Heat conduction along and through the line of a nonambient temperature liquid system is deterred by a thermal barrier having insulative stop and seat components interengaged for thermally isolating the liquid on one side of the barrier from the liquid on the other side of the barrier when the liquid within the line is stagnant. The barrier automatically opens to permit liquid flow through the line and closes to thermally isolate the liquid when the flow is interrupted, i.e. the liquid flow within the line is substantially unimpeded by the thermal barrier...
A thermal barrier comprising a hollow body forming a liquid duct having a liquid inlet and a liquid outlet and having a seat between said liquid inlet and said liquid outlet; a stop engageable with said seat to obstruct said duct, said stop being of substantial extent lengthwise of said duct and engageable with said seat over a considerable area and said body and said stop being constructed of thermal insulating plastic material having such a low thermal conductivity that when said stop is in engagement with said seat a substantial extent of such materia...
