本发明全关闭位软水控制阀的工作原理：
工作位
如图6所示，图中虚线所示水流路径，箭头所示流向，外圈密封垫一3-1、外圈密封垫二3-2、外圈密封垫三3-3、外圈密封垫四3-4、外圈密封垫五3-5、外圈密封垫六3-6、外圈密封垫七3-7和壳体内腔一1-6的内壁贴合密封，内圈密封垫一3-16、内圈密封垫二3-15与凹槽一4-4左侧的活塞体一4-3外圆面贴合密封，将废液口1-2关闭。内圈密封垫四3-13、内圈密封垫五3-12与凹槽一4-4右侧的活塞体一4-3外圆面贴合密封，将原水和软化水分隔开。盐阀密封垫一3-8、盐阀密封垫二3-9与凹槽二4-7右侧的活塞体二4-6外圆面贴合密封，将再生液入口1-10关闭。
原水从原水入口1-5进入壳体1，经过凹槽一4-4从流道六1-13穿过上部水流分散器6进入罐体5，经过软化介质8将原水软化，软化后的软水穿过下部分散器9，经过中心管7从流道四1-11进入壳体1，绕过活塞体二4-6，从软水出口1-7流出。实现了原水的软化，同时关闭了废液口1-2和再生液入口1-10，不会造成水的损耗。
反冲洗
如图7所示，内圈密封垫三3-14与凹槽一4-4左侧的活塞体一4-3外圆面贴合密封，内圈密封垫七3-10、内圈密封垫六3-11、内圈密封垫五3-12与凹槽一4-4右侧的活塞体一4-3外圆面贴合密封。盐阀密封垫一3-8、盐阀密封垫二3-9与凹槽二4-7左侧的活塞体二4-6外圆面贴合密封，将再生液入口1-10关闭。
原水从原水入口1-5进入壳体1，经过凹槽一4-4、流道五1-12及中心管7，穿过下部水流分散器9进入罐体5，将再生介质8上部的杂质冲出，同时将再生介质冲松散，便于下次软化时水流通过。带有杂质的液体经过上部分散器6、流道六1-13、从壳体废 液口1-2流出。
吸盐位
如图8所示，内圈密封垫三3-14、内圈密封垫二3-15与凹槽一4-4左侧的活塞体一4-3外圆面贴合密封，内圈密封垫六3-11、内圈密封垫五3-12、内圈密封垫四3-13与凹槽一4-4右侧的活塞体一4-3外圆面贴合密封。盐阀密封垫一3-8与凹槽二4-7左侧的活塞体二4-6外圆面贴合密封。
原水从原水入口1-5进入壳体1，经过流道二1-4进入虹吸器2的原液口2-5，喷射腔2-3喷射产生负压，再生介质在大气压力下从壳体1的再生液入口1-10进入，经过活塞体二4-6的凹槽二4-7、流道1-8、再生液口2-4在喷射腔2-3处与原水混合，混合后的液体经过流道一1-3进入壳体1，绕过活塞体一4-3，从流道六1-13穿过上部水流分散器5进入罐体，将软化介质8恢复功能，残留再生液经过下部水流分散器9、中心管7，从流道四1-11进入壳体1，然后穿过活塞体一的通孔4-2，从废液口1-2排出壳体1。
关断位
如图9所示，内圈密封垫二3-15、内圈密封垫一3-16与凹槽一4-4左侧的活塞体一4-3外圆面贴合密封，将壳体1的废液口1-2关闭。内圈密封垫六3-11、内圈密封垫五3-12与凹槽一4-4右侧的活塞体一4-3外圆面贴合密封，将壳体1的软水出口1-7关闭。盐阀密封垫一3-8、盐阀密封垫二3-9与凹槽二4-7右侧的活塞体二4-6外圆面贴合密封，将再生液入口1-10关闭。壳体1的废液口1-2、软水出口1-7、再生液入口1-10都关闭，从壳体1的原水入口1-8不能流出，实现软化阀的全关断功能。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
