Description
【０００１】[0001]
この考案は、２つの部材間を弾性パッキンでシールする弾性パッキンを有する フランジ部シール構造に関する。 The present invention relates to a flange seal structure having an elastic packing that seals between two members with an elastic packing.
【０００２】[0002]
従来の弾性パッキンを有するフランジ部シール構造は、図５、６のように部材 ２０の端部外周にフランジ２３が設けられ、該フランジ２３の下面２４の略中央 に角形のパッキン溝２５が形成され、その外方の一方面にはボルト孔２９を設け たものである。そして、パッキン溝２５には断面が角形の弾性パッキン２２が、 ボルト孔２９には取付ボルト２７が設けられている。 In a conventional flange seal structure having an elastic packing, a flange 23 is provided on the outer periphery of the end of the member 20 as shown in FIGS. 5 and 6, and a rectangular packing groove 25 is formed in the lower surface 24 of the flange 23 substantially at the center. A bolt hole 29 is provided on one outer surface thereof. An elastic packing 22 having a square cross section is provided in the packing groove 25, and a mounting bolt 27 is provided in the bolt hole 29.
【０００３】 部材２０と部材２１は、取付ボルト２７で締付けられ、弾性パッキン２２が部 材２１の上面２６に嵌着される。The member 20 and the member 21 are tightened with a mounting bolt 27, and the elastic packing 22 is fitted on the upper surface 26 of the member 21.
【０００４】[0004]
図５、６において、取付ボルト２７を締付けると弾性パッキン２２は、圧縮さ れ部材２１の上面２６との当接部より上向方向の反力を受ける。この反力は、パ ッキン溝２５の上壁２８に作用する。そうすると、上向方向の反力によってフラ ンジ２３が変形してしまい、弾性パッキン２２と部材２１の上面２６との間に隙 間が生じシール不良に至る恐れがある。 In FIGS. 5 and 6, when the mounting bolt 27 is tightened, the elastic packing 22 receives a reaction force in the upward direction from the contact portion with the upper surface 26 of the compressed member 21. This reaction force acts on the upper wall 28 of the packing groove 25. Then, the flange 23 is deformed by the reaction force in the upward direction, and there is a possibility that a gap is created between the elastic packing 22 and the upper surface 26 of the member 21 and a sealing failure occurs.
【０００５】 このようなシール不良は、フランジ２３が熱可塑性樹脂でできており厚味が薄 い場合には顕著であり、使用環境が高温雰囲気下ではさらに顕著に生じる。Such a sealing failure is remarkable when the flange 23 is made of a thermoplastic resin and has a small thickness, and is more remarkable when the usage environment is a high temperature atmosphere.
【０００６】[0006]
一方の部材の端部外周にフランジを設け、該フランジの下面に環状の環状壁を 有し、その先端には球形状の突起部を形成するとともに、他方の部材の上面の外 周に環状の凹溝を設け、該凹溝には、環状であって上面に環状溝を有する弾性パ ッキンを装着し、環状溝に前記環状壁と突起部とを挿設した構成としたものであ る。 A flange is provided on the outer periphery of the end of one member, an annular wall is formed on the lower surface of the flange, and a spherical protrusion is formed at the tip of the flange, and an annular ring is formed on the outer periphery of the upper surface of the other member. A concave groove is provided, an elastic packing having an annular groove on the upper surface is attached to the concave groove, and the annular wall and the protrusion are inserted in the annular groove.
【０００７】[0007]
両部材が締結された後、たとえば高温雰囲気下で長時間使用されるとフランジ が変形し、突起部下端が弾性パッキンの環状溝の底面から離反することがある。 その場合でも、突起部と環状溝の内外周のシールは保持される。 After both members are fastened, the flange may be deformed and the lower end of the protrusion may be separated from the bottom surface of the annular groove of the elastic packing when used for a long time in a high temperature atmosphere, for example. Even in that case, the protrusion and the inner and outer seals of the annular groove are retained.

The groove height of the annular groove 11 is substantially the same as the height obtained by adding the respective heights of the annular wall 6 and the protruding portion 7, and the width thereof is substantially the same as the width of the annular wall 6.
【００１２】 また、弾性パッキン３の環状溝１１は、図４のように断面アリ溝状としても良 い。Further, the annular groove 11 of the elastic packing 3 may have a dovetail groove cross section as shown in FIG.
【００１３】 弾性パッキン３は、部材２の凹溝９に装着された後、部材１の環状部６と突起 部７とが弾性パッキン３の環状溝１１に挿設される。そして、部材１のボルト孔 １３に取付ボルト１２を挿通し部材１と部材２が締結される。After the elastic packing 3 is mounted in the concave groove 9 of the member 2, the annular portion 6 and the protruding portion 7 of the member 1 are inserted in the annular groove 11 of the elastic packing 3. Then, the mounting bolt 12 is inserted into the bolt hole 13 of the member 1 and the member 1 and the member 2 are fastened.
