Abstract
Description
図1は本発明に係るボールバルブの一実施の形態(実施の形態1)の要部を示す図である。同図において、図13と同一符号は図13を参照して説明した構成要素と同一或いは同等の構成要素を示し、その説明は省略する。
図5に実施の形態2のボールバルブを示す。実施の形態1のボールバルブ1A(図1)では、ボール弁体5を球状としているが、実施の形態2のボールバルブ1(1B)では、ボール弁体5を半球状としている。以下、実施の形態1におけるボール弁体と区別するために、実施の形態1におけるボール弁体をボール弁体5Aとし、実施の形態2におけるボール弁体をボール弁体5Bとする。
図7に実施の形態3のボールバルブを示す。実施の形態2のボールバルブ1C(図5)では、流量特性窓71の壁面(流路の壁面)71a’を上流から下流に向かって狭めたテーパ面としているが、実施の形態3のボールバルブ1(1C)では、流量特性窓71の壁面(71a)をテーパ面とはせずに、リテーナ12の内壁面(流路の壁面)12a’をテーパ面とする。
図9に実施の形態4のボールバルブを示す。実施の形態1のボールバルブ1A(図1)では、ボール弁体5Aの流量特性窓71を上流側としたが、実施の形態4のボールバルブ1(1D)では、ボール弁体5Bの流量特性窓71を下流側とする。このボールバルブ1Dにおいても、流量特性窓71の壁面(流路の壁面)71a’を上流から下流に向かって狭めたテーパ面としている。
図11および図12に、レイノルズ数に相当する係数を(Δp/(ρ1/ρ0))1/2/νとし、この(Δp/(ρ1/ρ0))1/2/νとFR値(レイノルズ数係数)との関係を求めた試験結果を示す。
以上、実施の形態を参照して本発明を説明したが、本発明は上記の実施の形態に限定されるものではない。本発明の構成や詳細には、本発明の技術思想の範囲内で当業者が理解し得る様々な変更をすることができる。
Claims (3)
