具体实施方式
下面结合附图对本发明创造实施方案进行详细描述。一种喷洒药液快速泄压与分路同压控制阀，在阀体23内设置进液腔24、喷液腔20、泄压腔21和调压腔25，所述进液腔 24分别与喷液腔20和调压腔25连通，所述喷液腔20与泄压腔21连通；喷头19固装在阀体23下侧部上，且与喷液腔20连通；在所述阀体23上端外侧部上安装箱体27，安装板1、上限位开关7和下限位开关8固装在箱体27内，电机3固装在安装板1上，双联中间齿轮 4和螺纹轴6可转动的安装在安装板1上，在所述电机3和螺纹轴6上分别固装主动齿轮 2和驱动齿轮5，所述主动齿轮2与双联中间齿轮4啮合，双联中间齿轮4与驱动齿轮5啮合；主轴9可上下轴向移动的插配在阀体23内，在所述主轴9上端部上、位于箱体27内部固装限位杆26，所述限位杆26与上、下限位开关7、8呈接触或脱离接触配合；在所述主轴9 上从上至下依次可轴向滑动的套装上锥阀12、中锥阀13和下锥阀14，所述上锥阀12和中锥阀13位于进液腔24内，上锥阀12与进液腔24和调压腔25连通阀孔呈接触密闭配合，中锥阀13与进液腔24和喷液腔20连通阀孔呈接触密闭配合，所述下锥阀14位于泄压腔 21内，且与喷液腔20和泄压腔21连通阀孔呈接触密闭配合，上卡簧15、中卡簧17和下卡簧22从上至下依次固装在主轴9上，所述上卡簧15位于上锥阀12上方，中卡簧17位于中锥阀13下方，下卡簧22位于下锥阀14上方，上压力力弹簧16套装在主轴9上，所述上压力弹簧16的上、下端分别与上锥阀12和中锥阀13接触配合，在所述泄压腔21内、位于下锥阀14下侧配装下压力弹簧18，所述下压力弹簧18下端在泄压腔21上轴向定位，下压力弹簧18上端与下锥阀14接触配合；在所述调压腔25上可轴向移动的配装调压阀杆10，所述调压阀杆10与调压腔25的进液孔呈插入密闭配合或脱离插入配合，在调压阀杆10外端部上配装调压旋钮11。
作业使用时，带有压力的药液充入进液腔24内，经中锥阀13下方的进液腔24与喷液腔20之间的连通阀孔进入到喷液腔20内从喷头19喷出，完成药液喷洒作业。停止喷洒作业时，电机3的旋转运动经主动齿轮2、双联中间齿轮4、驱动齿轮5驱动螺纹轴6转动，并将主轴9向下方移动，在上卡簧15推动下，使上锥阀12随主轴9同步下移，打开进液腔 24与调压腔25之间的连通阀孔，同时在上压力弹簧16作用下，中锥阀13随主轴9下移，并将进液腔24与喷液腔20之间的连通阀孔封闭，下卡簧22随主轴9向下移动时推动下锥阀 14向下移动，打开喷液腔20与泄压腔21之间的连通阀孔，存留在喷液腔20内的压力药液从泄压腔21排回到药液箱内，避免从喷头19处泄漏或产生后滴现象。限位杆26与下限位开关8接触，使电机3停止转动，限制了主轴9的下极点位置。将几个本控制阀并联安装实现几行喷洒药液使用时，当将其中部份行数喷头19停止喷洒药液作业时，通过转动停止作业行的调压旋钮11，调节调压阀杆10与进液腔24和调压腔25之间连通阀孔的开启度，即可保证喷洒作业中的其他行喷头19的喷液压力，实现分路同压调节控制。
