What are the main parts of the double flange electric ball valve? The Dongfeng double flange electric ball valve is composed of loose flange expansion joints, short pipe flanges, valve screws and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate for pipeline installation errors. The double flange electric ball valve cannot absorb axial displacement. Dongfeng experts explained to us in detail what are the main parts of the double flange electric ball valve and what are the materials of each part, so that we can have a deeper understanding of the double flange electric ball valve.
Double flange valve connection is mainly used for loose sleeve connection of pump, valve and other accessories. The double flange loose sleeve electric ball valve is composed of loose sleeve expansion joint, short pipe flange, valve screw and other components. It can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, and cannot absorb the axial displacement. It is important for loose sleeve connection of pump, valve, pipeline and other accessories. Nominal diameter: DN50mm-DN3200mm Working pressure: 0.6-1.6MPA
Medium used: water, sewage. Sealing material: NBR manufacturing standard: GB12465-2002. Applicable scope of double flange electric ball valve: This product is suitable for conveying sea water, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and granular powder with temperature not higher than 250 degrees.
1 Body 1QT450-10, Q235A2 seal ring 1NBR3 gland 1QT450-10, Q235A4 stub flange 1Q235A5 bolt nQ235A, 35 # 6 nut Tn Q235A, 20 # double flange electric ball valve is easy to install, convenient for valve installation, and can withstand the axial tension of the pipeline. The product is made of metal casting or welding. Trapezoidal valve sealing ring is selected for loose sleeve part under the action of gland and bolt.
Utilize the principle of valve compression elastic deformation. Force the seal ring to deform between the outer wall of the expansion pipe of the joint body for static sealing. Metal and sealing ring shall be selected in strict accordance with service performance and user requirements. The exterior of the material is coated with high-strength anti-corrosion paint, and the connecting bolts of each part are made of high-strength carbon steel or stainless steel. Because there is a certain gap between the body and the expansion tube, it has a certain axial and radial displacement. It can effectively compensate and relieve the thrust of pipeline and blind plate in the pipeline, and also facilitate the installation, maintenance and replacement of pumps and valves. It is actually the most ideal supporting product in the pipeline installation and operation industry.
