具体实施方式
请参阅图1至图5所示，所述流量控制装置100可应用于换热系统，比如车用空调系统或者家用空调系统等，具体地所述流量控制装置所流通的流通介质可为水、水与其他液体的混合液体或者其他具有导热能力的冷却液体，所述流量控制装置控制流通介质的分配并使流通介质与换热系统的其他工作介质进行热交换，再通过调节分配所述流量控制装置的介质出口流量来控制换热系统流路的流通介质，能够提升优化该换热系统流路的控制性能。
所述流量控制装置100设置于新能源汽车空调系统管路，能够用来实现空调系统的暖通流路、电池冷却流路与电池加热系统流路之间的切换，通过所述流量控制装置多通控制结构的设置，该流量控制装置将来自同一进口的工作介质按照比例分配到不同出口，所述流量控制装置可位于两个或多个换热系统回路，能够配合所述换热系统进行流路切换，且能够实现换热系统不同流路的工作介质流量比例分配。
所述流量控制装置包括包括壳体1、阀芯组件2与控制部件3，其中壳体包括分配主体11、盖体12，其中所述分配主体具有安装腔101，该安装腔101上侧具有安装开口，具体地可定义安装开口为分配主体上端口，所述阀芯组件2自所述安装开口置入该安装腔101，且至少部分收容于该安装腔，进一步所述分配主体11与所述盖体12相组装，具体地该分配主体11与所述盖体12分别设置有螺钉安装孔，可通过螺钉元件4将两者组装而实现相对固定设置，所述壳体1与控制部件3也通过螺纹连接方式进行组装。
所述壳体1具有至少一个进口、至少一个出口，本实施方式中壳体1具有第一管路、第二管路、第三管路，其中第一管路为进口管路102，第 二管路为第一出口管路103，第三管路作为第二出口管路104，从而所述壳体1具有进口1021、第一出口1031以及第二出口1041，形成一进两出的三通结构；具体地所述分配主体11与盖体12相配合而形成所述安装腔101，所述进口、第一出口以及第二出口能够与所在换热系统回路的连接管路相配合，具体地所述壳体的进口管路102、第一出口管路103以及第二出口管路104与该分配主体可以是一体形成结构。请结合图6到图8所示，所述阀芯组件2至少部分收容于所述安装腔101，所述阀芯组件2包括第一阀片21、第二阀片22以及传动部分23，所述壳体1具有位于所述安装腔底侧的限位凸部13、收容部1011，具体地限位凸部、收容部1011均具有扇形外轮廓，该收容部与所述限位凸部在壳体内互补设置，此处定义“互补设置”是针对壳体的底部区域而言，所述收容部占据该底部区域的一部分、且限位凸部占据该底部区域的另一部分，尤其从俯视角度来看，在壳体内底部区域范围内所述收容部与限位凸部互补设置。所述第一阀片21至少部分位于所述收容部1011，而限位凸部13能够对第一阀片进行周向限位，使得第一阀片21相对于壳体相对固定设置，此处定义“相对固定设置”是指第一阀片可在允许范围内运动，所述第一阀片21位于该收容部1011内从而能够与限位凸部13也大致成互补设置与所述限位凸部相对应地，所述第一阀片21大致呈扇形设置，可减少第一阀片的体积、降低材料成本，且所述第一阀片的下侧面与所述壳体直接接触而密封设置或者通过另外设置密封件进行密封，所述第一阀片的上侧面与第二阀片相接触，该第一阀片的下侧面与其上侧面背对设置，第二阀片的下侧面与该第一阀片接触，第二阀片的上侧面则与该第二阀片下侧面背对设置。为便于说明，此处定义与所述第一阀片21、第二阀片相垂直的方向为竖直方向，具体地该竖直方向与第一、第二阀片所在平面垂直，即第二阀片进行转动的中心轴线方向、也可理解为所述安装腔的轴线方向或者传动部分的轴线方向，所述第一阀片21的下侧面低于所述限位凸部13的上侧面131，所述第一阀片的上侧面高于或相平于所述限位凸部13的上侧面，所述第二阀片的下侧面与该限位凸部的上侧面至少部分相对设置，在所述竖直方向上，所述第二阀片的下侧面与所述限位凸部的上侧面之间具有间隙，该间隙不大于所述第一阀片的厚度尺寸，具体地，所述第一阀片的厚度尺寸为 3mm～9mm，比如4mm、5mm、6mm、7mm等尺寸，该第一阀片过薄，不易制造成型且结构强度差，过厚会相对增加整体产品高度尺寸，不利于小型化且原材料成本相对增加。
所述限位凸部13两侧分别形成第一止挡部132、第二止挡部133，该第一止挡部、第二止挡部形成于限位凸部两侧的侧边区域，该侧边区域与限位凸部上侧面131相交叉设置，且该第一止挡部和/或第二止挡部用于与第一阀片的侧边相对设置，第一阀片21具有第一抵接部2101、第二抵接部2102，对第一阀片而言，该第一阀片具有外形为扇形的主体部210，该主体部包括弧形部，该弧形部与所述第一、第二抵接部成扇形设置。所述第一抵接部2101与第一止挡部132相对设置，第二抵接部2102与第二止挡部133相对设置，从而所述第一、第二止挡部能够对所述第一阀片进行周向限位，具体地，所述第一阀片21与所述限位凸部之间允许存在间隙，即所述第一阀片21与所述壳体之间为间隙配合，所述第一抵接部2101与所述限位凸部的第一止挡部132之间具有间隙，该间隙小于2mm，和/或，所述第二抵接部2102与第二止挡部133之间具有间隙，该间隙小于2mm,所述第一阀片21与壳体的限位凸部13两侧采取以上间隙配合，使得第一阀片21便于安装到壳体内，同时也不影响第一阀片与第二阀片之间密封性能。
所述第二阀片22的下侧面至少部分与所述限位凸部的上侧面131相对设置，在所述竖直方向上，所述第二阀片22的下侧面与所述限位凸部的上侧面131至少部分相对设置，所述第二阀片下侧面与所述限位凸部的上侧面131之间具有间隙，该间隙小于0.8mm,此设置方式可减少所述第二阀片相对于第一阀片转动过程中所受摩擦阻力，保证第二阀片活动性能，另外，所述限位凸部13的上侧面131形成大致为扇形的限位面，当第一阀片21受第二阀片向下压力或者流通介质施加的向下压力时，必要时限位凸部的上侧面能够提供限位，有利于提升第二阀片动作的稳定性；所述第二阀片22的下侧面沿第一阀片上表面往复转动，也就是说，所述第二阀片为可动阀片，相对于该第二阀片所述第一阀片作为相对固定阀片，所述第二阀片沿第一阀片的上侧面进行回转运动，这种往复转动的动作方式相对于直线型往复动作方式，在保证开关流通阀口同时可缩减动作行程所需要的空间， 有利于产品体积。所述第二阀片22的下侧面的粗糙度小于或等于该第二阀片的上侧面，所述第一阀片21的上侧面的粗糙度小于或等于该第一阀片的下侧面，其中第一阀片的上侧面、第二阀片的下侧面作为接触摩擦面，粗糙度要求相对较高，经过多次设计及反复测试，所述第一阀片的上侧面的表面粗糙度大于0.03μm小于0.5μm，和/或所述第二阀片的下侧面的表面粗糙度大于0.03μm小于0.5μm，比如表面粗糙度为0.03μm、0.04μm、0.05μm、0.06μm、0.07μm、0.08μm、0.09μm、0.1μm、0.2μm、0.3μm、0.4μm、0.45μm、0.485μm或者上述范围内其他任意数值，可保证第一、第二阀片之间密封，比如对液体流通介质实现内密封，防止内漏而影响对流通介质进行控制性能，相对地，第一阀片的下侧面、第二阀片的上侧面作为非摩擦面，粗糙度要求相对较低，以降低制造成本。
所述第一、第二阀片均为陶瓷阀片或金属阀片，从而各阀片高耐磨性、高熔点、高硬度，在高温下不易氧化，比如陶瓷阀片且对酸、碱、盐具有良好的抗腐蚀能力，因此，在长时间不同温度下反复使用，陶瓷阀片或金属阀片能保持良好的密封效果，相对于橡胶材质不容易出现老化现象，可保证流量控制装置性能；进一步所述第一、第二阀片分别作为上、下阀片，各自外形采用扇形设置，两者的相对接触面积较小，可以减少两者间的摩擦力，从而降低对电机的扭矩要求，防止摩擦力过大而导致流量控制装置无法运动，同时也有利于降低成本、减轻产品整体重量。
所述壳体1的分配主体11具有位于安装腔底侧的至少一个流通孔，该至少一个流通孔与所述至少一个出口相连通，所述第一阀片21具有与壳体的流通孔相对应连通的至少一个流通阀口，所述流通阀口的数量等于或不等于所述流通孔的数量，比如第一阀片21设置一个流通阀口时，所述壳体的流通孔可为一个或两个，或者比如所述第一阀片21设置两个流通阀口时，所述壳体的流通孔可为一个或两个，具体可根据需要进行成型制造，应用中也可根据系统管路的需要增加或减少所述流通阀口与所述流通孔的数量，所述第二阀片22包括扇形开口220，该扇形开口与该第一阀片的流通阀口部分对准导通时，即可打开其中一个出口，所述第二阀片22与所述传动部分23相对固定连接，所述流量控制装置的控制部件3能够提供驱动力，该驱动力带动所述传动部分23进行动作，通过所述传动部分23来带 动所述第二阀片22，所述传动部分23上端与控制部件机械连接，且该上端与壳体1之间为密封设置，所述第一阀片的上侧面与第二阀片的下侧面相接触；在所述传动部分23带动下，所述第二阀片22打开、关闭所述第一阀片的流通阀口、和/或调节所述流通阀口的开度大小；另外，在竖直方向上，所述第二阀片22的下侧面与所述限位凸部13相对设置，且该第二阀片22下侧面与第一阀片上侧面相接触，使得该流量控制阀的工作介质流经流通阀口，防止工作介质从第一、第二阀片之间泄露。
请参考图4到图10所示，所述壳体的流通孔包括位于安装腔底侧的第一流通孔111、第二流通孔112，所述壳体的第一出口与第一流通孔相连通，该第二出口与第二流通孔相连通，所述第一阀片21的流通阀口包括与第一流通孔相对应连通的第一流通口211、与第二流通孔相对应连通的第二流通口212，具体地，所述第一阀片具有隔离部214，其中该隔离部一体形成于扇形主体部内侧，所述第一流通口211、第二流通口212形成于所述隔离部214两侧，从而所述流量控制装置具有流通通道，该流通通道能够连通所述进口管路102与所述第一、第二出口管路中至少一个。在所述传动部分23带动下，所述第二阀片22能够打开所述第一阀片21的第一流通口211和/或第二流通口212，所述第二阀片的扇形开口220与第一流通口211和/或第二流通口212连通，通过打开第一流通口211能够实现所述壳体的进口管路与第一出口管路导通，通过打开第二流通口212能够实现所述进口管路与第二出口管路导通，所述传动部分23能够控制所述第二阀片作回转运动，从而调节所述进口管路分配到所述第一出口管路与第二出口管路流量比例，具体地当所述第一、第二流通口同时打开，所述第一流通口211的开度增加时，所述第二流通口212的开度减小，或者所述第二流通口212的开度增加时，所述第一流通口211的开度减小。
另外结合图2所示，所述壳体1的分配主体11形成有分隔部113、第一分配腔114与第二分配腔115，所述分隔部113从壳体底侧一体延伸设置，该分隔部与所述限位凸部13一体形成，所述第一分配腔114与第二分配腔115分别位于该分隔部113两侧，其中壳体的第一流通孔111与所述第一分配腔114相通，所述第二流通孔112与所述第二分配腔115相通，从而可分配工作介质从第一、第二流通孔流入各自对应的第一、第二分配 腔；进一步，所述第一分配腔114底侧形成有第一导流部1141，该第一导流部具有与所述隔离板的一侧壁面连接的弧形连接面，和/或所述第二分配腔115底侧形成有第二导流部1151，该第二导流部具有与所述隔离板的另一侧壁面连接的弧形连接面，可导引工作介质顺利通过、尽可能地减少流体阻力。
具体地，通过所述第二阀片22相对于第一阀片在第一位置与第二位置之间动作，当第二阀片22位于第一位置时，该第二阀片打开第一流通口211、第一出口管路103导通，并且关闭第二流通口212、第二出口管路104截止导通，当第二阀片22位于第二位置时，该第二阀片打开第二流通口212、第二出口管路104导通，并且关闭第一流通口211、第一出口管路103截止导通。进一步，在第二阀片22动作过程中，当所述第二阀片22到第一位置时，所述第一流通口211打开到最大开度、所述第二流通口212的开度为零，此时该第一流通口的通流面积达到最大、该第二流通口的通流面积达到最小；当所述第二阀片22到第二位置时，所述第一流通口211的开度为零、所述第二流通口212打开到最大开度，此时第一流通口的通流面积达到最小、第二流通口的通流面积达到最大；当所述第二阀片22动作到第一、第二位置之间时，所述第一流通口211、第二流通口212同时打开，所述第一流通口211的开度与所述第二流通口212的开度之和等于所述第一流通口的最大开度或者第二流通口的最大开度，即两者通流面积之和等于第一、第二流通口任意一个的最大通流面积，从而所述流量控制装置能够实现对工作介质进行比例分配，且第一、第二阀片之间密封设置，可极大程度上提升产品密封性能，防止工作介质从第一、第二阀片之间泄露；所述壳体的第一流通孔111、第二流通孔112成扇形或月牙形或腰子形设置，相对应第一流通口211、第二流通口212成扇形或月牙形或腰子形设置，随着第二阀片第一、第二流通口的流通面积的增加或减小过程中，工作介质流量逐步增加或减小，在流通阀口关闭或打开过程中，能够较好的使开阀特性与关阀特性保持相对一致，在系统运行时，进行系统流量调节时性能较稳定。
所述流量控制装置还包括整体大致呈扇形的密封件24，该密封件位于所述收容部1011，且该密封件与第一阀片21相对应设置，两者位于与所 述限位凸部13互补的区域，具体地，且该密封件与第一阀片21安置于收容部1011，所述密封件24形成有第一通孔241、第二通孔242，第一通孔241、第二通孔242成扇形或月牙形或腰子形设置，所述第一通孔241与壳体的第一流通孔111对应设置，所述第二通孔242与壳体的第二流通孔112对应设置，或者，所述第一通孔241与第一阀片的第一流通口211对应设置，所述第二通孔242与第一阀片的第二流通口212对应设置，方便工作介质顺利通过、减少流体阻力；所述密封件24分别抵接接触壳体1底壁与第一阀片21，其中该密封件24与所述第一阀片21的下侧面相接触、且与壳体相接触，从而实现密封，在垂直于所述第一阀片的竖直方向上，所述密封件夹设在所述第一阀片的下侧面与所述壳体之间，所述壳体具有收容所述密封件的定位凹槽1012，该定位凹槽与密封件24相对应设置，防止工作介质从壳体与第一阀片之间泄露。
请参考图3、图7、图8所示，所述传动部分23一端形成第一传动部231，该第一传动部与第二阀片22的上侧面相对固定，第二阀片22的上侧面具有收容该第一传动部的固定凹部221，所述传动部分另一端形成第二传动部232，该第二传动部232向壳体外延伸设置，即，所述第一传动部231与第二传动部232位于该传动部分相对两端，具体地，所述壳体1的盖体12具有与所述第二传动部232对应设置的通孔121，所述第二传动部穿过该通孔向外延伸；请继续参考图11、图12所示，所述流量控制装置还包括转接件5，该转接件5设置于所述壳体外侧，其中转接件一端与所述第二传动部232通过凹凸结构进行组装而实现相对固定，转接件另一端与所述控制部件3的传动输出部31通过内外花键相配合组装而实现相对固定，通过设置所述转接件可将传动部分、控制部分的传动输出部相互组装而实现相对固定，能够提升传动部分23动作可控性，具体地所述转接件5包括主体部50、限位部51与转接传动部52，其中主体部50与第二传动部232相对组装，限位部51自该主体部50呈径向悬伸状设置，且该限位部51布置在该主体部中心轴线的部分周侧，所述转接传动部52与传动输出部31机械连接。
