Title
(EN) VALVE CORE AND NITROGEN SPRING
(FR) OBUS DE VALVE ET RESSORT À AZOTE
(ZH) 气门芯及氮气弹簧
Abstract
(EN)
A valve core and a nitrogen spring, wherein the valve core comprises a core body (1), a through hole cavity is formed in the core body (1), and a stepped hole (12) is formed in the through hole cavity; a core rod (3), which is kept in the through hole cavity, the core rod (3) comprises a sealing portion (31) and a limiting portion (32), wherein the sealing portion (31) is arranged on the outer end of the core body (1), the limiting portion (32) is arranged in the interior of the core body (1), the diameter of the stepped hole (12) is greater than that of the core rod (3), the core rod (3) is arranged to move axially in the stepped hole (12); a sealing pad (2), which is provided with a through hole, the sealing pad (2) is arranged between the end portion of the core body (1) and the sealing portion (31); a gas passage is formed between the stepped hole (12) and the core rod (3); the core rod (3) is arranged to be in a first position when the limiting portion (32) is in contact with the stepped hole (12), so that the gas can pass through the gas passage; the core rod (3) is further arranged to be in a second position when the sealing portion (31) is pressed against the stepped hole (12) through the sealing pad (2), and the through hole cavity is sealed by the sealing pad (2).
(FR)
La présente invention concerne un obus de valve et un ressort à azote, l'obus de valve comprenant un corps d'obus (1), une cavité de trou traversant étant formée dans le corps d'obus (1), et un trou étagé (12) étant formé dans la cavité de trou traversant ; une tige centrale (3), qui est maintenue dans la cavité de trou traversant, la tige centrale (3) comprend une partie d'étanchéité (31) et une partie de limitation (32), la partie d'étanchéité (31) étant disposée sur l'extrémité externe du corps d'obus (1), la partie de limitation (32) étant disposée à l'intérieur du corps d'obus (1), le diamètre du trou étagé (12) étant supérieur à celui de la tige centrale (3), la tige centrale (3) étant agencée pour se déplacer axialement dans le trou étagé (12) ; un tampon d'étanchéité (2), qui est pourvu d'un trou traversant, le tampon d'étanchéité (2) est disposé entre la partie extrémité du corps d'obus (1) et la partie d'étanchéité (31) ; un passage de gaz est formé entre le trou étagé (12) et la tige centrale (3) ; la tige centrale (3) est agencée pour être dans une première position lorsque la partie de limitation (32) est en contact avec le trou étagé (12), de telle sorte que le gaz peut passer à travers le passage de gaz ; la tige centrale (3) est en outre agencée pour être dans une seconde position lorsque la partie d'étanchéité (31) est pressée contre le trou étagé (12) à travers le tampon d'étanchéité (2), et la cavité de trou traversant est rendue étanche par le tampon d'étanchéité (2).
(ZH)
一种气门芯及氮气弹簧,气门芯包括芯体(1),芯体(1)中有通孔内腔,通孔内腔内设置有台阶孔(12);芯杆(3),芯杆(3)容纳在通孔内腔中,芯杆(3)包括密封部(31)和限位部(32),密封部(31)设置在芯体(1)外端,限位部(32)位于芯体(1)的内部,台阶孔(12)的直径大于芯杆(3)的直径,芯杆(3)设置为在台阶孔(12)内轴向活动;密封垫(2),密封垫(2)上设有通孔,密封垫(2)设置在芯体(1)的端部与密封部(31)之间;台阶孔(12)与芯杆(3)之间形成的气体通道;芯杆(3)设置为当限位部(32)与台阶孔(12)接触时处于第一位置,使气体能够从该气体通道通过,芯杆(3)还设置为当密封部(31)通过密封垫(2)与台阶孔(12)抵压时处于第二位置,并通过密封垫(2)对通孔内腔密封。
