具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1至图5所示，本申请的实施例提供了一种电动阀，包括：阀座10，阀座10具有端面11和卡槽12；阀体20，阀体20的一部分穿设在阀座10内，阀体20的另一部分凸出于端面11；线圈部30，套设在阀体20上，线圈部30和卡槽12分别位于端面11的两侧；连接部 40，连接部40包括连接件41和设置在连接件41上的支撑件42、卡接件43，其中，连接件41和线圈部30固定连接，支撑件42和端面11抵接，卡接件43和卡槽12卡接。
在本实施例中，阀体20一部分穿设在阀座10内，阀体20的另一部分凸出于端面11，这样设置便于线圈部30与连接部40与阀座10之间的对应设置。线圈部30位于端面11的上方，卡槽12位于端面11的侧下方，便于与线圈部30连接的连接部40与阀座10的连接。连接件41和线圈部30固定连接，支撑件42和端面11抵接，卡接件43和卡槽12卡接，以实现连接部40与阀座10的固定连接。
采用该方案，在安装线圈部30时，将连接部40的卡接件43和阀座10上的卡槽12卡接即可，卡接完成后，支撑件42和阀座10的端面11抵接，这样可对线圈部30轴向的两个方向进行限位，从而实现了线圈部30和阀座10的可靠连接。采用该方案，在将线圈部30套入阀体20的同时就可实现连接，不需要拧螺钉，因此提高了装配效率，而且在振动环境中使用连接也不会松动。
具体地，支撑件42为具有弹性的结构。支撑件42采用弹性结构，在连接部40连接线圈部30和阀座10时能更好的起到支撑和限位作用，在固定线圈部30与阀座10之后也能更好的起到紧固作用。在装配和拆卸时，由于支撑件42可发生弹性变形，这样可便于将卡接件43卡入到卡槽12内或从卡槽12内取出。
进一步地，支撑件42包括相互连接的弧形板44和限位板45，弧形板44和连接件41连接，限位板45和端面11抵接，其中，限位板45和连接件41间隔开，限位板45相对于端面11倾斜设置。支撑件42采用弧形板44，可以在支撑件42抵接端面11时起到一个对二者抵接时产生的径向力缓冲的作用，保护支撑件42与连接件41之间的连接。此外，采用限位板45相对于端面11倾斜设置的方式，限位板45容易产生弹性变形，当支撑件42的限位板45抵接端面11时，可以起到良好的限位作用。
可选地，支撑件42为多个，多个支撑件42围绕阀体20设置。采用多个支撑件42共同作用，减小了每个支撑件42所承受的抵接时的压力，对整体连接部40起到保护作用，同时，支撑件42和阀座10配合后的紧固效果更好。
根据图3至图5所示，阀座10包括主体13和限位部14，端面11位于主体13，主体13具有台阶结构，限位部14位于台阶结构的侧面15，限位部14和台阶结构的底面16之间的区域形成卡槽12。通过上述结构设置，可在阀座10上形成卡槽12，以与连接部40配合。
在本实施例中，阀座10中的主体13具有台阶结构，限位部14位于台阶结构上并与台阶结构侧面15和台阶结构底面16之间形成卡槽12，这样设计便于卡槽12的加工和限位部14的放置，且可用主体13自带的台阶结构来构成卡槽，结构简单，加工方便。
具体地，限位部14具有限位槽17，限位槽17沿阀体20的轴向延伸；卡接件43包括连接板46和卡钩47，连接板46的两端分别和连接件41、卡钩47连接，其中，卡钩47和卡槽12卡接，连接板46和限位槽17限位配合。
其中，卡钩47与卡槽12卡接，连接板46与限位槽17限位配合，这样设计既方便了卡钩47与卡槽12卡接，同时通过连接板46与限位槽17的限位配合可在周向对连接板46进行限位，从而在周向对线圈部30进行限位。连接板46两端分别和连接件41、卡钩47连接，卡接完成后，支撑件42和阀座10的端面11抵接，这样可对线圈部30轴向的两个方向进行限位，从而实现了线圈部30和阀座10的可靠连接。
如图3和图4所示，连接部40还包括扳动件48，扳动件48和卡接件43的中部连接。人员在操作时，扳动扳动件48可带动卡接件43移动。扳动件48设置在卡接件43的中部，在卡接过程中可以起到一定的调节作用，以防止连接部40上的卡钩47不方便卡接或拆卸。
如图2所示，连接件41为环形结构，环形结构可避让阀体20，这样阀体20可穿过连接件41。连接件41上分布有多个通孔49，线圈部30具有多个凸柱31，多个凸柱31和多个通孔49一一对应地限位配合。采用这种配合方式，能更好的对线圈部30和连接部40进行限位，而且采用多个凸柱31和通孔49一一限位配合，更能保证结构的稳定性。其中，凸柱31和通孔49可采用铆接或焊接等方式固定连接。
具体地，连接部40为由金属材料制成的一体结构。连接部40由金属材料制成，具有较高的机械强度，从而可以提高阀座10和线圈部30的连接强度。连接部40可以设置为钣金件或冲压件，这样便于加工，成本低。
具体地，阀体20和阀座10螺纹连接。采用螺纹连接，安装容易，拆卸方便，操作简单。
如图4所示，连接件41与卡接件43的连接处设置凹陷结构。此种设计可避免卡接件43刚性太大导致安装拆卸不便的问题，提高弹性。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
