Description
技术领域
本公开内容涉及一种端部密封倾斜阀。更具体地,本公开内容涉及一种用于加压分配容器的端部密封倾斜阀。
背景技术
多种不同类型的产品在容器中出售,所述容器包括端部阀以使消费者能够获取容器中的物品。例如,产品(诸如发泡剃须凝胶、发泡牙膏、各种食品以及发泡发用产品)在具有端部阀的容器中出售。消费者偏转设置在包含产品的容器上的倾斜阀来从容器中释放产品。
这种发泡产品可能会导致“后流淌”(“afterdrool”),即保留在阀密封下游的任意产品通道中的产品量膨胀并从容器的产品输送孔中挤出。
下面描述的方法和***减少或避免这种“后流淌”或不需要的产品分配,例如,以使得在阀关闭后,使暴露于大气的食品量减少到接近于零,并且由此将潜在的损失最小化。
本公开内容还提供了许多额外的优点,这些优点将在下文中描述。
发明内容
本公开内容了提供一种阀,所述阀包括端部密封组件、外壳和安装座。所述安装座具有孔。所述部密封组件具有通过所述孔的第一部分,从而在所述安装座和所述端部密封组件的所述第一部分之间形成间隙。所述外壳连接至所述安装座。所述端部密封组件具有在所述外壳中的第二部分。壳密封件在所述外壳和所述端部密封组件之间,从而覆盖所述间隙。所述壳密封件能够在通过所述间隙施加预定压力时变形,以在所述外壳和所述端部密封组件之间形成开口。

具体实施方式
参考附图,特别是图1,示出了根据本公开内容的端部密封倾斜阀的示例性实施方式在关闭填充位置,并且端部密封倾斜阀总体上以参考标记100(“阀100”)表示。阀100具有由壳体105和阀杆110形成的端部密封组件102。阀100具有安装座115、壳密封件120、弹簧125和外壳130。壳体105具有凸缘131、开孔133、密封环135、阀杆环140和肩部145。阀杆110具有端部密封件150、阀杆基部152和枢转点155。弹簧125在阀杆基部152和外壳130之间。安装座115具有卷曲部160和孔165。外壳130具有楔形的形状。间隙170形成在安装座115和壳体105之间。壳密封件120位于安装座115、外壳130和壳体105的凸缘131之间,以在关闭填充位置密封间隙170。向端部密封组件102提供力F,使得端部密封组件102从关闭填充位置沿着力F的方向移动至打开填充位置。
参考图2,阀100在打开填充位置。壳体105的凸缘131远离安装座115移动,从而在打开填充位置在壳密封件120和凸缘131之间形成空间117。壳密封件120能够在通过间隙170施加预定压力时在空间117内变形,以在外壳130和壳体105之间形成开口175。
参考图3,箭头J示出了具有预定压力的流体(例如产品)流过间隙170和开口175。在分配之前,在为了储存产品而进行的产品压力填充过程中,由箭头J示出的产品流可流入具有喷雾分配器(如图中示出的阀口袋喷雾分配器)的袋。当不再向端部密封组件102提供力F时,端部密封组件102从打开填充位置沿着相反于力F的方向移动至关闭填充位置(图1中示出),使得流体不再流过间隙170和开口175。通过由弹簧125提供的力和/或由产品提供的力(由产品提供的力产生于推进剂向储存产品的袋提供的压力),端部密封组件102从打开填充位置沿着相反于力F的方向移动至关闭填充位置,该力推压阀杆110回到关闭分配位置以避免产品分配到阀100外。
参考图4,示出了阀杆110。阀杆110具有柔性部157。枢转点155是柔性的。
参考图5,阀100在关闭分配位置和关闭填充位置。阀100连接至阀口袋喷雾组件300,阀口袋喷雾组件300具有填充有产品310的袋305和填充有推进剂320的容器315。推进剂320向袋305提供压力,以推压产品310沿着箭头K流动。沿着箭头K的流动使端部密封件150压靠壳体105,从而使产品310不会流过壳体105的开孔133。
参考图6,沿着箭头K的产品310的流动向壳体105的支撑端部密封件150的下表面108提供压力。
参考图7,沿着箭头K的产品310的流动向端部密封件150提供压力。
参考图8至图10,向阀100提供力M,以使阀100从关闭分配位置移动至打开分配位置。当阀100保持在关闭填充位置时,向壳体105提供的力M使柔性部157绕枢转点155移动,这样枢纽点155沿着力M的方向弯曲,并且端部密封件150远离开孔133和围绕开孔133的壳体105移动,从而在端部密封件150和壳体105之间形成间隔180。壳密封件120在打开分配位置覆盖间隙170。壳密封件120在打开分配位置接触壳体105、座115和外壳130。阀100连接至阀口袋喷雾组件300。推进剂320向袋305提供压力,产品310被该压力朝向端部密封件150推压,经过外壳130和阀杆110之间,经过壳体105和阀杆110之间,并且流过间隔180,并且流出开孔133,从而从阀100向外分配产品。当不再向壳体105、弹簧125和/或枢转点155提供力M时和/或由产品提供的力(由产品提供的力产生于推进剂320向袋305提供的压力)推压阀杆110回到关闭分配位置以避免产品分配至阀100外。
参考图11,示出了根据本公开内容的端部密封倾斜阀的示例性实施方式在关闭填充位置,该端部密封阀总体上以参考标记500(“阀500”)表示。阀500类似于阀100,但是,具有替代的安装座515。座515具有围绕外壳130的边缘132延伸的卷曲部560。
边缘132和卷曲部160和560避免或消除产品在产品压力填充过程中被迫进入容器315的可能性。
壳体105的轮廓是波形的。如图3所示,在填充操作期间,当阀100沿力F的方向轴向被完全地压下时,肩部145与孔165重合或邻近;座115和壳体105之间的间隙170的宽度因壳体105的外径在肩部145处的减小而增加。在产品分配期间,在阀杆110被完全地轴向压下时将产品的填充速度最大化,同时保持壳密封件120的完整性。
阀杆110被“缩颈”或具有枢转点155,以减小阀100、500从关闭分配位置移动至打开分配位置的力,并为在阀杆110和壳体105部件之间的差异移动建立特定的枢转点,由此提供一致的打开产品流动轮廓。
端部密封件150的下游端成形为利用容器300的内部压力来补充弹簧125的机械弹簧压力,以确保在试验(rest-test)时有效的密封件可以证明在满足阀100、500功能的条件下不一定必须需要弹簧-这对于接触金属部件可能导致降解的产品是有利的。
通过提供一致的壳体105的顶部表面轮廓和孔的几何形状,改善了阀100、500的密封功能。通过使阀弹簧的关闭力和筒体压力集中在较小的表面区域上,可以强化密封环135和/或阀杆环140的密封性能。
通过将端部密封件150下游的产品通道最小化,从端部密封件150至开孔133的距离减少或消除“后流淌”或不需要的产品分配。
还应注意的是,本文中使用的“第一”、“第二”、“第三”、“上”、“下”之类的术语可能用来修饰不同元件。除非特别说明,这些修饰词并不意味着所修饰的元件有空间次序、顺序、或等级次序。
虽然已经参考一个或多个示例性实施方式描述了本公开内容,但本领域技术人员可以理解,在不背离本公开内容的范围的情况下,可以进行各种改变或元件的等同替换。此外,在不背离本公开内容的范围的情况下,可以作出许多修改以使特定的情况或材料适应本公开内容的教导。因此,意图是,本公开内容不限于作为设想的最佳方式所公开的特定实施例,并且本公开内容将包括所有落在所附权利要求的范围内的所有实施方式。
