Temperature sensing tube for expansion valve

To provide a temperature sensing tube for an expansion valve in which a hunting can be prevented by slowing of a temperature reaction rate of an expansion valve, a ceramic sintered member serving as a heat transfer delay member (3) in a temperature sensing tube (1) is fixed so as not to directly con...

Beschreibung
Zusammenfassung:	To provide a temperature sensing tube for an expansion valve in which a hunting can be prevented by slowing of a temperature reaction rate of an expansion valve, a ceramic sintered member serving as a heat transfer delay member (3) in a temperature sensing tube (1) is fixed so as not to directly contact with a tubular member (2) by fixing springs (4, 4) provided at both end portions (13, 13), whereby a heat transfer from the tubular member (2) to the ceramic sintered member becomes slow, temperature is not transferred from a mated piping directly via the tubular member, whichever outer surface of the temperature sensing tube 1 contacts with the piping, and a reaction rate with respect to a temperature rise of the expansion valve can be made slow.
