The invention discloses a rotating tap valve core, which comprises a rotating screw, a movable ceramic plate connected with the rotating screw and driven by the rotating screw, and a stationary ceramic plate fitted with the movable ceramic plate; the top of the rotating screw is provided with a rotating head with anti-slip threads, two sealing grooves under the rotating head and used for installing the sealing ring, and a rotating joint at the bottom of the rotating screw; The convex platform of step structure is equipped with a clamp which fits with the convex platform to install the clamping joint. Two water guide holes are arranged on both sides of the static ceramic plate to realize the channel opening or closing when the movable ceramic plate rotates. The plane area of the two water guide holes is three-fourths of the plane area of the static ceramic plate. Only by gently turning the small angle of the valve core can achieve the effect of rapid water discharge, so that the switch of the valve core will not be too large and can ensure sufficient water output, stable and smooth level.

一种转动式龙头阀芯
本专利技术涉及阀芯的结构领域，特别涉及一种转动式龙头阀芯。
技术介绍
目前，市场上的阀芯安装在水龙头中，用以控制水流开关以及流量大小。用于水龙头的阀芯有半球阀、闸阀等，这两类阀芯是比较传统的，也是最普及的，半球阀通过阀芯一侧是球面另一侧是贯穿孔进行切换达到控制流体流量以及关合，而闸阀通过上下位移对流体流量以及关合进行控制。也有一些是通过转动动瓷片的方式实现与定瓷片的水道开合来实现开关水的，由于定瓷片上设有与水龙头进水腔室的进水口相通的通孔，动瓷片上设有与分别与水龙头出腔室和定瓷片的通孔相通的通孔，则龙头阀芯不仅控制水龙头出水的作用，而且还决定水龙头出水量的大小。然而水龙头的出水量由龙头阀芯上动、定瓷片通孔的孔径大小来决定，而通孔孔径的大小由动、定瓷片的宽度尺寸和结构来决定，这样为了保证水龙头的出水量，一般把动、定瓷片的宽度尺寸设置成较大，则动、定瓷片安装在阀芯套内时需占据阀芯套较多内径空间，而在阀芯套的外径不增大的前提下，只能缩小阀芯套的壁厚，从而降低了阀芯套的强度，使阀芯套的螺纹段在安装应力和水压冲击力的作用下而容易发生断裂，缩短了快开龙头阀...
