Abstract

The invention discloses a throttling device with two-stage control, which comprises a left and right through installation pipe, two left and right interfaces are opened on the pipe wall of the installation pipe, and a connecting pipe is connected between the two interfaces. There are two throttle heads corresponding to the interface one by one. The outer wall of the throttle head is in sealing fit with the inner wall of the installation pipe. There are through holes evenly distributed on the cylinder wall of the throttle head. The two throttle heads The ends close to each other are closed, and a transverse rack is connected to the closed end of each throttle head. Two gear shafts arranged side by side are installed in the installation tube. The gear rack is meshed, and the upper end of each gear shaft extends out of the installation pipe and is connected with a driving device. The above structure controls the movement of the two throttling heads through the driving device, the gear shaft and the rack to realize the opening and closing of the two interfaces, thereby providing a two-stage regulating throttling device with high precision, simple structure, and easy production .

Description

technical field [0001] The invention belongs to the technical field of throttling devices, and in particular relates to a two-stage regulating throttling device. Background technique [0002] At present, the function of the throttle valve is to control the flow rate of the fluid and adjust the flow rate of the fluid, and is widely used to adjust the movement speed of the actuator. Existing ordinary throttle valves have the problem of inaccurate adjustment accuracy. For equipment with high precision requirements, imported high-precision throttle valves are often used, but these imported throttle valves have complex structures and high costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-precision, low-cost throttling device with two-stage regulation. [0004] The technical scheme of the present invention is as follows: a throttling device for two-stage control, including a left and right through installa...
