Further, during installation, if the valve core 21 is installed from outside to inside, the limiting protrusion 312 will interfere with the sealing joint 32, so that the valve core 21 cannot rub against the end surface of the valve core 31 during up-and-down movement, thereby facilitating adjustment of the valve core 21 and improving stability of the safety valve.

Referring to fig. 8 and 9, therefore, in this embodiment, the adjusting assembly further includes a snap ring 34 and a sealing joint 32, the sealing joint 32 is mounted at the mounting hole, an annular abutment protrusion 313 is disposed at an end of the rotating shaft 31 away from the housing 10, the rotating shaft 31 is inserted into the sealing joint 32 from inside to outside, the snap ring 34 is clamped on the rotating shaft 31 and is located between the abutment protrusion 313 and the sealing joint 32, after the rotating shaft 31 is plugged into the sealing joint 32, the snap ring 34 is clamped between the abutment protrusion 313 and the sealing joint 32, and when the rotating shaft 31 needs to be disassembled, the snap ring 34 is removed, and then the rotating shaft 31 is pushed inwards, thereby facilitating the installation and the disassembly of the rotating shaft 31.
