    • In one embodiment, the valve (100) comprises: (a) a housing (101) configured to interengage with a container (401), and having at least one axis (101a) and at least one aperture (105); (b) a first poppet (110) axially movably within said housing (101) between a first closed position and a first open position; (c) a second poppet (120) axially movable within said first poppet (110) between a second closed position and a second open position; (d) a first seal (111) between said first poppet (110) and said housing (101); (e) a second seal (121) between said first poppet (110) and said second poppet (120); (f) a first resilient member (112) disposed within a first space (130) between said housing(101) and said first poppet (110), and having a resilient force sufficient to hold said first poppet (110) in said first closed position such that said first poppet (110) urges said first seal (111) against said housing (101) when a pressure differential axially across said first poppet (110) is below a first point, and to allow said first poppet (110) to move in said first direction to said first open position when said fluid pressure differential exceeds said first point; and (g) a second resilient member (122) disposed within a second space (140) between said first poppet (110) and said second poppet (120), and having a resilient force sufficient to hold said second poppet (120) in said closed position such that that said second poppet (120) urges said second seal (121) against said first poppet (110) when a pressure differential axially across said second poppet (120) is below a second point, and to allow said second poppet (120) to move in a second direction, different from said first direction, to said second open position when said pressure differential exceeds said second point.
    • 在一个实施例中,阀门(100)包括:(a)构造成与容器(401)相互接合并且具有至少一个轴线(101a)和至少一个孔口(105)的壳体(101) (b)在第一关闭位置和第一打开位置之间在所述壳体(101)内可轴向移动的第一提升阀(110) (c)在第二关闭位置和第二打开位置之间在所述第一提升阀(110)内可轴向移动的第二提升阀(120) (d)在所述第一提升阀(110)和所述壳体(101)之间的第一密封件(111); (e)在所述第一提升阀(110)和所述第二提升阀(120)之间的第二密封件(121); (f)设置在所述壳体(101)和所述第一提升阀(110)之间的第一空间(130)内的第一弹性构件(112),并且具有足以将所述第一提升阀(110)保持在所述第一闭合 使得当轴向跨过所述第一提升阀(110)的压差低于第一点时,所述第一提升阀(110)将所述第一密封件(111)推向所述壳体(101),并且允许所述第一提升阀(110) 当所述流体压力差超过所述第一点时,在所述第一方向上移动到所述第一打开位置; 和(g)设置在所述第一提升阀(110)和所述第二提升阀(120)之间的第二空间(140)内的第二弹性构件(122),并且具有足以将所述第二提升阀(120)保持在所述第二提升阀 关闭位置,使得当跨越所述第二提升阀(120)的压力差低于第二点时,所述第二提升阀(120)将所述第二密封件(121)推压抵靠所述第一提升阀(110),并且允许所述第二提升阀 120)当所述压力差超过所述第二点时,沿与所述第一方向不同的第二方向移动到所述第二打开位置。
