Resetting means installs venting of dust explosion plate；Whole Y type elongnated building devices are installed on fuel gas and dust transfer pipeline, the first connecting tube and the
Two connecting tubes connect transfer pipeline, ensure that pipeline normally conveys operation, connect when with the first connecting line and the second connecting line
Explosion time occurs for logical conveyance conduit, and when blast pressure is more than difference detonating fusee venting pressure, venting of dust explosion plate ruptures, blast impulse
Pressure flame in ripple and transfer pipeline can discharge from difference detonating fusee, reduce conveyance conduit blast impulse wave pressure and impact
Intensity of wave, blast impulse is prevented to be passed to the pipeline other end.
Wherein, the diameter of difference detonating fusee is bigger than connecting tube, and guarantee has enough explosion venting areas, so as to ensure to explode
Impact involves flame and smoothly discharged from difference detonating fusee, the diameter of branch pipe and the relation and venting pressure that are connected pipe diameter,
It is relevant with actual condition, determined according to specific operating mode.
2nd, Y types elongnated building device of the present utility model is one of equipment of effective control blast scale, can be effective
Gas, dust explosion pipe explosion disaster are reduced, reduces life and property loss.Y type elongnated building devices are installed on fuel gas and dust
On conveyance conduit, when generation pipe explosion, detonation propagation to Y type elongnated building devices installation place, when blast pressure is more than device
Venting pressure value, blast impulse wave pressure and explosive flame can discharge from the Y type difference detonating fusees of device, so as to reduce pipe
Blast pressure and flame intensity in road, reduce explosive damage degree.
