Abstract
The utility model discloses a kind of ball valve self-closing vacuum sample bottle, comprise bottle and lid, lid is provided with the adjustable diameter and screw adjusting push rod that swing handle, screw rod and platen are formed; Screw rod and lid are screw thread fit, have spheroid and packing seal in lid, have through hole in the middle of packing seal, and spheroid realizes conducting and closes through hole effect, and operation swing handle can drive screw rod and platen to withstand spheroid and through hole compression be closed; Tapering plug and bottleneck inwall carry out extruding tensioned fit and realize sealing; Bottle is undertaken being connected, sealing and compressing by screw thread fit with lid.The ingenious utilization of the utility model vacuumizes the automatic closedown and unlatching that realize ball valve with draught head during vacuum breaker, is conducive to sample preserves for a long time under vacuum conditions spheroid compression; The unidirectional control conducting of spheroid vacuumizes with closedown realization and maintains with vacuum, and ball valve controls to be line contact sealing and spheroid ensures location automatically, guarantees the timely closedown of vacuum breaker late gate; Design succinctly reliable, practical, have a extensive future.
Description
Technical field
The utility model relates to a kind of sample bottle, specifically refers to ball valve self-closing vacuum sample bottle.
Background technology
Sample bottle is the underlying instrument that laboratory frequently uses, be mainly used in preserving sample, existing sample bottle adopts glass or organic transparent material to make mostly, bottleneck adopts frosted or screw thread process, be conducive to observing and being hedged off from the outer world, but can not make to keep vacuum state in bottle, sample bottle more can not be made to vacuumize rear automatic-closing valve, keep vacuum state for a long time.
Some sample, the standard items that particularly some added value is higher have very high preservation requirement, and wherein an index is exactly vacuum to preserve, otherwise can decompose or go bad, and thus prior art can not meet the demands.
Utility model content
The technical problems to be solved in the utility model is exactly the deficiency existed for prior art, a kind of ball valve self-closing vacuum sample bottle is provided, also can keep vacuum state for a long time by automatic-closing valve after this sample bottle carries out vacuum pumping, preserve sample for research and production and provide support and facility.
For overcoming the deficiencies in the prior art, the utility model takes following technical scheme:
A kind of ball valve self-closing vacuum sample bottle, comprises bottle and lid, it is characterized in that: lid is provided with the adjustable diameter and screw adjusting push rod that swing handle, screw rod and platen are formed; Screw rod and lid are screw thread fit, have spheroid and packing seal in lid, have through hole in the middle of packing seal, and spheroid realizes conducting and closes through hole effect, and operation swing handle can drive screw rod and platen to withstand spheroid and through hole compression be closed; Tapering plug and bottleneck inwall carry out extruding tensioned fit and realize sealing; Bottle is undertaken being connected, sealing and compressing by screw thread fit with lid.
Being provided with positioning step in described lid prevents packing seal from deviating from.
Described bottle is provided with ring collar.
When carrying out Sample storage, screw off lid and load sample, then screwed by spiral cover, swing handle rotates micro-platen that moves back and unclamps spheroid, at this moment whole bottle is put into vacuum tank and just can carry out vacuum pumping.
Under vacuum action, because bottle internal gas pressure is greater than the outer air pressure of bottle, spheroid can automatically be opened through hole and realize vacuum pumping under differential pressure action; When vacuumizing end vacuum breaker, because bottle internal gas pressure is less than the outer air pressure of bottle, through hole automatically can be compressed closedown by spheroid under differential pressure action, and realize vacuum in bottle and maintain, swing handle slightly rotates appropriateness and platen is compressed spheroid, can realize more failure-free through hole and close.
Compared with prior art, the beneficial effects of the utility model are:
Ingenious utilization vacuumize with sample bottle during vacuum breaker inside and outside the draught head that exists, realize automatic closedown and the unlatching of ball valve, be conducive to sample and preserve for a long time under vacuum conditions; The unidirectional control conducting of spheroid vacuumizes with closedown realization and maintains with vacuum, and ball valve controls to be line contact sealing and spheroid ensures location automatically, guarantees the timely closedown of vacuum breaker late gate; Spheroid is compressed slightly and can ensure through hole more failure-free closedown, extend vacuum and hold time; Unit design is succinctly reliable, practical, is convenient to low cost and implements, have a extensive future.
Accompanying drawing explanation
Fig. 1 is part plan structural representation of the present utility model.
Fig. 2 is integral planar structural representation of the present utility model.
In figure, each label represents:
1, swing handle; 2, screw rod; 3, platen; 4, spheroid; 5, lid; 6, positioning step; 7, screw thread fit; 8, through hole; 9, packing seal; 10, tapering plug; 11, bottleneck inwall; 12, ring collar; 13, bottle.
Detailed description of the invention
Now by reference to the accompanying drawings, the utility model is illustrated further.
Ball valve self-closing vacuum sample bottle as depicted in figs. 1 and 2, comprises bottle 13 and lid 5, and lid is provided with the adjustable diameter and screw adjusting push rod that swing handle 1, screw rod 2 and platen 3 are formed; Screw rod 2 and lid are screw thread fit, have spheroid 4 and packing seal 9 in lid, have through hole 8 in the middle of packing seal 9, and spheroid 4 realizes conducting and acts on closedown through hole 8, and operation swing handle 1 can drive screw rod 2 and platen 3 to withstand spheroid 4 and through hole 8 is compressed closedown; Tapering plug 10 and bottleneck inwall 11 carry out extruding tensioned fit and realize sealing; Bottle 13 is undertaken being connected, sealing and compressing by screw thread fit 7 with lid 5.
Being provided with positioning step 6 in described lid prevents packing seal 9 from deviating from.
Described bottle 13 is provided with ring collar 12.
When carrying out Sample storage, screw off lid 5 and load sample, then screwed by spiral cover 5, swing handle 1 rotates micro-platen 3 that moves back and unclamps spheroid 4, at this moment whole bottle is put into vacuum tank and just can carry out vacuum pumping.
Under vacuum action, because bottle internal gas pressure is greater than the outer air pressure of bottle, spheroid 4 can automatically be opened through hole 8 and realize vacuum pumping under differential pressure action; When vacuumizing end vacuum breaker, because bottle internal gas pressure is less than the outer air pressure of bottle, through hole 8 automatically can be compressed closedown by spheroid 4 under differential pressure action, realizes vacuum in bottle and maintains, swing handle 1 slightly rotates appropriateness and platen 3 is compressed spheroid 4, can realize more failure-free through hole 8 and close.
Above-mentioned just preferred embodiment of the present utility model, not does any pro forma restriction to the utility model.Any those of ordinary skill in the art, when not departing from technical solutions of the utility model scope, the technology contents of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solutions of the utility model, according to the utility model technical spirit to any simple modification made for any of the above embodiments, equivalent variations and modification, all should drop in the scope of technical solutions of the utility model protection.
