Hot-blast stove heat supply regulator elastic limiting device

The invention provides a hot-blast stove heat supply regulator elastic limiting device, and relates to the technical field of hot-blast stoves. The hot-blast stove heat supply regulator elastic limiting device comprises a segment of rectangular air channel which is internally provided with an air shielding plate. The two sides of the air shielding plate are installed on the side wall of the rectangular air channel via rotating shafts. The rotating shaft of one side of the air shielding plate penetrates through the side wall of the rectangular air channel to be connected with a revolving handle. The internal side of the revolving handle is provided with a locking device. One side wall provided with the rotating shaft is provided with multiple positioning grooves which are evenly distributed on the semicircular tracks with the rotating shaft acting as the center. The side surface of the air shielding plate is provided with elastic limiting devices matched with the positioning grooves. Quantity of hot-blast air can be regulated. Hot-blast air regulation possesses multiple gears. Each gear is accurately positioned by the positioning grooves. The air shielding plate can be accurately regulated. After the air shielding plate is well regulated, the air shielding plate can be locked by the locking device so that rotation of the air shielding plate caused by the effect of air flow can be avoided.
