Rapid sealing plate type tank root safety emergency device

Abstract

The invention discloses a rapid sealing plate type tank root safety emergency device. The rapid sealing plate type tank root safety emergency device comprises a device body. A device cover part is arranged at the upper portion of the device body through an axial positioning part and a sealing part. A supporting frame is arranged above the device cover part. The device body is internally provided with a sealing plate assembly reset component, a sealing plate assembly and a mechanical lock and movable steel plate combined component, all of which are coaxially arranged in the device body. A medium channel is arranged at the lower portion of the device body. The rapid sealing plate type tank root safety emergency device has the beneficial effects that the sudden leakage event possibly happening in the pipeline transportation process can be rapidly avoided through a tank root arranged on a pipeline or a hazardous chemical substance storage tank, the purpose can be achieved only through gravitational potential energy and command signals provided by batteries, and commercial power and power of other forms are not needed; the rapid sealing plate type tank root safety emergency device is arranged on a long-distance pipeline branch transportation section pipe net joint and is in an emergency standby state, leakage of hazardous chemical substance media can be stopped in a full-automationmanner at dangerous time, accident enlarging and environment polluting are prevented, and accordingly life harm and property losses are reduced.

Description

technical field [0001] The invention relates to a pipeline safety device, and more specifically, the invention relates to a quick-sealing plate type tank root safety emergency device. Background technique [0002] Today's pipeline valve technology used in the production, storage and transportation of hazardous chemicals is still relatively traditional, and most of its driving methods rely on manpower, hydraulic systems, pneumatic or electric and combined transmission modes. Numerous production practices and accident cases prove that the existing pipeline process valve control technology has problems such as cumbersome mechanical transmission, high failure rate and high dependence on mains power. accidents, and when the pipeline accidentally leaks, explodes and fires, its automatic emergency response function is obviously insufficient. Numerous leakage accident cases such as the explosion and fire of the crude oil pipeline in Dalian on 7.16 and the fire in the tank farm in Ji...

Problems solved by technology

Numerous production practices and accident cases prove that the existing pipeline process valve control technology has problems such as cumbersome mechanical transmission, high failure rate and high dependence on mains power. accidents, and when the pipeline accidentally leaks, explodes and fires, its automatic emergency response function is obviously insufficient. Numerous leakage accident cases such as the explosion and fire of the crude oil pipeline in Dalian on 7.16 and the fire in the tank farm in Jingjiang on 4.22 in Jiangsu have confirmed the potential risks and hidden dangers in the pipeline Internet of Things. ubiquitous

The analysis of the accident found that the escalation and expansion of the disaster were all caused by the failure of the tank root valve and the electric gate valve to close after power failure. It was also because of the dependence of the existing valves on electricity and the lack of emergency automatic response closing function that caused explosions and heavy casualties. Moreover, there is also a lack of automatic emergency avoidance devices on the pipelines of hazardous chemicals, which brings great difficulties to fire control and leads to the escalation and expansion of disasters.
