本发明涉及一种用于水溶性管道封堵器的推送装置及其管道封堵方法。
背景技术:
目前,输送天然气、石油等易燃易爆物质的管道,在使用一段时间以后,因为管道的腐蚀,需要进行更换和维修,更换和维修时需要进行焊接动火作业。在焊接动火作业时,如果不能有效的对易燃易爆物质进行隔离,就会发生重大的爆炸和燃烧事故。以往对管道进行封堵的方式主要有:(1)黄油封堵法也称黄油墙:这种方法是在需要维修的管道两端推入一定量的黄油,形成一个黄油柱,以起到封堵隔离的作用,缺点是需要操作工人在短时间内完成焊接动火作业,否则黄油会塌落失效,黄油不能够取出残留在管道内会污染管道,不能够承受压力,如压力突破黄油就会造成事故。因为黄油墙不能承受压力,所以在施工前需要使用大量的水和氮气对管道的危险气体进行置换。(2)橡胶球封堵法也称清管球:这种方法是在需要维修的管道两端各放置一个可充气的橡胶隔离球,配合黄油墙一起,起到封堵隔离的作用,操作完成后需要将隔离球取出,缺点是必须能够取出橡胶隔离球,在取出的过程中,需要破坏掉橡胶隔离球,损坏脱落的橡胶残渣会对管道造成污染同时还会对管道上的仪表造成堵塞。因为这种方法同样不能承受压力,所以在施工前需要使用大量的水和氮气对管道的危险气体进行置换。(3)冷冻封堵法:这种方法是在需要更换的管道内部冲满水,使用冷冻设备在管道内冷冻两段冰柱,以此起到封堵的作用,缺点是操作前需要大量的准备工作,需要耗费大量的资源,如果在高温的季节需要很长的冷冻时间,而在寒冷的区域,操作完成后冰柱需要很长时间才可以彻底融化,造成资源上的浪费。

3)封堵部扶正步骤,根据所述封堵部进入管道的形态,决定是否需要进行扶正,如果所述封堵部进入管道的形态保持与管道平行或接近平行时,则无需对所述封堵部进行扶正;如果所述封堵部进入管道的形态与管道存在较大偏角时,则由所述扶正装置对所述封堵部进行扶 正;
4)封堵部安装步骤,由所述推送装置将所述封堵部由管道开口部向与所述水溶性密封胶位置推送,并对所述封堵部施加一定的压力;
5)承压部安装步骤,将所述承压部推送至与所述封堵部相临近的位置,并对承压部施加一定压力,使其与封堵部紧密连接。
步骤4)中对所述封堵部施加一定的压力,应使所述水溶性密封胶进入所述封堵部与管道内壁邻接部的侧面。
实施例2
如图1-4,图11所示,本发明涉及的多段水溶管道封堵器,包括一由水溶材料制成的封堵部、密封胶、圆柱形承压部组成。管道内压力首先推动封堵部,封堵部受力后挤压密封胶,密封胶受挤压填满承压部中间的圆台体状孔,然后流到承压部外侧的环形凹槽的容纳部,形成多个密封圈。借此提高产品的密封性能。
封堵部与管道内壁接触的侧面,设置有用于与管道粘接的胶带。
承压部外侧设有与推入方向形成倒刺形状的柔性或弹性外延,可以推入,管道内压力出现,向后推动承压部时,承压部的边缘逆向于管壁,增加了摩擦力。承压性就得到了提高。承压部由多个承压部分段配件组合装配而成,每间隔几个倒刺柔性或弹性外延结构会有一个与内部相通的环形凹槽。承压部内部形成中空,一端开口另一端封闭。

在封堵部与管道内壁接触的外延,有多个柔性外延,可以收缩变形。封堵部圆台体状结构上设有防转凸起,与承压部内部的防转凹槽配合,起到防止转动的目的。封堵部设有连接杆,连接杆上面设有螺纹。
封堵部和承压部的中间填充密封胶,通过连接杆上的螺纹拉紧,挤压密封胶,密封胶受力后填充承压部外延和管壁的细小缝隙,以及两个椎体的缝隙,达到完全密封的目的。彻底拉紧后封堵部和承压部中间还留有一定间距,确保密封胶留有充足的余量空间。
所述封堵部的连接部是圆台体状,在圆台体状面的前面设有连接杆,连接杆上设有螺纹。
所述承压部与管道内壁接触的外延,有多个柔性外延,可以收缩变形。封堵部圆台体状结构上设有防转凸起,与承压部内部的凹槽配合,起到防止转动的目的。

进一步的改进,可以是:所述锁胶密封圈形状相当于两个内径相同、外径不同的圆环柱的组合,其横截面以轴心为界的顶端或下端呈台阶状,与管壁接触的侧面设有胶带,可以粘贴在管道内壁上。
