As the piston 72 inside the pressure regulator 70 descends to absorb the static pressure inside the hot water pipe 1, on the contrary, negative pressure is generated inside the hot water pipe 1 by cooling the heat medium 4. When the piston 72 inside the pressure regulator 70 rises and absorbs the negative pressure inside the hot water pipe 1, the pressure regulator 70 keeps the pressure inside the hot water pipe 1 always constant.

즉, 상기와 같이 연결부재(40)에 압력조절기(70)를 구성함으로써 열매체(4)의 가열 또는 냉각에 의한 온수관(1) 내부의 압력변화에 따라 일일이 열매체(4)를 추출 또는 주입할 필요없이, 온수관(1)과 내통 되도록 설치된 상기 압력조절기(70)가 열매체(4)의 열팽창 및 열수축에 따른 온수관(1) 내부의 압력변화를 수용함으로써 온수관(1) 내부의 압력을 항상 일정하게 유지하여 준다.That is, by configuring the pressure regulator 70 in the connecting member 40 as described above, the heating medium 4 can be extracted or injected one by one according to the pressure change inside the hot water pipe 1 by the heating or cooling of the heating medium 4. Without the need, the pressure regulator 70 installed so as to be in the inner tube and the hot water pipe 1 accommodates the pressure change in the hot water pipe 1 due to thermal expansion and thermal contraction of the heat medium 4 so as to increase the pressure inside the hot water pipe 1. Keep it constant at all times.

도 5는 본 발명의 다른 실시예에 의한 전기보일러의 온수관 단부 밀폐장치를 나타낸 단면도로서, 도 3에 도시된 연결부재(40)와 압력조절기(70)의 사이에 "T"형의 유량조절부재(50)를 더 결합하여 구성된다.FIG. 5 is a cross-sectional view illustrating a hot water pipe end sealing device of an electric boiler according to another embodiment of the present invention, wherein a flow rate control of a “T” type is provided between the connecting member 40 and the pressure regulator 70 shown in FIG. 3. It is comprised by combining the member 50 further.

상기 유량조절부재(50)는 나사가 형성된 일측에 가이드홈(53)이 형성된 밀봉재(51)와 상기 밀봉재(51)와 같은 위치에 구멍이 형성된 부시(52)를 삽입하고, 너트(54)를 체결함으로써 구성되는데, 상기 너트(54)를 체결할 때 부시(52)가 밀봉재(51)를 강하게 압착함으로써 밀봉재(51)가 단단히 고정되도록 하고, 부시(52)는 너트(54)를 체결할 때 너트(54)와 밀봉재(51) 사이의 마찰을 감소시켜 밀봉재(51)가 비틀림 없이 단부를 밀폐하도록 한다.The flow rate adjusting member 50 inserts a seal member 51 having a guide groove 53 formed on one side of a screw formed therein and a bush 52 having a hole formed at the same position as the seal member 51, and inserts a nut 54. When the nut 54 is tightened, the bush 52 presses the seal 51 hard so that the seal 51 is firmly fixed, and the bush 52 tightens the nut 54. The friction between the nut 54 and the seal 51 is reduced to allow the seal 51 to seal the end without twisting.

상기와 같이 구성된 유량조절부재(50)는 온수관(1) 내부와 연통된 연결부재(40)에 체결되기 때문에 유량조절부재(50)를 통해 온수관(1) 내부로 열매체(4)를 보충하거나 추출할 수 있고, 상기 유량조절부재(50)를 통해 온수관(1) 내부에 존재하는 공기를 추출할 수 있다.Since the flow regulating member 50 configured as described above is fastened to the connection member 40 communicating with the inside of the hot water pipe 1, the heat medium 4 is replenished into the hot water pipe 1 through the flow regulating member 50. Or it may be extracted, the air existing in the hot water pipe (1) through the flow control member 50 can be extracted.

도 5의 전원선(6)에 전기를 인가하면 온수관(1)에 내재된 전열선(3)이 발열하게 되고, 온수관(1) 내부에 충전된 열매체(4)가 가열됨으로써 상기 온수관(1)이 매립된 곳의 온도를 상승시킨다.When electric power is applied to the power line 6 of FIG. 5, the heating wire 3 embedded in the hot water pipe 1 generates heat, and the heating medium 4 filled in the hot water pipe 1 is heated to heat the water pipe ( 1) Increase the temperature of the landfill.

이때, 전열선(3)에 의해 가열되는 열매체(4)의 온도상승과 비례하여 열매체(4)가 팽창하게 되어 온수관(1) 내부에 정압이 발생하는데, 상기 온수관(1) 내부의 정압은 압력조절기(70)가 흡수하여 온수관(1) 내부의 압력을 일정하게 유지한다.At this time, the heat medium 4 expands in proportion to the temperature rise of the heat medium 4 heated by the heating wire 3, and a positive pressure is generated inside the hot water pipe 1, and the positive pressure inside the hot water pipe 1 is The pressure regulator 70 absorbs and maintains a constant pressure inside the hot water pipe (1).

그러나, 전열선(3)에 의한 가열로 인해 열매체(4)의 온도가 이상적으로 상승 하여 열매체(4)의 팽창량이 클 경우, 즉, 압력조절기(70)의 압력조절 수용량보다 온수관(1) 내부의 열매체(4)의 열팽창량이 클 경우에는 상기 유량조절부재(50)에 구성된 부시(52)의 구멍에 주사기 바늘을 삽입하여 밀봉재(51)를 관통하여서 온수관(1)과 연통된 연결부재(40)의 내부에 있는 열매체(4)를 추출함으로써 온수관(1) 내부의 압력을 감압한다.However, when the temperature of the heating medium 4 ideally rises due to the heating by the heating wire 3, and the expansion amount of the heating medium 4 is large, that is, inside the hot water pipe 1 than the pressure regulating capacity of the pressure regulator 70. When the thermal expansion amount of the heat medium 4 is large, a syringe needle is inserted into the hole of the bush 52 formed in the flow regulating member 50 to penetrate the sealing material 51 to communicate with the hot water pipe 1 ( The pressure inside the hot water pipe 1 is reduced by extracting the heat medium 4 in the inside of 40.

또한, 상기 온수관(1)의 냉각에 의한 열매체(4)의 수축량이 클 경우, 즉, 압력조절기(70)의 압력조절 수용량보다 온수관(1) 내부의 열매체(4)의 열수축량이 클 경우에도 주사기 바늘을 이용하여서 상기와 같은 방법으로 온수관(1) 내부로 열매체(4)를 주입하여 열매체(4)를 보충할 수 있다.In addition, when the shrinkage of the heat medium (4) by the cooling of the hot water pipe (1) is large, that is, the heat shrinkage amount of the heat medium (4) inside the hot water pipe (1) larger than the pressure regulating capacity of the pressure regulator (70). In addition, by using a syringe needle inject the heat medium (4) into the hot water pipe (1) in the same manner as described above can replenish the heat medium (4).

또한, 상기와 같은 방법으로 온수관(1) 내부에 존재하는 공기를 상기 유량조절부재(50)를 통하여 찬 공기를 제거할 수 있다.In addition, cold air may be removed from the air existing in the hot water pipe 1 through the flow regulating member 50 in the same manner as described above.

결국, 본 발명의 기술적 핵심은 전열선(3)에 의해 가열되는 열매체(4)의 팽창에 의해 온수관(1) 내부에 발생하는 정압과, 열매체(4)의 냉각에 의한 수축으로 온수관(1) 내부에 발생하는 부압을 압력조절기(70)가 흡수하여 온수관(1) 내부의 압력을 항상 일정하게 유지할 수 있고, 또한, 유량조절부재(50)를 이용하여 온수관(1) 내부로 열매체(4)를 보충하거나 추출할 수 있고, 온수관(1) 내부에 발생된 공기를 상기 유량조절부재(50)를 이용하여 제거할 수 있는 것이다.As a result, the technical core of the present invention is a positive pressure generated inside the hot water pipe 1 by the expansion of the heat medium 4 heated by the heating wire 3, and the hot water pipe 1 due to the shrinkage caused by the cooling of the heat medium 4. The pressure regulator 70 absorbs the negative pressure generated therein so that the pressure inside the hot water pipe 1 can be kept constant at all times, and the heat medium is introduced into the hot water pipe 1 using the flow regulating member 50. (4) can be supplemented or extracted, it is possible to remove the air generated inside the hot water pipe (1) using the flow rate control member (50).
