摘要： An adapter union is disclosed which is especially useful for installation by butt welding on containers for fluids to permit a conduit of smaller internal diameter to be removably attached thereto, and also for certain other specialized uses described herein. The adapter union includes an improved butt weld adapter member. When desired, the adapter member may be installed on containers for fluids by butt welding to thereby permit a conduit of smaller diameter to be attached directly thereto. The disclosure further relates to containers for fluids having the adapter union and/or the adapter member installed thereon. When the adapter union is installed properly, the resultant structure provides for permanency of the installation when desired, and also allows future changes and modifications to be made easily and without damaging the adapter union and/or conduits or other cooperating apparatus attached thereto.
摘要翻译：公开了一种适配器联接件，其特别适用于通过对流体的容器进行对接焊接来安装，以允许较小内径的管道可移除地附接到其上，以及用于本文所述的某些其它特殊用途。适配器接头包括改进的对接焊接适配器构件。当需要时，适配器构件可以通过对接焊接安装在用于流体的容器上，从而允许较小直径的导管直接附接到其上。本公开还涉及用于具有安装在其上的适配器联接件和/或适配器构件的流体的容器。当适配器接头安装正确时，所得到的结构在需要时提供安装的永久性，并且还允许容易地进行未来的改变和修改，而不会损坏连接到其上的适配器接头和/或导管或其他协作设备。

摘要： A flange union is disclosed which is provided with inner and outer annular metal-to-metal seals and an optional resilient seal and/or insert. In one embodiment, the two metal-to-metal seals are formed simultaneously, and in another embodiment they are formed sequentially thereby allowing the second to be used as a back-up seal. The configuration of the metal sealing surfaces is such that an annular metal-to-metal line seal of minimum surface area is formed closely adjacent the internal diameter of the bore, and an annular metal-to-metal line seal is formed, or is capable of being formed, outward therefrom. This sealing structure results in markedly less stress and strain on the flange bolts to achieve and maintain the desired sealing pressure. Male-female sealing surfaces mate adjacent the internal diameter of the bore, and the flange union is self aligning in that area. The flange union will seal effectively with the flange members being either in or out of alignment. Inserts are used to extend the life of the flange union and to render it useful for a number of other purposes.
摘要翻译：公开了一种法兰联接件，其设置有内外环形金属对金属密封件和可选的弹性密封件和/或插入件。在一个实施例中，两个金属对金属密封件同时形成，并且在另一个实施例中，它们依次形成，从而允许第二个密封件用作后备密封件。金属密封面的构造使得最小表面积的环形金属对金属线密封形成为紧邻孔的内径，并且形成环形金属对金属线密封件，或者能够从其形成。这种密封结构导致凸缘螺栓上的应力和应变明显较小，以实现和保持所需的密封压力。公 - 母密封表面邻近孔的内径配合，并且法兰接头在该区域中自对准。法兰联接件将有效地密封凸缘部件进入或不对准。插入件用于延长法兰接头的使用寿命，并使其适用于许多其他目的。

摘要： An access union is disclosed which is especially useful for installation on containers for fluids to permit access thereto. The invention is also concerned with containers for fluids having the access union of the invention installed thereon. When installed on containers for fluids, the access union of the invention provides for permanency of the installation when desired, and also allows future changes and modifications to be made easily and without damaging the access union and/or an access conduit or other cooperating apparatus attached thereto.

摘要： A flange union is disclosed which is provided with opposed recessed female seats carried by the terminal inner ends of the flange members. A replacable sealing ring having an annular convex sealing surface is positioned between the annular cooperating sealing surfaces of the female seats. The configuration of the sealing surfaces is such that an annular metal-to-metal line seal of minimum surface area is formed closely adjacent the internal diameter of the bore. This results in the need for markedly less stress and strain on the flange bolts to achieve and maintain the sealing pressure. The flange union will seal effectively with the flange members being either in or out of alignment.

摘要： A valve comprising a body having a straight-through flow passage, a valve head moveable at an acute angle with the downstream end of the passage into and out of the passage, and a valve seat extending about the passage for cooperation with the valve head to adjust the valve over a range from the wide-open to the closed condition, the valve seat approaching the axis of the passage no more closely than does the wall of the narrowest portion of the passage upstream or downstream of the seat, whereby in the wide-open condition, the valve head is removed from the passage, the axis of the passage remains a straight line, and the cross-sectional area of the passage at the position of the seat is no less than it is at the narrowest portion of the passage upstream or downstream of the seat.
