Abstract
The utility model discloses a Dewar bottle filling device which comprises an output pipeline, split charging pipelines, low temperature valves and flexible metal tubes. The output pipeline and the split charging pipelines are respectively connected with low temperature valves, one end of the output pipeline is connected with a nitrogen tank, the other end of the output pipeline is connected with the split charging pipelines, one ends of the split charging pipelines are connected with the flexible metal tubes, and the other ends of the flexible metal tubes are Dewar filling openings. Due to the methods, the Dewar bottle filling device is capable of saving energy, reducing consumption, improving filling efficiency, and prolonging service life. Nitrogen vent loss is reduced through high pressure filling, and the Dewar bottle can be directly filled through the connection between the flexible metal tubes and the Dewar bottle, and therefore the whole process is energy-saving and cost-reducing, and the filling is faster and more convenient. The low temperature valves play a safety protection role in the whole filling process, and therefore accidents caused by overhigh pressure of the system are prevented from happening.
Description
Technical field
The utility model relates to the charging device field of cryogenic liquide gas, particularly relate to a kind of Dewar vessel charging device.
Background technique
At present, Dewar vessel has been widely used in the relevant fields such as scientific research, health care, oil drilling because thermal insulation property is good, fills quantity also in continuous increase for Dewar vessel.But generally the heat owing to absorbing environmental, metallic hose etc. causes liquid nitrogen vaporization in filling process, cause the tank internal pressure to raise, can't fill smoothly, usually need release emptying, guarantee fills unimpeded, this Dewar filling process relatively slowly and loss large, so too high, the poor stability of cost.
The model utility content
The technical problem that the utility model mainly solves provides a kind of Dewar vessel charging device, can save energy and reduce the cost, improve and fill efficient, increase working life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of Dewar vessel charging device is provided, comprise output pipeline, packing pipeline, low temperature valve and metallic hose, be connected with respectively low temperature valve on described output pipeline and the packing pipeline, one end of described output pipeline connects nitrogen pot, its the other end connects the packing pipeline, an end connection metal flexible pipe of described packing pipeline, and the other end of described metallic hose is that Dewar fills mouth.
The beneficial effects of the utility model are: the utility model has reduced nitrogen emptying loss by High-pressure charging, and can connect Dewar vessel by metallic hose and directly fill Dewar, whole process energy conservation consumption reduction, fill faster more convenient; In whole filling process, play the safety protection effect by low temperature valve, thereby the assurance system does not have an accident because of overpressure.
Description of drawings
Fig. 1 is the perspective view of the utility model Dewar vessel charging device;
The mark of each parts is as follows in the accompanying drawing: 1, output pipeline 2, packing pipeline 3, low temperature valve 4, metallic hose 5, nitrogen pot.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model is embodiment comprise: output pipeline 1, packing pipeline 2, low temperature valve 3 and metallic hose 4, be connected with respectively low temperature valve on described output pipeline 1 and the packing pipeline 2, one end of 3 described output pipelines 1 connects nitrogen pot 5, its the other end connects packing pipeline 2, one end connection metal flexible pipe 4 of described packing pipeline 2, the other end of described metallic hose 4 is that Dewar fills mouth.
The utility model has reduced nitrogen emptying loss by High-pressure charging, and can connect Dewar vessel by metallic hose 4 and directly fill Dewar, whole process energy conservation consumption reduction, fill faster more convenient; In whole filling process, play the safety protection effect by low temperature valve 3, thereby the assurance system does not have an accident because of overpressure.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
