Described valve gap 3 is that diameter is less than the flat bowl shaped structure of valve seat 1, the bowl bottom of valve gap 3 has valve gap exhaust port 3-1, in the bottom, there is positioning ring 3-2 in central authorities, valve gap 3 is arranged in valve seat 1, the opening of valve gap 3 is towards valve seat inlet hole 1-1, the edge of valve gap 3 is embedded in the groove of valve seat 1 bottom periphery, forms concave convex button;
Self-styled valve block 2 is slab organizations, and there is the cross opening in self-styled valve block central authorities, and self-styled valve block 2 is arranged between the positioning ring (3-2) of the valve seat inlet hole 1-1 of valve seat 1 and valve gap 3, the fixing self-styled valve block 2 of central locating ring phase buckle in valve seat 1 and valve gap 3 bottoms.
Described valve seat (1) forms concave convex button, the mutual lock sealing of this concave convex button with valve gap (3) edge embedding.
Described valve seat (1) is provided with positioning ring with valve gap (3) central authorities, and this positioning ring phase buckle is fixed self-styled valve block (2).
Described self-styled valve block (2) adopts central zone cross open flexible glue to make.
Advantage of the present invention: can make the interior residual air of package bag under the Action of Gravity Field of top goods, discharge from one-way exhaust valve.
In carrying or when falling from eminence, the air in bag can be discharged from one-way exhaust valve when the package bag of filling goods, reduces the shock wave that in bag, residual air produces, and reduces or avoids consequent bale broken; Simultaneously, one-way exhaust valve can also avoid ambient air can not enter in bag, moistureproof, leakproof.
Description of drawings
Fig. 1 is that the present invention amplifies rear sectional view;
Fig. 2 is parts unfolded drawing of the present invention.
Symbol description in figure: valve seat 1, valve seat inlet hole 1-1, positioning ring 1-2, self-styled valve block 2, valve gap 3, valve gap exhaust port 3-1, positioning ring 3-2, package bag inwall 4, package bag exhaust port 4-1.
Embodiment
The below is described in detail the present invention with best embodiment.
As shown in Fig. 1-2, one-way exhaust valve comprises package bag, and package bag exhaust port 4-1 is arranged on package bag inwall 4, also comprises the one-way exhaust valve that is made of valve seat 1, self-styled valve block 2 and valve gap 3;
Described valve seat 1 is hat-shaped structure, and valve seat inlet hole 1-1 is arranged at the bottom of valve seat 1, and in the bottom, there is positioning ring 1-2 in central authorities, and valve seat 1 covers on the position that package bag exhaust port 4-1 is arranged on package bag inwall 4, and the edge of valve seat 1 is connected with package bag inwall 4;
Described valve gap 3 is that diameter is less than the flat bowl shaped structure of valve seat 1, the bowl bottom of valve gap 3 has valve gap exhaust port 3-1, in the bottom, there is positioning ring 3-2 in central authorities, valve gap 3 is arranged in valve seat 1, the opening of valve gap 3 is towards valve seat inlet hole 1-1, the edge of valve gap 3 is embedded in the groove of valve seat 1 bottom periphery, forms concave convex button;
Self-styled valve block 2 is slab organizations, and there is the cross opening in self-styled valve block central authorities, and self-styled valve block 2 is arranged between the positioning ring (3-2) of the valve seat inlet hole 1-1 of valve seat 1 and valve gap 3, the fixing self-styled valve block 2 of central locating ring phase buckle in valve seat 1 and valve gap 2 bottoms.
Described valve seat (1) forms concave convex button, the mutual lock sealing of this concave convex button with valve gap (3) edge embedding.
Described valve seat (1) is provided with positioning ring with valve gap (3) central authorities, and this positioning ring phase buckle is fixed self-styled valve block (2).
Described self-styled valve block (2) adopts central zone cross open flexible glue to make.
Characteristics of the present invention:
1, valve seat is hat-shaped structure, and crown has recess outward, and vent is arranged; Recess is used for pressing the required sticking note of article or welding filter screen, and there is positioning ring in valve seat inside crown position central authorities, and place, inwall top is concave groove.
2, valve gap is flat bowl shaped structure, and vent is arranged at the bottom, and center of inside has positioning ring, the rim of a bowl position just with valve base inner wall concave groove formation concave convex button.
3, the mutual locking function of concave convex button seals one-way exhaust valve, thereby stops entering of ambient air.
4, after valve seat and valve gap interlock, formed valve pocket, self-styled valve block is snapped in central locating ring in valve seat and valve gap mutually.
5, the positioning ring of valve seat and valve gap center of inside forms the phase buckle, and fixing self-styled valve block makes it stability and sealing and strengthens, and better stops ambient air to enter in bag.
6, self-styled valve block is the cushion compound that there is the cross opening in central authorities, when package bag was squeezed, in bag, an air can make in outlet valve self-styled valve block open, thereby discharged an air in bag, after air is drained, self-styled valve block is because of sucking action and the atmospheric pressure effect of cushion compound self, and the cross open of self-styled valve block central authorities can automatic involution, and the outer part of this cushion compound is at ordinary times and is close to the valve seat state, thereby stop entering of air, play waterproof, protection against the tide, the effect of leakproof.
7, one-way exhaust valve and the bag side rear formation air vent that is interlockingly connected makes that bag interior air is faster discharges from the bag exhaust port, accelerates exhaust velocity, reduces snapping final vacuum hole and is obstructed.
It should be noted that at last: obviously, above-described embodiment is only for example of the present invention clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being amplified out thus or change still are among protection scope of the present invention.
