Description

电缆插入插口
本发明是关于在进行无损检测时把带有探测器的电缆插入到各种热交换管的操纵装置的插口。
在热电厂和核电厂进行热交换管的无损检测时通常采用超声波探伤法或涡电流检验法,在这两种方法中,藉助于加压水和压缩空气,一根带有浮体和其顶端带有探测器的电缆从热交换管各自的端头被插入热交换管,以完成检测。
图6显示了一根带有浮体并已插进热交换管的电缆准备通过操纵装置的插口从中撤出的状态,操纵装置的插口在回压的作用下被压附于热交换管的一个管端部分(或被压附在基板上)。当然,一个类似于上述插口的插口被压附于相对于图6所示管端部分的零一个管端部分以向该处施加回压。参照图6,一种普通结构被解释如下,图6中,热交换管1被插入基板2的沉孔内后,它们被密封焊接,如图中阿拉伯数字3所示。操纵装置的插口部分被分成球形的内球面体4和外球面体5,一个插口盖6和盖螺钉7把这些球面体连结在一起,一个橡胶密封垫8被装在内球面体的平面上以防止加压水和压缩空气的泄漏。在电缆9上附着一个浮体9a来产生轴向压力,这个力对于输送(插入或撤出)电缆是很有效的。简而言之,普通插口的特征是被分成两个球面体从而形成一个球面座。用上述的结构,即使当由于操纵装置的弯曲或类似的情况使插口的中心离开原来的位置时,也可容易地把插口插入管端部分(孔内)。
然而,图6所示的球面座往往在球面座部分(插口的内表面)造成一个台阶。因此,浮体9在输送(插入和撤出)电缆过程中有时被卡住,使电缆输送不到位。
本发明的目的就是提供一种在其内表面不产生台阶的插口,因而可平稳地输送电缆和它的浮体。
为达到上述目的,本发明提供了一种带球面座的电缆插入插口,斑面座是由两个分开的球面体,即内球面体和外球面体构成,其特征为在内球面体和外球面体的内部圆周表面有一个凹腔,当内球面体的轴心线与外球面体的轴心线重合时,该凹腔的轴向断面大致呈矩形,其横向断面大致呈圆形,凹腔内浮动地放着或是一个筒状零件或是一个笼状零件,它们的两端部分都有一个凸缘,并且其内部直径与内、外球面体的内部原始设计直径大致相等。
从上述结构明显看出,本发明的插口并未失去球面座的功能,这是因为在根据本发明放置的筒状零件或笼状零件与球面座的内圆周面之间留有一个间隙。而且,由于筒状零件或笼状零件的内部直径被加工成与内球面体和外球面体的内部直径相等,在插口的内表面就不会产生台阶,所以可平稳地输送电缆和浮体。
图1是解释本发明的电缆插入插口处于工作状态时的轴向断面侧视图。
图2和图3显示了放在本发明电缆插入插口内凹腔中的筒状零件,其中图2是沿图3箭头Ⅱ-Ⅱ所示方向的正视图,图3是沿图2箭头Ⅲ-Ⅲ所示方向的轴向剖面侧视图;
图4和图5显示了放在本发明电缆插入插口内凹腔中的笼状零件,其中图4是沿图5箭头Ⅳ-Ⅳ所示方向的正视图,图5是沿图4箭头Ⅴ-Ⅴ所示方向的轴向剖面侧视图;
图6是现有技术中电缆插入插口的轴向剖面侧视图。
参照图1到图5,根据本发明的电缆插入插口的实施例描述如下:
在图1中,与图6中阿拉伯数字一致的零件具有与其相同的功能,因此这里不再描述它们。
根据本发明,在组合而成的电缆插入插口的球面座部分(即由内球面体14的内圆周面和外球面体15构成)有一个凹腔V,凹腔V是由切口14a和切口15a组成,当内球面体14和外球面体15的轴心线重合时,在轴向剖面上凹腔V是矩形,在横向剖面上是圆形。在这个凹腔V中浮动地安放着一个筒状零件,其两端部分都有一个凸缘16a,凸缘16a的外部直径比凹腔V的内部直径小一点,筒状零件的内部直径与内球面体14和外球面体15的内部原始设计直径大致相等。因为筒状零件16上除了凸缘部分16a外,其外部圆周面即它的圆柱段16b在剖面上是凹形的,并且在轴向剖面上,在它和外球面体的切口15a之间造成了一个V型空间,所以外球面体16的上端部分可以在插口的球面座内自由摆动。而且,由于筒状零件的内部直径被加工成与内球面体14和外球面体15的内部原始设计直径大致相等,所以在插口的内部圆周面上不会造成台阶,这样,电缆9和浮体9a就可被平稳地输送。
此外,如果整个筒状零件16或筒状零件16的内表面是由象聚四氟乙烯之类的含氟树脂制成,因为这种材料的摩擦阻力很小,电缆9和浮体9a的输送就会更平稳。
图4和图5显示了放置于本发明电缆插入插口内凹腔中的笼状零件17。
在图4和图5中,阿拉伯数字17a表示二个安装于上、下端部分的环,它们等于图2和图3所示的筒状零件16上的凸缘16a。阿拉伯数字17b表示钢丝,它们的上、下端插入上、下环17a上沿圆周方向等距分布的孔中,并用焊锡固定,这些钢丝等于图2和图3所示的筒状零件16的圆柱段16b。虽然笼状零件17是由环17a和钢丝17b构成,其功能和效果与筒状零件16一样。
如上所述,这种根据本发明的电缆插入插口有一个由两个分开的内球面体和外球面体构成的球面座,其特征为在内、外球面体的内圆周面上有一个凹腔,当内球面体的轴心线与外球面体的轴心线重合时,这个凹腔在轴向剖面上呈矩形在横向剖面上呈圆形,在凹腔内浮动地放置着或是一个筒状零件或是一个笼状零件,它们的两端都带有一个凸缘,它们的内部直径与内球面体和外球面体的内部原始设计直径大致相等;这样,这个插口,或外球面体的上端部分就可在球面座内自由摆动,并且由于在插口的内部圆周面上不会产生台阶,所以用来进行无损检测的带有浮体的电缆就可被容易地插入和撤回。
