Description
【０００１】0001
本考案は、平面形状が多角形をなして延び、対向する二部材間に圧縮状態に介 在して密封を行なう中空の金属シールに関する。 The present invention has a planar shape that extends into a polygon, and mediates a compressed state between two opposing members. This invention relates to a hollow metal seal that is placed in the air to provide a hermetic seal.
【０００２】0002
従来から、図３及び図４に示すように、各頂点となる屈曲部２がアール状であ る略多角形（図では略正方形）の平面形状をなして延び、例えば圧力容器４を構 成する対向する二部材のフランジ５，６間に形成された溝部７内に介装され、前 記両フランジ５，６に適宜圧縮されて密封を行なう断面円形の中空金属シール１ が知られている。 Conventionally, as shown in FIGS. 3 and 4, the bending portion 2 serving as each vertex is rounded. It extends in a substantially polygonal (approximately square in the figure) planar shape, and is used for constructing the pressure vessel 4, for example. The front A hollow metal seal 1 with a circular cross section is compressed appropriately to the flanges 5 and 6 for sealing. It has been known.
【０００３】0003
しかしながら、上記従来構造によると、屈曲部２は、多角形の各辺に相当する 部分である非屈曲部３に比較して、両フランジ５，６からの圧縮荷重に対する弾 性係数がきわめて大きいため、非屈曲部３にも適切な締め代を付与するためには 屈曲部２に対する両フランジ５，６の締め付け力を大きくする必要があり、また フランジ５，６との圧接力が非屈曲部３よりも屈曲部２で著しく大きくなること から、フランジ５，６の対向面に不均一な歪が発生して密封性に悪影響を及ぼし ていた。 However, according to the above conventional structure, the bent portions 2 correspond to each side of the polygon. The elasticity against the compressive load from both flanges 5 and 6 is higher than that of the non-bent portion 3. Since the elasticity coefficient is extremely large, in order to provide an appropriate interference to the non-bent portion 3, It is necessary to increase the tightening force of both flanges 5 and 6 to the bent part 2, and The pressure contact force with the flanges 5 and 6 is significantly larger in the bent portion 2 than in the non-bent portion 3. As a result, uneven distortion occurs on the opposing surfaces of flanges 5 and 6, which adversely affects sealing performance. was.
【０００４】 そこで本考案は、上記した問題に鑑み、各屈曲部における圧縮荷重に対する弾 性係数を低下させるとともに、密封性を安定させることを課題としてなされたも のである。0004 Therefore, in view of the above-mentioned problems, the present invention has been developed to provide elasticity against compressive loads at each bend. This was done with the aim of lowering the sealing coefficient and stabilizing the sealing performance. It is.

上記課題を解決するため、本考案は、平面形状が略多角形をなして延びる断面 円形の中空の金属シールにおいて、多角形の各頂点部分に相当する各屈曲部の屈 曲方向内側又は外側に、当該シールの長さ方向に延びるスリットをそれぞれ形成 したものである。 In order to solve the above problems, the present invention has developed a cross-section whose planar shape extends substantially in the form of a polygon. In a circular hollow metal seal, each bend corresponds to each vertex of the polygon. A slit extending in the length direction of the seal is formed on the inside or outside in the bending direction. This is what I did.
【０００６】[0006]
上記構成によると、圧縮荷重に対する各屈曲部の弾性係数は、その屈曲方向内 側又は外側に当該シールの長さ方向に延びるスリットが形成されたことによって 著しく低下する。 According to the above configuration, the elastic modulus of each bent part against compressive load is within the bending direction. By forming a slit extending in the length direction of the seal on the side or outside, Significantly decreased.
【０００７】 また、前記スリットを通じて、当該中空金属シールの中空部内に密封対象流体 の圧力を導入することによって、セルフシール作用を与えることができる。[0007] Also, the fluid to be sealed is inserted into the hollow part of the hollow metal seal through the slit. A self-sealing effect can be provided by introducing a pressure of .
【０００８】[0008]
次に、本考案の中空金属シールを図１及び図２に示す一実施例を参照しながら 説明すると、この中空金属シール１１は、平面形状が略正方形をなして延びるも のであって、この正方形の各頂点部分に相当するアール状の各屈曲部１２の屈曲 方向内側には、それぞれ当該中空金属シール１１の長さ方向へ延びる有端のスリ ット１４が形成されている。すなわち、各辺に相当する非屈曲部１３の断面形状 は、図４に示す従来例と同様に連続した円周をなすが、前記屈曲部１２の断面形 状は、スリット１４の存在によって略Ｃ字形をなしている。 Next, referring to an embodiment of the hollow metal seal of the present invention shown in FIGS. 1 and 2, To explain, this hollow metal seal 11 has a substantially square planar shape and extends. The bending of each rounded bent portion 12 corresponding to each vertex of this square On the inner side of the hollow metal seal 11 is a slot with an end extending in the length direction of the hollow metal seal 11. A cut 14 is formed. That is, the cross-sectional shape of the non-bent portion 13 corresponding to each side forms a continuous circumference similar to the conventional example shown in FIG. 4, but the cross-sectional shape of the bent portion 12 The shape is approximately C-shaped due to the presence of the slit 14.
【０００９】 このような中空金属シール１１は、円形断面の金属パイプを等間隔おいた部分 でそれぞれ同方向へ屈曲して、対向した両端を互いに溶接してから、屈曲部１２ にカッタ装置でスリット１４を切設することによって製造される。[0009] Such a hollow metal seal 11 is made of metal pipes with a circular cross section spaced at equal intervals. After bending in the same direction and welding the opposing ends to each other, the bent portion 12 is bent in the same direction. It is manufactured by cutting a slit 14 with a cutter device.
【００１０】 上記構成の中空金属シール１１は、図２に示すように例えば圧力容器４を構成 する対向する二部材のフランジ５，６間に形成された溝部７内に介装されるもの で、前記両フランジ５，６からの圧縮荷重に対する屈曲部１２は、スリット１４ の存在によって円形断面の従来のものよりも弾性係数が低下する。このため、屈 曲部１２と非屈曲部１３の弾性係数の差を緩和して均一化することができ、フラ ンジ５，６の不均一な歪を防止することができる。0010 The hollow metal seal 11 configured as described above constitutes a pressure vessel 4, for example, as shown in FIG. Interposed in the groove 7 formed between the flanges 5 and 6 of the two opposing members. The bending portion 12 against the compressive load from both flanges 5 and 6 has a slit 14. Due to the presence of , the elastic modulus is lower than that of the conventional one with a circular cross section. For this reason, The difference in elastic modulus between the bent portion 12 and the non-bent portion 13 can be relaxed and made uniform, and the flap This makes it possible to prevent uneven distortion of the hinges 5 and 6.
【００１１】 また、この実施例によると、スリット１４が屈曲部１２の屈曲方向内側に開口 しているため、とくに内圧用シールとして有用である。すなわち図２の装着状態 において、容器内室８の密封対象流体による内圧Ｐがスリット１４を通じて中空 部１５に導入されるので、この内圧Ｐによるセルフシール作用が生じ、しかも、 このセルフシール作用はスリット１４の存在しない非屈曲部１３にも等しく生じ ることから、安定したシール性が得られる。[0011] Further, according to this embodiment, the slit 14 is opened on the inside of the bent portion 12 in the bending direction. This makes it particularly useful as an internal pressure seal. In other words, the installed state shown in Figure 2 In this case, the internal pressure P due to the fluid to be sealed in the container inner chamber 8 is applied to the hollow space through the slit 14. Since it is introduced into the section 15, a self-sealing effect occurs due to this internal pressure P, and furthermore, This self-sealing effect occurs equally in the non-bent portion 13 where the slit 14 is not present. As a result, stable sealing performance can be obtained.
【００１２】 なお、図示の実施例は、平面形状が略正方形のものについて本考案を適用した が、略長方形をなすものなど、他の多角形状であっても同様に構成することがで きることは勿論であり、また、圧縮荷重に対する屈曲部１２の弾性係数低下の度 合は、スリット１４の溝幅及び長さによって任意に設定可能であり、スリット１ ４は図示の例とは逆に屈曲方向外側に形成することによって、外圧用としてとく に有用なシールとすることができる。0012 Note that the illustrated embodiment is an example in which the present invention is applied to an object whose planar shape is approximately square. However, other polygonal shapes, such as those that are approximately rectangular, can be constructed in the same way. Of course, it is possible to The case can be arbitrarily set depending on the groove width and length of the slit 14. 4 is designed for external pressure by forming it on the outside in the bending direction, contrary to the illustrated example. It can be a useful seal.
【００１３】[0013]
以上、本考案によると、圧縮荷重に対する各屈曲部の弾性係数は、スリットの 存在によって低下するので、非屈曲部に締め代を付与するための締め付け力を軽 減することが可能になるとともに、屈曲部と非屈曲部の弾性係数の差が緩和され て相手部材の接触面の不均一な歪を防止することができ、さらに、セルフシール 機能が得られて優れた密封性を発揮するものである。 As described above, according to the present invention, the elastic modulus of each bending part against compressive load is Therefore, the tightening force used to add a tightening allowance to non-bent parts should be reduced. At the same time, the difference in elastic modulus between the bent and non-bent parts is alleviated. This prevents uneven distortion of the contact surface of the mating member, and also allows for self-sealing. It is functional and exhibits excellent sealing performance.
