Fireproof valve capable of realizing automatic and quick close in case of failed electronic installations

Abstract

The invention relates to a fireproof valve capable of realizing automatic and quick close in case of failed electronic installations. The fireproof valve comprises a valve body, a valve core, a valve cover, a valve rod and a valve bracket, wherein the valve core is arranged in the valve body, the top end of the valve core and the valve rod are coaxially fixed together, the valve cover is coaxially arranged on the valve body, the valve bracket is coaxially arranged on the valve cover, an ESFR quick response system is horizontally arranged on the side wall of the valve bracket, the front end of the ESFR quick response system is embedded into the side wall of the valve rod, a closed spring is sleeved on the valve rod in the valve bracket, the side wall at the upper end of the valve rod is provided with a coupling pin hole movably connected with a return mechanism of the valve rod, and the return mechanism of the valve rod is coaxially arranged on the valve bracket. In case of fire accidents, the fireproof valve can realize automatic close, so that the leakage of oil products is quickly cut off; and the valve has the characteristics of high accuracy, high stability, flexible assembly and disassembly, convenient use and the like, and when the valve is arranged on an oil pipeline, the violent spread of fire can be effectively prevented, and the explosive accidents are also avoided.

Description

technical field [0001] The invention belongs to the field of valves, in particular to a fire-proof valve that can be automatically and quickly closed when power damage facilities fail. Background technique [0002] In recent years, fire and explosion accidents in petrochemical parks in my country have generally shown an upward trend. Fire and explosion accidents in some large chemical enterprises and chemical stations have also occurred frequently, which not only caused a large number of casualties and property losses, but also caused large-scale river and ocean pollution. Seriously Affect our country's economic development and social stability. At present, the valves on the pipelines of petrochemical parks are usually driven by manual driving or electric actuators. The problems of manual driving are: in the event of a fire, it is difficult for operators to enter the fire scene to close the valves; electric actuators are used. The problem with the method is: whether it is el...

AI Technical Summary

Problems solved by technology

At present, valves on pipelines in petrochemical parks are usually driven manually or by electric actuators. The problems with manual actuation are: in the event of a fire, it is difficult for operators to enter the fire site to close the valves; The problem with the method is: no matter it is the electric method, pneumatic method, hydraulic method or electro-hydraulic linkage method, when the power system is damaged, the electric actuator loses the ability to drive and control the valve and cannot close the valve, resulting in a large amount of oil. The flow makes the fire continue to expand, and even an explosion accident occurs
