本技术涉及一种转换阀,属于阀门
技术介绍
水的硬度主要由其中的阳离子钙、镁离子构成,原水为未经处理的水,水的硬度大,其水中所溶的矿物质成分多,尤其是钙和镁,硬水在洗涤过程会降低洗涤效率,故原水一般可用于拖地等与人体不接触的场合;软化水是将水中的钙、镁盐通过软化机的树脂层吸附,同时释放出钠离子,这样软化机流出的水就是去掉了硬度离子的软化水,可用于洗澡、洗衣、洗菜等接触人体皮肤的场合。为了满足不同场合对原水和软化水的需求,故在管道上安装转换阀,公告号为CN203770733U的专利文献公开了一种转换阀,如图1和图2所示,其阀体1设有球阀座2、球阀芯3、阀柄4,球阀芯通过球阀座安装在阀体内,球阀芯为由通孔5和盲孔6组成的T形孔,初始阀柄处于关闭状态,转动阀柄,原水进水口通过球阀芯的通孔连通原水出水口,原水管路连通可提供原水,再次转动阀柄,原水通过原水进水口进入到通孔、盲孔然后通过软水入水口进入到软水机中软化水,软化水在经过软水回水口,通过原水出水口供应软水。该转换阀存在一个问题,供应原水时,由于球阀芯为T型三通球阀,为了保证球阀的转动空间,球阀芯与 ...
