Abstract

本发明是一种流体管道的磁控开关。这是利用永磁体的磁力控制阀板内腔内磁块顶端的蝶型顶塞作开关，通过管道中流体的压力推动阀启闭。该磁控开关省磁材，易造，启闭快速，操作轻便，适用范围广，可以成为生产流体管道的磁控开关的系列换代产品。

Description

本发明是涉及流体管道的磁控开关，特别是各种类型大小通径的龙头。目前阀的种类很多，其控制开关的方式，都采用机械外通式开关，利用垫片和填料等配件，因此易磨损锈蚀、打滑、泄漏、操作费力，开关速度慢，常要维修，使用期短，造价高，已知的技术中，在流体管道阀的开关上，采用永磁力控制的阀和水龙头仍不理想，需改进与完善。
本发明是在原发明的CN86209051磁控水龙头和CN87105761磁控阀的基础上，更进一步的改进与完善，是用内磁块，取消了上述二项发明中只能在小通径管道上使用的内磁衔铁顶杆（针），外磁环替代磁环，加级活塞，将活塞改成空腔阀板形式，在阀板腔中内磁块顶端设蝶型阀等改进、本发明的目的是所提供的一种省磁材、能在特大通径管道上使用的流体管道的磁控开关。
本发明的特点在于：
1.用外磁环块和内磁块代替外磁环和内磁衔铁顶杆（针），节省磁材，缩小了结构体积，减少加工难度，降低了成本。
2.用加级活塞代替阀瓣，使启闭力和流体压力相一致，而成为大通径阀，能在低、中、高压下更广的范围作用；
3.活塞改成空腔阀板，在阀板腔中内磁块顶端设一蝶轴阀即为蝶型阀，使开关行程短、启闭速度快，操作轻便，适用于自动化控制。
本发明由下面给出的附图和实施例实现：
图1是本发明的截止型小阀和水龙头的结构示意图，图1中：1、阀座、2、活塞，3、密封活动套，4、负压孔（或间隙），5、内磁块（连顶杆），6、外磁环块，7、把头，8、定位圈，9、卸压孔，10、负压区，11、正压区，12、阀座通道；
图2是本发明加级活塞截止型大通径阀的结构示意图，图2中表示：是在图1的基础上加一或两级活塞，图2为加一级活塞，加级活塞14为原活塞卸压孔的顶塞，弹簧13是为阀的横装或倒装、管道中无压力时而设置；
图3是本发明将活塞改成空腔阀板，在阀板腔中内磁块顶端蝶型阀的结构示意图；
图4是图3的A－A面结构示意图，图3和图4表示：改成空腔阀板2，其内腔有：内磁块顶端的蝶型轴15，与蝶型轴连一体的另一头蝶型顶塞16，卸压孔9和负压孔4开在阀板两侧，阀板内腔槽通孔17，胀圈18，胀圈槽19。
本发明的实施例：
实施例1，如图1所示：图中是关闭位置，当打开时，将装有外磁环块6的把头7往上提起，外磁环块6的吸力吸着在密封活动套3内的内磁块5向上运动，使活塞2的卸压孔9打开，负压区10的流体便从卸压孔9中排出，这时，负压区10的压强比正压区11的压强小，于是活塞2受正压区11的推力而向上运动，阀座1的通道12随即打开，把头7提升得越，通道12就开得越大，流体的流量也就越大；当关闭时，按下把头7，内磁环块5向下运动，使活塞2的卸压孔9关闭，流体通过活塞2旁的负压孔（或间隙）4在负压区10形成负压，活塞2受到负压的推力和流体的流冲力而向下运动，直至关闭通道12，定位圈8是为控制流量定位和防止把头7越出密封活动套3而设置。
实施例2，如图所示：图中是关闭位置，即在图1的基础上，加一或两级活塞，加级活塞14为原活塞卸压孔的顶塞，弹簧13是为了阀的横装或倒装，管道中无压力时而设置，其工作原理同实施例1。
实施例3，如图3和图4所示：图中为关闭位置，当打开时，将装有外磁环块6的旋把7向逆时针方向转动，外磁环块6吸力吸着密封活动套3内的内磁块5带动顶端上的蝶型轴15连成一体的另 一头蝶型顶塞16也随着转动，使阀板2的卸压孔9打开，随即关闭负压孔4，阀板内腔的负压区10的流体便从卸压孔9中排出，由于阀板2边上的胀圈槽19与腔槽通孔17相连通，这时，阀板2内腔负压区10的压强小于正压区的压强，使装在胀圈槽19内的胀圈18受到正负压力差的影响而缩小，此时阀板2与阀座内壁已无摩擦作用，蝶型顶塞16继续带动阀板向逆时针转动，从而打开阀座通道12；当关闭时，将旋把7向顺时针转动，内磁块5受到外磁环块6的吸力，而带动其顶端上蝶型轴15及连着另一头蝶型顶塞16顺时针转动，使阀板的负压孔4打开，随即关闭卸孔9，蝶型顶塞16继续带动阀板向顺时针转动，将近于达到关闭时，流体通过阀板的负压孔4在阀板内腔的负压区10形成负压，通过腔槽通孔17直接作用在胀圈18上，使其膨胀，从而使阀座通道12关闭。
本发明对于特大通径的蝶型阀，可在内磁块和所述另一头蝶型顶塞16之间，加入蜗轮蜗杆作减速传动，以缩小永磁体的体积及达到操作上更省力。
