Petroleum chemical pipeline leakage valve automatic closing device
By designing an automatic valve shut-off device for leaking petrochemical pipelines, a dual safety mechanism is implemented that utilizes pressure difference to automatically trigger initial sealing and float flowmeter drive, solving the problems of delayed detection and untimely sealing of oil pipeline leaks, and achieving rapid and reliable leak control.

Abstract
本发明涉及石油输送技术领域，尤其为一种石油化工管道泄漏阀门自动关闭装置，包括：管道，所述管道的顶部设置有关闭组件一；所述关闭组件一包含有与管道相连通的连通管，所述连通管的内腔滑动连接有活塞，所述活塞的右侧固定连接有连接杆。本发明具备自动触发快和双重安全保障的优点，当管道内石油正常流通时压力稳定，一旦发生泄漏，压力骤降形成压力差，这一变化会迅速作用于关闭组件一中的活塞，推动其向右移动，整个过程无需人工干预，利用物理原理自动触发，能够在泄漏发生的瞬间就做出反应，大大缩短了从泄漏发生到开始封堵的时间间隔，有效防止石油大量泄漏，将泄漏范围控制在较小程度，降低经济损失和环境破坏风险。
