The split type ceramic spherical valve element comprises a valve element lower body. The connecting piece is positioned at the top of the valve core lower body; and the hemispherical valve core upper body is movably connected with the valve core lower body and is positioned above the connecting piece. The valve element upper body adopts the ceramic spherical surface, has super-strong wear resistance, overcomes the defect that a common cast iron spherical surface or a cast steel spherical surface is not wear-resistant, and reduces the frequency of overall replacement of the valve element, so that the service life of the whole valve is prolonged, and the cost of on-site spare parts and the maintenance cost are reduced. The split type design is adopted between the valve element lower body and the valve element upper body, so that the valve element upper body is convenient to replace after being damaged. 一种分体式陶瓷球面阀芯及圆顶阀，包括阀芯下体；位于所述阀芯下体顶部的连接片；以及与所述阀芯下体活动连接的且位于所述连接片上方的半球形阀芯上体。本实用新型中的阀芯上体采用陶瓷球面，具有超强耐磨性能，克服了通常铸铁球面或者铸
