本发明提供一种电动调节阀，可以应用于各种管路中，如应用于空调系统的水管或者冷媒管路或热水管路中。如图1-3所示，本发明电动调节阀包括执行器100和与执行器100相配合的调节阀200，执行器100驱动调节阀200的阀杆210在第一位置与第二位置之间移动，控制管路的通断。如图2所示，阀杆210移动至第一位置时，阀杆210与调节阀200的阀座220的阀口分离，阀座220的进口、出口连通，调节阀200切换至打开状态，流体可以通过调节阀200在管路中流动；如图3所示，阀杆210移动至第二位置时，阀杆210封堵阀座220的阀口，断开阀座220的进口、出口，调节阀200切换至闭合状态。
请同时参阅图1-3，执行器100包括电机20、与电机20连接的减速传动机构40、销轴60以及销盖80。
电机20作为整个执行器100的动力源，可以是现有的直流无刷电机，也可以是有刷电机等，在此对其结构不做赘述。电机20的控制端可以通过控制器等与传感器连接，构成自动控制回路。传感器可以是压力或温度传感器等，用于检测管道中流体的压力或环境温度数据；控制器根据传感器的检测结果产生相应的控制信号给电机20，电机20根据控制信号进行启停、转速调整或者转向调整，进而调整管道中的流体开口和流量。电机20包括一输出轴21，输出轴21的末端伸出电机20的壳体之外与减速传动机构40连接。
减速传动机构40包括传动连接的减速单元41和传动单元43，减速单元41与电机20的输出轴21连接，将电机20的高速转动转化为低速转动；传动单元43与销轴60连接，将减速单元41的低速转动转化为销轴60的线性移动。
减速单元41为行星轮减速结构，包括具有内齿圈的齿轮箱412以及设置于齿轮箱412内的多级行星轮414和太阳轮416，其中第一级的行星轮414与输出轴21通过第一级太阳轮416啮合传动，最末一级的行星轮414连接于一输出轮418。电机20转动时，其输出轴21经过减速单元41的减速后，最末一级的行星轮414以远小于电机20的速度转动。本实施例中，输出轮418与太阳轮416及电机20的输出轴21同轴设置，输出轮418的一端作为连接端、另一端作为输出端，其中连接端固定连接于最末一级行星轮414的转轴并随最末一级行星轮414沿内齿圈低速转动，输出端形成有一圈第一外齿，用于与传动单元43连接。
传动单元43为螺合传动结构，包括固定座432和与固定座432螺合连接的传动件434，其中传动件434包括第一传动部436和第二传动部438，第一传动部436为圆盘状，形成有一圈第二外齿，第二外齿与输出轮418的第一外齿相啮合，使得输出轮418可以带动传动件434转动；第二传动部438为螺柱，由第一传动部436的中央沿轴向向外延伸，固定座432内形成有螺孔433与第二传动部438相螺合，使得传动件434在转动的同时沿着其轴向线性移动。按图示方向，电机20沿某一方向（如顺时针方向）转动时，驱动传动件434沿其轴向向上移动；电机20反向（如逆时针方向）转动时，驱动传动件434沿其轴向向下移动。在本实施例中，螺孔433可存储润滑脂，利于传动单元43的转动和上下移动。
本实施例中，电机20与减速单元41同轴设置，电机20的壳体与齿轮箱412固定连接在一起；传动单元43偏置于电机20、减速单元41的一侧，与调节阀200的阀杆210同轴设置。减速单元41的齿轮箱412与传动单元43的固定座432左右并排布置，固定座432内的传动件434与齿轮箱412内的行星轮减速结构的轴线相平行，可以减小整个执行器100的轴向尺寸。较佳地，齿轮箱412与固定座432为一体成型，可以简化装配流程，也能有效避免组装时元件的公差或者误差的影响。齿轮箱412、固定座432上盖设有端盖45，端盖45与齿轮箱412、固定座432共同构成减速传动机构40的壳体。端盖45上设置有穿孔452，阀杆210通过穿孔452与销盖80相抵接。
销轴60包括相对的第一端62和第二端64，第一端62作为传动端，与传动件434固定连接；第二端64作为驱动端，与销盖80连接。本实施例中，传动件434的中央形成安装孔，安装孔由第一传动部436的外端面沿轴向向内延伸一定深度，销轴60的第一端62固定插接于安装孔内，使得传动件434能够带动销轴60随之同步移动和转动。销轴60的第二端64伸出至安装孔之外，销盖80罩设于第二端64上并随着销轴60移动。
销盖80整体上为帽盖状结构，包括基板81和由基板81的外边缘垂直延伸的环形侧板83，基板81与侧板83共同形成装配空间，销轴60的第二端64通过一连接元件66可转动地插接于装配空间中。基板81的内侧面812（面向销轴60的侧面）与销轴60的第二端64相抵顶、外侧面（背向销轴60的侧面）与阀杆210相抵顶，如此销轴60移动并转动时能够通过销盖80推动阀杆210随之同步移动，使得阀杆210能够在第一位置和第二位置之间切换。销盖80的基板81的尺寸大于阀杆210的端面的尺寸，使得阀杆210的整个端面能够与基板81相接触，阀杆210的移动更为平稳。销盖80的侧板83的外径可以略小于穿孔452的直径，方便销盖80在穿孔452中移动。
端盖45设置有沿轴向延伸的导向槽454，导向槽454由穿孔452壁面沿径向向外凹陷而成并与穿孔452相连通。销盖80的侧板83的外壁面突出形成有导向块832，装配时销盖80插入至端盖45的穿孔452中，导向块832滑动地插入至端盖45的导向槽454中，对销盖80在穿孔454内的移动形成导向作用，使得销盖80以及由销盖80推动的阀杆210的移动更为平稳。导向块832、导向槽454优选为多个，沿周向均匀间隔分布。另外，也可以在端盖45的穿孔452的壁面上突出形成导向块，对应地在销盖80的侧板83的外壁面凹陷形成导向槽，同样可以滑动配合对销盖80的移动起到导向作用。
相对于销轴60直接推动阀杆210，本发明通过销盖80将销轴60与阀杆210隔开，可以有效减小销轴60与阀杆210直接接触时由于相对转动等产生的碰撞与摩擦，减小噪音的产生，提升传动效率和传动的稳定性，使得阀杆210的移动能够更为精准。较佳地，基板81的内侧面812为外凸的弧面或部分为外凸的弧面，使得销轴60的端面与基板81形成点接触，有效减小两者相对转动时的摩擦，进一步减少噪音的产生。
如图2所示，本发明电动调节阀处于打开状态时，传动件434下移至其第二传动部438与固定座432的螺孔433的底面相抵，销轴60以及销盖80随着传动件434下移，销盖80处于端盖45的穿孔452的底部。如图3所示，本发明电动调节阀处于闭合状态时，传动件434上移至其第二传动部438与螺孔433的底面分离，销轴60以及销盖80随着传动件434上移至销盖80到达端盖45的穿孔452的上部或顶部。
需要说明的是，本发明并不局限于上述实施方式，根据本发明的创造精神，本领域技术人员还可以做出其他变化，这些依据本发明的创造精神所做的变化，都应包含在本发明所要求保护的范围之内。
