고온 및 고압 가스관용 관이음 장치{High temperature and high tension gas usual pipe joint system}High temperature and high tension gas usual pipe joint system

본 고안은 고온 및 고압 가스관용 관이음 장치에 관한 것이다.The present invention relates to a pipe fitting for high temperature and high pressure gas pipe.

상세하게 본 발명은, 고온/고압으로 가스가 관내를 통과할 때 관 연결지점에서 가스와 화기의 누수를 방지하도록 하고, 가스와 화기에 의해 실링구성이 전혀 소진됨이 없도록 한 고온 및 고압 가스관용 관이음 장치에 관한 것이다.In detail, the present invention is a high temperature and high pressure gas pipe for preventing the leakage of gas and fire at the pipe connection point when the gas passes through the pipe at high temperature / high pressure, so that the sealing configuration is not exhausted by the gas and fire at all It relates to a pipe joint device.

보일러, 냉온수기 등에는 연소 후 발생되는 폐가스를 배출하기 위한 파이프 라인이 형성된다. 이와 같은 파이프 라인은 고온 및 고압에 견딜 수 있도록 통상 이중관으로 이루어지며, 보일러, 냉온수기 등에서 배출된 폐가스를 외부로 유도하기 위한 길이를 감안하여 대체로 2이상의 관을 연결하고, 이들 관의 연결지점에 관이음 장치를 결합하게 된다. 이와 같은 관이음 장치는 관의 연결지점에서 폐가스 및 화기가 유출됨을 방지하기 위한 실링기능을 갖추게 된다.Boilers, hot and cold water heaters, etc. are formed with a pipeline for discharging the waste gas generated after combustion. Such pipelines are usually composed of double pipes to withstand high and high pressures, and in general, two or more pipes are connected in consideration of the length for guiding the waste gas discharged from the boiler and the hot and cold water heater to the outside, and the pipes are connected to the connection points of these pipes. Combine the joints. Such a pipe joint device is equipped with a sealing function to prevent the waste gas and the fire outflow from the connection point of the pipe.

도 1은 상기와 같은 종래의 관이음 장치의 사시도이다.1 is a perspective view of a conventional pipe joint apparatus as described above.

도면을 참조하면, 종래 관이음 장치는 관(P)의 연결지점에서 관(P)의 상호 접촉지점에 밴드형태로 둘러져 결합된다. 이때, 상기 관(P)은 상호간의 접촉면적을 확장시키기 위해 외부로 확장 절곡시킨 플랜지(1)를 갖도록 형성된다.Referring to the drawings, the conventional pipe fitting device is coupled to the surrounding points of the pipe (P) in the form of a band at the connection point of the pipe (P). At this time, the pipe (P) is formed to have a flange (1) extended and bent to the outside to expand the contact area between each other.

이러한, 관(P)의 연결지점은 외주면에 플랜지(1)가 돌출된 형태를 유지하게 되며, 관이음 장치가 돌출된 플랜지(1) 형태를 감안하여 대략 "V"형태의 절곡부(2)가 형성된다. 또한, 상기 관이음 장치는 밴드형태의 일측이 개방되고, 개방된 지점에 그 내주 직경을 축소시켜 결합력을 부여하기 위한 체결부(3)가 형성되어 구성된다. The connection point of the pipe (P) is to maintain the shape of the flange (1) protruding on the outer peripheral surface, the bent portion (2) of approximately "V" shape in view of the flange (1) shape protruding pipe joint device Is formed. In addition, the pipe joint device is configured to have one side of the band shape is open, the fastening portion 3 for imparting a coupling force by reducing the inner circumference diameter at the open point.

특히, 상기와 같은 관이음 장치는 전술한 실링기능을 갖추기 위해 도 2와 같이 절곡부(2)의 내측에 실리콘 등의 합성수지로 된 실링재(4)를 충진하여 구성된다. 이와 같은 실링재(4)의 충진은 관(P)의 연결지점 틈새로 폐가스 및 화기가 관이음 장치와 관(P)의 외주면 사이의 미세 틈새로 유출되는 현상을 방지하게 된다.In particular, the pipe joint device as described above is configured to fill the sealing member 4 made of synthetic resin such as silicon inside the bent portion 2 as shown in FIG. The filling of the sealing material 4 prevents the phenomenon that the waste gas and the fire gas flow out into the fine gap between the pipe joint device and the outer circumferential surface of the pipe P as a gap between the connection points of the pipe P.

상기와 같은 실링기능을 갖는 관이음 장치는 보일러, 냉온수기 등과 같이 폐가스의 배기압력이 낮고, 온도가 대략 120℃이하일 경우 폐가스의 배출 및 실링기능에 문제가 발생되지 않지만, 최근 관이음 장치는 가스터빈 발전기 등에 적용되어 이 발전기에서 생성되는 고압, 고온의 폐가스가 진행될 때, 그 압력과 화기에 의해 실링재(4)가 타거나 녹아 소진되는 경우가 발생된다.Pipe fittings having a sealing function as described above has a low exhaust pressure of the waste gas, such as boilers, cold water heaters, etc., when the temperature is about 120 ℃ or less does not cause a problem in the discharge and sealing function of the waste gas, but recent pipe fittings are gas turbine When the high-pressure, high-temperature waste gas generated in the generator is applied to the generator, the sealing material 4 burns or melts and burns out due to the pressure and the fire.

이러한 실링재(4)의 소진에 의해 관(P)의 연결지점에서 실링기능이 수행되지 않게 됨은 당연하며, 실링재(4)가 소진된 관(P)의 연결지점으로 폐가스 및 화기가 쉽게 유출되어 화재의 위험성 및 인근 작업자의 안전사고 등의 문제점이 노출된다.It is natural that the sealing function is not performed at the connection point of the pipe P due to the exhaustion of the sealing material 4, and the waste gas and the fire are easily leaked to the connection point of the pipe P where the sealing material 4 is exhausted. The risks of problems and safety accidents of nearby workers are exposed.

The band combiner 10 is coupled to the outer peripheral surface of the connection point of the pipe (P). Such a band assembly 10 is formed with a bent portion 11 protruding outward corresponding to the shape of the flange (1) formed at the pipe (P) connection point described above. At this time, the bent portion 11 is formed in a cross-sectional shape of approximately "V" shape.

또한, 상기 밴드결합체(10)는 관(P)의 연결지점 외주면에 결합되어 압착되며 결합되기 위해 일측이 개방되고, 개방된 양단에 볼트(12) 등의 체결수단에 의해 구성된 체결부(13)가 갖추어진다.In addition, the band coupling body 10 is coupled to the outer peripheral surface of the connection point of the pipe (P), one side is open to be coupled, the fastening portion 13 is formed by a fastening means such as bolts 12 on both ends of the open Is equipped.

In particular, the sealing band 20 is bent to correspond to the form in which the flange (1) of the pipe (P) connection point protrudes, the cross-section is formed in a "U" shape, the inner surface of the flange (1) It is configured to be in contact with the outer surface of the flange (1) upon completion of the fastening.

보다 구체적으로, 상기 실링밴드(20)는 밀착부(21)와, 탄력부(22)로 이루어진다. More specifically, the sealing band 20 is made of an adhesive portion 21, the elastic portion 22.

상기 밀착부(21)는 밴드결합체(10)의 절곡부(11) 내측에 구비되어 관(P)의 플랜지(1) 외면과 대면접촉되게, 즉 플랜지(1) 외측에 둘러지도록 배치되어 그 내주면이 플랜지(1) 외면과 면접촉되도록 한 구성이다. 즉, 상기 밀착부(21)는 도면상 단면이 "U"형태로 양측 내벽면이 플랜지(1)의 외측면과 접촉되도록 한 구성이다.The close contact portion 21 is provided inside the bent portion 11 of the band assembly 10 to be in contact with the outer surface of the flange (1) of the pipe (P), that is to be enclosed outside the flange (1) to the inner peripheral surface This flange 1 is configured to be in surface contact with the outer surface. That is, the close contact portion 21 is configured such that both inner wall surfaces in contact with the outer surface of the flange 1 in the form of a cross section "U" in the drawing.

At this time, when the band coupling body 10 is compressed by the fastening of the fastening part 13, the close contact part 21 is strongly pressed against the flange 1 by the end of the close contact part 21 and the close contact part 21. The sealing between the flanges 1 will be implemented.
