具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例，为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施例，对本申请进行进一步详细描述。本文中，诸如“第一”和“第二”等之类的关系术语仅仅用来将一个与另一个具有相同名称的部件区分开来，而不一定要求或者暗示这些部件之间存在任何这种实际的关系或者顺序。
如图1至图3所示，本申请实施例提供一种控制阀1，包括阀体10、阀芯20和密封部件41，阀体10包括侧壁部11，控制阀1具有阀腔101，侧壁部11为阀腔101的周壁或至少是周壁的一部分，阀芯20的至少部分位于阀腔101且能够在带动下转动，控制阀1还可以包括驱动装置50和密封圈43，驱动装置50包括驱动件，驱动件可以为电机或者电机和减速齿轮组，阀芯20能够在驱动装置50内的驱动件的带动下转动，沿阀芯20的径向，密封部件41的至少部分位于阀芯20和侧壁部11之间，图1中，阀体10还包括底壁部12和顶壁部13，底壁部12、顶壁部13和侧壁部11围合形成阀腔101，密封圈43位于顶壁部13和阀芯20之间，侧壁部11的至少部分位于底壁部12和顶壁部13之间，底壁部12和顶壁部13的其中一者与侧壁部11一体成型，另一者与侧壁部11密封设置，例如在图1中，顶壁部13与侧壁部11一体成型，底壁部12可以通过焊接工艺与侧壁部11之间固定连接且密封设置，防止流体外泄，密封圈43位于顶壁部13 和阀芯20之间，此时阀芯20在装配过程中，从阀体10的底部向顶部方向装配，能够减小密封圈43的变形，提高密封圈43的密封性能。控制阀1可以包括至少五个通道30，侧壁部11具有至少五个连通口，连通口与阀腔101连通，每个通道30的一端贯穿侧壁部11形成连通口，每个通道30的另一端形成控制阀1的阀端口102，流体能够从阀端口102进入或者离开控制阀1，在具体实施时，控制阀1包括的通道30的数量以及连通口的数量可以根据用户的需求进行设定。
为便于实现控制阀1与流体控制系统中的其他部件装配，提高控制阀1与其他部件的集成化程度，在一些实施例中，如图1至图3，阀体10还包括安装部14，安装部14与侧壁部11固定连接且位于侧壁部11背离阀腔101的一侧，例如安装部14和侧壁部11可以一体成型，安装部14具有安装面141，控制阀1的阀端口102贯穿安装面141，使得控制阀1的阀端口102都布置于安装面141上且各阀端口102的朝向相同，可以相对简化控制阀1与其他部件的装配步骤以及减少连接部分的泄漏点，增加密封的可靠性。
在一些实施例中，密封部件41沿垂直于密封部件41高度方向的横截面为弧形结构，密封部件41包括密封主体部410，沿阀芯20的径向，密封主体部410位于阀芯20和侧壁部11之间，密封主体部410的内表面与阀芯20接触，密封主体部410的外表面与侧壁部11接触，定义侧壁部11在与密封主体部410接触的区域内具有的连通口为第一连通口311，此时的侧壁部11上的连通口包括第一连通口311，第一连通口311沿侧壁部11的高度方向和垂直于侧壁部11的高度方向阵列排布，此时，与第一连通口311连通的阀端口102沿侧壁部11的高度方向和垂直于侧壁部11的高度方向阵列排布，如图2，安装部14的安装面141的轮廓大致为矩形结构，安装面141的长度方向与侧壁部11的高度方向平行，此时与第一连通口311连通的阀端口102沿安装面141的长度方向和宽度方向阵列排布。
如图2至图4所示，侧壁部11上的连通口包括第一连通口311，第一连通口311沿侧壁部11的高度方向和侧壁部11的周向排布，沿侧壁部11的周向，侧壁部11排布有两个第一连通口311，如图2和图4所示，在本 实施例中侧壁部11具有八个第一连通口311，沿侧壁部11的高度方向，侧壁部11具有4排第一连通口311，每排具有两个第一连通口311，相应地，控制阀1具有八个与第一连通口311一一对应且连通的第一阀端口312；如图3、5至图7所示，密封部件41的横截面为弧形结构，当密封部件41包括密封主体部410时，密封主体部410位于阀芯20和侧壁部11之间，密封主体部410具有贯穿密封部件41的通孔411，通孔411与第一连通口311的数量相同且对应连通，通孔411沿密封部件41的高度方向和密封主体部410的周向排布，沿密封主体部410的周向，密封主体部410排布有两个通孔411，本实施例中，密封主体部410具有八个通孔411，沿密封主体部410的高度方向，密封主体部410具有4排通孔411，每排具有两个通孔411，密封主体部410的内表面为弧面，该弧面与阀芯20接触，定义密封主体部410的弧面对应的圆心角为α，则α大于或等于100度且小于或等于180度，可选地，α大于100度小于等于110度，通过上述设置，能够降低密封部件制造模具的制造难度，从而降低密封部件41的制造难度，降低密封部件41的制造成本。
如图7所示，在一些实施例中，在垂直于侧壁部11高度方向的横截面上，定义过沿周向排布的两个第一连通口311的边缘和侧壁部11的圆心所成的最大圆心角为β，β＝90°，相应地，在垂直于密封部件41的高度方向的横截面上，过密封部件41的两个通孔411的边缘和密封部件41的弧面的圆心所成的最大圆心角为90度，在控制阀1运行过程中，由于驱动件的控制精度或者信号传递的延时或者阀芯20的转动惯量影响，阀芯20具有转动公差，定义转动公差的角度为θ，则α≥β+2θ。可选地，阀芯20的转动公差角度可以为±5度，即当驱动件停止驱动阀芯20转动时，由于驱动件的控制精度或者信号传递的延时或者阀芯20的转动惯量影响，阀芯20可能会转动至距离设定角度之前5度时停止或者超过设定角度后继续旋转5度，从而使阀芯20产生转动公差，为了使密封部件41能够在阀芯20转动的各个行程范围内均与阀芯20接触，使密封部件41具有较好的密封性能，且同时使密封部件41具有较大的膨胀空间和较低的制造难度，在一些实施例中，密封主体部410的弧面对应的圆心角α为100度。
为了使密封部件41稳定地限位于阀体10的阀腔101内，如图7至图11所示，在一些实施例中，密封部件41还包括位于密封主体部410周向两端的限位部414，限位部414具有限位面4141，限位面4141连接于密封部件41的内表面和外表面之间，阀体10还包括止挡部15，如图9和图10所示，止挡部15为侧壁部11的一部分，或者如图11所示，止挡部15可以与侧壁部11固定连接且止挡部15位于阀腔101内，止挡部15具有止挡面151，该止挡面151可以沿侧壁部11的径向方向延伸或者与径向方向之间呈角度延伸，止挡面151位于阀腔101内，限位面4141和止挡面151接触设置。通过上述设置，使得限位面4141和止挡面151相互配合，防止密封部件41的转动，提高密封部件41的密封性能。
由于密封部件41的横截面为弧形结构，在阀芯20挤压密封部件41过程中易造成阀芯20的偏心，参阅图9，在一些实施例中，控制阀1还包括平衡密封块42，沿阀芯20的径向，平衡密封块42位于侧壁部11和阀芯20之间，平衡密封块42和密封部件41分设于阀芯20径向方向的两侧，平衡密封块42朝向阀芯20的表面为弧面，平衡密封块42的弧面的轴心与密封主体部410的内表面的轴心重合且两者的半径相等；可选地，平衡密封块42的高度可以与密封部件41的高度相等，沿阀芯20的高度方向，密封部件41与阀芯10接触的高度和平衡密封块42与阀芯20接触的高度相等，通过上述设置能够使平衡密封块42与密封部件41对阀芯20产生大小相同方向相反的作用力，能够保持阀芯20与侧壁部11同轴，提高阀芯20转动的稳定性，防止阀芯20偏心引起流体外泄，提高控制阀1的密封性能以及提高控制阀1对流体控制的稳定性。
为使阀芯20在较小的驱动力下稳定地转动，如图5至图7所示，在一些实施例中，密封部件41包括固定连接的第一弹性垫412和第一密封件413，第一弹性垫412位于第一密封件413和侧壁部11之间，第一密封件413位于第一弹性垫412和阀芯20之间且与阀芯20接触，第一密封件413的主要材料可以为特氟龙，例如第一密封件413可以采用特氟龙加工形成，第一弹性垫412可以采用橡胶加工而成，第一弹性垫412与第一密封件413通过粘合固定形成一体结构，此时第一密封件412朝向阀芯20的表面的粗 糙度小于第一弹性垫412背离阀芯20的表面，通过设置第一密封件412的主要材料为特氟龙，使得第一密封件412不仅可以起到密封的作用，还具有一定的润滑性能，可以降低阀芯20与密封部件41之间的摩擦力，从而可以相对降低控制阀1的驱动力。第一弹性垫421包括主体部和凸出部，凸出部与侧壁部11接触，该凸出部可以包括多个相交的轴向凸起部和周向凸起部，轴向凸起部沿第一弹性垫421高度方向延伸，周向凸起部沿沿第一弹性垫421周向方向延伸，通过设置多个凸出部能够提高密封部件的压缩变形量，提高密封部件41的密封性能。
基于此，图9和图12，平衡密封块42可以包括固定连接的第二弹性垫423和第二密封件424，第二弹性垫423位于第二密封件424和侧壁部11之间，第二密封件424位于第二弹性垫423和阀芯20之间且与阀芯20接触，第二密封件424的主要材料可以为特氟龙，例如第二密封件424可以采用特氟龙加工形成，第二弹性垫423可以采用橡胶加工而成，第二弹性垫423与第二密封件424通过粘合固定形成一体结构，此时第二密封件424朝向阀芯20的表面的粗糙度小于第二弹性垫423背离阀芯20的表面，通过设置第二密封件424的主要材料为特氟龙，使得第二密封件424不仅可以起到密封的作用，还具有一定的润滑性能，可以降低阀芯20与密封部件41之间的摩擦力，从而可以相对降低控制阀1的驱动力。
为使平衡密封块42稳定限位于阀腔101内，如图9至图12所示，在一些实施例中，沿侧壁部11的径向，阀体10具有容纳腔152以及开口153，容纳腔152通过开口153与阀腔101连通，容纳腔152的横截面面积大于开口153的横截面面积，平衡密封块42包括相互固定连接的第一部分421和第二部分422，第一部分421的横截面面积大于第二部分422的横截面面积，第一部分421位于容纳腔152，第二部分422位于阀芯20和第一部分421之间，此时的第二部分422穿过开口153与阀芯20接触，其中，横截面为沿垂直于平衡密封块42的高度方向或者沿垂直于侧壁部11的高度方向切割控制阀1得到的截面。通过上述设置，能够使平衡密封块42限位于容纳腔152内，便于平衡密封块42的安装。当平衡密封块42包括第二弹性垫423和第二密封件424时，第一部分421可以为第二弹性垫423， 第二部分422可以为第二密封件424，或者第一部分421可以为第二弹性垫423和第二密封件424的一部分形成的结构，第二部分422可以为第二密封件424的另一部分形成的结构。
进一步参阅图1至图3、图9以及图13至图15，在一些实施例中，侧壁部11的连通口还包括第二连通口321，第二连通口321位于侧壁部11高度方向的一端且远离密封部件41设置，阀芯20为柱状结构，阀芯20包括顶板201、底板202、内部导通腔21、多个外部导通腔22、第一隔板23和第二隔板24，沿阀芯20的高度方向，多个外部导通腔22、第一隔板23和第二隔板24位于顶板201和底板202之间，内部导通腔21位于顶板201和底板202之间且贯穿底板202。至少部分外部导通腔22分布于内部导通腔21的外周侧，第一隔板23位于内部导通腔21和外部导通腔22之间，第二隔板24位于相邻两个外部导通腔22之间；第一隔板23具有孔道231，内部导通腔21通过孔道231与一部分数量的外部导通腔22连通，此时的第二连通口321通过阀腔101与内部导通腔21连通，第一连通口311通过密封主体部410的通孔411与外部导通腔22连通，每个外部导通腔22通过第二隔板24分隔为独立空间；旋转阀芯20能够通过一个外部导通腔22将与该外部导通腔22对应的两个阀口导通或截止，和/或，旋转阀芯20能够通过内部导通腔21、孔道231以及外部导通腔22将对应的两个阀口导通或截止，该两个阀口的其中一个与内部导通腔21对应，另一个与外部导通腔22对应。通过上述设置，能够使一个控制阀1可对多个流路进行控制，在使用时会更加方便紧凑。
如图13所示，为了对密封部件41进行限位，在一些实施例中，阀体10的顶壁部13与侧壁部11注塑为一体结构，此时阀体10还包括凸出部16，凸出部16凸出于顶壁部13且位于阀腔内，凸出部16具有第一限位槽16a，第一限位槽16a的槽口与阀腔连通，侧壁部11的内表面的一部分可以形成第一限位槽16a的槽壁，密封部件41高度方向的一端部位于该第一限位槽16a内，从而对密封部件41的装配位置进行限位，此时第一限位槽16a的宽度可以大于等于密封部件41径向方向的厚度。为加强阀体10的强度，可以在顶壁部13上设置多个连接筋，连接筋沿顶壁部13的径向排 布，也可以在顶壁部13上设置沿周向延伸的一圈连接筋，从而提高顶壁部13的结构强度。可选地，为了对平衡密封块42的位置进行限位，凸出部16还可以包括第二限位槽，第二限位槽的槽口与阀腔连通，平衡密封块42的高度方向的一端位于第二限位槽内，第二限位槽的宽度可以大于等于平衡密封块42径向方向上的厚度。
请进一步参阅图1至图3，当连通口还包括第二连通口321且阀体包括安装部14时，第二连通口321位于侧壁部11高度方向的一端且位于远离密封部件41的一侧，安装部14具有安装面141，在安装面141上，与第一连通口311连通的阀端口102、与第二连通口321连通的阀端口102均为矩形且截面积相等。通过上述设置，能够使通过每个阀端口102的流体流量趋近。
定义与第一连通口311连通的阀端口102为第一阀端口312，与第二连通口321连通的阀端口102为第二阀端口322，在安装面141上，第二阀端口322的长度大于第一阀端口312长度的二倍，阀体10的安装部14还可以包括加强筋142，加强筋142沿第二阀端口322的宽度方向延伸且连接于第二阀端口322的沿控制阀高度相对设置的两个表面之间。通过上述设置，能够提高控制阀1在各个阀端口102的强度，提高控制阀1的质量。
综上，根据本申请实施例提供的控制阀1，控制阀1包括侧壁部11，侧壁部11具有第一连通口311，第一连通口311沿侧壁部11的高度方向和侧壁部11的周向排布，且沿侧壁部11的周向，侧壁部11排布有两个第一连通口311，相较于将所有的第一连通口311均沿侧壁部11的周向排布，能够减小侧壁部11圆周方向的需要密封的区域，相应地，密封部件41的密封主体部410设置于侧壁部11和阀芯20之间，且密封主体部410具有与第一连通口311连通的通孔411，通孔411沿密封部件41的高度方向和密封部件41的周向排布，沿密封部件41的周向排布有两个通孔411，此时能够相对减小密封部件41的弧长，通过设置密封部件41的弧长对应的圆心角大于等于90度小于等于180度，相较于密封部件的弧长对应的圆心角大于180度，本申请实施例的密封部件41的弧长较小，能够降低产品模 具的制造难度，降低密封部件41以及控制阀1的制造成本，且能实现控制阀1的密封性能，便于推广应用。
