Title:
HIGH TEMPERATURE GAS BACK-FLOW PREVENTING FLOAT TYPE CHECK VALVE
Document Type and Number:
Japanese Patent JP2016118219
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high temperature gas back-flow preventing float type check valve for preventing back-flow of liquid and high temperature gas.SOLUTION: In a high temperature gas back-flow preventing float type check valve 100, when liquid is stored in an internal space S100, a part of a float 106 is fitted to an inflow passage W102. Accordingly, the liquid back-flowing into the internal space S100 is prevented from back-flowing into an inflow pipe T2 through the inflow passage W102. Further, when high temperature gas is stored in the internal space S100 and a temperature in the internal space S100 reaches a prescribed value, a bimetal spring 107 is expanded, and a part of the float 106 is fitted to the inflow passage W102. Accordingly, the high temperature gas back-flowing into the internal space S100 is prevented from back-flowing into the inflow pipe T2 through the inflow passage W102.SELECTED DRAWING: Figure 1
