The application for a patent for invention designed by inventor Senlin Special Steel Door Co., Ltd., Shanghai, relates to deposit excessive risk
The building gateway of harmful influence or the shock resistance steel venting of dust explosion rolling screen door design of passage, it is possible to avoid or weaken what blast produced
The damage that building is caused by shock wave, provides effective guarantee for property and personal security.
This shock resistance steel venting of dust explosion rolling screen door, mainly includes curtain face, open-type guide rail, when by blast impulse, first
First venting of dust explosion bolt is severed, and open-type guide rail venting of dust explosion portion rotates around hinge, presents unlatching shape, and the roller shutter shop front is destroyed also by shock wave
Release outdoor, play preferable venting of dust explosion, decompression function.This venting of dust explosion rolling screen door simultaneously, is prone to when usually using open and close, it is achieved big chi
The requirement of very little current door.
This patent of invention exists following not enough:
(1) in steel venting of dust explosion rolling screen door by blast shock surface, on it, shutter door casing and both sides open-type guide rail are consolidated
Being scheduled on body of wall, this area accounts for the 10-20% of the face gross area that is hit, and it has impact on effective release of shock wave energy,
When being impacted by blast, owing to open area is less, shutter door casing and both sides open-type guide rail certainly will be caused by shock wave
Rush open, cause explosion relief door irrecoverability to destroy.
(2) the venting of dust explosion principle of steel venting of dust explosion rolling screen door is for disposably destroying venting of dust explosion, and after accident occurs, its curtain face is damaged completely,
Flue dust and poison gas that blast produces are released to space outerpace, and neighboring buildings and other staff are worked the mischief by this.
4. fire-extinguishing explosion relief valve (patent No. ZL 94229292.8)
The utility application designed by inventor Northeastern University, belongs to the venting of dust explosion test of industrial dust detonation
Device.This testing equipment is mainly made up of base, upper cover, venting of dust explosion piston and venting of dust explosion fence, and its operation principle is when in closed container

Pressure sensor 5 can sense the ANOMALOUS VARIATIONS of room pressure, when pressure sensor 5 senses that room pressure is different
When often raising, alert and resourceful for drive formula venting of dust explosion bolt 7 is exited lockhole by pressure sensor 5, releases the locking to door leaf 2 in very short time
And constraint, make pressure leak process rapidly, fast.
As shown in Fig. 5, Fig. 6 and Fig. 7, pressure sensor 5 includes being embedded in upper transverse frame 1-1 medial surface and having resilient
Pressure sensitive plate 5-2 and fix the inductor connecting plate 5-7 being connected with pressure sensitive plate 5-2 medial surface center.This inductor
The first horizontal rack 5-5 being meshed with driving wheel 7-13 it is provided with on connecting plate 5-7.
The pressure sensitive value of above-mentioned pressure sensitive plate 5-2 can regulate, it is thus possible to realize to different venting of dust explosion peak values at any time
Regulation.The pressure sensitive value of pressure sensitive plate 5-2 has the concrete regulative mode of the following two kinds.
1., by regulating the length of pressure sensitive plate 5-2, regulate the pressure sensitive value of pressure sensitive plate 5-2.Feeling of stress
The length adjustment mode answering plate 5-2 is: is provided with rail plate 5-4 at the two ends of pressure sensitive plate 5-2 and is positioned at slip and leads
Sliding wheel 5-3 in rail 5-4.The locked position of regulation sliding wheel 5-3, can regulate pressure sensitive plate 5-2 as required
Length.
2., by changing the elastic model of pressure sensitive plate 5-2, regulate the pressure sensitive value of pressure sensitive plate 5-2.As
To be set to removably connect between pressure sensitive plate 5-2 and doorframe 1, it is also possible to for the first rail plate 5-4 and slip
The connection of guide wheel 5-3.
By above-mentioned regulative mode, according to the requirement of maximum venting of dust explosion superpressure value, it is possible to arbitrarily adjust the pressure of pressure sensor 5
Power sensing threshold value, thus venting pressure induction sensitivity is adjusted, can effectively let out except room pressure, and in design pressure
Automatic alarm in induction range, automatically turns on venting of dust explosion door and window, it is achieved decompression discharge.
Above-mentioned inductor connecting plate 5-7 is additionally provided with the first level slip limit guide groove 5-1, alarming trigger switch guide groove 5-
8 and be positioned at the alarming trigger switch 5-6 of alarming trigger switch guide groove 5-8.First level slip limit guide groove 5-1 can be to sensing
The level slip of device connecting plate 5-7 carries out spacing.
Above-mentioned pressure sensitive plate 5-2, when being not affected by blast impulse, is in original state as shown in Figure 5.Work as feeling of stress
Answering plate 5-2 to experience indoor and have inflammable substance explosion time, explosion wave will act on pressure sensitive plate 5-2.Due to pressure
Tablet 5-2 two ends are limited jointly by sliding wheel 5-3 and rail plate 5-4 so that plate 5-2 is outside in pressure sensitive
Side deforms, deformation state after the ripple that is hit, as shown in Figure 6.
