本申请公开了一种卸灰阀及其排料和密封的控制方法，该卸灰阀包括阀体和安装在阀体上部的料仓；阀体和料仓的连接口设有阀芯，阀芯转轴上设有扭矩传感器；由计算机系统对卸灰阀进行精准控制。控制时，利用扭矩传感器实时采集扭矩值，判断确定出的料仓的当前装料量与目标排料量之间的关系，准确确定料仓是否需要排料，以控制卸灰阀进行定量、精准的排料。同时，将料仓的当前剩余料量与卸灰阀密封所需目标料量进行对比，以准确判断当前卸灰阀是否满足密封条件，以强化密封效果。可见，利用扭矩传感器实时采集扭矩值，来判断料仓是否需要排料以及卸灰阀是否满足密封效果，控制过程简便、准确，通过准确控制卸灰阀进行定量排料，避免能耗过高的问题。

The application discloses an ash discharge valve and a control method for discharging and sealing thereof. The ash discharge valve comprises a valve body and a silo installed on the upper part of the valve body; The connecting port between the valve body and the silo is provided with a valve core, and the rotating shaft of the valve core is provided with a torque sensor; The ash unloading valve is accurately controlled by the computer system. During control, the torque sensor is used to collect the torque value in real time, judge the relationship between the determined current loading amount of the silo and the target discharge amount, and accurately determine whether the silo needs discharge, so as to control the ash discharge valve for quantitative and accurate discharge. At the same time, the current remaining material quantity of the silo is compared with the target material quantity required for the sealing of the ash discharge valve, so as to accurately judge whether the current ash discharge valve meets the sealing conditions and strengthen the sealing effect. It can be seen that the torque sensor is used to collect the torque value in real time to judge whether the silo needs to discharge and whether the ash discharge valve meets the sealing effect. The control process is simple and accurate. The ash discharge valve is accurately controlled for quantitative discharge to avoid the problem of high energy consumption.
