TEMPERATURE-RESPONSIVE FLUID FLOW CONTROL APPARATUS

摘要

The temperature-responsive fluid flow control apparatus of the present invention comprises: a housing installed between the inlet and the outlet of a fluid tube in which a fluid flows; a valve block installed inside the housing to allow inflow of the flowing fluid into the housing and to discharge part of the flowing fluid to the outside according to the change in the internal pressure; and a temperature-responsive device for generating a pressure difference in the valve block according to the temperature change of the temperature-responsive fluid filled therein. The temperature-responsive fluid flow control apparatus prevents the fluid flowing tube from freezing by discharging part of the fluid flowing in the housing to the outside, when the temperature of the temperature-responsive fluid reaches a preset temperature as the external temperature drops.
