<p><P>PROBLEM TO BE SOLVED: To provide a heat insulation cover rich in versatility installable in several kinds of steam traps different in an outer diameter of a cover body. <P>SOLUTION: This cap type heat insulation cover 1 crowns so as to form an air layer outside a cover body which internally installs a driving part for operating a valve element provided in the steam trap, and is provided with a clip 7 for diametrically freely expanding and contracting by suspending a plurality of band plate pieces 8, 8a, etc. at an equal interval on the circumference set in a ceiling 1a inside the cover 1 so as to be elastically energized in the centripetal direction. In the band plate pieces 8, 8a, etc., a plurality of steps 9 and 9a fixed to the upper edge of the respective covers by elastically expansively opening so as to correspond onto the same circumference as the respective outer diameters of a plurality of cover bodies different in the outer diameter, are bent and formed in a stair shape from a height position at a predetermined interval from the ceiling 1a. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
