Description
Technical field
The invention belongs to fire-proof and explosion-proof experiment air distributing device field, be specifically related to a kind of inflammable gas air distributing device.
Background technology
Inflammable gas is hazardous chemical common in industrial processes, and it generally adopts the mode such as closed container or pipeline to carry out accumulating.Due to the restriction in space, gas often produces rate of pressure rise sharply and higher explosion pressure after lighting a fire with air or other combustion-supporting property gas and vapor permeation under constraint condition, cause serious damage sequence.Datonation-inhibition technology is the effective means suppressed blast when exploding and front or blast generation may occurring.At present, existing datonation-inhibition technical research direction mainly comprises pressed powder explosion-suppressing material, inert gas explosion-suppressing material and water base explosion-suppressing material etc.Wherein inflammable gas or the preparation of inert gas have important effect to the progress of experiment and result.
The gas distributing system in domestic many fire-proof and explosion-proof laboratories generally mixes the formations such as unit, test flume unit, mechanical pressure gauge, data acquisition unit, computing machine primarily of gas source unit, flow controlling unit, gas.Flow controlling unit mostly adopts artificial reading to control, and what gas was mixed directly allocates test flume into from gas source unit, and more advanced then being mixed after device mixes by gas adds test flume.The shortcoming of above prior art is that labor workload is large, and number of work is many, distribution accuracy rate and success ratio low, affect greatly by peopleware, poor stability, precision is low, reaction velocity is slow, cause distribution and conventional efficient low.Most of air distributing device function singleness can only be that the experiment of same type uses; More complicated gas distributing system is then expensive, and precision preparation and accuracy have exceeded needed for experiment.
Summary of the invention
The present invention is directed to current datonation-inhibition experiment air distributing device function singleness, complicated operation loaded down with trivial details, be suitable for the technical matterss such as experiment type is limited, a kind of combustible gas air distributing device is provided, this device has the features such as cost is low, simple to operate, distribution is stable, convenient for cleaning, is applicable to polytype datonation-inhibition experiment.
Technical solution of the present invention: a kind of inflammable gas air distributing device, comprising: mixed gas tank, seal flange, accessories section; Described mixed gas tank is by the interconnective horizontal cylindrical tank of bolt, and two ends adopt seal flange sealing.Described accessories section, comprise be arranged on mixed gas tank top pressure vacuum gauge adapter, vacuum valve adapter, atmospheric valve adapter, adapter for subsequent use; The side that bottom is provided with the mixed gas tank of base for supporting 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 architecture is reasonable, powerful, easy to operate.Distribution tank, seal flange are bolted, and distribution can realize different dismounting combination flexibly, so can experimentally needed for be assembled into the air distributing device of different structure and volume.Device adopts a point platen press distribution, accurately can regulate distribution ratio, and then can enter datonation-inhibition test to the flammable mixed gas of variable concentrations level.The setting of pressure vacuum gauge both can to have measured in distribution process vacuum tightness in distribution tank, can to measure again after distribution original pressure in distribution tank.Security of the present invention is high, low cost of manufacture, can be widely used in the distribution work of dissimilar datonation-inhibition experiment, reduces the spending of experiment.
