【具体实施方式】
为了更好地详细理解本申请提供的电磁换向阀结构的详细技术方案,下面结合说明书附图进行详细陈述本申请提供的电磁换向阀结构的第一种实施方式,参照图16和图17所示,图16为本申请提供的电磁换向阀的立体示意图,图17为图16的侧向立体示意图,电磁换向阀包括阀体部,阀体部包括阀体主体部10、第一套筒部40以及第二套筒部50,第一套筒部40和第二套筒部50位于阀体主体部10的不同侧,第一套筒部40与阀体主体部10固定连接,第二套筒部50与阀体主体部10的固定连接,至少部分第一套筒部40为圆筒状结构,至少部分第二套筒部50为圆筒状结构,阀体主体部还包括板状部11和围绕部12,板状部11与围绕部12固定连接或为一体加工成型结构,围绕部12设有第一连接口部121,板状部11设有至少两个第二接口部111,沿电磁换向阀的X-X'方向,板状部11位于阀体主体部的底部,围绕部12围绕所述板状部11设置,阀体主体部10的纵截面积与第一套筒部40的纵截面积不同,且阀体主体部10的纵截面积与第二套筒部50的纵截面积不同,阀体主体部的最大纵截面积所围合的面积大于第一套筒部40的纵截面积所围合的面积,阀体主体部的最大纵截面积所围合的面积大于第二套筒部50的纵截面积所围合的面积,通过对电磁换向阀结构的改进,包括阀体主体部、第一套筒部以及第二套筒部,相对背景技术的电磁换向阀结构阀体部采用圆筒状结构,需采用曲面状结构实现与D型阀座部进行配合,本申请的阀体主体部包括板状部和围绕部,板状部与围绕部固定连接或为一体加工成型结构,板状部能够与滑块滑动配合,此外整体方便了阀体部的加工,阀体主体部10的内腔设置的相对较大,可匹配商用类制冷系统的大机型结构,而两端采用第一套筒部和第二套筒部,则仍然可保持不变匹配较小的老机型结构,两侧的第一套筒部以及第二套筒部的尺寸大小可灵活调整,并能够采用较小的尺寸实现与阀体主体部10的连接,能够实现零部件降成,从而实现阀体部结构的整体降成。
本申请提供的电磁换向阀可为三通式的电磁换向阀结构,也可以是五通式的电磁换向阀结构,本实施例中以三个接口部,为四通式的电磁换向阀结构作为示例进行说明,参考图18-图20所示,本实施例中的阀体主体部10采用成型的管件一体成型,例如可采用不锈钢型材,本实施例中以方体形的阀体主体部结构为示例进行说明,阀体主体部包括板状部11和围绕部12,板状部11和围绕部12为一体加工成型结构,沿电磁换向阀的X--X'方向,板状部11位于阀体主体部10的底部,形成阀体主体部的底壁,围绕部12以板状部11为基准面围绕设置,围绕部12罩盖板状部11,第二接口部包括三个连接口部,板状部11设有E连接口部、S连接口部以及C连接口部,围绕部12设有第一连接口部即D连接口部,E连接口部、S连接口部以及C连接口部三者可并列设置,D连接口部可与E连接口部、S连接口部以及C连接口部三者相对设置,板状部11包括第一翻边部111、第二翻边部112以及第三翻边部113,第一翻边部111、第二翻边部112以及第三翻边113部沿电磁换向阀的X--X'方向向下翻边成型以分别对应形成E连接口部、S连接口部以及C连接口,阀体主体部还包括第四翻边部114,第四翻边部114向上翻边成型以对应形成D连接口部,对应地电磁换向阀还包括第一接管以及第二接管,第一接管与第二接管均可采用不锈钢材质制成,第一接管对应D连接口部,第二接管对应E/S/C连接口部,第一接管即D接管与D连接口部固定连接,第二接管即E/S/C接管与E/S/C连接口部分别固定连接,阀体主体部围绕部12至少包括一个板状部结构,需要说明的是根据满足流体应力需求,如图21所示的阀体主体部10的结构,也可以将围绕部12的顶壁设置成具有一定弧度的弧面状结构以加强阀体主体部整体对流体的应力作用,或者围绕部12的两边的侧壁也可以设置成具有一定弧度的弧状面结构或其他结构,本实施例中所陈述的阀体主体部为方体形结构,方体形结构包括长方体、正方体、梯形以及其他异型结构,如图22所示的为阀体主体部10为梯形结构状态,需要说明的是本实施例中的阀体主体部10除了用型材直接制成外,也可以如图6所示的采用整块板料件进行展开式,先进行冲孔形成D连接口部以及E/S/C连接口部,以板状部11为基准面,进行翻边折叠后的折叠壁的末端端部与板状部11 通过激光焊等方式实现焊接固定,本实施例提供的阀体主体部整体可由型材一体成型,或者由板料件进行折叠后焊接成型,相对比背景技术的阀体部需要对阀体的胚体进行一系列金加工的拉制、整个内周壁的粗糙度打磨等加工工序而言,更便于阀体主体部的加工,能够相对减少工序降低产品加工成本。
并且通过上述设置,相较于背景技术D型棒的阀座部与阀体的曲面部相配合,因曲面空间有限,阀座部的宽度要小于阀体内径,而E/S/C接管的直径要小于阀座部的尺寸,当E/S/C接管的尺寸加大后,因受曲面空间的影响,焊接长度变小,接管规格匹配受限,本申请通过对电磁换向阀结构的优化设计,阀体主体部包括板状部以及围绕部,使E/S/C接管与板状部11配合连接,阀体主体部接管规格尺寸可灵活匹配应用,不受限制,接管的通径可相对加大,提升阀容量,此外阀体主体部10整体可由钢管件一体成型,方便阀体主体部的整体加工,相对降低了产品零部件的加工成本,
