本系列钟形卸灰阀广泛适用于冶金、建材、石化、电力等行业，作为各工业炉窑及除尘系统的卸灰装置。
This series valve is widely used in metallurgy, building material, oil chemical and electric power industries etc. It is the discharging device of stove and removing dust system.
结构特点：
Structure characteristic:
该钟形卸灰阀由阀体、锥形阀塞、连杆、驱动装置等组成，用连杆拉动阀塞上下运动完成启闭动作。其中X型为橡胶软密封，应用于冶炼高炉喷煤系统的煤粉输送控制。W型为阀体本体材料密封，应用于除尘系统尘灰输送控制。
This valve is made up of body, cone valve plug, connected pole, driving device etc. The plug drew by the connected pole moves up and down to complete the action of open and close. Type X denotes rubber soft seal, which is applied to carrying control of coal powder in smelt blast furnace gushing coal system. Type W denotes body material seal, which is applied to carrying control of dust powder in removing dust system.

工作原理：
Working principle:
手动钟形卸灰阀利用力矩平衡的方法实现卸灰。当作用于锥形塞上的物料产生的力矩大于重锤摇杆产生的力矩时，锥形塞打开向下卸灰。一旦积灰卸去后，重锤与摇杆产生的力矩使锥形塞迅速关阀。落料的频率及卸灰量依据工况需要来调整重锤位置。
执行机构得到程序指令后推动摇杆使锥形塞打开向下卸灰，积灰卸去后，依据程序规定时间，推杆推进使锥形塞关闭密闭。执行机构的推出与推进都有行程控制，同时反馈开关信号。
The valve realizes discharging using trimming moment. When the moment made by material on cone plug is greater than that of heavy hammer and rocker, the plug will open adown to discharge. After discharge the moment made by heavy hammer and rocker will drive cone plug close quickly. Dropping material frequency and discharge amount is determined by the working condition demａnd to adjust heavy hammer position.
Actuator drives the rocker after receives program order, and the rocker drives the plug open adown to discharge dust. Draw stem drives the plug to close according to the program time after discharge. Push and extrusion of actuator are controlled by journey and feed back switch signal at the same time.
