Abstract

The invention provides a sealing ball valve, which includes a valve body and a valve core ball, the valve core ball is arranged in the valve cavity of the valve body, and also includes a sealing ring and a compression ring, and the sealing ring is arranged in the valve cavity. Between the valve core ball and the valve body, the compression ring is arranged in the first hole of the valve body and pressed against the flange of the first skeleton of the sealing ring. In the sealing ball valve provided by the present invention, the setting of multiple lips of the sealing ring can enhance the sealing effect of the sealing ring. The setting of the spring can enhance the sealing performance between the sealing ring and the ball of the valve core. In addition, the inclined plate presses the first lip and the elastic force of the coil spring can compensate the gap between the sealing ring and the ball of the valve core due to wear. Maintain the tightness between the sealing ring and the valve core ball, thereby achieving the purpose of prolonging the service life of the ball valve.

Description

technical field [0001] The invention relates to the field of valves, in particular to a sealed ball valve. Background technique [0002] The ball valve is defined in the standard GB / T21465-2008 "Valve Terminology" as: a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. [0003] Chinese patent 201610040710.6 discloses a ball valve. In order to ensure the sealing effect of the ball valve, a second sealing groove is opened in the valve body, and the second sealing ring installed in the second sealing groove is in contact with the surface of the valve core ball. , there is a third sealing groove in the valve seat, the third sealing ring installed in the third sealing groove is in contact with the surface of the valve core ball, through the cooperation between the second sealing ring, the third sealing ring and the valve core ball , thus ensuring the sealing effect of the ball valve. However, during the rotati...
