Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a new two-way ball valve. Background Art

[0002] In daily life, ball valves are often used to switch waterways. A ball valve is a valve whose opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat welded with hard alloy, which is particularly suitable for media containing fibers, tiny solid particles, etc. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the driving mode. As for manual ball valves, there are some shortcomings in the ball valves on the market. When switching the water line, since the channels inside the ball valve are all columnar channels, these channels do not buffer the water flow. Water flows in and out, and there is water flow impacting the channels during conversion. After a long time, the channels will be damaged, affecting the use effect of the ball valve. In addition, the columnar channels will not block some tiny debris, which can easily bring the debris into the water inlet terminal, affecting the normal use of the terminal equipment. In addition, if the ball valve is opened or closed for a long time, the ball valve will deviate from its original position due to other factors. For example, the closed position becomes a small open position or the open position becomes a small closed position, which will affect the normal operation of the ball valve and water line changes.

[0003] Therefore, in view of the above problems, the existing ball valve technology needs to be further improved. Utility Model Content
