Description

增强虹吸法兰 本申请要求于 2009 年 3 月 3 日提交中国专利局、 申请号为 200910078730.2、 发明名称为 "增强虹吸法兰"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明属于日用卫生设备领域， 涉及一种适用于下排水坐便器用的安 装法兰。 背景技术
在设计节水便器时， 目标是一次冲洗使用尽可能少的水完成坐便器的 各项基本功能（GB6952-2005 ) ： 1、 冲净功能； 2、 固体物排放功能； 3、 污水置换功能； 4、 水封回复功能； 5、 排水管道输送功能； 6、 防浅功能。
目前， 现有下排水便器实际安装时， 其排污口与竖直设置的地排污管 连通； 同时， 在便器排污口与地排污管之间一般安装密封法兰， 以防止污 水泄漏。
有鉴于此， 为进一步提高便器使用时的虹吸能力， 除了改进冲洗配件
(冲洗阀） 、 便器的内功能外， 亟待另辟蹊径提出一种新的设计方案。 发明内容
本发明解决的技术问题在于， 提供一种增强虹吸法兰， 以有效利用排 污管的内部空间实现增强虹吸的性能， 从而提高污水排出的流速。
本发明提供的增强虹吸法兰， 用于下排水坐便器的安装； 包括法兰盘 和增强虹吸管， 其中， 所述法兰盘设置于下排水坐便器的排污口下方， 且 两者之间设置有密封胶； 所述增强虹吸管置于地排污管内，其上端部与所 述法兰盘的下端部封固连接。
优选地， 所述增强虹吸管具体为竖直管， 在所述竖直管的下端部封固 连接有薄膜管。
优选地， 还包括保护外管， 套装于所述薄膜管的外侧， 且其与所述竖 直管固定连接。 30mm ~ 70mm。
优选地， 所述薄膜管的两侧分别沿轴向压粘， 以在静止状态下， 薄膜 管出口成扁嘴形。
优选地， 与弯头状地排污管相适配的， 所述增强虹吸管具体为弯管； 在所述弯管的出口端部设置有薄膜片， 且该薄膜片的上沿与所述弯管的出 口的上沿固定连接、 其下沿与所述弯管的出口的下沿之间具有间隙。
优选地， 所述弯管下方的折弯段和水平段与弯头状地排污管相抵接。 优选地， 所述增强虹吸管的内径为 41 mm ~ 55mm。
优选地， 所述法兰盘整体呈上大下小的锥台状， 且该法兰盘的上缘设 置有径向伸出的第一凸沿、 其下缘设置有轴向伸出的第二凸沿。
优选地， 所述第一凸沿与安装地基之间设置有密封胶。
施工安装完成后， 通过密封胶可以使得便器的排污管道、 法兰盘与增 强虹吸管之间形成一个封闭的刚性连通管道组合。 冲洗时， 增强虹吸管内 充满水， 并在这一段形成虹吸； 对于自身具有虹吸功能的便器而言， 这相 当于增加了虹吸落差； 对于冲落式的便器而言， 相当于在其后端增加了一 段虹吸管， 从而加大了排水的流速与冲净能力。 与现有技术相比， 本发明 具有下述有益的技术效果：
首先， 本发明提供的增强虹吸管置于地排污管内， 利用了地排污管所 提供的空间， 可有效地增强下排水坐便器的虹吸性能， 从而提高了污水排 出的流速； 同时， 更有利于固体物排放功能、 污水置换功能以及排水管道 输送功能等三项功能的实现。
其次， 在本发明的优选方案中， 增强虹吸管的下端安装了延长虹吸的 薄膜管， 由于薄膜周围的空气压力与薄膜表面对水的吸附， 可以在一定范 围内使薄膜管随水流的大小进行扩胀或者缩回， 从而可以延长与调控空气 从增强虹吸管下端进入管内的时间，使得更容易形成虹吸并提高洗净程度。
再次， 本发明另一优选方案中， 增强虹吸管具体为与弯头状地排污管 相适配的弯管， 如此设计， 既可最大限度地加长增强虹吸管的长度， 也可 进一步提高管道输送能力。 附图说明 图 1为具体实施方式一所述增强虹吸法兰的安装示意图； 图 2为具体实施方式二所述增强虹吸法兰的安装示意图；
图 3是图 2中 A向所示的薄膜片与增强虹吸管之间配合关系示意图。 图中：
便器排污口 1、 1 '、 地排污管 2、 2'、 法兰盘 3、 y、 密封胶 41、 41 '、 密封胶 42、 42'、 增强虹吸管 5、 薄膜管 6、 保护外管 7、 增强虹吸管 8、 薄膜片 9。 具体实施方式
下面将结合说明书附图具体说明本实施方式。
请参见图 1 , 该图示出了一种增强虹吸法兰的安装示意图。
如图 1所示， 该增强虹吸法兰包括法兰盘 3和增强虹吸管 5 , 其中， 法兰盘 3设置于下排水坐便器的排污口 1的下方， 且两者之间设置有密封 胶 41 ; 具体地， 法兰盘 3整体呈上大下小的锥台状， 且该法兰盘 3的上缘 设置有径向伸出的第一凸沿、 其下缘设置有轴向伸出的第二凸沿。 为稳定 法兰盘 3与便器之间的相对位置的可靠性， 在第一凸沿与地基（图中未示 出）之间设置有密封胶 42。
增强虹吸管 5置于地排污管 2内， 其具体为竖直管且其上端部与法兰 盘 3的下端部封固连接。 增强虹吸管的内径为 41mm ~ 55mm。 冲洗时就可 使增强虹吸管内充满水， 从而在这一段形成虹吸。 实际上， 在地排污管 2 许可的范围内， 可以尽可能的增加增强虹吸管 5的长度， 以有效提高虹吸 效果。
此外， 在竖直管 （即图 1 中所示的增强虹吸管 5 ) 的下端部封固连接 有薄膜管 6。 由于薄膜周围的空气压力与薄膜表面对水的吸附， 可以在一 定范围内使薄膜管随水流的大小扩胀或者回缩， 从而可以延长与调控空气 从增强虹吸管下端进入地排污管 2内的时间， 使得更容易形成虹吸并提高 洗净程度。 优选地， 薄膜管 6的两侧分别沿轴向压粘， 以在静止状态下， 薄膜管 6出口成扁嘴形。
应当理解， 只要增设有薄膜管 6就能够有效提高虹吸效果。 当然， 薄 膜管 6的下沿与竖直段的地排污管 2的下沿之间的距离为 30mm ~ 70mm, 以避免经薄膜管 6流出的液流冲击地排污管 2的水平段后反弹， 可最大限 度的提高虹吸效果。
进一步地， 还包括套装于薄膜管 6外侧的保护外管 7, 且其与竖直管 固定连接， 以避免薄膜管 6受损； 同时， 可改善整体外观效果。
以便器排污口 1的内径为 Φ 46-50mm为例。 增强虹吸法兰可设计为： 法兰 3的出口长 10mm内径为 50mm, 增强虹吸管 5外径的为 50mm, 内 径为 46mm, 薄膜管 6长 150mm, 保护管 7的内径 70mm, 增强虹吸管 5 的长度依照地排污管 2的高度截取， 使得保护管 7的下端到地排污管 2有 30-50mm的 巨离。
请参见图 2, 该图示出了具体实施方式二所述增强虹吸法兰的安装示 意图。
需要说明的是， 本实施方式与具体实施方式一所述增强虹吸法兰的区 别在于， 增强虹吸管与薄膜部件的形状设计不同。 其他组成和连接关系与 具体实施方式一相同。 请一并参见图 3 , 该图示出了图 2中 A向所示的薄 膜片与增强虹吸管之间配合关系。
具体来说， 与弯头状地排污管 2' 相适配的， 增强虹吸管 8具体为弯 管； 在弯管 （即图 2中所示的增强虹吸管 8 ) 的出口端部设置有薄膜片 9, 且该薄膜片 9的上沿与弯管的出口的上沿固定连接（图 3中阴影区域所示；)， 薄膜片 9的下沿与弯管的出口的下沿之间具有间隙， 即虹吸帘式薄膜。 如 此设计，既可最大限度地加长增强虹吸管的长度，也可提高管道输送能力。
由于弯管 (增强虹吸管 8 )内液流冲击较大， 进一步地， 弯管 (增强虹吸 管 8 )下方的折弯段和水平段与弯头状地排污管 1'相抵接，以提高弯管 (增 强虹吸管 8 ) 的工作稳定性。
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。
