所述电磁线圈 76还电连接一路磁场控制器, 磁场控制器安装在防护壳 77内。
所述空心阀体 74为空心管式的空心轴, 空心阀体 74伸入压气壳 71 内的部分的表面制 造成为光滑的圆柱面, 圆柱面与应磁活塞 72的中心圆孔配合; 空心阀体 74的下端制造有出 气密封端, 出气密封端的下端面制造在空心阀体 74的下端、 上端面制造成为内锥面, 内锥面 的大端与管轴式出气阀的上端相通、 小端与管轴式出气阀的下端相通, 在内锥面上安装有密 封锥 75。
应磁活塞 72制造成为圆柱形的铁芯, 圆柱形的铁芯的中心线的部位制造有光滑的中心 圆孔, 圆柱形的铁芯的外圆面制造成为光滑的外圆面; 在光滑的中心圆孔内制造有凹陷的环 槽, 环槽内嵌有密封环; 在光滑的外圆面上制造有凹陷的环槽, 环槽内嵌有密封环; 中心圆 孔与空心阀体 74的圆柱面配合而能够密封圆柱面, 并能够在空心阀体 74的圆柱面上滑动; 外圆面与压气壳 71的内腔配合能够密封压气壳 71的内腔,并能够在压气壳 71的内腔内滑动。
本发明的原理是: 磁场控制器接通电磁线圈 76 的通电电路产生电磁场, 电磁场产生的 吸引力拉动应磁活塞 72克服动力弹簧 73的压力向下移动, 此时, 进气阀门 710在自身重力 的作用下关闭进气通道, 应磁活塞 72下行时压缩压气壳 1内的空气而使空气产生内部压力, 有压力的空气从空心阀体 74 的下端进入出气密封端的内锥面向上冲开与出气密封端的内锥 面密封的密封锥 75移位后继续上行, 从空心阀体 74的上端进入通气管道 5输送到空气喷头 2处进行涂料涂覆作业。
以上所述, 仅是本发明的较佳实施例而已, 并非对本发明作任何形式上的限制, 虽然本 发明已以较佳实施例揭露如上, 然而并非用以限定本发明, 任何熟悉本专业的技术人员, 在 不脱离本发明技术方案范围内, 当可利用上述揭示的技术内容作出些许更动或修饰为等同变 化的等效实施例, 但凡是未脱离本发明技术方案的内容, 依据本发明的技术实质对以上实施 例所作的任何简单修改、 等同变化与修饰, 均仍属于本发明技术方案的范围内。
