The icon in CAD for a check valve?
Thread Content
How to represent a check valve icon in CAD? Please help.
I’m also a beginner learning CAD; these methods are for reference only. For check valves, I think it’s sufficient to use the fill command to create a triangular area on top of the drawn ordinary gate valve; I don’t find it very complicated. As for the CAD icon you mentioned, haha, I didn’t notice it. . .
It has the shape of a capital Z, with a diagonal line and an arrow in the middle; it complies with GB20519-2009 – you can take a look. Our company encrypts documents, so you won’t be able to view them. Otherwise, I can just send them to you directly.
A Z reversed, plus the flow direction
There are two ways to represent a check valve: one is as an inverted Z shape with a small arrow, and it is called a check valve； One type is in an inverted Z shape, with an arrow added above or below the inverted Z; this is called a swing valve. It seems that the two types of check valves are used within different pressure ranges
