Abstract
The invention discloses a ball valve self-closed vacuum sample bottle which comprises a bottle body and a cover body. The cover body is provided with a spiral adjusting ejector rod composed of a rotating handle, a screw and a pressing disc, the screw and the cover body are in threaded fit, a ball body and a sealing pad are arranged in the cover body, a through hole is formed in middle of the sealing pad, the ball body plays a role in opening and closing the through hole, the screw and the pressing disc can be driven to be abutted against the ball body to compress and close the through hole by operating the rotating handle, a tapered plug and the inner wall of a bottle opening are in extrusion and tension fit to realize sealing, and the bottle body and the cover body are in threaded fit for connection, sealing and compression. Automatic closing and opening of the ball valve is realized by ingeniously utilizing air pressure difference during vacuumizing and vacuum breaking, and long-time storage of samples in a vacuum state is facilitated by compressing the ball body; the ball body controls opening and closing in a one-way manner to realize vacuumizing and vacuum maintaining, control of the ball valve is realized through linear contact sealing, positioning of the ball body is guaranteed automatically, and timely closing of the valve after vacuum breaking is guaranteed. The ball valve self-closed vacuum sample bottle is simple and reliable in design, high in practicability and wide in prospect.
Description
Technical field
The present invention relates to a kind of sample bottle, specifically refer 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.
Summary of the invention
The technical problem to be solved in the present invention 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 present invention 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, beneficial effect of the present invention is:
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.

Detailed description of the invention
[0027] now by reference to the accompanying drawings, the present invention 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 invention, not does any pro forma restriction to the present invention.Any those of ordinary skill in the art, when not departing from technical solution of the present invention scope, can utilize the technology contents of above-mentioned announcement to make many possible variations and modification to technical solution of the present invention, or being revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to the technology of the present invention essence to any simple modification made for any of the above embodiments, equivalent variations and modification, all should drop in the scope of technical solution of the present invention protection.
