Description
Technical field
The invention belongs to fire-proof and explosion-proof experiment air distributing device field, be specifically related to a kind of fuel gas air distributing device.
Background technology
Imflammable gas is hazardous chemical common in industrial processes, and it typically uses hermetic container or pipeline etc.
Mode carries out accumulating.Due to the restriction in space, gas under constraints with air or other combustion-supporting property gas mixed firing after
Often produce rate of pressure rise drastically and higher blast pressure, cause serious damage sequence.Datonation-inhibition technology be
Blast it may happen that front or time blast occurs to the effective means that suppresses of blast.At present, existing datonation-inhibition technical research side
To mainly including pressed powder explosion-suppressing material, noble gas explosion-suppressing material and water base explosion-suppressing material etc..Wherein fuel gas or
The preparation of noble gas has important effect to progress and the result of experiment.
The air distribution system of domestic many fire-proof and explosion-proof laboratorys is typically main by gas source unit, flow controlling unit, gas
Mix unit, test flume unit, mechanical pressure gauge, data acquisition unit, computer etc. to constitute.Flow controlling unit mostly uses people
Part work and part study number controls, and what gas was mixed direct allocates test flume into from gas source unit, more advanced then mixed device by gas and mixes
Test flume is added after conjunction.The shortcoming of above prior art is that labor workload is big, and number of work is many, distribution accuracy rate and success
Rate is low, is affected greatly by peopleware, poor stability, and precision is low, response speed is slow, causes distribution and conventional efficient low.Mostly
Number air distributing device function singleness, is only same type of experiment and uses；More complicated air distribution system is the most expensive, preparation
It is required that precision and accuracy have exceeded experiment.
Summary of the invention
The present invention is directed to current datonation-inhibition experiment air distributing device function singleness, operation complexity is loaded down with trivial details, it is limited to be suitable for experiment type
Etc. technical problem, it is provided that a kind of combustible gas air distributing device, this device have low cost, simple to operate, distribution is stable, convenient for cleaning
Etc. feature, it is adaptable to polytype datonation-inhibition experiment.
The technical solution of the present invention: a kind of fuel gas air distributing device, including: mixed gas tank, sealing flange, accessory portion
Point；Described mixed gas tank is the horizontal cylindrical tank that can be inter-connected via a bolt joint, and two ends use sealing flange to seal.Described attached
Part part, including being arranged on the pressure vacuum gauge adapter at mixed gas tank top, vacuum valve adapter, atmospheric valve adapter, standby adapter；The end
Portion is provided with the side of the mixed gas tank supporting base and is provided with gas inlet adapter, and opposite side is provided with gas outlet adapter.
Compared with prior art, the invention has the beneficial effects as follows: system structure is reasonable, powerful, easy to operate.Distribution
Tank, sealing flange are bolted, and distribution can realize different dismounting combinations flexibly, and then can be assembled into according to needed for experiment
Different structure and the air distributing device of volume.Device uses dividing potential drop method distribution, it is possible to accurately regulate distribution ratio, and then can be dense to difference
The flammable mixed gas of degree level enters datonation-inhibition test.The setting of pressure vacuum gauge both can measure during distribution true in distribution tank
Reciprocal of duty cycle, can measure again after distribution initial pressure in distribution tank.Safety of the present invention is high, and low cost of manufacture can be widely used for not
Work with the distribution of the datonation-inhibition experiment of type, reduce the spending of experiment.
