Abstract
The utility model discloses a one-way sealing film which comprises a sealing film body and is characterized in that an elastic film ring mouth round rib is arranged on the sealing film body; and the shape of the sealing film body is matched with the shape of a sheathed one-way valve clack. The valve clack is fit more tightly with a mouth of a valve holder through the one-way sealing film and hard to deform and warp, can generate better gas tightness effect, can guarantee non-gas leakage, can work stably and reliably and is hard to damage.
Description
Technical field
The utility model relates to the clapper body and function one-way sealing film of inflator suction ports such as a kind of various air bag, airbag, floatage body, water survival bag, high-altitude buffering pneumatic cushion.
Background technique
Though existing breather cheek valve clapper has certain elasticity; But for can be under return spring work proper functioning; Need to guarantee to have certain rigidity, the conformability of itself and valve seat mouth is not fine, especially individual layer lobe body; In the middle easy deformation that works long hours, cause the tightness variation.The breather check valve lobe that has is provided with flat sheet membrane, but flat sheet membrane is fragile, and reliability is relatively poor.
Summary of the invention
The utility model purpose is to the defective of existing technology a kind of one-way sealing film that is used on the breather cheek valve clapper to be provided.
The utility model adopts following technological scheme for realizing above-mentioned purpose:
A kind of one-way sealing film comprises the sealing film body, it is characterized in that: said sealing film body is provided with elastic membrane collar extension circle muscle, and said sealing film body shape is complementary with the clapper shape of being overlapped.
It is further characterized in that: said sealing film body thickness 0.3mm-2.0mm.
Further said elastic membrane collar extension circle muscle diameter is about 3-6 times of thickness.
It is tightr that the utility model makes flap and valve seat mouth fit, and is not easy to be out of shape warpage, produces good tightness effect, guarantees air tightly, and working stability is reliable, and is not fragile.
Description of drawings
Fig. 1 is the utility model schematic representation;
1, sealing film body; 2, elastic membrane collar extension circle muscle.
Embodiment
A kind of one-way sealing film as shown in Figure 1 comprises sealing film body 1, and said sealing film body 1 is provided with elastic membrane collar extension circle muscle 2, and said sealing film body 1 shape is complementary with the clapper shape of being overlapped.Said sealing film body 1 thickness 0.3mm-2.0mm.Said elastic membrane collar extension circle muscle 2 diameters are about 3-6 times of thickness.
The utility model is enclosed within to make flap and valve seat mouth fit on the suction valve clapper tightr, is not easy to be out of shape warpage, produce good tightness effect, guarantee air tight.
