Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ball valves, in particular to a new type of 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. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels. 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 diverting or converting water, 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.
