ABSTRACT:
A new temperature-sensitive valve for handling liquids includes a housing having a valve seat and a valving member mounted for movement from a flow-permitting first position spaced from the seat to a flow-blocking second position against the seat. A latching mechanism is coupled to the valving member for retaining such member in the first position when the temperature of the liquid is below a shutoff temperature. A temperature-sensitive device is mounted in the valve body and has an actuator coupled to the latching mechanism. The valve body has a chamber containing the sensing portion of the temperature-sensitive device and also has flow apertures positioned so that when the valve is open, liquid flows across and is in contact with the sensing portion for excellent heat transfer and quick response. The latching mechanism is released and the valving member moves to the second position when the temperature of the liquid is above the shutoff temperature. Sensitive analyzing instruments are thereby protected from exposure to liquids, the temperature of which may be damaging to the instruments.
