煙道用継手及び煙道用継手の製造方法並びに煙道用継手の部分成形装置

Flue joint and manufacture thereof, and forming device of flue joint part

Abstract

(57)【要約】 【目的】 煙道用継手の製造効率を向上させるととも に、寿命の向上を図る。 【構成】 互いに隣接する筒状の煙道1間に介装され撓 み可能な筒部2と筒部2の両側縁に連設され煙道1の開 口3に固着可能なフランジ部4とを有したゴム製の煙道 用継手Jにおいて、ゴムの材質をフッ素ゴムで構成する とともに、外周方向に分割された複数の部分を加熱及び 加圧して接合して構成し、更に、フッ素ゴムに繊維層1 2を介装し、繊維層12の材質を、芳香族ポリアミドで 形成した。
PROBLEM TO BE SOLVED: To enhance manufacturing efficiency of flue joints and enhance service life. SOLUTION: In a rubber-made flue joint (J) having a flexible cylindrical part 2, which is interposed between cylinder-shaped flues 1 adjoining each other and a flange 4 which is continuously provided on both side edges of the cylindrical part 2 and fixable with an opening 3 of a flue 1, the material of the rubber is constituted of fluoro rubber while a plurality of sections divided in the outer peripheral direction are heated, pressurized to be joined, and further a fiber layer 12 is interposed in the fluoro rubber, thereby forming the material of the fiber layer 12 of aromatic polyamide.
