分流器组件、阀箱和柱塞泵
交叉引用
本发明要求在2022年08月15日提交中国专利局、申请号为202210974401.1、发明名称为“分流器组件、阀箱和柱塞泵”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请涉及油气开采设备技术领域，尤其涉及一种分流器组件、阀箱和柱塞泵。
背景技术
柱塞泵是油气开采过程中的一种重要的设备，柱塞泵通常包括液力端和动力端，动力端可以将动能通过减速传动系统等传递至液力端，液力端内部的高压液体产生的力通过柱塞等零部件作用至动力端壳体。在一些情形下的柱塞泵中，通常设有上凡尔总成和下凡尔总成。在动力端驱动柱塞向远离液力端的方向运动时，上凡尔总成关闭，下凡尔总成打开，完成进液动作，在动力端驱动柱塞向靠近液力端的方向运动时，下凡尔总成关闭，上凡尔总成打开，完成排液动作。
由于在一些情形下的柱塞泵中，上凡尔总成和下凡尔总成沿垂直于柱塞的轴向的方向分布，使得柱塞泵中的阀箱中的开孔呈十字相贯状分布，用以为柱塞提供活动空间的轴向孔和用于安装上凡尔总成和下凡尔总成的径向孔之间容易在液体流动时出现应力集中现象，且应力较大的位置位于交变区，使得阀箱的相贯线位置处容易产生疲劳裂纹，进而出现阀箱损坏的情况，严重影响阀箱和柱塞泵的使用寿命。

以下结合附图，详细说明本申请各个实施例公开的技术方案。
如图1所示，本申请实施例公开一种分流器组件，该分流器组件可以应用在柱塞泵中。具体来说，柱塞泵还包括阀箱500和柱塞710，阀箱500设有内腔510、进液通道520和排液通道530，分流器组件可以安装在阀箱500的内腔510中，且分流器组件与阀箱500的进液通道520和排液通道530均连通，分流器组件与柱塞710配合，柱塞710与柱塞泵中的动力端传动连接，以在动力端的驱动下，使柱塞710在阀箱500的内腔510中作往复运动，以使分流器组件在进液过程和排液过程之间循环切换(如图15和图16所示)。 当然，柱塞泵中还包括压盖720、压帽730和盘根总成740等部件，考虑文本简洁，此处暂时不再一一介绍。
如图1～图10所示，分流器组件包括分流器100、第一凡尔体210、第二凡尔体220、第一凡尔胶皮310和第二凡尔胶皮320。其中，第一凡尔胶皮310和第二凡尔胶皮320均用以提供密封作用，为此，二者均可以采用橡胶等弹性相对较好的材料形成，二者的截面形状和尺寸等参数均可以根据实际需求确定，此处不作限定。当然，为了保证第一凡尔胶皮310和第二凡尔胶皮320均可以提供可靠的密封效果，二者均可以为环状结构件。
如图2-图4所示，分流器100设有排液孔110和进液孔120，排液孔110和进液孔120相互间隔。也即，排液孔110和进液孔120均为形成于分流器100上的独立通道，以保证排液过程和进液过程能够互不干涉。另外，分流器100上还可以设有便于拆卸分流器100的拆装螺纹150等结构。
其中，排液孔110连通于分流器100沿自身轴向相背的第一端面和第二端面，也即，排液孔110沿分流器100的轴向贯穿分流器100设置，从而使分流器100相背两端的空间可以通过排液孔110相互连通，排液孔110的截面可以为三角形或矩形等，为了降低液体流动时所受到的阻碍，排液孔110的截面可以为圆形。
进液孔120连通于分流器100的侧面和第一端面，侧面连接于分流器100的第一端面和第二端面之间，从而使分流器100的第一端面与侧面所在的空间可以被进液孔120连通，使得分流器100的侧面周围可以作为进液空间，分流器100的第一端面一侧的空间可以作为液体的暂存空间，分流器100的第二端面一侧的空间可以作为排液空间。
相应地，为了保证分流器组件在被安装至柱塞泵的阀箱500内之后，能够正常地进行进液过程和排液过程，在不受其他因素干扰的情况下，结合图11、图12、图15和图16，可以使进液孔120位于侧面的孔口与柱塞泵的阀箱500的进液通道520连通，且使排液孔110位于第二端面的孔口与阀箱500的排液通道530连通，进而保证液体可以通过阀箱500的进液通道520经进液孔120流入分流器100的第一端面所在侧的空间内，完成进液过程；之后，在进液孔120被封闭的情况下，使暂存于第一端面所在一侧空间内的液体能够自分流器100的排液孔110流向分流器100的第二端面所在一侧的空间，完成排液过程。
当然，为了保证排液过程和进液过程相互独立，需要利用上述第一凡尔体210、第二凡尔体220、第一凡尔胶皮310和第二凡尔胶皮320等部件为分流器100提供封堵作用。具体来说，在进液过程进行时，需要使排液孔110的至少一端的孔口被封闭，且由于排液孔110的一个孔口与进液孔120位于 同侧，以及进液过程和排液过程的切换动力源为沿轴向作往复运动的柱塞710，为此，如图15所示，在进液过程进行时，可以使排液孔110位于第二端面上的孔口被封堵；相似地，由于进液过程和排液过程的切换动力源为沿轴向作往复运动的柱塞710，为此，如图16所示，在排液过程进行时，可以使进液孔120位于第一端面上的孔口被封堵。当然，为了保证第一凡尔体210和第二凡尔体220能够在进液过程和排液过程产生相应的位移，如图12所示，二者均可以配设有凡尔弹簧230，且凡尔弹簧230可以安装在弹簧支架240上。
详细地说，用以封堵进液孔120的孔口的部件可以包括上述第一凡尔体210，用以封堵排液孔110的孔口的部分可以为上述第二凡尔体220。当然，为了保证在利用第一凡尔体210封堵进液孔120的孔口的过程中，不会将排液孔110的孔口一并封堵，可以在第一凡尔体210上设置相应的贯通结构。
具体来说，如图7所示，第一凡尔体210设有沿分流器100的轴向贯穿第一凡尔体210的连通孔211(即前述贯通结构)，以在通过第一凡尔体210封堵进液孔120的过程中，利用连通孔211避让分流器100的排液孔110，连通孔211与排液孔110沿分流器100的轴向相对设置，且可以使连通孔211的截面积大于或小于排液孔110的截面积。为了提升排液过程的顺畅性，可以使连通孔211和排液孔110的截面积相差不大，且可以使二者的截面形状相似或相同，以及可以使连通孔211和排液孔110的轴线重合。
如图1所示，第一凡尔体210可启闭地面接触于第一端面，以封堵进液孔120，且连通连通孔211和排液孔110。也就是说，在分流器组件中，第一凡尔体210和分流器100之间具备相对运动的能力，且在第一凡尔体210向靠近分流器100所在的方向运动的过程中，第一凡尔体210可以运动至与分流器100的第一端面面接触的状态，且在这种状态下，使得第一凡尔体210能够通过面接触配合的方式，将进液孔120中位于第一端面的孔口封堵，且保证连通孔211和排液孔110能够通过相互连接的方式形成连通关系，从而利于排液过程的正常进行。
具体来说，第一凡尔体210朝向第一端面的表面中包括用以与第一端面上进液孔120的孔口所在的区域配合的第一部分，且第一凡尔体210朝向第一端面的表面中还包括用以与第一端面上排液孔110的孔口所在的区域配合的第二部分，通过使前述第一部分与第一端面上进液孔120的孔口所在的区域呈仿形设计，且使前述第二部分与第一端面上排液孔110的孔口所在的区域呈仿形设计，即可保证第一凡尔体210在与第一端面形成面接触配合关系时，能够利用第一凡尔体210封堵进液孔120，且连通连通孔211和排液孔110。一种具体地实施例是，第一端面为平面状结构，第一凡尔体210朝向第 一端面的表面亦可以为平面状结构，即可在第一凡尔体210与第一端面面接触时，实现封堵进液孔120，且连通排液孔110与第一凡尔体210背离分流器100的一侧空间的目的。
如图1所示，第二凡尔体220可启闭地面接触于分流器100的第二端面，以封堵排液孔110。也就是说，在分流器组件中，第二凡尔体220和分流器100之间亦具备相对运动的能力，且在第二凡尔体220向靠近分流器100所在的方向运动的过程中，第二凡尔体220可以运动至与分流器100的第二端面面接触的状态，且在这种状态下，使得第二凡尔体220能够通过面接触配合的方式，将排液孔110中位于第二端面的孔口封堵，保证进液过程的正常进行。
具体来说，通过使第二凡尔体220朝向第二端面的表面与第二端面中排液孔110所在的部分呈仿形设计，即可保证第二凡尔体220在与第二端面形成面接触配合关系时，能够利用第二凡尔体220封堵排液孔110。一种具体地实施例是，第二端面为平面状结构，第二凡尔体220朝向第二端面的表面亦可以为平面状结构，即可在第二凡尔体220与第二端面面接触时，实现封堵排液孔110的目的。
同时，为了保证进液孔120和排液孔110被封堵时均具有较高的可靠性，如图1～图6所示，第一凡尔胶皮310可被挤压于第一凡尔体210和第一端面之间，第二凡尔胶皮320可被挤压于第二凡尔体220和第二端面之间。如上所述，第一凡尔体210和第二凡尔体220均具备相对分流器100活动的能力，为此，弹性的第一凡尔胶皮310和第二凡尔胶皮320可以被第一凡尔体210和第二凡尔体220分别挤压于分流器100的第一端面和第二端面。
并且，通过使第二凡尔胶皮320环绕于排液孔110之外，可以在进行进液过程时，保证排液孔110位于第二端面的孔口可以始终被密封，进而保证排液孔110的密封性能相对较高。
如图1所示，第一凡尔胶皮310间隔进液孔120和排液孔110，且使第一凡尔胶皮310环绕于排液孔110之外，从而使得第一凡尔胶皮310在被第一凡尔体210挤压于第一端面的情况下，可以利用第一凡尔胶皮310隔绝进液孔120和排液孔110，保证二者独立运行的可靠性相对较高。
另外，为了保证进液孔120中分别位于第一端面和侧面的孔口之间的隔绝性相对较好，可以利用过盈配合的方式组装分流器100和阀箱500，从而使分流器100的侧面与分流器100的第一端面之间能够形成可靠的隔绝关系。
本申请实施例公开一种分流器组件，其可以被应用在柱塞泵中，且被安装在柱塞泵中的阀箱500内。分流器组件中，分流器100上设有连通自身沿轴向相背的第一端面和第二端面的排液孔110，且分流器100的进液孔120 连通分流器100的第一端面和侧面，进而在利用该分流器100执行进液过程和排液过程时，液体均具有沿分流器100的轴向流动的趋势，从而在与该分流器组件对应的阀箱500的设计加工过程中，如图10、图13和图14所示，使得阀箱500中的交变腔503、低压腔502和高压腔501能够沿某一直线方向(即分流器100的轴向)分布，进而在包括该分流器组件的柱塞泵的工作过程中，可以使液体沿垂直于分流器100的轴向的方向作用于分流器100(和阀箱500)上的力相对较小，甚至为零，这可以防止分流器100和阀箱500出现应力集中的问题，提升阀箱500的使用寿命。
并且，在上述分流器组件中，第一凡尔体210和第二凡尔体220均可以相对分流器100运动，使分流器组件能够在进液状态和排液状态之间切换。同时，在分别进行进液过程和排液过程时，为了保证排液孔110和进液孔120均可以被稳定地封堵，第一凡尔体210和第二凡尔体220均可以通过面接触地方式分别与第一端面和第二端面配合，以为进液孔120和排液孔110分别提供密封作用，保证进液孔120或排液孔110的密封可靠性较高。
进一步地，如图1所示，本申请实施例公开的分流器组件还可以包括第三凡尔胶皮330，第三凡尔胶皮330环绕设置于进液孔120位于第一端面的孔口之外，且第三凡尔胶皮330可被挤压于第一凡尔体210和第一端面之间。也就是说，在第一凡尔胶皮310的外周还设有第三凡尔胶皮330，且第三凡尔胶皮330为环状结构，进液孔120中位于第一端面的孔口被夹设于第一凡尔胶皮310和第三凡尔胶皮330之间。相应地，在第一凡尔体210向靠近分流器100所在的方向运动的过程中，第一凡尔体210亦可以在挤压第一凡尔胶皮310时，一并挤压第三凡尔胶皮330。在第三凡尔胶皮330的作用下，可以隔绝进液孔120中分别位于第一端面和侧面的两个孔口，进一步提升进液孔120的两个孔口之间的隔绝可靠性。
为了保证第一凡尔胶皮310的位置稳定性相对较高，可以设置安装槽用以为第一凡尔胶皮310提供限位作用，具体地，如图1和图17所示，分流器100或第一凡尔体210上可以设置前述安装槽，且可以使安装槽的截面形状与第一凡尔胶皮310中容纳于安装槽内的部分的截面形状和尺寸相同，从而保证安装槽可以为第一凡尔胶皮310提供可靠的容纳安装作用。
相似地，为了保证第二凡尔胶皮320和第三凡尔胶皮330的位置稳定性均相对较高，亦可以为第二凡尔胶皮320和第三凡尔胶皮330对应设置安装槽。具体地，如图1所示，亦可以在分流器100上或第一凡尔体210上设置另一安装槽，以为第三凡尔胶皮330提供容纳安装作用。相应地，可以在分流器100上或第二凡尔体220上设置安装槽，为第二凡尔胶皮320提供容纳安装作用，从而保证第二凡尔胶皮320和第三凡尔胶皮330均具有相对较高 的位置稳定性。
为了进一步提升进液孔120位于分流器100的侧面的孔口的隔绝效果，可选地，如图12所示，本申请实施例公开的分流器组件还可以包括密封圈410，进液孔120位于侧面的孔口沿轴向的相背两侧均设有密封圈410。
也即，分流器100的侧面套设有至少两个密封圈410，且进液孔120位于分流器100的侧面的孔口位于两个密封圈410之间。在这种情况下的，当分流器100组装至阀箱500的内腔510后，可以利用密封圈410密封阀箱500的内腔510的腔壁和分流器100的侧面，进而使进液孔120位于分流器100的侧面的孔口能够被隔绝开，防止需要流入进液孔120内的液体沿分流器100和阀箱500之间的间隙流动至其他区域处。
密封圈410可以采用橡胶等弹性材料形成，密封圈410的尺寸等参数可以根据实际情况确定，此处不作限定。为了降低密封圈410的安装难度，可选地，如图1所示，分流器100的侧面设有多个限位槽140，且可以使多个密封圈410的一部分分别一一对应地容纳于多个限位槽140内。也即，分流器100的侧面设置有相对分流器100的侧面凹陷的限位槽140，密封圈410的一部分通过伸入限位槽140的方式，使得限位槽140可以为密封圈410提供限位作用，多个限位槽140可以分别为多个密封圈410提供限位作用，保证每一密封圈410的被限位效果均相对较好。
如上所述，第一端面可以为平面状结构，为了提升第一端面与第一凡尔体210之间的配合稳定性，可选地，如图4和图17所示，第一端面自内向外呈扩口状结构。也就是说，第一端面中，在分流器100的轴向上，越靠近排液孔110的部分与第二凡尔体220之间的间距越小。对应地，为了保证第一凡尔体210能够与第一端面形成面接触的配合关系，如图7所示，第一凡尔体210为外凸状结构，且沿分流器100的轴向，第一凡尔体210中越靠近连通孔211的部分与第二凡尔体220之间的间距越小，从而使第一凡尔体210能够“伸入”第一端面内，且与第一端面形成面接触的配合关系，进而保证第一凡尔体210和分流器100之间能够在垂直于分流器100的轴向的方向(即分流器100的径向)上形成限位配合关系。
更具体地说，第一端面可以为(近似于)圆台的侧面状结构，相似地，第一凡尔体210的侧面亦可以为(近似于)圆台的侧面状结构，保证第一凡尔体210和第一端面之间能够形成可靠的面配合关系。
可选地，如图4和图10所示，第二端面自内向外呈扩口状结构，且通过使第二凡尔体220具有与第二端面对应的结构，保证二者在形成可靠的面配合关系的同时，还可以使第二凡尔体220与分流器100在垂直于分流器100的轴向的方向上形成限位配合关系。
如上所述，第一端面可以为圆台的侧面状结构，在这种情况下，第一端面被过分流器100的轴线的平面截得的线段为直线段，在本申请的另一实施例中，第一端面亦可以为其他异形结构。可选地，如图19所示，第一端面上设置有凹陷区域，具体来说，可以使第一端面中进液孔120的孔口所在的区域相对第一端面的内缘和外缘均向靠近第二凡尔体220所在的方向凹陷。换句话说，在本实施例中，第一端面中对应于进液孔120的孔口所在的区域被过分流器100的轴线的平面截得的线段可以包括两个相互间隔的弧线段(或直线段)，二者相互间隔的区域即为进液孔120的孔口所在的区域，且两个相互间隔的弧线段自进液孔120的孔口相对分流器100的轴线向外扩张地延伸，且分别连接于分流器100的外缘和排液孔110的侧壁。
在采用这种技术方案的情况下，如图19所示，通过使第一凡尔体210对应的区域呈凸起状结构，可以保证第一端面与第一凡尔体210仍能够形成可靠的面接触配合关系；同时，在采用上述技术方案的情况下，第一端面上的“凹陷结构”可以为第一凡尔体210的安装过程提供一定的导向作用，且使第一端面与第一凡尔体210能够在分流器100的径向上形成限位配合关系，进而提升第一凡尔体210与第一端面之间的配合关系的稳定性。
如上所述，排液孔110位于分流器100的轴线所在的区域，且进液孔120在第一端面上亦设有孔口，为此，进液孔120在第一端面上的孔口可以被看作位于排液孔110的周围。在进液孔120的数量为一个的情况下，进液孔120位于排液孔110的一侧，如图2示，在进液孔120的数量为两个或更多个的情况下，多个进液孔120围绕排液孔110设置，且可以使多个进液孔120均匀且间隔地环绕于排液孔110设置，从而在分流器组件的进液过程中，可以使液体自多个进液孔120均匀地被送入分流器100的第一端面所在的一侧空间，一方面可以提升进液效率，另一方面可以保证第一端面任一位置处的进液速率基本相当，提升分流器组件的工作稳定性。更具体地说，分流器100上的进液孔120的数量可以为两个、三个或更多个，进液孔120的具体数量可以根据进液孔120的孔径和分流器100的直径等参数确定，此处不作限定。
在进液孔120的数量为多个的情况下，可以使每一进液孔120在第一端面上的孔口对应的区域的具体结构互不相同或部分不同。在本申请的另一实施例中，如图2所示，可以使每一进液孔120在第一端面上的孔口对应的区域的具体结构相同，这可以降低第一凡尔体210的形成难度，且降低第一凡尔体210和第一端面之间的组装难度。
如上所述，第一端面上进液孔120所在的区域被过分流器100的轴线的平面截得的两线段可以为弧线段，亦可以为直线段。对应地，第一凡尔体210中用以与第一端面配合的表面被过分流器100的轴线的平面所截得的线段亦 可以对应地包括弧线段或直线段，且分别与第一端面上对应的区域面接触。
如图1所示，在利用第一凡尔体210封堵进液孔120中位于第一端面的孔口的过程中，第一凡尔体210朝向第一端面的表面包括与第一端面接触的部分以及用以封堵进液孔120的部分，两类结构之间相互连接。其中，第一凡尔体210中用以封堵进液孔120的部分被过分流器100的轴线的平面截得的图形包括第一线段，也即，第一线段在第一凡尔体210朝向第一端面的表面中所对应的区域用以封堵进液孔120。
可选地，如图1、图17和图21等所示，第一线段为直线段，且该直线段垂直于进液孔120中位于第一端面的孔口的轴向，在这种情况下，第一凡尔体210可以为进液孔120提供与其出液方向相反的封堵作用力，这使得第一凡尔体210对进液孔120的封堵效果相对较好，提升进液孔120的被封堵效果。
或者，如图19和图20所示，上述第一线段还可以为弧线段，且第一线段的中部沿进液孔120位于第一端面的孔口的轴向向进液孔120的内部凸出设置，从而使第一凡尔体210中用以与进液孔120配合的部分可以提供“瓶塞”类作用，以通过部分伸入进液孔120内部的方式，提升第一凡尔体210对进液孔120的封堵效果。
如上所述，第一凡尔体210和第二凡尔体220均与分流器100面接触，可选地，分流器100可以采用硬度相对较高的金属材料经一体压铸等方式形成，以提升分流器100的使用寿命，且保证第一端面和第一凡尔体210之间，以及第二端面和第二凡尔体220之间的面配合关系始终可以保持相对稳定的状态。
在本申请的另一实施例中，如图22-图25所示，分流器100可以包括基体101和第一耐磨环102，第一耐磨环102可以采用硬度和耐磨性均大于基体101的材料形成。具体地，第一耐磨环102可以采用如氧化锆、镍基碳化钨、钴基碳化钨、碳化钛和氮化硼等硬质合金中的至少一者形成，保证第一耐磨环102具备较强的耐磨性和硬度，且通过使用硬度和耐磨性均相对较小的材料形成基体101，可以降低整个分流器100的生产成本。
在组装基体101和第一耐磨环102的过程中，基体101设有第一容纳槽，第一耐磨环102嵌设于第一容纳槽内，以利用第一耐磨环102与第一凡尔体210面接触，提升分流器100的局部的强度和耐磨性，以在保证分流器100的使用寿命和被密封效果均相对较好的同时，降低分离器的整体成本。
并且，由于进液孔120位于分流器100上，继而，在分流器100包括第一耐磨环102的情况下，如图23-图25所示，进液孔120可以包括第一孔段121和第二孔段122，第一孔段121和第二孔段122相互连通，以保证分流器 100侧面的液体仍能够经第一孔段121和第二孔段122被送入分流器100的第一端面所在的一侧空间。
其中，第一孔段121位于基体101，第二孔段122位于第一耐磨环102，以使第一耐磨环102能够与第一凡尔体210面接触，保证二者之间频繁接触仍具有较长的使用寿命和密封效果。另外，第一孔段121和第二孔段122的直径可以不同，为了提升进液过程的顺畅性，可以使第一孔段121和第二孔段122的直径相同，且使第一孔段121的外缘与第二孔段122的外缘相互对接。
基于上述实施例，相应地，如图22-图25所示，还可以使分流器100包括第二耐磨环103，第二端面的至少一部分位于第二耐磨环103上，且使第二耐磨环103被配置为与第二凡尔体220面接触，从而利用第二耐磨环103作为分流器100背离第一凡尔体210的一侧中直接与第二凡尔体220接触的器件，保证第二凡尔体220在长时间频繁与第二耐磨环103接触的情况下，第二凡尔体220和第二耐磨环103均仍可以具有较长的使用寿命和密封效果。
相应地，第二耐磨环103的材质可以与第一耐磨环102的材质相同，且可以在第二端面上对应地形成第二容纳槽，使得第一耐磨环102和第二耐磨环103均可以通过过盈配合等方式分别嵌设于第一容纳槽和第二容纳槽之内，进而使第一耐磨环102和第二耐磨环103均与基体101形成稳定的相对固定关系。
如上所述，进液孔120连通分流器100的侧面和第一端面，在这种情况下，如图1、图17、图20和图22所示，进液孔120可以为直线状结构，且通过使进液孔120相对分流器100的轴向倾斜设置，即可保证进液孔120能够连通分流器100的侧面和第一端面，且使被输送的液体在进液孔120内的输送过程较为顺畅，降低液体在进液孔120内流动的阻碍，并且，在采用上述技术方案的情况下，可以降低进液孔120的加工难度。
在本申请的另一实施例中，如图18、图19、图21、图23、图24和图25所示，进液孔120可以包括轴向端和倾斜段，且轴向端和倾斜段相互连通。也即，进液孔120包括至少两段，两段的轴向非平行设置。并且，通过使轴向段沿分流器100的轴向延伸，且连通于第一端面，倾斜段相对分流器100的轴向倾斜延伸，且连通于侧面，使得进液孔120的出液方向与分流器100的轴向平行，进而使进液孔120的出液方向与第一凡尔体210的运动方向平行，提升第一凡尔体210的受力均匀性。具体地，可以通过自第一端面加工进液孔120的轴向段，且自分流器100的侧面倾斜地加工倾斜段，保证轴向段与倾斜段相互连通，即可形成本实施例请求保护的进液孔120。
在本申请上述实施例公开的多种结构的分流器组件中，技术方案之间可 以相互组合，例如，在分流器100包括基体101、第一耐磨环102和第二耐磨环103的情况下，亦可以使整个分流器100的第一端面为扩口状结构或平面状结构，或者，还可以使第一端面在自身径向的中部向靠近第二凡尔体220所在的方向凹陷设置。再比如，任一种结构的分流器组件中均可以设置有上述第三凡尔体和/或密封圈410，以提升分流器组件中各空间结构之间的密封效果。考虑文本简洁，此处不再一一组合后重复描述。
基于上述分流器组件，本申请实施例还公开一种阀箱500，该阀箱500与分流器组件配合使用，二者均可以被应用在柱塞泵内，作为柱塞泵中的两类主要部件，分流器组件可以安装在阀箱500内。
具体来说，阀箱500具有内腔510、进液通道520和排液通道530，内腔510用于安装分流器组件，进而使得内腔510中的部分被分流器组件分为高压腔501、低压腔502和交变腔503(如图13和图14)，在图11中，阀箱500被三条虚线分为四部分，四部分自右向左分别可以为高压腔501、低压腔502、交变腔503和柱塞腔，柱塞腔用以容纳柱塞710。显然，上述阀箱500的交变腔503不存在十字相贯线结构，且不同腔室之间过渡圆滑，从而可以降低阀箱500的应力，提升阀箱500的使用寿命。
并且，如图11和图12所示，进液通道520和分流器组件的进液孔120连通，排液通道530可与分流器组件的排液孔110连通。继而，如图15和图16所示，进液通道520内的液体可以自分流器组件的进液孔120被送入分流器100的第一端面所在的一侧空间内，之后，被送入分流器100的第一端面所在的一侧空间的液体可以自第一凡尔体210的连通孔211和分流器100的排液孔110被送入分流器100的第二端面所在的一侧空间，完成进液过程和排液过程。
基于上述实施例公开的分流器组件和上述阀箱500，如图12-图16所示，本申请实施例还公开一种柱塞泵，柱塞泵包括柱塞710、上述任一分流器组件和上述阀箱500，柱塞710和分流器组件均安装于阀箱500的内腔510，柱塞710与分流器组件沿转轴的轴向分布，且柱塞710与第一凡尔体210传动连接，动力端可以通过柱塞710与第一凡尔体210实现力的传递。当然，如图12所示，柱塞泵中还可以包括压盖720、压帽730、盘根总成740、盘根压帽751、盘根压环752、盘根隔环753、盘根耐磨套760和卡箍770等部件。
基于上述柱塞泵，如图12所示，可以在进液孔120位于侧面的孔口沿轴向的相背两侧均设置密封圈410，以利用密封圈410进一步为进液孔120位于侧面的孔口提供密封隔绝作用。
进一步地，如图12所示，可以使分流器100外周的各密封圈410的外侧均设置密封环420，密封环420密封于阀箱500和分流器100之间，也即， 在分流器100的外周设有密封圈410和密封环420，密封圈410被夹设在相邻的两个密封环420之间，密封圈410夹设进液孔120位于分流器100的侧面的孔口，从而利用密封环420进一步加强分流器100的侧面与阀箱500的内腔510的腔壁之间的密封连接可靠性。
同时，基于上述技术方案，如图12-图14所示，可以在阀箱500上设置泄流孔540，且泄流孔540的孔口连通于位于进液孔120同一侧的密封圈410和密封环420之间。在这种情况下，如果泄流孔540内出现液体溢流的情况，则可以确定该泄流孔540所在的位置对应的密封圈410发生损坏，便于工作人员及时更换对应位置的密封圈410，防止因损坏的密封圈410未能被及时更换而导致阀箱500和分流器组件内的其他器件损坏。
相应地，在进液孔120位于侧面的孔口的相背两侧均设有密封圈410和密封环420的情况下，如图12所示，可以使进液孔120相背两侧均设置泄流孔540，保证任一密封圈410损坏的情况下，均可以通过对应的泄流孔540获知该信息。
为了减少所需监控的泄流孔540的数量，如图13和图14所示，泄流孔540的数量可以为一个，且可以在分流器100上设置连接孔160，连接孔160的一端连通于位于进液孔120背离泄流孔540一侧的密封环420和密封圈410之间，连接孔160的另一端与泄流孔540连通。继而，进液孔120一侧的密封圈410和密封环420之间的空间可以通过泄流孔540直接与阀箱500之外连通，进液孔120另一侧的密封圈410和密封环420之间的空间则可以通过连接孔160间接地连通于泄流孔540，且与阀箱500之外连通，这亦可以保证进液孔120相背两侧的任一密封圈410损坏时，均可以通过泄流孔540是否溢流液体判断，且可以减少泄流孔540的设置数量，还可以提升阀箱500的整体结构强度，进而提升其稳定性。
本申请上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
