The bottom of sealing gasket impacted bolt is through cross-under after plunger piston 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 internal thread 11, the chamber wall of valve body cavity of resorption 3 is provided with the passage 4 be communicated with in case of casing with sealed packet, plunger piston 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 plunger piston 5, the top end face of plunger piston 5 is provided with sealing gasket 7, sealing gasket 7 is crimped on the top end face of plunger piston 5 by sealing gasket impacted bolt 8, the internal thread 11 that the external screw 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 sealing gasket 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 sealing gasket impacted bolt 8 is through cross-under after plunger piston 5 in the upper end hole of stage clip 6.
When vacuumizing, the internal thread 11 external screw 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, plunger piston 5 is pushed away downwards by sealing gasket impacted bolt 8 by the top pressure head 12 of the end of vacuum-pumping tube 10, along with the decline of plunger piston 5, what the chamber wall of valve body cavity of resorption 3 was arranged is opened with the sealed packet passage 4 be communicated with in case of casing, the gas of box house is successively by passage 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, reversely rotate 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 sealing gasket impacted bolt 8, at this moment plunger piston 5 upwards raises by plunger piston 5 under the effect of stage clip 6, along with the lifting of plunger piston 5, passage 4 is closed by plunger piston 5 gradually, realize airtight to institute's inflated with nitrogen in case, plunger piston 5 rises to the sealing gasket 7 on it and the annular boss 14 that arranges between valve body cavity of resorption 3 and valve body epicoele 9 always and pushes up and force together, the elastic force of stage clip 6 passes through sealing gasket 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.
