Description
Claims (1)
- 空気に燃料ガスを混合し、混合気をファンを介してバーナに供給する予混合装置であって、燃料ガスを供給する流量調節弁を介設したガス供給路の下流端がファンの上流側の空気供給路に接続され、空気供給路の通気抵抗を大小に切換える空気抵抗切換手段と、流量調節弁よりも下流側のガス供給路の部分の通気抵抗を大小に切換えるガス抵抗切換手段とを備えるものにおいて、
空気抵抗切換手段は、空気供給路内に回動自在に設けられたバタフライ弁で構成され、
バタフライ弁の下流側の空気供給路の部分に、バタフライ弁を配置した空気供給路の部分と同心で、且つ、この部分よりも断面積が小さなベンチュリ部と、ベンチュリ部から下流側に向けて断面積が次第に増加する拡径部とが設けられ、
ガス抵抗切換手段の下流側のガス供給路の部分に、ベンチュリ部を全周に亘り囲うガス室と、ガス室から拡径部のベンチュリ部寄りの基端部に燃料ガスを吸引するガス吸引部とが設けられ、ガス吸引部は、拡径部の周壁を基端側の一部でベンチュリ部の周壁から切り離して径方向外方に張り出させることにより、周方向に等間隔で複数形成され、拡径部の基端部の全周に亘り燃料ガスが吸引されるようにすると共に、
バタフライ弁は、空気供給路の長手方向に沿う開き姿勢と、空気供給路の長手方向に直交する閉じ姿勢との2つの姿勢にのみ切換えられ、
更に、バタフライ弁の回転軸線に直交する断面形状はひし形であって、且つ、バタフライ弁を閉じ姿勢に回動したときに、空気供給路の周面とバタフライ弁の外周との間に環状の隙間が形成されるようにし、閉じ姿勢で空気供給路の上流側を向くバタフライ弁の面の傾斜により、空気が前記隙間を介してベンチュリ部の周壁面に沿って流れるように案内されることを特徴とする予混合装置。
