具体实施方式
以下结合附图和具体实施方式来进一步说明本发明。
如图1-图6所示，本发明公开一种旋转式变频切换阀，其工作介质为压缩空气，包括 阀体1、转动设置于所述阀体1内与所述阀体1相配合的阀芯2、驱动所述阀芯2转动的伺服电 机3，所述阀体1上沿其轴向开设有与所述阀芯2相配合的阀芯腔，所述阀芯2上沿其径向开 设有穿孔6，所述阀体1的两侧沿其径向分别开设有介质入孔7以及主介质出孔8，所述介质 入孔7与所述主介质出孔8分别与所述阀芯腔相连通，所述介质入孔7、所述主介质出孔8以 及所述穿孔6的中心位于同一水平面； 所述阀体1的阀芯腔的孔壁上开设有若干环形储气槽4以及至少两个环形密封槽5，若 干所述环形储气槽4均与沿着所述阀体1轴向开设的轴向通道9相连通，所述轴向通道9与所 述介质入孔7相连通，所述环形储气槽4、所述环形密封槽5沿着所述阀体1的轴向分布，若干 所述环形储气槽4位于两个所述环形密封槽5之间，所述环形密封槽5内设置有环形密封圈； 所述穿孔6内固定设置有与其同心设置的环形气囊18，所述环形气囊18的中部具有供 介质穿过的贯穿孔，所述阀芯2上开设有与所述环形气囊18相连通的进气通道以及排气通 道，所述轴向通道9的一端为盲孔，所述轴向通道9的另一端连接有储气罐17，所述轴向通道 9与所述储气罐17之间通过压力阀相连接，所述进气通道与所述储气罐17相连通，所述阀体 1上开设有排气孔，所述排气通道与所述排气孔相连通，所述排气孔处以及所述进气通道与 所述储气罐17的连接处均设置有单向电磁阀，所述介质入孔7处设置有用于检测介质流量 大小的流量检测计，所述流量检测计与两个所述单向电磁阀的控制器相连接。
工作原理：伺服电机3驱动阀芯2转动，当介质入孔7、穿孔6以及主介质出孔8三者对准时，压缩空气介质从介质入孔7穿过穿孔6从主介质出孔8排出，由于采用伺服电机3驱动阀芯2转动，继而阀芯2的转速可变频控制，使用方便，而且在阀体1上开设环形储气槽4，介质入孔7内的部分压缩空气通过轴向通道9进入环形储气槽4内，继而形成润滑气膜，用于阀芯2与阀体1之间的润滑，继而无需采用润滑油进行润滑，而且避免了在阀体1上开设油路，避免润滑油的泄露问题，而且采用压缩空气自润滑，润滑效果好，适用于高速旋转切换的切换阀； 流量调节过程：当流量检测计检测到介质入孔7处的介质流量较大时，排气通道的单向 电磁气阀打开通过排气孔进行排气，环形气囊18内的压缩气体排入储气罐17内，继而环形 气囊18体积变小，继而贯穿孔的面积变大，适用于大流量的介质通过；当流量检测计检测到 介质入孔7处的介质流量较小时，进气通道的单向电磁气阀打开，储气罐17内的压缩气体向 环形气囊18内充气，继而环形气囊18的体积变大，继而贯穿孔的面积变小，适用于小流量的 介质通过，而储气罐17内的压缩气体无需另外补充，直接由通过的压缩气体介质进行补充。
为了满足不同的使用需求，所述主介质出孔8的上下两侧分别开设有从介质出孔11，所述阀体1上开设有与两个所述从介质出孔11相连通的轴向连接腔10，所述轴向连接腔10与所述主介质出孔8相连通，使用者可以采用两个从介质出孔11以及主介质出孔8使用压缩空气，当不需要使用从介质出孔11时，只需将其封堵即可。
为了方便加工以及提高密封效果，所述环形储气槽4与所述轴向通道9之间通过沿着所述阀体1径向延伸的连接孔12相连通，所述连接孔12以及所述轴向连接腔10均为盲孔，所述连接孔12以及所述轴向连接腔10的一端均由密封堵头13密封。
为了能够将阀芯2进行限位的同时，对阀芯腔进行有效密封，所述阀芯2的两端与所述阀体1之间设置有用于限位密封的端盖14，所述端盖14由弹性卡扣15固定，所述阀芯2上开设有用于安装所述弹性卡扣15的安装槽，而且通过弹性卡扣15的方式对端盖14进行固定，不仅使用方便，而且方便加工。为了方便连接，所述伺服电机3的电机轴与所述阀芯2之间通过连接端子相固定连 接，所述阀体1的上下两端部均开设有安装腔，所述连接端子位于所述阀体1上部的安装腔 内，所述阀芯2下部的端盖14位于所述阀体1下部的安装腔内。
为了使得在启动前阀芯2四周与阀体1的阀芯腔之间保证合适间隙，保证阀芯2与阀体1之间的平衡，减少摩擦，所述阀芯2的表面开设有两道环形定位槽，所述环形定位槽位于所述环形密封槽5的外侧，所述环形定位槽内设置有由聚四氟乙烯制成的支撑环16。
为了提高使用寿命，所述阀体1与所述阀芯2两者的接触面具有耐磨防腐层，所述阀体1的阀芯腔孔壁具有磷化层，所述阀芯2的表面具有氮化钛处理层。
为了方便连接以及快速安装，所述介质入孔7、所述主介质出孔8以及所述从介质出孔11内均设置有快速接头。
