is made of 20CrMnTi and carburized and quenched (hardness HRC58-62). The worm gear is selected from tin bronze ZCuSn10Pb1 (small diameter) or ductile iron QT500-7 (large diameter). The tooth surface is precisely ground, and the meshing accuracy reaches grade 7 of GB/T 10089. Ensure there is no jamming in the transmission. The transmission ratio is designed to match the diameter.
Worm gear driven flange-type butterfly valve
Structural composition It is composed of a high-precision worm gear (input end, connected to the handwheel or drive shaft) and a worm gear (output end, rigidly connected to the valve stem). Both are made of high-strength alloy materials (the worm gear is mostly 20CrMnTi and carburized and quenched, and the worm gear is tin bronze ZCuSn10Pb1 or ductile iron QT500-7), and the tooth surface is precisely ground.
D342X Double-eccentric soft-seal flange butterfly valve
The double eccentric soft-sealed flanged butterfly valve D342X is a high-performance valve product, widely used in various industrial pipeline systems.
Manual wafer-type butterfly valve
Manual wafer butterfly valves, as a common fluid control device, play a crucial role in industrial pipeline systems. Its structural design is compact.
DN2500 Flanged butterfly valve
The valve body is made by thick-walled integral casting process, using high-strength ductile iron QT500-7 (suitable for general industrial and municipal water supply) or carbon steel WCB (capable of withstanding higher pressure and non-corrosive media). For some parts used in highly corrosive environments, stainless steel 316L is welded into shape. The wall thickness is increased by 40% to 50% compared to the conventional diameter based on the pressure rating (such as PN10, PN16).
The valve body is made by thick-walled integral casting (ductile iron QT450-10, carbon steel WCB) or welding (stainless steel 304/316L). The wall thickness is increased by 20%-30% according to the pressure grade (such as PN10/PN16/PN25) (compared with DN1200), and the structure is optimized through stress analysis. Avoid valve body deformation caused by medium pressure under large diameters;
DN1200 Flanged butterfly valve
The valve body is formed by integral casting or welding (mostly made of ductile iron, carbon steel or stainless steel), and the wall thickness is designed according to the pipeline pressure grade (such as PN10/PN16) to ensure the pressure-bearing strength under the large diameter of DN1200 and avoid deformation.
large diameter center plate flange butterfly valve
Large-diameter center plate flanged butterfly valves play a crucial role in industrial pipeline systems. This type of valve, with its unique structural design, is particularly suitable for places that require large flow control and medium shut-off.
Connection method: The U-shaped flange butterfly valve DN1200 adopts flange connection and is directly connected to the pipe flange through bolts. This connection method ensures reliable sealing and convenient installation, making it particularly suitable for high-pressure and large-diameter scenarios.
