PURPOSE: An airtight cylinder valve using a gasket is provided to reduce manufacturing time because a welding work is not required and to prevent fluid leakage. CONSTITUTION: An airtight cylinder valve using a gasket comprises a handle (60), a first passage (70), a second passage (80), and a diaphragm assembly (100). The handle is rotatable in forward and backward directions. Fluid flows in the first and second passages. The diaphragm assembly connects and disconnects the first and second passages to/from each other depending on the rotation of the handle. The diaphragm assembly comprises a seat member, a gasket, a first diaphragm, and a pad member. |
