Abstract

The invention belongs to the technical field of pipeline valves, and discloses a ball valve which comprises a valve body and a valve ball. The valve body is provided with an inlet, an outlet, an inlet runner, an outlet runner and a control groove, and the valve ball is located in the valve body and provided with a control plate and a through hole. The control plate extends into the control groove to divide the control groove into a first control groove and a second control groove, and the control plate can reciprocate along the control groove to drive the valve ball to rotate relative to the valve body so as to control the communication relation between the through hole and the inlet and the communication relation between the through hole and the outlet. One end of the inlet runner communicates with the inlet, the other end of the inlet runner selectively communicates with the first control groove and the second control groove, one end of the outlet runner communicates with the outlet, and the other end of the outlet runner selectively communicates with the second control groove and the first control groove. The ball valve is used in a high-pressure pipeline, not only is low in manufacturing cost, but also has smaller weight and size, and has higher installation flexibility and use convenience.

Description

technical field

[0001] The invention belongs to the technical field of pipeline valves, in particular to a ball valve. Background technique

[0002] The opening and closing part of the ball valve is a ball with a through hole, which can achieve the purpose of opening and closing the channel by rotating around the axis perpendicular to the channel. Ball valves have been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rocket and other departments, as well as people's daily life, because of their advantages such as small fluid resistance, simple structure, compactness and reliability, convenient operation, rapid opening and closing, and wide application range. middle.

[0003] However, the current traditional structure of the ball valve has the following problems in the process of opening or closing:

[0004] 1. When the ball valve is used in a high-pressure pipeline, because the pressure difference before and after the bal...
