Abstract
The invention discloses a top-mounted double-sealing three-section ball valve which comprises a valve body, a ball clack combination part located on a runner of the valve body, and a transmission mechanism fixedly connected with the ball clack combination part. The transmission mechanism comprises a vale rod penetrating through a support and a valve cover, and a valve rod nut connected with an actuator. A back seal is arranged on a rod body of the valve rod, and the back seal is located at the contact position between the sealing face of the valve cover and the valve rod. The top-mounted double-sealing three-section ball valve further comprises a sealing mechanism located below the valve body, and the sealing mechanism tightly adheres to the sealing face of the valve body. Due to the fact that a limiting device and the back seal are arranged, contact sliding friction between the sealing face of the valve body and the back sealing face of the valve cover does not exist any more in the opening and closing processes, and therefore the service life of the valve is prolonged, and the action of opening and closing torque is relieved. The transmission mechanism is arranged in a sealed support cavity, and therefore a transmission system can also operate flexibly and lightly in severe environments full of raised dust and corrosion gas. The top-mounted double-sealing three-section ball valve is safe and reliable.
