Problems solved by technology
In order to improve the comfort of the existing inflatable equipment, and to prevent a single airbag from leaking in a certain place during use, the entire equipment cannot be used. Therefore, many inflatable equipment are now changed to a multi-airbag method. Other airbags can ensure that the equipment can be used normally; but to inflate multiple airbags, it is often necessary to set a valve for each airbag separately
Existing air valves cannot meet the needs of simultaneous inflation or deflation of multiple independent airbags that are connected in parallel and do not communicate with each other.

Embodiment Construction
[0027] A method for using a valve with multiple gas path closing functions, comprising the following steps:
[0028] Step 1, preparatory work: select an appliance composed of multiple airbags, and connect the trachea of the multi-airbag appliance with the trachea 60 of the multi-functional valve core with a straight-through tube; if the number of airbags is less than the number of trachea 60, Close the unconnected air distribution pipe 60 with a plug, or directly tie the air distribution pipe 60 to seal; if the number of airbags is more than the number of air distribution pipes 60, it is necessary to increase the number of multi-functional valve cores;
[0029] Step 2, inflation: fix the air needle joint 70 on the pump, insert the needle bar 71 into the through hole 12, push the plug 50 away from the valve core 15 with the needle 73, until the magnetophilic metal cap 40 is separated from the magnetic ring 20, Separation between valve 62 and spherical head 14; At this moment,...

The present invention relates to a method for using an air valve with multi-airway closing function, comprising the following steps: Step 1, preparatory work: select an appliance composed of multiple airbags, connect the trachea of the multi-airbag appliance with the air distribution tube 60 of the multi-functional air valve core respectively Connect with a straight tube; step 2, inflate: insert the needle bar 71 into the through hole 12, push the plug 50 away from the valve head 16 with the needle 73, until the magnetophilic metal cap 40 is separated from the magnetic ring 20, and the valve 62 and the spherical valve are separated. The head 14 is separated; the gas in the pinhole 72 can deliver air to the air distribution pipe 60 through the gas distribution valve 62; Step 3, exhaust: separate the air needle joint 70 from the pump, and the air bag will be exhausted; Step 4, to Multiple airbags in parallel for differential air pressure adjustment: press the airbag corresponding to the trachea 70 to perform differential air pressure adjustment; multiple independent airbags connected to the air valve can be simultaneously inflated or exhausted.
Description
technical field [0001] The invention relates to the field of gas delivery, in particular to a method for using a gas valve with multiple gas path closing functions. Background technique [0002] In the construction process of environmental art projects, to protect construction personnel and works, inflatables composed of airbags are often used as buffer protection equipment, and airbags are also used as buffer safety protection equipment during firefighting; when working in the field or in temporary spaces To create a comfortable environment, inflatable sofas, inflatable beds and related inflatable equipment will also be used in order to reduce weight, heat preservation and anti-collision. In order to improve the comfort of the existing inflatable equipment, and to prevent a single airbag from leaking in a certain place during use, the entire equipment cannot be used. Therefore, many inflatable equipment are now changed to a multi-airbag method. Other airbags can ensure tha...
