A pressure vessel includes an inner liner, a tubing connector, and an anti-leakage unit. The inner liner is disposed in an outer shell and defines an inner space. The tubing connector is disposed outwardly of the inner space and is welded to the outer shell. The anti-leakage unit has inner and outer sealing rings, and a clamping member that extends into the tubing connector and the inner space and that has inner and outer end flanges. The inner and outer end flanges are disposed inside and outside the inner space, respectively. The inner and outer end flanges cooperatively provides a clamping force to press the inner and outer sealing rings against the inner liner and the tubing connector, respectively. |

1. A pressure vessel comprising:
an outer shell defining an accommodating space therein, and having a top wall and a surrounding wall that extends downwardly from said top wall and that is formed with a side through-hole; an inner liner disposed in said accommodating space, and having
an inner surface that defines an inner space,a top wall that is attached to said top wall of said outer shell, anda surrounding wall that extends downwardly from said top wall of said inner liner, that is attached to said surrounding wall of said outer shell, and that is formed with a liner through-hole which is aligned with said side through-hole along an axis; a tubing connector disposed outwardly of said inner space, welded to an exterior of said outer shell, and defining a fluid channel that extends along the axis; an anti-leakage unit having a clamping member and elastic inner and outer sealing rings, said clamping member having a tube body and inner and outer end flanges, said tube body extending along the axis through said side through-hole and said liner through-hole and into said inner space and said fluid channel, said inner and outer end flanges extending outwardly and respectively from two opposite ends of said tube body, said inner end flange and said inner sealing ring being disposed in said inner space, said outer end flange and said outer sealing ring being disposed outwardly of said inner space, said inner and outer end flanges cooperatively providing a clamping force to press said inner and outer sealing rings against said inner liner and said tubing connector, respectively; and a flexible diaphragm disposed in said accommodating space to partition said accommodating space into two separated spaces. |
