参阅以上各图及图 122， 把主阀活塞组安装于主阀腔 2中， 副阀活塞组安装于 副阀腔 3中， 使它们中的活塞体底板 25朝下， 使活塞组上的连通的小孔 19朝向阀腔 中阀口 10上的缺口 7的方向； 在主副阀盖 11与主阀活塞体 18、 副阀活塞体 21之间放 置强度适宜的弹簧， 且使副阀活塞组的副阀活塞体 18中的凸部 22的上端正好位于 延伸至副阀腔 3的出水槽 5的下端， 这样当副阀活塞组上移时， 出水槽 5会被副阀活 塞体 18中的凸部 22挡住， 也即关闭了出水槽 59 (参阅图 120、 图 121 ) ； 再把合适 的密封圈放置在主副阀盖密封圈槽 4中， 最后把主副阀盖 11用螺丝固定于主副阀体

参阅图 79、 图 80、 图 81、 图 82至图 107、 图 108、 图 109、 图 110、 图 125、 图 129， 先把二个浮体 55安装到浮筒罐 59的主阀部 A及副阀部 B的外底部上的二个浮体 孔 61中； 把二对浮筒转动座从浮筒罐 59的外底部分别插入二对转动座槽 63中； 把 主阀浮筒 64安装到浮筒罐 59的主阀部 A上， 使主阀浮筒 64下端的一对转动脚 65卡进 已安装牢固的一对浮筒转动座的转动脚孔 53中； 把副阀浮筒 66安装到浮筒罐 59的 副阀部 B上， 使副阀浮筒 66下端的一对转动脚 65卡进已安装牢固的一对浮筒转动座 的转动脚孔 53中。 这样就形成了一个浮筒罐组。
把先前装配好的阀体组中的进水管 56插入刚刚装配好的浮筒罐组中的浮筒罐 主阀部 A外的进水管孔 60中， 对正角度后并一插到底， 再把浮筒罐卡扣 58卡入进水 管 56上的浮筒罐卡扣槽 57中， 再把浮筒罐组中的主阀连接杆 42与副阀连接杆 44的 另一端上的转动轴 43分别安装到对应的主阀浮筒 64与副阀浮筒 66上端的连接杆转 动轴孔 40中， 最后把进水管垫片 48套入进水管 56的下部， 并在出水接头 34的出水 口套上软管使软管的另一头在浮筒罐 59的下面。 这样， 本发明的自闭式节水装置的所有部件都已安装完毕， 参阅图 128、 图 参阅图 130， 在便器 67中有喷射口 72， 在水箱 68内有排水组件 69， 把本发明的 自闭式节水装置 70整体安装在水箱 68内， 只有进水管 56的在进水管垫片 48下面有 螺纹的一端在水箱外， 把此端用软管与外接水源或自来水连接起来， 再把本发明 的自闭式节水装置 70中的喷射助推接头 33与便器 67中的喷射口 72用软管 71连接起 来， 这样本发明的配备有自闭式节水装置的便器也安装完毕。 下面先粗略介绍一下本发明的自闭式节水装置内的主副阀的工作原理： 其实本发明的自闭式节水装置内的主副阀的开闭原理与普通的自闭式进水装 置内部的阀的开闭原理或普通的电磁阀等的开闭原理一样， 都是通过开闭泄压小 孔控制阀内部的压力差来达到开闭阀的。
参阅图 124的左边副阀部， 在副阀腔 3的四周进水部有水流 C及水流 F， 由于活 塞体皮碗 23为大小头的可单向扩大的锥形皮碗且有斜口 24， 所以水流 F只能使活塞 体皮碗 23的斜口 24扩张而不能从斜口 24通过， 这样副阀腔 3就被副阀活塞组分成了 上下二部， 但水流 N仍能从副阀活塞体 21上的小孔 19通过而到达副阀活塞组的上 部；
在泄压小孔 16被阀臂橡胶塞 49压住时也即泄压小孔 16关闭时， 副阀腔 3内的副 阀活塞组上部压强由于小孔 19的连通与下部压强一样大， 副阀活塞组上部的受力 面积为副阀腔 3的横截面积， 副阀活塞组下部的受力面积为副阀腔 3的横截面积减 去阀口 10的横截面积， 所以副阀活塞组受到的向下的水压力大于向上的水压力， 再加上弹簧 30的向下弹力， 副阀活塞组一定是下移的， 即副阀活塞组上的活塞体 密封板 26压在阀口 10上， 也即副阀呈关闭状态；
参阅图 123的左边副阀部， 在泄压小孔 16与阀臂橡胶塞 49离开时也即泄压小孔 16开启时， 副阀活塞组上部的水流 M通过泄压小孔 16流出， 虽然水流 N仍能从副阀 活塞体 21上的小孔 19通过而到达副阀活塞组的上部， 但由于泄压小孔 16比小孔 19 大很多， 从小孔 19通过而到达副阀活塞组的上部水流 N不足以补充通过泄压小孔 16 流出的水流 M， 副阀活塞组上部的压强就会陡然减小， 虽然此时副阀活塞组上部的 受力面积仍大于下部的受力面积并且仍还有弹簧 30的向下弹力作用， 但由于副阀 活塞组上部的压强减小而使副阀活塞组上部受到的向下水压力与向下的弹簧 30的 弹力的合力小于其下部受到的向上水压力， 所以副阀活塞组就上移， 即副阀活塞 组上的活塞体密封板 26与阀口 10分离， 也即副阀打开。 综上所述， 当有水流经过时， 泄压小孔 16关闭副阀就被关闭， 泄压小孔 16开 启副阀就被开启， 只要控制了泄压小孔 16的开闭， 也就控制了副阀的开闭；
对比参阅图 116中主阀部与副阀部及图 117， 主阀与副阀的主要结构一样， 开 闭原理一模一样， 当有水流经过时， 泄压小孔 15关闭主阀就被关闭， 泄压小孔 15 开启主阀就被开启， 只要控制了泄压小孔 15的开闭， 也就控制了主阀的开闭； 下面介绍本发明的自闭式节水装置 70整体安装在便器 67的水箱 68内时阀体外 部阀控制机构各部件在不同时刻的各种状态及工作原理：
参阅图 112、 图 114， 在水箱进满水时也即浮筒罐 59内有水时， 由于受到浮力 的作用， 主阀浮筒 64与副阀浮筒 66都会沿转动脚 65上浮转动到竖立状态， 同时它 们下面的浮体 55也各自上升到上浮状态。 其中， 副阀浮筒 66在上浮至最高端时完 全在浮筒罐 59的副阀部 B内且其顶端离副阀部 B上沿还有一定距离。
参阅图 111、 图 113， 在水箱排完水时， 浮体 55由于失去了浮力的作用而下 移， 浮筒罐 59内的水会从其底部的浮体孔 61流出， 浮筒罐 59内无水后， 主阀浮筒 64与副阀浮筒 66也就失去了浮力的作用， 它们就都沿转动脚 65转动到斜立状态。
对比参阅图 111中的浮体 55的脚 14与图 113中的浮体 55的脚 14， 副阀部 B的外底 部的浮体 55的脚 14相对于主阀部 A的外底部的浮体 55的脚 14较短， 即在副阀部 B的 外底部的浮体 55下移距离较小， 也即在水箱排水时使副阀部 B底部的浮体孔 61开启 较小。
参阅图 125， 在水箱进满水主阀浮筒 64与副阀浮筒 66都转动到竖立状态时， 主 阀连接杆 42与副阀连接杆 44也都呈竖立状态， 与它们相活动连接的主阀臂 37与副 阀臂 41的一端也都呈上转状态。
参阅图 127， 在水箱排完水主阀浮筒 64与副阀浮筒 66都转动到斜立状态时， 主 阀连接杆 42与副阀连接杆 44也都呈斜立状态， 与它们相活动连接的主阀臂 37与副 阀臂 41的一端也都呈下转状态。
参阅图 131、 图 132， 主阀臂 37上有连接杆转动轴孔 40的一端上转， 主阀臂 37 的有阀臂橡胶塞 49的另一端就会下转， 通过杠杆作用， 从而使主阀臂 37上的阀臂 橡胶塞 49压住主副阀盖 11上的主阀泄压小孔 15， 主阀泄压小孔 15就会被关闭； 反 之， 主阀臂 37上有连接杆转动轴孔 40的一端下转就会使主阀泄压小孔 15被开启。
参阅图 133、 图 134， 副阀臂 41上有连接杆转动轴孔 40的一端上转， 副阀臂 41 上的阀臂橡胶塞 49会跟着上转， 此阀臂橡胶塞 49会与主副阀盖 11上的副阀泄压小 孔 16离开一小段距离， 也即副阀泄压小孔 16被开启， 反之， 副阀臂 41上有连接杆 转动轴孔 40的一端下转就会使副阀泄压小孔 16被关闭。
综上所述， 当主阀浮筒 64上浮转动到竖立状态时， 主阀泄压小孔 15就会被关 闭， 当主阀浮筒 64下转到斜立状态时， 主阀泄压小孔 15就会被开启； 当副阀浮筒 66上浮转动到竖立状态时， 副阀泄压小孔 16就会被开启， 当副阀浮筒 66下转到斜 立状态时， 副阀泄压小孔 16就会被关闭。
综合前述的主副阀的工作原理， 可以得到以下结论： 当主阀浮筒 64上浮转动 到竖立状态时， 主阀被关闭， 当主阀浮筒 64下转到斜立状态时， 主阀被开启； 当 副阀浮筒 66上浮转动到竖立状态时， 副阀被开启或处于可开启状态， 当副阀浮筒 66下转到斜立状态时， 副阀被关闭。 下面介绍本发明的自闭式节水装置 70整体安装在便器 67的水箱 68内时的工作 过程：
参阅图 111、 图 113、 图 127、 图 130， 在便器 67的水箱 68内本来无水， 当时本 发明的自闭式节水装置 70外部各部件状态如图 127所示， 当时主阀浮筒 64与副阀浮 筒 66都呈斜立状态； 参阅图 124、 图 132、 图 133， 当时主阀泄压小孔 15开启， 副阀 泄压小孔 16关闭， 当有外接水源或自来水通过水箱外的进水管 56有螺纹的一端向 水箱进水时， 水流 A使主阀活塞组上移， 即主阀活塞组上的活塞体密封板 26与主阀 腔 2内的阀口 10分离， 阀口 10内就有水流 B流入， 这样副阀腔 3的四周进水部就有水 流 C流入， 这样在副阀活塞体 21的下端凸部 22上面就有水流 F流入， 参阅图 120， 水 流 F会沿着凸部 22上面到达出水槽 5， 出水槽 5中就会有水流 G流出， 水流 G会经过出 水接头 34及软管最终流入水箱， 水箱开始进入进水状态。 （当时由于副阀泄压小 孔 16关闭而副阀不能打开） 当时本发明的自闭式节水装置 70内部各部件状态如图 124、 图 120所示。
参阅图 128， 随着水流 G经过出水接头 34及软管不断流入水箱内， 水箱内水位 渐渐升高， 由于在浮筒罐 59的主阀部 A与副阀部 B的外底部分别有起单向阀作用的 浮体 55， 所以在水箱内水位从浮筒罐 59的底部上升到上沿部的过程中， 主阀部 A与 副阀部 B都不会进水， 只有少量的渗水， 不足以产生浮力使主阀浮筒 64与副阀浮筒
66上浮转动， 只有当水位到了主阀部 A的上沿时， 水流才会从主阀部 A的上沿进入 主阀部 A内， 当有水进入后， 其内的主阀浮筒 64才会由于受到浮力的作用而上浮转 动， 从而使主阀泄压小孔 15关闭并最终关闭主阀， 主阀关闭后， 水流 G的源头没有 了， 出水接头 34及软管也就无水可出， 水箱的进水就停止了， 当时本发明的自闭 式节水装置 70外部各部件状态如图 128所示。
参阅图 125、 图 122， 因为浮筒罐 59的主阀部 A的上沿低于副阀部 B的上沿， 所 以当主阀部 A内有水进入时副阀部 B内还不会有水进入， 只有当主阀部 A内的水进满 后， 也即主阀浮筒 64上浮转动关闭主阀后， 才会有水从主阀部 A与副阀部 B互通的 小缺口 62流向副阀部 B内， 等到副阀部 B内的水差不多流满后， 副阀部 B内的副阀浮 筒 66也会由于受到浮力的作用而上浮转动， 从而使副阀泄压小孔 16开启， 而此时 主阀已被关闭， 副阀没有了进水， 虽然泄压小孔 16开启也不会被打开， 副阀只是 处于一种待开启状态， 只要一有水流从主阀的出水口流入就可以立刻被打开。 当 时本发明的自闭式节水装置 70外部各部件状态如图 125所示， 内部各部件状态如图 122所示。
参阅图 126、 图 123， 当打开水箱 68内的排水组件 69使水箱排水时， 随着水箱 内水位的快速下降， 浮筒罐 59的主阀部 A的外底部的浮体 55由于没有了浮力的作用 就会下移， 主阀部 A内的水就会马上排空， 随之主阀浮筒 64也就立刻下转， 从而使 主阀泄压小孔 15被开启， 水流 A使主阀活塞组上移， 即主阀活塞组上的活塞体密封 板 26与主阀腔 2内的阀口 10分离， 主阀腔 2的阀口 10内就有水流 B流入， 这样副阀腔 3的四周进水部就有水流 C流入； 同时也有微小水流 L从主阀泄压小孔 15流出， 流出 的水被流入水箱内。
虽然随着水箱排水时内部水位的快速下降， 浮筒罐 59的副阀部 B的外底部的浮 体 55也同时会由于没有了浮力的作用而下移， 但由于副阀部 B的外底部的浮体 55的 脚 14相对于主阀部 A的外底部的浮体 55的脚 14较短， 所以在副阀部 B的外底部的浮 体 55下移距离较小， 也即使副阀部 B底部的浮体孔 61开启较小， 又副阀浮筒 66顶端 离副阀部 B上沿又有一定的水量， 所以在副阀部 B内的水不会立刻流尽， 副阀浮筒 66在一定时间内还会呈上浮状态， 也就是还能使副阀泄压小孔 16保持开启状态， 当有水流 C流入副阀腔 3的四周进水部时， 水流 C使副阀活塞组上移， 即副阀活塞组 上的活塞体密封板 26与副阀腔 3内的阀口 10分离， 也即使得副阀被开启， 副阀腔 3 内的阀口 10内就有水流 D流入， 并使喷射助推接头 33上有水流 E流出； 同时也有微 小水流 M从副阀泄压小孔 16流出， 流出的水被流入水箱内； 当时本发明的自闭式节 水装置 70外部各部件状态如图 126所示， 内部各部件状态如图 123所示。
参阅图 130， 从喷射助推接头 33上流出的水流 E通过软管 71使便器 67中的喷射 口 72中有水流 H喷出， 从而推动水箱排放出的流入便盆或便盆底部或排污管道底部 的水。 参阅图 121， 在副阀活塞组上移即副阀打开时， 在副阀活塞体 21下端的一圈凸 部 22也上移， 这样就堵住了出水槽 5， 使水流不能通过出水槽 5向水箱内流水， 这 样能使从喷射助推接头 33上流出的水流 E的压力最大化。
再次参阅图 124、 图 127、 图 120，等到过了一段时间后， 浮筒罐 59的副阀部 B内 的水量渐渐流尽， 在其内部的副阀浮筒 66由于失去了浮力的作用而下转， 这样就 会使副阀泄压小孔 16被关闭， 也即副阀被关闭， 即副阀活塞组下移， 也即副阀活 塞体 21下端的一圈凸部 22下移， 从而开启了刚才堵住的出水槽 5， 水流 F会沿着凸 部 22上面到达出水槽 5， 出水槽 5中就会有水流 G流出， 水流 G会经过出水接头 34及 软管最终流入水箱， 水箱又开始进入进水状态。 当时本发明的自闭式节水装置 70 外部各部件状态如图 127所示， 内部各部件状态如图 124、 图 120所示。
至此， 本发明的自闭式节水装置 70的所有部件都已开始进入了下一轮的循 环。 需要补充说明一下的是：
把浮筒罐 59的主阀部 A的上沿设计成低于副阀部 B的上沿， 而不是让它们相 平， 是为了当水箱内水位上升时它们不会同时进水， 若同时进水的话， 副阀浮筒 66会马上上转， 即打开了副阀， 而此时主阀浮筒 64虽然也同步马上上转， 但不会 即刻关闭主阀， 这样副阀就会短暂的开启从而导致喷射助推接头 33上有短暂的出 水。
本行业的阀类专业人员可以通过改变阀的内部部件来改变本发明的具体内部 结构， 如调换主副阀活塞组的位置， 或都用主阀活塞组， 或都用副阀活塞组； 或 把主副阀活塞组的活塞移动式结构整体改变为与普通的自闭式进水装置或普通的 电磁阀等内部结构一样的皮碗移动式结构； 上述所有改变都属于本发明的保护范 围。
