Abstract

　低温の流体を高圧の下で制御するに適し、しかも火災安全性を備えた偏心バタフライ弁を提供しようとするものであり、そこで必要とされるシートリングとリテイナーの構造を簡単にして、偏心バタフライ弁の製作を容易にしようとする。 　シートリングの母体として一様な厚みと幅とを持った円環状体を用い、母体の外周部分を表面側から切欠して薄肉の固定部とし、母体の中間部分を上記表面と反対側から固定部の厚み以上の深さに切削して一様な断面の溝を設けた形状に、合成樹脂で一体に作ったものをシートリングとし、溝内にインナーリングを挿入するとともに、溝の開口側にバックアップリングを当接し、バックアップリングにリテイナーを当接してリテイナーにより固定部を弁本体に固定して偏心バタフライ弁とする。
