AI Technical Summary
Existing gas grid pressure regulating devices require the removal of the protective casing to adjust the pressure regulating rod, which makes operation inconvenient.
A gas grid pressure regulating device was designed. By setting a through groove on the protective shell, the pressure regulating rod can be extended and rotated directly from the outside of the protective shell. Combined with the extension rod and the rotating ring structure, the rotation adjustment of the pressure regulating rod can be realized, avoiding the need to disassemble the protective shell.
It allows for direct adjustment of the pressure regulating lever without removing the protective shell. The protective shell serves both a protective function and a pressure regulating function, making operation more convenient.
