The utility model relates to a voltage limiting valve definite value adjustment tool of center trompil, voltage limiting valve include the tube -shape casing and set up the first spring in the tube -shape casing and adjust the adjustment mechanism of the pressure of first spring, and the end edge that the one end opening of adjustment mechanism and tube -shape casing corresponds is equipped with the slot. Adjustment tool is including adjusting the pole. The one end of adjusting the pole is equipped with the U -shaped head, and the opening of U -shaped head deviates from the other end setting of adjusting the pole, and just the slot with adjustment mechanism corresponds to in inserting the slot of establishing adjustment mechanism edge in the voltage limiting valve, drive adjustment mechanism and rotate. Adjustment tool passes the central trompil and slot cooperation of tube -shape casing, rotates the pressure adjustment that adjustment mechanism realized first spring to realize the voltage limiting pressure t
