Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the present invention.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
Refer to Fig. 1 and Fig. 2, it is respectively structural representation and the A-A direction view of a kind of pressure relief device of the present invention.Pressure relief device as illustrated in figs. 1 and 2, it comprises base 1, Cut Block 2, sealing cover 3, first fixed end 4, second fixed end 5 and the pressure release latch fastener 6 parallel with the second fixed end 5, and wherein, in figure, the direction of arrow is Impact direction.
Described base 1 is arranged on described first fixed end 4, described base 1 offers the blind round hole 11 holding described pressure release latch fastening devices 6.In this embodiment, the material of described base 1 is that stainless steel or carbon steel are zinc-plated, described base 1 is fixed on described first fixed end 4 by hex bolts 7, and in other embodiments, described base 1 can also be that other modes are fixed on described first fixed end 4.
Described Cut Block 2 is arranged on the second fixed end 5 vertical with described first fixed end 4, and on described Cut Block 2, corresponding blind round hole 11 place offers the manhole 21 penetrated for pressure release latch fastening devices 6.Between described Cut Block 2 and base 1 spaced a predetermined distance.In this embodiment, the material of described Cut Block 2 is that stainless steel or carbon steel are zinc-plated, described Cut Block 2 is fixed on described second fixed end 5 by hex bolts 7, and in other embodiments, described Cut Block 2 can also be that other modes are fixed on described second fixed end 5.
Refer to Fig. 3, it is the structural representation of pressure release latch fastener in Fig. 1.Pressure release latch fastener as described in Figure 3 comprises the first plug pin portion 61, second plug pin portion 62 and is positioned at the fracture portion 63 in the middle of described first plug pin portion 61 and the second plug pin portion 62, and described fracture portion 63 is between described base 1 and Cut Block 2.Described fracture portion 63 to extend internally formation from the first plug pin portion and the second plug pin portion 62, and this fracture portion 63 comprises transition 631 and column part 632.The length in described fracture portion 63 is equal with the distance between described base 1 and Cut Block 2.The diameter in described fracture portion 63 is less than the diameter of described first plug pin portion and the second plug pin portion.As shown in figures 1 and 3, during use, described second latch 62 is inserted manhole 21 until the first plug pin portion 61 enters in the blind round hole 11 of base 1 from Cut Block 2 upper end, just described first fixed end 4, second fixed end 5, base 1 and Cut Block 2 are linked to be a closed entirety by pressure release latch fastener 6 like this, finally use self-tapping screw to be fixed on by sealing cover 3 on base 1 side to cover base 1 and Cut Block 2, play attractive in appearance, dust-proof effect.In this embodiment, the material of described pressure release latch fastener 6 is copper, and the material of described sealing cover is that stainless steel or carbon steel are zinc-plated.The pressure release value of described pressure release latch fastener 6 is that 20PSF-60PSF(1PSF equals 47.85Pa).In other embodiments, can according to different places, impact in conjunction with local positive and negative blast, different dangerous matter sources formulates suitable pressure release value, thus can reach better explosion-proof relief effect.
Please continue to refer to Fig. 1, one end of described first fixed end 4 is connected with base 1, and the other end is connected in building structure (not shown).Second fixed end 5 is connected with Cut Block 2, and described second fixed end 5 is main stress areas of pressure relief device, and Impact direction as shown by arrows.In this embodiment, described first fixed end 4 and the second fixed end 5 are two independently individualities, in other embodiments, first fixed end 4 and the second fixed end 5 also can link together, but when pressure relief device is stressed need pressure release time, described first fixed end 4 and the second fixed end 5 suitable being split up into easily.
Pressure relief device of the present invention be mainly used in the facility needing its pressure release effect in the industries such as petrochemical industry, pharmacy, high-tech semiconductor, concrete facility includes but are not limited to the architectural exterior-protecting constructions such as pressure port, pressure release window, pressure release wall and pressure release roofing.
Refer to Fig. 4, it is the present invention's operating principle schematic diagram in one embodiment.For pressure release window, operating principle of the present invention is described below: when blasting in indoor, indoor pressure can conduct to rapidly on the second fixed end 5, then the second fixed end 5 again pressure conduction on pressure release latch fastener 6, conduct on base 1 and the first fixed end 4 more further by pressure release latch fastener 6, in the transmittance process of pressure, pressure release latch fastener 6 is subject to shear action.When blast pressure reaches its critical slope langth power to the shearing force that pressure release latch fastener 6 produces, will shear failure be there is in the fracture portion of pressure release latch fastener 6, now Cut Block 2 will separate with base 1, second fixed end 5 moves along Impact direction together with Cut Block 2 meeting, then the second fixed end opens an open space along opening direction, open space is once mineralization pressure will be spread to outdoor buildings by it, thus Indoor environment blast, the pressure that detonation produces will reduce rapidly, avoid the destruction of fabric structure and the loss of indoor property and casualties.In the present invention, pressure release latch fastener can be changed according to actual conditions, by the size regulating the critical slope langth power of pressure release latch fastener can control pressure release value, thus it is effective from numerically having quantized pressure release value, can according to different places in practice, different dangerous matter sources formulates suitable pressure release value, thus can reach better explosion-proof relief effect.
A kind of pressure relief device of the present invention, it breaches traditional pressure release, by pressure release latch fastening devices effectively from numerically having quantized pressure release value, ensure that under certain concrete force value state, open rapidly pressure relief facility is transmitted to building outside fast by pressure, be conducive to reducing blast pressure to the destruction of building and consequent casualties and property loss.Pressure relief device of the present invention, can according to different places in practice, and different dangerous matter sources formulates suitable pressure release value, thus safer, more effectively reach explosion-proof relief effect.
Above-mentioned explanation fully discloses the specific embodiment of the present invention.It is pointed out that the scope be familiar with person skilled in art and any change that the specific embodiment of the present invention is done all do not departed to claims of the present invention.Correspondingly, the scope of claim of the present invention is also not limited only to previous embodiment.
