Technical field
The present invention relates to vacuumizing and toward the device of inflated with nitrogen in case, belonging to vacuumizing and the changeover mechanism of inflated with nitrogen of sealed packet vanning on a kind of hermetically sealed packing chest.
Background technology
At present, at the design field of hermetically sealed packing chest, to the using function of packing chest, and the requirement of the storage environment of product in packing chest is more and more higher.Some product requirement is first taken out the air in case, in case, is then filled with the nitrogen of certain pressure, its objective is and shield to product in case, to extend the service life of product after loading sealed packet vanning.Vacuumizing of existing sealed packet vanning is arranged on casing respectively with nitrogen charging device, there is sealing effectiveness difference, the problem of the loaded down with trivial details and sealing arrangement complexity of operating process.
Summary of the invention
The invention provides the vanning of a kind of sealed packet to vacuumize and nitrogen charging device, solve vacuumizing of existing sealed packet vanning and to there is complex structure and the loaded down with trivial details technical matters of operating process with nitrogen charging device.
The present invention solves above technical matters by the following technical programs:
A kind of sealed packet vanning vacuumizes and nitrogen charging device, comprise the packaging casing of sealing, packaging casing is fixedly installed and vacuumizes valve body, vacuumizing in valve body the valve body cavity of resorption and valve body epicoele that are provided with connection, annular boss is provided with between valve body cavity of resorption and valve body epicoele, the top port place of valve body epicoele is provided with negative thread, the chamber wall of valve body cavity of resorption is provided with the air extractor vent be communicated with in case of casing with sealed packet, battledore is provided with in valve body cavity of resorption, stage clip is provided with between the bottom face and the bottom surface, chamber of valve body cavity of resorption of battledore, the top end face of battledore is provided with packing seal, packing seal is crimped on the top end face of battledore by packing seal impacted bolt, the negative thread that the outside thread of vacuum-pumping tube end and the top port place of valve body epicoele are arranged is screwed together, the top of vacuum-pumping tube is provided with top pressure head, end and the packing seal impacted bolt movable top of top pressure head are connected together, top pressure head is provided with the air inlet/outlet of the tube chamber being communicated with valve body epicoele and vacuum-pumping tube.
The bottom of packing seal impacted bolt is through cross-under after battledore in the upper end hole of stage clip.
It is simple that the present invention has structure, easy to operate and feature efficiently, and what a set of mechanism can realize that sealed packet cases simultaneously vacuumizes and inflated with nitrogen function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of sealed packet vanning vacuumizes and nitrogen charging device, comprise the packaging casing 1 of sealing, packaging casing 1 is fixedly installed and vacuumizes valve body 2, vacuumizing the valve body cavity of resorption 3 and valve body epicoele 9 that are provided with connection in valve body 2, annular boss 14 is provided with between valve body cavity of resorption 3 and valve body epicoele 9, the top port place of valve body epicoele 9 is provided with negative thread 11, the chamber wall of valve body cavity of resorption 3 is provided with the air extractor vent 4 be communicated with in case of casing with sealed packet, battledore 5 is provided with in valve body cavity of resorption 3, stage clip 6 is provided with between the bottom face and the bottom surface, chamber of valve body cavity of resorption 3 of battledore 5, the top end face of battledore 5 is provided with packing seal 7, packing seal 7 is crimped on the top end face of battledore 5 by packing seal impacted bolt 8, the negative thread 11 that the outside thread of vacuum-pumping tube 10 end and the top port place of valve body epicoele 9 are arranged is screwed together, top pressure head 12 is provided with on the top of vacuum-pumping tube 10, end and packing seal impacted bolt 8 movable top of top pressure head 12 are connected together, top pressure head 12 is provided with the air inlet/outlet 13 of the tube chamber being communicated with valve body epicoele 9 and vacuum-pumping tube 10.
The bottom of packing seal impacted bolt 8 is through cross-under after battledore 5 in the upper end hole of stage clip 6.
When vacuumizing, the negative thread 11 outside thread of the end of vacuum-pumping tube 10 and the top port place of valve body epicoele 9 vacuumizing valve body 2 arranged is screwed together, in the process of being spirally connected, along with the decline of the end of vacuum-pumping tube 10, battledore 5 is pushed away downwards by packing seal impacted bolt 8 by the top pressure head 12 of the end of vacuum-pumping tube 10, along with the decline of battledore 5, what the chamber wall of valve body cavity of resorption 3 was arranged is opened with the sealed packet air extractor vent 4 be communicated with in case of casing, the gas of box house is successively by air extractor vent 4, valve body cavity of resorption 3, valve body epicoele 9, the air inlet/outlet 13 of the tube chamber of vacuum-pumping tube 10 is communicated with vacuum pumping pump with the tube chamber of vacuum-pumping tube 10, realize the operation vacuumized in case.After having vacuumized, in case, nitrogen is filled with by the tube chamber of vacuum-pumping tube 10, when rushing after nitrogen terminates, contrarotation vacuum-pumping tube 10, along with the rising of the end of vacuum-pumping tube 10, the top pressure head 12 of the end of vacuum-pumping tube 10 is removed and is pressed the top of packing seal impacted bolt 8, at this moment battledore 5 upwards raises by battledore 5 under the effect of stage clip 6, along with the lifting of battledore 5, air extractor vent 4 is closed by battledore 5 gradually, realize airtight to institute's inflated with nitrogen in case, battledore 5 rises to the packing seal 7 on it always and the annular boss 14 that arranges between valve body cavity of resorption 3 and valve body epicoele 9 pushes up force together, the elastic force of stage clip 6 passes through packing seal 7 top lift upwards, valve body cavity of resorption 3 and valve body epicoele 9 are tightly sealed, achieve the secondary seal to nitrogen in casing.
