The invention relates to a flow-limiting
revolving door. The flow-limiting
revolving door effectively solves the problem that a gate cannot limit the passing frequency. According to the technical scheme, the flow-limiting
revolving door comprises a rotating shaft of the gate, a shell parallel to the rotating shaft is fixed to the outer wall of the rotating shaft, the interior of the shell is divided into a first cavity, a second cavity and a third cavity from bottom to top, a
piston is installed in the third cavity, the rotating shaft rotates to enable the first cavity to suck liquid from the second cavity and then push the liquid in the first cavity into the third cavity, a first through hole is formed in the lower end of the third cavity, a fixed annular sleeve is coaxially arranged outside the rotating shaft, teeth are evenly distributed on the circumference of the inner wall of the annular sleeve, a clamping block penetrating through the side wall of the third cavity in the radial direction is installed on the third cavity, if the rotating shaft rotates too fast, the liquid can enter the third cavity too fast, the clamping block can be pushed outwards after the
piston moves upwards to exceed the highest position, and the outer end of the clamping block is inserted into the teeth of the annular sleeve; and according to the flow-limiting revolving door, the passing frequency of the gate can be limited, and people in places in the gate can be prevented from being gathered and disordered.
