STRUCTURE AND PURPOSS of SJKI lnternal-slot type slowly-closed daming check valve

Used on the pump outlet of a water supply system to prevent mediums back-flow,water-hammer and water shock,combining three functions as an electric valve,check valve and water hammer remover,capable of effectively raisingsafety and reliability of the water supply system,integrating the technical principle of slow-open,speed valve,slow-close renoving water hammer and preventing both pump-starting and pump-stopping water hammers from being formed.The gate can automatically carry out open -close upon the operation rules of the water pump just by operating the pump to open or close electrically.This valve features a big flow and a small pressure loss.Reliable sealing performance,easy installation,debugging and maintenance and a long duration.
