Description
Technical field
The utility model is related to a kind of washers, more particularly, to a kind of venting of dust explosion washer suitable for profiled sheet.
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.
The venting of dust explosion bolt installed on pressure release wall includes bolt and metal gasket, and gasket is thicker, and intensity is higher, and when installation is not easy
Damage and fracture, however need certain fragility again in pressure release, it is therefore desirable to take into account installation reliability and venting of dust explosion ability.
The Chinese patent of Publication No. CN200820180218 discloses a kind of venting of dust explosion bolt fastening for pressure relief facility
Part, including screw rod and it is set in the metal gasket of the screw head, there is the elasticity being set on screw rod under metal gasket
Gasket, metal gasket are the arcuate structure outwardly protruded, can enhance explosion venting bolt fastener in the case where not increasing depth information
Intensity, while reinforcing explosion venting bolt fastener waterproof effect.But the processing of the gasket of the bolt fastener is complicated, is not suitable for pressing
Template, and can only slightly be tightened when construction, construction precision cannot be controlled well.
Utility model content
The purpose of this utility model is exactly to be provided a kind of suitable for pressure to overcome the problems of the above-mentioned prior art
The venting of dust explosion washer of shape steel plate.
The purpose of this utility model can be achieved through the following technical solutions：
The outer surface of a kind of venting of dust explosion washer suitable for profiled sheet, the venting of dust explosion washer is provided with a plurality of notch, venting of dust explosion
The face that washer is contacted with contour plate is put more energy into muscle equipped with rigidity, and the notch and rigidity muscle of putting more energy into are set around mounting hole
It sets.
Preferably, a plurality of notch is distributed in radiation.
Preferably, a plurality of notch is in M shape.
Preferably, rigidity muscle of putting more energy into is the circumference convex ribs for being fitted around hole.
Preferably, the rigidity put more energy into muscle cross section be semicircular arc.
Preferably, the venting of dust explosion washer is taper faced washer.
Preferably, the venting of dust explosion washer is arch washer.
Preferably, the venting of dust explosion washer is metal gasket.
Compared with prior art, the utility model has the following advantages：
(1) outer surface of venting of dust explosion washer is provided with a plurality of notch, and the face that venting of dust explosion washer is contacted with contour plate adds equipped with rigidity
Strength muscle meets the requirement of bolt installation strength, while meeting venting of dust explosion requirement again, and notch is as weak location, once explosive event goes out
It is existing, gasket rapid damage can be made, be suitable for the venting of dust explosion of profiled sheet.
(2) venting of dust explosion washer is that taper faced washer or arch washer, processing and fabricating are simple.
(3) gasket is frivolous, does not have particular/special requirement (waterproof antirust) to material, galvanized steel plain sheet, aluminium, stainless steel can be used
Equal common metals material.

Specific implementation mode
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, gives detailed embodiment and specific operating process, but the guarantor of the utility model
Shield range is not limited to following embodiments.
Embodiment 1
As shown in Figure 1, 2, a kind of venting of dust explosion washer suitable for profiled sheet, the outer surface of venting of dust explosion washer are provided with a plurality of notch
11, the face that venting of dust explosion washer is contacted with contour plate is put more energy into muscle 12 equipped with rigidity, and notch 11 and rigidity put more energy into muscle 12 along mounting hole
Surrounding is arranged.As shown in Figure 3,4, notch 11 is used as weak location, once explosive event occurs, can make gasket rapid damage,
Play the role of venting of dust explosion；Rigidity muscle 12 of putting more energy into provides good intensity and ensures, ensures the reliability of installation.The present embodiment notch 11
8 are shared, is distributed in M shape, according to the needs of fragility, can flexibly select the item number of notch.
The present embodiment rigidity muscle 12 of putting more energy into is the circumference convex ribs for being fitted around hole, and the put more energy into cross section of muscle 12 of rigidity is semicircle
Arc.
Washer body 1 is taper faced washer.
Venting of dust explosion washer can be used the common metals material such as galvanized steel plain sheet, aluminium, stainless steel and be made.
This washer meets the requirement of bolt installation strength, while meeting venting of dust explosion requirement again, and there is clear index in when installation, twists bolt
To there is resistance, bolt is not only fastened but also gasket will not be destroyed.
Embodiment 2
As different from Example 1, washer body 1 is arch washer, remaining is same as Example 1, practical according to installation
It needs that corresponding washer-shaped may be selected.
