Life security is produced greatly to be damaged, and in order to avoid accidental explosion does great damage to whole building thing, current common practice exists
Parking space region arranges the explosion venting devices such as explosion relief door, explosion release window, but traditional explosion relief door, explosion release window response speed are slow,
Belong to disposable breaking plant, pressure leak process is not smooth enough, and effect is not ideal enough.As explosion venting device needs to bear and resist by force
Big impulsive force, it tends to be difficult to make large scale specification, has both met venting of dust explosion requirement while and meeting the need that personnel and goods are passed in and out
Will.
Below by the concrete analysis to several prior arts, so that the weak point in the presence of prior art to be described, with
And technical problems to be solved in this application.
1. explosion relief door（Authorization Notice No. CN 2890288Y）
The utility application designed by inventor's Zhang Wenming, it discloses a kind of explosion relief door, and the explosion proof door is main
Comprising doorframe and door-plate, wherein, doorframe is fixed on body of wall and comprising upper frame body, middle framework and lower frame body, and door-plate passes through hinge
Afterwards with doorframe, upper frame body be connected, constitute an explosion relief door, when indoor generation air blasting, venting of dust explosion bolt because of pressure moment break
Split, and then make door-plate unlatching is pushed outwardly as fulcrum by air blasting pressure with hinge, and when door-plate is in closed mode at ordinary times, then lead to
Cross the fit portion of doorframe upper frame body and middle framework, and the closing portion of door-plate be inclined upwardly with middle framework, lower frame body slope,
Closing, to constitute bridging effect, and then the waterproof effect for reaching.
The utility model exists following not enough：
On explosion relief door is by blast shock surface, its doorframe and the upper frame body for being included, middle framework, lower frame body are then fixed on
On body of wall, this area accounts for the 30-40% of the face gross area that is hit, and it has impact on effective release of shock wave energy so that have
Effect open area reduces；When being subject to blast to impact, as open area is less, upper frame body, middle framework and lower frame certainly will be caused
Body is integrally rushed open by shock wave, causes explosion relief door irrecoverability to destroy.
2. plus-minus differential pressure overpressure alarming venting door（Authorization Notice No. CN 201026430Y）
