The utility model provides a training analogue means that liquefied gas storage tank is kidney-yang, including spherical tank body, higher level's combustor, jar wall combustor, subordinate's combustor, fog generator, some firearm, cooling spray thrower, feeding house steward and control cabinet, higher level's combustor, subordinate's combustor and a jar wall combustor are controlled by the control cabinet respectively, higher level's combustor sets up respectively in spherical tank body tank deck and tank bottoms with subordinate's combustor, the jar wall department of closing on the utmost point in the spherical tank body is installed to jar wall combustor, the feeding house steward divide into the three routes through the feed valve, set out on a journey through higher level's combustor control valve after higher level's combustor pipeline is continuous with higher level's combustor, the middle way is through jar wall combustor control valve after a jar wall combustor pipeline is continuous with jar wall combustor, down subordinate's combustor control valve is crossed after subordinate's combustor pipeline links to each other with the subordinate combustor to the sweetgum fruit. The device can simulate all kinds of detonation scenes of liquefied gas storage tank, has the fidelity height, and the flexibility is strong, the advantage of cleanness environmental protection.
