    • Fluid valve apparatus having enclosed seals are disclosed. An example fluid valve includes a movable flow control member positioned between an inlet and an outlet of a fluid flow passageway of the fluid valve. A retainer is removably coupled to the flow control member such that the retainer and the flow control member define a sealing cavity when the retainer is coupled to the flow control member. A seal is positioned within the sealing cavity to define a sealing surface of the flow control member. The seal has an inner core composed of a first material, where the core is substantially encased with a sheath composed of a second material different than the first material. The retainer clamps the seal to the flow control member.
    • 公开了具有封闭密封件的流体阀装置。 示例性流体阀包括位于流体阀的流体流动通道的入口和出口之间的可移动流量控制构件。 保持器可移除地联接到流量控制构件,使得当保持器联接到流量控制构件时,保持器和流量控制构件限定了密封腔。 密封件位于密封腔内以限定流量控制构件的密封表面。 密封件具有由第一材料构成的内芯,其中芯基本上包围由不同于第一材料的第二材料构成的护套。 保持器将密封件夹紧到流量控制构件。

    • A plug valve including a valve body having an inlet port, an outlet port and a central chamber extending between the inlet port and the outlet port. The valve also includes an inlet seal segment within the central chamber and includes a bore extending therethrough and aligned with the inlet port. An outlet seal segment is disposed within the central chamber having a bore extending therethrough and aligned with the outlet port. A plug member is disposed in the central chamber and is moveable between an open position, to facilitate fluid flow through the plug valve, and a closed position, to block fluid flow through the plug valve. First and second side segments are disposed between and interlocked to the inlet and outlet seal segments to encircle the plug member. The side segments are tensioned to preload the seal segments against the plug member to prevent the flow of fluid between the seal segments and the plug member.
    • 一种旋塞阀,包括具有入口端口,出口和在入口和出口之间延伸的中心室的阀体。 该阀还包括在中央室内的入口密封段,并且包括延伸穿过其并与入口对准的孔。 出口密封段设置在中心室内,其具有延伸穿过其中并与出口端对准的孔。 插塞构件设置在中央室中并且可以在打开位置之间移动,以便于流过插塞阀的流体和关闭位置,以阻止流过该插塞阀的流体。 第一和第二侧段设置在入口和出口密封段之间并与之互锁,以包围塞子构件。 侧段被张紧以将密封段预先装载到塞子构件上,以防止密封段和塞构件之间的流体流动。

    • A cylindrical plug valve (10) including a body (1) with an internal channel (2) and a cylindrical housing (5), a plug (10) with a cylindrical outer surface closely fitted in the cylindrical housing (5) and provided with an internal duct (11), and packing means between the cylindrical surface of the plug (10) and the cylindrical surface of the housing (5). Said packing means include a ring-shaped seal (18) fitted into a groove (19) in one of the cylindrical surfaces. The closed ring formed by the seal around the axis (6) of the surface is such that when the cut-off member (10) is placed in the closed position by rotating it through 90 DEG , one of the internal ports (8, 9) of the channel is separated from the internal duct (11) by the seal (18) which forms a continuous barrier therebetween at the cylindrical surfaces of the housing and the plug.
