Water-guiding hole is relative with the center hole of silicagel column; Moving ceramic plate is in a phase place by water-guiding hole sealing, in another phase place, and water guide notch is corresponding with water-guiding hole.

The water tap of described a kind of ceramic valve core, its special way is: on the outer circumferential surface of described Dingtao ceramics, have on a diameter line and along axis location projection;

On described spool chamber inwall, have positioning groove, positioning convex and positioning groove are chimeric.

The water tap of described a kind of ceramic valve core, its special way is: there is an annulus block plate described valve rod and connecting rod intersection, also comprise a sealing gasket;

Sealing gasket is arranged on annulus block plate, and the upper surface of sealing gasket and the laminating of the top walls panels of spool chamber reach liquid sealing.

The water tap of a kind of ceramic valve core of the utility model, owing to adopting such structure, Dingtao ceramics and moving ceramic plate that spool is made by stupalith form, and stupalith cost is low, wear-resisting and corrosion-resistant; In prior art, spool is made of copper, and adds complex process, corrosion-resistant comparing not, and yield rate is high, long service life.
