Its performance characteristics are as follows:
one There are two types of paint on the valve surface: normal temperature and high temperature ；
two The sealing surface adopts eccentric structure, which can self compensate for wear and has good service life;
three When the eccentric hemisphere valve transports slurry, mixed flow liquid, dust and other media, it is not easy to produce precipitation, scaling, blocking and other phenomena;
four When the eccentric hemisphere valve is opened, the ball is separated from the shell without any contact surface, with small starting torque and flexible rotation. When closing, the squeezing and cutting action between the hemisphere and the valve seat can clean the dirt on the sealing surface to ensure good sealing performance 。
