    • An expansion joint for connecting first and second fluid-carrying pipes comprising first and second annular couplings which are operably affixable to respective ones of the pipes. In a preferred embodiment the couplings include cylindrical bores of substantially the same diameter disposed relative to one another to form a passage for providing flow communication between the pipes. An annular bellows extends between the couplings for accommodating relative axial movement and angular misalignment between the pipes and is disposed radially outward of the passage to capture any fluid leaking between the interfacing surfaces of the couplings. A second cylindrical bore of a first one of the couplings engages an outer spherical surface of the second coupling to allow the second coupling to pivot in a manner which accommodates angular misalignment between the pipes. Means are provided for limiting the pivoting of the second coupling and for preventing the first coupling from rotating about a centerline of the joint, thereby avoiding unacceptable bending and torsional loading of the bellows. The expansion joint further includes means for limiting the axial compression and axial extension of the bellows.
    • 一种用于连接第一和第二流体输送管的膨胀接头,包括第一和第二环形联接器,其可操作地固定在相应的管道中。 在优选实施例中,联接器包括相对于彼此设置的基本上相同直径的圆柱形孔,以形成用于在管之间提供流动连通的通道。 环形波纹管在耦合器之间延伸,用于容纳管道之间的相对轴向运动和角度偏移,并且设置在通道的径向外侧,以捕获在联接器的接口表面之间泄漏的任何流体。 联接器中的第一联接器的第二圆柱形孔接合第二联接器的外球面,以允许第二联接器以容纳管之间的角度偏移的方式枢转。 提供了用于限制第二联接器的枢转并且用于防止第一联接件围绕接头的中心线旋转的装置,从而避免波纹管的不可接受的弯曲和扭转负载。 膨胀接头还包括用于限制波纹管的轴向压缩和轴向延伸的装置。

    • An adjustable loop clamp assembly provides improved retention of electrical cables, tubes or hoses. The clamp assembly comprises a flexible strap with first and second ends. A base, having an elevated platform, a lower platform, a midsection, and two side supports, receives a second end of the strap in an aperture of the midsection. The first strap end is securably affixed to the elevated platform of the base. Support holes in the side supports receive pin portions of a locking cam, the locking cam further comprising a handle portion and a cam portion. A mount bolt is receivable in alignable apertures of the lower platform and the handle portion. The pin portions of the locking cam are pivotably engaged into the mount holes of the side supports, allowing rotation of the locking cam into a position that engages the strap with the cam portion, locking the strap against the base structure, simultaneously contacting the handle portion against the lower platform, further aligning the mount holes in the handle portion and the lower platform so that when a mount bolt is passed through those holes and secured, the locking cam is prevented from disengagement.
    • 可调节的回路夹具组件可改善电缆,管或软管的保持力。 夹具组件包括具有第一端和第二端的柔性带。 具有升高的平台,下部平台,中部和两个侧面支撑件的基座在中部的孔中容纳带的第二端。 第一条带端部牢固地固定到基座的升高的平台上。 侧支撑件中的支撑孔接收锁定凸轮的销部分,锁定凸轮还包括手柄部分和凸轮部分。 安装螺栓可接收在下平台和手柄部分的对准的孔中。 锁定凸轮的销部分可枢转地接合到侧支撑件的安装孔中,允许锁定凸轮旋转到与凸轮部分接合带的位置,将带锁定在基座结构上,同时接触手柄部分 抵靠下平台,进一步对准手柄部分和下平台中的安装孔,使得当安装螺栓穿过这些孔并被固定时,防止锁定凸轮脱离。

    • A coupling assembly for fluid carrying tubes in a gas turbine engine include first and second fittings fixedly joined to respective ones of the tubes. The first and second fittings include respective first and second mating flanges which are joined together by a clamping band which is adjustable therearound. The first and second flanges include oppositely facing first and second flat faces, with the first flange having a counterbore extending inwardly from the first face, and the second flange having a pilot tube extending outwardly therefrom for being inserted into the counterbore. An annular seal is disposed between the first and second fittings for providing a leak-proof coupling upon clamping together of the two fittings by the clamping band.
    • 用于燃气涡轮发动机中用于流体输送管的联接组件包括固定地连接到各个管的第一和第二配件。 第一和第二配件包括各自的第一和第二配合凸缘,其通过可绕其周围的夹紧带连接在一起。 第一和第二凸缘包括相对面对的第一和第二平面,其中第一凸缘具有从第一面向内延伸的沉孔,并且第二凸缘具有从其向外延伸的先导管,以插入沉孔中。 环形密封件设置在第一和第二配件之间,用于通过夹紧带将两个配件夹紧在一起来提供防漏接头。
