Full-automatic gate plate type risk avoiding device

Abstract

The invention discloses a full-automatic gate plate type risk avoiding device. The full-automatic gate plate type risk avoiding device is mainly characterized by comprising a valve deck; magnetic suction cups are arranged in the valve deck; the lower portion of the valve deck is connected with a gate valve body; gear devices are arranged at the top of the gate valve body and connected with a hanger capable of moving up and down; the hanger comprises a push plate; the push plate is connected with a valve plate capable of being attracted by the magnetic suction cups; the lower portion of the gate valve body is provided with a flange plate communicated with a pipeline; a channel matched with the valve plate is formed in the center of the flange plate. By the adoption of the technical scheme, a screw rod is separated from the valve plate after the valve plate is locked through magnetic force, and the valve plate falls rapidly to close a valve by means of gravity, and thus automatic risk avoiding when fires occur due to leakage is achieved. The full-automatic gate plate type risk avoiding device can be installed on the pipeline or the tank root of a hazardous chemical substance storage tank and is capable of rapidly handling potential emergent leakage accidents. The full-automatic gate plate type risk avoiding device can also be installed on a section pipe network node of a long-distance-transportation pipeline distribution station, is in an emergency standby state and is capable of preventing hazardous chemical substance media from leakage at the dangerous moment and avoiding accident expansion and environment pollution so as to reduce the property loss.

Description

technical field [0001] The invention relates to the technical field of valve emergency driving devices, in particular to a fully automatic gate-type safety avoiding device. Background technique [0002] At present, the pipeline valve technology currently used in the production, storage and transportation of hazardous chemicals is relatively primitive, and most of the driving methods rely on manpower, hydraulic systems, gas storage pneumatic systems or electric and combined transmission modes. Numerous production practices and accident cases prove that the existing pipeline process valves The control technology has high requirements for mechanical transmission, high failure rate, high maintenance cost, high support cost and high dependence on mains power. At the same time, its own hidden dangers also bring new safety problems to process control, especially in the field and fire It is difficult to guarantee the reliability of automation functions in dangerous areas such as dan...

[0002] At present, the pipeline valve technology currently used in the production, storage and transportation of hazardous chemicals is relatively primitive, and most of the driving methods rely on manpower, hydraulic systems, gas storage pneumatic systems or electric and combined transmission modes. Numerous production practices and accident cases prove that the existing pipeline process valves The control technology has high requirements for mechanical transmission, high failure rate, high maintenance cost, high support cost and high dependence on mains power. At the same time, its own hidden dangers also bring new safety problems to process control, especially in the field and fire It is difficult to guarantee the reliability of automation functions in dangerous areas such as dangerous areas. The explosion and fire of crude oil pipelines that have occurred in the past were all caused by the failure of the electric gate to be closed after power failure, resulting in the leakage of crude oil, which not only ignited a 100,000 cubic meter oil tank, but also caused One of the key factors for the occurrence of this major accident is the lack of professional preventive equipment for emergency automatic control devices and emergency avoidance in the setting of crude oil pipelines.
