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 (2)
- 流路を形成する弁本体と、前記弁本体内に弁軸を中心に回動可能に配設されたボール弁体とを備え、前記ボール弁体は、前記弁軸と直交する方向に形成された貫通流路を有し、前記貫通流路は、前記ボール弁体の外周面に開口する流量特性窓と、前記ボール弁体に形成されて一端が前記流量特性窓と接続し他端が前記弁本体の流路と接続する空洞とを有し、前記弁軸を中心として前記ボール弁体を回動させることによって前記弁本体内の流路を流れる流体に対する流量特性窓の開き量を調節するボールバルブにおいて、
前記流量特性窓は、
前記ボール弁体の外周面から前記空洞にかけて徐々に狭められ、前記空洞との接続部分において前記貫通流路の最狭径部を形成し、前記流体が前記流量特性窓から前記貫通流路に流入するときに前記最狭径部の直後に最縮流部が形成され、
前記空洞は、
前記一端の側に前記最狭径部から流路を拡大させる拡大部を含み、
前記貫通流路は、
前記流量特性窓が、前記ボール弁体の外周面から前記空洞にかけて徐々に狭められ、かつ、前記空洞が前記拡大部を有することによって、前記最縮流部の流れが受ける前記最狭径部の壁面からの摩擦の影響を軽減して、前記最縮流部の流れの様相が非乱流状態と乱流状態とで変わらないようにする
ことを特徴とするボールバルブ。 - 請求項1に記載されたボールバルブにおいて、
前記流量特性窓の前記外周面の開口から前記最狭径部にかけての壁面は、流体の流れる方向に対して最大で10°の傾斜を有する
ことを特徴とするボールバルブ。
