Description
技术领域
本发明的主题是一种阀,该阀带有驱动器、与驱动器相连接的推杆以及两个关闭体,所述两个关闭体与推杆相连接并能被推杆移动为,使得所述两个关闭体能够运动到贴靠密封座或能以离开密封座的方式运动。
背景技术
这种阀用于打开和关闭机动车辆中的排气管路,因此是已知的。阀关闭管路的密封性对于此类阀的功能很重要。特别是对于气体,低泄漏率的实现往往带来高成本。阀座和关闭体的密封面必须互相紧密贴靠。就其粗糙度和公差而言,它们的表面必须具有较高的表面质量。同时,密封面和阀座必须满足很小的形状公差。最后,由推杆和驱动器引起的阀体运动必须满足对位置公差的高要求。为此,阀体套在推杆上。然后当推杆到达安装位置时将其插入壳体,可以将关闭体固定到推杆上。借助于焊接来固定。位于壳体深处的关闭体使得焊接工具的使用更加困难,这使得焊接过程非常复杂。另外已知将关闭体设计成具有两个密封表面,以便再次补偿由于复杂的焊接过程而不可避免的制造公差。此处的缺点是,为补偿与制造相关的公差所带来的额外的密封表面成本。
发明内容
因此,本发明的目的是,提出一种可低成本制造的阀,该阀具有尽可能低的泄漏率,并且可以长期稳定地工作。本发明的另一个目的是,提供一种制造这种阀的方法。
该目的通过如下的阀来实现:关闭体固定地布置在套筒上,套筒套置在推杆上并与其固定连接。
通过提供能被套置在推杆上并且其上固定有关闭体的套筒,能够形成如下的组件:该组件能够在阀壳体的外部就已经被预先组装好,然后被推入壳体,更确切地说被套置在推杆上。由于根据本发明一些固定过程可以在壳体的外部进行,由于更好的可达性,它们可以明显更快地进行,因此更容易进行。同时,这减少了需要在阀壳体中执行的固定过程的数量。从而仅需要执行在阀壳体中易于建立的固定过程,这进一步显著降低了阀的制造成本。另外由于根据本发明的结构和易于建立的固定过程,因此可以保持低公差,并确保特别低的泄漏率。
根据一个有利的设计方案,通过将套筒焊接到推杆上来实现套筒与推杆的特别可靠和长期稳定的连接。
在另一个有利的设计方案中,套筒和推杆被压接在一起/彼此压配合。这种连接的特点是特别低成本。
在另一个有利的设计方案中,关闭体可以通过焊接在套筒上来牢固地与套筒连接。
本发明的第二个目的是通过以下方式实现的:将至少一个关闭体焊接到套筒上,将套筒套置到推杆上直到关闭体贴靠在密封座上,然后,使另一关闭体与套筒焊接连接和/或使套筒与推杆相连接。
根据本发明的方法允许将至少一个关闭体固定到套筒,以便制造预组装组件。
由于焊接点可被自由地接近,所以能快速可靠地制造预组装组件。避免了由于难以进入阀壳体而导致的困难的焊接连接。然后,将预组装的组件套置在推杆上,直到至少一个关闭体与其密封座贴靠。然后,将另一个关闭体推到分配给它的密封座上,并固定在套筒上,和/或将套筒固定连接到推杆上。
在另一设计方案中,两个关闭体在被推到推杆上之前被焊接到套筒上以形成预组装组件。由于焊接点可被自由地接近,这种预组装组件的突出之处还在于其特别容易的可制造性。密封座的间距公差可以通过考虑运行过程中的热条件来补偿,从而通过这种预组装组件也可以制造出泄漏率非常低的阀。
在一种有利的设计方案中,套筒被焊接到推杆上,由此产生牢固且长期稳定的连接。
根据另一个有利的设计方案,可以通过将两个部分压接在一起来实现套筒和推杆的连接。
附图说明
根据实施例详述本发明。在此:
图1示出根据现有技术的阀,
图2示出根据本发明的阀的阀室。
具体实施方式
图1示出了根据一个实施例的、用于打开和关闭排气管的阀100。图1中的阀100具有壳体1,在壳体1中布置有电机2。借助于传动装置3,电机2的旋转运动被转换成推杆4的直线运动。在变速器3上布置有传感器5,该传感器与固定在推杆4上的磁体协同作用。推杆4从传动室6延伸到阀室7中,其中推杆4在两个位置8处得到支承。阀室7由三个依次布置的子室7a、7b、7c组成,这些子室分别通过密封座9彼此分开。两个关闭体10a、10b布置在推杆4上,从而在推杆4沿着推杆4的纵向轴线移动的情况下,使得所述关闭体能够贴靠在相应的密封座9上并且密封开口11,或能够远离密封座9并且打开开口11,使得气体可以从一个阀室7流到另一个阀室中。
在图2中,套筒12布置在推杆4上,该套筒带有两个盘形的关闭体10a、10b。关闭体10a、10b经由两个焊接连接部15a、15b焊接到套筒12上,从而它们在阀的关闭状态下贴靠相应的密封座9,由此它们关闭开口11,使得气体不能从一个阀室7经由其他阀室7流出。
在阀的关闭状态下,泄漏率几乎为零。这通过将关闭体10a套置在套筒12上,并且借助于焊接连接部15a焊接到套筒上而实现。这是在阀外部完成的。套筒12和关闭体10a形成预组装组件。然后通过将套筒12朝向传动装置3的方向推到推杆4上,并将其接合到推杆上来将预组装组件引入壳体1中。为此,穿过开口13引入预组装组件。套筒12被套置在推杆4上,直到关闭体10a贴靠其密封座9。然后,另一关闭体10b在套筒12上被定位成,使得其也贴靠其密封座9。在该位置,关闭体10b被焊接到套筒12上。套筒12还通过焊接连接部16焊接到推杆4。焊接连接部15b、16是相对容易接近的,由此可以以简单的方式执行焊接过程。然后用盖件14封闭开口13从而界定出腔室7c。
