A fully automatic ram type safety avoidance device

Abstract

A fully automatic gate-type safety device, the technical points of which are as follows: a bonnet is provided with a magnetic sucker, the lower part of the bonnet is connected with a gate valve body, and the top of the gate valve body is provided with a gear device, which is connected with a The hanger that moves up and down, the hanger includes a push plate, the push plate is connected with a valve plate that can be attracted by a magnetic suction cup, the lower part of the gate valve body is provided with a flange connected to the pipeline, and the center of the flange is provided with a valve plate Matching channels; with this technical solution, the screw rod is separated from the valve plate after the valve plate is magnetically locked, and the valve plate only relies on gravity to quickly drop and close the valve, which automatically avoids danger in case of leakage and fire. , can quickly solve the possible sudden leakage incidents in the pipeline transportation process, installed on the pipeline network node of the distribution station of the long-distance pipeline, in the emergency standby state, to block the leakage of hazardous chemical media at dangerous times, and prevent accidents from expanding and Environmental pollution to reduce property damage.

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...

Problems solved by technology

[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.
