Description

本発明は、圧力容器に関する。   The present invention relates to a pressure vessel.

筒状のシリンダ部と当該シリンダ部に連続するドーム部とを有するライナーと、ライナーの外側にフィラメントワインディングのフープ巻きと低角度ヘリカル巻き（インプレーン巻きを含む）と高角度ヘリカル巻きとで形成される繊維補強材と、を有する圧力容器が知られている（例えば、特許文献１参照）。   A liner having a cylindrical cylinder portion and a dome portion continuous with the cylinder portion, and formed by hoop winding of a filament winding on the outside of the liner, low angle helical winding (including in-plane winding) and high angle helical winding There is known a pressure vessel having a fiber reinforcing material (see, for example, Patent Document 1).

フープ巻きは、図４（ａ）に示すように繊維補強材３０を圧力容器３１の軸心Ｏと略直交する方向に巻く巻き方であり、低角度ヘリカル巻きは、図４（ｂ）に示すように軸心Ｏに対して低い配向角度θ２で巻く巻き方であり、高角度ヘリカル巻きは、図４（ｃ）に示すように軸心Ｏに対して高い配向角度θ１で巻く巻き方である。一般に、フープ巻きはシリンダ部３２（すなわち径方向の耐圧性）を補強する目的で行われ、低角度ヘリカル巻きはドーム部３３（すなわち軸方向の耐圧性）を補強する目的で行われ、高角度ヘリカル巻きはフープ巻きや低角度ヘリカル巻きでは補強しきれない部位、すなわちドーム部３３のシリンダ部３２寄りの部位である肩部３５を補強する目的で行われている。   The hoop winding is a method of winding the fiber reinforcing material 30 in a direction substantially orthogonal to the axis O of the pressure vessel 31 as shown in FIG. 4A, and the low angle helical winding is shown in FIG. As shown in FIG. 4C, the high angle helical winding is wound at a high orientation angle θ1 with respect to the axial center O. . Generally, hoop winding is performed for the purpose of reinforcing the cylinder portion 32 (that is, pressure resistance in the radial direction), and low angle helical winding is performed for the purpose of reinforcing the dome portion 33 (that is, pressure resistance in the axial direction). The helical winding is performed for the purpose of reinforcing a portion which can not be reinforced by hoop winding or low angle helical winding, that is, a shoulder 35 which is a portion closer to the cylinder portion 32 of the dome portion 33.

特開２０１２−２４６９６２号公報JP 2012-246962

一般に圧力容器のフィラメントワインディング法は、図５に示すように圧力容器３１を軸心Ｏ周りに回転させつつ、ロービング供給機４１を軸心Ｏに沿って往復動させて繊維補強材をライナーに巻き付けていく。フープ巻きは軸心Ｏと略直交する方向に巻くので、シリンダ部３２の任意の箇所でロービング供給機４１を反転させることができるが、高角度ヘリカル巻きは配向角度があるので、両ドーム部３３でロービング供給機４１を反転させる必要がある。つまり、高角度ヘリカル巻きは肩部３５のみならず両ドーム部３３の間に位置するシリンダ部３２にも必ず適用されることとなる。   Generally, as shown in FIG. 5, the filament winding method of the pressure vessel reciprocates the roving feeder 41 along the axis O while rotating the pressure vessel 31 around the axis O to wind the fiber reinforcement on the liner. To go. Since the hoop winding is performed in a direction substantially orthogonal to the axial center O, the roving feeder 41 can be reversed at any position of the cylinder portion 32. However, since the high angle helical winding has an orientation angle, both dome portions 33 It is necessary to invert the roving feeder 41. That is, the high angle helical winding is applied not only to the shoulder portion 35 but also to the cylinder portion 32 located between the dome portions 33.

しかし、高角度ヘリカル巻きは、前記したように主にドーム部３３の肩部３５を補強する目的で行われるものであり、シリンダ部３２での高角度ヘリカル巻きの補強効率はフープ巻きに比べると低い。すなわち、高角度ヘリカル巻きは、肩部３５の補強のため不可欠であるものの、従来では補強効率の低いシリンダ部３２にも必ず適用されるため、無駄の多い巻き方となっていた。これは、シリンダ部３２が長尺な圧力容器３１ほど顕著な問題となる。   However, the high angle helical winding is mainly performed for the purpose of reinforcing the shoulder portion 35 of the dome portion 33 as described above, and the reinforcing efficiency of the high angle helical winding in the cylinder portion 32 is compared to the hoop winding. Low. That is, although high-angle helical winding is indispensable for reinforcement of the shoulder 35, conventionally it has always been applied to the cylinder portion 32 with low reinforcement efficiency, so it has been a wasteful winding method. This becomes a more serious problem as the cylinder portion 32 is a longer pressure vessel 31.

本発明はこのような課題を解決するために創作されたものであり、高角度ヘリカル巻きをドーム部に効率良く形成できる圧力容器を提供することを目的とする。   The present invention is created to solve such problems, and an object of the present invention is to provide a pressure vessel in which high-angle helical winding can be efficiently formed on a dome portion.

前記課題を解決するため、本発明は、流体を収容可能であって筒状のシリンダ部と当該シリンダ部に連続するドーム部とを有するライナーと、前記ライナーの外側に、フープ巻きで形成したフープ層と、低角度ヘリカル巻きで形成した低角度ヘリカル層と、高角度ヘリカル巻きで形成した高角度ヘリカル層と、を有して構成される繊維補強材と、を備える圧力容器であって、前記ライナーの前記ドーム部から前記シリンダ部に向かう途中に、軸心に向けて変位する引掛け部が形成され、前記ドーム部と前記引掛け部とを利用して局所的に形成される前記高角度ヘリカル層を少なくとも有することを特徴とする。   In order to solve the above-mentioned problems, the present invention is a liner which is capable of containing a fluid and which has a cylindrical cylinder portion and a dome portion continuing to the cylinder portion, and a hoop formed by hoop winding outside the liner. A pressure vessel comprising a fiber reinforcement comprising a layer, a low angle helical layer formed by low angle helical winding, and a high angle helical layer formed by high angle helical winding, On the way from the dome portion to the cylinder portion of the liner, a hook portion that is displaced toward the axial center is formed, and the high angle locally formed using the dome portion and the hook portion It is characterized in that it has at least a helical layer.

本発明によれば、ドーム部からシリンダ部に向かう途中に、軸心に向けて変位する引掛け部を形成し、高角度ヘリカル層を、ドーム部と引掛け部とを利用して局所的に形成したことにより、高角度ヘリカル層を、シリンダ部に形成することなく、所定のドーム部のみに形成することができる。これにより、ドーム部の補強を主目的とする高角度ヘリカル巻きにおいてシリンダ部への無駄巻きを解消できる。   According to the present invention, the hook portion which is displaced toward the axial center is formed on the way from the dome portion to the cylinder portion, and the high angle helical layer is locally used by utilizing the dome portion and the hook portion. By forming the high angle helical layer, it is possible to form only the predetermined dome portion without forming the high angle helical layer in the cylinder portion. As a result, it is possible to eliminate useless winding on the cylinder in high-angle helical winding mainly for reinforcement of the dome.

また、本発明は、前記ドーム部と前記シリンダ部との間に、シリンダ部の外面よりも径外方向に張り出す凸状部が形成され、当該凸状部の前記シリンダ部寄りに形成された引掛け斜面が前記引掛け部を構成することを特徴とする。   Further, according to the present invention, a convex portion protruding outward in a radial direction from the outer surface of the cylinder portion is formed between the dome portion and the cylinder portion, and the convex portion is formed closer to the cylinder portion. A hook slope constitutes the hook portion.

本発明によれば、ドーム部とシリンダ部との間に凸状部を形成することで、この凸状部の斜面を引掛け部に利用できるので、ライナーの形状をさほど複雑にすることなく簡単な構造で引掛け部を形成できる。   According to the present invention, by forming the convex portion between the dome portion and the cylinder portion, the slope of this convex portion can be used as the hooking portion, so the shape of the liner can be simplified without much complication. The hook portion can be formed with the following structure.

また、本発明は、前記凸状部と前記ドーム部との間に段差部が形成され、前記高角度ヘリカル層の外面と前記ドーム部の外面とが面一に形成されていることを特徴とする。   Further, the present invention is characterized in that a stepped portion is formed between the convex portion and the dome portion, and the outer surface of the high angle helical layer and the outer surface of the dome portion are formed flush. Do.

本発明によれば、高角度ヘリカル層の外面をドーム部の外面と面一にすることができる。したがって、高角度ヘリカル層の外面とドーム部の外面とにわたり低角度ヘリカル層を形成したとしても隙間は生じず、繊維補強材を密に巻くことができる。   According to the present invention, the outer surface of the high angle helical layer can be made flush with the outer surface of the dome portion. Therefore, even if a low angle helical layer is formed between the outer surface of the high angle helical layer and the outer surface of the dome portion, no gap is generated, and the fiber reinforcement can be tightly wound.

本発明によれば、高角度ヘリカル巻きをドーム部に効率良く形成できる。   According to the present invention, high angle helical winding can be efficiently formed on the dome portion.

本発明の圧力容器はＬＰＧ等の低圧ガス、水素ガス等の高圧ガス、その他の流体を貯留する容器として適用できる。図１に示すように、本発明の圧力容器１は、ライナー２と、ライナー２の表面にフィラメントワインディングにより形成される繊維補強材１１とを有する。   The pressure vessel of the present invention can be applied as a vessel for storing low pressure gas such as LPG, high pressure gas such as hydrogen gas, and other fluids. As shown in FIG. 1, the pressure vessel 1 of the present invention has a liner 2 and a fiber reinforcement 11 formed on the surface of the liner 2 by filament winding.

ライナー２は、略定断面の円筒状のシリンダ部３と、シリンダ部３の両端に形成されるドーム部４，４とを有する。各ドーム部４の頂上にはそれぞれ圧力容器１の軸心Ｏと同軸状にライナーネック５が突設され、ライナーネック５の外周には金属製の口金６がライナー２と一体成形されている。ライナー２は例えばポリエチレン等の合成樹脂材から構成され、インジェクション成形やブロー成形等により形成されている。   The liner 2 has a cylindrical cylinder portion 3 having a substantially constant cross section, and dome portions 4 formed at both ends of the cylinder portion 3. A liner neck 5 is provided on the top of each dome 4 so as to be coaxial with the axis O of the pressure vessel 1, and a metal cap 6 is integrally formed with the liner 2 on the outer periphery of the liner neck 5. The liner 2 is made of, for example, a synthetic resin material such as polyethylene, and is formed by injection molding, blow molding or the like.

ドーム部４は、シリンダ部３の端部から曲面状に縮径する肩部４Ａと、肩部４Ａの先端側に形成され軸心Ｏとの略直交面をなす平面部４Ｂとを有した形状からなる。場合により、平面部４Ｂを形成することなく、シリンダ部３の端部からライナーネック５にかけて全て曲面状に縮径形成してもよい。   The dome portion 4 has a shoulder portion 4A whose diameter is reduced in a curved shape from an end of the cylinder portion 3 and a flat portion 4B which is formed on the tip end side of the shoulder portion 4A and which forms a substantially orthogonal plane with the axis O It consists of In some cases, the diameter may be reduced in a curved shape from the end of the cylinder portion 3 to the liner neck 5 without forming the flat portion 4B.

繊維補強材１１は、含浸処理されたストランドの束からなるロービングとされたうえで、図示しない回転装置により軸心Ｏ回りに回転するライナー２の外面に巻き付けられる。繊維補強材１１は、フープ巻きで形成したフープ層１２と、低角度ヘリカル巻きで形成した低角度ヘリカル層１３と、高角度ヘリカル巻きで形成した高角度ヘリカル層１４と、を有して構成されている。   The fiber reinforcing material 11 is a roving made of a bundle of impregnated strands, and is wound around the outer surface of the liner 2 which rotates around the axis O by a rotating device (not shown). The fiber reinforcing material 11 includes a hoop layer 12 formed by hoop winding, a low angle helical layer 13 formed by low angle helical winding, and a high angle helical layer 14 formed by high angle helical winding. ing.

フープ巻きは、図４（ａ）で説明したように圧力容器の軸心Ｏと略直交する方向に巻く巻き方であり、低角度ヘリカル巻きは、図４（ｂ）で説明したように軸心Ｏに対して低い配向角度θ２で巻く巻き方であり、高角度ヘリカル巻きは、図４（ｃ）で説明したように軸心Ｏに対して高い配向角度θ１で巻く巻き方である。低角度ヘリカル巻きの配向角度θ２は、概ねライナーネック５に掛け回し可能な最小角度以上で１５°以下の範囲であり、高角度ヘリカル巻きの配向角度θ１は、概ね軸心Ｏに対し６５°〜７５°の範囲である。   The hoop winding is wound in a direction substantially orthogonal to the axial center O of the pressure vessel as described in FIG. 4A, and the low angle helical winding is an axial center as described in FIG. 4B. The winding is performed at a low orientation angle θ2 with respect to O, and the high-angle helical winding is wound at a high orientation angle θ1 with respect to the axial center O as described with reference to FIG. The orientation angle θ2 of the low angle helical winding is generally in the range of not less than the minimum angle that can be wound around the liner neck 5 and 15 ° or less, and the orientation angle θ1 of the high angle helical winding is generally 65 ° to the axis O It is in the range of 75 °.

「引掛け部７」
図２に示すように、側断面視において、ライナー２のドーム部４からシリンダ部３に向かう途中には、軸心Ｏに向けて変位する引掛け部７が形成されている。本実施形態では、ドーム部４とシリンダ部３との間の肩部４Ａに、シリンダ部３の外面３Ａよりも径外方向に張り出す凸状部８が形成され、この凸状部８のシリンダ部３寄りに形成された引掛け斜面８Ａが引掛け部７を構成する。凸状部８は、曲面状の山形を呈しており、頂上部８Ｂを境にシリンダ部３寄りに引掛け斜面８Ａが形成され、ドーム部４寄りにドーム延長斜面８Ｃが形成されている。軸心Ｏ方向に沿う引掛け斜面８Ａの長さＬ１とドーム延長斜面８Ｃの長さＬ２とは略等しく形成されている。"Hatch part 7"
As shown in FIG. 2, a hook 7 that is displaced toward the axial center O is formed on the way from the dome 4 of the liner 2 to the cylinder 3 in a side sectional view. In the present embodiment, the shoulder 4A between the dome 4 and the cylinder 3 is formed with a convex 8 projecting radially outward from the outer surface 3A of the cylinder 3. The cylinder of the convex 8 The hooking slope 8A formed closer to the part 3 constitutes the hooking part 7. The convex portion 8 has a curved chevron shape, and a hook slope 8A is formed on the side of the cylinder portion 3 with the top 8B as a boundary, and a dome extension slope 8C is formed on the dome 4 side. The length L1 of the hooking slope 8A along the axial center O direction and the length L2 of the dome extension slope 8C are substantially equal.

すなわち、従来、ドーム部４の外面はシリンダ部３に向かうにしたがい曲面状に漸次拡径し、最も拡径したところが定径断面のシリンダ部３の端部を構成していた。これに対し本発明の圧力容器１は、ドーム部４の外面は凸状部８の頂上部８Ｂまでは概ね拡径していくが、頂上部８Ｂからシリンダ部３寄りの範囲は、引掛け斜面８Ａによって、シリンダ部３に向かうにしたがい漸次縮径するように形成されている。   That is, conventionally, the outer surface of the dome portion 4 is gradually diameter-expanded in a curved surface shape toward the cylinder portion 3, and the portion of the diameter diameter expanded most constitutes the end portion of the cylinder portion 3 of the constant diameter cross section. On the other hand, in the pressure vessel 1 of the present invention, the diameter of the outer surface of the dome portion 4 is generally expanded to the top 8B of the convex portion 8, but the range closer to the cylinder 3 from the top 8B is a hook slope By 8A, it is formed so that it may be gradually diameter-reduced as it goes to the cylinder part 3. As shown in FIG.

以上のように、ドーム部４からシリンダ部３に向かう途中に、軸心Ｏに向けて変位する引掛け斜面８Ａを形成したことにより、一方のドーム部４における高角度ヘリカル巻きのヘリカル方向（螺旋方向）を、従来のように他方のドーム部４で変えることなく、引掛け斜面８Ａで変えることができる。つまり、ドーム延長斜面８Ｃと引掛け斜面８Ａとを利用して高角度ヘリカル層１４を局所的に形成できる。これにより、高角度ヘリカル層１４を、シリンダ部３に形成することなく、肩部４Ａに形成した凸状部８のみに形成することができ、肩部４Ａの補強を主目的とする高角度ヘリカル巻きにおいてシリンダ部３への無駄巻きを解消できる。高角度ヘリカル層１４は凸状部８の曲面に倣って円弧状に形成される。   As described above, by forming the hook slope 8A displaced toward the axial center O on the way from the dome portion 4 to the cylinder portion 3, the helical direction of the high angle helical winding in one dome portion 4 (helix The direction can be changed at the hook slope 8A without changing the other dome portion 4 as in the prior art. That is, the high angle helical layer 14 can be locally formed using the dome extension slope 8C and the hook slope 8A. As a result, the high angle helical layer 14 can be formed only on the convex portion 8 formed on the shoulder 4A without being formed on the cylinder portion 3, and a high angle helical mainly intended to reinforce the shoulder 4A. It is possible to eliminate useless winding on the cylinder portion 3 in winding. The high angle helical layer 14 is formed in an arc shape following the curved surface of the convex portion 8.

フープ層１２、低角度ヘリカル層１３、高角度ヘリカル層１４の形成順序は、高角度ヘリカル層１４が最初に形成され、次いで、フープ層１２、低角度ヘリカル層１３の順に形成されている。フープ層１２は、シリンダ部３を補強するべくシリンダ部３の外面３Ａに形成されており、本実施形態では図２に示すように、その端部は、斜面８Ａ上に形成された高角度ヘリカル層１４の外面を覆うように形成されている。フープ層１２の外面と、ドーム延長斜面８Ｃ上に形成された高角度ヘリカル層１４の外面とは面一状に形成される。   In the formation order of the hoop layer 12, the low angle helical layer 13, and the high angle helical layer 14, the high angle helical layer 14 is formed first, and then the hoop layer 12 and the low angle helical layer 13 are formed in this order. The hoop layer 12 is formed on the outer surface 3A of the cylinder portion 3 to reinforce the cylinder portion 3. In the present embodiment, as shown in FIG. 2, the end portion thereof is a high angle helical formed on the slope 8A. It is formed to cover the outer surface of the layer 14. The outer surface of the hoop layer 12 and the outer surface of the high angle helical layer 14 formed on the dome extension slope 8C are formed flush with each other.

最後に形成される低角度ヘリカル層１３は、圧力容器１全体にわたって形成される層であり、フープ層１２、高角度ヘリカル層１４の各外面と、未だむき出し状態となっているドーム部４のライナー２の外面とを覆うように形成される。なお、低角度ヘリカル層１３において、低角度ヘリカル巻きを施した後、シリンダ部３の範囲にさらなる補強としてフープ巻きを施してもよいし、高角度ヘリカル巻きを多少混在させてもよい。   The low angle helical layer 13 to be formed last is a layer formed over the entire pressure vessel 1, and the outer surface of each of the hoop layer 12 and the high angle helical layer 14 and the liner of the dome portion 4 still exposed. It is formed to cover the outer surface of 2. In the low angle helical layer 13, after applying low angle helical winding, hoop winding may be applied to the area of the cylinder portion 3 as a further reinforcement, or high angle helical winding may be mixed to some extent.

ここで、図３に示すように、凸状部８をドーム部４の外面に対して滑らかに形成した場合、高角度ヘリカル層１４の外面とドーム部４の外面との間に段差が生じるので、低角度ヘリカル層１３を形成すると、ドーム部４と高角度ヘリカル層１４と低角度ヘリカル層１３との間に隙間Ｓが形成されることがある。これに対し、図２に示すように、凸状部８とドーム部４との間に、凸状部８がドーム部４よりも圧力容器１の内側に位置するような段差部９を形成すれば、高角度ヘリカル層１４の外面をドーム部４の外面と面一にすることができる。これにより、高角度ヘリカル層１４の外面とドーム部４の外面とにわたり低角度ヘリカル層１３を形成しても前記隙間Ｓは生じず、繊維補強材１１を密に巻くことができる。   Here, as shown in FIG. 3, when the convex portion 8 is formed smoothly with respect to the outer surface of the dome portion 4, a step is generated between the outer surface of the high angle helical layer 14 and the outer surface of the dome portion 4. When the low angle helical layer 13 is formed, a gap S may be formed between the dome portion 4, the high angle helical layer 14, and the low angle helical layer 13. On the other hand, as shown in FIG. 2, a step 9 is formed between the convex portion 8 and the dome portion 4 such that the convex portion 8 is positioned on the inner side of the pressure vessel 1 than the dome portion 4. For example, the outer surface of the high angle helical layer 14 can be flush with the outer surface of the dome portion 4. As a result, even if the low angle helical layer 13 is formed over the outer surface of the high angle helical layer 14 and the outer surface of the dome portion 4, the gap S does not occur, and the fiber reinforcing material 11 can be tightly wound.
