    • The invention relates to a method and an apparatus for the surface blasting, especially for the ultrasonic shot peening, of gas turbine blades in the area of their blade roots. The apparatus encompasses at least one vibrator, especially at least one ultrasonic sonotrode (12), comprising an oscillating surface (13), whereby the or each vibrator is oriented in such a manner so that the oscillating surface (13) of the or each vibrator extends essentially in the horizontal direction, whereby a processing chamber (14), for receiving the or each blade root (15) to be processed, adjoins the or each oscillating surface (13). According to the invention, the processing chamber (14) is embodied in such a manner so that the or each gas turbine blade (11) is orientable in such a manner for the surface blasting so that during the blasting at least one profiled support surface, which is to be processed, of the or each blade root (15) extends at least temporarily essentially parallel to the oscillating surface (13) of the or each vibrator, especially the or each ultrasonic sonotrode.
    • 本发明涉及一种用于在其叶片根部区域中的燃气轮机叶片的表面喷砂,特别是用于超声喷丸处理的方法和装置。 该装置包括至少一个振动器,特别是包括振荡表面(13)的至少一个超声波超声波发生器(12),由此该振动器或每个振动器以这样的方式定向,使得振动器或振动器的振动表面(13) 基本上在水平方向上延伸,由此用于接收待处理的叶片根部或每个叶根部(15)的处理室(14)与该振动表面(13)相邻。 根据本发明,处理室(14)以这样的方式实施,使得该燃气轮机叶片(11)可以以这种方式定向用于表面喷砂,使得在喷射至少一个成型支承表面期间, 每个叶片根部(15)的至少一个或多个叶片根部(15)至少临时延伸地基本平行于振动器的振动表面(13),特别是每个超声波超声波发生器。

    • A valve includes a chamber having an inlet, an outlet, and an annular recess. A movable element is disposed in the chamber to control the flow of fluids between the inlet and the outlet. A stem is secured to a movable element and extends exteriorly through the annular recess. A seal and a fastener are disposed around the stem. The fastener is in displaceable engagement and disengagement with the stem and has recesses formed in each of its exterior side surfaces. A plurality of mounting pads are positioned around the annular recess. The mounting pads are elevated to provide separation between the fastener recesses and a peripheral surface. A method of constructing the mechanical valve includes tightening the fastener around the stem by engaging a recess with an axial tool.
    • 阀包括具有入口,出口和环形凹部的腔室。 可移动元件设置在腔室中以控制入口和出口之间的流体流动。 杆被固定到可移动元件并且在外部延伸穿过环形凹部。 密封件和紧固件设置在阀杆周围。 紧固件与杆头可移动地接合和分离,并且在其每个外侧表面中形成有凹部。 多个安装垫定位在环形凹部周围。 安装垫被提升以提供紧固件凹部与周边表面之间的间隔。 构造机械阀的方法包括通过将凹部与轴向工具接合来将紧固件紧固在杆上。
