Embodiment
It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model
Example is applied to elaborate to the utility model.
Embodiment of the present utility model discloses a kind of LNG storage tank gas leakage preventing device, as illustrated, it includes collecting
Pipe 1, cooling gas check valve 2, shell 3, siren 4, control system 5, magnetic valve 6, storage tank 7, air pressure inductor 8, inner casing 9 and vacuum
Pump 10,
The outside of storage tank 7 is provided with inner casing 9, and the inner homogeneous of inner casing 9 is distributed with four air pressure inductors 8；Outside inner casing 9
Side is provided with shell 3, the electromagnetism symmetrical with center line of the one end provided with two relative storage tanks 7 of the intersection of shell 3 of inner casing 9
Valve 6；The inner homogeneous of shell 3 is distributed with four air pressure inductors 8；The outside of the relative other end provided with magnetic valve 6 of shell 3
Provided with vavuum pump 10, the outside of vavuum pump 10 is connected with collecting pipe 1, and cooling gas check valve 2 is provided with the junction of shell 3；Outside
The top of shell 3 is fixed with siren 4 and control system 5.
In the present embodiment, PLC is provided with control system 5.
It is vacuum state in the present embodiment, in shell 3 and inner casing 9.
Operation principle of the present utility model：
The air pressure inductor 8 in air pressure inductor 8 and shell 3 in inner casing 9 passes data to control system 5 simultaneously.
If gas leakage occurs for storage tank 7, gas is entered in inner casing 9, the data that the air pressure inductor 8 in inner casing 9 is transmitted
It is larger.If crackle occurs in shell 3, enter outside air, then the data that the air pressure inductor 8 of shell 3 is transmitted are larger.
Both sides data are judged by control system 5, you can learn current gas leak condition.Once it is determined that there is gas
Reveal, then opens solenoid valve 6, gas is extracted out and is sent to through collecting pipe 1 in specified containers by vavuum pump 10, while passing through siren 4
Carry out alarm.
The utility model is described in detail above by embodiment, but the content is only of the present utility model shows
Example property embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.Protection domain of the present utility model is by right
Claim is limited.It is all to utilize technical scheme described in the utility model, or those skilled in the art is in the utility model technology
Under the inspiration of scheme, in essence of the present utility model and protection domain, design similar technical scheme and reach above-mentioned skill
Art effect, or the equivalent change made to application range and improvement etc., it all should still belong to patent of the present utility model and contain
Within lid protection domain.
