Description
Technical field
The present invention relates to venting of dust explosion connector field more particularly to a kind of venting of dust explosion fasteners.
Background technology
Venting of dust explosion wall usually in the civilian workshop boiler room of industry, building by the lightweight pressure release wall of the applications such as dangerous goods store
Gas pressure steeply rises therewith within doors when explosion or burning occurring in object room, and explosion releasing wall makes wall by venting of dust explosion accessory or device
Body is opened and is released stress, and with the generation of control explosion or extent of the destruction is made to reach minimum.
Venting of dust explosion accessory is usually made of venting of dust explosion bolt and traction strand cable, wherein the effect of venting of dust explosion bolt is quantization venting pressure
Value, dynamic control release stress.
As Chinese patent CN201982746U discloses pressure relief bolt connecting device, including lead screw and nut, nut and silk
Bar is spirally connected, and one end of lead screw is equipped with end cap, and the outer surface of lead screw is equipped at least one groove, and the section of groove is triangle or four
Side shape or semicircle.After the technical solution disclosed using the patent, groove is arranged by lead screw surface in pressure relief bolt connecting device,
When unexpected generation, internal pressure steeply rises to more than when lead screw ability to bear, lead screw fracture failure so that this is bolted
The manhole cover etc. that device is connected automatically opens, and provides the pressure relief opening release of pressure of larger area, to avoid exploding.But this is specially
The pressure relief bolt connecting device that profit discloses, is equally easily broken off during the installation process, and therefore, destructive rate is high, increases and scraps
Rate.
For another example Chinese patent CN101749463A discloses the explosion venting bolt fastener for pressure relief facility, including screw rod and
It is set in the metal gasket of screw head, also has an elastomeric pad being set on screw rod under metal gasket, wherein metal gasket
For the arcuate structure outwardly protruded, elastomeric pad has arc identical with metal gasket mechanism, and is tightly attached under metal 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 metal gasket
Matter is aluminium.The technical solution of patent disclosure of the present invention can play certain pretightning force since metal gasket uses arcuate structure
Effect, therefore, when mounted, as long as slightly tightening, greatly reduces the destructive power to metal gasket.When explosion occurs, when
When indoor pressure reaches predetermined value, metal gasket and elastomeric pad can automatic warpages together.Deformation, to cause outside pressure relief facility
Wall falls off, and forms an open space, makes indoor pressure is outer rapidly to lead to outdoor, avoids interior of building material object and build
Build the destruction of mechanism itself.But when exploding generation, by huge shock wave blasting phenomena is easily occurred for plank, and adopts
With the explosion venting bolt fastener for the pressure relief facility that the invention discloses, it is difficult to be rapidly reached pressure release effect sometimes.
Invention content
To overcome problems of the prior art, the present invention provides one kind to be quick on the draw, and is capable of the one of rapid pressure release
Kind venting of dust explosion fastener.
A kind of venting of dust explosion fastener provided by the invention, which is characterized in that including fastener body, the fastener body packet
Venting of dust explosion seat and screw rod are included, the venting of dust explosion seat is flexibly connected with the screw rod, and the venting of dust explosion seat includes venting of dust explosion seat end, the venting of dust explosion
Seat end includes end sleeve and the end cap positioned at end sleeve one end, and the end cap is one with the end sleeve
Whole, the termination point casing jacket casing is set to outside described screw rod one end, and is fixed on described screw rod one end by venting of dust explosion bindiny mechanism
In the end sleeve.
In some embodiments, the venting of dust explosion bindiny mechanism includes：The card hole and institute that end sleeve one end opens up
The annular slot that screw rod one end opens up is stated, the annular slot is circumferentially disposed along the screw rod, and the venting of dust explosion bindiny mechanism also wraps
Card bead is included, the card bead is arranged in the card hole of the end sleeve and the card slot of the screw rod, realizes venting of dust explosion seat end
With the connection of the screw rod.
In some embodiments, the card hole along the termination point casing barrel dliameter to opening up, the longitudinal section of the card hole at
" convex " shape, and the smaller one end in the card hole aperture is located on the inside of the end sleeve.As a result, when card bead is set in card hole,
It is unlikely to that card bead is made to pass through card hole.
In some embodiments, including at least one card hole.
In some embodiments, including at least two card holes, the card hole are circumferential cyclic along the end sleeve
Shape is uniformly distributed.Make card bead to screw rod outer wall uniform force application as a result, ensures that end sleeve is parallel with screw rod, prevent from deviating.
In some embodiments, the pore size at the larger position in card hole aperture is big not less than the diameter of the card bead
Small, the pore size of the card hole aperture smaller part position is less than the diameter of the card bead, and the depth of the card hole is less than institute
State the diameter of card bead.Therefore so that card bead is unlikely to pass through out of card hole；Preferred as a new step, the depth of card hole is less than
Therefore the diameter of card bead after card bead is arranged in card hole, makes a card bead part be exposed on the outside of the sleeve outer wall of end, another portion
Divide and is exposed to end sleeve inner wall.
In some embodiments, the cross section camber of the annular slot.It is convenient for card bead to slide into along cambered surface as a result, to block
In slot.
In some embodiments, the venting of dust explosion bindiny mechanism further includes outer sleeve and spring strut, and the spring strut is arranged
In outside the end sleeve, the outer sleeve is sheathed on outside the spring strut, and the outer sleeve inner wall is equipped with annular card division, described
The thickness H of annular card division is more than card bead distance L between the outer sleeve inner wall in the card hole.Hereby it is achieved that by spring strut
It is positioned at compressive state.
In some embodiments, the edge of the annular card division in the outer sleeve towards the end cap side is equipped with
Angle is arcwall face.As a result, annular card division is streaked along fillet surface or arcwall face convenient for card bead.
In some embodiments, the side of the end cap and the end sleeve connection is equipped with round table-like step, institute
One end diameter for stating round table-like step towards the outer sleeve is smaller.
Compared with prior art, a kind of venting of dust explosion fastener provided by the invention compared with prior art, the advantage is that：This
A kind of venting of dust explosion fastener provided is provided, in the moment that explosion occurs, is impacted by explosive forces, keeps venting of dust explosion seat and screw rod rapid
Separation, to make connecting portion fall off, rapid pressure release, and since venting of dust explosion seat is located on the outside of plank, during pressure release
Plank is not destroyed, the integrality of plank is kept.
