Description
Technical Field
The invention relates to inflation matching equipment, in particular to a valve for simultaneously inflating and exhausting independent multi-airbag sports equipment.
Background
The main function of the existing valve core is to inflate or deflate an object connected with the valve core through special equipment. Particularly, in the existing inflatable sports apparatus, the inflatable sofa and the mattress, in order to improve the use comfort and overcome the defect that the whole inflatable article can not be used when one point of the article with a single air bag leaks, and simultaneously, the characteristic that air flows from a high-pressure position to a low-pressure position quickly is overcome, a multi-air-bag mode is adopted. However, the multi-airbag inflation often needs to be provided with an air distributing device or a valve after the valve. The prior valve core can not meet the requirements that a plurality of independent air bags which are connected in parallel and have no mutual air circulation need to be inflated or deflated simultaneously. The prior art is adopted to inflate or deflate a plurality of independent air bags with mutually non-communicated air, and air pipes of the plurality of air bags need to be controlled and adjusted through other valves.

All parts on the air valve are made of flexible rubber materials, and the air needle joint can be connected with a common inflator for use.
When the needle rod is completely inserted into the air hole, the needle top just penetrates out of the air hole and pushes the reinforcing rubber block covered on the air hole open, so that a cavity through which air can flow is formed between the elastic cover and the valve core.
By adopting the technical scheme of the invention, the invention has the following beneficial effects:
1) the invention can simultaneously inflate or exhaust a plurality of independent air bags connected with the air valve, and can keep the air pressure of the air bags consistent;
2) when the air needle is not inserted, the air between the independent air bags connected with the air needle is not communicated, so that the air can not move to other air bags after each independent air bag is pressed;
3) the multiple air bags connected with the invention have the same independent pressure bearing capacity with the air bag provided with a single air valve, and are particularly suitable for being installed and used on sports equipment consisting of the independent multiple air bags;
4) by pressing and pulling the air distributing pipe on the air distributing valve, differential air pressure adjustment among air bags can be realized.
