Dear Masters, shouldn’t double gaskets be added to the flange of the safety valve?

Dear Masters, shouldn’t double gaskets be added to the flange of the safety valve? Are there any relevant standards for this? Thanks
It makes people suspect that the valve is short or the reserved position of the pipeline is too long.
It looks like it's a single-head bolt, so the pressure shouldn't be high. This is illegal and should be corrected
Hello, which standard specification contains this relevant requirement? I searched for a long time but couldn't find it
People who do this simply don’t understand how gaskets work, and the middle part will inevitably leak.
I've never heard of adding 2 spacers.
