FLUID FLOW REGULATING VALVE USING THERMAL EXPANSION MATERIAL

摘要

A FLUID FLOW REGULATING VALVE (100) USING A THERMAL EXPANSION MATERIAL (125). THE VALVE INCLUDES A BODY (110) PROVIDED WITH INLET AND OUTLET PORTS (111,112); A DISPLACEMENT CONTROL PART (120) IN THE BODY, THE DISPLACEMENT CONTROL PART CONTAINING THE THERMAL EXPANSION MATERIAL (125) AND DISPLACED TOWARD THE OUTLET PORT (112) WHEN THE THERMAL EXPANSION MATERIAL (125) EXPANDS, THEREBY REGULATING A DEGREE OF OPENING OF THE OUTLET PORT (112); AND A HEATER (131) FOR HEATING THE THERMAL EXPANSION MATERIAL (125) WITHIN THE DISPLACEMENT CONTROL PART. THE DISPLACEMENT CONTROL PART INCLUDES A CONTAINER (121) CONTAINING THE THERMAL EXPANSION MATERIAL (125), THE CONTAINER BEING COUPLED TO THE BODY (110) AND AN EXPANSION PLATE (122) FOR REGULATING THEDEGREE OF OPENING OF THE OUTLET PORT (112) BY BEING EXPANDED IN ACCORDANCE WITH AN EXPANSION OF THE THERMAL EXPANSION MATERIAL (125), THE EXPANSION PLATE (122) BEING HERMETICALLY COUPLED TO THE CONTAINER (121).
