具体实施方式
下面结合附图和具体实施方式对本发明作进一步说明:
在以下的实施方式说明中,为了便于理解,适当地使用表示方向的用语(例如“上方”、“下方”等),以电磁阀为例,定义线圈组件位于阀座的上方,以套管的轴线方向为电磁阀的轴线方向。
结合图1和图2,电磁阀100包括阀支撑件1、阀座2、线圈组件3、铁芯组件4以及阀部件5,阀支撑件1与阀座2固定连接或者限位连接,至少部分阀座2位于阀支撑件1的上方,至少部分阀部件5位于阀支撑件1和阀座2连接后所形成的腔。电磁阀100还包括套管6,部分套管6位于阀座2的上方,套管6的一端伸入阀座2所形成的孔,并与阀座2相对固定,固定方式可以是焊接或者粘接或者一体设置。至少部分铁芯组件4位于套管6的内周,具体地,铁芯组件4包括静铁芯41和动铁芯42,至少部分静铁芯41设置于套管6内并与套管6的内壁相对固定,固定方式可以是焊接或者铆接,至少部分动铁芯42设置于套管6内,动铁芯42能够相对静铁芯41沿套管6的轴向动作,在本实施方式,动铁芯42比静铁芯41靠近阀座2,在其他实施方式,也可以是静铁芯41比动铁芯42靠近阀座2。 线圈组件3套设于套管6的外周,具体地,线圈组件3包括线圈部31和导磁体32,线圈部31和导磁体32卡接固定,线圈部31和导磁体32均设有贯通孔,并且线圈部31的贯通孔和导磁体32的贯通孔同轴设置,套管6位于线圈部31的贯通孔和导磁体32的贯通孔内。在一种具体的实施方式,线圈组件3通过螺钉7与静铁芯41螺纹固定,以实现线圈组件3和铁芯组件4的限位连接,当然,在其他实施方式,线圈组件3还可以通过卡接件实现与铁芯组件4的限位连接。
结合图2、图3、图4、图5和图6,电磁阀100包括阀腔102,形成阀腔102的壁至少包括阀支撑件1的内壁和阀座2的内壁。电磁阀100还具有第一通道11、第二通道12和阀口13,其中,第一通道11、第二通道12和阀口13成形于阀支撑件1。具体地,第一通道11贯穿阀支撑件1的侧部,第一通道11在阀支撑件1的侧部形成有两个开口,其中一个开口位于阀支撑件1的外壁,另一个开口位于阀支撑件1的内壁,或者说,另一个开口位于形成阀腔102的壁,第一通道11与阀腔102连通;第二通道12成形于阀支撑件1的底部,第二通道12在阀支撑件1的底部形成有开口,进一步说,第二通道12在阀支撑件1的下壁形成有开口,阀口13成形于阀支撑件1底部的上壁,在阀口被打开时,第二通道12能够通过阀口13阀腔102连通。
在其他实施方式,第一通道11也可以成形于阀座2,第一通道11在阀座2的侧部形成有两个开口,如图13所示,不再详细描述。当然,阀支撑件1或阀座2的侧部可以成形有多个第一通道11,第一通道11沿阀支撑件1或阀座2的侧部周向分布设置,以降低冷媒进入阀腔102的流阻。
阀部件5位于阀腔102,至少部分阀部件5能够在阀腔102内沿套管6的轴向动作,具体地,阀部件5包括阀芯51,阀座2包括导向部205,阀芯51包括滑动部502,在阀芯51动作时,滑动部502与导向部205滑动配合,以防止阀芯51偏离套管6的轴线运动。阀部件5还包括弹性元件52,阀支撑件1还包括支撑部15,其中,支撑部15成形于阀支撑件1底部的上壁,支撑部15沿第二通道12的周向分布设置,沿套管6的轴向,弹性元件52的一端与阀芯51抵接,弹性元件52的相对另一端与支撑部15抵接,这样,支撑部15为弹性元件52提供支撑,弹性元件52为阀芯51提供支撑,弹性元件52能够为阀芯51提供回复力。因为阀支撑件1与阀座2限位或者固定连接,阀部件5容置于阀腔102,这样,电磁阀100的各部件连接固定在一起形成一个整体件,有利于电磁阀100与其他部件快速安装,其他部件可以是带有冷媒流通通道的阀体。在本实施方式,弹性元件52为塔型弹簧,可以知道,弹性元件52也可以为圆柱形弹簧或其他结构,当然,弹性元件52也可以为材料包括聚氨酯的弹性元件或者其他弹性元件。更近一步,弹性元件52可以与阀芯5固定,弹性元件52也可以与支撑部15固定,固定方式可以为卡接或者焊接固定,以防止弹性元件52在电磁阀100工作时移位,进而提高电磁阀100的可靠性。此外,阀芯51在阀腔102内的移动过程中能够打开或关闭阀口13以控制电磁阀的通断,具体地,阀芯51打开阀口13时,阀腔102通过阀口13与第二通道12连通,进而实现第一通道11和第二通道12的连通;阀芯51关闭阀口13时,阀腔102与第二通道12不连通,进而第一通道11与第二通道12不连通。
结合图2、图4、图6、图10和图11,阀座2包括第一凹槽29,沿电磁阀100的轴向,第一凹槽29位于阀座2的靠近线圈组件4的一侧,第一凹槽29成形于阀座2的外壁,具体地,第一凹槽29成形于阀座2的侧壁,第一凹槽29在阀座2的侧壁具有开口,第一凹槽29相对阀座2的侧壁凹陷,第一凹槽29沿阀座2的侧壁周向设置,更进一步,电磁阀100还包括第一密封件80,至少部分第一密封件80设置于第一凹槽29,电磁阀100与其他部件安装后,阀座2与其他部件挤压第一密封件80,进而形成其他部件与阀座2的密封,如图10所示,其他部件可以是阀体200。
阀支撑件1包括第二凹槽19,沿电磁阀100的轴向,第二凹槽19位于阀支撑件1远离阀座2的一侧,第二凹槽19成形于阀支撑件1的外壁,具体地,第二凹槽19成形于阀支撑件1的侧壁,第二凹槽19在阀支撑件1的侧壁具有口,第二凹槽19相对阀支撑件1的侧壁凹陷,第二凹槽19沿阀支撑件1的侧壁周向设置,更进一步,电磁阀100还包括第二密封件90,至少部分第二密封件90设置于第二凹槽19,电磁阀100与其他部件安装后,阀支撑件1与其他部件挤压第二密封件90,进而形成其他部件与阀支撑件1的密封,如图10所示,其他部件可以是阀体200。
当然,在另一实施方式,第二凹槽19也可以成形于阀支撑件1的底壁,第二凹槽19在阀支撑件1的底壁具有口,第二凹槽19相对阀支撑件1的底壁凹陷,第二凹槽19沿第二通道12的周向设置,第二密封件90设置于第二凹槽19,进而第二密封件90与阀体200抵接,以实现电磁阀100与阀体200的密封,可以知道,在该实施方式中,第二密封件90与第二凹槽19过盈配合,或者,第二密封件90通过橡胶硫化工艺与第二凹槽19嵌为 一体,这样,能够防止第二密封件在安装时滑落,提高安装效率,同时也能够增强密封性能,如图12所示。可以知道,沿电磁阀100的轴向方向,第一通道11位于第一凹槽29和第二凹槽19之间,这样有利于防止冷媒在电磁阀100的工作时产生泄漏。
结合图2、图4和图6,阀支撑件1与阀座2的下端固定连接,具体地,阀支撑件1包括第一安装部10,第一安装部10成形于阀支撑件1的外壁,第一安装部10位于阀支撑件1相对靠近阀座2的一端,或者说,第一安装部10位于阀支撑件1的上端部,相应地,阀座2包括第二安装部20,第二安装部20成形于阀座2的外壁,第二安装部20位于阀座2靠近阀支撑件1的一端,或者说,第二安装部20位于阀座2的下端部,第一安装部10与第二安装部20配合以固定连接或者限位连接,第一安装部10与第二安装部20的连接处位于第一凹槽29和第二凹槽19之间,这样,无需考虑第一安装部10与第二安装部20之间的密封问题,相对简化电磁阀100的结构以及减少电磁阀的零部件数量。在本实施方式,第一凹槽29成形于阀座2,第一凹槽29与阀体200配合形成密封,相比于第一凹槽29成形于阀支撑件1,这样电磁阀100的整体径向尺寸减小,有利于电磁阀的小型化;阀支撑件1连接固定于阀座2的下端,这样,有利于减小电磁阀100的轴向长度,从而有利于电磁阀100的小型化。可以知道,沿电磁阀100的轴线方向,当第一通道11成形于阀座2时,第一通道11位于第一凹槽29和第二安装部20之间,或者说,第一通道11比第二安装部20远离阀支撑件1,如图2所示;当第一通道11成形于阀支撑件1时,第一通道11位于第一安装部10和第二凹槽19之间,或者说第一通道11比第一安装部 10远离阀座2,如图13所示,这样有利于使冷媒流动更加稳定。
此外,第一安装部10与第二安装部20可以有多种不同的连接方式,有利于提高电磁阀100的实用性。在第一种实施方式,结合图2和图7,阀支撑件1与阀座2通过螺纹连接以相对固定。具体地,第一安装部10成形为第一内螺纹101,第二安装部20成形为第一外螺纹201,其中,第一内螺纹101位于阀支撑件1的内侧壁,第一外螺纹201位于阀座2的外侧壁,在第一内螺纹101和第一外螺纹201的作用下,第一安装部10与第二安装部20螺纹连接,从而实现阀支撑件1与阀座2的可拆卸连接。当然,在其他实施方式,第一安装部10也可以成形为第一外螺纹102,第一外螺纹102位于阀支撑件1的外侧壁,第二安装部20也可以成形为第一内螺纹101,第一内螺纹101位于阀座2的内侧壁,第一安装部10与第二安装部20螺纹连接,不再详细描述。
在第二种实施方式,结合图2和图8,阀支撑件1与阀座2通过卡接以相对固定。具体地,第一安装部10成形为第一凸部102,第二安装部20成形为第一凹部202,其中,第一凸部102位于阀支撑件1的内壁并且第一凸部102沿着第一安装部20的周向分布,第一凹部202位于阀座2的侧壁并且第一凹部202沿着第二安装部20的周向分布,第一凸部102容置于第一凹部202,第一安装部10与第二安装部20形成卡接,从而实现阀支撑件1与阀座2的可拆卸连接。当然,在其他实施方式,第一凸部102也可以设置于第二安装部20,第一凹部202也可以设置于第一安装部10,即第一安装部10成形为第一凹部202,第二安装部20成形为第一凸部102,不再详细描述。
在第三种实施方式,结合图2和图9,阀支撑件1与阀座2焊接固定。具体地,第一安装部10具有第一抵接面103,第二安装部20具有第二抵接面203,其中,第一抵接面103成形于阀支撑件1的外壁,第二抵接面203成形于阀座2的外壁,第一抵接面103与第二抵接面203相对设置,第一抵接面103与第二抵接面203抵接,并在两者的抵接面注入焊料进行焊接固定,从而实现阀支撑件1与阀座2的固定连接。在其他实施方式,可以在第一抵接面103与第二抵接面203的抵接面注入固定胶进行粘接固定。当然,也可以将橡胶硫化到第一抵接面103和第二抵接面203之间,利用橡胶的粘合力实现阀支撑件1与阀座2的固定。在其他实施方式,阀座2与支撑件1也可通过铆接或者螺钉连接的方式进行固定,不再详细描述。阀支撑件1与阀座2采用焊接的固定方式,可以不用改变阀座2的结构,在实际生产运用中,可以利用常规电磁阀的阀座来进行组装适配,这提高了电磁阀100的实用性,有利于进一步提高生产效率。
本发明本技术方案的一个实施方式还提供一种电磁阀组件,电磁阀组件包括电磁阀100和阀体200,电磁阀100与阀体200固定或者限位连接,具体地,电磁阀100包括连接部21,连接部21成形于阀座2,电磁阀通过连接部21与阀体200固定连接或者限位连接。参见图10,阀体200包括容纳部201、第一孔道202和第二孔道203,至少部分电磁阀100位于容纳部201所形成的容纳腔,第一孔道202与第一通道11连通,第二孔道203与第二通道12连通,容纳部201包括限位部204,限位部204与连接部21配合以固定或限位电磁阀100。在该实施方式,沿电磁阀100的轴线方向,连接部21位于第一凹槽29和第二安装部20之间,连接部21成形为第二 外螺纹210,限位部204成形为第二内螺纹2040,第二内螺纹2040与第二外螺纹210相配合,电磁阀100安装于阀体200,这样能够简化安装步骤,操作简单,实现电磁阀的快速安装,方便电磁阀的维修及更换;可以知道,电磁阀100与阀体200也可以通过焊接等不同方式进行固定连接。
在本发明技术方案的另一个实施方式中,参见图11,与上一种实施方式的主要区别在于:限位部204包括第一子限位部2041和第二子限位部2042,连接部21包括卡簧211,卡簧211与电磁阀100分体设置,电磁阀组件通过卡簧211将电磁阀100固定于阀体200。具体地,阀体200包括第一凹部205,第一子限位部2041成形为第一凹部205的上壁;第二孔道203在容纳部201的底壁具有第一孔口2031,第二子限位部2042成形为容纳部201的底壁且沿第一孔口2031周向分布。
至少部分卡簧211位于第一凹部205,卡簧211的至少部分上端面与第一子限位部2041抵接,卡簧211的至少部分下端面与阀座2的上壁抵接。卡簧211的上端面与第一子限位部2041抵接,以防止电磁阀背向阀支撑件1移动,卡簧211的下端面与阀座2的上壁抵接,有利于卡簧211对电磁阀100施加向下的力,有利于电磁阀100与阀体抵接。阀支撑件1还包括抵接部18,抵接部18位于阀支撑件1远离阀座2的一侧,抵接部18比第二凹槽19靠近阀座2,抵接部18与第二子限位部2042抵接,以限制电磁阀100朝向第二孔道203方向移动。
卡簧211在径向方向具有弹性,这样卡簧211的侧壁与第一凹部205的侧壁抵接,可以使卡簧211相对固定,更进一步的,卡簧211也可以在轴向方向具有弹性,这样卡簧211对电磁阀100向下施加预紧力,能够使 电磁阀100与阀体200的固定更加稳定。电磁阀组件通过设置卡簧使电磁阀100安装于阀体200,这样能够简化安装步骤,操作简单,方便电磁阀组件的维修及更换。
或者,在其他实施方式,卡簧211也可以替换为压紧螺母,电磁阀组件通过压紧螺母将电磁阀100固定于阀体200。或者,电磁阀100在阀座设置法兰连接结构,电磁阀100与阀体200法兰连接,不再详细描述。
以上所述实施方式的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施方式的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明记载的范围。
以上实施方式仅用于说明本发明而并非限制本发明所描述的技术方案,尽管本说明书参照上述的实施方式对本发明已进行了详细的说明,但是,本领域的普通技术人员应当理解,所属技术领域的技术人员仍然可以对本发明进行修改或者等同替换,而一切不脱离本发明的精神和范围的技术方案及其改进,均应涵盖在本发明的权利要求范围内。
