Abstract
The utility model belongs to the anti-overflow technical field of liquid, is specifically related to a kind of for the anti-overflow device for storing liquid in liquid metal atomic source.The utility model comprises housing, and described case top is provided with jet pipe, is vertically provided with anti-overflow rod in described housing, and described anti-overflow rod is evenly arranged on the base plate of housing.Compare traditional liquid metal is filled be bound by bulk, the method had in the porous medium in micron order aperture, the utility model adopts the structure evenly arranging anti-overflow rod in housing, is bound by between anti-overflow rod by liquid metal, has saved space, increase filling amount, reduce mission payload amount; Avoid the large area between liquid metal with porous medium to greatest extent simultaneously, contact for a long time, ensure that the quality of boil-off gas line, effectively improve reliability and life-span that affiliated components and parts work in ground or space microgravity environment.
Description
Technical field
The utility model belongs to the anti-overflow technical field of liquid, is specifically related to a kind of for the anti-overflow device for storing liquid in liquid metal atomic source.
Background technology
For overflowing the liquid metal of device for storing liquid in liquid source of metal atoms, its high thermal conductivity, the Wuli-Shili-Renli system approach such as strong electric conductivity and strong metal activity can have a strong impact on other components and parts serviceability and life-spans, the consequence of even damaging property time serious; This situation obviously must prevent, especially for the scientific instrument such as measurement, detection of the various high, precision and frontiers worked under space microgravity environment, as mass spectrometer, atomic interferometer, atomic clock etc.; General, realize anti-overflow object by the porous medium that liquid metal is filled in bulk, but the evaporator obtained in this way is in order to ensure liquid supply rate, its quality and volume are very large, objectively add mission payload.More importantly, the venting rate due to bulk porous media material is high and be difficult to deimpurity feature, greatly can reduce the chemical purity of operating fluid when it infiltrates in operating fluid for a long time, thus has influence on reliability and the work life of instrument.
Utility model content
The purpose of this utility model provides a kind of device for storing liquid that can prevent liquid metal from overflowing for prior art Problems existing.
A kind of anti-overflow device for storing liquid, comprise housing, described case top is provided with jet pipe, is vertically provided with anti-overflow rod in described housing, and described anti-overflow rod is evenly arranged on the base plate of housing;
Described anti-overflow rod is cylindrical barred body, is provided with cavity, is filled with porous medium in described cavity in the barred body of described anti-overflow rod;
The porous medium of filling in described cavity is organic foam, foam metal or wire gauze;
The surface of described anti-overflow rod has uniform rough surface;
Porous medium is filled with in described jet pipe;
The porous medium of filling in described jet pipe is foam metal or wire gauze.
The utility model has following beneficial effect:
Compare traditional liquid metal is filled be bound by bulk, the method had in the porous medium in micron order aperture, the utility model adopts the structure evenly arranging anti-overflow rod in device for storing liquid, liquid metal is bound by between anti-overflow rod, save space, increase filling amount, reduce mission payload amount; Avoid the large area between liquid metal with porous medium to greatest extent simultaneously, contact for a long time, ensure that the quality of boil-off gas line, effectively improve reliability and life-span that affiliated components and parts work in ground or space microgravity environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be Figure 1A-A to schematic diagram.
Detailed description of the invention
A kind of anti-overflow device for storing liquid, comprise housing 1, described housing 1 top is provided with jet pipe 2, is vertically provided with anti-overflow excellent 3 in described housing 1, and described anti-overflow excellent 3 are evenly arranged on the base plate of housing 1; Described anti-overflow excellent 3 is cylindrical barred body, is provided with cavity 4, is filled with porous medium in described cavity in the described anti-overflow barred body of excellent 3, and the porous medium of filling in described cavity 4 is organic foam, foam metal or wire gauze; The described anti-overflow surface of excellent 3 has uniform rough surface; Be filled with porous medium in described jet pipe 2, the porous medium of filling in described jet pipe 2 is foam metal or wire gauze.
During use, liquid metal is deposited in device for storing liquid housing 1 of the present utility model, liquid metal is bound by between anti-overflow excellent 3, and the be heated gas that liquid metal gasified produce of housing 1 is discharged by porous medium in jet pipe 2 and formed stable, special quality metallic atom line; Due to anti-overflow excellent 3 inner porous mediums of filling, effectively can play the effect of inhaling ripple noise reduction, the anti-overflow outside face of excellent 3 has uniform rough surface, to liquid 2, there is good adhesiveness, adhesive attraction between further strengthening liquid and anti-overflow excellent 3, when evaporator is in ground or space microgravity environment, if when the external world rocks or vibrates generation, anti-overflow excellent 3 can prevent liquid level because rocking or vibrating and unstability, form isolated blob or mighty torrent; The porous medium of filling in jet pipe 2 has the feature of augmentation of heat transfer, mass transfer, little to the durchgriff of liquid 2, increase the resistance that liquid passes through, once there be drop to be formed in evaporation bubble, when passing through the porous medium in jet pipe 2 when drop, can be adhered thereto by force, and under the effect of hot-fluid, flash to gas rapidly.
