Description

瓶装液体分配器及其阀总成 技术领域
本发明涉及一种用于将瓶装液体(尤其是饮料,例如碳酸饮料)进行分配的分配器,尤其涉及用于该类分配器上的阀总成。
背景技术
现有的饮料供应通常借助复杂的机电化饮料分配机实现。这种设备常见于餐馆,供用户使用。然而,由于体积大、成本高、或在部分地区缺乏电力供应,这种设备通常不实用。此外,这种设备通常与非市售的大体积的筒一起使用,因此成本相对较高。
一些饮料分配器借助于一个管连接至一个大尺寸瓶子( 例如,2 升的瓶子),将饮料( 例如碳酸饮料) 从这个大尺寸瓶子分配至小尺寸的容器( 诸如杯子、袋子或碗)。然而,在该分配器工作时,由于在大尺寸瓶子内产生的真空效应,若不挤压瓶子使其变形,则几乎不可能将所有饮料从瓶子中倒出。即使在装有碳酸饮料的情况下( 碳酸饮料可在瓶子内产生较高的压力),在低温时( 例如4℃ ) 也仅能以低且不稳定的流率倒出瓶子中1/3 的饮料。
为此,公开号为CN102838076A的专利文献公开了一种具有压力平衡系统的饮料分配器,其用于与装有液体饮料的倒置的瓶子相配合使用,包括:一个封盖组件,其包括一个用于与瓶子的瓶口接合的封盖、一个用于分配所述液体饮料的分配管、一个具有单向阀的通气管;以及一个饮料阀,其设在所述分配管的出口处,所述饮料阀可被用户操作以从所述瓶子分配所述液体饮料。当所述封盖组件与瓶子的瓶口接合时,所述单向阀允许环境空气进入瓶子,而不允许装在瓶子内的液体饮料和/ 或气体通过该单向阀流出。采用单向阀进气结构,理论上来说可以根据瓶子内外的压力差进行自动开闭以保证液体稳定流出,但是在实际使用中,分配管的液体流量仍不够稳定,单向阀通气管处大都存在液体渗漏,这样就增加了分配器的清洁消毒难度。
此外,现有瓶装液体分配器普遍存在分配管路长、结构复杂并安装在分配器内部不可拆卸的问题,这些都导致清洁、消毒不便利及成本高。尤其是在干旱缺水的地方,不方便清洗、消毒,这会直接影响饮用者的安全。
技术问题
为了解决上述的技术问题,本发明的目的之一是提供一种瓶装液体分配器的阀总成,出液流速稳定连续,并且进气管路和出液管路采用可拆卸更换设计,更加卫生安全,适合缺水地区使用。

作为优选,所述分配管总成插入阀体的分配管安装孔内时,其封盖嵌入阀体上端凹槽后实现限位,一阀盖螺纹连接固定在阀体上端从而将分配管总成及其封盖固定在阀体上,阀盖具有能够露出封盖的接合部的通孔,封盖和阀体通过定位块、定位槽配合定位从而限制封盖转动。
作为优选,所述阀体操纵机构包括拉杆,拉杆插装在阀座上的拉杆安装孔内,拉杆安装孔与阀体安装孔垂直连通,拉杆上套设拉杆弹簧和拉杆螺母,拉杆弹簧一端与拉杆相抵,拉杆弹簧另一端与拉杆螺母相抵,拉杆螺母与阀座螺纹连接固定,所述压盘穿出压盘螺母后与拉杆连接,拉杆穿出拉杆螺母后与把手活动连接,把手通过拉杆销与拉杆铰接,在拉杆弹簧的作用下,把手的头部与拉杆螺母相抵。
进一步优选,所述拉杆上设有T形插槽,压盘上设有能够与T形插槽上下插接的插头,当阀体自上而下插入阀座的阀体安装孔内时,压盘上的插头插入拉杆的T形插槽内。进一步优选,所述拉杆和阀体均通过导向结构与阀座配合插接。
作为优选,所述阀座下端套设有能够遮蔽阀体安装孔的护罩。

2)分配管总成、阀体和阀座装配简易、操作使用方便,并且可单手操作实现更换分配管总成;普通阀更换时需要双手操作,有时要借助工具;
3)放饮料时,饮料只与分配管总成件内壁接触,不会与阀的其他部件接触,保证卫生安全;
4)分配管总成件可为一次性使用件,每天淘汰,省去了清洗和消毒过程,特别适用于缺水条件的地区;市场上其它阀都需要清洗、消毒处理,对用户使用不方便,且维护成本高,特别是缺水的地方,消毒无法保证。

实施例1:
如图1所示的一种瓶装液体分配器的阀总成,包括阀座10、阀体20和分配管总成30。
如图2、图3、图4所示,所述阀座10具有阀体安装孔101和拉杆安装孔102,阀体安装孔101上下贯通,所述阀体20自上而下插装在阀体安装孔101内。拉杆安装孔102与阀体安装孔101垂直连通,拉杆安装孔102内插装拉杆11,拉杆11上套设拉杆弹簧12和拉杆螺母13,拉杆弹簧12一端与拉杆11相抵,拉杆弹簧12另一端与拉杆螺母13相抵,拉杆螺母13与阀座10螺纹连接固定,这样拉杆弹簧12赋予拉杆11向内插入运动的趋势;拉杆11内端与阀体20连接,拉杆11外端穿出拉杆螺母13后与把手15活动连接,把手15通过拉杆销14与拉杆11铰接,在拉杆弹簧12的作用下,把手15的头部与拉杆螺母13相抵,把手15头部的弧形边缘与拉杆销14的距离逐渐增大,当把手15绕拉杆销14转动时,把手15的头部与拉杆螺母13相抵的抵接点到拉杆销14的距离增大,从而能拉动拉杆11向外运动,这样,把手15和拉杆11等就构成开启和关闭阀体20的阀体操纵机构。本实例中,在把手15的外端安装有按扣16,所述阀座10下端套设有能够遮蔽阀体安装孔101的护罩18。为了能够将阀座10安装在瓶装液体分配器的支承部件的阀座安装孔内,在阀座10上设有凸缘,在阀座10上部螺纹连接有阀座盖17,这样在阀座10上部插入安装孔内时,可通过阀座盖17和凸缘实现上下限位固定。
如图4、图5所示,所述阀体20具有分配管安装孔201和压盘安装孔202,分配管安装孔201上下贯通,分配管总成30自上而下插装在分配管安装孔201内。压盘安装孔202与分配管安装孔201垂直连通,压盘安装孔202内插设压盘21,压盘21上套设压盘弹簧22和压盘螺母23,压盘弹簧22一端与压盘21相抵,压盘弹簧22另一端与压盘螺母23相抵,压盘螺母23与阀体20螺纹连接固定,压盘21的外端穿出压盘螺母23后与拉杆11内端连接。所述阀体20与阀座10采用可拆卸方式插接,为了方便拆装配合,拉杆11内端设有T形插槽,而压盘21的外端设有能够与T形插槽上下插接的插头,当阀体20自上而下插入阀座10的阀体安装孔101内时,压盘21的外端插头插入拉杆11内端的T形插槽内,这样按动把手15即可通过拉杆11向外拉动压盘21,达到开闭阀体效果。为了确保压盘21与拉杆11能够配合插接,避免因为拉杆11的转动或者阀体20的转动而导致插接难度增加,拉杆11和阀体20均通过导向结构(如导向筋、槽或成型连接配合等)与阀座10配合插接,这样就限制了拉杆11在阀座10的拉杆安装孔102内转动,也限制了阀体20在阀座10的阀体安装孔101内转动。本实施例中,仅是通过阀体20上端的凸缘实现阀体20的插入限位,而对阀体20拔出不做限位固定,这样当瓶子内液体分配完成时,直接可以将阀体20连同瓶子一起取出,拆装操作更加方便。
如图6、图7、图8所示,分配管总成30包括一封盖301,封盖301具有用于与瓶子的瓶口接合的接合部305(本实施例中为内螺纹,与瓶子瓶口的外螺纹连接),所述封盖301的底部壁上开有一通气孔306和一出液孔307;一通气管302连接至通气孔306,一分配管303连接至出液孔307,通气管302和分配管303下部各连接有一软管32。为了确保通气孔306进气与出液孔307出液互不干扰,所述通气孔306的孔径为1~3mm,所述出液孔307的孔径大于6mm,并且分配管303及其下部软管32的总长度大于40mm。本实施例中,所述通气孔306的孔径为1.3mm左右,所述出液孔307的孔径为6mm左右,分配管303及其下部软管32的总长度为120mm左右,所述通气孔306和出液孔307的孔间距大于5mm。所述封盖301呈瓶盖状,所述接合部305为设在封盖内侧壁上的内螺纹,与瓶子瓶口的外螺纹配合连接。所述通气管302、分配管303和封盖301一体成型,软管32、通气管302和分配管303的管径均与出液孔307的孔径相一致。所述软管32为硅胶管,两根软管32分别套设在通气管302和分配管303的下端,软管32与通气管302、分配管303的接合处套设管箍31紧固并通过超声波铆接固定,套设在两个软管32外面的两个管箍31一体成型,这样将通气管302和分配管303并排连为一体,能够方便的将分配管总成30插入阀体20的分配管安装孔201内。材料选用食品级PE及硅胶管,符合食品卫生条件,分配管、通气管与硅胶管经管箍超声波铆接固定,能承受碳酸饮料产生的高气压。当分配管总成30插入阀体20的分配管安装孔201内时,两个软管32能够被阀体20上的压盘21的内端所挤压,压盘21的内端挤压面应与其对应位置的分配管安装孔201内壁相贴合从而使得挤压变形后的两个软管32能够被封闭。分配管总成30插入阀体20的分配管安装孔201内时,其封盖301嵌入阀体20上端凹槽后实现限位,一阀盖24螺纹连接固定在阀体20上端从而将分配管总成30及其封盖301固定在阀体20上,阀盖24具有能够露出封盖301的接合部305的通孔以使其能够与瓶子的瓶口连接,封盖301和阀体20通过若干定位块304、定位槽配合定位从而限制封盖301转动,这样确保封盖301能够与瓶子的瓶口紧密结合连接,本实例中,在封盖301的外周上设置了多个定位块304,定位块304的作用不仅用于与阀体20上的定位槽配合限制封盖301转动,而且用于与阀盖24配合固定分配管总成30及封盖301。为了进一步确保封盖301与瓶子的瓶口紧密结合连接,在封盖301的底部壁上设有与现有的瓶盖相同的环形密封凸起308,当封盖301与瓶子的瓶口连接时,环形密封凸起308能够封闭瓶口壁与封盖301的接合处从而避免渗漏。
一种瓶装液体分配器,包括至少一个能够安装上述阀总成的支承部件。阀座10安装在支承部件的阀座安装孔内,使用时,将阀体20从阀座10上拔出,将新开启的饮料瓶子的瓶口与阀体20内的封盖301紧密连接,此时,阀体20上的压盘21在压盘弹簧22作用下压紧分配管总成30中的两个软管32,实现自动封闭,瓶子内的液体无法流出,将瓶子倒置,将连接在瓶子上的阀体20插入阀座10的阀体安装孔101内,压盘21外端的插头与拉杆11内端的T形槽插接,这样,按动把手15通过拉杆11向外拉动压盘21即可使得两个软管32被打开释放,瓶子内的液体即可沿出液孔307、分配管303及其软管32流出,外部气体沿通气管302及其软管32、通气孔306进入瓶子内部,从而瓶子内的液体能够连续顺畅的流出;当暂时不需要分配液体时,可用护罩18套在阀座10下端的开口上,避免昆虫、灰尘进入;当需要更换分配管总成时,将瓶子从阀体20上取下,旋去阀盖24,按动把手15通过拉杆11向外拉动压盘21即可使得两个软管32释放,取出旧的分配管总成30,换上新的分配管总成30,再旋上阀盖24即可。
本发明具有下述优点:
1)分配管采用双管结构——通气管和出液管分开,放饮料时,当瓶内气压与外界有压力差时,气管进气,确保出液连续,流速快而稳定。分配管总成、阀体和阀座装配简易,更换时可单手操作;
2)分配管总成件为一次性使用件,每天淘汰,省去了清洗和消毒过程,特别适用于缺水条件的地区;
3)分配管与饮料瓶瓶盖螺纹一致,与饮料瓶密封可靠;
4)放饮料时,饮料只与分配管总成件内壁接触,不会与其他部件接触,保证卫生安全;
5)分配管总成件能承受100Psi压力持续 60秒不破裂、不漏液、不漏气;
6)流速稳定,放200ml饮料所需时间为8~10秒;
7)把手结构功能,上抬能够停留在90度位置,使操作者可以单手完成安装和取出阀体、更换分配管总成件的动作;
8)把手按压力<30N,操作省力。
需要强调的是:以上仅是本发明的较佳实施例而已,并非对本发明作任何形式上的限制,凡是依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明技术方案的范围内。
