본 발명은 전열선 내장형 온수관의 밀폐 및 압력조절장치에 관한 것으로, 더욱 바람직하게는 온수관내의 팽창압력이 상승해도 온수관 내부의 후단부측에 장착된 압력유지 조절장치의 밀폐부재가 탄발스프링의 탄성력에 의해 이동하면서 압력을 조절하고, 또 실리콘으로 형성된 밀폐수단이 온수관의 내부면과 밀착되게 굴곡부를 형성함과 동시에 밀폐수단의 선단부를 배관너트와 연결된 피딩의 외부로 노출되게 형성함으로써 온수관과 밀폐수단을 긴밀하게 밀폐할 수 있도록 하기 위한 것이다.The present invention relates to a sealing and pressure regulating device of a heating wire built-in hot water pipe, and more preferably, even if the expansion pressure in the hot water pipe is increased, the sealing member of the pressure holding control device mounted on the rear end side of the hot water pipe is formed of a carbon spring. By adjusting the pressure while moving by elastic force, and forming the bent portion in close contact with the inner surface of the hot water pipe while forming the front end of the sealing means exposed to the outside of the feeding connected to the piping nut And to close the sealing means tightly.

일반적으로 전열선이 내장된 난방용 온수관의 경우, 온수관의 내부에는 열매(熱媒) 또는 물을 충진하고, 전원과 연결된 전열선이 온수관의 길이방향으로 내장되어 열매 또는 물을 가열하게 되고 이로 인해 실내의 난방을 가능하게 한다. In general, in the case of a heating hot water pipe with a heating wire, the inside of the hot water pipe is filled with fruit or water, and a heating wire connected to the power source is heated in the longitudinal direction of the hot water pipe to heat the fruit or water. Enable the heating of the room.

이러한 온수관 및 전열선의 연결부를 밀폐하기 위한 종래의 기술로는 실용신안 출원번호 제 2005-0035441호의 ' 전열선이 삽입된 온수관의 이중 밀폐수단'에 제안되어 있듯이 전열선이 삽입되어 있는 온수관과, 연결편 내측의 관통공과, 너트체결부와, 배관체결부와, 상기 너트체결부와 배관체결부의 요홈과, 상기 너트체결부의 돌출편과, 상기 온수관의 링와셔와 너트와, 캡너트와, 밀봉캡으로 구성되어 있다.As a conventional technique for sealing the connection portion of the hot water pipe and the heating wire, the hot water pipe with the heating wire inserted therein, as proposed in the Utility Model Application No. 2005-0035441 'double sealing means of the hot water pipe inserted with the heating wire'; Through hole inside the connecting piece, nut connection part, pipe connection part, groove of the nut connection part and pipe connection part, protruding piece of the nut connection part, ring washer and nut of the hot water pipe, cap nut and sealing It consists of a cap.

그러나, 상기 선 고안은 밀봉캡이 연결편과 캡너트가 체결되면서 누설부위 및 전열선과 탄력적으로 압착되는데, 캡너트의 체결력이 약할 경우 전열선 및 결합부위의 밀착력이 미흡하여서 난방수가 누설되거나 오히려, 과다할 경우 압착된 부위 및 주위가 상대적으로 취약하여서 쉽게 파손되는 문제점이 있었다.However, in the wire design, the sealing cap is elastically crimped with the leakage portion and the heating wire as the connecting piece and the cap nut are fastened. When the cap nut is weakly fastened, the heating water leaks due to insufficient adhesion between the heating wire and the coupling part. In the case of the crimped portion and the surrounding is relatively fragile, there was a problem that is easily broken.

그리고, 상기 밀봉캡이 탄성력을 가지는 부재로 이루어져 좁은 통공을 통해 전열선을 통과시키는 과정이 까다롭고, 전열선을 삽입하는 과정에서 밀봉캡 및 통공이 손상되며, 작업공정이 번거로움에 따라 작업시간이 지연되는 문제점이 있었다.In addition, the sealing cap is made of a member having an elastic force is difficult to pass the heating wire through the narrow hole, the sealing cap and the hole is damaged in the process of inserting the heating wire, work time is delayed due to the cumbersome work process There was a problem.

또한, 상기 밀봉캡이 전열선의 열에 취약하여서, 전열에 의해 변형 및 부식되거나 녹는 등 손상됨으로써, 전열선과의 밀착부위가 헐거워지고 누수현상이 발생되어서 방수의 역할을 상실하는 단점이 있었다. 이는, 잦은 부품의 교환으로 인한 보수시간 및 관리비용 또한 과다하게 소요되는 경제적인 단점을 초래하였다.In addition, the sealing cap is vulnerable to the heat of the heating wire, deformed by the heat transfer, corrosion, or damage, such as damage, loose contact with the heating wire has a disadvantage that the water leakage phenomenon occurs to lose the role of waterproof. This has resulted in an economic disadvantage that the maintenance time and management costs due to frequent replacement of parts are also excessive.

이와 같은 문제점을 개선하고자, 특허출원 제10-2007-34922호'전열선 내장형 온수관의 밀폐수단'와 실용신안출원 제20-2007-5850호 '온수관 전열선의 결합구조'가 개시되어 있다.In order to improve such a problem, Patent Application No. 10-2007-34922 'sealing means of the hot water heater-type hot water pipe' and Utility Model Application No. 20-2007-5850 'combined structure of the hot water pipe heating wire' is disclosed.
