Technical Field

[0002] The ceramic valve core is a core valve component made of ceramic material, which is widely used in faucet outlets and multiple industrial fields. Its main features are corrosion resistance, wear resistance and good sealing. In the existing field, most of the valve cores are driven by a rotating core. The fork at the lower end of the rotating core drives the movable valve plate to rotate, so that the water outlet hole on the movable valve plate corresponds to the water inlet hole on the static valve plate, and finally the water flows out from the hole on the rotating core. When the user needs to adjust the amount of water, it is necessary to rotate back and forth between the force between zero and maximum flow. The force is not easy to grasp, which not only easily causes waste of water resources, but also is troublesome to rotate back and forth, affecting the user experience. Utility Model Content

[0009] Furthermore, a gear mark is provided on the upper end surface of the shell, and the gear mark corresponds to the positioning hole.

[0010] Furthermore, the gear position is divided into three gears, namely "0", "1" and "2", wherein the "0" gear is a zero flow position and the "2" gear is a maximum flow position.

[0011] Furthermore, there are multiple positioning holes, and when the valve plate is deflected to be parallel to the end face of the valve port, it is at the "0" position, and when it is deflected to be perpendicular to the end face of the valve port, it is at the "2" position.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The ceramic valve core is adjusted in stages, and positioning holes are provided at equal intervals along the middle edge of the shell through which the second rotating rod passes.
