The liquefied natural gas bottle topping up automatic limit device that the utility model provides, be provided with knock out drum, after LNG Liquefied natural gas has been inflated, reach gas-liquid phase equilibrium through after a while, partial liquefaction rock gas in liquefied natural gas bottle enters into knock out drum, make LNG Liquefied natural gas inner upper end occur enough large substitute phase space, avoided producing situation about overcharging in the time filling LNG Liquefied natural gas.
Brief description of the drawings
Liquefied natural gas bottle topping up automatic limit device the first working state figure that Fig. 1 provides for the utility model embodiment;
Liquefied natural gas bottle topping up automatic limit device the second working state figure that Fig. 2 provides for the utility model embodiment;
Liquefied natural gas bottle topping up automatic limit device the 3rd working state figure that Fig. 3 provides for the utility model embodiment.
Embodiment
Referring to Fig. 1-Fig. 3, the utility model embodiment provides a kind of liquefied natural gas bottle topping up automatic limit device, comprising: storage tank, cryopump, vacuum heat-insulating hose, ready-packaged joint 1, liquefied natural gas bottle 4, one-way valve 2, spray pipeline 3 and at least one knock out drum 5 (the present embodiment adopts a knock out drum 5).Storage tank is connected with vacuum heat-insulating pipe by cryopump, and vacuum heat-insulating pipe is connected with ready-packaged joint 1, and ready-packaged joint 1 is connected with spray pipeline 3 by one-way valve 2.Spray pipeline 3 is arranged on the inner upper end of liquefied natural gas bottle 4, and liquefied natural gas bottle 4 is arranged on vehicle.Knock out drum 5 is arranged on liquefied natural gas bottle 4 inside, and the bottom of knock out drum 5 offers through hole, and the aperture of through hole is 1.5～2.5mm (in the present embodiment, the aperture of through hole adopts 2mm).Referring to Fig. 1-Fig. 3, in the present embodiment, knock out drum 5 is fixed on the neutral position between the upper and lower end in liquefied natural gas bottle 4, and knock out drum 5 is fixed on the sidewall of liquefied natural gas bottle 4.
The working principle of the liquefied natural gas bottle 4 topping up automatic limit devices that the utility model embodiment provides is as follows: referring to Fig. 1-Fig. 3, LNG Liquefied natural gas is exported from storage tank, through cryopump, vacuum heat-insulating hose, ready-packaged joint 1, one-way valve 2 is transported to liquefied natural gas bottle 4 inside, be arranged on the spray pipeline 3 of liquefied natural gas bottle 4 inner tops, make LNG Liquefied natural gas with vaporific form ejection, realize the steam in liquefied natural gas bottle 4 is carried out to condensation, step-down and LNG Liquefied natural gas fill fast, when liquid fills, the through hole that liquid in bottle can arrange by knock out drum 5 bottoms slowly enters in knock out drum 5.Referring to Fig. 2, LNG Liquefied natural gas arrives after liquefied natural gas bottle 4 inner tip, the outer LNG Liquefied natural gas of filling up of knock out drum 5, knock out drum 5 enters slowly the interior LNG Liquefied natural gas of liquefied natural gas bottle 4 compared with conference because of its internal gas pressure, now spray pipeline 3 continues topping up and can make pressure in liquefied natural gas bottle 4 be rapidly increased to the maximum delivery pressure of cryopump, make cryopump stop being filled with LNG Liquefied natural gas, now knock out drum 5 inner upper end leave certain expansion space.Referring to Fig. 3, stop being filled with after LNG Liquefied natural gas a period of time, in liquefied natural gas bottle 4 and knock out drum 5, reach gas-liquid phase equilibrium, partial liquefaction rock gas in liquefied natural gas bottle 4 enters knock out drum 5 by the through hole of knock out drum bottom, make liquefied natural gas bottle 4 inner upper end occur enough large substitute phase space, avoided producing situation about overcharging in the time filling LNG Liquefied natural gas.
Referring to Fig. 1-Fig. 3, the liquefied natural gas bottle 4 topping up automatic limit devices that the utility model embodiment provides, be provided with knock out drum 5, after LNG Liquefied natural gas has been inflated, reach gas-liquid phase equilibrium through after a while, partial liquefaction rock gas in liquefied natural gas bottle 4 enters into knock out drum 5, makes LNG Liquefied natural gas inner upper end occur enough large substitute phase space, has avoided producing situation about overcharging in the time filling LNG Liquefied natural gas.In addition, the liquefied natural gas bottle 4 topping up automatic limit devices that the utility model embodiment provides are simple in structure, are convenient in the extensive use of the field such as natural gas transportation, storage.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
