Are safety valves installed both before and after the safety valve of the gas pressure regulating equipment? Is this in compliance with the **standards**? It seems nothing was found? ?

Does having safety valves at both the front and back of the gas pressure regulation equipment comply with **standards**? It seems nothing was found? ? Looking at old posts, it is generally said that since the front end can be removed for inspection, valves and seals can be installed there; but can valves be installed at the outlet release port? ? ? ? Can’t find any specific regulatory requirements specified by GB standards or safety standards? ? ?
GB50160，GB15O
