Description

阀座支承件
技术领域
本发明涉及一种根据权利要求1的前序部分所述的特别是用于电磁阀的阀座支承件。
背景技术
从文献EP 1 737 715 B1中已经已知一种可固定在电磁阀处的阀座支承件，其包括套筒状支承件壳体，在支承件壳体中固定由塑料制成的阀座体，阀座体具有空心圆柱形的轮廓。为了将阀座体固定在支承件壳体处，下部的套区段径向向内弯折成凸缘，该凸缘在两侧被嵌入阀座体的塑料中。
然而，以上阀座体在支承件壳体处的固定方案带来用于制造弯折的法兰的附加的材料需求，并且在将凸缘在两侧嵌入阀座体的塑料中的方面证实为不是特别有利。
发明内容
因此本发明的目标是，避免上述结构并且现在利用尽可能简单的、功能正确的器件成本适宜地且结构紧凑地实施所给出的类型的阀座支承件，其中，应以尽可能小的消耗将阀座体可靠地固定在支承件壳体处。
根据本发明，该目标通过权利要求1的特征所述的类型的阀座支承件实现。
附图说明
以下从对多个实施例的描述中得到本发明的其它特征和优点。
其中：
图1以透视图在纵截面中示出了根据本发明的阀座支承件的适宜的实施形式，
图2以透视图以看向其被倒角的端部区段的视线方向示出了根据图1的根据本发明的阀座支承件，该端部区段在外部设有三个在阀座支承件的周缘上均匀分布的盆形的凹入部，凹入部作为径向突出部小面积地伸入阀座支承件中，
图3以透视图以与图2相反地取向的视线方向示出了根据本发明的阀座支承件，从而可清楚地看出其凸缘状的、径向向外弯曲的凸缘。
具体实施方式
图1以显著放大图示出了根据本发明的阀座支承件，其包括套筒状支承件壳体1，在支承件壳体1中固定有塑料制成的阀座体3，阀座体3具有空心圆柱形的轮廓。
此外，可从图1中看到，阀座体3在其背离阀座4的端部区域处具有从支承件壳体1中突出的圆柱突出部7，弹性的密封环13被套到圆柱突出部7上直至在圆柱突出部7处的凸肩部14处。密封环13保证，在将阀座支承件装配在未示出的阀壳体中之后，气态的或液态的压力介质不能沿着阀座支承件的外轮廓渗入阀壳体中。
为了以尽可能小的消耗实现阀座体3在支承件壳体1中简单的但仍然可靠的固定，根据图2和3清楚地示出，支承件壳体1在其周缘处具有多个小面积的、径向向内指向的凹入部2，为了在支承件壳体1和阀座体3之间建立形状配合的连接，凹入部2作为在支承件壳体1处内部的径向的突出部11突出，相应于根据图1的图示，在阀座支承件的最终状态中，该径向突出部全面地被阀座体3的塑料包围。
如可从图2和图3中看出的那样，在支承件壳体1处设置至少三个盆形的凹入部2，其均匀地分布在支承件壳体1的周缘上。有利地，相应于根据图1的图示，凹入部2完全被阀座体3的塑料填充，从而在完成阀座体的制造之后，塑料与支承件壳体1的外壳齐平地终止。
为了尽可能简单的设计和将阀座体3在支承件壳体1处形状配合地固定，图2以俯视图示出了凹入部2连同由此得到的突出部11的布置方案，该突出部11直接设置在支承件壳体1的端部区段5处，该端部区段5设有漏斗形的倒角6，倒角6被凹入部2中断。倒角6以及凹入部2优选地在一个加工过程中通过由薄板制成的支承件壳体1的塑形变形制成。
由于使用薄板，可从所有图中看出的支承件壳体1的套轮廓以特别合理的方式通过拉深方法制成，为了在支承件壳体1之内构造突出部11，借助于从外部引入的冲压模将凹入部2成型到支承件壳体1中。优选地，为此，凹入部2实施成盆形的、碗形的或球冠形的。此外，为了引导压力介质，支承件壳体1的外壳以与凹入部2间隔开的方式具有多个通孔12，该通孔同样通过压制或冲制而成。
图3以透视图以与图2相反的取向示出了根据本发明的阀座支承件，从而在其俯视图中同样可看出在拉深方法中形成的凸缘形地径向向外部弯曲的凸缘10，该凸缘布置在与倒角6位置相反的套筒端部9处。凸缘10用于紧凑地将阀座支承件固定在电磁阀的未绘出的阀壳体中，该电磁阀的阀关闭元件根据电磁激励或者封闭或者释放阀座体3的阀座4。
为了制造并且形状配合地将阀座体3固定在支承件壳体1中，通过设置在套筒状支承件壳体1处的漏斗形的倒角6将首先液态的塑料输送到支承件壳体1中，为此，借助于可能情况下可伸入支承件壳体1中的塑料注射喷嘴输送塑料。
空心圆柱形的轮廓构成和阀座体3不仅外部地在凹入部2处而且内部地在突出部11处的固定在一个加工过程中通过塑料注塑到突出部11的区域中和凹入部2中而同时实现。
所描述的发明实现了成本适宜地且适用于自动装置地制造阀座支承件，结果是在制造阀座体3的同时使阀座体3绝对可靠地、不可松开地、形状配合地连接在支承件壳体1处。
