<P>PROBLEM TO BE SOLVED: To provide a temperature response valve which can surely remove foreign matter sticking to a valve seat member and a valve stem. <P>SOLUTION: An inlet 5, a valve chest 4 and an outlet 7 are formed of a body 1 and a cover 2. The valve seat member 3 having a valve port 10 is arranged for communicating a lower part of the valve chest 4 with the outlet 7 side. The valve stem 13 for opening-closing the valve port 10 is arranged in the valve chest 4. A temperature sensing member 12 is installed on the outer periphery of the valve stem 13. An ultraviolet radiation lamp attaching-detaching seat 14 is arranged in a bottom part of the valve chest 4, and an ultraviolet radiation lamp 15 is detachably installed. Surfaces of the valve seat member 3 and the valve stem 13 are coated with a photocatalyst. When the foreign matter such as refuse is clogged in the valve port 10, the foreign matter of tip parts of the valve stem 13 and the valve seat member 3 and the valve port 10 can be surely decomposed and cleaned by installing the ultraviolet radiation lamp 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
