Abstract:
A valve base driven forced sealing ball valve, comprising a valve body (10), a first valve base (20), a valve ball (30), and a valve rod (40). The valve rod (40) drives the valve ball (30) to conduct a reciprocating rotation between switch positions, and the valve rod (40) further drives the first valve base (30) to reciprocate towards the valve ball (30). When the valve ball (30) is closed, the first valve base (20) is locked with the valve ball (30) to achieve forced sealing. The first valve base (20) is driven by a first valve base driving ring (50) to reciprocate towards the valve ball (30). The first valve base driving ring (50) is provided with internal threads. The first valve base (20) is provided with external threads.
