Safety valve model issue
Thread Content
The model of the safety valve indicated on the drawing is A412F—10—15T. The way in which safety valve models are designated, as I’ve found, isn’t like this. Are 1 and 2 both related to the structural type? What does 15T mean? Could anyone who knows please explain it to me?
I’ll answer it myself. A—safety valve; 4—flange connection; 12—the spring is located below the valve seat and is in frequent contact with the medium; F—fluoroplastic; 10—nominal pressure of 1.0 MPa; 15T—fifteenth design iteration? Is the explanation for 15T correct? I would appreciate guidance from experts
T should represent a core made of copper. 15 doesn’t know what it represents.
Just the core? In the valve model coding method I found, T stands for copper and copper alloys. In HG3157 \"Spring-type safety valves for liquefied petroleum gas tankers\", the last element in the model coding indicates the number of design iterations. The Baidu-based valve model coding method cannot explain that type of safety valve, so I didn’t dare to use T to represent the material
This code is likely the manufacturer’s own code; you can ask the manufacturer. I’ve encountered this before; it’s the manufacturer’s own code, where T indicates that the core is made of copper.
