下面结合附图 1至图 4以地漏为实施例详细介绍;
图 1是本发明水冲击止逆排水装置的实施例之 1—单阀板水沖击 止逆地漏结构示意图。 该地漏包括固定在地面面层的固定壳 1、 固定 壳上的水箅子 2、在固定壳上方便装卸的长圆管状永磁逆止阀本体 3 , 三个部分。
该地漏基本工作原理是一个铰结单个阀板 8 的直立手势入排水 管道 4的长圆筒状的永磁吸力闭合的逆止阀, 当进水量小, 水位未达 到设定的触开高度时, 阀板 8不开启, 避免小水流造成的泥沙和碎屑 沉积堵塞水平排水管的现象; 当进水超过设定的阀板 8触开水位时, 水压超过阀本体 3内的磁体与阀板 8的永磁吸引力,立即触开阀板 8, 全部开启, 迅速排水, 产生水冲击, 有利于清洗排水管道; 当进水量 大, 则阀板 8不闭合, 通流量达到最大; 当排水管道 4内突然出现负 压时, 则对管道自动补气, 自动维持管内常压; 然后及时恢复止逆封 堵,完全避免了发生扣碗式地漏及返水弯内水封被吸干而造成防臭功 能失效的普通现象。 该装置内既使完全无水, 仍可正常封堵, 不需要 人为补水, 省心。
该地漏其总高度大于其长圆管状的逆止阀本体 3的阀口 5口径的 最大尺寸 1. 5倍以上, 已容纳足够的水压触开阀板,最好使地漏其总 高度大于其长圓管状的逆止阀本体 3的阀口 5口径的最大尺寸 3倍以 上。 固定壳 1有膨大的内腔, 以容纳较多的水量, 以便有更大的水冲 击量。 阀本体 3直立插入排水口管道 4内, 并同轴线, 这种方式占用 地面空间小, 给施工和做防水带来很大方便。 长圆管状的阀本体 3通 过短螺紋或坡形凸台 12与固定壳 1 固定或卸下, 便于整体清理与检 修。 阀本体 3与固定壳 1安装时, 是通过密封圏 13实现压力密封。 为防止阀本体 3插入排水管道 4偏心, 固定壳 1下端插入排水管道 4 的缩径部分的外径与标准规格的排水管道 4内径尺寸为间隙配合;其 长度不小于 2. 5厘米; 以于以外径尺寸做为标称尺寸的排水管道 4 , 固定壳 1的下端应插到排水管外,插入深度部位长度不小于 2. 5厘米, 以适应楼板及垫层的不同厚度,调整其高度的方便。在施工安装时与 排水管道 4之间涂密封膏 18。
大小恰好覆盖阀口 5的阀板 8是以一个边铰结自由悬挂在轴 14上 的, 轴 14是固定在长圆筒状阀本体 3的阀筒 6下端水平中轴线上, 阔 板可自由摆动, 轴 14选择在阀筒 6下端和水平中轴线上, 是为获得大 的水冲击量和阀板 8最大的开度, 减小流阻。
阀板 8的密封口 11中央部位固定一 7j ^兹块 10,其与固定在阀筒 6 内阀口 5支柱体 Ί上的软磁螺栓 9在阀板 8闭合状态时, 两者位置对 应, 并互相吸引, 实现对阀口 5的密封和水位在超过设定触开高度时 阀板 8瞬间全部开启。
永磁块 10选择在密封口 11的中央部位,是为了保证四周压力分 布尽量均匀, 以便更好的密封, 并且成本低。
通过调整螺栓 9的伸出高度,或釆取磁体的其它安置方式, 为调 整阀板 8 对排水口的闭合吸引压力。 吸力可调的目的是为降低对设 计、 材料、 安装方面的技术要求, 仅需要通过产品出厂调试或按安装 需要在现场调整设定触开水位的高度。
阀板 8的闭合复位, 在排水后, 阀板 8悬挂在轴 14上自然下垂 状态, 在永磁块 10与支柱体 7上的软磁螺栓 9的吸力下闭合。
单个阀板 8的一个边以铰结的方式固定在阀筒 6的一侧向内下方 倾斜的坡板 15下端接近阀筒 6水平中轴线的轴 14上, 坡板 15除固 定轴承 14以外, 倾斜是为减小水阻, 导流。 直立长圓筒状的阀筒 6 的下端半球形侧面的阀口 5平面自位于阀筒 6 下端水平中轴线上轴 14的轴线以下部分, 向阀板 8的反方向向下倾斜, 与轴 14轴线的下 垂线夹角小于 40度, 倾斜的目的是为减小水流阻, 导流。
直立阀筒 6内壁下端坡板 15对应的另一侧固定一流线状导流板 16 , 在支柱体 7的正上方, 覆盖着支柱体 7和其软磁螺栓 9 , 并不影 响阀板 8的闭合, 避免了对纤维物的剐带现象; 导流板 16与支柱体 7可以做成一体, 导流板 16与坡板 15之间留有尽可能大的间隙, 以 减少流阻。 又由于阀体 3对排水管道直排, 因而不易堵, 在不装二级 过滤网 17时, 甚至头发、 棉丝、 砂粒等都可顺畅排放。
由于长圓筒形阀筒 6内有较大空间,设有便于卸下的桶状的第二 级过过滤网 17能容纳污水中异物等杂质, 使排水更可靠。
下排水洗衣机管 20, 可以通过卡口 19卡在阀本体 3的口上, 不 漏水, 不跑味。
图 2是本发明实施例之 2—双阀板弹簧复位, 用于在用扣碗式地 漏改造示意图。 去掉实施例 1的固定壳 1, 在阀筒 6上端加锥管形卡 口 21, 上端口大, 外部套有贴紧的锥管形橡胶套管 23, 锥管形卡口 21上部接据力口 22。 改造旧地漏 26时, 将原有扣碗去掉, 再将阀本 体 3和橡胶套管 23插入排水管道 4后, 将扭力口 22拧紧。 阀筒 6外 壁有圓周均布的四根外形尺寸与标准规格的排水管道 4 内径尺寸为 间隙配合的短的阀筒肋 25, 以防止长圓筒状阀筒 6与排水管道 4安 装偏心。
本实施例之 2阀筒 6下端为对称双向开启的双阀板 8A、 8B, 各 阀板的一个边与阀筒 6下端的水平中轴线上的水平中心支撑 24下部 的水平轴 14铰结; 与水平中心支撑 24水平垂直的两支柱体 7A、 7B 中部, 各有一个可调高度的软磁螺栓 9A、 9B, 其位置分别与面对阀 筒阀口 5的阀板 8A、 8B上一面贴有弹性密封材料的密封口 11中部固 定的永磁块 10A、 10B相对应并互相吸引; 在轴 14上, 有辅助闭合的 复位弹簧 27A、 27B, 在与阀板 8A、 8B上的永磁块 10A、 10B与支柱 体 7A、 7B上的螺栓 9A、 9B的吸引力的共同作用下, 使两阀板 8A、 8B复位闭合。
图 3是本发明实施例之 3—双阀板永磁斥力复位地漏方案局部示 意图, 阀筒 6下端的水平中心轴线对称分布的两个阀口 5A、 5B平面, 与水平轴 14向下垂直平面的夹角对称, 且均小于 60度; 两阀板 8A、 8B铰结于水平中心支撑 24的轴承 14上, 两阀板 8A、 8B中央位置的 永磁块 10A、 10B与阀筒 6两侧支柱体 7A、 7B上的软磁性螺栓 9A、 9B分别对应相吸。 支柱体 7A、 7B上方有导流板 16A、 16B, 覆盖支柱 体 7A、 7B和螺栓 9A、 9B; 在水平中心支撑 24的下端, 延伸一个两 阀板的辅助复位支架 28, 下端固定一个永磁块 10C, 其两侧磁极的极 性分别与相对应的两阔板 8A、 8B中心部位永磁块 10A、 10B极性相斥, 并斥力与磁块 10A、 1 OB对应的软磁螺栓 9A、 9B的引力合力足以使阀 板 8A、 8B送达相应的阀口 5A、 5B。
本发明水冲击止逆排水装置阀本体 3 也单独适用于容器底部的 排水口上, 并取消返水弯。
