Abstract

The invention discloses a throttling device of two-stage control. The throttling device comprises a transversely through installation pipe. The pipe wall of the installation pipe is provided with two interfaces at left and right. The two interfaces are connected through a connecting pipe. The installation pipe is provided internally with two throttling heads respectively corresponding to the interfaces. Outer walls of the throttling heads match the inner wall of the installation pipe in a sealing manner. Cylinder walls of the throttling heads are distributed uniformly with through holes. The adjacent ends of the two throttling heads are both closed. The closed end of each throttling head is connected with a transverse rack. The installation pipe is also provided internally with two gear shafts arranged side by side at left and right. The two gear shafts at the left and right are respectively engaged with the racks at the left and right. The upper end of each gear shaft extends out of the installation pipe to be connected with a drive device. The above structure achieves the opening and closing of the two interfaces by controlling the movement of the two throttling heads through the drive devices, the gear shafts and the racks, and therefore the throttling device of two-stage control is high in precision, simple in structure and easy to produce.
