Abstract

A height-adjustable valve stem assembly includes a base body having an interior for engaging with a valve stem and an exterior connected to a valve connector which is connected to a valve. An inner surface of the valve connector and an outer surface of the valve stem respectively include a first engaging section and a second engaging section. An adapter is engaged with an interior of the valve connector. An outer surface of the adapter is provided with a third engaging section to engage with the first engaging section. An inner surface of the adapter is provided with a fourth engaging section to engage with the second engaging section. The adapter enables mutual engagement between the base body and the valve stem, and through a relative engagement stroke among the base body, the adapter, and the valve stem, a height of the base body on the valve is adjusted.
