Detailed Description

the technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.

Referring to fig. 1-3, a regulating valve for a ventilator, the regulating valve 1 is installed in the ventilator and used for controlling the air intake of the ventilator; the adjusting valve 1 comprises a main shaft 12, an air plate 11, an adjusting tooth structure 13 and an adjustable push rod structure 14, wherein the two ends of the main shaft 12 are installed on the wall of a ventilator pipe, the air plate 11 is sleeved on the main shaft 12 and rotates around the main shaft 12 to control the air inlet quantity, the adjusting tooth structure 13 is installed in the middle of the main shaft, and the adjustable push rod structure 14 is in rotating fit with the adjusting tooth structure 13 to push the air plate 11 and fix the position of the rotated air plate 11; the adjustable push rod structure 14 comprises a driving cavity 141 connected with the wind plate 11 and covering the adjusting tooth structure 13, a hollow push rod 142 arranged on the driving cavity 141, and an adjusting ball 143 and a spring 144 arranged in the hollow push rod 142, wherein the spring 144 is arranged in the hollow push rod 142 and is adjustably connected with the adjusting tooth structure 13 through the adjusting ball 143, so that a ventilation adjusting fixing structure which pushes the hollow push rod 142 around the main shaft 12 to change the connecting position of the adjusting tooth structure 13 and the adjusting ball 143 and adjusts the opening size of the wind plate 11 is formed. The regulating tooth structure 13 is a half gear. The regulating tooth structure 13 arranged in the middle of the main shaft 12 is also arranged in the middle of the wind plate 11.

The main shaft 12 is square so as to be detachably and fixedly connected with the wall of the ventilator tube, and the sleeve rotating hole of the wind plate 11 is also square. The main shaft 12 is provided with a rotating support shaft 121 for sleeving the air plate 11, and the air plate 11 rotates along the rotating support shaft 121.
