Description

用于将阻塞装置引入到管道内的设备
技术领域
本发明涉及一种根据权利要求1的前序部分所述的用于将阻塞装置引入到管道内的设备。
背景技术
用于关闭输送流体的管道的阻塞装置存在多种实施形式。它们可以手动或自动地操纵。为了自动操纵,占据关闭位置取决于超过预定的参数,例如一个不允许的流量增加或一个不允许的温度升高。通常阻塞装置在管道铺设期间用在管道间的规定的位置。
在WO 92/01184A1中作为一个实例描述了一个用于气体管路的安全关闭装置。如在图1中明显示出的那样,壳体由一个管件组成,管件在两个端部设有螺纹。安全关闭装置借助螺纹在气体管路铺设期间中间拧在规定位置。
在管道之间使用连接元件也是可能的,阻塞装置插入到管道内。这样从实用新型DE 9319910U1已知,阻塞装置插入到一个所谓的电焊套筒中,正如它用于连接由塑料制成的管道那样。
在这种解决方案中的缺点是,事后安装到已经铺设的管道内只有以很大的消耗通过暴露和拆开管道才是可能的。在已经铺设在地下的管道中,这种消耗不再是可接受的。
在DE 10324041B4中描述了一种用于输送气体的管道的阻塞装置,一种所谓的气体流量控制器。这种气体流量控制器可以在一条气体管路中安放在一个对于安全功能来说最佳的位置并且在那里定位。为此气体流量控制器固定在一个推件上,该推件本身与一个锁紧环可拧紧。锁紧环在其远离膨胀环那侧具有一些弹簧弹性的元件,这些元件防止锁紧环在管道内扭转。此外在推件的圆周上还设置一个膨胀环,该膨胀环通过拧紧推件与锁紧环而变形,同时出现直径增加。
除了复杂的结构和各零件制造非常昂贵外,这种解决方案具有如下缺点,已在插入管道开始密封件就出现预挤压。这样的结果是,除了在到期望的安装地点的装配距离期间增加的能量消耗外,首先导致作用到密封件上的严重磨损效应,特别在干燥的内壁情况下。通过在压入时出现的反转力和在安装地点连续运行作用,弹簧弹性的功能元件还在管道内壁上在整个装配距离上附加产生一种切口应力集中效应。
发明内容
本发明基于的问题是,实现一种用于将一个阻塞装置引入到一条管道内的设备,该设备具有尽可能简单的结构并且适用于在已经铺设的管道中进行改进。该设备可以在管道内安放在一个对于该功能来说最佳的位置并且在那里定位。在此该设备直到安装地点的输送应该以尽可能低的能量消耗进行,并且特别是密封件无接触继而无磨损地运动。仍然确保在该设备和管道的内径之间的内部密封。
根据本发明,通过这样的方式解决所述问题,即,用于将一个阻塞装置引入到一条管道内的设备包括一个管形壳体,在该壳体的内部设置一个阻塞装置,并且壳体如此构成,以致一个缩进的、逆着插入方向锥形逐渐变细的区域紧接壳体的沿插入方向看前面的其外径比管道的内径略小的圆柱区域,该锥形逐渐变细的区域通过一个止挡凸缘界定,一个用于本身已知的驱动部件的连接件的连接轮廓紧接所述止挡凸缘。一个由一种可膨胀的材料制成的滑块沿轴向可移动地设置在锥形的逐渐变细的区域上,滑块的直径在贴靠止挡凸缘状态下比管道的内径略小,并且滑块具有一个环绕的槽,一个弹性的锁紧环支承在该槽内。
与此同时发现一种解决方案,利用该解决方案可以解决上述问题。
本发明进一步有利的设计由其它的权利要求给出。例如通过将壳体与阻塞装置一体连接的方式可以简化结构。在此阻塞装置例如包括一个用于自动阻塞一些气体管路的气体流量控制器。
此外证明有利的是,锁紧环的直径沿插入方向逐渐变细,以便改善该装置到管道内的插入和在管道内的插入运动。
另一种有利的设计是,锥形区域在其两个端部区域内分别具有一个附加的圆柱区域,以避免在两个最终位置出现轴向作用的分力。
为了再进一步提高在设备和管道的内径之间的内部密封的可靠性,滑块可以具有一个第二槽,一个O形环支承在该第二槽内。
在通过一个O形环保证内部密封时,通过在滑块上存在的具有一个或多个轴向开口的径向环岸的方式,减小设备插入时的力是可能的。
附图说明
下面借助一个实施例详细描述本发明。其中:
图1一个根据本发明设备在插入位置的局部剖视图,
图2图1的根据本发明的设备在最终位置的视图。
具体实施方式
在图1中描述了一个根据本发明的用于将阻塞装置引入到管道内的设备的示例性实施形式,在管道2中已经插入状态下在插入运动至安装地点的时刻。为了说明,插入方向通过在图中的一个方向箭头表示。安装可以在例如由聚乙烯材料制成的柔性可膨胀管中进行,但也可以在例如由钢材料制成的刚性管中位置任意地进行。借助一个本身已知的驱动部件,如一个由于本领域技术人员已知而未示出的挠性轴,在管道2中将该设备一直输送到规定的安装地点。
本发明的设备具有一个管形壳体1,其外径这样确定,以致该壳体可插入到管道2中。为了使插入到管道2中得以简化,具有较大直径的圆柱区域3沿插入方向在开始侧设有一个插入斜面4。
在壳体1的内部在一个镗孔5中气密地压入一个阻塞装置6,在这种情况下是一个气体流量控制器。一个气体流量控制器的结构和作用方式对本领域技术人员来说是已知的。所以在本实施例中没有对细节进行更详细地描述和解释。
沿插入方向看,壳体1在端侧具有一个连接轮廓,本在实施例中是连接螺纹7,用于与一个之前已经提及的驱动部件的连接件连接。可理解的是,根据连接件也可以使用一种卡口式连接或其它连接。
紧接着圆柱区域3,壳体1的外部轮廓具有一个缩进区域8,该缩进区域在第一圆柱部分9之后过渡到一个锥形逐渐变细的区域10,而后再终止于一个第二圆柱部分11。
在一个终止缩进区域8的止挡凸缘12上在初始状态下支撑一个在第二圆柱部分11上轴向可移动支承的滑块13,该滑块由一种能膨胀的材料例如聚乙烯构成。止挡凸缘12在其远离缩进区域8那侧设有一个斜面18,以便能够将滑块13更容易地安装到壳体1上。
滑块13在其外面上设置有两个槽。而其中一个槽用于容纳一个用于保证气密性的O形环14,在另一个槽内弹性地支承一个开口的金属的锁紧环15,其直径在弹起状态下比管道2的内径大并且沿插入方向逐渐变细。在此O形环14和锁紧环15的位置和参数通过这样的方式确定,即在图2中所示并且在下文中详细解释的安装状态,通过锁紧环15,对O形环14的密封效果没有不利的影响。在滑块13的外面上通过两个引入的槽形成的一些环绕的环岸16还分别设有四个均匀地分布在圆周上的开口17。
在本实施例中描述的用于将一个阻塞装置引入到一条管道内的设备的安装和工作原理如下:
如前所述,在图1的实施例中所示的设备经由连接件与一个未示出的挠性轴连接。然后借助挠性轴将该设备引入到管道2内。在此滑块13处于第二圆柱区域11上。滑块13的直径以及安装的O形环14的外径比管道2的内径小,而弹性的锁紧环15与该内径匹配并且沿壁滑动。插入运动继续进行直到达到规定的安装地点。
在达到安装地点之后,借助挠性轴逆着插入方向施加一个拉力,用于设备的定位。在图2中示出图1中所示的设备在管道2内的安装地点定位的时刻。
根据管道2的材料,通过施加的拉力,将锁紧环15压到壁上或压到壁内,从而位置固定地保持滑块13。锥形区域10滑动到滑块13下并且将滑块引导到一个扩张部,直到滑块13处于第一圆柱部分9上。通过这个扩张部,还将用于所需密封的O形环14压到内壁上。在此分布在环岸16的圆周上的开口17用于在扩张时减少能量消耗。
随后从设备拆下连接件,这在这种情况下通过旋转运动实现,并且向外拔出带有连接件的挠性轴。于是到管道2内的安装结束。
