By using the heating and heat insulation pipe of the present invention, gas and liquid can be transferred while effectively heating and keeping heat even in a complicated pipe path constructed using a pipe joint.

従来の加熱・保温配管は、導管（ホース、チューブ）の外面にコードヒータを沿わせて当該導管中を流れている気体や液体の温度を昇温又は保温するようにしているが、コードヒータを導管に固定する手法では均熱層、保温層、外装安定層及び保護層（副材料）による包被が必要になる（例えば、特許文献１。）。   In conventional heating and heat insulation piping, a cord heater is placed along the outer surface of a conduit (hose, tube) so that the temperature of the gas or liquid flowing in the conduit is raised or kept warm. In the method of fixing to a conduit, covering with a soaking layer, a heat retaining layer, an exterior stable layer, and a protective layer (submaterial) is required (for example, Patent Document 1).

したがって、従来加熱・保温配管では、(1) 上記副材料のコストが大きく、(2) 外径が大きく、(3) 複雑な配管レイアウトには対応ができない、という問題があった。   Therefore, conventional heating and heat insulation pipes have the following problems: (1) the cost of the secondary material is large, (2) the outer diameter is large, and (3) it cannot cope with a complicated pipe layout.

このため、この種の加熱・保温配管を取り扱う業界では、低コストで、外径が大きくならず、複雑な配管レイアウトに対応できるものが開発されることを待ち望んでいる。

以下にこの発明の加熱・保温管を実施するための最良の形態としての実施例について詳細に説明する。   Embodiments as the best mode for carrying out the heating and heat insulation tubes of the present invention will be described in detail below.

図１はこの発明の実施例の加熱・保温管１を用いた流体移送のシステムＳの概念図、図２はコードヒータ１１に送電するリード３が管継手２から引き出される部分の断面図を示している。
（この加熱・保温管１を有したシステムＳの構成について）
このシステムＳは、図１に示すように、高位置にある液体タンクＴ１に収容されている液体Ｆを、低位置にある液体タンクＴ２に送る途中で所定の温度まで昇温せしめるものであり、前記液体タンクＴ１，Ｔ２相互間を加熱・保温管１で繋いである。これには、必要に応じてタンクＴ１の後ろにポンプを介在させることができる。 FIG. 1 is a conceptual diagram of a fluid transfer system S using a heating / insulating tube 1 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of a portion where a lead 3 for transmitting power to a cord heater 11 is pulled out from a pipe joint 2. ing.
(Regarding the configuration of the system S having the heating / heat insulation tube 1)
As shown in FIG. 1, the system S raises the temperature of the liquid F stored in the liquid tank T1 at the high position to a predetermined temperature while being sent to the liquid tank T2 at the low position. The liquid tanks T1 and T2 are connected to each other by a heating / insulating tube 1. For this purpose, a pump can be interposed behind the tank T1 as necessary.

加熱・保温管１は、図１に示すように、導管１０及びこれの両端に接続されたＴ字型の管継手２，２中にコードヒータ１１を挿通して成るものとしており、前記した一方の管継手２は液体タンクＴ１に、他方の管継手２は液体タンクＴ２に、それぞれ取り付けられている。そして、各管継手２の上に延びる管部２０内において、上記コードヒータ１１と前記コードヒータ１１に送電するリード線３を電気的接続状態にしている。   As shown in FIG. 1, the heating and heat insulation pipe 1 is formed by inserting a cord heater 11 into a conduit 10 and T-shaped pipe joints 2 and 2 connected to both ends thereof. The pipe joint 2 is attached to the liquid tank T1, and the other pipe joint 2 is attached to the liquid tank T2. And in the pipe part 20 extended on each pipe joint 2, the lead wire 3 which transmits electric power to the said code heater 11 and the said code heater 11 is made into the electrical connection state.

ここで、コードヒータ１１に送電するリード線３が管継手２から引き出される部分は、図２に示すように、管部２０に嵌入されるキャップ４と、前記キャップ４の凹み部４０内に充填される封止部材５とから構成されており、前記凹み部４０内においてコードヒータ１１の端部とリード線３とが接続（接続部を符号ｔで示す）されている。   Here, as shown in FIG. 2, the portion where the lead wire 3 that transmits power to the cord heater 11 is pulled out from the pipe joint 2 is filled in the cap 4 fitted into the pipe portion 20 and the recess 40 of the cap 4. The end portion of the cord heater 11 and the lead wire 3 are connected in the recessed portion 40 (the connection portion is indicated by a symbol t).

導管１０は、気体や液体を移送するものであり、樹脂（例えばフッ素樹脂）または金属により構成されている。   The conduit 10 is for transferring gas or liquid and is made of resin (for example, fluororesin) or metal.

コードヒータ１１は、ニクロム線にシリコンを被覆したものを使用している。   The code heater 11 uses a nichrome wire coated with silicon.

管継手２は、上記した導管１０と同じ材質のもので構成されている。   The pipe joint 2 is made of the same material as that of the conduit 10 described above.

キャップ４は、ナイロンやフッ素樹脂等の樹脂材料で構成されている。   The cap 4 is made of a resin material such as nylon or fluororesin.

封止部材５は、シリコン製シーラントにより構成されている。
（この加熱・保温管１を有したシステムＳの優れた機能について）
(1) この加熱・保温管１では液体が流れる導管１０及び管継手２，２内にコードヒータ１１を挿通させる構成を採っているので、コードヒータ１１の発熱を効率良く液体に伝熱できる。 The sealing member 5 is made of a silicon sealant.
(About the excellent function of the system S having this heating and heat insulation tube 1)
(1) Since the heating / insulating tube 1 has a configuration in which the cord heater 11 is inserted into the conduit 10 and the pipe joints 2 and 2 through which the liquid flows, the heat generated by the cord heater 11 can be efficiently transferred to the liquid.

なお、この加熱・保温管１では、凍結した液体を加熱する場合、コードヒータ１１の周りから溶解して液体化し、安定した送液が可能になる。
(2) この加熱・保温管１では、導管１０上に均熱層、保温層、外装安定層及び保護層（副材料）を包被する必要がないから、低コストである。
(3) この加熱・保温管１では、導管１０上に均熱層、保温層、外装安定層及び保護層（副材料）を包被する必要がないから、外径が大きくならず、複雑な配管レイアウトにも対応ができる。
(4) この加熱・保温管１では、管継手２内においても液体の昇温が可能である。
(5) この加熱・保温管１を有したシステムＳでは、外部の電源Ｄ（温度調整器）の電圧調整により、所望に温度管理できる。 In addition, in this heating / heat-retaining tube 1, when the frozen liquid is heated, it is melted from around the cord heater 11 to be liquefied, and stable liquid feeding becomes possible.
(2) The heating / insulating tube 1 is low in cost because it is not necessary to cover the conduit 10 with a soaking layer, a heat insulating layer, an exterior stable layer and a protective layer (submaterial).
(3) In this heating / insulating tube 1, it is not necessary to enclose a soaking layer, a heat insulating layer, an exterior stable layer and a protective layer (submaterial) on the conduit 10, so the outer diameter does not increase and is complicated. It can also be used for piping layout.
(4) In the heating and heat insulation tube 1, the temperature of the liquid can be raised even in the pipe joint 2.
(5) In the system S having the heating / insulating tube 1, the temperature can be controlled as desired by adjusting the voltage of the external power source D (temperature regulator).

上記した(1) 〜(5) により、このシステムＳでは、タンクＴ１内の液体を導管１０による移送途中で効率良く所望の温度にして、タンクＴ２内に投入することができる。
(6) また、既存の導管１０にコードヒータ１１を入れるだけなので、生産上の効率が上がる。
（他の実施の形態について）
上記したコードヒータ１１に送電するリード線３が管継手２から引き出される部分の構成を図３に示すように変更できる。この構成は、基本的には、ナイロンやフッ素樹脂等の樹脂材料より成る二つのキャップ体６０，６１相互を螺合（雌ネジ６２、雄ネジ６３による）させて空間部Ｋを構成し、前記空間Ｋ内にリード線３とコードヒータ１１との接続部ｔを収容させると共に二つのシリコン製のＯリングＲにより空間部Ｋ内に流体が侵入しないようにしてある。ここで、この構造を採用した場合、前記キャップ体６１に形成した雄ネジ６３を、管部２０に形成された雌ネジに螺入することにより管継手２にネジ結合される。なお、管部２０への取り付けに際して、管部２０の内周壁とキャップ体６１の外周壁相互間の気密性を確保すべく、管部２０の内壁にＯリングＲ’を設けておくことが必要である。 According to the above (1) to (5), in this system S, the liquid in the tank T1 can be efficiently put into the tank T2 at a desired temperature while being transferred through the conduit 10.
(6) In addition, since the cord heater 11 is simply inserted into the existing conduit 10, the production efficiency increases.
(About other embodiments)
The configuration of the portion where the lead wire 3 that transmits power to the cord heater 11 is pulled out from the pipe joint 2 can be changed as shown in FIG. In this configuration, basically, the cap portion 60, 61 made of a resin material such as nylon or fluororesin is screwed together (by the female screw 62 and the male screw 63) to form the space portion K. The connection portion t between the lead wire 3 and the cord heater 11 is accommodated in the space K, and fluid is prevented from entering the space portion K by two silicon O-rings R. Here, when this structure is adopted, the male screw 63 formed on the cap body 61 is screwed into the pipe joint 2 by screwing into the female screw formed on the pipe portion 20. In addition, when attaching to the pipe part 20, it is necessary to provide an O-ring R ′ on the inner wall of the pipe part 20 in order to ensure airtightness between the inner peripheral wall of the pipe part 20 and the outer peripheral wall of the cap body 61. It is.

上記実施例１では、液体を導管１０内で加熱しながら移送するようにしたが、これに限定されることなく、所定の温度の液体を導管１０内で保温しながら移送するようにしてもよい。   In the first embodiment, the liquid is transferred while being heated in the conduit 10. However, the present invention is not limited to this, and a liquid having a predetermined temperature may be transferred while being kept warm in the conduit 10. .

上記実施例１では、管継手２を使用しているが、管継手２は必須ではない。   In the said Example 1, although the pipe joint 2 is used, the pipe joint 2 is not essential.

上記実施例１では、管継手２としてＴ字型のものを使用したが、これに限定されることなく、Ｆ字型、十字型でもよい。要するに、三回路以上を有するものであれば全て採用できる。   In the said Example 1, although the T-shaped thing was used as the pipe joint 2, it is not limited to this, F shape and a cross shape may be sufficient. In short, any one having three or more circuits can be employed.

上記実施例１では、移送する対象を液体としているが、気体とすることもできる。   In the first embodiment, the object to be transferred is a liquid, but may be a gas.
