Description
Technical Field
The utility model relates to an exhaust cover field especially relates to a from taking one-way vacuum vent valve filling flap.
Background
This company is the enterprise of professional production sack, the discovery adopts the liquid bag to come the device liquid thing in actual production, when need not using like this, the storage takes up an area of for a short time, it is convenient to accomodate, when needs use, just go in liquid adopts various suitable methods filling to the liquid bag, but whatever method adopts, because the leakproofness of operation is not good, all there is the air in the sack, one influences the actual measurement requirement of filling, two come chemical class liquid and air contact to take place chemical reaction easily, three is when not using the sack, the air is arranged unclean, make the storage space increase, influence product quality, and is not very practical.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a from taking one-way vacuum vent valve filling flap.
In order to realize the above-mentioned purpose, the utility model provides a from taking one-way vacuum vent valve filling flap, the fruit bag comprises a bag bod, the bag body on be equipped with the filling mouth, the filling mouth on be equipped with filling flap shell, filling flap shell on swing joint have a filling flap, the filling flap on be equipped with exhaust apparatus.
The exhaust device is a one-way exhaust valve, a plurality of exhaust holes are formed in the one-way exhaust valve, the one-way exhaust valve further comprises an air outlet, and the exhaust holes are communicated with the air outlet.
The one-way exhaust valve is movably connected with an exhaust valve cover.
The one-way exhaust valve comprises a valve body, a workbench and a lower workbench, wherein the upper workbench is positioned right above the lower workbench, and a vacuum pumping pump is erected at the upper end of the upper workbench.
The movable connection is a spiral connection.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a pair of take one-way vacuum vent valve filling flap can be very clean with the air when not filling liquid from taking, and the volume is very little, and weight is very light, the storage of being convenient for. After the liquid is filled, the air in the bag can be removed completely, and the placing space of the liquid is increased; and the adverse chemical reaction caused by the contact of the liquid and the air can be reduced, and the method is very practical.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is the schematic view of the filling port cover of the present invention.
Detailed Description
Referring to fig. 1 and 2, the filling port cover with the one-way vacuum exhaust valve comprises a bag body 1, wherein a filling port 2 is arranged on the bag body, a filling port cover shell 3 is arranged on the filling port 2, a filling port cover 4 is movably connected to the filling port cover shell 3, and an exhaust device 6 is arranged on the filling port cover 4. Exhaust device 6 be one-way discharge valve, one-way discharge valve on be equipped with a plurality of exhaust hole 4, one-way discharge valve still include the gas outlet, exhaust hole and gas outlet communicate with each other. The one-way exhaust valve comprises a valve body, a support workbench and a lower workbench, wherein the upper workbench is positioned right above the lower workbench, and a vacuum pumping pump is erected at the upper end of the upper workbench. The one-way exhaust valve is movably connected with an exhaust valve cover. When the external air pressure is less than the air pressure in the bag body, the air in the bag body is exhausted through the exhaust hole through the one-way exhaust valve and only can not enter or exit. The one-way exhaust valve can be spirally connected with an exhaust valve cover, so that the situation that redundant air cannot enter the bag body is guaranteed.
The utility model provides a pair of take one-way vacuum vent valve filling flap can be very clean with the air when not filling liquid from taking, and the volume is very little, and weight is very light, the storage of being convenient for. After the liquid is filled, the air in the bag can be removed completely, and the placing space of the liquid is increased; and the adverse chemical reaction caused by the contact of the liquid and the air can be reduced, and the method is very practical.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
