Description

A kind of venting of dust explosion securing member
Technical field
This utility model is related to venting of dust explosion connector field, more particularly, to a kind of venting of dust explosion securing member.
Background technology
, generally in industrial civilian Factory Building boiler room, the lightweight pressure release body of wall of the application such as dangerous goods store, in building for venting of dust explosion wall When the generation blast of thing interior or burning, gas pressure steeply rises therewith within doors, and explosion releasing wall makes wall by venting of dust explosion accessory or device Body is opened and is discharged pressure, to control the generation of blast or to make destructiveness reach minimum.
Venting of dust explosion accessory is generally made up of venting of dust explosion bolt and traction strand cable, and wherein, the effect of venting of dust explosion bolt is to quantify venting pressure Value, dynamic control discharges pressure.
As Chinese patent CN201982746U discloses pressure relief bolt connecting device, including screw mandrel and nut, nut and silk Bar is spirally connected, and one end of screw mandrel is provided with end cap, and the outer surface of screw mandrel is provided with least one groove, and the section of groove is triangle or four Side shape or semicircle.After the technical scheme being disclosed using this patent, pressure relief bolt connecting device arranges groove by screw mandrel surface, When unexpected generation, internal pressure steeply rises, and to during more than screw mandrel ability to bear, screw mandrel fracture failure is so that this bolt connection Manhole cover that device is connected etc. automatically opens up, and provides the pressure relief opening release of pressure of larger area, thus avoiding exploding.But, this is special The pressure relief bolt connecting device that profit discloses, it is equally easily broken off in installation process, and therefore, destructive rate is high, increased and scraps Rate.
And for example Chinese patent CN101749463A discloses the explosion venting bolt fastener for pressure relief facility, including screw rod and It is set in the metallic gasket of screw head, under metallic gasket, also have one to be set in the elastomeric pad on screw rod, wherein, metallic gasket For outwardly arcuate structure, elastomeric pad has and metallic gasket identical arc mechanism, and is close under metallic gasket. Wherein, arcuate structure is spherical structure, and elastomeric pad is rubber sheet gasket, and the end of screw rod has from tap holder, the material of metallic gasket Matter is aluminum.Technical scheme disclosed in this utility model patent, because metallic gasket adopts arcuate structure, can play certain pre- Clamp force acts on, and therefore, when mounted, as long as somewhat tightening, greatly reduces the destructive power to metallic gasket.Blast occurs When, when indoor pressure reaches predetermined value, metallic gasket and cushion sector-meeting warpage automatically together.Deformation, thus cause pressure release Facility exterior wall comes off, and forms a unlimited space, makes the pressure of interior lead outdoor outward rapidly, it is to avoid interior of building material thing And the destruction of building mechanism itself.But, when blast occurs, sheet material is subject to huge shock wave, easily occurs explosion existing As, and adopt the explosion venting bolt fastener of the pressure relief facility of this utility model disclosure, sometimes it is difficult to be rapidly reached pressure release effect.
Utility model content
For overcoming problems of the prior art, this utility model provides one kind and is quick on the draw, being capable of pressure release rapidly A kind of venting of dust explosion securing member.
, it is characterised in that including fastener body, described securing member is originally for a kind of venting of dust explosion securing member that this utility model provides Body includes venting of dust explosion seat and screw rod, and described venting of dust explosion seat is flexibly connected with described screw rod, and described venting of dust explosion seat includes venting of dust explosion seat termination, described The end cap that venting of dust explosion seat termination includes termination sleeve and is located at described termination sleeve one end, described end cap and described termination sleeve Overall for one, described termination point casing jacket casing is outside described screw rod one end and by venting of dust explosion bindiny mechanism, described screw rod one end is solid In the sleeve of described termination.
In some embodiments, described venting of dust explosion bindiny mechanism includes:Hole clipping and institute that described termination sleeve one end opens up State the annular slot that screw rod one end opens up, described annular slot is circumferentially disposed along described screw rod, described venting of dust explosion bindiny mechanism also wraps Include card bead, described card bead is arranged in the hole clipping of described termination sleeve and the draw-in groove of described screw rod, realize described venting of dust explosion seat termination Connection with described screw rod.
In some embodiments, along described termination point casing barrel dliameter to opening up, the longitudinal section of described hole clipping becomes described hole clipping " convex " shape, and the less one end in described hole clipping aperture is inside the sleeve of described termination.Thus, when card bead is in hole clipping, It is unlikely to make card bead pass through hole clipping.
In some embodiments, including hole clipping at least one described.
In some embodiments, including hole clipping described at least two, described hole clipping is along described termination sleeve circumference cyclization Shape is uniformly distributed.Thus, make card bead to screw rod outer wall uniform force application it is ensured that termination sleeve is parallel with screw rod, prevent from offseting.
In some embodiments, the pore size at the larger position in described hole clipping aperture be not less than described card bead diameter big Little, the pore size of described hole clipping aperture smaller part position is less than the diameter of described card bead, and the depth of described hole clipping is less than institute State the diameter of card bead.Therefore so that card bead is unlikely to pass through in hole clipping;As a new step preferably, the depth of hole clipping is less than The diameter of card bead, therefore, after card bead is arranged in hole clipping, makes a card bead part be exposed to outside the sleeve outer wall of termination, another portion Divide and be exposed to termination sleeve inner wall.
In some embodiments, the cross section camber of described annular slot.Thus, it is easy to card bead and slip into card along cambered surface In groove.
In some embodiments, described venting of dust explosion bindiny mechanism also includes outer sleeve and spring strut, and described spring strut is sheathed Outside the sleeve of described termination, described outer sleeve is sheathed on outside described spring strut, and described outer sleeve inwall is provided with annular card division, described The thickness H of annular card division be more than described hole clipping between card bead and described outer sleeve inwall apart from L.Hereby it is achieved that by spring strut It is positioned compressive state.
In some embodiments, the annular card division in described outer sleeve is provided with down towards the edge of described end cap side Angle or be arcwall face.Thus, it is easy to card bead and streak annular card division along fillet surface or arcwall face.
In some embodiments, described end cap and the side of described termination sleeve connection are provided with round table-like step, institute One end diameter stating round table-like step towards described outer sleeve is less.
Compared with prior art, compared with prior art, its advantage exists a kind of venting of dust explosion securing member that this utility model provides In:A kind of venting of dust explosion securing member that this utility model provides, the moment occurring in blast, is impacted by explosive forces, makes venting of dust explosion seat It is rapidly separated with screw rod, so that connecting portion comes off, rapid pressure release, and because venting of dust explosion seat is located at outside sheet material, therefore letting out Do not destroy sheet material during pressure, keep the integrity of sheet material.
