<p>A pressure vessel includes an inner liner (2), a tubing connector (3), and an anti-leakage unit (5). The inner liner (2) is disposed in an outer shell (1) and defines an inner space (201). The tubing connector (3) is disposed outwardly of the inner space (201) and is welded to the outer shell (1). The anti-leakage unit (5) has inner and outer sealing rings (50, 52), and a clamping member (51) that extends into the tubing connector (3) and the inner space (201) and that has inner and outer end flanges (511, 512). The inner and outer end flanges (511, 512) are disposed inside and outside the inner space (201), respectively. The inner and outer end flanges (511, 512) cooperatively provide a clamping force to press the inner and outer sealing rings (50, 52) against the inner liner (2) and the tubing connector (3), respectively.</p> |
