PURPOSE: A device for sealing a hot water pipe with an electric heating wire and controlling the pressure of the hot water pipe is provided to prevent water in the hot water pipe from leaking from a hit water pipe by attaching projections to the inner surface of the hot water pipe. CONSTITUTION: A device for sealing a hot water pipe with an electric heating wire and controlling the pressure of the hot water pipe(20) comprises a pressure regulator(60), a spring(50), a closing cap(40), a closing unit(80), and a fid(70). The pressure regulator is supported by the spring. The spring is supported by the closing cap to prevent the spring from being separated from the hot water pipe. The closing cap is screwed on a pipe nut(30). The closing unit is embedded in the front end of the hot water pipe, and comprises a heating wire(11). The sills of the closing unit are hung on the inner side of the fid. The projections(83) of the closing unit are exposed to the outside of the fid through a through hole(71). The fid is screwed on the pipe nut to prevent the closing unit from being separated from the hot water pipe. |
