Description

A kind of pressure release window that can reduce indoor explosive damage power

Technical field

The utility model relates to the explosion-proof technology field, particularly a kind of helping just in case play when indoor generation chemistry or physical property explosion accident and induce the pressure release effect, help reducing the pressure release window to building itself and indoor property destructiveness.

Background technology

To the coal oil chemical industry, the common ground of these industries is all to exist explosion-proof protection demand from the high-tech semiconductor industry.

At present, most existing buildings do not have the pressure-relief explosion-proof facility basically, even deposit the warehouse of combustible and explosive articles, factory building or the physical and chemical experiment chamber that produces combustible and explosive articles, special-purpose pressure-relief explosion-proof facility are not set all.Chemistry and physical property blast, comprise the blast of fuel gas, dust and mixed gases, all can produce powerful impact wave moment, destroy building and property on every side, cause causing enormous economic loss and casualties, thereby necessaryly take positive active defensive measure and be provided with just in case help reducing effective facility of destructive power when blasting accident.Enhancing along with people's anti-explosion safety idea, more and more recognize the importance that the pressure-relief explosion-proof facility is set on building, some innovation and creation of having come out in recent years, for example No. 200620089650.9 " a kind of light-duty board-like explosion venting device " utility model patent of China announced passes through to offer special-purpose pressure relief opening on building, and on the metope of the pressure relief opening outside, flange seat is set, one side is set on flange is drawn by theft-resistant link chain, opposite side is by the compressor arm of back-moving spring traction, the spacing steel plate that reaches by the magnet sticking that is arranged on the flange seat oral area of contact roller, meet accident during explosion accident when indoor, room pressure is made every effort to overcome the compressor arm of clothes magnet suction and back-moving spring traction, the spacing power of contact roller, make steel plate break away from the flange seat oral area, realize pressure release, and because the draw of theft-resistant link chain, steel plate can not fly away from, hurt sb.'s feelings, has certain practicality, but because general structure more complicated, special flange seat need be set, and rely on the spacing steel plate that is provided with of magnet on flange seat, flange seat is outer gibbosity and steel plate does not have reasons such as heat insulation function, cause that cost totally is set is higher and inconvenient, the position that can be provided with is limited, and safety is relatively poor, and outer gibbosity is provided with the overall appearance that can influence metope or roofing, in addition, also can influence the insulation that reduces the building that this light-duty board-like explosion venting device is set, sound insulation value, this and current ben energy-conservation, environmental requirement is not inconsistent mutually, be unfavorable for applying, thereby, still owe desirable from practicality and the consideration of economy angle.

Summary of the invention

The purpose of this utility model is to provide a kind of blast to indoor generation to have quick perceptional function, can form fast and have the pressure relief opening of inducing impact wave to efflux, the pressure release window that can effectively reduce indoor explosive damage power.

The pressure release window main body that the utility model can reduce indoor explosive damage power includes window frame, window page or leaf and hinge, comprise in addition and be provided with the venting of dust explosion bolt, wherein: described window frame main body is frame-like, enclose the hollow form housing that forms of system and the blend stop shape inside casing that formed by the rigid metal lath system of enclosing constitutes by the rigid metal section bar, filling is provided with the insulation casting resin in the shape internal voids that constitutes housing; Described window page or leaf main body is made of the inside and outside page, frame face and internal insulation casting resin on every side, the frame face is made by the shape that cross section is " ㄇ " shape on every side, inside and outside page fix is arranged on the curved side in front and back of " ㄇ " shape shape, and the internal insulation casting resin is arranged in the inner space that is made of the shape of " ㄇ " shape and the front and back page; Described hinge is filled the post of by the stainless steel hinge; Described venting of dust explosion bolt is that the venting of dust explosion special bolt of 20psf is filled the post of by ultimate strength.In addition, described insulation casting resin can be filled the post of by the high density rock wool; The page can preferentially adopt galvanized iron sheet or glass wool board in described; The described outer page preferentially adopts aluminium alloy plate, corrosion resistant plate or glass wool board; Described shape preferentially adopts aluminum alloy material.

Under installment state, described window frame is fixedly installed on by self-tapping screw on the window keel of building, between described window page or leaf and the window frame by correspondence be arranged on the frame face of window page or leaf with hinge assembling activity on the window frame housing respective inner link to each other, by the weather strip sealing between the blend stop of the interior page that is arranged on the window page or leaf and inside casing, and link to each other with low-intensity assembling connecting piece venting of dust explosion bolt assembling between window frame inside casing blend stop by being arranged on the page in the window page or leaf.

Can reduce the pressure release window of indoor explosive damage power based on the utility model of above-mentioned design, because being provided with by ultimate strength between window frame and window page or leaf is the low-intensity assembling connecting piece that 20psf venting of dust explosion bolt is filled the post of, when room pressure during near 20psf, the venting of dust explosion bolt i.e. fracture automatically, the window page or leaf is promptly outwards opened automatically, so on building, form smooth open type pressure relief opening fast, the impact wave that blast forms just can outwards discharge at once through pressure relief opening, so the destructive power that indoor blast is produced drops to minimum; And because the activity of hinge and reliable interconnect function, the window page or leaf just departs to be opened, generally speaking can be not impaired, neither can break away from window frame, can be to property and personnel component threaten on every side yet, the window page or leaf can be reused, as long as on the position of damaging the venting of dust explosion bolt, reinstall the venting of dust explosion bolt is set, can restore to the original state and original function; And set venting of dust explosion window self has heat insulation, insulation and sound insulation function, and can take into account surperficial whole anastomose property with the building indoor and outdoor, so after pressure release window of the present utility model is set, can not influence the allomeric function and the aesthetic of building itself, not only can be used for storing or producing on the warehouse or factory building of combustible and explosive articles, but also can be used for physical and chemical experiment, experimental area other civil buildings in one's power as required, the position is set can arbitrarily be selected, not only can be arranged on every side on the body of wall, and can be arranged on the roof.In sum, that venting of dust explosion window of the present utility model has is simple in structure and scientific and reasonable, be provided with convenient and random strong, the reliable operation in position is set and safety good, do not recover characteristics easily after the aesthetics of wall face and body of wall function and the work in can not influencing after being provided with, form that can the standard universal accessory is made the series of products that can select for use for building trade, thereby has extremely obvious practicability and valuable market application foreground.
