Problems solved by technology

However, in order to ensure that no internal leakage occurs in the existing ball valves, the ball, that is, the closing part, must be tightly pressed on the valve seat during installation. The torque is large when opening and closing, and the ball produces friction with the valve seat during rotation. , serious wear and tear, easy to cause leakage, reducing the reliability of the ball valve and shortening the service life of the ball valve

Abstract

The invention relates to an improved ball valve. The improved ball valve comprises a valve body, a left valve cover and a right valve cover, a valve ball, a left valve clack and a right valve clack, arotary shaft, and a control rod, wherein a cavity body is formed in the valve body; the left valve cover and the right valve cover are fixedly installed at the two ends of the valve body separately;the valve ball is rotationally arranged in the cavity body, and a left valve cavity and a right valve cavity are formed in the valve ball; the left valve clack and the right valve clack are arranged in the left valve cavity and the right valve cavity separately; the rotary shaft comprises a rotary rod and a handle; and the control rod comprises a pull rod and a control block. According to the improved ball valve, in an opening process, the left valve clack and the right valve clack are free from friction and wear, so that the service life can be prolonged, and the reliability can be improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline valves, in particular to an improved ball valve. Background technique [0002] Pipelines are usually used to transport media in industrial or civil infrastructure, where the pipeline is regulated due to changes in pressure or temperature. In order to adjust the flow, an adjustment mechanism, especially a ball valve, is used in the pipeline to ensure the best work. conditions and the safety of the environment. Ball valves usually use a sphere with a circular passage as the opening and closing element, and the sphere realizes the opening and closing action with the rotation of the valve body. The opening and closing part of the ball valve is a ball with a through hole, which rotates around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the channel. A traditional ball valve is usually a sphere with a through hole installed on the valve seat, and the open...
