Abstract
(EN)
A steam valve having a first inclined surface (61b), which is formed at the distal end portion (61A) of a valve rod (61) and in which the outer diameter of the valve rod (61) increases from the distal end toward the base end of the valve rod (61), and a second inclined surface (76d), which is formed on the inside of a portion of a master valve (64) that is positioned on the base-end side of the valve rod (61) and which inclines with the same inclination angle as the first inclined surface (61b). In a state in which a slave valve (62) and the master valve (64) are closed the first inclined surface (61b) and the second inclined surface (76d) are separated from each other, and when the slave valve (62) and the master valve (64) are in a fully open state the first inclined surface (61b) and the second inclined surface (76d) abut each other.
(FR)
L'invention concerne une soupape de vapeur dotée d'une première surface inclinée (61b), qui est formée sur la partie d'extrémité distale (61A) d'une tige de soupape (61) et dans laquelle le diamètre externe de la tige de soupape (61) augmente depuis l'extrémité distale vers l'extrémité de base de la tige de soupape (61), et une seconde surface inclinée (76d), qui est formée sur l'intérieur d'une partie d'une soupape principale (64) qui est positionnée sur le côté d'extrémité de base de la tige de soupape (61) et qui s'incline avec le même angle d'inclinaison que la première surface inclinée (61b). Dans un état où une soupape asservie (62) et la soupape principale (64) sont fermées, la première surface inclinée (61b) et la seconde surface inclinée (76d) sont séparées l'une de l'autre, et lorsque la soupape asservie (62) et la soupape principale (64) sont dans un état complètement ouvert, la première surface inclinée (61b) et la seconde surface inclinée (76d) viennent en butée l'une contre l'autre.
(JA)
弁棒(61)の先端部(61A)に形成され、弁棒(61)の先端側から基端側に向かうにつれて弁棒(61)の外径を拡径させる第1の傾斜面(61b)と、親弁(64)のうち、弁棒(61)の基端側に位置する部分の内側に形成され、第1の傾斜面(61b)と同じ傾斜角度で傾斜する第2の傾斜面(76d)と、を有し、子弁(62)及び親弁(64)が閉じた状態において、第1の傾斜面(61b)と第2の傾斜面(76d)とが離れた状態となり、子弁(62)及び親弁(64)が全開状態のときに、第1の傾斜面(61b)と第2の傾斜面(76d)とが当接される。
