Abstract
(EN)
The present invention enables a valve body unit to be easily replaced. The present invention is configured such that: a stem 4, a fitting ring member 5, and a valve body unit are moved to a valve seat side 2d by a driving force of a handle 8; a replacement ring 7 is pressed so that the replacement ring 7 moves inside a bonnet 3 while decreasing in diameter, and falls to a flange part 13B in a free state; the stem 4, the fitting ring member 5, the valve body unit 10, and the replacement ring 7 are moved to the reverse side from a valve seat 2d side by the driving force of the handle 8, so that the upper surface 7B of the replacement ring 7 and the lower surface 3C of the bonnet 3 abut each other; and while the flange part 13b abuts the replacement ring 7, only the stem 4 and the fitting ring member 5 are moved to the reverse side from the valve seat 2d side by the driving force of the handle 8, so that the diameter of a connection ring 6 is increased by means of a connection groove 11c of a connection member 11 and the valve body unit 10 falls out of the stem 4.

La présente invention permet de remplacer facilement une unité de corps de soupape. La présente invention est configurée de telle façon que: une tige 4, un élément 5 de bague d'ajustement, et une unité de corps de soupape sont déplacés vers un côté 2d de siège de soupape par une force d'entraînement d'une poignée 8; une bague 7 de remplacement est pressée de telle façon que la bague 7 de remplacement se déplace à l'intérieur d'un capuchon 3 tout en diminuant en diamètre, et tombe jusqu'à une partie 13B de bride dans un état libre; la tige 4, l'élément 5 de bague d'ajustement, l'unité de corps de soupape 10, et la bague 7 de remplacement sont déplacés vers le côté opposé à un côté de siège 2d de soupape par la force d'entraînement de la poignée 8, de telle façon que la surface supérieure 7B de la bague 7 de remplacement et la surface inférieure 3C du capuchon 3 prennent appui l'une sur l'autre; et tandis que la partie 13B de bride prend appui sur la bague 7 de remplacement, seuls la tige 4 et l'élément 5 de bague d'ajustement sont déplacés vers le côté opposé au côté de siège 2d de soupape par la force d'entraînement de la poignée 8, de telle sorte que le diamètre d'une bague 6 de liaison est accru au moyen d'une rainure 11c de liaison d'un élément 11 de liaison et que l'unité de corps de soupape 10 tombe hors de la tige 4.

容易に弁体ユニットを交換可能な技術を提供する。 ハンドル8による駆動力により、ステム4、嵌め輪部材5、および弁体ユニットを弁座2d側へ移動させて、交換リング7を押すことにより、交換リング7が縮径しながらボンネット3内を移動して、フランジ部13Bへ自由状態となって落下し、ハンドル8による駆動力により、ステム4、嵌め輪部材5、弁体ユニット10、および交換リング7を弁座2d側とは反対側へ移動させて、交換リング7の上面7Bとボンネット3の下面3Cとを当接させ、かつ、フランジ部13Bを交換リング7に当接させた状態で、ハンドル8の駆動力により、ステム4および嵌め輪部材5のみを弁座2d側とは反対側へ移動させて、連結部材11の連結溝11cにより連結リング6を拡径させ、弁体ユニット10がステム4から外れるように構成されている。
