Description
Technical field
The utility model relates to pontoon bridge or sea berth stringer technical field, especially a kind of Gao Cheng of single layer structure
Carry strength capsule.
Background technique
Air bag is that one kind can provide the inflatable structure of buoyancy and directly stranded pressure-bearing.Air bag early stage is mainly used in
Ship for civil use builds being lauched after completing, from the 10,000 tons large ship of initial hundred tonnes of spitkits till now, using more
Come more, air bag has played important function.In addition to this, such air bag is also used for mobile ground heavy construction component.
The air valve seat of such air bag is by being generally molded and being vulcanized by rubber valve seat and metal valve cock, due to rubber valve
The intensity of seat is less than the intensity of air bag utricule, and when the load of air bag is excessive, the pressure of inside air bag may destroy rubber valve
Seat, to reduce the safety of air bag.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of high-bearing capacity air bag, the air valve seat of the air bag is not easy
Damage, this safety are higher.
In order to solve the above-mentioned technical problem, the utility model includes that utricule and setting are used on utricule to the inside of utricule fill
The air valve seat of gas and deflation, the air valve seat include metal valve cock and rubber valve seat, and metal valve cock and rubber valve seat are molded
And vulcanize integrally, bottom and the utricule of the rubber valve seat are sealing adhesive, and are provided with enhancement layer on the rubber valve seat.
The rubber valve seat includes upper rubber layer and lower rubber layer, and the enhancement layer is arranged in upper rubber layer and lower rubber layer
Between, and be bonded together.
The material of the enhancement layer is identical as envelop materials.
The material of the utricule is single layer rubber-coated fabric.
The second enhancement layer is bonded between the rubber valve seat upper surface and utricule.
Sealant is provided between the rubber valve seat and the second enhancement layer, the second enhancement layer and utricule.
Due to being provided with enhancement layer on rubber valve seat, rubber valve seat does not allow easy fracture, improves the safety of air bag.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the longitudinal section view of the air valve seat axis of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing, cited embodiment, is only intended to help to manage
The utility model is solved, should not be construed as the restriction to utility model protection range, for those skilled in the art
For, under the premise of not departing from the utility model principle and thought, the utility model can also be made improvements and modifications, these
Improvement and modification also fall into the range of the utility model claims protection.
As shown in Figure 1, the utility model includes that utricule 1 and setting are used on utricule 1 to 1 inner inflatable of utricule and deflation
Air valve seat 2, the utricule 1 be cylindrical type, both ends be hemispherical or spherical crown shape or cone cell.As shown in Fig. 2, the air valve seat 2
Including metal valve cock 21 and rubber valve seat 22.The rubber valve seat 22 is circle, and metal valve cock 21 is arranged in rubber valve seat
Rubber valve seat 22 is simultaneously run through in 22 centre, and metal valve cock 21 and rubber valve seat 22 are molded and vulcanize integral.It is set on utricule 1
Be equipped with the matched hole of 22 shape of rubber valve seat, the edge secure bond in hole is one on 22 bottom margin of rubber valve seat and utricule 1
It rises.Since the intensity of rubber valve seat 22 is generally below the intensity of utricule 1, in use, once pressure mistake in utricule 1
Greatly, rubber valve seat 22 is easy to happen fracture, for this purpose, being additionally provided with enhancement layer 23 on the rubber valve seat 22.
As preferred embodiments, the rubber valve seat 22 includes upper rubber layer 221 and lower rubber layer 222, the reinforcement
Layer 23 is arranged between upper rubber layer 221 and lower rubber layer 222, and is bonded together.
As preferred embodiments, 23 material of enhancement layer is identical as 1 material of utricule.
As preferred embodiments, 1 material of utricule is single layer rubber-coated fabric.
Further, the second enhancement layer 3 is also bonded between 22 upper surface of rubber valve seat and utricule 1.
Further, the rubber valve seat 22 and the second enhancement layer 3, are provided with sealant between the second enhancement layer 3 and utricule 1
