Object of the present invention can also be realized further by following technical measures.
The filling apparatus of aforesaid a kind of LNG, the material of steel pipe is the wherein a kind of of 304L or 316L.
The filling apparatus of aforesaid a kind of LNG, out splice going splice is inipple male end, and input adapter is the inipple female end matched with out splice going splice.
The filling apparatus of aforesaid a kind of LNG, input adapter is inipple male end, and out splice going splice is the inipple female end matched with input adapter.
The filling apparatus of aforesaid a kind of LNG, air hose is provided with a Pull breaking ualve.
The present invention forms a closed-loop system by LNG output system and LNG input system, the present invention is suspended on ship taffrail or topside bulwark plating, out splice going splice is connected with input adapter, start cryopump to annotate LNG to power ship, easy to operate, pipeline of the present invention is connected with filling tank and fuel pot by flange, good seal performance, and guarantee can not be revealed; When LNG occurs to leak, Emergeny Cutoff Valves one and Emergeny Cutoff Valves two can be cut off respectively, the filling of LNG can be cut off, safe and reliable; When the large operation of wind or water surface wave cause pipeline to rupture, Pull breaking ualve is thrown off automatically, cuts off charging line, Leakage prevention, safe and reliable; When after the too much LNG that annotates to power ship, LNG flows into filling tank by the flexible pipe that goes back, and prevents the internal pressure of unnecessary LNG increasing fuel tank; The present invention annotates that efficiency is high, compact structure reusable, cost-saving; The present invention not only can be used for LNG filling ship, and also can be used for LNG aerating landing stage, using scope is wide.
Advantage and disadvantage of the present invention, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is layout schematic diagram of the present invention;
Fig. 2 is systematic schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the present invention includes LNG output system 1, LNG input system 2, LNG output system 1 be arranged on filling ship 3 on, LNG input system 2 is arranged on power ship 4, and LNG output system 1 is flexibly connected with LNG input system 2.
As shown in Figure 2, LNG output system 1 comprises filling tank 11, cryopump 12, controller 13, Pull breaking ualve 16, out splice going splice 17, Emergeny Cutoff Valves 1; Filling tank 11 is fixedly installed in the cabin of filling ship 3, the shell of filling tank 11 is provided with return-air flange 1, fills flange 1; The input end of cryopump 12 by steel pipe with fill flange 1 and be fixedly connected with, the output terminal of cryopump 12 is connected with one end of Emergeny Cutoff Valves 1, and the other end of Emergeny Cutoff Valves 1 is connected with out splice going splice 17 by air hose 14; Air hose 14 is provided with a Pull breaking ualve 16; Controller 13 is connected with cryopump 12; The material of steel pipe is 304L or 316L.
