Abstract
An object of the utility model is to provide a vacuum can, the technical problem of vacuum can evacuation inefficiency among the solution prior art, its structure includes: the jar body, be provided with a plurality of interfaces of bleeding on the jar body. The utility model discloses a research and develop a vacuum can, help under depressurized environment more that the efficient shortened the required time of vacuum can evacuation, further help improving vacuum pumping operation's operating efficiency.
Description
Technical field
This utility model relates to Dewar vessel technical field, is specifically related to a kind of vacuum tank.
Background technology
Dewar vessel of the prior art the most only possesses a bleed-off passage, and is provided with on passage and possesses bubble-tight check valve, to maintain the vacuum in container.Owing to being positioned at during the air of container is drawn out of under the effect of negative pressure, air can be more and more thinner, under the most same negative pressure, the rate of change being positioned at container pressure can be increasingly slower, typically requires persistently aspirate long time to reach the vacuum under technology requires.
Therefore, research and develop a vacuum tank, to overcome above-mentioned deficiency, improve the evacuation efficiency of Dewar vessel, become a kind of required.
Utility model content
To this end, the purpose of this utility model is to provide a kind of vacuum tank, solve the inefficient technical problem of vacuum tank evacuation in prior art.
To this end, this utility model provides a kind of vacuum tank, including: tank body, described tank body is provided with multiple suction interface.
According to an embodiment of the present utility model, wherein, the quantity of described suction interface is two.
According to an embodiment of the present utility model, wherein, when the volume of described tank body is axial symmetry, the suction interface on described tank body is arranged symmetrically with relative to the axis of symmetry of described tank body.
According to an embodiment of the present utility model, wherein, described suction interface includes: exhaust tube and check valve；Described tank interior is stretched in one end of described exhaust tube.
According to an embodiment of the present utility model, wherein, described exhaust tube is positioned at the part of described tank interior, and several aspirating hole is distributed on tube wall.
According to an embodiment of the present utility model, wherein, described exhaust tube is positioned at the part of described tank interior, is provided with filter screen.
This utility model, by a kind of vacuum tank of research and development, contributes to more efficient shortening the time needed for vacuum tank evacuation under subnormal ambient, is further favorably improved the working performance of vacuum pumping.
Further, this utility model is by being set to two by the quantity of suction interface, and uses the form of symmetry to arrange, when contributing to further shortening tank body evacuation operation, is positioned at the technical problem that the air of tank interior is drawn out of with shortest path.
Further, this utility model, by one end of exhaust tube is stretched into tank interior, provides strong structural support for further reducing the stroke of desirable movement when air in tank body is drawn out of.
Further, this utility model arranges several aspirating holes by being positioned at exhaust tube on the tube wall of the part of described tank interior, contributes to the pumping efficiency further promoting vacuum tank when evacuation operation.
Further, this utility model arranges filter screen by the part being positioned at tank interior at exhaust tube, provides strong technical support for prevention exhaust tube blocking.

Detailed description of the invention
Below in conjunction with Figure of description and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are merely to illustrate this utility model, but can not be used for limiting scope of the present utility model.
Embodiment 1:
Without loss of generality, as it is shown in figure 1, this utility model provides a kind of vacuum tank, including: tank body 100, described tank body is provided with multiple suction interface 101.This utility model, by a kind of vacuum tank of research and development, contributes to more efficient shortening the time needed for vacuum tank evacuation under subnormal ambient, is further favorably improved the working performance of vacuum pumping.
It should be noted that in the present embodiment, suction interface to arrange quantity unrestricted, any number of suction interface arranged on tank body for meeting further efficient evacuation operation all should fall into protection domain of the present utility model.
Preferably, in an optimal technical scheme of the present embodiment, the quantity of described suction interface is two.
Preferably, in an optimal technical scheme of the present embodiment, when the volume of described tank body is axial symmetry, the suction interface on described tank body is arranged symmetrically with relative to the axis of symmetry of described tank body.
Embodiment 2:
As in figure 2 it is shown, the present embodiment is on the basis of embodiment 1, described suction interface includes: exhaust tube 111 and check valve 121；Described tank interior is stretched in one end of described exhaust tube 111.This utility model, by one end of exhaust tube is stretched into tank interior, provides strong structural support for further reducing the stroke of desirable movement when air in tank body is drawn out of.
Further, as it is shown on figure 3, in an optimal technical scheme of the present embodiment, described exhaust tube is positioned at the part of described tank interior, on tube wall, several aspirating hole 131 is distributed.This utility model arranges several aspirating holes by being positioned at exhaust tube on the tube wall of the part of described tank interior, contributes to the pumping efficiency further promoting vacuum tank when evacuation operation.
Preferably, as shown in Figure 4, in an optimal technical scheme of the present embodiment, described exhaust tube is positioned at the part of described tank interior, is provided with filter screen 141.Owing to, in routine use, being positioned at tank interior and often depositing easily at particulate materials such as dust, this utility model arranges filter screen by the part being positioned at tank interior at exhaust tube, provides strong technical support for prevention exhaust tube blocking.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
