Abstract
The utility model discloses a top-entry bidirectional sphere valve comprising a valve body and a sealing assembly axially installed on a lower shaft hole of the valve body. The sealing assembly comprises a ball body, a ball clack rotating shaft arranged between a ball body sealing surface and a valve body sealing surface, and an operation head embedded in the ball body. When being rotated, the operation head drives the ball body to rotate around the ball clack rotating shaft and thus the ball body sealing surface and a valve base sealing surface can be in tight fit. The top-entry bidirectional sphere valve also comprises a valve rod fixedly connected with the operation head. The problem in the prior art that it is difficult for the conventional top-entry hard seal ball valve to achieve zero leakage is solved. The top-entry bidirectional sphere valve reduces the opening/closing moment, saves energy, has improved reliability, feasibility and economical efficiency and can achieve favorable benefit.
