Description
Technical field
The present invention relates to anti-explosion safety technical field more particularly to a kind of explosion relief doors.
Background technique
Explosion relief door is a kind of moment of generation of exploding indoors, rapidly from opening, to outdoor excretion blast pressure rapidly, is reduced
A kind of door body of explosive forces, is mainly used for industrial building, research institute etc., can effective guarantee human life safety, ensure
Building interior Plant in good condition ensures that building overall structure is intact, is not endangered by explosion wave, while explosion danger being prevented to prolong
It is continuous.
If Chinese patent CN205135323U discloses a kind of explosion relief door, including venting of dust explosion door body, venting of dust explosion door body includes
The side of two pieces of zinc-plated cold-rolled steel sheets and the fireproof material layer between two pieces of zinc-plated cold-rolled steel sheets, venting of dust explosion door body is equipped with circle
Thrust bearing four-way adjustable door heel is bored, explosion relief door is equipped with several venting of dust explosion wickets, and venting of dust explosion wicket is equipped with venting of dust explosion building blocks of function, venting of dust explosion
Door body is equipped with venting of dust explosion escape lock.Wherein, venting of dust explosion formation function includes venting of dust explosion bolt, traction strand cable and stainless steel loose-leaf.This
A kind of explosion relief door that utility model provides, by the venting of dust explosion building blocks of function on setting venting of dust explosion wicket and venting of dust explosion wicket, thus when dress
When having the indoor generation accidental explosion of the explosion relief door, venting of dust explosion formation function can involve pressure with automatic sensing blast impulse, when quick-fried
When fried impact involves pressure and reaches the venting pressure value being pre-designed, venting of dust explosion wicket is made automatically, rapidly excretion explosion pressure outward
Power, and then avoid the massive losses of indoor occupant life and property.
For another example Chinese patent CN2890288Y discloses a kind of explosion relief door, including doorframe, which is provided with upper, middle and lower framework,
It is equipped with the set portion of recess appropriate depth upwards in the upper frame body and the root edge of middle framework, and in wherein framework and the leading edge of lower frame body
Equipped with slope；Two door-plates are equipped with single order portion in top leading edge, and are equipped in lower section leading edge and correspond to framework, lower frame in doorframe
The inward slant closing portion on body slope；By the combination of aforementioned components, two plate of door is in top rank portion with hinge and doorframe upper ledge
The fitting portion connection of body, middle framework, to constitute an explosion relief door.In explosion relief door above-mentioned, the middle framework of the doorframe.Lower frame body in
Slope rear is equipped with a vertical stator, and venting of dust explosion bolt is locked on rear below door-plate after wearing the vertical stator, works as gas explosion
When, door-plate is opened outward by the fracture of bolt.The utility model patent is due to taking the above design, when indoor generation gas gas
It when quick-fried, is able to open on door-plate, and framework is eliminated by the ramp-like closing portion in the fitting portion of framework and door-plate when usually closing
With the gap of door-plate, to reach waterproof effect.In addition, can also be closed back after door-plate is turned on and lock venting of dust explosion bolt again,
Restore the function of explosion relief door.
But explosion relief door disclosed in above-mentioned two utility model patent only has the function of timely pressure release, is not provided with just
In the structure of emergency escape, although decompression function can be being reached at the first time, it is not easy to indoor occupant and withdraws.
Summary of the invention
