A multifunctional two-way fluid check valve (1) includes a hollow sleeve (100) internally defining a first (120) and a second chamber (130), and an inclined stop shoulder (140); an inflation-valve connecting head (150) located below the hollow sleeve (100) and having a gas mouth (a) mounted therein; a first (200) and a second (300) valve body elastically movably located in the first (120) and the second (130) chamber, respectively; and a gas inlet connector (400) mounted to an upper end of the second chamber (130). The second valve body (300) has an external inclined section (320) with a first airtight gasket (324) thereon in contact with an inner inclined shoulder section (133) on the second chamber (130), and a lower outer surface with a second airtight gasket (332) thereon in contact with the inclined stop shoulder (140) on the hollow sleeve (100). At least one release port (135) is formed on a wall of the second chamber (130) below the inner inclined shoulder section (133) and above the beveled stop shoulder (140). |
