The gas water heater water inlet joint apparatus of claim 5, wherein said sealing stem assembly further comprises a central stem and a first disk, said central stem being disposed through said valve body, said central stem being movable within said valve body, said first disk being disposed around said central stem, said support assembly being supported by said first disk, said support assembly applying a force through said first disk that urges said sealing disk toward said boss assembly.
7. The gas water heater water inlet joint apparatus of claim 6 wherein said support member assembly includes a first spring, said first spring being sleeved on said central rod, both ends of said first spring being connected to said first disk and said valve body, respectively, said first spring applying a force through said first disk that urges said sealing disk toward said boss assembly,
and/or the sealing rod assembly further comprises a reset disc, the reset disc extends outwards along the radial direction of the central rod from one end of the central rod, which is positioned outside the valve main body,
and/or the limiting assembly is arranged between the sealing disc and the first disc and abuts against the first disc to limit the movement of the sealing rod assembly.
8. The gas water heater water inlet joint apparatus of claim 7, wherein said limiting assembly includes a connecting end, a transition portion and a contact end, said connecting end is connected to said driving assembly, said contact end abuts against said first disk and limits movement of said sealing rod assembly, said transition portion is made of an elastic material, and said connecting end and said contact end change relative positions through said transition portion.
9. A water heater characterized in that it comprises a gas water heater water inlet joint device according to any one of claims 1-8.
