一种燃气管道封堵装置
本技术属于燃气管道
,具体涉及一种燃气管道用封堵装置。
技术介绍
随着燃气事业的发展和管道设备数量的增加,以及原有管道及设备的腐蚀老化,日常维抢修及技改项目逐渐增加。现有的作业方式由于受到作业环境及设备本身的限制,作业耗时长,影响范围大,人力物力消耗多,还会造成一定的资源浪费和环境污染,对泄漏点或者存在隐患的部位一旦错过了最佳处置时间,还将影响和威胁公共利益和公共安全,影响安全稳定供气。目前国内外对带气燃气管道进行带压封堵作业,主要采用在管道上焊接四通管件后,对管道进行整管切断,再利用配套膨胀桶膨胀后封闭管线切断面的原理进行封堵。然而现有技术的采用整管切断的方案破坏了管网的完整性,造成管道强度降低,并且四通管件体积大,增加了作业难度和作业成本,封堵效果也并不理想。
