Manual and automatic integrated double-valve-rod flange ball valve

Abstract

The utility model discloses a manual-automatic integrated double-valve-rod flange ball valve which comprises a valve body, a ball body valve element, an automatic valve rod, a manual valve rod and the like, the automatic valve rod comprises an automatic inner valve rod and an automatic outer valve rod, the manual valve rod comprises a manual inner valve rod and a manual outer valve rod, and when an automatic driving piece drives the automatic outer valve rod to rotate in the forward direction, the automatic outer valve rod is driven to rotate in the forward direction. The automatic inner valve rod is driven to synchronously rotate in the forward direction, then the ball valve element is driven to form forward rotation sealing opening and closing in the valve seat, the ball valve element drives the manual inner valve rod to synchronously rotate in the forward direction, and the manual inner valve rod slides relative to the manual outer valve rod; when the manual driving piece drives the manual outer valve rod to rotate reversely and drives the manual inner valve rod to rotate synchronously and reversely, then the ball valve element is driven to form reverse rotation sealing opening and closing in the valve seat, the ball valve element drives the automatic inner valve rod to rotate synchronously and reversely, and the automatic inner valve rod slides relative to the automatic outer valve rod. Therefore, the ball valve core can be automatically and manually driven, and the operations of the ball valve core and the ball valve core do not interfere with each other.
