    • In a mechanical seal for the rotary shaft of a rotary machine wherein the pressure difference between the internal and external liquids acting on the mechanical seal changes from positive to negative, and vice versa, a ring and a seat ring are formed with mating seal faces which coact to seal between the internal and exterior liquid present externally and internally, respectively, of the retainer; the seat ring is securely and liquid-tightly mounted on the rotary shaft for rotation therewith in a casing; the ring is fitted over a retainer axially movably, but nonrotationally and is normally pressed against the seat ring under the force of a bias spring which provides the sealing force for maintaining the seal between the seal faces when the external liquid pressure exceeds the internal liquid pressure, but the pressure difference is relatively small; the retainer in turn is mounted in the casing nonrotationally but axially movably due to the difference in pressure between the internal and external liquids, whereby regardless of the difference in pressure between the internal and external liquids, the seal may be maintained securely.
    • 在用于旋转机械的旋转轴的机械密封件中,其中作用在机械密封件上的内部和外部液体之间的压力差从正向变化到负,反之亦然,环和座环形成有配合密封面, 共同密封在保持器的外部和内部分别存在的内部和外部液体之间; 所述座圈牢固且液密地安装在所述旋转轴上,以便在壳体中旋转; 环被安装在轴向可移动的保持器上,但是非旋转地并且通常在偏置弹簧的作用下被压靠在座环上,当偏压弹簧的作用力提供密封力时,当外部液体压力超过内部液体压力时,该密封力保持在密封面之间 ,但压差相对较小; 保持器依次由于内部和外部液体之间的压力差异而非旋转地安装在壳体中,但是可轴向移动,由此不管内部和外部液体之间的压力差如何,可以可靠地保持密封。

    • A fluid-tight closure apparatus for providing a fluid-tight seal between the inner peripheral surface of the cylindrical bore in an enclosure receiving therein a high-pressure fluid and the outer peripheral surface of an end closure wall held in the cylindrical bore. The apparatus has a pressurizing ring fitted around the outer peripheral surface at the inner end portion of the end closure wall for a small axial displacement. The pressurizing ring is adapted to derive the required sealing pressure from the internal fluid pressure in the enclosure. The apparatus further has a seal ring disposed between the pressurizing ring and the inner peripheral surface of the cylindrical bore and/or between the pressurizing ring and the end closure wall, and a bolt screwed through the end wall member into the pressurizing ring for imparing an initial sealing surface pressure to sealing areas, through the axial displacement of the pressurizing ring toward the end closure wall.
    • 一种流体密封闭合装置,用于在容纳高压流体的外壳中的圆柱形孔的内周表面和保持在圆柱形孔中的封端壁的外周表面之间提供流体密封的密封。 该装置具有围绕端盖的内端部的外周表面安装的加压环,用于小的轴向位移。 加压环适于从外壳中的内部流体压力导出所需的密封压力。 该装置还具有设置在加压环和圆柱形孔的内周表面之间和/或加压环和封闭壁之间的密封环,以及螺栓穿过端壁构件进入加压环的螺栓,用于刺穿 初始密封表面压力到密封区域,通过加压环朝向端盖的轴向位移。

    • A mechanical seal for use with shafts of rotary machines is of unitary construction for ease in handling. It can be attached to, and detached from, the sealing portion of the shaft accurately and readily. The attachment and detachment of the seal are expedited by the combination of a protuberance or protuberances of a shaft sleeve which is mounted on the shaft and carries a rotating seal element, and circumferential and axial grooves formed on the inner surface of a retainer which holds a stationary seal element.
    • 用于旋转机械轴的机械密封件具有整体结构,易于处理。 它可以准确而容易地附着到轴的密封部分上并与其分离。 通过组合安装在轴上并承载旋转密封元件的轴套的突起或凸起的组合,以及形成在保持器的内表面上的周向和轴向槽,可以加速密封的附接和拆卸, 固定密封元件。
