具体实施方式
如图1至图14所示，本实施方式的球阀包括驱动机构10、阀体组件11、传动机构12和阀芯部件13。如图2所示，驱动机构10包括定子线圈1、电机轴部件2、转子部件3和套管8，电机轴部件2与转子部件3固定连接，转子部件3转动带动电机轴部件2转动，套管8为一端封闭的管状体，定子线圈1套设于套管8外，至少部分转子部件3内置于套管8。
如图3所示，转子部件3在轴向中心线或者轴向中心线附近设置有第一贯穿孔55，电机轴部件2穿过第一贯穿孔55，电机轴部件2与转子部件3通过注塑固定连接，电机轴部件2与转子部件3还可以设置为键槽配合，从而增强电机轴部件2与转子部件3结合的牢固性。
定义套管8封闭的一端为顶部，如图4所示，套管8的顶部的中心处或者中心处附近设置有向外凸出的第一盲孔部82，电机轴部件2靠近转子部件3的一端伸入第一盲孔部82，电机轴部件2与第一盲孔部82间隙配合，第一盲孔部82对电机轴部件2起到限位的作用。
如图1和图2所示，阀体组件11包括第一阀体部件4和第二阀体部件6，当阀 体组件11由塑料材料制备时，套管8与第二阀体部件6可以通过注塑工艺一体成型，如图4所示，如此设置，套管8与第二阀体部件6之间的密封性更好。在一实施例中，套管8和第二阀体部件6之间也可以通过设置连接座的方式固定连接。
如图5所示，第一阀体部件4包括阀体部40，阀体部40的一端开口设置，阀体部40包括端口部45，端口部45位于阀体部40的开口端，定义阀体部40开口的一端为顶部，与顶部相对的另一端为底部，第二阀体部件6的一端与端口部45相配合，并通过螺栓连接与阀体部40相固定，在一实施例中，第二阀体部件6与阀体部40也可以通过焊接等其它形式固定连接。
阀体部40的端口部45的端面部还设置有环形凹槽450，环形凹槽450内设置有密封垫，从而提高第二阀体部件6与阀体部40的连接处的密封性。在一实施例中，当第二阀体部件6与阀体部40通过焊接固定时，则可以不需要设置密封垫。
如图2所示，阀体组件11形成有容纳腔，容纳腔包括第一阀体部件腔50，第一阀体部件腔50位于阀体部40内，阀芯部件13至少部分容置于第一阀体部件腔50内，容纳腔还包括第二阀体部件腔65，第二阀体部件腔65位于第二阀体部件6内，传动机构12至少部分位于第二阀体部件腔65内。
如图2和图6所示，传动机构12包括太阳轮20、行星轮21、第一齿圈22、第二齿圈23、第一安装板24、第二安装板25和齿轮轴26，在本实施方式中行星轮21的数量为三个，相应的齿轮轴26的数量也为三个，第一安装板24和第二安装板25可以为圆环形结构，第一安装板24的中心圆通孔和第二安装板25的中心圆通孔便于电机轴部件2与太阳轮20的配合，三个行星轮21通过齿轮轴26以能够转动的方式设置在第一安装板24和第二安装板25之间，三个行星轮21都与太阳轮20啮合连接。
第一齿圈22和第二齿圈23都具有内齿部，行星轮21的第一端在第一齿圈22的内齿部与第一齿圈22啮合连接，行星轮21的第二端在第二齿圈23的内齿部与第二齿圈23啮合连接。第二齿圈23在背向行星轮21的一侧与第二阀体部件6固定连接，例如通过过盈配合或者限位配合的方式安装于第二阀体部件6。
在一实施例中，当第二阀体部件6和第二齿圈23都由塑料材料制备时，第二齿圈23可以与第二阀体部件6一体成型，例如通过注塑工艺一体成型，如此设置，减少了球阀的零部件数量，且装配更方便。
电机轴部件2与传动机构12传动连接，太阳轮20在轴向中心线或者轴向中心线附近设置有第二贯穿孔56(参考图6)，电机轴部件2穿过第二贯穿孔56，电机 轴部件2与太阳轮20可以过盈压接或者卡合连接，当电机轴部件2转动时，太阳轮20同步转动，进而带动行星轮21、第一齿圈22和第二齿圈23转动。在传动比相同时，这种传动机构结构相对紧凑，体积较小，从而使球阀的体积相对减小。
如图7所示，第一齿圈22具有中心孔220，如图8所示，阀芯部件13包括阀芯球130和阀芯柱30，阀芯柱30的第一端伸入中心孔220并过盈压接，或者中心孔220可以异形设置，相应地阀芯柱30的形状与中心孔的形状相配合而实现转动带动，即阀芯柱30与第一齿圈22配合来实现第一齿圈22带动阀芯柱30转动。阀芯柱30的第二端与阀芯球130传动连接或者阀芯柱30与阀芯球130为一体结构，当阀芯柱30转动时，能够带动阀芯球130一起转动。
在一实施例中，阀芯球130也可以设置有卡槽，阀芯柱30与卡槽相配合实现转动带动。在本实施方式中，阀芯柱30与阀芯球130为一体结构。
在一实施例中，阀芯球130也可以设置为圆柱形和椭圆形等常见形状。
如图8和图2所示，阀芯球130包括平台部131，平台部131位于阀芯部件13的转动中心或者靠近阀芯部件13的转动中心，阀芯柱30与平台部131固定连接或者阀芯柱30与平台部131为一体结构，或者，阀芯柱30包括平台部131，平台部131与阀芯球130固定连接或者平台部131与阀芯球130为一体结构。第一齿圈22朝向阀芯部件13的一侧与平台部131相抵接，平台部131的外径L1小于第一齿圈22的内径L2，从而减小驱动阀芯部件13所需的驱动力。
如图2和图8所示，阀芯球130朝向第一齿圈22的一侧还设置有平面部132，平面部132围绕平台部131设置，且平台部131在朝向第一齿圈22的方向上凸出于平面部132，如图2所示，第一齿圈22朝向阀芯部件13的一侧与平面部132之间保持预设距离。在一实施例中，平面部132也可以设置为曲面部或锥面部等。
在本实施方式中，传动机构12与阀芯部件13直接接触，即第一齿圈22朝向阀芯部件13的一侧与平台部131相抵接，如此设置，省去了第一阀体部件4的阀盖，减少了球阀的零部件，可以使得球阀的结构较为紧凑。
在一实施例中，第一齿圈22的中心孔220可以设置为阶梯孔部，阶梯孔部包括阶梯部，阀芯柱30包括平台部，平台部位于阀芯柱30朝向第一齿圈22的一端，阀芯柱30伸入阶梯孔部，阀芯柱30的平台部与阶梯部相抵接，阀芯球130朝向第一齿圈22的一侧还设置有平面部，第一齿圈22朝向阀芯部件13的一侧与所述阀芯球130的平面部之间保持预设的距离，如此设置，使得第一齿圈22与阀芯部件13的接触面的直径更小，更有利于减小驱动阀芯部件13所需的驱动力。在一实 施例中，具有阶梯孔部的第一齿圈22可以同时与上述两种形式的平台部抵接。
如图8所示，阀芯部件13在轴向中心线或者轴向中心线附近设置有通孔57，通孔57的一部分位于阀芯柱30，一部分位于阀芯球130。电机轴部件2穿过通孔57，电机轴部件2与通孔57所对应的内壁间隙配合，在一实施例中，电机轴部件2转动时不能直接带动阀芯部件13转动，可以通过第一齿圈22带动阀芯部件13转动。
如图2和图10所示，阀体部40还包括内底部47，内底部47在与通孔57对应的位置设置有第二盲孔部49，第二盲孔部49的轴线与第一盲孔部82的轴线重合或者近似重合，电机轴部件2靠近阀芯部件13的一端伸入第二盲孔部49，电机轴部件2与第二盲孔部49间隙配合，第二盲孔部49对电机轴部件2起到限位的作用。
在本实施方式中，电机轴部件2依次穿过转子部件3、太阳轮20和阀芯部件13，电机轴部件2的第一端限位于第一盲孔部82内，电机轴部件2的第二端限位于第二盲孔部49内，且电机轴部件2与阀芯部件13间隙配合，如此设置，能够防止阀芯部件13在转动过程中发生偏斜和晃动，有利于提高阀芯部件13的稳定性。
如图9所示，阀芯部件13在朝向内底部47的一侧还设置有至少一个限位柱31，在本实施方式中，设置有两个限位柱31，限位柱31对称设置在阀芯部件13的轴线两侧，两个限位柱31可以与阀芯部件13为一体结构。
如图10所示，阀体部40的内底部47设置有与限位柱31相配合的限位凹槽，限位柱31与限位凹槽之间滑动配合，限位凹槽包括至少一个弧形凹槽32，在本实施方式中，限位凹槽包括两个弧形凹槽32，两个弧形凹槽32以第二盲孔部49为中心对称分布。
限位柱31至少部分伸入弧形凹槽32，弧形凹槽32的内壁与限位柱31之间滑动配合，通过与弧形凹槽32的内壁配合进行限位，弧形凹槽32的两端部可以限制阀芯部件13的转动范围，在阀芯部件13顺时针转动时，当弧形凹槽32的其中一端部的内壁与限位柱31相抵接时，阀芯部件13在顺时针方向上停止转动，一般情况下通过设置弧形凹槽32两端部之间的圆弧角大小可以限制阀芯部件13的转动范围，在本实施方式中，弧形凹槽32的圆弧角设为90°，在不同工作环境，弧形角可以适应性设置。
本实施例提供的球阀的工作原理是：当电机轴部件2顺时针转动时，带动太阳轮20顺时针转动，通过啮合连接带动行星轮21转动，第二齿圈23固定不动，行星轮21绕自身轴线转动的同时，还以太阳轮1为中心作周向转动，即以电机轴 部件2为中心转动，并与第二齿圈23啮合转动，进而带动第一齿圈22转动，第一齿圈22带动阀芯柱30一起转动，同时阀芯柱30带动阀芯球130转动，转动角度为0°-90°，当弧形凹槽32的一端部的内壁与限位柱31相抵接时，阀芯部件13在转动的方向上停止转动，电机轴部件2逆时针转动时同理。
如图5所示，阀体部40还开设有第一开口部401、第二开口部402、第三开口部403和第四开口部404，第一开口部401、第二开口部402、第三开口部403和第四开口部404按顺时针方向或逆时针方向的顺序设置在阀体部40的周侧，并且相对于阀体部40的中心呈对称设置。
第一阀体部件4还包括第一接口部41、第二接口部42、第三接口部43和第四接口部44，如图11所示，第一接口部41设置有第一通道71，第二接口部42设置有第二通道72，第三接口部43设置有第三通道73，第四接口部44设置有第四通道74，第一接口部41的一端与第一开口部401固定连接且连接处密封，第二接口部42的一端与第二开口部402固定连接且连接处密封，第三接口部43的一端与第三开口部403固定连接且连接处密封，第四接口部44的一端与第四开口部404固定连接且连接处密封。
如图11所示，阀芯球130内部设置有第一阀芯通道14和第二阀芯通道15，本实施例的球阀至少包括两种工作状态：第一工作状态和第二工作状态，当球阀处于第一工作状态时，如图11所示，第一通道71通过第一阀芯通道14与第二通道72连通，第三通道73通过第二阀芯通道15与第四通道74连通；当球阀处于第二工作状态时，如图12所示，第一通道71通过第一阀芯通道14与第四通道74连通，第二通道72通过第二阀芯通道15与第三通道73连通。
如图5所示，阀体部40的内周壁在第一开口部401靠近内底部47的一侧附近设置有第一凸出部411，第一凸出部411相对于阀体部40的内周壁向内凸出，第一凸出部411远离第一开口部401的一端延伸至内底部47，第一凸出部411靠近第一开口部401的一端形成有第一圆弧部412，第一圆弧部412位于第一开口部401的下方。第一圆弧部412所对应的中心轴线与第一开口部401的中心轴线重合或者近似重合，第一圆弧部412所对应的圆心角的大小这里不作具体限定，在本实施方式中，第一圆弧部412所对应的圆心角为180°，从而有利于阀体部40注塑成型时的脱模工艺。
如图13所示，第二阀体部件6在朝向阀体部40的一侧设置有第二凸出部511，第二凸出部511与第一凸出部411相对设置，第二凸出部511位于第一凸出部411 的上部，第二凸出部511靠近第一开口部401的一端形成有第二圆弧部512，第二圆弧部512与第一圆弧部412相对设置，第二圆弧部512所对应的中心轴线与第一开口部401的中心轴线重合或者近似重合，第二圆弧部512所对应的圆心角的大小这里不作具体限定，在本实施方式中，第二圆弧部512所对应的圆心角为180°。如图14所示，第一圆弧部412和第二圆弧部512配合形成圆柱形的空间60。
如图2所示，球阀在上述空间60内还设置有密封圈90，密封圈90限位于第一圆弧部412和第二圆弧部512之间，密封圈90的内径大于第一通道71的直径，也大于阀芯部件13的内部通道的直径，密封圈90的第一端与阀体部40所对应的内壁相抵接，密封圈90的第二端与阀芯部件13所对应的外壁部相抵接，并且密封圈90还分别与第一圆弧部412和第二圆弧部512相压紧抵接。
相关技术中，为了安装密封圈，第一开口部401与第一阀体部件4采用分离的方式，密封圈90通过第一开口部401与第一阀体部件4的连接处装入，需要先将密封圈90装入第一阀体部件4内，然后再将第一开口部401与第一阀体部件4通过焊接或螺接等方式固定，阀芯部件13装入第一阀体部件4的方向与密封圈90装入第一阀体部件4的方向是不一致的。而在本实施例中，通过第一圆弧部412和第二圆弧部512的配合，能够实现对密封圈90的限位，通过在阀体部40设置第一凸出部411和在第二阀体部件6设置第二凸出部511的方式，使得密封圈90的装配比较容易，阀芯部件13和密封圈90都是从端口部45装入第一阀体部件4，零部件安装较为简单。
球阀在第二开口部402、第三开口部403和第四开口部404以相同或者相似的方式形成有圆柱形的空间，并设置有密封圈90。
如图5所示，阀体部40的内周壁在第一开口部401和第二开口部402之间还设置有第三凸出部46，第三凸出部46从阀体部40的内底部47延伸至阀体部40的顶部，在本实施方式中，第三凸出部46的第一侧与第一开口部401对应的第一凸出部411平滑连接或者近似平滑连接，第三凸出部46的第二侧与第二开口部402对应的第一凸出部411平滑连接或者近似平滑连接，第三凸出部46的第一侧和第二侧相对。第三凸出部46的至少一部分位于两个第二凸出部511之间，第二凸出部511限位于两个第三凸出部46之间，能够提高第二凸出部511与第一凸出部411的配合精度。
如图5和图13所示，第三凸出部46在靠近阀体部40的顶部的一端的两侧分别设置有第一凸凹部461，第二凸出部511在与第一凸凹部461相对应的部位设置有 第二凸凹部513，第一凸凹部461与第二凸凹部513相配合，可以使得第二阀体部件6与阀体部40结合更牢固。
第三凸出部46位于两第二凸出部511之间部分的厚度小于第一凸出部411的厚度，第三凸出部46的厚度小的部分与厚度大的部分的连接处形成有肩部460。第二阀体部件6在两个第二凸出部511之间还设置有第四凸出部48(参考图13)，第四凸出部48的两侧与第二凸出部511平滑连接或者近似平滑连接。第四凸出部48与肩部460相对设置，第四凸出部48朝向阀体部40的一端与肩部460相抵接，能够对第二阀体部件6起到限位的作用。
