    • A valve assembly includes a housing having a first chamber, a second chamber, and a valve seat disposed therebetween. A valve head disposed in the housing and is moveable between an open position and a closed position. The valve head defines a bore extending along an axis from the first chamber to the second chamber when the valve head is in the closed position. A valve stem is disposed in the bore and is coupled to the valve head in the bore for moving the valve head between the open and closed positions. The valve assembly allows for selective fluid communication between the first and second chambers to alleviate pressure differences between the first and second chambers. In one embodiment, the valve stem moves in the bore between a sealed position and an unsealed position. In another embodiment, a check valve is disposed in the bore.
    • 阀组件包括具有第一室,第二室和设置在其间的阀座的壳体。 一种阀头,其设置在壳体中并且可在打开位置和关闭位置之间移动。 当阀头处于关闭位置时,阀头限定了沿着轴线从第一室延伸到第二室的孔。 阀杆设置在孔中并且联接到孔中的阀头,用于在打开和关闭位置之间移动阀头。 阀组件允许第一和第二室之间的选择性流体连通以减轻第一和第二室之间的压力差。 在一个实施例中,阀杆在密封位置和未密封位置之间在孔中移动。 在另一个实施例中,止回阀设置在孔中。

    • A combination control valve wherein a seal directed towards the valve exterior is achieved by a double gland which straddles a lantern sleeve with an intermediate vent and is pressed axially between the stem and guide for the main valving member by preloaded elastic elements, said guide being held elastically pressed against the differently inclined surface of a shoulder ring retained by circular sectors fitted into the valve body, a series of labyrinths being interposed between said guide and said main valving member, the pilot valving member being of parabolic profile, a bellows elastic seal element being provided between the first seat and the valve body, the trim including a hollow cylindrical structure which is inserted coaxially into an end cavity in the main relying member, is provided with transverse holes arranged offset from corresponding holes in the cavity of the main valving member, and terminates with a parabolic profile.
    • 一种组合控制阀,其中通过双重密封件实现双向密封,该密封件跨过具有中间通风口的灯套并通过预加载的弹性元件在主阀构件的阀杆和引导件之间轴向地被压紧,所述引导件保持 弹性地压靠在装配到阀体中的圆形扇形区保持的肩环的不同倾斜的表面上,一系列迷宫被插入在所述引导件和所述主阀构件之间,先导阀构件具有抛物线型,波纹管弹性密封元件 设置在第一座椅和阀体之间,该装饰件包括一个中空圆柱形结构,该中空圆柱形结构同轴地插入到主要构件中的端部空腔中,设置有横向孔,该孔与主阀构件的空腔中的相应孔相偏离 ,并以抛物线轮廓终止。

    • A steam governing valve includes a valve body constituting a main valve together with a main valve seat formed on a casing body and having a smaller valve seat inside thereof, a valve rod movable in the valve body in an axial direction of the valve and constituting a smaller valve together with the smaller valve seat, a sleeve arranged in the casing body and guiding the valve body in an axial direction, and a pressure chamber defined by the casing body, the valve body and the sleeve. The pressure chamber communicates with an entrance chamber through a clearance provided on the sliding portions of the sleeve and valve body, and the main valve is opened by lifting the valve rod beyond the fully open position of the smaller valve. The valve body is formed on the cylindrical outer surface thereof with a plurality of axially extending grooves arranged at equal intervals in a circumferential direction. The sleeve is formed with a plurality of steam passages at positions opposite to the axially extending grooves and the pressure chamber communicates with the entrance chamber through the steam passages and the axially extending grooves when the valve body is lifted beyond a predetermined valve opening degree.
    • 蒸汽调节阀包括构成主阀的阀体以及形成在壳体上的主阀座,并且在其内部具有较小的阀座;阀杆,其可沿阀的轴向方向在阀体中移动并构成阀 较小的阀与较小的阀座一起,套筒布置在壳体中并沿轴向引导阀体,以及由壳体,阀体和套筒限定的压力室。 压力室通过设置在套筒和阀体的滑动部分上的间隙与入口室连通,并且通过将阀杆提升到较小阀的完全打开位置来打开主阀。 阀体在其圆柱形外表面上形成有沿圆周方向等间隔布置的多个轴向延伸槽。 套筒在与轴向延伸槽相对的位置处形成有多个蒸汽通道,并且当阀体提升超过预定的阀开度时,压力室通过蒸汽通道和轴向延伸的凹槽与入口室连通。
