French A-shaped butterfly valve with aluminum handle manufacturers take you to understand the connection structure of flanged butterfly valve
French A-shaped butterfly valve with aluminum handle The manufacturer tells you that the flanged butterfly valve is connected by means of flanges, gaskets, bolts and other components. The installation and disassembly of this valve are very convenient, and its applicable nominal diameter and pressure The range is also wide. The flange connected to the valve can be divided into flat welding flange, butt welding flange, socket welding flange, integrated flange, etc. French A-shaped butterfly valve with aluminum handle manufacturers tell you that according to the form of sealing surface, it can be divided into full plane flange, boss flange, concave and convex flange, tongue and groove flange and ring groove flange.
Generally speaking, due to the low structural strength and rigidity, flat welding flanges are mostly used under mild operating conditions, such as low-pressure circulating water valves, general low-pressure compressed air valves, etc. Convenience. French A-shaped butterfly valve with aluminum handle manufacturers tell you that the neck and conical transition structure, strength and rigidity of the butt welding flange butterfly valve are good, and it can be connected to the pipe for non-destructive testing, so it is suitable for working conditions more severe occasions.
The French A-shaped butterfly valve with aluminum handle manufacturer tells you that the sealing surface of the valve is also selected according to its operating conditions. The full-plane structure is often used with the flat-welded structure. In the case of mild conditions, the boss surface is often used with the butt-welded structure. For use with socket welded structures. It is widely used, and the convex and concave surfaces are often used with butt welding and socket forms.
