6 , Structural features of engineering ceramic gate valves:
a) The valve adopts double-sided sealing to achieve double-sided wear resistance. The flushing and flowing area of ??the inner cavity is lined with ZTA ceramics. The sealing of the valve closing part is controlled by the medium pressure. The specific pressure generated by the difference forms a seal;
b) The slag discharge type engineering ceramic valve seat adopts protective lip technology: the inner diameter of the valve seat ceramic sealing ring has a protective lip (patented) structure, which can effectively prevent the valve from impending When closing, a hard object shears the ceramic sealing ring from the inner diameter.
