Title (EN) VALVE DEVICE AND STORAGE WATER HEATER
(FR) DISPOSITIF DE TYPE VANNE ET CHAUFFE-EAU À ACCUMULATION
(JA) 弁装置及び貯湯式給湯機
Abstract:
(EN) This valve device (1) comprises; a housing (2); an inlet port (4); an outlet port (5); a first chamber (9) which is formed inside the housing (2) and is in fluid communication with the inlet port (4); a second chamber (10) which is formed inside the housing (2) and is in fluid communication with the outlet port (5); and an escape valve mechanism (11) which discharges the fluid in the first chamber (9) to the interior of the second chamber (10) when the pressure in the first chamber (9) exceeds a first pressure. At least a portion of the escape valve mechanism (11) is located inside the second chamber (10). This valve device (1) has an air passage (21) which allows the air outside the housing (2) to flow into the second chamber (10) without passing through the outlet port (5) when the pressure in the second chamber (10) is equal to atmospheric pressure.
(FR) La présente invention concerne un dispositif de type vanne (1) comprenant : un logement (2) ; un orifice d'entrée (4) ; un orifice de sortie (5) ; une première chambre (9) qui est formée à l'intérieur du logement (2) et qui est en communication fluidique avec l'orifice d'entrée (4) ; une seconde chambre (10) qui est formée à l'intérieur du logement (2) et est en communication fluidique avec l'orifice de sortie (5) ; et un mécanisme de soupape d'écoulement (11) qui évacue le fluide dans la première chambre (9) vers l'intérieur de la seconde chambre (10) lorsque la pression dans la première chambre (9) dépasse une première pression. Au moins une partie du mécanisme de soupape d'écoulement (11) est située à l'intérieur de la seconde chambre (10). Ce dispositif de type vanne (1) comporte un passage d'air (21) qui permet à l'air à l'extérieur du logement (2) de s'écouler dans la seconde chambre (10) sans passer par l'orifice de sortie (5) lorsque la pression dans la seconde chambre (10) est égale à la pression atmosphérique.
(JA) 弁装置(1)は、ハウジング(2)と、入口ポート(4)と、出口ポート(5)と、ハウジング(2)の内部に形成され、入口ポート(4)に流体連通する第一室(9)と、ハウジング(2)の内部に形成され、出口ポート(5)に流体連通する第二室(10)と、第一室(9)内の圧力が第一圧力を超えると第一室(9)内の流体を第二室(10)内へ排出させる逃がし弁機構(11)と、を備える。逃がし弁機構(11)の少なくとも一部が第二室(10)の内部に位置する。第二室(10)内の圧力が大気圧に等しいときに、ハウジング(2)の外部の大気を、出口ポート(5)を通らずに第二室(10)内に流入させることが可能な通気路(21)を有する。
