A valve suitable for mounting on an airbag product

Abstract

The invention relates to a valve suitable for being mounted on an airbag product, which comprises a valve casing, wherein an upwards extended threaded connection part is arranged in the middle of the upper surface of the valve casing, and, at the circumference, is in threaded connection with glands used for fixing the valve onto the airbag product. The valve is characterized in that the glands are two, namely the first gland and the second gland below the former; the inner layer of the airbag product is pressed between the second gland and the upper end surface of the valve casing, and the outer layer thereof is pressed between the first gland and the second gland; against the two-layer structure of the used airbag, two fixing positions are arranged on the valve; and the second gland and the upper end surface of the valve casing form one fixing position for the inner layer film of the air bag, and the first and the second glands form one fixing position for the outer layer film of the air bag, that is, the valve can fix the two layers of films of the air bag respectively. Therefore, the valve is suitable for being mounted on the airbag product.

Description

technical field [0001] The invention relates to an inflation and exhaust valve used on equipment that needs to be inflated, in particular to a valve suitable for being installed on an airbag product. Background technique [0002] Equipment that needs to be inflated, such as an inflatable bed and an inflatable boat, are all provided with inflation valves. A conventional inflatable valve includes a housing, in which there is a working chamber communicating with the working environment and an air intake chamber communicating with the outside world. The working chamber and the air intake chamber communicate with each other through the valve port. Spool assembly for closing tendency. [0003] Such as a patent No. ZL01236759.1 (announcement number is CN2480182Y) Chinese utility model patent "inflating valve for air bed", patent No. ZL201120322164.8 (announcement number is CN202203458U) Chinese utility model patent "a kind of inflating valve" all Such an inflation valve is disclo...

AI Technical Summary

Problems solved by technology

[0005] If the inflation valve is used on a product with an air bag, the existing installation method cannot be firmly combined with this product, because the existing inflation valve has only one fixed position, and the air bag generally has a two-layer structure, and the outer layer is usually not Sealed nylon and other relatively hard materials play a protective role on the outside, and the inner layer is usually a bag made of other soft materials such as PU. If the two-layer air bag is directly pressed on the outer step surface of the gland and valve housing , due to the different friction coefficients between the double-layer structure of the airbag, the airbag is easy to slip and folds occur in the double-layer airbag

[0006] In addition, the valve core assembly of the inflation valve adopts a valve plate made of flexible material, which only opens the valve port through the deformation of the valve plate, and the degree of deformation of the valve plate is limited, so the air flow through the valve port is relatively small, and the inflation efficiency is low.

Inflatable valves generally do not have the function of exhausting. Although some exhaust valves can exhaust, the exhausting operation is very inconvenient. When exhausting, it is necessary to use fingers or tools to keep the one-way inflation valve core assembly in the top open state. Let the one-way inflation valve core assembly no longer block the valve port, and keep the valve port normally open to exhaust. If the equipment that needs to be inflated is large, the exhaust time will be very long, so the exhaust process will be tiring, and there will be A special exhaust device will be installed on the equipment that needs to be inflated, but it will increase the cost
