Abstract
The utility model provides a vacuum store tank, which is mainly and technically characterized in that the vacuum store tank comprises a tank body and a tank cover which is tightly connected with an upper opening of the tank body with screw threads by a sealing ring, wherein, the middle part of the tank cover is provided with a plurality of through holes along a radial direction. A rubber extraction valve with an elastic gap joint and a fixed ring are orderly inlaid into a dishing point in the middle part of the tank cover. The outer edge in the radial direction of a vacuum protective press plate is tightly connected with an upper opening of the dishing point in the middle part of the tank cover by screw threads. The middle position along the radial direction of the rubber extraction valve is tightly pressed on the tank cover by a lower opening of the vacuum protective press plate. The vacuum store tank has a very good environment for vacuum object store.
Description
The utility model relates to the container that is used for storing material, particularly a kind of vacuum storing tank.
Some material such as tealeaves etc. need could the long period keep its original color characteristic under the condition of drying, anoxybiotic, lucifuge, low temperature.Commercially available vacuum tea jar has the member that vacuumizes, therefore the storage substance environment that possesses certain drying, anoxybiotic and lucifuge, but the rubber extraction valve on the above-mentioned vacuum storing tank cover is rubber-like slit structure, described rubber extraction valve is subjected to the influence of ambient temperature or outer variation easily and is not closed completely, cause air inlet in the storing tank, As time goes on, a jar interior negative pressure of vacuum environment will be destroyed.Through test, after above-mentioned vacuum storing tank vacuumized 120 hours, anoxybiotic, dry environment in jar be subjected to destruction to a certain degree, even the vacuum storing tank places under the cryogenic conditions, its quality of storing tealeaves is also undesirable.Time is long slightly, is stored in jar interior tealeaves and just can not keeps its original color characteristic.
The purpose of this utility model will provide a kind of improved vacuum storing tank exactly.This storing tank can keep having anoxybiotic in the jar long period, dry vacuum is store substance environment.
Task of the present utility model is finished as follows.
A kind of vacuum storing tank has tank body, seal ring, cover, its characteristics be described cover vertically section form be
Shape, and by seal ring and tank body is suitable for reading connects airtight with screw thread, described cover radially middle part is provided with several through holes, the recess at described cover middle part embeds the rubber extraction valve and the mounting ring of band elasticity slit joint in proper order, the screw thread suitable for reading at the radially outer edge of fidelity pneumatics plate and described cover medial recess place connects airtight, and the end opening of described fidelity pneumatics plate is pressed on rubber extraction valve middle part radially on the cover.
The upper bottom surface of the utility model vacuum storing tank fidelity pneumatics plate can be provided with swing handle.
Swing handle on the utility model vacuum storing tank fidelity pneumatics plate can be criss-cross.
The cover of the utility model vacuum storing tank is by seal ring and tank body is suitable for reading connects airtight, mounting ring is positioned at the rubber extraction valve recess at cover middle part, therefore when the joint in rubber extraction valve band elasticity slit and vacuum pump connect airtight, air in the tank body can be on cover through hole and elasticity slit and being drawn out of, make the storage substance environment that forms negative pressure of vacuum in the tank body, again because the radially outer edge of fidelity pneumatics plate and suitable for reading the connecting airtight at cover medial recess place with screw thread, fidelity pneumatics plate end opening is pressed on rubber extraction valve middle part radially on the cover, so the outer air of tank body is difficult to elasticity slit, footpath and through hole enters in the tank body.Through test, newly picked and processed tea leaves are stored in the utility model vacuum storing tank, and seasoning was taken out after three months in refrigerator, the color of tealeaves all keeps original quality, this shows that fidelity sky of the present utility model is very capable, compared to the prior art, have better drying, anoxybiotic vacuum storage substance environment.
Below with reference to accompanying drawing structure of the present utility model is described in further detail.

Figure 12 is along the organigram of analysing and observe of F-F line among Figure 11.
Consult Fig. 1-Figure 12, the utility model comprises tank body 1, and tank body 1 can be molded with metal paattern, and the outside thread that is provided with suitable for reading, tank body possess lucifuge storage thing condition.Be provided with in the flange of cover 3 with tank body on the negative thread that is complementary of interface external thread, cover 3 can connect airtight on tank body 1 by seal ring 2.Cover 3 medial recess, and radially the middle part is provided with some through holes 4, cover medial recess place embeds the rubber extraction valve 6 and the mounting ring 7 of band elasticity slit joint 5 in proper order, and described mounting ring can make the rubber extraction valve be fixed in the cover medial recess.Suitable for reading the connecting airtight at the radially outer edge of fidelity pneumatics plate 8 and cover medial recess place with screw thread, the end opening of fidelity pneumatics plate then is pressed on the rubber extraction valve on the cover 3, and the through hole 4 on the cover 3 is tightly cut off with elasticity slit and getting in touch all of the external world on the rubber extraction valve at this moment.The top of fidelity pneumatics plate 8 can be provided with swing handle 9, and swing handle 9 can be criss-cross.
When the utility model vacuum storing tank uses, the material (as tealeaves etc.) of in tank body, packing into earlier, the cover flange is embedded in behind the seal ring with screw thread and tank body is suitable for reading connects airtight, recess at the cover middle part embeds rubber extraction valve and mounting ring in proper order, the joint and the vacuum pump in band elasticity slit on the rubber extraction valve are connected airtight, air in the tank body can be taken away by vacuum pump through the elasticity slit on through hole on the cover and the rubber extraction valve, screw fidelity pneumatics plate then, can form vacuum storage substance environment in the tank body.
