Abstract

本发明涉及流体管道的磁控开关，它利用永磁体 的磁力来控制活塞开关，通过管道中流体的自身压力 来推动活塞启闭，为人们提供一种无机械外通，全密 封，无泄漏、免维修、省力、快速、易制造，造价低的新 型阀门。可以生产磁控阀的系列换代产品。

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阀和龙头，目前阀的种类很多，其控制开关的方式，都采用机械外通式的开关及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未有采用永磁力控制的。
本发明是在我们发明的CN86209051磁控水龙头，CN87105761磁控阀的基础上更进一步完善，由于前二项发明只能在小通径管道上使用，本发明取消了上述二项发明中的内磁衔铁顶杆（针）从而使工艺更简单，适用范围更广，制造特大通径的阀门能在低压、中压、高压的情况下使用。
本发明的任务，是提供一种在结构上无机械外通，全密封;在操作上不费力，速度快;在使用上无磨损，免维修的新型流体管道的磁控开关装置。
本发明的特点在于：它利用永磁体的磁力作用实现全密封的开关控制，免去机械外通式的开关结构，因而无外漏，无磨损;它用外磁环（块）和内磁顶（连顶杆），代替转盘螺杆、缩小了结构体积，减少了加工难度，省去了变速系统以及密封填料，因而降低了成本;它用活塞代替阀瓣、使启闭力与流体压力相一致，因而无内漏，无压坏机件，并能大幅度地节省启闭动力;它用直线运动的把头代替螺旋运动的转盘，因而开关行程短、启闭速度快、操作简便，并适用于自动化控制。
下面的附图对本发明的实施例作进一步描述：（一）图一是本发明截止型的小阀和水龙头的结构示意图，如图一所示：
图中是关闭位置，当打开时，将装有外磁环（6）的把头（7）往上提起;外磁环（6）的吸力吸着在密封活动套（3）内的内磁顶（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）的强压比正压区（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）提升得越高，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）内磁顶（5）向下运动，使活塞（2）上的卸压孔（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。
（二）图二是本发明截止型大阀的结构示意图，如图二所示;
图中是关闭位置，它是在小阀的基础上多加一级或两级大活塞，这时的小活塞（14）为大活塞（15）卸压孔的顶塞，其工作原理与小型阀完全一样。弹簧（13）是为了阀在横装或倒装，并且管道中无压力时而设的。
（三）图三是本发明蝶型磁控阀的结构示意图，如图三所示;
图中为关闭位置，当打开时，将装有磁块（18）的旋把（29）向逆时针方向转动，外磁块（18）吸力吸着在密封活动盘套（20）内的内磁块（19）带动连顶杆（17）向逆时针转动，使阀板（22）上的卸压孔（24）打开，随即负压孔（25）关闭，阀板（22）内腔的负压区（26）的流体便从卸压孔（24）中排出，由于阀板（22）边上的胀圈槽（28）通过腔槽通孔（23）相连通，这时内腔负压区（26）的压强小于正压区的压强，故装在胀圈槽（28）内的胀圈（27）受到正负压力差的影响而松小，此时阀板（22）与阀座（21）内壁已无摩擦作用，而连顶杆（17）继续带动阀板（22）向逆时针转动，从而打开阀座通道（21）。
当关闭时，将旋把（29）向顺时针转动，内磁块（19）受到外磁块（18）的吸力而带动连顶杆（17）向顺时针转动，使阀板（22）上的负压孔（25）打开，随即关闭卸压孔（24）连顶（17）继续带动阀板（22）向顺时针转动，当将近达到关闭时，流体通过阀板（22）上的负压孔（25）在阀板（22）内腔的负压区（26）形筛貉梗ü徊弁祝?3）直接作用在胀圈（27）上，使其澎胀，从而达到关闭阀座通道（21）。
对于特大通径的蝶型磁控阀，可在内磁块（19）和连顶杆（17）之间加入蜗轮蜗杆作减速传动，以缩小永磁体的体积和达到操作上的更省力。
