Description
본 발명은 이중관의 신축이음장치에 관한 것으로, 특히,신축이음장치에서 분기관이 분기되고, 누설유체압에 따라 배출이 이루어짐과 동시에 육안확인구를 갖이며,사후 조인트 누설보수시 외부배관을 제거 및 분해 하지 않고 파우더 패킹을 투입하여 간단히 보수되는 단열 이중관 신축 조인트이음 장치에 관한 것이다.The present invention relates to a double pipe expansion joint device, in particular, the branch pipe is branched from the expansion joint device, the discharge is made according to the leakage fluid pressure and has a visual confirmation port, and removes the external pipe during the post-joint leakage repair And it relates to a thermal insulation double pipe expansion joint joint device that is simply repaired by putting powder packing without disassembly.
일반적으로 열병합발전소 및 각종 산업플랜트에서 중온수, 스팀등 고온의 유체를 사용처까지 장거리 수송을 하기 위해서는 지하배관을 설치하고 있으나, 외부 온도 및 수송중인 유체의 자체온도 변화로 배관의 선 팽창계수에 의해 배관의 신축이 발생하게 된다.In general, underground piping is installed for long distance transportation of high temperature fluid such as heavy temperature water and steam in cogeneration power plants and various industrial plants.However, due to the linear expansion coefficient of the pipe due to the change in the external temperature and the temperature of the fluid being transported. Expansion of the pipe occurs.
장거리 배관시 단열 이중 배관의 구성은 내부배관 보호용 외부배관과 유체를 송기하는 내부배관으로 구성되며 내부배관은 유체 온도차에 의하여 배관이 수축 신축을 흡수할 수 있는 신축이음관이 부착된다. 이러한 신축이음관은 내부배관의 신축 흡수량을 흡수하기 위하여 다수 연결되고, 외관과 내관사이 공간에는 보온재인 단열재를 충진하고 단열재 사이에는 조인트 누설시 누설을 감지할 수 있는 누수감지선을 삽입하게 된다.In the case of long distance piping, the double insulation pipe consists of the outer pipe for protecting the inner pipe and the inner pipe for sending the fluid. The inner pipe is equipped with the expansion pipe which can absorb the shrinkage by the fluid temperature difference. These expansion joints are connected in order to absorb the amount of expansion and absorption of the inner pipe, the space between the outer and the inner tube is filled with insulation, which is a thermal insulation material, and the leakage detection wire that can detect the leakage in the joint leakage between the insulation.
종래로 부터 내외관의 이중배관을 구성하고, 그 사이의 공간상에 단열재를 충진하여 내외부간의 단열을 기하며, 이와같은 내외관사이에 신축이음수단을 강구함에 있어 그 신축부의 실링부분을 처리하기 위한 패킹실린더를 구현한 것이 등록제260567호 실용신안등으로 알려져 있었다.Conventionally, it constitutes a double pipe of inner and outer tubes, fills the insulating material in the space therebetween to insulate the inside and the outside, and in order to obtain the expansion joint means between the inside and the outside packing for processing the sealing part of the expansion part. The implementation of the cylinder was known as Utility Model No. 260567.
이 종래의 신축이음구조는 조인트챔버표면에서 발생되는 열을 차단하기 위하여 외통과 조인트 챔버사이에 전고정판과 후고정판을 고정시키고 그 사이로 단열재를 진공 공간 형성없이 단열재를 주입하고 단열재 사이로 누수감지선을 설치하여 신축 조인트 누수유무 만을 감지하는 것이며, 단열재를 주입하기 위한 단열재 주입구를 내외관을 괸통하여 설치하고, 누수감지선도 설치하여 슬라이드면으로 누출된 유체를 단열재 충진공간상에서 감지한 뒤 외관의 패킹실린더를 통하여 패킹주입볼트를 통하여 파우다패킹을 주입하여 누수를 차단할 수 있는 구조로서 지상 혹은 지하에서 배관 연결부인 조인트의 외관을 단열재로 에워싸서 조인트 내부에 흐르는 고온, 고압의 유체의 열이 외부로 방출되지 않게 함은 물론 매설배관 경우 토질의 온도 등으로 조인트 단열보호외부재의 표면 접촉시 온도차에 의한 열손실 방지와 지상으로 방출 될수 있는 열 발생을 차단하고, 단열재 충진공간에 누수감지선을 설치한 매립형 보온카바 슬라이드 조인트이다.In this conventional expansion joint structure, the front fixing plate and the rear fixing plate are fixed between the outer cylinder and the joint chamber to block the heat generated from the joint chamber surface, and the insulating material is injected into the insulating material without forming a vacuum space therebetween, and a leak detection line is inserted between the insulating materials. It installs and detects only the expansion joint leakage, and installs the insulator injection hole for insulating material through the inner and outer pipes, and also installs the leak detection line to detect the fluid leaked on the slide surface in the insulator filling space and It is a structure that can block leakage by injecting powder packing through packing injection bolt through the insulation of the joint which is the pipe connection on the ground or underground so that the heat of high temperature and high pressure fluid flowing inside the joint is not released to the outside. In the case of buried piping, This is a buried insulation cover slide joint that prevents heat loss due to temperature difference and prevents heat generation that can be released to the ground when the surface of the joint insulation protection outer member contacts the surface, and installs a leak detection line in the insulation filling space.
그러나 이와같은 등록실용신안등의 복합배관의 조인트구조는 다음과 같은 몇몇 문제점이 있다.However, such a joint structure of a composite pipe such as a utility model for registration has some problems as follows.
첫째, 상기한 바와같이 외관과 내관사이의 공간에는 보온재인 단열재를 충진하고 단열재 사이에 조인트 누설시 누설을 감지할 수 있는 누수감지선을 삽입하였으나 현실적으로 유체누설 구간을 파악하기 어려운 문제점이 있다. First, as described above, a space between the exterior and the inner tube is filled with a heat insulating material, and a leak detection line is inserted between the heat insulating materials to detect leakage when the joint is leaked.
그 이유는 신축이음관 자체 유체누설이나 유체를송기하는 배관자체의 용접부위 유체누설시 육안누설 감지구가 없으므로 감지선으로부터 누수감지는 되고 있으나 유체가 내관과 외관 사이의 단열재 공간인 장거리 전 배관에 채워지기 때문에 다수 신축이음관의 어느 부분에서 유체누설이 발생하는 지 장거리 배관중 어느 용접 부위에서 유체누설이 이루어지는 지를 구분하여 파악하기 힘들다.The reason for this is that the expansion joint itself has a fluid leak or a welding part of the pipe itself that transmits the fluid, so there is no visual leak detection port, so leakage is detected from the detection line. Because of the filling, it is difficult to know which fluid leakage occurs in a large number of expansion joints and which welding site is used for long distance piping.
둘째, 유체누설되는 신축이음관의 부위를 발견하더라도 신축이음부의 유체누설부위를 차단조치하여야 하나, 어느 신축이음부인지 파악이 어려워 확인이 될때까지 장거리 배관망 전체 시스템을 가동정지 해야하며, 신축이음 조치후 재가동시 외부배관과 내부배관 사이의 단열재가 유체로 젖어있어 감지선이 오동작하므로 젖어있는 단열재를 건조시킨 뒤 재가동해야하는 번거로움도 있다.Second, even if a leaky expansion pipe part is found, the fluid leakage part of the expansion joint should be shut off.However, it is difficult to identify which expansion joint, so the entire system of the long-distance pipe network must be stopped until it is confirmed. When restarting after the measures, the insulation between the outer and inner pipes is wet with fluid, and the sensing line malfunctions. Therefore, it is troublesome to dry and restart the wet insulation.
셋째, 상기한 종래 신축이음구조는 배관내에서 분기관을 형성할 경우 신축이음 자체에 분기관이 없으므로 분기관의 시공이 불가능한 문제점도 있었다.Third, the conventional expansion joint structure has a problem that the construction of the branch pipe is impossible because the expansion joint itself does not have a branch pipe when forming the branch pipe in the pipe.
따라서 단열 이중관에서 외부로 방출되는 열손실을 보다 강력하게 차단하기 위하여 단열처리함과 동시에 진공을 함이 필요로 되며, 아울러 단열 이중관 에 사용된 신축이음관에 적정한 수축시 유동성을 흡수할 수 있는 수축,팽창구조가 필요로 되며, 동시에 그와 같은 신축이음시의 누설유체를 집수하고 처리하며, 확인하기 위한 단열공간과 격리된 독립적인 공간의 형성이 필요로 되며, 이 공간을 통하여 육안으로 유체누설 상황을 확인할 수 있는 신축이음관가 필요로 되어 왔다.Therefore, it is necessary to insulate and vacuum at the same time in order to more strongly block the heat loss emitted from the insulated double pipe to the outside. In addition, the shrinkage can absorb the fluidity when the proper expansion pipe is used for the insulated double pipe. The expansion structure is required, and at the same time, the formation of an independent space separate from the insulation space for collecting, treating, and confirming the leakage fluid in the expansion joint is required, and the fluid leakage through the space There has been a need for new expansion joints to identify the situation.
본 발명은 이와같은 종래 단열 이중관 방식의 신축조인트의 누수,누열 및 초기 시공성과 사후관리 문제점을 단열재외에 진공을 통하여 보온효과를 증대 시키고, 신축 조인트누설시 배관 시스템의 영향없이 간편히 유지보수할 수 있는 단열 이중관 신축이음구조를 제공하는 데에 그 목적이 있다.The present invention can increase the thermal insulation effect through the vacuum in addition to the insulation, leakage, leakage and initial construction and after-care problems of the conventional thermal insulation double pipe type expansion joint, and can be easily maintained without the influence of the piping system when expanding the expansion joint The purpose is to provide an insulating double pipe expansion joint structure.
본 발명은 단열이중 배관의 신축이음 장치를 구현함에 있어 외관과는 별도로 신축이음부에 육안 누수확인 공간을 형성하여 내관으로부터 발생된 누수상태를 외관 외부에서 파악 가능하고, 이 누수공간은 단열/진공공간에 영향을 주지않도록 하는 단열 이중관 신축이음장치를 제공하는데에도 그 목적이 있다.In the present invention, in the implementation of the expansion joint device of the double insulation pipe, it is possible to grasp the leakage state generated from the inner pipe by forming a visual leak check space in the expansion joint separately from the exterior, the leak space is insulated / Another object of the present invention is to provide an insulating double pipe expansion joint device that does not affect the vacuum space.
본 발명은 단열 이중관의 신축이음장치에 분기관이 이미 설치가능하게 형성되어 있어 분기관의 시공이 간편하게 이루어지며, 사후 누수방지 조치에 있어 해당 부분의 외관 분해 없이 간편하게 보수유지 할 수 있는 단열 이중관의 신축이음장치를 제공하는 데에도 그 목적이 있다.The present invention is the branch pipe is already formed to be installed in the expansion joint device of the heat insulating double pipe is made easy to install the branch pipe, the insulation of the double pipe that can be easily maintained without disassembly of the appearance in the post-leak prevention measures The purpose is to provide expansion joints.
본 발명은 도로지면에 위치하는 누수확인구가 일정한 압력 도달시 배수처리와 우수 및 이물질이 진동등에 의하여 유입되지 않고 누설유체가 자동 배기됨은 물론 수동개페도 가능한 단열 이중관의 신축이음 장치를 제공하는 데에 그 목적이 있다.The present invention is to provide a expansion joint device of a double-insulated double pipe that can be leaked automatically as well as manual drainage without drainage treatment and rainwater and foreign matter is not introduced by the vibration, etc. when the leak confirmation sphere located on the road surface reaches a certain pressure. Has its purpose.

본 발명의 단열이중관 신축이음장치는 내관내에 위치하는 신축이음관의 외측에 일단면을 연결하여 그 내부가 독립된 공간을 형성하면서 신축작동하는 벨로우즈관을 더 포함하는 것을 특징으로 한다. Insulating double pipe expansion joint device of the present invention is characterized in that it further comprises a bellows pipe that extends and works while connecting one end surface to the outside of the expansion joint pipe located in the inner tube to form an independent space therein.
본 발명의 단열이중관 신축이음장치의 상기한 독립공간에서 외관측으로 신축이음관의 신축작동시 발생되는 유체누설를 확인하기 위한 유체누설확인구를 수직형성함이 바람직하다.It is preferable to vertically form a fluid leakage check port for confirming the fluid leakage generated during the expansion operation of the expansion joint pipe in the above-described independent space of the insulating double tube expansion joint device of the present invention.

In the accompanying drawings, Figure 1 is a perspective view showing the appearance of the pipe is implemented the expansion joint device of the heat insulation double pipe of the present invention, Figure 2 is an exploded perspective view of the inner tube implemented the expansion joint device of the heat insulation double pipe of the present invention.
상기 도면들에 따르는 본 발명 단열이중관의 신축이음장치는 크게 원통형의 외관(100)과, 상기 외관(100)의 내측에 소정의 간격을 두고 설치되는 내관(110)과, 이 내관(110)에서 외관(100)으로 연결되는 분기관(200)과, 상기 내관(110)의 일단에 연결되는 벨로우즈관(150)과, 내관(110)의 소정위치에 일주하면서 설치되는 패킹실린더(142)로 이루어진다.The expansion joint device of the present invention heat insulation double tube according to the drawings is a large cylindrical appearance 100, the inner tube 110 which is installed at a predetermined interval inside the outer appearance 100, and in the inner tube 110 It consists of a branch pipe 200 connected to the exterior 100, a bellows pipe 150 connected to one end of the inner tube 110, and a packing cylinder 142 installed while circumventing at a predetermined position of the inner tube 110. .
이때 분기관(200)을 형성하는 내관(110)의 연장은 상기 내관(110)과 외관(100)의 간격을 유지하기 위하여 외관(100)내측에는 사각플랜지 타입의 제 1플레이트(132)를 형성하고, 내관(110)외측에는 사각플랜지 타입의 제 2플레이트(134)를 복수형성하여 체결되는 앵커구조(130)로서 이루어진다.At this time, the extension of the inner tube 110 forming the branch pipe 200 forms the first plate 132 of the rectangular flange type in the inner side of the outer tube 100 in order to maintain the interval between the inner tube 110 and the outer tube 100. In addition, the outer tube 110 is formed as an anchor structure 130 which is fastened by forming a plurality of square plates of the second plate 134.
제1,제2플레이트(132)(134)를 대응체결하는 앵커구조(130)에는 열전달차단용 가스켓이 개재된 상태에서 체결부재(136)로서 체결한다.The anchor structure 130 correspondingly fastening the first and second plates 132 and 134 is fastened as a fastening member 136 in a state where a heat transfer blocking gasket is interposed therebetween.

In addition, the exterior 100 is formed with a fluid leakage check opening 160 extending from the inner tube 110, the inlet 102 and the cap 104 for injecting the powder packing to the packing cylinder 142.
첨부 도면중 도 3은 본 발명 단열이중관의 신축이음장치가 구현된 배관의 1실시예의 단면도이고, 도 4는 본 발명 단열이중관의 신축이음장치가 구현된 배관의 측면도이다.3 is a cross-sectional view of one embodiment of a pipe in which the expansion joint device of the present invention heat insulation double pipe is implemented, and FIG. 4 is a side view of the pipe in which the expansion joint device of the heat insulation double pipe of the present invention is implemented.
상기 도면들에 의한 본 발명 단열이중관의 신축이음장치는 상기한 바와같은 내관(110)과 외관(100)사이의 공간(a)에 단열재(120)를 충진하고 동시에 소정압력의 진공을 실시한다. 상기 단열재는 폴리우레탄폼 단열재가 적당하고, 그 진공압력은 약 760mmHg가 적당하다.The expansion joint device of the present invention heat insulating double tube according to the drawings is filled with the heat insulating material 120 in the space (a) between the inner tube 110 and the exterior 100 as described above and at the same time performs a vacuum of a predetermined pressure. The heat insulating material is a polyurethane foam heat insulating material is suitable, the vacuum pressure of about 760mmHg is suitable.
특히, 상기 외관(100)에는 투입구(102)와 캡(104)을 형성하고 그 직하방의 상기 내관(110)에는 패킹실린더(142)를 설치하며, 패킹실린더(142) 하방에는 파우다패킹(141)에 의하여 그 신축이동의 틈이 강하게 실링됨과 동시에 이동이 가능한 신축이음관(140)이 밀착된다.In particular, the exterior 100 is formed in the inlet 102 and the cap 104 and the inner cylinder 110 directly below the packing cylinder 142 is installed, below the packing cylinder 142 powder packing 141 As a result, the gap of the expansion and contraction movement is strongly sealed and at the same time, the expansion and contraction pipe 140 is movable.
따라서 신축이음관(140)의 파우더패킹(141)부분과 벨로우즈관(150)에 연결된 사이는 소정의 독립적인 공간(b)을 형성한다. Therefore, between the powder packing 141 portion of the expansion joint 140 and the bellows tube 150 forms a predetermined independent space (b).
즉, 신축이음관(140)의 일단면(151)을 내관(110)에 연결된 벨로우즈관(150)의 타단에 연결함으로써 차단되고, 타단면(152)은 패킹실린더(142)에 의하여 공급된 실링부재(파우더패킹)에 의하여 틈새가 차단됨으로써 밀폐된 공간(b)을 형성하는 것이다. 이 공간(b)은 신축이음관(140)의 신축작동시 발생되는 누설유체가 모이는 곳이기도 하다. 본 발명은 이 공간(b)에 유체누설 확인구(160)가 형성되어 육안으로도 누설유체의 확인이 가능해지며, 누설유체의 제거가 가능하다. That is, it is blocked by connecting one end surface 151 of the expansion joint pipe 140 to the other end of the bellows pipe 150 connected to the inner tube 110, the other end surface 152 is a sealing supplied by the packing cylinder 142 The gap is blocked by the member (powder packing) to form a closed space b. This space (b) is also the place where the leakage fluid generated during the expansion operation of the expansion joint pipe 140 is collected. In the present invention, the fluid leakage check port 160 is formed in this space (b), so that the leaked fluid can be checked with the naked eye, and the leaked fluid can be removed.
미설명부호 170은 단열재충진공간의 누수감지선이다.Reference numeral 170 is a leak detection line of the insulation filling space.
이와같은 본 발명 단열이중관의 신축이음장치는 외관(100)의 내측과 내관(110)의 외측사이에 진공이 걸려 있으므로 그동안 내관(110)에서의 신축작동에 따른 틈발생으로 누수되는 유체의 누설을 1차적으로 벨로우즈(150)와 파우더패킹에 의하여 형성되는 공간(b)에 의하여 차단시키는 것이다. 이러한 유체누설은 단열이중관의 조인트부분에 적용된 신축이음구조에서는 빈번하게 일어나는 것이며, 패킹실린더를 통한 파우더패킹으로써 틈을 차단하고, 유체의 누설을 방지하는 것이다.Since the expansion joint device of the heat insulation double pipe of the present invention has a vacuum between the inner side of the outer tube 100 and the outer side of the inner tube 110, the leakage of fluid leaked due to the occurrence of gaps due to the stretching operation in the inner tube 110. It is blocked by the space (b) formed primarily by the bellows 150 and the powder packing. Such fluid leakage occurs frequently in the expansion joint structure applied to the joint portion of the insulated double pipe, and is to prevent the leakage of fluid by blocking the gap by powder packing through the packing cylinder.
본 발명 단열이중관의 신축이음장치는 첨부 도면 도 5에서 도시하는 바와같이 여러가지 외부적 조건 즉 하절기 고열에 의하여 내관이 늘어나거나 하는 변화들에 따라 내관이 신축되면 벨로우즈관(150)이 수착되어 신축이음관(140)을 이동시키게 되는 것이다.When the inner pipe is stretched according to various external conditions, that is, the inner pipe is expanded or changed due to high temperature in summer, as shown in FIG. 5, the bellows pipe 150 is squeezed and stretched. The sound tube 140 is to be moved.
이와같은 신축작용으로 그 늘어나는 길이만큼 신축이음관(140)은 이동하게 되고 여기에 연결된 벨로우즈관(150)이 함께 수축되는 것이며, 장기간 신축작용에 따라 파우더패킹(141)부분에서 유체의 누설이 발생되면, 정기적인 유체누설 확인구(160)의 점검시에 누설유체는 확인되는 것이다.Such expansion and contraction of the expansion joint pipe 140 is moved by the length of the extension and the bellows pipe 150 is connected to it is contracted together, the fluid leakage occurs in the powder packing 141 in accordance with the long-term stretching action When the fluid leakage check port 160 is checked regularly, the leakage fluid is checked.
이후 유체를 제거함과 동시에 외관(100)측의 투입구(102)를 통하여 그 하방의 패킹실린더(142)에 파우더패킹을 주입함으로써 상술한 공간(b)의 일부를 차단하는 패킹부분을 보강하여 밀폐력을 유지하게 되는 것이다.After removing the fluid and at the same time by injecting powder packing into the lower packing cylinder 142 through the inlet 102 of the exterior 100 to reinforce the sealing portion to block the part of the above-mentioned space (b) to improve the sealing force Will be maintained.
특히, 종래에는 외관(100)과 내관(110)사이를 하나의 수직관체로서 패킹실린더를 구성하여 외관측에서 파우더패킹을 투입하도록 되어 있었으나 상기한 바와같은 내관의 신축이동에 따른 진동에 의하여 그 수직상태가 유지되기 어려우나, 본 발명은 외관측에 투입구(102)와 캡(104)를 독립적으로 구성하였으므로 내관(110)상에 설치된 내관의 신축이동에 따른 진동등에 전혀 영향받지 않는 것이다.Particularly, in the related art, a packing cylinder was formed between the exterior 100 and the inner tube 110 as one vertical tube to inject the powder packing from the exterior side, but the vertical direction was caused by the vibration caused by the expansion and contraction of the inner tube. Although it is difficult to maintain the state, the present invention is configured independently of the inlet 102 and the cap 104 on the exterior side is not affected by vibrations or the like due to the expansion and contraction of the inner tube installed on the inner tube 110.
첨부 도면중 도 6은 본 발명 단열이중관의 신축이음장치가 구현된 다른 실시예의 단면도이다. 이 실시예의 신축이음장치는 벨로우즈관(150)이 일측에만 구현된 실시예로서 비교적 배관의 전체길이가 짧은 경우에 적용되는 예로서 그 구체적인 작동구조는 상기한 1실시예의 일측과 동일하므로 생략한다.Figure 6 of the accompanying drawings is a cross-sectional view of another embodiment in which the expansion joint device of the heat insulation double pipe of the present invention is implemented. The expansion joint of this embodiment is an embodiment in which the bellows pipe 150 is implemented only on one side and is applied to a case in which the overall length of the pipe is relatively short, and thus its specific operation structure is the same as that of one side of the above-described embodiment.
첨부 도면중 도 7은 유체누설 확인구의 지표면 시공시 유체누설압에 의해서는 열리고,외부로 부터의 우수 및 오물은 유입이 방지되는 압력조절 벤트밸브(180)의 설치상태를 나타내는 개략 단면도이다.7 is a schematic cross-sectional view showing an installation state of the pressure regulating vent valve 180 which is opened by the fluid leakage pressure during construction of the ground surface of the fluid leakage check port, and rainwater and dirt from the outside are prevented from entering.
이 도면에서 도시하는 바와같이 도로상이나 지표상에 유체누설확인구(160)가 위치하는 경우 이를 알려진 맨홀구조와 같이 하우징(181)과 덮개(182)를 구성한 뒤 그 내측 확인구(160)상단부에 프레임(184)을 설치하고 벤트밸브(186)과 밸브커버(187)를 설치하며,밸브커버(187)위에는 스프링(185)로서 탄압되게 하여 스프링의 압력이상에서는 열리도록 하며, 수동조작을 위하여 수동개폐용 수동레버(183)도 설치된다.As shown in this figure, when the fluid leakage check opening 160 is located on the road or on the ground, the housing 181 and the cover 182 are configured like a known manhole structure, and then the inner check opening 160 is disposed on the upper end thereof. The frame 184 is installed, the vent valve 186 and the valve cover 187 are installed, and the valve cover 187 is pressurized as a spring 185 to be opened above the pressure of the spring, and manually operated for manual operation. Opening and closing manual lever 183 is also installed.
이상 설명한 바와같이 본 발명은 단열재 충진공간에 단열재와 함께 소정압력의 진공을 유지토록하여 단열을 배가한 효과를 갖는다.As described above, the present invention has an effect of doubling the insulation by maintaining a vacuum of a predetermined pressure together with the insulation in the insulation filling space.
본 발명은 종래에 이중관이 단열재 충진공간상에 단열재와 함께 누수감지선을 배선함에 따라 장거리 배관중 다수 신축이음부에서 발생되는 누수위치를 파악할 수 없던 문제점을 개선하여 유체가 누설되는 신축이음부분의 위치확인이 용이하고, 유체누설이 발생된 신축이음관 위치에서 즉각적으로 누설유체를 제거함과 동시에 누설부분의 분해/해체없이 간단하게 파우더패킹이 신속하게 이루어지는 효과를 갖는다. The present invention improves the problem that the double pipe is not able to grasp the leak location generated in a number of expansion joints of the long distance piping by connecting the leak detection line with the insulation on the insulation filling space of the expansion joint portion where the fluid leaks It is easy to check the position, and at the same time the fluid leakage occurs in the expansion joint pipe position immediately removes the leakage fluid and at the same time has the effect that the powder packing can be quickly carried out without disassembly / disassembly of the leakage part.
본 발명은 분기관이 형성되는 신축이음관에서 신축작동에 원활하도록 벨로우즈관을 채택하여 유체가 누설되더라도 단열/진공공간으로 누설되지 않고 유체누설이 확인되는 독립적인 공간을 형성하여 누설유체의 단열재 충진공간으로 누설되지 않도록 하여 누설유체의 확인은 물론 응급조치가 신속해지는 효과를 갖는다.The present invention adopts a bellows pipe in the expansion joint pipe in which the branch pipe is formed to form a separate space in which the fluid leakage is confirmed without leaking into the adiabatic / vacuum space even if the fluid is leaked, filling the insulation of the leakage fluid. This prevents leakage to the space and has the effect of confirming leaking fluid and of making quick emergency measures.
본 발명은 이와같은 개선점으로 인해 장거리 유체이송시 유체누설이 없는 분기관의 설비가 가능하게 되는 효과를 갖는다.The present invention has the effect that it is possible to install the branch pipe without fluid leakage during long-distance fluid transfer.
