Description
技术领域
本发明涉及一种用于控制气态介质、尤其氢气的配量阀和喷射泵单元,所述配量阀和喷射泵单元例如应用在具有燃料电池驱动装置的车辆中。
背景技术
DE 10 2010 043 618 A1说明一种用于控制气态介质、尤其氢气的配量阀,其中,所述配量阀包括阀壳体、喷射器单元、促动器和关闭元件。在阀壳体中构造有贯通开口,该贯通开口可以通过关闭元件在阀座处被释放或封闭。喷射器单元包括流入区域,处于压力下的第一气态介质被输送给该流入区域,所述喷射器单元还包括抽吸区域和混合管区域,在该抽吸区域上作用有第二介质,第一气态介质和第二气态介质的混合物从该混合管区域中流出。贯通开口布置在喷射器单元的流入区域和抽吸区域之间。
配量阀的特点如下:在使用这些配量阀时,在燃料电池的阳极路径中仅出现小的压力波动,并且可以确保安静运行。在配量阀的正常运行区域中,频繁出现打开和关闭过程。为了优化燃料电池的阳极路径中的扫气过程或为了实现喷射泵在燃料电池组件中的优化运行,也可以期望附加的切换过程。然而,尤其在如DE 10 2010 043 618 A1所示的组件中,配量阀的频繁打开和关闭会导致阀座处的磨损,从而导致阀座处的密封性变差。
通过对由配量阀和喷射泵构成的组合的改进设计可以实现磨损减少并从而实现配量阀的优化功能方式。
发明内容
与此相对,本发明的用于控制气态介质、尤其氢气的配量阀和喷射泵单元具有以下优点:通过将配量阀优化地集成到喷射泵单元中,改进了阀座处的公差并且由此提高阀座处的密封性。
为此,用于控制气态介质、尤其氢气的配量阀具有阀壳体,在该阀壳体中构造有内室。在所述内室中布置有能进行行程运动的关闭元件,该关闭元件与阀座共同作用,用于打开或关闭至少一个第一贯穿通道。此外,配量阀具有喷嘴,所述至少一个贯穿通道构造在该喷嘴中,其中,该贯穿通道具有圆柱形区段。
此外,喷射泵单元包括本发明的配量阀、喷射泵壳体、混合管区域和抽吸区域。喷射泵壳体包括配量阀的阀壳体并包括泵壳体。有利地,在泵壳体中构造有配量阀的输入通道。贯通孔至少区段地构造为锥形,并且喷嘴和阀座被接收在贯通孔中。
通过将喷嘴集成到配量阀中,使得气态介质朝着阀座的流动能够被直接引导到喷射泵单元中。由此,可以实现配量阀和喷射泵单元的优化设计。此外,在气态介质的流动必须走过配量阀与喷射泵单元之间的、例如经由管的较长路程时所产生的压力损失被最小化。此外,通过将喷嘴集成到配量阀中,可以改进阀座处的可能公差,尤其可以改进阀座处的密封性,并且可以实现阀座直接构造在喷嘴上。本发明的配量阀到喷射泵单元中的集成证明不仅在结构上是有利的,而且也有助于其优化的功能方式。喷嘴这样布置在喷射泵单元的贯通孔中,使得围绕该喷嘴产生来自抽吸通道的气态介质和来自配量阀的气态介质的优化流动。
在第一有利扩展方案中,喷嘴附接到阀壳体上并且与该阀壳体固定连接。有利地,喷嘴被接收在阀壳体中。由此,喷嘴可以以在结构上简单的方式布置在配量阀中。
在本发明的另一构型中有利地设置,喷嘴具有纵轴线,并且贯穿通道构造为喷嘴中的中心孔。由此确保来自配量阀的气态介质优化地流动到喷射泵单元的贯通孔中。
在一个有利的扩展方案中,喷嘴包括环边和榫部。在此,所述榫部有利地构造为锥形。环边能够以简单的结构方式实现喷嘴到配量阀中的优化的固定集成,其中,喷嘴通过榫部优化地嵌接到喷射泵单元中。榫部的锥形构造能够实现气态介质在喷射泵单元的贯通孔中的优化流动。
在本发明的另一构型中有利地设置,至少一个贯穿通道的高度小于100mm,优选小于30mm。阀座与喷嘴的流出开口之间的间距应设计得尽可能短,以便使在贯穿通道中产生的压力损失最小化。
在另一有利的构型中设置,在至少一个贯穿通道的圆柱形区段上衔接有锥形区段。有利地,喷嘴在喷嘴的流入侧端部处具有直径d,并且在流出开口处具有另一直径D,其中,D大于d。由此,喷嘴在流出开口处具有扩散区域,由此实现将来自贯穿通道的气态介质优化地带入到喷射泵单元的贯通孔中。
在本发明的另一构型中有利地设置,阀座构造在喷嘴的流入侧端部处。有利地,喷嘴具有密封棱边,在该密封棱边处,阀座构造为平座。由此可以以简单的结构方式实现喷嘴到配量阀中的集成,其中,同时确保阀座的密封性和功能方式。
在本发明的另一构型中,在阀座与关闭元件之间布置有弹性密封元件。由此可以确保配量阀的高密封性。
所述配量阀优选在燃料电池组件中适用于控制向燃料电池的阳极区域的氢气输入。优点是,阳极路径中的压力波动小并且运行安静。
附图说明
在附图中示出本发明的用于控制向燃料电池的气体输入、尤其氢气的配量阀和喷射泵单元的实施例。附图:
图1以纵剖面图示出具有喷嘴的本发明配量阀的实施例,
图2以纵剖面图示出具有在图1中示出的配量阀的本发明喷射泵单元的实施例。
具有相同功能的构件用相同的附图标记表示。
具体实施方式
图1以纵剖面图示出本发明的配量阀1的实施例。配量阀1具有阀壳体2,该阀壳体具有内室3。在内室3中布置有电磁体39,其中,电磁体39包括电磁线圈16、内极12和外极14。此外,在内室3中布置有可进行行程运动的电磁衔铁装置38。电磁衔铁装置38包括电磁衔铁6和连接元件8,其中,连接元件8被接收在电磁衔铁6的槽口29中并因此例如通过焊缝或者通过压紧与电磁衔铁6固定连接。电磁衔铁6构造为***式衔铁并且被接收在内极12中。连接元件8在内极12的槽口中在第一导向区段31处并且在阀壳体2的槽口中在第二导向区段33处被接收并被导向。
在阀壳体2上布置有喷嘴11。喷嘴11包括环边47和榫部48。喷嘴11的环边47与阀壳体2例如通过压紧来固定连接。喷嘴11的榫部48构造为锥形,其中,榫部48向环边47的方向变宽。
喷嘴11具有纵轴线40,其中,该纵轴线与配量阀1的纵轴线相同。在此,在喷嘴11中构造有作为中心孔的贯穿通道25。喷嘴11中的贯穿通道25具有圆柱形区段50,在该圆柱形区段上衔接有锥形区段51。贯穿通道25具有小于100mm、优选小于30mm的高度h。在喷嘴11的流入侧端部13处,喷嘴11的圆柱形区段50具有直径d。在喷嘴11的流出开口18处,该喷嘴具有另一直径D,其中,D大于d。喷嘴11在流出开口18处具有扩散部。
阀壳体2和内极12限界弹簧室34,该弹簧室形成内室3的一部分。在弹簧室34中布置有关闭弹簧24,该关闭弹簧支撑在阀壳体2和连接元件8的盘形端部19之间。关闭弹簧24对电磁衔铁装置38施加以向喷嘴11方向的力。内室3还包括电磁衔铁室36,该电磁衔铁室由阀壳体2、内极12和套筒元件20限界。套筒元件20与内极12和阀壳体2通过焊缝7固定连接,使得套筒元件20用作间隔件并且相对于电磁线圈16密封电磁衔铁室36,使得没有气态介质(在此是氢气)可以流经电磁线圈16。
在与连接元件8的盘形端部19相对置的端部上布置有关闭元件10。该关闭元件10例如通过焊缝或通过压紧与连接元件8固定连接。此外,构造为片形的弹性密封元件9附接到关闭元件10上并且与该关闭元件固定连接。
在喷嘴11的流入侧端部13上构造有作为平座的阀座37。在此,阀座37构造在喷嘴11的密封棱边15上。阀座37与关闭元件10和弹性密封元件9共同作用,用于打开或关闭贯穿通道25。在配量阀1的关闭位态中,如在图1中示出那样,弹性密封元件9贴靠在喷嘴11的密封棱边15上并因此贴靠在阀座37上。
在电磁衔铁室36中布置有电磁衔铁6。弹簧室34和电磁衔铁室36通过第一连接通道32彼此流体连接。
此外,内室3包括控制室27,带有弹性密封元件9的关闭元件10布置在该控制室中。控制室27通过第二连接通道30与电磁衔铁室36连接。在阀壳体2中,垂直于配量阀1的纵轴线40地构造有两个输入通道28,由此,可以对内室3充注以气态介质,例如氢气。所述输入通道28通到控制室27中。
配量阀1的功能方式:
在电磁线圈16未通电的情况下,关闭元件10通过关闭弹簧24被压到阀座37上,使得控制室27与贯穿通道25之间的连接中断并且没有气体流量发生。
如果对电磁线圈16通电,那么产生作用到电磁衔铁6上的磁力,该磁力与关闭弹簧24的关闭力方向相反。该磁力通过连接元件8被传递到关闭元件10上,使得关闭弹簧24的弹簧力被克服并且关闭元件10从阀座37抬起。从控制室27到贯穿通道25中的气体流量被释放。
因为配量阀1在此构造为比例阀,所以关闭元件10的行程可以通过电磁线圈16上的电流强度的高低来调整。电磁线圈16上的电流强度越高,关闭元件10的行程则越大并且配量阀1中的气体流量也越高,因为关闭弹簧24的力与行程有关。如果电磁线圈16上的电流强度减小,那么关闭元件10的行程也减小,因此气体流量被节流。
如果在电磁线圈16上的电流中断,那么作用到电磁衔铁6上的磁力减小,使得作用到关闭元件10上的力借助连接元件8被减小。关闭元件10向贯穿通道25的方向运动并且借助弹性密封元件9在阀座37处密封。配量阀1中的气体流量中断。
本发明的配量阀1例如可以使用在燃料电池组件中。借助于配量阀1,可以将来自罐中的氢气输送给燃料电池的阳极区域。从而,视配量阀1的电磁线圈16上的电流强度的高低(通过该电流强度的高低来操纵关闭元件10的行程)而定地这样改变贯穿通道25处的流动横截面,使得连续地进行对输送给燃料电池的气体流动的、符合需求的调整。
因此,用于控制气态介质的配量阀1具有如下优点:在此,在同时调节阳极压力的情况下,借助于电子控制地匹配贯穿通道25的流动横截面能够显著更精确地进行第一气态介质的输送和氢气到燃料电池的阳极区域中的配量。由此,明显改进了所附接的燃料电池的运行安全性和耐久性,因为总是以超化学计量的份额来输送氢气。此外,也可以防止后续损失,例如防止布置在下游的催化器损坏。
图2以纵剖面图示出具有本发明配量阀1的喷射泵单元46。喷射泵单元46具有喷射泵壳体41,该喷射泵壳体包括配量阀1的阀壳体2和泵壳体49。
在泵壳体49中构造有配量阀1的贯通孔42、抽吸通道43和输入通道28。在贯通孔42中构造有抽吸区域44和混合管区域52。配量阀1与纵轴线40同轴地部分地被接收在贯通孔42中,该纵轴线也相应于喷射泵单元46的纵轴线。喷嘴11和阀座37布置在贯通孔42中。喷嘴11这样布置,使得该喷嘴在轴向上布置在混合管区域52前面。此外,喷嘴11将抽吸区域44与混合管区域52隔离开。
贯通孔42至少区段地构造为锥形,使得在流出区域45处,气态介质的较大流量横截面穿过贯通孔42流动。
贯通孔42在此相对于纵轴线40轴向地构造。例如也可能的是,贯通孔42相对于纵轴线40径向地构造。
喷射泵单元46的功能方式:
在配量阀1的阀座37打开或部分打开的情况下,来自罐的气态介质,例如氢气通过阀座37从配量阀1的输入通道28流动到喷嘴11中的贯穿通道25中。该氢气在从喷嘴11中流出并流入到贯通孔42中之后在抽吸区域44中撞到气态介质、同样是氢气,并且通过抽吸通道43被引回到喷射泵单元46中,所述氢气已被输送给燃料电池,然而还未被使用。在混合管区域52中,由于气态介质的脉冲交换,质量流从抽吸区域44中被抽吸出并且向流出区域46的方向并因此向燃料电池的阳极区域的方向被输送。视贯通孔42的几何形状和配量阀1和从而喷嘴11的装入角度而定,可以对输送给燃料电池的气体流动进行符合需求的调整。
