摘要： The present application pertains to a braided dual-sided compression packing seal, methods for producing and using such a seal, and apparatuses suitable for producing such a seal. The braided dual-sided compression packing seal is made up of two or more different materials that are braided together in such a way that, in cross-section, the compression packing seal has an asymmetrical configuration relative to a first axis that is substantially perpendicular to the longitudinal axis and is substantially perpendicular to a side of the compression packing seal. Accordingly, when viewed in a cross-sectional plane, the compression packing seal may expose substantially only a first material along a first side of the seal, and substantially only a second material along a second side of the seal.

摘要： A seal device for a turbine includes: a plurality of thin plates arranged along an outer peripheral surface of the rotor, each of the thin plates including a root portion disposed on an outer side in a radial direction of the rotor and supported on a stationary part of the turbine and a tip portion disposed on an inner side in the radial direction of the rotor and having a tip surface facing the outer peripheral surface of the rotor. Each of the thin plates is configured such that a width direction of the thin plate is parallel to an axial direction of the rotor at a side of the root portion, and the tip portion of each of the thin plates is configured such that an end on a side of the high-pressure space is positioned downstream of another end on a side of the low-pressure side.

摘要： A shaft sealing mechanism (11) that partitions an annular space (14) that is formed between a fixed part (12) and a rotating shaft (13) into a high-pressure-side region and a low-pressure-side region, that obstructs the flow of a fluid (G), and that is provided with: a plurality of annularly laminated thin-plate seal pieces (22) that are fixed to an annular seal housing (21) that is provided to the fixed part and are in sliding contact with the rotating shaft; and an annular low-pressure-side plate (26) that is sandwiched and held such that a low-pressure-side gap (δL) is formed between the seal housing and a low-pressure-side side edge part (22d) of the thin-plate seal pieces. The thin-plate seal pieces have pressure-conduction holes (31) that are formed further to the inside in the radial direction of the rotating shaft than an inner-circumferential-side tip part (26a) of the low-pressure-side plate.

摘要： Apparatus are provided for a device with improved heat resistance. The device includes a body and an encasing layer disposed substantially entirely around the body. The encasing layer includes a fabric layer and a coating. The fabric layer has a first end and a second end coupled together about the perimeter of the body to enclose the body, and the fabric layer includes an exterior surface. The coating is disposed on the exterior surface of the fabric layer, and the coating forms a barrier for the fabric layer.

摘要： A gland packing having required characteristics is obtained by finding relationships between required characteristics and the value of the limiting oxygen index, and adequately defining the level of the required characteristics. The gland packing is configured by twisting or braiding a single or plurality of yarns that are formed by twisting fibers having a limiting oxygen index (LOI) of 21 to 30, preferably 22 to 26. The fibers contain fibers in which a flat ratio is defined as 1.1 to 4, the flat ratio being a value which is obtained by dividing the maximum value of an interval between two parallel straight lines in a state where a section of each of the fibers is interposed between the straight lines, by the minimum value. The fibers contain fibers in each of which a sectional shape has one or more recesses having a depth of 0.4 μm or more.

摘要： A backup ring for a face seal in a roller cone bit is configured to resist wear from drilling fluids present adjacent exposed faces of the backup ring. Portions are removed from an exposed end face in a variety of shapes while the hardness of the material is increased. The removal of material offsets an increase in force that would be transmitted through the backup ring on face seal assembly due to flexing. A spring can optionally be included in the removed material location. Another way is to increase the edge density of all or part of the exposed edges while leaving the interior portions unaffected by using electron beam radiation to increase the crosslink density or by other techniques that allow a unitary structure with a more durable edge region.
摘要翻译：用于辊锥形钻头中的面密封件的支撑环被配置为抵抗与备用环的暴露面相邻的钻井液的磨损。部件从各种形状的露出端面移除，同时材料的硬度增加。材料的去除抵消了由于弯曲而将通过表面密封组件上的支撑环传递的力的增加。可以可选地在去除的材料位置中包括弹簧。另一种方法是增加所有或部分暴露边缘的边缘密度，同时通过使用电子束辐射不影响内部部分以增加交联密度，或通过允许具有更持久的边缘区域的整体结构的其它技术来增加边缘密度。

摘要： A yarn mainly configured by expanded graphite is improved to be so highly flexible that the expanded graphite does not protrude in a usual bending process, in order to prevent partial missing of the expanded graphite from occurring when the yarn is twisted or braided to produce a gland packing. A yarn 1 for a gland packing is formed by filling the interior of a tubular member 3 configured by knitting or braiding an inconel wire 2 having a diameter of 0.1 mm, with fibrous expanded graphite 4 having a section in which an aspect ratio is set to 1 to 5, the aspect ratio being a value obtained by dividing the width w by the thickness t.
