Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0030] Such as figure 1 , the present invention includes a main pipe for charging and deflation 1 and several airbag units 2 arranged in sequence along the main pipe for charging and deflation 1 . Each airbag unit 2 has an inflation and deflation control device 3 respectively, and each inflation and deflation control device 3 is respectively connected with the inflation and deflation holes 11 on the inflation and deflation main pipe 1 .

[0031] The first form of the described inflation and deflation control device 3 is: as figure 2 , 3 As shown, it includes a valve chamber 10 that communicates with the inner cavity of the airbag unit 2 and is connected with the inflation and deflation manifold 1 through the inflation and deflation holes 11 on the inflation and deflation manifold 1 . An air path is provided between the valve chamber 10 and the air fil...

Abstract

The invention relates to a series-connected air bag. The series-connected air bag comprises an inflation / deflation main pipe (1) and a plurality of air bag units (2) which are sequentially arranged along the inflation / deflation main pipe (1), wherein each air bag unit (2) respectively comprises an inflation / deflation control device (3), and each inflation / deflation control device (3) is respectively connected with an inflation / deflation hole (11) on the inflation / deflation main pipe (1). Inflation and deflation are completed through one main pipe. The series-connected air bag disclosed by the invention has simpler arrangement of a pipeline and can enable the series connection to be long enough according to needs. When more than one of the air bag units has air leakage, the other air bag units are not affected, thus the normal use of the whole series-connected air bag can be ensured.

Description

[0001] technical field [0002] The invention relates to a series airbag as a combined airbag, which can be placed in water and connected to aquaculture tools (such as sinking and floating fish tanks, aquaculture rafts), used for sinking and floating aquaculture tools, and can also be used for oil booms, ships, etc. Anti-sinking, lifesaving, salvage and floating of various water pipelines and pontoons. Background technique [0003] In the existing combined airbags, the inflation and deflation ports of each airbag are respectively connected to the gas source through respective branch trachea, such as Chinese patent application No. 2006102002295. Its main disadvantages are: firstly, there are many branch pipelines, not only the pipelines are messy, but also the combined airbags cannot be made into a long series connection structure, which cannot meet the needs of long-term operations, and the place of use is limited. In addition, because multiple airbags share one gas valv...
