(JA) ストレーナ装置
Abstract
(EN) This strainer device 100 comprises: a casing 10 in which a drain inflow path 11 and a drain outflow path 12 are formed; a screen 20 which is provided in the casing 10 and captures foreign substances in the drain flowing from the inflow path 11 to the outflow path 12; and a valve mechanism 30which is provided to the casing 10 and which has a discharge hole 33 through which the drain having passed through the screen 20 is discharged, and a valve body 31 that opens/closes the discharge hole 33, wherein the valve mechanism 30 has a spring 34, which biases the valve body 31 in the valve opening direction, and is configured so that when the pressure of the drain having passed through the screen 20 is lowered to a predetermined value, the valve body 31 opens the discharge hole 33 by means of the biasing force of the spring 34.
(FR) Ce dispositif de crépine 100 comprend : un boîtier 10 dans lequel sont formés un chemin d'entrée de drain 11 et un chemin de sortie de drain 12; un tamis qui est disposé dans le boîtier et capture des substances étrangères dans le drain s'écoulant du chemin d'écoulement d'entrée au chemin d'écoulement sortant ; et un mécanisme de soupape 30 qui est disposé sur le boîtier 10 et qui a un trou de décharge 33 à travers lequel le drain ayant traversé le tamis 20 est déchargé, et un corps de soupape 31 qui ouvre/ferme le trou de décharge 33, le mécanisme de soupape 30 ayant un ressort 34, qui sollicite le corps de soupape 31 dans la direction d'ouverture de la soupape, et est configuré de telle sorte que lorsque la pression du drain ayant traversé le tamis 20 est abaissée à une valeur prédéterminée, le corps de soupape 31 ouvre le trou de décharge 33 au moyen de la force de sollicitation du ressort 34.
(JA) ストレーナ装置100は、ドレンの流入路11および流出路12が形成されたケーシング10と、ケーシング10内に設けられ、流入路11から流出路12に流れるドレン中の異物を捕捉するスクリーン20と、ケーシング10に設けられ、スクリーン20を通過したドレンが排出される排出孔33、排出孔33を開閉する弁体31を有する弁機構30とを備え、弁機構30は、弁体31を開弁方向に付勢するバネ34を有し、スクリーン20を通過したドレンの圧力が所定値まで低下すると、バネ34の付勢力によって弁体31が排出孔33を開放するように構成されている。
