More Information
Summary:A valve for controlling a flow rate is provided to maintain consistency of operation even when the valve is used for a long time. A valve for controlling a flow rate includes a valve housing(10), a fixing pipe(20), a hollow moving pipe, a temperature responsive spring(40), and a compression spring(50). The valve housing has an inlet port(11) and an outlet port(12). The fixing pipe is fixed in the valve housing, and has a discharge port in communication with a discharge port of the valve housing. The hollow moving pipe is inserted into the fixing pipe to be slidably supported along a longitudinal direction of the fixing pipe. The temperature responsive spring is formed of a shape memory alloy to be extended when it is in contact with a temperature higher than a first temperature and shrunk when it is in contact with a temperature lower than a second temperature. The compression spring is installed at a rear end of the moving pipe.
