FIG. 3A is a first embodiment of a heating wire, and FIG. 3B is a second embodiment of a heating wire.
도 1 및 도 2를 참조하면, 본 발명의 일 실시 예에 따른 보온히팅커버(9)는, 내피 및 외피(32,31), 발열유닛(19) 및 단열재(10)를 포함한다.1 and 2 , the heat insulating heating cover 9 according to an embodiment of the present invention, the inner and outer shell 32, 31, the heat generating unit 19 and the heat insulating material (10).
내피 및 외피(32,31)는 열선 발열유닛(19) 및 단열재(10)를 모두 감싸는 보온히팅커버(9)의 표면을 구성하는 것으로서, 내피 및 외피(32,31) 모두 상기 내피 및 외피(32,31)는, 폴리테트라 플루오로에틸렌(PTFE) (Polytetrafluoroethylene) 재질로 구성되어 있다. 즉, 폴리테트라 플루오로에틸렌(PTFE) (Polytetrafluoroethylene)을 연신가공하여 생성한 PTFE 섬유이며, PTFE 섬유를 가열하여 PTFE 섬유 시트를 만들어 내피 및 외피로 사용한다. Endothelial and the outer shell (32, 31) constitutes the surface of the heating heating cover (9) surrounding both the heating wire heating unit 19 and the heat insulator (10), the inner and outer shell (32, 31) both the inner and outer shell ( 32 and 31 are made of polytetrafluoroethylene (PTFE). That is, it is a PTFE fiber produced by stretching polytetrafluoroethylene (PTFE) (Polytetrafluoroethylene), the PTFE fiber is heated to make a PTFE fiber sheet to be used as the inner and outer skin.
플루오로에틸렌(PTFE)은 감촉이 좋고, 내열성과 내 약품성이 탁월하다. 인체에 전혀 무해하고 화학성, 열적 안정성이 좋아 크린룸 내에서도 안심하고 사용할 수 있는 소재이다. 또한, 매우 넓은 온도 범위에서(-200℃ ~ 260℃) 사용할 수 있고, 필름 등이 적층되어 있지 않아 직물 특유의 바이어스 방향으로 신축성이 좋은 장점이 있다. 복잡한 형상의 보온재나 히터제작이 용이하고, 인장강도는 같은 온도에서 유리섬유에 비하여 20배 정도 높은 것으로 확인되었다. 또한, 플루오로에틸렌(PTFE)은 칼이나 가위등에 절단되지 않아, 제단시에는 특수 가위를 사용하여 재단한다.Fluoroethylene (PTFE) has a good feel and is excellent in heat resistance and chemical resistance. It is harmless to human body, and has good chemical and thermal stability, so it can be used safely in clean room. In addition, it can be used in a very wide temperature range (-200 ℃ ~ 260 ℃), there is an advantage that the elasticity is good in the bias direction peculiar to the fabric because the film or the like is not laminated. It is easy to manufacture complicated shape insulation and heater, and the tensile strength was found to be about 20 times higher than glass fiber at the same temperature. In addition, fluoroethylene (PTFE) is not cut by a knife or scissors, and is cut using special scissors at the time of cutting.
발열유닛(19)는, 열선 클로스(cloth)(53)에 시침실(18)에 의해 고정된 열선(20)으로 구성된다. 열선 클로스(cloth)(53)는 글라스 섬유사로 싼 직물이며, 도 1 및 2를 참조하면, 일 측은 PTFE 재질의 내피(32)와 접촉되고 타측은 열선(20)과 접촉되도록 설치된다. 열선 클로스(53)는 열선(20)에서 발산되는 열을 받아 내피(32)로 전달하는 역할을 하며, 보온에 효과적이다.The heat generating unit 19 is constituted by a hot wire 20 fixed to a hot wire cloth 53 by an hour hand chamber 18. Hot cloth (cloth) (53) is a cloth wrapped in glass fiber yarn, and referring to Figures 1 and 2, one side is installed to contact the endothelial 32 of the PTFE material and the other side is in contact with the heating wire (20). The hot wire cloth 53 serves to receive heat emitted from the hot wire 20 and deliver it to the endothelium 32, and is effective for keeping warm.
열선(heating wire unit)(20)은, 도 2 및 도 3a, 도 3b를 참조하면, 단열재(10)와 글라스 클로스(53) 사이에 설치된다. 열선(20)의 구조는 두 가지 실시 예로 구성할 수 있는데, 도 3a의 열선(20a)과 같이 히팅 와이어(61)와 이를 피복하는 유리피복층(62)으로 구성될 수 있으며, 도 3b에 도시된 열선(20b)과 같이 유리섬유(63)와, 이를 나선형태로 감싸는 히팅와이어(61), 히팅와이어(61)를 피복하는 유리피복층(62)으로 구성될 수 있다. 상술한 히팅 와이어(61)는 니크롬선이며 유리섬유가 코팅되어 있다(glass coated Ni-Cr heating wire). 이러한 구조의 열선(20a,20b)은 열 전달성이 좋고 유리섬유피복층(62)을 통해 열이 골고루 분산되어 전달된다.The heating wire unit 20 is provided between the heat insulating material 10 and the glass cloth 53 with reference to FIGS. 2, 3A, and 3B. The structure of the heating wire 20 may be configured in two embodiments, such as the heating wire 61 and the glass coating layer 62 covering the heating wire 61, as shown in the heating wire 20a of FIG. 3A. Like the heating wire 20b, the glass fiber 63, the heating wire 61 which surrounds it in a spiral shape, and the glass coating layer 62 covering the heating wire 61 may be configured. The heating wire 61 is a nichrome wire and is coated with glass fiber (glass coated Ni-Cr heating wire). The heat wires 20a and 20b of this structure have good heat transfer properties and heat is evenly distributed through the glass fiber coating layer 62.
단열재(10)는, 도 2를 참조하면, 열선(20)과 외피(31) 사이에 설치된다. 단열재(10)는 실리카(Silica, SiO2) 섬유로 구성되거나 아라미드 펠트(aramid felt)로 구성될 수 있다. 둘 다 단열성이 좋고 열에 강한 재질로서, 열선에서 발산되는 열이 외부로 전달되는 것을 차단한다.Referring to FIG. 2, the heat insulating material 10 is provided between the heating wire 20 and the outer shell 31. The heat insulator 10 may be composed of silica (Silica, SiO 2) fibers or may be composed of aramid felt. Both are heat insulating and heat resistant materials, which block heat from being emitted from the hot wire to the outside.
이하에서는 도 4 내지 도 8을 참조하여, 본 발명의 일 실시 예에 따른 배관자재용 히팅보온 커버(9)를 제작하는 방법에 대하여 설명한다. Hereinafter, with reference to FIGS. 4 to 8, a method of manufacturing the heating insulation cover 9 for a piping material according to an embodiment of the present invention will be described.
먼저, 히팅보온커버(9)가 설치될 배관자재의 직경 및 길이 등 크기와 모양을 실측한다(S1). 배관설계도면은 실제 설치된 배관의 사이즈와 다른 경우가 많다. 따라서, 실재 배관자재의 크기와 모양을 정확히 측정한 다음 이를 도면화한다. 도면은 몰드 제작에 사용된다.First, the size and shape, such as the diameter and length of the piping material to be installed the heating insulation cover 9 is measured (S1). Piping design drawings are often different from the actual pipe size. Therefore, the size and shape of the actual piping material accurately measured and then drawing it. The drawing is used to make a mold.
그런 다음, 실측을 바탕으로 그려진 도면을 바탕으로 몰드(90)를 제작한다(S2). 몰드(90)는 실재 배관의 크기 및 모양과 동일하게 제작되고, 제작의 편의와 시침 바늘(91)이 잘 꽂아질 수 있는 재질을 사용하는 것이 바람직하다. 도 5는 본 실시 예의 몰드(90)를 그린 도면으로서, 스치로폼으로 제작된 것이다.Then, a mold 90 is manufactured based on the drawing drawn on the basis of actual measurement (S2). Mold 90 is manufactured in the same size and shape of the actual pipe, it is preferable to use a material that can be easily inserted and the convenience of the needle and the needle 91. FIG. 5 is a drawing of a mold 90 according to the present embodiment, and is made of styrofoam.
그런 다음, 도 6과 같이 몰드(90)의 사이즈에 맞추어 단열재(10)를 재단하고 시침바늘(91)로 고정시킨다(S3). 즉 단열재(10)를 몰드 사이즈에 맞게 자른 후 자른 끝단을 시침핀(91)으로 몰드(90)에 임시 고정시킨다. Then, as shown in FIG. 6, the heat insulating material 10 is cut to fit the size of the mold 90 and fixed with an hour hand needle 91 (S3). That is, after cutting the heat insulating material 10 to the mold size, the cut end is temporarily fixed to the mold 90 with the test pin 91.
그런 다음, 발열유닛(19)을 재단하고 시침한다(S4). 발명유닛(19)을 제작하기 위해 먼저 열선클로스(53)를 몰드 사이즈에 맞게 재단한다. 즉 열선클로스(53, 열선고정 직물)를 단열재(10)가 임시 고정되어 있는(도 6 참조) 몰드(90)를 감싸서 알맞은 크기로 자른다. 그런 다음 열선클로스(53)의 크기에 맞게 열선(20)을 자르고, 열선(20)을 유리섬유재질의 시침실(18)을 이용하여 도 7과 같이 지그재그 형태로 재봉하여 열선을 열선클로스(53)에 단단히 고정시킨다. 열선(20)이 지그재그 형태로 미싱된 발열유닛(19)을 다시 몰드(90)에 시침핀(91)으로 임시고정 시킨다. 열선(20)은 열선클로스(53)에 단단히 고정함으로써, 히팅보온커버는 설치 및 분리를 반복하므로 오므렸다 펴졌다하는 횟수가 많고 지속적으로 열을 발산시키는 열선의 특성상, 열선이 열선클로스(53)로부터 이탈되어 열선과 열선이 서로 접촉되어 단선되거 열이 균일하게 전달되지 않는 현상을 방지할 수 있다. Then, the heating unit 19 is cut and tacked (S4). In order to manufacture the invention unit 19, first, the heat ray cloth 53 is cut to fit the mold size. That is, the heat ray cloth 53 (heat wire fixing fabric) is cut to an appropriate size by wrapping the mold 90 to which the heat insulating material 10 is temporarily fixed (see FIG. 6). Then, the heating wire 20 is cut to fit the size of the heating wire 53, and the heating wire 20 is sewn in a zigzag shape as shown in FIG. Firmly). Temporary fixation of the heating unit 19 in which the heating wire 20 is missed in a zigzag form is performed by the hour hand pin 91 on the mold 90 again. Since the heating wire 20 is firmly fixed to the heating wire cloth 53, the heating insulation cover is repeatedly installed and detached, so that the heating wire 20 is frequently retracted and continually dissipates heat. It is possible to prevent the phenomenon that the hot wire and the hot wire is in contact with each other and disconnected or the heat is not evenly transmitted.
그런 다음, 내피(32)를 재단하고 시침한다(S5). 단열재(10) 및 발열유닛(19)이 임시 고정된 몰드(90)의 사이즈에 맞게 내피(32)를 재단하고, 단열재(10)의 두께 및 형태를 유지하면서 내피(32)를 시침한다. 시침실은 유리섬유재의 실을 이용하고, 내피(32)가 단열재(10) 및 발열유닛(19)의 일면 및 측면을 감싸도록 시침실을 이용하여 봉제한다.Then, the endothelium 32 is cut and tacked (S5). The inner shell 32 is cut to fit the size of the mold 90 to which the heat insulating material 10 and the heat generating unit 19 are temporarily fixed, and the endothelial 32 is tacked while maintaining the thickness and shape of the heat insulating material 10. The hour hand chamber is made of a glass fiber material, and the inner shell 32 is sewn using the hour hand chamber so as to surround one side and side surfaces of the heat insulating material 10 and the heat generating unit 19.
그런 다음, 어닐린단계를(annealing) 거친다(S6). 열선(20)을 고온으로 상승시킨 후 온도를 하강시켜 열선유닛(19) 및 단열재(10)에 있을 수도 있는 불순물을 제거시킨다. Then, the process is annealed (S6). After raising the hot wire 20 to a high temperature, the temperature is lowered to remove impurities that may be present in the hot wire unit 19 and the heat insulating material 10.
그런 다음, 배관자재의 온도를 측정하기 위해 내피(32) 외측으로 돌출되도록 온도센서(미도시)를 연결하고, 열선(20)에 전원을 공급하는 리드선(95)을 연결한다(S7). Then, a temperature sensor (not shown) is connected to protrude outside the endothelium 32 to measure the temperature of the piping material, and a lead wire 95 for supplying power to the heating wire 20 is connected (S7).
그런 다음, 몰드(90)를 감싸고 있는 단열재(10), 발열유닛(19) 및 내피(32)를 모두 커버링할 수 있도록 외피(31)를 재단하고 외피를 감침한다(S8). 즉, 외피(31)가 시침된 단열재(10), 내피(32) 및 발열유닛(19)을 덮을 수 있도록 외피의 크기를 재어 재단하고, 재단된 외피(31)를 시침실을 이용하여 단열재(10)의 일면과 측면 및 발열유닛(19)의 측면을 감싸도록 봉제시켜 고정한다.Then, the outer shell 31 surrounding the mold 90, the heating unit 19 and cut the outer shell 31 so as to cover all the inner shell 32 and hide the outer shell (S8). That is, the outer shell 31 is cut and sized so as to cover the heat insulating material 10, the inner skin 32, and the heat generating unit 19 that are tacked, and the cut skin 31 is cut by using a heat sink ( One side and side of the 10 and the side of the heat generating unit 19 is sewn to secure the wrap.
그런 다음, 외피(31)에 탈부착부재(92,93)를 고정시킨다(S9). 탈부착부재는 도 8을 참조하면, 암수 벨크로(92,93)로 구성될 수 있다. 밸크로를 고정시킴으로써 히팅보온커버(9)의 착탈을 쉽게 할 수 있다.Then, the removable member (92, 93) is fixed to the outer shell (31) (S9). 8, the detachable member may be composed of male and female velcros 92 and 93. The fixing of the velcro makes it easy to attach and detach the heating insulation cover (9).
그런 다음, 리드선에 커넥터(96) 등을 연결시킨다(S10). Then, the connector 96 and the like are connected to the lead wire (S10).
