摘要： PURPOSE: An air enclosure and a check valve thereof are provided, which remove concern that is unable to perform the function of the air interception by malfunction of a shutoff valve. CONSTITUTION: An air enclosure includes two outer films(2a,2b), more than one air tube, two first inner films(11a,11b), two second inner films, and more than one second air supply nozzle. More than one air tube is formed between two outer films by heat-sealing two outer films using a heat sealing unit. The first inner film is inserted between two outer films. The first inner film is exposed to the air tube. The second inner film is inserted between the first inner films. The second air supply nozzle is formed between two second inner films. The air tube is expanded by injecting the air of the high pressure into the second air supply nozzle.
