实施例1
如图1至图6所示，本实施例所公开的开关阀100包括：阀体10、第一膜片20、第二膜片40以及阀芯机构30。
阀体10包括下阀体11以及对接于下阀体11的上方的上阀体12，上阀体12与下阀体11的对接区域的内部形成压力腔19。在下阀体11两侧形成有进水口13和出水口14，下阀体11的中部形成有由筒状体结构的分隔部件161形成的内环腔16，该内环腔16的底部与出水口14的内端连通，内环腔16的上端形成为阀孔17。内环腔16的外围形成有外环腔18，进水口13的内端贯通至外环腔18。如此，如图1所示，液体可通过进水口13流入外环腔18，并可从阀孔17的顶部进入到内环腔16，随后可从出水口14流出。
第一膜片20设置于阀孔17的上方，并径向的覆盖至外环腔18，优选地，可通过将第一膜片20的边缘夹持于上阀体12与下阀体11的对接处而实现对第一膜片20的安装，压力腔19位于第一膜片20的上方。该第一膜片20具有可变形的特点，具体地，如图2所示，可通过向下压迫第一膜片20而使得第一膜片20借由靠近边缘区域或整体区域的变形封堵阀孔17，并且，如图1所示，在撤销对第一膜片20向下的压迫后，从进水口13进入到外环腔18的液体能够将第一膜片20借由其靠近边缘区域变形或整体区域的变形而向上顶起而使阀孔17打开。可选用具有一定弹性且柔性的鼓膜作为第一膜片20。
第一膜片20与外环腔18对应的区域设置有平衡孔21，优选地，使平衡孔21设置在靠近进水口13的内端区域；第一膜片20与阀孔17对应的区域设置有受控孔22，该受控孔22由穿设第一膜片20并向上凸出于第一膜片20的管体23的顶部形成。
上阀体12的顶部具有液控口15，该液控口15可由安装于上阀体12的顶部的接头形成，第二膜片40设置于液控口15的下方。
如图1和图2所示，阀芯机构30设置于上阀体12中，并介于第一膜片20和第二膜片40之间。具体地，该阀芯机构30包括直动阀芯31和作动部件。上阀体12的内部开设有导向腔，该导向腔向下贯通至压力腔19，向上贯通至第二膜片40下方的腔室，直动阀芯31设置于导向腔中，该直动阀芯31的下端设置有弹性塞与第一膜片20的中部的管体23所形成的受控孔22相对，直动阀芯31通过向下运动而能够使得弹性塞封堵受控孔22并压迫第一膜片20，以随后带动第一膜片20封堵阀孔17，而在直动阀芯31向上运动以撤销对受控孔22的封堵以及撤销对第一膜片20的压迫后，如图1所示，来自进水口13的液体进入到外环腔18而对第一膜片20实施向上的推力，进而使得第一膜片20通过向上变形而将阀孔17打开。优选地，在第一膜片20上设置有限位板24，在第一膜片20向上变形时，限位板24通过与压力腔19的顶部止挡而限制第一膜片20对阀孔17的打开量（或称开度）。
液控口15用于引入液体而通过第二膜片40对直动阀芯31的上端进行施压，而使直动阀芯31朝下运动而实施对受控孔22封堵以及随后对第一膜片20的压迫。
作动部件用于为直动阀芯31提供复位力，而使得直动阀芯31在解除被液控口15的液体驱动后而向上运动至复位状态，进而撤销对受控孔22的封堵以及对第一膜片20的压迫。作动部件可以为分别设置于上阀体12以及直动阀芯31中的磁体322,321，该两个磁体322，321可通过磁斥力或磁引力为直动阀芯31提供复位，例如，如图1和图2所示，位于直动阀芯31中的磁体321的下端与位于上阀体12中的磁体322的上端磁极同极相对，这使得两个磁体322，321之间形成磁斥力，直动阀芯31利用磁斥力复位。再例如，如图6所示，位于直动阀芯31中的磁体322以及位于上阀体12中的磁体321异性磁极朝向相同（或者使其中一个为磁体，另一个为磁钢片），且位于直动阀芯31中的磁体321与位于上阀体12中的磁体322保持在高度上相对的位置，如此，上阀体12中的磁体322对直动阀芯31的磁体321之间形成磁引力，以带动直动阀芯31向上运动而复位。
如图4和图5所示，作动部件还可以是弹簧34，该弹簧34设置在直动阀芯31的顶部台阶与上阀体12的台阶之间，在液控口15的液体撤销对直动阀芯31驱动后，该弹簧34复位而带动直动阀芯31向上运动而复位。
如图1和图2所示，在液控口15处的液体通过第二膜片40驱动直动阀芯31时，第二膜片40会适应性的产生变形并使得其下方的腔室容积减小，为避免第二膜片40下方的液体因无法排出而产生抗力，在导向腔的腔壁与第二膜片40的下方的腔室之间开设气体排泄通道33，并且，直动阀芯31在未受驱而处于高位时，其上的密封圈312位于气体排泄通道33的下端口的上方，而在直动阀芯31受驱后处于低位时，密封圈312位于该下端口的下方。如此，在直动阀芯31受驱向下运动过程中，气体排泄通道33始终打开而将第二膜片40的腔室内的气体排入下阀体11的压力腔19中以避免该腔室内的气体产生抗力，而在直动阀芯31运动至最低位过程中先封堵受控孔22，随后压迫第一膜片20封堵阀孔17后，直动阀芯31的密封圈312将气体排泄通道33与压力腔19隔离，进而避免压力腔19内的液体通过气体排泄通道33上流。
第二膜片40可以为具有一定弹性和柔性的鼓膜，也可以为具有一定弹性和刚性的簧片。
如图1和图2所示，若第二膜片40为鼓膜，则使得第二膜片40上方的接头的底部设置成球形面，并将直动阀芯31的顶部311也设置成球形面。当液控口15处的液体压力不足以驱动直动阀芯31时，在作动部件的作用下，直动阀芯31向上推抵第二膜片40而使得第二膜片40处于张紧状态，而当液控口15处的液体驱动直动阀芯31时，第二膜片40变形而褶皱。
如图3所示，若第二膜片40为簧片，该簧片构造成在自由状态下呈向上凸出的拱形，直动阀芯31的顶部311配置成锥形结构且在中心位置形成顶针或球体结构。并且，簧片的拱形区域受驱于压力液体而朝反向变形（向下变形），限位环41用于限制簧片的变形程度以使得簧片解除受驱后能够复位。当液控口15处的液体压力达到足以能够使簧片的拱形区域向下变形并克服作动部件时，液体压迫簧片向下变形，该簧片向下变形时推抵直动阀芯31向下运动而使得直动阀芯31封堵受控孔22并压迫第一膜片20。而在液体压力不足以维持变形时，簧片受限位环41限制而自动复位，作动部件使得直动阀芯31复位。
对于使用簧片作为第二膜片40的情况，液体压力在驱动阀芯机构30前首先需要能够驱动簧片变形，可通过计算和多次实验来获得簧片向下变形所需的液体压力。因而，利用簧片作为第二膜片40需要使液体压力满足预设的压力阈值才能够驱动阀芯机构30动作，进而避免阀芯机构30误动。
下面介绍一下本实施例所提供的开关阀100的工作过程：
该开关阀100通过进水口13和出水口14连接在管路中， 自其它管路引出一液控管路而连接至开关阀的液控口15。
如图1所示，若来自液控管路的液体压力不足以驱动阀芯机构30封堵受控孔22而随后压迫第一膜片20时，开关阀所在管路内的液体会通过开关阀100的进水口13流入开关阀100的外环腔18，并将第一膜片20向上顶起，而使阀孔17处于打开状态，液体随后进入到阀孔17并从出水口14流出，部分液体通过平衡孔21流入压力腔19内并从受控孔22流出而随后也从出水口14流出，此时，开关阀100处于打开状态。如图1所示，在限位板24靠近平衡孔23的侧壁上开设有槽口241以使得液体也能够进入限位板24所包络的内部腔。
如图2所示，若来自液控管路的液体的压力上升至能够驱动阀芯机构30的程度，开关阀100的液控口15处的液体驱动阀芯机构30而使阀芯机构30封堵受控孔22并随后压迫第一膜片20，这使得第一膜片20关闭阀孔17，如此，从开关阀100的进水口13流入外环腔18的液体不能通过阀孔17，而只能通过平衡孔21入到压力腔19，由于受控孔22被封堵，进入压力腔19的液体在压力腔19中建立压力以与阀芯机构30共同向下压迫第一膜片20，进而使得开关阀100关闭。由于压力腔19内的液体也对第一膜片20进行压迫，因而，液控口15处的液体压力以及开关阀100所在的管路内的液体的压力出现一定的降低或波动也不会使得阀孔17打开。因而，本实施例所提供的开关阀100还具有在对阀孔17的锁死功能。
本实施例所提供的开关阀100的优势在于：
1、无电源时依靠其他管路液体的压力能够控制开关阀所在管路中的液体的通断。
2、能够实现不同类型及不同浓度的液体间混合时，择一性的打开或关闭，进而联动其他液体的通断。
3、能够实现不同类型及不同浓度的液体间流动控制时，择一性的打开或关闭，进而联动其他液体的通断。
4、开关阀具有锁死功能，避免液体压力波动时开关阀出现泄漏。
5、采用簧片作为第二膜片，使得液体压力满足预先设定的压力阈值时，再打开或关闭开关阀，进而避免了开关阀内部阀芯机构误动。
6、选用磁体作为作动部件，这使得对阀芯机构的力的作用不会因为长期使用而失效，进而提高了开关阀的使用寿命。
本发明的实施方式
实施例2
如图7至9所述，本实施例所提的开关阀100’的关于上阀体12、下阀体11的内部构造、第一膜片20、第二膜片40的结构类型、作用以及设置方式均与实施例1一致，本实施例与实施例1的主要区别在于阀芯机构的结构。
在本实施例中，阀芯机构30’包括主动部件、从动阀芯31’、第一作动部件以及第二作动部件、以及限位筒35’。从动阀芯31’所在的径向位置与实施例1的直动阀芯31的位置相同，即，位于第一膜片20的上方且下端朝向第一膜片20的受控孔22。限位筒35’固定的设置在从动阀芯31’外，该限位筒35’的顶部封闭以用于限制从动阀芯31’向上运动时的最高位置，优选地，主动部件被构造成套筒34’，套筒34’的顶部封闭，且构造成适合被第二膜片40驱动的构造，即顶部341’构造成与实施例1中的直动阀芯31的顶部311一致的构造。
套筒34’套设在限位筒35’外，第一作动部件设置在套筒34’与从动阀芯31’之间，该套筒34’作为被液控口15处的液体驱动的直接受驱部件，在套筒34’受驱时，套筒34’通过第一作动部件驱动从动阀芯31’在相同方向上运动。
该第一作动部件包括分别设置在从动阀芯31’与套筒34’中的第一磁体321’和第二磁体322’，并使得两个磁体的同性磁体朝向相同，如此，套筒34’受到液控口15的液体驱动时能够带动从动阀芯31’同向运动，以实现在套筒34’受驱时套筒34’通过第一作动部件带动从动阀芯31’向下运动，以封堵受控孔22并随后压迫第一膜片20。
第二作动部件设置在套筒34’与上阀体12之间，该第二作动部件用于为套筒34’提供向上的复位力，以当套筒34’解除液控口15处的液体的驱动时，第二作动部件驱动套筒34’向上运动而复位，在套筒34’复位过程中，套筒34’借由第一作动部件而带动从动阀芯31’向上运动而撤销对受控孔22的封堵以及第一膜片20的压迫。该第二作动部件可以是分别设置在套筒34’和上阀体12中通过磁斥力或磁引力驱动套筒34’向上运动复位的磁体，或者如图7和图8所示的设置在套筒34’与上阀体12之间的弹簧36’。
在上阀体12中还开设有自上阀体12的内部腔室贯通至上阀体12外的排气孔33’，该排气孔33’用于在第二膜片40向下变形时排出气体以避免内部腔室的气体对第二膜片40的变形产生抗力。
本实施例所提供的开关阀100’从整体的功能上与实施例1相同，区别主要在于阀芯机构30’内部部件及动作关系上，下面简单介绍一下本实施例所提供的开关阀100’的工作过程：
当液控口15处的液体达到一定压力时，液体借助第二膜片40（该第二膜片40可以为鼓膜，也可以为簧片，其作用与实施例1相同）驱动套筒34’，套筒34’向下运动，套筒34’借助于第一作动部件所产生的磁引力（图7和图8所展示的为磁引力）而带动从动阀芯31’向下运动，如图8所示，并最终使得从动阀芯31’封堵受控孔22并随后压迫第一膜片20，而后，借由平衡孔21，压力腔19内充满液体而对第一膜片20也进行压迫。
当液控口15处的液体解除对套筒34’的驱动时，第二作动部件为套筒34’提供复位，在套筒34’复位过程中，套筒34’通过第一作动部件带动从动阀芯31’向上运动，如图7所示，从而撤销对第一膜片20的压迫，进而使得从进水口13流入阀体内的液体能够将第一膜片20打开。
本实施例所提供的开关阀100’具有与实施例1所提供的开关阀100相同的功能，可应用于相同的场景。
实施例3
本实施例所提供的开关阀100’’与实施例2所提供的开关阀100’关于阀体、第一膜片20、第二膜片40以及阀芯机构的结构形式一种，所不同的是第一作动部件使得套筒34’与从动阀芯31’之间的相对运动关系发生了改变，这一改变使得本实施例所提供的开关阀100’’与实施例1、实施例2所提供的开关阀的功能产生了差异。
如图10和图11所示，在本实施例中，第一作动部件的第一磁体321’和第二磁体322’的同性磁极朝向相同，在套筒34’解除受驱后，第一磁体321’低于第二磁体322’以使得套筒34’对从动阀芯31’施加磁斥力而迫使从动阀芯31’压迫第一膜片20，而在套筒34’受驱于压力液体而移动过程中，套筒34’带动第二磁体322’移动并通过限位筒35’对从动阀芯31’的限制而使得第二磁体322’低于第一磁体321’而使得套筒34’对从动阀芯31’施加反向的磁斥力，从动阀芯31’受驱于反向磁斥力而撤销对第一膜片20的压迫；第二作动部件也是用于使套体复位的弹簧36’以用于使套筒34’复位。
从套筒34’与从动阀芯31’的动作关系上看，套筒34’与从动阀芯31’受到第一作动部件与第二作动部件的配合驱动而产生相反的位置关系。即，如图10所示，当套筒34’未受驱而处于高位时，套筒34’借由第一作动部件迫使从动阀芯31’处于封堵受控孔22并随后压迫第一膜片20的低位，如图11所示，而当套筒34’受驱后而处于低位时，套筒34’借由第一作动部件以及限位筒35’的限位作用而迫使撤销对受控孔22的封堵及对第一膜片20的压迫而切换至高位。
由于本实施例所提供的开关阀100’’的阀芯机构30’’的受驱状态与第一膜片20的受压状态的关系与实施例1、2所提供的阀芯机构的受驱状态与第一膜片20的受压状态的关系完全相反，进而导致本实施例所提供的开关阀100’’的功能与实施例1、实施例2所提供的开关阀不同。
本实施例所提供的开关阀100’’的特点是当液控口15处的液体压力升高至能够驱动阀芯机构30’’时，阀芯机构30’’将开关阀100’’的阀孔17打开，进而使开关阀100’’打开，而当液控口15处的液体压力较低而无法驱动阀芯机构30’’动作时，阀芯机构30’’保持压迫第一膜片20而使开关阀100’’保持截断状态。因而，本实施例所提供的开关阀100’’具有可在管路内的液体压力低时将管路关闭。另外，本实施例所提供的开关阀100’’利用液体控制相关关联通断也具有与实施例1、2一致的优势。即，均可不需要电力，并可实现管理通断的联动。
本实施例所提供的开关阀与其他实施例的开关阀不同的优势在于：
在液体压力不足时开关阀关闭，进而阻断液体的流动，进而保护了管路系统中的部件的正常工作。
