本系列鐘形卸灰閥廣泛適用于冶金、建材、石化、電力等行業，作為各工業爐窯及除塵系統的卸灰裝置。
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.
結構特點：
Structure characteristic:
該鐘形卸灰閥由閥體、錐形閥塞、連桿、驅動裝置等組成，用連桿拉動閥塞上下運動完成啟閉動作。其中X型為橡膠軟密封，應用于冶煉高爐噴煤系統的煤粉輸送控制。W型為閥體本體材料密封，應用于除塵系統塵灰輸送控制。
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:
手動鐘形卸灰閥利用力矩平衡的方法實現卸灰。當作用于錐形塞上的物料產生的力矩大于重錘搖桿產生的力矩時，錐形塞打開向下卸灰。一旦積灰卸去后，重錘與搖桿產生的力矩使錐形塞迅速關閥。落料的頻率及卸灰量依據工況需要來調整重錘位置。
執行機構得到程序指令后推動搖桿使錐形塞打開向下卸灰，積灰卸去后，依據程序規定時間，推桿推進使錐形塞關閉密閉。執行機構的推出與推進都有行程控制，同時反饋開關信號。
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.
