Description

修补管道泄漏装置的方法 技术领域
本发明涉及修补管道泄漏的方法，特别是涉及在不干扰管道正常运行情况下对其泄漏进行修补的方法。
背景技术
目前我国在流体容器存储和管道输送领域内，由于突发性因素引起的流体介质泄漏事故时有发生。由于管道输送介质的不断腐蚀、冲刷、温度、振动、季节变化、地质变化、人为等因素的影响，在管道某些部位上不可避免会发生密封失效问题，压力介质随之外泄，如不及时处理，密封失效程度会扩大，泄漏流量会成倍增加，造成企业非计划停产事故以及更严重的事故。
常见的管道泄漏发生在连接部位，连接部位是指为了检修或更换零部件而在压力容器或管道上设置的可拆卸性构建，其中最常见的发生泄漏的部位是法兰。法兰密封是依靠其连接螺栓产生预紧力，通过各种固体垫片或液体垫片达到足够的工作密封比压，阻止被密封流体介质外泄，属于强制密封范畴，其泄漏形式主要有三种：一是由于金属面和密封垫片交界处不能很好吻合发生的“界面泄漏”，和密封垫片的形式以及材料无关；第二是某些垫片材料的纤维和纤维之间有一定缝隙从而使得流体介质在一定条件下通过这些缝隙产生的“渗透泄漏”，一般与流体介质的工作压力成正比，与流体介质的粘性等物理性质也 有关系；第三是安装质量欠佳引起的密封垫片压缩过度或密封比压不足而发生的“破坏泄漏”。
动态密封是指存在泄漏介质压力、温度和流量条件下，采用特殊技术手段进行有效再密封的一门技术，目前工业领域常用的方法有“注剂式带压密封技术”、“带压粘接密封技术”和“带压焊接密封技术”。三种蜜蜂方式各有特点，经济效益显著，安全可靠，消除泄漏快并且具有良好的可拆性，不受泄漏介质物化性质的限制，无需配备专用工具和设备。但是该动态密封需要停止管线工作的情况下才能实施密封操作，影响管线的工作效率。

顶开螺栓55然后被转动去掉线缆51的张力并且线缆张紧装置50被旋转到相邻另一个注射阀23的位置。密封物注射装置60然后被连接到线缆51和绕线42间新接触附近的注射阀23并重复过程。密封物63轮流注入每个注射阀23直到泄漏停止。密封物63然后缓慢注入知道密封物流出道线42和线缆51周围。密封物63允许停留一个短时间段，大约10分钟，然后密封物63被再一次泵入所有注射阀23。
图4是在就要从线圈周围去掉线缆51前密封的视图。线缆张紧感觉50被移走在密封物63等待足够时间在位凝固后。注射阀23已经从注射螺母22和32移走，塞26已经安装来分别关闭孔27和34。密封物63施加来填充法兰13和线42间的边缘。线42一般填充法兰螺栓12上的间隙15并作为增强元件来保持密封物63在位置在受到预料的系统内压力下。密封物63置于线42的外层直到注满在法兰13的外围来提供完整法兰密封光滑、抛光的外表。
密封物根据特定应用选择。低压力下，粒状特氟龙用注射车，如油可以被使用。大多数更高压力的应用必须采用快速凝固的密封物，一般以橡胶或酚类为基。凝固时间一般为5-15分钟。
虽然本发明已经参考特定的说明性实施例进行了描述，但是不会受到这些 实施例的限定而仅仅受到附加权利要求的限定。本领域技术人员应当理解可以在不偏离本发明的保护范围和精神的情况下对本发明的实施例能够进行改动和修改。
