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

The invention discloses a three-way ball valve which comprises a shell. An installing hole penetrating left and right is formed in the shell. A left end cover is installed at the left end of the shell, and a right end cover is installed at the right end of the shell. A left through hole is formed in the left end cover. A right through hole is formed in the right end cover. A middle through hole is formed in the side face of the shell. A ball is arranged in the installing hole. A penetrating communicating hole is formed in the ball. A middle hole is formed in the side face of the ball. First round grooves are formed in the portions, at the two ends of the communicating hole and the outer end of the middle hole, of the ball correspondingly. A through hole ball clack is connected in each first round groove in a sliding manner. A second round groove is formed in the ball face of the ball. A sealing ball clack is connected into the second round groove in a sliding manner. The ball is provided with a valve rod extending out of the shell. A driving mechanism used for driving the through hole ball clack and the sealing ball clack to move is arranged in the shell. The three-way ball valve is easy to use, convenient to use and safe, and abrasion of the ball is avoided.
Description
technical field [0001] The invention belongs to the technical field of pipeline valves, in particular to a three-way 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. 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 operati...
