Help needed with high-pressure container! In the calculation sheet derived from the design of SW6 high-voltage equipment, what does “y” refer to in the biconical ring seal?

This post was last edited by WallaceLee on 2020-11-4 at 15:13. I am currently using SW6 to design a high-voltage device; the shell structure chosen is a single-layer shell, and the head type used is a flat cover head. The flat cover type is as shown in the figure: The sealing surface used is a biconical ring seal. However, as shown in the figure, an issue arises when generating the calculation report: the value of “y” for the biconical ring seal is 0, which affects the subsequent calculations of the bolt preload and the total cross-sectional area of bolts required for tightening. My question now is: 1. What does “y” represent in the biconical ring seal? 2. Which item in the design parameter input corresponds to “y”? How is it entered in SW6? I seek advice from experts! ! !
It is recommended to learn about self-sealing and forced sealing
You can try entering a number; y should be the specific pressure.
Table 7-29 (continued) of GB/T150.3-2011: Specific pressure of metal plates
If you don’t enter a value, the software will assume it’s zero, I think; it’s better to enter the pressure applied by the gasket: lol
Seal specific pressure. It can be found in the gasket properties table on page 191 of GB/T150.
