Justice.There are the following problems for traditional explosion testing device：
（1）The safety of completely enclosed device and sex chromosome mosaicism easy to operate.If device is completely enclosed, fuel gas is complete
After there is blast in totally enclosed container, blast pressure is about 7-10 atmospheric pressure, needs the resistance to pressure of device very good, this
Sample, first resistance to pressure apparatus cost are high, and test is dangerous big.
（2）The test platform of open environment is little due to blast pressure, and accuracy is affected greatly by external interference.Open wide completely
In environment, flammable gas explosion superpressure is less, general small-scale test, and peak overpressure value is with regard to several kPa, such as 2-3kPa.But
It is the position for being difficult that cloth occurs in peak overpressure of layouting of general sensor, many positions only have hundreds of Pa even tens Pa.This
Sample, as test pressure absolute value is low, and external environment such as wind speed change, accidentalia, test-meter precision itself are brought
Error, so may can bring the impact that can not ignore to test so that press down in water smoke close to this blast pressure value
In quick-fried test, effect is difficult to com-parison and analysis.
The content of the invention
The purpose of this utility model, is to solve the problems, such as the datonation-inhibition test of fuel gas, it is proposed that a kind of to be used for water smoke
The safety explosive test test device of effectiveness of explosion suppression.The device can be on the premise of manual control safety, by progressively
Increase the degree of closure of the device explosion proof box blast pressure value interval to obtain an about 10kPa-20kPa.By this
Device, can be by changing the parameters such as injection intensity, injection density, water smoke particle diameter and the spray regime of water smoke, and research is different
Effectiveness of explosion suppression under water smoke state, is found for the optimal explosion-suppressing method of different types of fuel gas.
For achieving the above object, the technical scheme for being adopted is this utility model：A kind of peace for water smoke effectiveness of explosion suppression
Holotype explosive test test device, it is characterised in that：By air supply system, the adjustable explosive test case of aperture, pressure data collection
System and water spray injector system composition；

Force transducer connects, and the incendiary source controller is coordinated with incendiary source remote control.The beneficial effects of the utility model and advantage are：Should
Device avoids traditional, completely enclosed assay device cost height, blast pressure causes greatly dangerous big, complex operation etc. to be asked
Topic.Using the device, before formal datonation-inhibition test, by casing by being stepped up the degree of closure of the device explosion proof box
The blast pressure value interval to obtain an about 10kPa-20kPa, after blast pressure reaches this pressure range, due to wind speed
The error that the extraneous factors such as change, accidentalia, test-meter precision itself are brought can typically be far below this pressure value, so as to
Test error becomes to ignore.In addition, relative to completely enclosed gas burst, this blast pressure value is less, test peace
It is easier to entirely ensure.
In a word by the device, can be by the injection intensity of change water smoke, injection density, water smoke particle diameter and injection side
The parameters such as formula, the effectiveness of explosion suppression under the different water smoke states of research, are found for the optimal datonation-inhibition side of different types of fuel gas
