Reducing gear drives cam rotate to top half-turn and link gear of upper gate move, top disc opens and discharges. Spring device makes disc close and replace with displacement of cam. When cam rotates to bottom half-turn link, gear of sub-layer gate moves, below disc opens and discharges. The disc closes little by little with the displacement of cam. These two actions maintain a closed state of either disc on the pipe. So it can discharges and lock air at the same time.?

减速装置带动凸轮旋转至上半圈时，上层阀门的连杆机构互动，阀板逐渐打开卸灰，随着凸轮的旋转，弹簧机构使阀板逐渐关闭复位；凸轮旋转至下半圈时，下层阀门的连杆机构互动，阀板逐渐打开卸灰，随着凸轮的旋转又使阀板逐渐关闭，这样两个动作使管道上阀板始终有一个是关闭状态，因而，可使卸灰与锁气同时达到目的。
