Description

低功耗电动阀门
技术领域
[0001 ] 本发明涉及一种水利管道流通阀门,特别是涉及一种低功耗电动阀门。
背景技术
[0002] 给排水工程采用电动阀门来控制管道的供水与断水。管道的供水与断水由电动阀门中的排水活门启闭决定。排水活门的启闭由压力控制腔内的流体压力决定,压力控制腔内的流体压力是由电动执行器的球形开关或者柱形开关改变控制管路截面来改变流体流量和压力建立的。传统电动阀普遍采用球形开关或者柱形开关的结构形式,电动阀门中,表面设有密封橡胶体的球形或者柱形开关其体积需随电动阀门进出水管管径大小而定,电动阀门管径大、流量大,带有橡胶密封体的球形开关或者柱形开关则大,其摩擦力以及开、关门力也大,耗电量也高;反之,球形或者柱形开关光洁度高,摩擦力以及开、关门力就小,耗电量也小。电动阀门的体积或质量对节能降耗关系密切。传统电动阀门有以下弊端:一、球形开关或者柱形开关开、关门力大,耗电量高。二、排水活门结构复杂,金属构件多,制造成本高。三、排水活门的金属件以及电动执行器的球形或者柱形开关等关键零件长期浸于水中工作,表面易锈蚀结垢、光洁度下降,故障率高。球形或者柱形开关表面锈蚀结垢会造成开、关门力增大,耗电量更加增大,还会因为开关光洁度下降造成控制管路中的来水与出水流体相互渗漏串通,使排水活门下面进水腔压力与排水活门上部压力控制腔的压力压差失准,排水活门工作失灵;排水活门的金属构件锈蚀结垢,会造成阀芯卡死电动阀门无法正常工作。四、排水活门进水腔与出水腔之间的密封效果差,进水腔与出水腔密闭不严,使电动阀门工作性能不稳,供水管路关闭失准。综上所述,开发一种既经济又可靠的新结构形式,解决电动阀门耗能问题,提升扩大电动阀门的应用范围是亟待解决的问题。
发明内容
[0003] 本发明的目的是要克服传统电动阀门的缺陷,给出一种电动阀门中排水活门的结构简单、金属构件少、生产制作成本低、电动阀门管径与排水量大耗电量却低、节省电能源,关键构件不易锈蚀故障率低,密封性好,工作性能稳定的低功耗电动阀门。
[0004] 本发明的目的是能够实现的。本发明的低功耗电动阀门包括固接成一体的阀体、阀盖、电动执行器以及电器护罩和接线盒,其中阀体左端设有进水腔,右端设有出水腔,进水腔与出水腔通过控制阀芯或者关断或者打开,压力控制腔与进压导流孔和泄压导流孔连通,其特征在于:所述阀体与阀盖之间固定连接一个盆状的整体式橡胶密封阀芯,阀盖与整体式橡胶密封阀芯之间形成压力控制腔,所述整体式橡胶密封阀芯通过底部下表面周边缘的凸起与阀体的进水口以及安装在进水口上的阀座贴合连接,通过底部中心处的螺纹孔螺纹连接流通活门的螺杆,所述流通活门通过自身的导向爪滑动安装在阀座上,导向爪之间的间距构成水流通道,流通活门螺杆中心设有进压导流孔,进压导流孔与进水腔和压力控制腔连通,所述整体式橡胶密封阀芯底部上表面设有弹簧,弹簧上部套接在阀盖下面的弹簧座上,所述阀盖于弹簧座中心处设有一个呈三阶梯通孔的开关工作腔,所述开关工作腔的小直径孔与中直径孔结合部形成的台阶上设有密封胶圈,上部大直径孔为螺纹孔,密封胶圈的上面设有一个大陶瓷圆片开关,所述大陶瓷圆片开关被连接在阀盖螺纹孔上的桶状定位套的桶壁压接在密封胶圈上面,所述定位套的桶腔内部下面设有一个与大陶瓷圆片开关上表面贴合连接的小陶瓷圆片开关,所述大陶瓷圆片开关和小陶瓷圆片开关在相同直径的直径线两端各对称的设有两个相互沟通且形状相同的开关导流孔,所述定位套的桶壁上部设有一个与所述泄压导流孔连通的连通孔,所述小陶瓷圆片开关上面连接转动轴,转动轴穿过桶状定位套及密封圈与电动执行器连接,所述开关导流孔下面与压力控制腔连通,上面通过桶状定位套桶壁的连通孔与泄压导流孔连通。
