[0002] The tertiary air valve is a device used to adjust the tertiary air volume, and plays an important role in the new dry kiln. The tertiary air valves currently used mainly include gate valves and butterfly valves. The gate valve changes the ventilation area by adjusting the insertion depth of the valve plate, and only a part of its valve plate is located in the tertiary air duct, and the scouring is less than that of the butterfly valve. However, due to the harsh working environment, the life of the gate valve plate is still short. Generally, the valve plate needs to be replaced if it is used for no more than 8 months in a cement plant.

[0003] An adjusting nut is often welded on the upper end of the valve plate of an existing gate valve. The adjusting nut is directly threadedly connected to the adjusting screw. The adjusting screw is rotated to drive the adjusting nut to move the valve plate up and down in the gate body to change the ventilation area. However, this structure is not convenient for replacing the valve plate. The entire gate valve can only be dismantled and replaced with a new one, which is costly. Summary of the invention
