具体实施方式
作为一种实施方式，参照图1、图2，图1示意出块体10的结构，块体10包括进口1、第一出口2、第二出口3，第一安装腔4、第二安装腔5 和第一流体通道6，第一流体通道6与第一安装腔4、第二安装腔5连通。
参照图1-图6，块体10包括形成第一流体通道6的通道壁部61，所述进口1位于第一流体通道6的一端部，所述通道壁部61的周侧部62的至少一部分开设有第一阀口63，所述第一阀口63与第一安装腔4连通。通道壁部61设置的第一阀口63连通第一流体通道6和第一安装腔4。所述第一流体通道6的另一端为第二阀口64，第二阀口64连通第二安装腔5和第一流体通道6。
周侧部62为第一流体通道6对应的壁，第一阀口63开设于周侧部62，进口1位于第一流体通道6的端口，从进口1进入第一阀口63的流道为非直线流道。
所述块体10包括第一安装腔内壁41和第一环形部42，第一安装腔内壁41为形成第一安装腔4的一部分壁部，第一环形部42位于第一安装腔4中部位置。
第一环形部42包括第一贯穿孔421，第一贯穿孔421与第一安装腔4连通，且第一贯穿孔421与第一出口2连通。第一环形部42包括第一顶壁422、第一环形内壁423和第一环形外壁424，第一环形内壁423为形成第一贯穿孔421的一部分壁部，第一顶壁422、第一环形外壁424为形成第一安装腔4的一部分壁部，第一环形外壁424直径小于第一安装腔内壁41的内径，以第一安装腔4的轴向方向H(图6中所示)为高度方向，第一环形外壁424的高度小于第一安装腔内壁41。如此，第一环形外壁424与第一安装腔内壁41之间形成有块体10的流道。
所述块体10包括第一安装腔底壁43，以第一安装腔4的轴向方向H为高度方向，第一安装腔底壁43的高度低于第一顶壁422。第一安装腔底壁43自第一环形部42周向外缘位置径向延伸至第一安装腔内壁41。
第一安装腔底壁43至少包括第一子底壁431，第一子底壁431的一个末端位置相对靠近第一阀口63，定义第一子底壁43邻近第一阀口63的末端为第一末端4311，第一子底壁431的另一个末端位置相对远离第一阀口63，定义第一子底壁431远离第一阀口63的末端为第二末端4312，本文中，末端指第一子底壁431末端部。以第一安装腔4的轴向方向H为高度方向，第一子底壁431自其第一末端4311以高度递增的形式朝着第二末端 4312延伸。应当注意，本文中，在子底壁连接之处，第一末端4311、第二末端4312的界定可通过高度来界定，例如第一子底壁的第一末端是其高度最低位置，第一子底壁的第二末端是其高度最高位置。
应当了解，第一安装腔底壁43除了第一子底壁431外，还可以有其他结构，且第一末端并不局限为实际和第一阀口相邻，相对靠近和相对远离是针对第一末端和第二末端两者而言。
在流体从第一阀口63进入第一安装腔4中时，流体沿着第一子底壁431运动，其运动轨迹清晰，第一子底壁431以高度递增形式，使得流经该第一子底壁431的流体的流阻相对较小，有助于降低压降。
第一安装腔4包括第一中心线44，该第一中心线44垂直于第一流体通道6的方向，该第一中心线44将第一安装腔4分隔为第一安装腔子腔45和第二安装腔子腔46，其中第一安装腔子腔45相对靠近第一流体通道6的进口1，第二安装腔子腔46相对背离第一流体通道6的进口1，第一子底壁431的大部分为形成第二安装腔子腔46的一部分壁部。
更进一步，第一子底壁431的第一末端4311位于第二安装腔子腔46。如此有利于流体自第一流体通道6进入第一阀口63，并沿着第一子底壁431上升，对流体具有一定的引导作用，同时降低流体经第一阀口63进入第一安装腔4的压降。
第一安装腔底壁43至少包括第一平台部432，第一平台部432与第一子底壁431的第二末端4312连接，以第一安装腔4的轴向方向H为高度方向，第一平台部432的高度低于第一顶壁422，第一平台部432的高度高于第一子底壁431。定义第一平台部432与第一子底壁431的第二末端4312连接的端部为其第一末端4321，定义第一平台部432另外的末端为第二末端4322。在第一子底壁431的第二末端4312连接第一平台部432，有助于使进入第一安装腔4的流体逐渐地上升至第一平台部432的高度，使得流体平滑上升至一定高度，同时也有助于防止流体在第一安装腔4内打转。
第一安装腔底壁43至少包括第二子底壁433，第二子底壁433的高度低于第一子底壁431，第二子底壁433连接第一子底壁431和第一平台部432。本文中，定义朝着第一安装腔4开口方向为向上方向，定义朝着第一 安装腔底壁43方向为向下方向，所述块体10包括自第一子底壁431的第一末端4311向下延伸的第一侧壁4313和自第一平台部432的第二末端4322向下延伸的第二侧壁4323。第一安装腔4包括第一槽孔47，第一侧壁4313、第二侧壁4323以及第二子底壁433为形成第一槽孔47的一部分壁部，第一阀口63设置于第一安装腔内壁41形成该第一槽孔47的一部分壁部，由于第一流体通道6与第一安装腔4在第一阀口63处连通，故第一阀口63也设置于第一安装腔内壁41。由于在第一阀口63周围设置了第一槽孔47，流体经第一阀口63进入第一安装腔4的通道相对较宽，使得流体经第一阀口63后的流阻相对较小。第一阀口63的一部分位于第一安装腔子腔45，第一阀口63的另一部分位于第二安装腔子腔46，第一槽孔47的大部分位于第一安装腔子腔45，如此使得第一阀口63进入的流体从第一槽孔47承接过渡到第一子底壁431，使得流体运动平滑，有助于降低压降。
所述块体10还包括第二安装腔内壁51和第二环形部52，第二安装腔内壁51为形成第二安装腔5的一部分壁部，第二环形部52位于第二安装腔5中部位置。
第二环形部52包括第二贯穿孔521，第二贯穿孔521与第二安装腔5连通，且第二贯穿孔521与第二出口3连通。第二环形部52包括第二顶壁522、第二环形内壁523和第二环形外壁524，第二环形内壁523为形成第二贯穿孔521的一部分壁部，第二顶壁522、第二环形外壁524为形成第二安装腔5的一部分壁部，第二环形外壁524内径小于第二安装腔内壁51，以第二安装腔5的轴向方向为高度方向，第二环形外壁524的高度小于第二安装腔内壁51。
所述块体10包括第二安装腔底壁53，以第二安装腔5的轴向方向为高度方向，第二安装腔底壁53的高度低于第二顶壁522。第二安装腔底壁53自第二环形部52周向外缘位置径向延伸至第二安装腔内壁51。
所述第二安装腔底壁53至少包括第三子底壁531，第三子底壁531的一个末端位置相对靠近第二阀口64，定义第三子底壁531邻近第二阀口64的末端为第一末端5311，第三子底壁531的另一个末端位置相对远离第二 阀口64，定义第三子底壁531远离第二阀口64的末端为第二末端5312，本文中，末端指第三子底壁531末端部。以第二安装腔5的轴向方向为高度方向，第三子底壁531自其第一末端5311以高度递增的形式朝着其第二末端5312延伸。
第二安装腔5包括第二中心线54，该第二中心线54平行于第一流体通道6的方向，该第二中心线54将第二安装腔5分隔为第三安装腔子腔55和第四安装腔子腔56，第三安装腔子腔55与第四安装子腔56位于第一流体通道6的延伸方向的两侧。第三子底壁531的大部分位于第三安装腔子腔55。
第二安装腔底壁53至少包括第四子底壁533，第四子底壁533的一个末端位置相对靠近第二阀口64，定义第四子底壁533邻近第二阀口64的末端为第一末端5331，第四子底壁533的另一个末端位置相对远离第二阀口64，定义第四子底壁533远离第二阀口64的末端为第二末端5332，本文中，末端指第四子底壁533末端部。以第二安装腔5的轴向方向为高度方向，第四子底壁533自其第一末端5331以高度递增的形式朝着其第二末端5332延伸。第四子底壁533的大部分位于第四安装腔子腔56。通过第三子底壁531、第四子底壁533的设置，流体经第二阀口64进入第二安装腔5后，流体沿着第三子底壁531和第四子底壁533运动，在第二安装腔5内流体运动规则，不容易因运动混乱(例如打转)而造成压降的增加。
作为一种实施方式，第二安装腔底壁53包括第二平台部532，第二平台部532与第三子底壁531的第二末端5312连接，以第二安装腔5的轴向为高度方向，第二平台部532的高度高于第三子底壁531，第二平台部532的高度低于第二顶壁522。如此，流体经第二阀口64进入第二安装腔5，然后流体沿着第三子底壁531运动到第二平台部532，由于第二平台部532的高度高于第三子底壁531，且经过第三子底壁531的过渡，流体再进入第二贯穿孔521，其压降较低。
第四子底壁533的第二末端5332与第二平台部532连接，如此，经第二阀口64进入第二安装腔5的流体，大部分可以分成两股，一股沿着第三子底壁531，另一股沿着第四子底壁533，然后大部分的流体经第二平台部532进入第二贯穿孔521，如此，使得流体在第二安装腔5内流动阻力 较小，压降相对较低。
作为另一种实施方式，第三子底壁531的第二末端5312与第四子底壁533的第二末端5332连接，此时定义第三子底壁531的第二末端5312为第三子底壁531高度最高位置，定义第四子底壁533的第二末端5332为第四子底壁533高度最高位置。如此，经第二阀口64进入第二安装腔5的流体，大部分可以分成两股，一股沿着第三子底壁531，另一股沿着第四子底壁533，然后大部分的流体经第三子底壁531、第四子底壁533的邻近末端位置进入第二贯穿孔521，如此，使得流体在第二安装腔5内流动阻力较小，压降相对较低。
块体10至少包括第一侧部、第二侧部和第三侧部，流体进口1位于第一侧部，第一出口2位于第二侧部，第二出口3位于第三侧部，第一侧部与第三侧部相对设置，第二侧部连接第一侧部和第三侧部。
作为另一种实施方式，参照图7，图7示意出块体20的大体结构，块体20包括进口1、第一出口2、第二出口3，第一安装腔4、第二安装腔5和第一流体通道6，第一流体通道6与第一安装腔4、第二安装腔5连通。
块体20包括形成第一流体通道6的通道壁部61，进口1位于第一流体通道6的一个端部，所述通道壁部61周侧部62开设有第一阀口63，通道壁部61周侧部62还开设有第二阀口64，第一阀口63连通第一流体通道6和第一安装腔4，第二阀口64连通第二安装腔5和第一流体通道6。本文中，通道壁部61的周侧部62是指通道壁部61的周侧位置。第一安装腔4结构参照上述实施方式。
在本实施方式中，第二安装腔底壁53至少包括第三子底壁531，第三子底壁531的一个末端位置相对靠近第二阀口64，定义第三子底壁531邻近第二阀口64的末端为第一末端5311，第三子底壁531的另一个末端位置相对远离第二阀口64，定义第三子底壁531远离第二阀口64的末端为第二末端5312。第三子底壁531自其第一末端5311以高度递增的形式朝着第二末端5312延伸。
第二安装腔5包括第三中心线57，该第三中心线57垂直于第一流体 通道6的方向，该第三中心线57将第二安装腔5分隔为第五安装腔子腔58和第四安装腔子腔59，其中第五安装腔子腔58相对靠近第一流体通道6的进口1，第六安装腔子腔59相对背离第一流体通道6的进口1，第三子底壁531的大部分为形成第六安装腔子腔59的一部分壁部。
第二安装腔底壁53至少包括第二平台部532，第二平台部532与第三子底壁531的第二末端5312连接，以第二安装腔5的轴向方向为高度方向，第二平台部532的高度低于第二顶壁522，第二平台部532的高度高于第三子底壁531。第二平台部532包括第一末端5321和第二末端5322，第一末端、第二末端的定义如上所述。
第二安装腔底壁53至少包括第五子底壁534，第五子底壁534的高度低于第三子底壁531，第五子底壁534连接第三子底壁531和第二平台部532。本实施方式中，定义朝着第二安装腔5开口方向为向上方向，定义朝着第二安装腔底壁53方向为向下方向，所述块体20包括自第三子底壁531的第一末端5311向下延伸的第一侧壁5313和自第二平台部532的第二末端5322向下延伸的第二侧壁5323。
更进一步，第三子底壁531的第一末端5311位于第六安装腔子腔59。如此有利于流体自第一流体通道6进入第二阀口64，并沿着第三子底壁531上升至第二平台部532，对流体具有一定的引导作用，同时降低流体经第一阀口63进入第一安装腔4的压降。
第二安装腔5包括第二槽孔50，第一侧壁5313、第二侧壁5323以及第五子底壁534为形成第二槽孔50的一部分壁部，第二安装腔内壁51形成该第二槽孔50的一部分壁部设置第二阀口64，其解释参照上文对第一阀口63所述。由于在第二阀口64周围设置了第二槽孔50，流体经第二阀口64进入第二安装腔5的通道相对较宽，使得流体经第二阀口64后的流阻相对较小。第二阀口64的一部分位于第五安装腔子腔58，第二阀口64的另一部分位于第六安装腔子腔59，第二槽孔50的大部分位于第五安装腔子腔58，如此使得第二阀口64进入的流体从第二槽孔50承接过渡到第三子底壁531，使得流体运动平滑。
