Description

阀部件
发明的技术背景
本发明涉及权利要求1前序部分中限定的阀部件,这种阀部件包括主体;至少一个入口和至少一个出口;连接入口和出口的通道;至少一个爆破盘(破裂盘)或等同物,当未破裂时,它关闭从入口至出口的通道;以及活塞部件,它包括刺穿部件或类似物,用于刺穿爆破盘。
与本发明主题相当的装置已由DE 2635076 A说明书中得知。此解决方案的一个缺点是,刺穿部件通过压力作用回复至其原始位置,从而被刺穿作用已由爆破盘上脱落的爆破盘碎片可能局部阻塞通道,形成压力介质流动的障碍。此外,刺穿部件必须完全通过爆破盘,以便在盘中产生要求尺寸的孔。如果由于某一原因刺穿部件未完全执行,它将不产生要求尺寸的孔。
本发明的目的是获得一种全新的解决方案,它可能避免现有技术装置中的缺点。本发明的目的是建造一种可靠的装置,它特别适合在消防中应用。
本发明装置的特征在于,活塞部件设置有压力介质的通道,所述通道从一个第一侧轴向通过活塞部件伸展至一个第二侧,活塞部件设置有第二爆破盘或等同物,在未破裂时,它关闭设置在活塞部件中的通道。
本发明装置的附加特征叙述于权利要求2-7中。
本发明的解决方案具有很多显著的优点。通过活塞的通道确保在设置于活塞部件中的第二爆破盘被刺穿后,活塞将有效地压向第一爆破盘。本发明的解决方案是防泄漏和可靠的。通过应用较小的第二爆破盘,可避免为进行触发动作应用要求大功率的大驱动器。通过应用中间构件,诸如球,获得了第二爆破盘的可靠刺穿,此外还避免了这种情况,即驱动器的活塞保持与第二爆破盘接触,在第二爆破盘中没有产生足够的孔。通过应用阀部件的两级触发,以致在第一级期间,第二爆破盘的刺穿产生压力介质进入活塞腔的流动,从而引起活塞-刺穿器组合强劲地移向第一爆破盘,并刺穿它,获得阀部件的可靠运行,确保从入口至出口的通道可靠地打开。这样,本发明的阀部件优异地适用于灭火系统。
附图概述
下文中,将借助实施例、参考附图对发明加以详细的说明,其中
图1表示按本发明提出的阀部件;而
图2表示按本发明提出的、处于触发状态的阀部件。
发明的详细说明
图1表示按本发明提出的、处于待机状态的阀部件。此装置包括主体11、主体11设置有入口101,它可连接至压力源;和出口102,它可连接至输出管线。设置在入口与出口之间的是爆破盘13(破裂盘),它在未破裂时,关闭从入口101至出口102的通道。装置还包括用于刺穿爆破盘13的装置。装置由汽缸-活塞组合构成,其中,活塞15包括形成于其上的刺穿部件14,刺穿部件14最好形成在活塞杆16的部分上。活塞15布置成可在汽缸空间12内,在第一位置,这时,形成在活塞杆16上的刺穿部件14相对爆破盘13位于入口侧与第二位置之间移动,在第二位置时,刺穿部件相对爆破盘13至少部分伸展至出口侧。
活塞至少设置有一个中心孔17,它通过活塞15伸展,最好从刺穿部件14伸展至活塞15的相对侧。布置在活塞部件中的是第二爆破盘18(破裂盘),它在未破裂时关闭从入口通过中心孔17进入活塞侧上汽缸空间12的通道。入口中的主要压力通常是压力介质的压力,它在待机状态存在于阀中直至第二爆破盘。
形成于刺穿部件的顶部或其附近的至少有一个孔23,它伸展进入中心孔17,从而在爆破盘13被刺穿后形成压力介质的部分通道。此外,装置包括驱动装置,用于驱动活塞-刺穿器组合。图中所示的实施例既设置有手动驱动部件,也设置有自动驱动部件19。驱动部件设计成用于遥控,从而阀部件借助控制信号加以触发。控制信号通常由控制系统通过诸如导线的传输装置21供给。控制信号使驱动部件的活塞向着活塞15和第二爆破盘18移动。放置在活塞15与第二爆破盘之间的是中间构件22,诸如球部件,当驱动部件被触发时,它冲破第二爆破盘18。在触发时,驱动部件的活塞撞击球,由于如此产生的冲力,球冲破第二爆破盘18。驱动部件19最好是信号弹装置,其中,控制电流爆燃驱动装置中的炸药,从而引起驱动部件的活塞强劲地向外推出。驱动部件能连接至控制系统,从而装置能与诸如灭火设备一起作用,触发驱动部件19的冲力从火焰探测器和/或烟雾探测器(未表示)获得。由于驱动部件的触发,第二爆破盘被刺穿后,压力介质得以通过活塞中的中心孔17,及通过形成在爆破盘18中的洞进入活塞空间12,引起活塞向着第一爆破盘13移动(图中所示的实施例中向右),刺穿第一爆破盘13(图2),结果,压力介质能从入口101流至出口102。通过成形于活塞部件中的孔,最好通过成形在活塞杆中的孔,压力介质能进入活塞杆中的中心孔,进一步流至出口102。
在图所示的实施例中,阀部件10还包括专门用于通风目的的第二出口103。此第二出口12能设置有例如阀部件(未表示)或塞子。
这样,阀部件10最好是压力介质系统中的触发阀。
在上述实施例中,活塞部件的活塞杆16密封地倚着汽缸空间的壁而装配,从而压力介质通常只能通过贯穿活塞而设置的通道17而流动。
爆破盘最好设计成能承受高压和高压差。有效压力通常超过30巴,最好超过70巴。压力甚至可高达300巴。爆破盘最好在这样的区域中包括较薄的部分,刺穿部件在触发情况在其上施加作用。
根据本发明提供的阀部件特别适宜和灭火系统一起应用,特别和采用高压水雾的灭火装置一起应用。压力介质可包括气体、液体、或气体和液体的混合物。
对本领域的技术人员来讲,显然本发明不限于上述实施例,而是可在下文提出的权利要求的范围内加以改变。
