When the to-be-regulated member is the valve clack 500 of the check valve, a protruding portion 520 is arranged on one side, away from the sealing surface 510, of the body of the valve clack 500 of the check valve, and when the valve clack 500 of the check valve is mounted on the first mounting plate 120, the protruding portion 520 penetrates through the mounting hole 121 and is partially arranged between the first mounting plate 120 and the support plate 110.

In some embodiments, the adjusting device further comprises a detecting member for detecting whether the member to be adjusted is in a horizontal state. Specifically, the detecting piece is a level bar, the level bar is placed on the piece to be adjusted, and the level bar can display the deviation degree of the piece to be adjusted and the horizontal position in the current state. When the piece to be regulated is a valve clack, the level ruler can display the deviation degree of the sealing surface and the horizontal position in the current state only by placing the level ruler on the sealing surface of the valve clack.
