Description

本発明は、フランジどうしを結合することにより、配管どうしを接続するようにした配管フランジに関する。   The present invention relates to a pipe flange that connects pipes by joining the flanges together.

車両用空調装置は、冷媒を循環させて室内空気と蒸発器とで熱交換を行なうものであり、膨張弁を通って断熱膨張した冷媒は、気体と液体との二相の状態となって蒸発器に入り、この蒸発器において外部からの熱を吸収して気化（蒸発）し、等温膨張を続けて車室内の空気を冷却する。そして、過熱蒸気となって、圧縮機に吸入される。   A vehicle air conditioner circulates refrigerant and exchanges heat between indoor air and an evaporator. The refrigerant adiabatically expanded through the expansion valve evaporates in a two-phase state of gas and liquid. In this evaporator, heat from the outside is absorbed and evaporated (evaporated) in this evaporator, and the air in the passenger compartment is cooled by continuing isothermal expansion. Then, it becomes superheated steam and is sucked into the compressor.

このような車両用空調装置における、蒸発器の部分に、配管フランジが設けられている。従来の配管フランジは、特許文献１に記載のように構成されている。冷媒を供給・流出させるための供給用配管の端部と流出用配管の端部とが連結された配管ブロックが、膨張弁を介して蒸発器に接続されており、ボルトを配管ブロックの挿通孔および膨張弁の挿通孔に挿通させた後に、蒸発器に形成された雌ネジ部にねじ込んでいる。   In such a vehicle air conditioner, a pipe flange is provided in the evaporator portion. The conventional piping flange is configured as described in Patent Document 1. A pipe block in which the end of the supply pipe for supplying / flowing out the refrigerant and the end of the outflow pipe are connected to the evaporator via an expansion valve, and the bolt is inserted into the insertion hole of the pipe block. And after making it pass in the insertion hole of an expansion valve, it is screwed in the internal thread part formed in the evaporator.

このような構成と類似する配管フランジの構造を図５に示す。図のように、供給用配管１の端部と流出用配管２の端部とが連結されたフランジ３が、フランジ３の取付孔３ａに挿通した２本のボルト４を介して、蒸発器５と一体のフランジ６の雌ネジ部６ａにねじ込まれている。
特開平７−３２９５４９号公報（図２） FIG. 5 shows a structure of a piping flange similar to such a configuration. As shown in the drawing, the flange 3 in which the end of the supply pipe 1 and the end of the outflow pipe 2 are connected is connected to the evaporator 5 via two bolts 4 inserted into the mounting holes 3 a of the flange 3. And is screwed into the female thread portion 6a of the flange 6 integral with the flange 6.
Japanese Patent Laid-Open No. 7-329549 (FIG. 2)

ところが、フランジ３の表面の面積が小さく、この小さいフランジ３に供給用配管１と流出用配管２との２本の配管が接続されており、図６に示すようにボルト４を下方の取付孔３ａに挿通しようとすると、図５（ｂ）からわかるように、供給用配管１と流出用配管２との狭い空間がボルト４の軸方向に長いために供給用配管１と流出用配管２との間に手が入らず、下方の取付孔３ａにボルト４を円滑に挿通できないという問題がある。   However, the surface area of the flange 3 is small, and two pipes, a supply pipe 1 and an outflow pipe 2, are connected to the small flange 3, and the bolt 4 is attached to the lower mounting hole as shown in FIG. When trying to pass through 3a, as can be seen from FIG. 5 (b), the narrow space between the supply pipe 1 and the outflow pipe 2 is long in the axial direction of the bolt 4, so the supply pipe 1 and the outflow pipe 2 There is a problem that a hand cannot be inserted between the bolts 4 and the bolts 4 cannot be smoothly inserted into the lower mounting holes 3a.

そこで本発明は、上記の課題を解決した配管フランジを提供することを目的とする。 Then, an object of this invention is to provide the piping flange which solved said subject.

請求項１に係る発明は、複数の流路どうしを結合するために、一方の流路を複数形成した第１フランジと、他方の流路を形成した複数の配管を接続した第２フランジとを設け、該第２フランジを貫通するボルトを前記第１フランジの雌ネジ部にねじ込むことによって、前記第１フランジと前記第２フランジとを結合した配管フランジにおいて、前記第２フランジの外周面に、前記第２フランジの厚さ方向に沿って溝を形成し、前記ボルトを前記第２フランジの外周面から前記溝に嵌め込んで前記雌ネジ部にねじ込むようにしたことを特徴とする。   The invention according to claim 1 includes a first flange in which a plurality of channels are formed and a second flange in which a plurality of pipes in which the other channel is formed are connected in order to connect the plurality of channels. In a piping flange that connects the first flange and the second flange by screwing a bolt that penetrates the second flange into the female thread portion of the first flange, on the outer peripheral surface of the second flange, A groove is formed along the thickness direction of the second flange, and the bolt is fitted into the groove from the outer peripheral surface of the second flange and screwed into the female screw portion.

請求項２に係る発明は、請求項１に記載の配管フランジにおいて、前記第１フランジの突き合せ面に、前記の一方の流路が開口する凹部または凸部のいずれか一方を形成しつつ、前記第２フランジの突き合せ面には、前記他方の流路が開口する他方を形成し、前記凸部を前記凹部に嵌合し、前記凸部の外周面と前記凹部の内周面との間にシール材を介在させたことを特徴とする。   The invention according to claim 2 is the piping flange according to claim 1, wherein either one of the concave portion or the convex portion in which the one flow path opens is formed on the butt surface of the first flange. On the butting surface of the second flange, the other opening of the other channel is formed, the convex portion is fitted into the concave portion, and the outer peripheral surface of the convex portion and the inner peripheral surface of the concave portion It is characterized in that a sealing material is interposed therebetween.

請求項１記載の発明によれば、第１フランジと第２フランジとを結合する際に、ボルトを第２フランジの外周面から溝に嵌め込んだ後に、第１フランジの雌ネジ部にねじ込む。ボルトを軸方向に押し込んで第２フランジに挿通させる作業が不要なので、手が配管どうしの間へ入らなくても、ボルトの装着を容易に行なうことができる。   According to the first aspect of the present invention, when the first flange and the second flange are coupled, the bolt is fitted into the groove from the outer peripheral surface of the second flange and then screwed into the female thread portion of the first flange. Since it is not necessary to push the bolt in the axial direction and insert it through the second flange, the bolt can be easily attached even if the hand does not enter between the pipes.

また、請求項２記載の発明によれば、シール材を介して凹部に凸部を嵌め込んで第１フランジと第２フランジとをボルト結合するので、ボルトを強く締めることなく流路どうしを気密に連通通させることができる。   According to the second aspect of the present invention, since the first flange and the second flange are bolted by fitting the convex portion into the concave portion via the sealing material, the flow paths are hermetically sealed without tightening the bolt strongly. Can be communicated with.

以下、本発明の実施の形態を図面に基づいて説明する。なお、ここで示す実施の形態は、膨張弁を介在させない設定である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the embodiment shown here, the setting is such that no expansion valve is interposed.

（ａ）実施の形態１
まず、実施の形態１を図１，図２に示す。図２に示すように蒸発器５にはフランジ（第１フランジ）６が設けられており、フランジ６には図示しない２つの流路が形成されており、これらの流路は蒸発器５に繋がっている。一方、フランジ６と結合するためのフランジ（第２フランジ）３が設けられている。フランジ３には、流路１ａ，２ａを形成するためのための供給用配管１の端部と流出用配管２の端部とが接続されている。即ち、図１（ｂ）に示すフランジ３の貫通孔３ｄ，３ｅに供給用配管１の端部と流出用配管２の端部とが嵌合されている。 (A) Embodiment 1
First, the first embodiment is shown in FIGS. As shown in FIG. 2, the evaporator 5 is provided with a flange (first flange) 6, and two flow paths (not shown) are formed in the flange 6, and these flow paths are connected to the evaporator 5. ing. On the other hand, a flange (second flange) 3 for coupling with the flange 6 is provided. The flange 3 is connected to the end of the supply pipe 1 and the end of the outflow pipe 2 for forming the flow paths 1a and 2a. That is, the end of the supply pipe 1 and the end of the outflow pipe 2 are fitted into the through holes 3d and 3e of the flange 3 shown in FIG.

フランジ３にはボルト４を挿通するための取付孔に代えて、溝３ｂが形成されている。溝３ｂは、フランジ３の両側の外周面３ｃに、フランジ３の厚さ方向に沿って形成されている。この実施例では、溝３ｂは、フランジ３の上下面に対して斜めに形成されている。これらの溝３ｂに嵌め込まれたボルト４が、フランジ６に形成された図示しない雌ネジ部にねじ込まれている。ボルト４の頭部とフランジ３との間には、ボルト４に挿通された状態で平座金７が設けられている。   A groove 3b is formed in the flange 3 in place of a mounting hole for inserting the bolt 4 therethrough. The groove 3 b is formed on the outer peripheral surface 3 c on both sides of the flange 3 along the thickness direction of the flange 3. In this embodiment, the groove 3 b is formed obliquely with respect to the upper and lower surfaces of the flange 3. Bolts 4 fitted in these grooves 3 b are screwed into female screw portions (not shown) formed in the flange 6. A flat washer 7 is provided between the head of the bolt 4 and the flange 3 while being inserted through the bolt 4.

フランジ６には図示しない一対の流路が形成されており、フランジ６の接合面には、一対の流路のうちの一方が開口する凸部６ｆが形成されている。また、フランジ３の接合面には、凸部６ｆを嵌め込むための凹部３ｈが形成されている。凹部３ｈは、フランジ３の貫通孔３ｄに供給用配管１の端部を嵌合した状態の、供給用配管１の端面の位置まで形成されている。そして、凸部６ｆの外周面には円周溝が形成され、該円周溝にシール材としてのＯリング８ｃが嵌め込まれている。なお、供給用配管１との関係で、フランジ３とフランジ６との接合面の凹凸構造について説明したが、流出用配管２についても接合面では同様な凹凸構造なので、説明を省略する。   A pair of flow paths (not shown) are formed in the flange 6, and a convex portion 6 f in which one of the pair of flow paths opens is formed on the joint surface of the flange 6. Further, a recess 3 h for fitting the protrusion 6 f is formed on the joint surface of the flange 3. The recess 3 h is formed up to the position of the end surface of the supply pipe 1 in a state where the end of the supply pipe 1 is fitted in the through hole 3 d of the flange 3. A circumferential groove is formed on the outer peripheral surface of the convex portion 6f, and an O-ring 8c as a sealing material is fitted in the circumferential groove. In addition, although the uneven structure of the joint surface of the flange 3 and the flange 6 was demonstrated by the relationship with the supply pipe | tube 1, since it is the same uneven structure in the joint surface also about the outflow pipe 2, description is abbreviate | omitted.

次に、配管フランジの作用を説明する。蒸発器５に供給用配管１と流出用配管２とを接続するには、図２に示すように、凸部６ｆを凹部３ｈに嵌め込んでフランジ３とフランジ６とを接合させたあとに、夫々平座金７を装着したボルト４をフランジ３の上下の溝３ｂに上下方向から嵌め込み、ボルト４を雌ネジ部にねじ込む。ボルト４をフランジ３の取付孔に挿通する作業がないので、手が供給用配管１と流出用配管２との間に入らなくてもよく、溝３ｂに嵌め込んだボルト４をそのまま図示しない雌ネジ部にねじ込めばよい。フランジ６にフランジ３を結合して供給用配管１と流出用配管２とを蒸発器５に接続する作業が円滑に行なえる。   Next, the operation of the piping flange will be described. In order to connect the supply pipe 1 and the outflow pipe 2 to the evaporator 5, as shown in FIG. 2, after fitting the convex portion 6 f into the concave portion 3 h and joining the flange 3 and the flange 6, The bolts 4 each fitted with the flat washer 7 are fitted into the upper and lower grooves 3b of the flange 3 from the upper and lower directions, and the bolts 4 are screwed into the female screw portions. Since there is no work for inserting the bolt 4 into the mounting hole of the flange 3, the hand does not have to be inserted between the supply pipe 1 and the outflow pipe 2, and the bolt 4 fitted in the groove 3b is not shown as it is. Just screw it into the thread. The operation of connecting the flange 3 to the flange 6 and connecting the supply pipe 1 and the outflow pipe 2 to the evaporator 5 can be performed smoothly.

（ｂ）実施の形態２
次に、実施の形態２を図３に示す。この実施の形態は、フランジ３に形成する溝３ｂの形状のみが、実施の形態１と異なる。本実施の形態では、溝３ｂは、外周面３ｃに対して略直角に形成されている。 (B) Embodiment 2
Next, Embodiment 2 is shown in FIG. This embodiment is different from the first embodiment only in the shape of the groove 3 b formed in the flange 3. In the present embodiment, the groove 3b is formed substantially perpendicular to the outer peripheral surface 3c.

その他の構成，作用は実施の形態１と同じなので、説明を省略する。   Since other configurations and operations are the same as those of the first embodiment, description thereof is omitted.

（ｃ）実施の形態３
最後に、実施の形態３を図４に示す。この実施の形態は、フランジ３の貫通孔３ｄ，３ｅに嵌合した供給用配管１と流出用配管２との端部を反対側まで貫通させることにより、フランジ３の接合面から突出する凸部３ｆ，３ｇに流路１ａ，２ａを開口させたものである。一方、フランジ６には流路６ｂ，６ｃが形成されており、流路６ｂ，６ｃの開口する凹部６ｄ，６ｅがフランジ３との接合面に形成されている。そして、凸部３ｆ，３ｇの外周面には円周溝が形成され、該円周溝にシール材としてのＯリング８ａ，８ｂが嵌め込まれている。 (C) Embodiment 3
Finally, Embodiment 3 is shown in FIG. In this embodiment, a protruding portion that protrudes from the joint surface of the flange 3 by penetrating the ends of the supply pipe 1 and the outflow pipe 2 fitted in the through holes 3d and 3e of the flange 3 to the opposite side. The flow paths 1a and 2a are opened in 3f and 3g. On the other hand, flow paths 6 b and 6 c are formed in the flange 6, and recesses 6 d and 6 e opened in the flow paths 6 b and 6 c are formed on the joint surface with the flange 3. And the circumferential groove is formed in the outer peripheral surface of convex part 3f, 3g, and O-ring 8a, 8b as a sealing material is inserted in this circumferential groove.

フランジ３をフランジ６に結合する際には、凸部３ｆ，３ｇを凹部６ｄ，６ｅに嵌め込む。すると、Ｏリング８ａ，８ｂが凸部３ｆ，３ｇの外周面と凹部６ｄ，６ｅの内周面との間を気密に封鎖するので、ボルト４を強く締め付けることなく流路６ｂ，６ｃと流路１ａ，２ａとの連通を気密に行なうことができる。   When the flange 3 is coupled to the flange 6, the convex portions 3f and 3g are fitted into the concave portions 6d and 6e. Then, the O-rings 8a and 8b hermetically seal between the outer peripheral surfaces of the convex portions 3f and 3g and the inner peripheral surfaces of the concave portions 6d and 6e. Communication with 1a and 2a can be performed airtightly.
