Abstract
A ceramic balance valve structure includes a valve tube and a pressure regulating member each of which is made of ceramic material. The valve tube is formed with a through hole and two annular grooves. The pressure regulating member is slidably mounted in the through hole of the valve tube and is provided with two water guide grooves corresponding to the annular grooves of the valve tube. The pressure regulating member is provided with a balance wall located between the two water guide grooves and has two opposite ends each provided with a connecting hole. Thus, the valve tube and the pressure regulating member have a ceramic surface contact therebetween to facilitate a sliding motion of the pressure regulating member and to prevent the pressure regulating member from being jammed in the valve tube.
