Description

发酵槽的阀体 技术领域
本申请有关于一种阀体，尤指一种发酵槽的阀体。
背景技术
一般来说，发酵槽的出料口会设置阀体来控制发酵产物能否被排出，而阀体有多种类型，其中，球阀时常被运用于此，更明确来说，球阀包含一本体、一球体与一转动机构，该球体设于该本体中而能被该转动机构带动转动，该球体开设有一流道，当流道与出料口连通，则发酵产物可被排出，而当流道与出料口错开不连通，则发酵产物不被排出，借此达到开关的效果。
然而，发酵产物通常不仅仅是清澄的液体，更包含了残渣等固态物，这些固态物容易在球体转动时被球体带入本体与球体之间的间隙，日久则有发臭甚至腐败生菌的可能，进而污染通过球阀的发酵产物，成为卫生上的极大问题。
此外，每次发酵制程完成后，发酵槽须进行清洗与消毒，为了排出清洗的废液，球阀会设为开启状态，此时，清洗液根本无法深入球体与本体之间的间隙，无法对球阀内部进行完整的清洗。
若要彻底清洗球阀，就必须将球阀整个拆下并拆解，十分麻烦，更使整个发酵制程无法连续进行，造成效率较低、制程拉长。
至于其他形式的阀体，同样会有需拆下进行清洗的困扰，亦不利连续封闭生产的系统。
因此，如何避免阀体内部的藏污纳垢，并便于清洗又不污染发酵槽，实为亟需解决的问题。
发明内容
本申请的主要目的在于提供一种发酵槽的阀体，便于清洗阀体内部而无须将阀体拆下，亦利于清洗前端发酵槽而不污染后端发酵槽。
为达成上述目的，本申请提供一种发酵槽的阀体，包含一本体、一阀片、一转动机构、一排液管道与一排液阀；
该本体围构一容室，该本体相对两端分别形成一入口与一出口，该入口与该出口分别与该容室连通且联机定义一轴向，该本体于该入口与该出口之间适当处定义一基准面，该本体于该入口与该基准面之间的壁面开有一排液口；该阀片可转动地设于该本体的容室的基准面处，该阀片能于一关闭位置与一开启位置之间转动，当该阀片位于该关闭位置时，该阀片与该基准面重合而将该容室的环壁彼此密合，使该入口与该出口彼此不连通，当该阀片位于该开启位置时，该阀片与该基准面不重合而与该容室的环壁之间产生间隙，使该入口与该出口彼此连通；该转动机构设于该本体而与该阀片连接，该转动机构用以控制该阀片于该关闭位置与该开启位置之间转动；该排液管道一体形成于该本体的外壁而与该排液口连通；该排液阀设于该排液管道以控制该排液管道连通外界与否；其中，该容室于该基 准面处的内径定义为R，该排液口至该基准面沿该轴向的距离定义为D，D小于R的两倍。
可选地，该本体包含一第一部分与一第二部分，该第一部分与该第二部分彼此组合而形成该本体，该基准面位于该第一部分与该第二部分的交界处。
可选地，其中D小于R。
可选地，该阀片径向上的两端分别枢设至该本体，该阀片的转轴垂直于该轴向。

具体实施方式
以下仅以实施例说明本申请可能的实施态样，然并非用以限制本申请所欲保护的范畴，合先叙明。
请参考图1至图4，本申请提供一种发酵槽的阀体，包含一本体10、一阀片20、一转动机构、一排液管道40与一排液阀50。
该本体10围构一容室11，该本体10相对两端分别形成一入口12与一出口13，该入口12与该出口13分别与该容室11连通且联机定义一轴向，该本体10于该入口12与该出口13之间适当处定义一基准面，该本体10于该入口12与该基准面之间的壁面开有一排液口14；该阀片20可转动地设于该本体10的容室11的基准面处，该阀片20能于一关闭位置与一开启位置之间转动，当该阀片20位于该关闭位置时，该阀片20与该基准面重合而将该容室10的环壁彼此密合，使该入口12与该出口13彼此不连通，当该阀片20位于该开启位置时，该阀片20与该基准面不重合而与该容室11的环壁之间产生间隙，使该入口12与该出口13彼此连通；该转动机构设于该本体10而与该阀片20连接， 该转动机构用以控制该阀片20于该关闭位置与该开启位置之间转动；该排液管道40一体形成于该本体10的外壁而与该排液口14连通；该排液阀50设于该排液管道40以控制该排液管道40连通外界与否；其中，该容室11于该基准面处的内径定义为R，该排液口14至该基准面沿该轴向的距离定义为D，D小于R的两倍，较佳地，D小于R；此外，该排液口14的内径较佳地为该容室11内径的一半以下。
于本实施例中，该本体10包含一第一部分101与一第二部分102，该第一部分101与该第二部分102彼此组合而形成该本体10，该基准面位于该第一部分101与该第二部分102的交界处；该阀片20径向上的两端分别枢设至该本体10，该阀片20的转轴垂直于该轴向；该转动机构包含一L形的把手30，该把手30的一端连接至该阀片20。
关于该排液阀50，可采用任何型式的适当阀体，于本实施例中，该排液阀50包含一外壳51与一阀件52，该外壳51围构一内腔511且于该外壳51的轴向一端形成一开口512，该开口512与该排液管道40连通，该外壳51的侧壁开有一排放口513，该开口512与该排放口513的开设方向彼此垂直，该阀件52可沿该外壳51轴向滑移地部分设于该内腔511中，该阀件52能沿该外壳51的轴向滑移以选择性地封止该开口512。
实际使用时，本申请提供的发酵槽的阀体通常设置于一发酵槽的下端出料口处，并以该入口与该发酵槽连通，而该出口则连通至另一发酵槽或通往其他制程的管道，形成一封闭连续的制造流程，欲使上方的发酵槽的发酵产物流出时，则在该排液阀关闭的前提下，转动该转动机构以将该阀片转动至该开启位置，发酵产物便能经由该容室通往该出口而不会自该排液口流出，而若要进行容室内部的清洗，则先转动该转动机构以将该阀片转动至该关闭位置，并开启该排液阀，再由该入口注入水或清洁液体进行冲洗，而冲洗过后的废液可经由该排液口与排液管道排出，如此可确保该出口及其连接的发酵槽不被清洗液体污染，至于若要一次清洗阀体内部与下方发酵槽时，则使阀片维持于开启位置，并开启排液阀，便能同时进行冲洗。
特别要说明的是，该排液口距离该阀片的距离不会过长，使得排液口与阀片之间的空间被清洗过后的废液易于从排液口排除，而不会积于阀片处。
工业实用性
借由上述结构，本申请提供的发酵槽的阀体能在不拆下的前提下进行阀体内的清洗，且清洗废液能独立排出而不会污染所连接的发酵槽，且清洗无死角，效果良好，重要的是，结构极为简单，易于操作且不易藏污纳垢，且可以在工业中制造和使用，具备工业实用性。
