Abstract
The utility model relates to a one-way exhaust valve for a flexible packaging bag, which comprises an exhaust valve base, an exhaust valve cover and an oily one-way separating elastic gasket, wherein the exhaust valve base is bowl-shaped; a ring-shaped wedge type groove is formed in the bottom of the exhaust valve base; an gas inlet hole is formed in the middle of the exhaust valve base; a ring-shaped wedge type lug is arranged on the lower edge of the exhaust valve cover; an gas outlet hole is formed in the top of the exhaust valve cover; the exhaust valve cover is buckled in the ring-shaped wedge type groove on the exhaust valve base through the ring-shaped wedge type lug; the oily one-way separating elastic gasket is arranged between the exhaust valve base and the exhaust valve cover; and the upper and the lower end surfaces of the oily one-way separating elastic gasket are respectively propped against the exhaust valve base and the exhaust valve cover. Through the adoption of the technical scheme, the one-way exhaust valve for the flexible packaging bag is encapsulated on the inner surface of the article packaging bag, to-be-exhausted gas in the flexible packaging bag can be exhausted by puncturing the part of the packaging bag, which is positioned on the outside of the one-way exhaust valve, and the air tightness of the flexible packaging bag can be maintained at the same time.
Description
Technical field
The utility model relates to a kind of blow off valve, particularly relates to a kind of flexible objects packaging bag one-way exhaust valve.
Background technology
Soft packaging bag in the prior art; All be to adopt packaged type that article are stored; Though extraneous gas gets into less than in the bag for packaging materials, some smells that need distribute or gas that article self send can not vapor away, and have influence on article itself.
The utility model content
In view of this; The technical matters that the utility model will solve is to provide a kind of soft packaging bag one-way exhaust valve, through the present technique scheme, the soft packaging bag blow off valve is encapsulated on the soft packaging bag inside face; Puncture the packaging bag that is positioned at the check valve outside; Promptly can the gas that need in the bag for packaging materials to discharge be discharged, and can keep the fgn leak tightness in the bag for packaging materials, thereby remedy the deficiency that exists in the prior art.
For solving the problems of the technologies described above; The technical scheme of the utility model is achieved in that a kind of soft packaging bag one-way exhaust valve; Comprise blow off valve base, exhaust valve cap and be stained with oily unidirectional obstruct elastomeric pad; Said blow off valve base is bowl-shape, is provided with the ring-type wedge hollow in the bottom of blow off valve base, in the middle of the bottom of blow off valve base, is provided with induction opening; The lower edge of said exhaust valve cap is provided with ring-type wedge type projection, and the top of exhaust valve cap is provided with air gate, and said exhaust valve cap is in the ring-type wedge hollow of ring-type wedge type projection spiral-lock on the blow off valve base; Saidly be stained with oily unidirectional obstruct elastomeric pad and be arranged between blow off valve base and the exhaust valve cap, the upper and lower end face of being stained with oily unidirectional obstruct elastomeric pad is pressed on respectively on blow off valve base and the exhaust valve cap.
Be provided with the circular-arc plush copper to lower convexity in the middle of the said exhaust valve cap inner top, the air gate on the said exhaust valve cap is arranged on a side of circular-arc plush copper.
Said air gate is provided with air-permeable paper.
The technique effect that the utility model reaches is following: a kind of soft packaging bag one-way exhaust valve; Through the present technique scheme; The soft packaging bag blow off valve is encapsulated on the bag for packaging materials inside face, punctures the packaging bag that is positioned at the check valve outside, promptly can the gas that need in the bag for packaging materials to discharge be discharged; And can keep the fgn leak tightness in the soft packaging bag; Air gate through the setting of exhaust valve cap upper offset and circular-arc plush copper are pressed on is stained with on the oily unidirectional obstruct elastomeric pad, makes the exhaust valve cap inner top annular occur and goes out the headroom, has increased to be stained with the outwards ventilative area of ventilation of oily unidirectional obstruct elastomeric pad; Air gate is provided with air-permeable paper, and airborne dust and other powdery object get in air gate and the discharge of stopping up gas to prevent or to intercept.
