【発明の詳細な説明】
本発明は自動車工業、化学工業、その他金属表面処理工
業、メッキ工業等に適用される薬液用熱交換装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chemical heat exchange device applied to the automobile industry, chemical industry, other metal surface treatment industries, plating industry, etc.
この種の熱交換装置は冷却すべき対象および加熱すべき
対象が硫酸等の薬液であるために、薬液と冷媒および熱
媒との熱交換には耐薬液性にすぐれたフッ素樹脂、例え
ばテフロン（商標）が用いられる。In this type of heat exchange device, the object to be cooled and heated is a chemical liquid such as sulfuric acid, so for heat exchange between the chemical liquid and the refrigerant or heating medium, a fluororesin with excellent chemical resistance, such as Teflon ( Trademark) is used.
このようなテフロン製熱交換装置の一つとして、第８図
に示すように極細径のテフロン製チューブＡを用い、此
等を多数本束状に一体的に結合させてバンド様体Ｂで結
束して、集合チューブの横断面がハチの巣状を呈する形
状を与え、各チューブＡ内に熱媒、例えばスチームを流
通させるようにしたものがある。As one such Teflon heat exchange device, as shown in Fig. 8, Teflon tubes A with an extremely small diameter are used, and a large number of these tubes are integrally combined into a bundle and bound with a band-like body B. There is one in which the cross section of the collecting tubes is given a honeycomb-like shape, and a heating medium, such as steam, is allowed to flow through each tube A.
しかしながら、このような構造では、各チューブを薄く
形成することから内圧の上昇等で破損し易く、しかも各
チューブが分離不能に一体結合しているため破損チュー
ブの取替が不可能である。However, in such a structure, since each tube is formed thin, it is easily damaged due to an increase in internal pressure, and furthermore, since each tube is integrally connected inseparably, it is impossible to replace a damaged tube.
これに対して、上下に平行に配した支持パイプの中間部
相互を連結固定する連結板と連結板の両側位置に線対称
的にＸ字状に設置されて上記両支持パイプ間を連結する
支持板とに、比較的小径の熱交換用パイプを複数本並列

漸次縮径されていく方向にうす巻き状に挿通保持せしめ
、各パイプの入力側端および出力側端をそれぞれ入力側
および出力側のコネクタに連通連結した構造のものがあ
る。On the other hand, there is a connecting plate that connects and fixes the intermediate parts of the support pipes arranged in parallel vertically, and supports that are installed in an X-shape symmetrically on both sides of the connecting plate and connect the support pipes. A plurality of relatively small-diameter heat exchange pipes are inserted and held in parallel in the plate in a thinly wound manner in a direction in which the diameter is gradually reduced from the outside with respect to the connecting plate and the support plate, and each pipe is There is a structure in which the input side end and the output side end are connected to connectors on the input side and output side, respectively.
この装置では、各パイプの実長を長くしても装置がコン
パクトとなり、各パイプを微細径とする必要がないため
に破損しない強靭なものとでき、仮に破損してもその発
見と取替そが容易である等の種々の利点がある。With this device, even if the actual length of each pipe is increased, the device is compact, and since each pipe does not need to have a small diameter, it can be made strong and will not break, and even if it does break, it can be detected and replaced. It has various advantages such as ease of use.
ところがこのような装置においては複数の熱交換用パイ
プを入力側および出力側コネクタに個別に接続するので
、この接続部においてスチーム等の熱交換媒体の漏れを
確実に防止する必要があるが、上記媒体にて熱膨張した
接続部分の部材間で熱膨張量の差を生じ、接続部分に通
常介在させるリングパッキンに対する圧縮力が変化して
シール効果が損なわれ易いという問題がある。However, in such devices, multiple heat exchange pipes are connected individually to the input and output connectors, so it is necessary to reliably prevent leakage of heat exchange media such as steam at these connections. There is a problem in that a difference in the amount of thermal expansion occurs between the members of the connection part that have been thermally expanded in the medium, and the compressive force applied to the ring packing that is normally interposed in the connection part changes, which tends to impair the sealing effect.
また、パイプに薬液を供給する場合ではパイプの分子間
を通して薬液のガス通過が生じ、接続部材とパイプとの
空隙部に透過ガスが滞溜して接続部材が損傷することが
ある。Furthermore, when a chemical solution is supplied to a pipe, the gas of the chemical solution may pass through the molecules of the pipe, and the permeated gas may accumulate in the gap between the connecting member and the pipe, causing damage to the connecting member.

肉厚になっている。Reference numeral 31 denotes a ring packing made of Teflon, which has a triangular cross section and is thicker on the inner circumferential side than on the outer circumferential side.
接続にあたっては、パイプ８をパイプ挿入孔２９側から
挿入して、パイプ先端をテーパ面３０に沿わせる。For connection, the pipe 8 is inserted from the pipe insertion hole 29 side, and the tip of the pipe is aligned with the tapered surface 30.

雌ねじ部２８とによって捻じこみ固定する。From this state, the ring packing 31 is inserted from the side of the branch insertion hole 27, and one inclined side surface 3 of the ring packing 31 is inserted.
The plug 9 is screwed into the branch port 24 by the male threaded part 26 and the female threaded part 28 so that the pipe tip is held between the pipe 1a and the tapered surface 30.

３ｌｂに当接される。On the other hand, a tapered surface 32 corresponding to the stepped tapered surface 30 on the inner periphery of the plug is also formed at the inner corner of the mouth tube 25 forming the branch port 24, and as the plug 9 is screwed in, the tapered surface 32 corresponds to the stepped tapered surface 30 on the inner circumference of the plug. The tapered surface 32 is brought into contact with the other inclined side surface 3lb of the ring packing 31.

A compressive force is applied from the direction 31b, and the tip of the pipe is strongly sealed between the plug side taper surface 30 and the ring packing 31, and the taper surface 3 of the branch pipe 25
2 and the ring packing 31 are also sealed.
従ってコネクタ１２側からパイプ８にスチームが流れる

を有効裡に現出させる効果がある。Note that the circulating steam causes thermal expansion in the pipe 8, mouth pipe 25, and plug 9, and the difference in the amount of thermal expansion may cause a change in the compressive force on the ring packing 31. However, the ring packing 31 of the present invention It has a triangular cross section,
Since the wall thickness on the inner peripheral surface side is formed to be thicker than that on the outer peripheral surface side, both inclined side surfaces 31 a . Even if a compressive force is applied to 31b from both sides, the inner circumferential surface side stores sufficient elastic force due to its thick wall structure, and the ring packing 31 deforms in response to the compressive force, and the ring packing 31 deforms accordingly. This has the effect of effectively bringing out the sealing effect in.
３３はガス抜き孔である。33 is a gas vent hole.
即ち、コネクタ１２側からパイプ８に供給されるものが
薬液である場合には、パイプ８の分子間を通して薬液の
ガス透過が生じ、これがパイプ８外に洩れる。That is, when a chemical liquid is supplied from the connector 12 side to the pipe 8, gas permeation of the chemical liquid occurs through the molecules of the pipe 8, and this leaks out of the pipe 8.
そして該透過ガスがパイプ８とプラグ９との空隙部に滞

８との空隙部に滞溜しようとするガスを、プラグ９外に
確実に放散させる役目を成す。This gas vent hole 32 serves to reliably diffuse the gas that tends to accumulate in the gap between the plug 9 and the pipe 8 due to the gas permeation to the outside of the plug 9.

のである。As described above, the chemical liquid heat exchange device according to the present invention has the first
In the structure shown in Figures to 6, when connecting the input side end and output side end of each heat exchange pipe to the input side and output side connectors, the number of heat exchange pipes to be connected to both connectors corresponds to the number of heat exchange pipes to be connected to both connectors. A branch port is provided and a tapered surface is formed at the opening end of each branch port, while a heat exchange pipe insertion port having a smaller diameter than the branch port insertion port is provided, and a substantially figure-eight shape is provided at the tip of the pipe opening with respect to the tapered surface. A plug is used that has a stepped tapered surface corresponding to the shape and a through hole extending from the outer circumferential surface to the heat exchange pipe insertion port.The heat exchange pipe is inserted into this plug, and the end thereof is inserted as described above. A ring packing whose outer circumferential surface is inclined on both sides and has a substantially triangular cross section is inserted along the tapered surface of the stepped portion, and this plug is then screwed into the branch port pipe of the connector. That's what happens.

う優れた効果が奏される。Therefore, according to the present invention, even if there is a difference in the amount of thermal expansion between each member at each connection between the input side and output side connectors and the heat exchange pipe, the ring packing having a substantially triangular cross section is able to resist fluctuations in compressive force. As a result, the sealing effect is sufficient, and since the plug is provided with a gas vent hole, damage to the plug due to permeated gas can be avoided even when a chemical solution is supplied to the pipe, which is an excellent effect.
