ELASTIC CHECK VALVE FOR REDUCING PRODUCTION COST THROUGH SIMPLIFIED STRUCTURE, EXTENDING THE LIFE SPAN, AND SECURING CONVENIENCE IN THE USE

摘要

PURPOSE: An elastic check valve is provided to simplify structure and to secure economical efficiency by reducing the production cost and the maintenance cost. CONSTITUTION: An elastic check valve comprises a valve body(100) made of natural rubber or synthetic rubber; a reinforcing core member(160) of a metal material built in the valve body; and a fixing unit(140) for combining and fixing a cuff part(110) of the valve body, wherein the reinforcing core member is built, to a pipe(1), with watertightness. The valve body has the cuff part and an elastic opening and closing part(120) of Bill structure opening and closing by elastic force according to the discharge water pressure acting through the pipe. The elastic opening and closing part is integrally extended from the cuff part.
