    • 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,出口端口和在入口端口和出口端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 valve head blank consisting of a briquette of water-atomized high-temperature-resistant metal powder, commonly called ''''superalloy powder'''' (FIGS. 1 to 5 inclusive) is compressed by the upper punch of a briquetting press in the cavity of a die containing a core rod to form a socket in the head, which is then sintered in a sintering furnace in a protective atmosphere at about 2,000* F. Meanwhile, a valve stem of ordinary steel has been cold-headed or machined at its upper end to form a slightly flared reduced-diameter nose thereon. This valve stem is placed in the die cavity of a press with its flared nose projecting upward into the die cavity. A trumpet-shaped lubricant sleeve of nonferrous metal, such as copper, is then placed in the die cavity, followed by the reheated sintered valve head with its socket telescoping with the flared nose of the valve stem. The upper punch of the press is then caused to compress and thin the valve head while at the same time to elongate and interlock the neck thereof with the flared nose of the valve stem by an extrusion action as the metal lubricant sleeve facilitates the deformation of the respective parts. Alternatively (FIGS. 6 to 9 inclusive), gas-atomized superalloy powder is molded into a valve head blank consisting of a preform in a mold also containing a core pin, this assembly being sintered in a sintering furnace as before. A flared-nose stem is again placed in the die cavity, followed by the lubricant metal sleeve and hot sintered preform, whereupon the hot-forming, extruding and elongating operation is carried out as before.
