Description

双喷射器/四路选择器阀门组件
技术领域
这项发明涉及选择器阀门组件。更具体地说，涉及能连同分发喷射器调节至少四种不同液体材料的流量的选择器阀门组件。
背景技术
选择器阀门连同用来把化学浓缩物混合成液流的喷射器一起使用提供稀释溶液是众所周知的。举例来说，见美国专利第5,377,718、5,653,261和2,881,802号以及美国专利公开第2005/150572 A1、2003/056841 A1和2004/163720 A1号。
虽然这些选择器阀门能控制和选择将被引进喷射器的四种不同的化学浓缩物，但是当从一种化学浓缩物改为选择另一种化学浓缩物的时候存在残存遗留物的问题。这在718号和261号专利中是由使用导槽盘11引起的。
目前所有利用两个分开的喷射器提供高、低流速的选择器阀门系统都为每个喷射器使用两个分开的选择器阀门。这不仅增加该系统的成本和复杂性，而且使该系统变成终端用户更容易误操作的。它们可能有指向一个喷射器的一种产品的选择器阀门而且偶而填充来自第二喷射器的不同的产品。这些类型的系统还需要给分发器贴用于产品确认的标签，这也可能引起误用。
需要一种能连同喷射器混合系统一起使用的选择器阀门，当选择器阀门从一个位置移到另一个位置的时候被用能减少产品遗留物的影响。也需要一种能降低成本和减少误操作的选择器阀门。
所以，本发明的目的是：
a.)提供一种改良的选择器阀门。
b.)提供一种供液体混合和分发装置使用的改良的选择器阀门。
c.)提供一种供喷射器使用的上述类型的选择器阀门。
d.)提供一种能适应两个不同的喷射器的上述类型的单一选择器阀门。
e.)提供一种减少产品遗留物影响的上述类型的选择器阀门。
f.)提供一种使用的零部件数目最少而且减少不适当分发的影响的上述类型的选择器阀门。
g.)提供一种组合的选择器阀门和喷射器组件。
本发明的这些和另一些目的和利益从下面的描述将变得明显。在下面的详细描述中，本发明的优选实施方案将参照本发明的完整范围进行描述。然而，本发明可能用在其它的实施方案中。
发明内容
借助这项发明的能控制至少两条液体流动路径的流量的选择器阀门组件实现了上述的目的并且克服了现有技术的缺点。该选择器阀门组件有一有端壁的隔间的主体构件。在该隔间的端壁中有出口通道，而且至少两条通道与该隔间连通。旋转构件被密封地放置在该隔间中，该旋转构件有侧壁和端壁。第一通道从其端壁伸进该旋转构件一段距离。第二通道穿过其侧壁并且与第一通道连通。旋转构件的旋转将有选择地使第二通道定向于那至少两条通道中的每条通道，以使那至少两条通道中的液体先传送到第一和第二通道传，然后传送到出口通道。
在优选的实施方案中，该选择器阀门组件包括与主体构件连接并且与旋转构件中的第二通道连通的四个通道口。
在一个方面，该选择器阀门组件包括与主体构件连接并且与主体构件的四条通道连通的旋转口。
在另一个优选实施方案中，分度构件与该旋转构件连接。
在另一方面，该选择器阀门组件包括与该分度构件偏置接触的弹簧构件和与主体构件和弹簧构件连接的弹簧保持构件。
在又一个方面，该选择器阀门组件包括操作上与每个旋转口构件相关联的颜色指示器装置。
在又一个优选实施方案中，有与主体构件的出口通道连接的两个喷射器。
在另外一个优选实施方案中，两个喷射器借助止回阀与主体构件的出口通道连接。

具体实施方法
参照图1，选择器阀门组件10是连同两个喷射器12和13一起展示的。优选的喷射器是在通过引证将其教导在此并入的共同拥有的于2005年8月2日申请的美国专利申请第11/195,052号中描述的。该选择器阀门组件10包括阀门构件11，阀杆14藏在管状主体构件15中，该主体构件以流体密封的方式于四个流体摄取口17连接，每个摄取口有一接头19。
如图2所示，该选择器阀门组件10包括安排在阀门构件11和喷射器12、13之间两个止回阀机制20。止回阀20包括止回球22和23。另外，提供球座垫圈26和止回球导向器24以及弹簧28。密封环也以30和32展示出来。
参照图3和5，阀门构件11由穿过主体构件15的狭长孔37、38装配在阀杆14的凹槽40上将阀杆14可拆除地保持主体构件15中的阀杆固定器35组成。分度功能是借助分度盘42和分度受器44提供给为阀杆14的。弹簧46使板42偏置抵住受器44。分度受器44通过主体构件15上的突起45与分度受器44上的缺口 47接合以不可旋转方式保持在阀杆14上。这在图4中看得最清楚，在那张图中还展示用来骑在分度受器44上并且与凹痕41接合的分度盘42上的突起43。分度盘42借助平坦的壁面(其中之一以49表示)和阀杆14的平坦侧面51与阀杆14一起旋转。
如同在图5中最清楚地看到的那样，阀门主体构件15有容纳阀杆14的隔间58。密封环是以52提供的。阀门主体也有端壁60。侧壁62和端壁64是在阀杆14上提供的。通道66从阀杆14的端壁向内延伸到阀杆14中并且与从侧壁62向内延伸到阀杆14中的通道68连接。
也如同在图5中见到的那样，为了与隔间58和阀杆14中的通道68实现流体连通，在摄取口17中提供通道18并且在口外壳56上提供通道57。密封环是以54表示的。人们还将在图5中看到主体构件15有与喷射器12和13的喷射器口70连接的喷射器口71。喷射器口70适应隔间79中的弹簧28以及止回球导向器24。通道77被安排在喷射器口70中并且与隔间79连通。当止回球22和23在主体构件15中抵住阀座75和76的时候，隔间79也适应止回球22和23。通道78位于主体构件中而且与阀杆14和阀座75、76中的通道66连通。
操作
借助关于其操作的描述将较好地理解该选择器阀门组件10。参照图1和5，适当的化学浓缩物来源被接到摄取口17和接头19上，例如用有柔性的管道(未展示)。人们应该理解喷射器12有比喷射器13快的流速。喷射器12和软管72被用于填充桶，而喷射器13和软管74被用于填充瓶子。当需要填充瓶子的时候，增压水被引进喷射器13的入口80。这借助通道77引起对止回球22的虹吸作用，从而使它离开阀座76实现与通道78并依次与通 道66、68流体连通。这在摄取口17提供虹吸作用，把化学浓缩物依吸进通道18、通道68和66、通道78、隔间79并且越过摄取口82进入通道77。最后以众所周知的方式被引进喷射器13中的水流。
当需要填充桶的时候，增压水被引进喷射器12的入口81。这借助通道77引起止回球23上的压力下降，从而使它离开阀座75，如同先前结合喷射器13解释的那样在通道78和通道66和68中产生虹吸作用。这也如同先前解释的那样把化学浓缩物吸进喷射器12和软管72。人们应该注意到，当虹吸作用在止回球22、23之一上产生的时候，另一个止回球借助弹簧28和移开另一个止回球的减少的压力抵住其相应的阀门密封件。
当需要把不同的化学浓缩物引进喷射器12和13的时候，旋转阀杆14，使通道68对准不同的摄取口17。旋转由于分度盘42借助留在用卡簧50固定到阀杆14上的弹簧固定器48中的弹簧46被弹簧加载抵住分度受器44而变得容易。分度盘42和分度受器44之间的分度是以众所周知的方式实现的。这个特征提供阀杆14的主动定位和音响指示器。
为了保证适当的化学浓缩物与适当的摄取口17连接，不同颜色的彩条可以与不同的摄取口联系起来，例如，在图1中以84展示的那样。
该选择器阀门组件10的重要特征是阀杆14中的通道66和68。当通道68从一个摄取口17移到另一个摄取口的时候，这个特征使从一种化学浓缩物到另一种化学浓缩物的遗留比较少。其原因是阀杆14的圆筒形结构对于喷射器12和13充当无缝的、连续的化学路径。通道66和68优选有0.104英寸的直径，这将以最小量的产品遗留物提供最大的浓缩物流量。通道66、68和 隔间79和喷射器通道77的组合体积是0.635毫升。另外，止回球22，23分别与阀座76、75之间的公用通道78被分开不足0.100″。这与用于止回阀20的隔间79的尺寸和喷射器通道77的尺寸结合将化学浓缩物的滞留减到最少。
另一个重要特征是操作可靠性。为了维修回转的阀杆14或阀门圆筒，所需要的只是拆除卡簧50和35。阀杆14能被笔直拉出来，不需要把选择器阀门组件10从喷射器12和13上移开或把喷射器80和81和阀门组件10从歧管的水阀上移开。弹簧固定套48与阀杆14或手柄连接防止卡簧35退出使用期间的位置。
阀门组件10考虑到单一阀门构件与两个喷射器一起使用。这将约成本。它也准备了非设备标签，在这种情况下产品是自己的标签而该选择器阀门将指向意向中的产品。这也考虑到单一电路是否增添用来远程监控化学用法的电子线路或电子指示器(闪光、LED，等等)以便进一步加强适当的产品选择。
用来制造选择器阀杆14的优选材料是Teflon
Figure 2006800328096_0
。主体构件15优选用聚丙烯制造。然而，其它可模塑成形的塑料材料(例如，聚丙烯共聚物)可能被采用。
分度盘42上的爪提供制动和选择器阀门组件10的位置的声音指示。如果需要，它可能被除去，因为它可能是颜色条84。虽然选择器阀门组件10是用四个化学浓缩物摄取口17举例说明的，但是该选择器阀门能用较少(例如，两个)或较多的(例如，八个)的摄取口操作。在本发明的精神范围内这样的修正将全部落在权利要求书限定的范围之内。
