SOLENOID VALVE AND PRESSURE SWITCH

摘要

PROBLEM TO BE SOLVED: To provide a solenoid valve and a pressure switch reducing influence of heat on mechanical parts in brazing performed when built in a refrigerating cycle and improving a fall of mass productivity in cooling due to conventional submergence and wet rag.

SOLUTION: Beading is applied to at least one part of a copper pipe near the mechanical parts 10 of a solenoid valve 3 and a pressure switch 7 which are components of a refrigerating cycle of an air conditioner or a heat pump water heater. The influence of heat on the mechanical part in brazing when the mechanical part 10 of the pressure switch 7 is built in the refrigerating cycle is thereby reduced to improve mass productivity in cooling with conventional submergence and wet rag.
