What weight should the transition flange used to connect a 10-kilogram valve to a 0.6-kilogram valve have?
Thread Content
The one above is a valve flange of 10 kilograms, the one below is a valve flange of 0.6 kilograms; what weight should the connecting flange in the middle have?
A size head should be installed, one end being 0.6 and the other 0.1
The leader gave me a rough diagram – just a flange that is symmetrical in all directions – and told me to figure it out on my own. I’m confused about the transition from 10 kilograms to 0.6
It’s relatively rare; it’s better to fabricate it oneself using non-standard methods
One is 10 kilograms and the other is 0.6
First, you need to consider the flange standard being used. In HG/T20592-2009, the connection dimensions for flanges at 1.0MPa and 0.6MPa are the same; I’m not aware of any other standards that follow this rule. If the connection dimensions for flanges at 1.0MPa and 0.6MPa are identical, then the flanges to be used can be determined. If they differ, then use flanges rated at 1.0MPa for the upper part and those rated at 0.6MPa for the lower part
They can’t be connected if the pressures are different; a short coupling can be used, one that handles 10 kilograms of pressure on one side and 6 kilograms of pressure on the other.
