Description
Technical field
The utility model relates to a kind of flammable gas explosion experimental provision, especially a kind of can calibration tape constraint pressure relief opening restricted clearance in flammable gas explosion disaster distribution experimental provision.
Background technology
In recent years, along with the widespread use of the inflammable gas such as China's natural gas, biogas in commercial production and resident living, under numerous constraint condition such as industrial premises, residential building, combustible gas leakage explosion accident occurrence frequency constantly rises, and causes serious casualties, property loss and severe social negative effect.Under constraint condition, flammable gas explosion accident not only causes direct disaster to human body and local, accident room key member, also very easily brings out the continuous collapse of monolithic architecture structure, the complicacy of aggravation explosion disaster and seriousness.
In this type of explosion accident, the effect that the structures such as door, window, floor, body of wall are subject to explosion wave destroys, lost efficacy, and is presented as the destruction pressure release of restrained boundary.This destruction pressure leak process will make blast process undergo mutation, thus affect the evolutionary process of follow-up accident.But, this constraint pressure relief is still unintelligible at present to the affecting laws of flammable gas explosion process, the existing correlative study for flammable gas explosion disaster in room and gained achievement, conclusion ignores this impact that constraint pressure relief causes, particularly the restricted clearance of band Constrained pressure relief is reduced to complete confined space and maybe constraint pressure relief is reduced to the free discharge border opened wide completely by the existing experimental provision for the test of flammable gas explosion disaster both at home and abroad, this is obviously difficult to capture the actual disaster feature that flammable gas explosion under constraint pressure release condition produces, hamper the accurate forecast of this type of explosion accident and effective prevention and control.
Summary of the invention
The deficiency of constraint pressure release effect is ignored in order to make up existing flammable gas explosion disaster experimental provision, the utility model provides a kind of flammable gas explosion disaster experimental provision retrained under pressure release condition, this device can effectively provide constraint pressure relief, and the key parameter of constraint pressure relief can be changed, be applied to, in the experiment of flammable gas explosion disaster, explosion disaster feature can be reflected truly.
The utility model solves the technical scheme that its technical matters adopts: flammable gas explosion disaster experimental provision under a kind of constraint pressure release condition, comprise blast cavity, frangible material flat board and fixed flat planar, one side of described blast cavity is provided with an opening, described side is plane, the edge of described opening is provided with groove, described frangible material flat board embeds in described groove, the dull and stereotyped arranged outside of described frangible material has described fixed flat planar, described fixed flat planar removably sealed by bolt be fixed on described blast cavity described side on, thus described frangible material plate seal is fixed in described groove, described fixed flat planar is provided with a pressure relief opening, its area is less than the area of described opening, the area of described fixed flat planar is greater than the area of described opening, be less than or equal to the area of described side, described blast cavity is provided with air intake opening, portfire fixed port and sensor fixed port, described air intake opening is used for being provided for producing the inflammable gas of blast and the combination gas of air to described blast inside cavity, described portfire fixed port is used for fixedly making described combination gas produce the portfire of blast, described sensor fixed port is used for the sensor of parameter in fixation measuring blast process.
Preferably, described blast cavity is cube structure.
Preferably, described opening, described pressure relief opening and described fixed flat planar are square.
Preferably, the material of described blast cavity is steel.
