    Abstract: 本发明公开一种高性能压缩机阀组装置,包括阀板,阀片和阀片限位件,阀片设置在阀板和阀片限位件之间,阀板上开设有至少一个阀孔和缓冲孔,阀片覆盖在阀孔上,缓冲孔内设有缓冲弹性件,阀片的前部设有与缓冲孔相适应的定位凸块,定位凸块伸入缓冲孔中与缓冲弹性件抵接,阀片的端部卡紧在阀片限位件和阀板之间,阀片上涂覆有抗磨耐腐蚀薄膜。与现有技术相比,本发明设计合理,通过阀片限位件将阀片压紧在阀板上进行密封,阀片上设置的球形滑块在限位滑槽中滑动,防止其在往复运动时发生侧倾,阀片上设置的定位凸块和阀板上的缓冲弹性件配合使用,减小冲击力,降低振动噪声;阀片表面涂覆抗磨耐腐蚀薄膜,具有耐高温、耐磨损、抗化学腐蚀等优点。

    Abstract: 本发明公开了一种可输送高浓度加砂压裂液的压裂泵减振泵阀装置。该装置包括凡尔胶皮、阀杆、减振橡胶、阀盘、非金属圆盘、金属压板、锁紧螺母、矩形橡胶圈和阀座。阀盘、减振橡胶、非金属圆盘等零件通过锁紧螺母与阀杆固定在一起,组成阀盘系统。阀杆的下导向杆上安装有四个矩形橡胶圈,并将其穿过阀座的导向支架上,使阀盘系统平稳的坐落在阀座上。当泵阀即将关闭时,非金属圆盘梯形斜槽将过滤一定范围的固体颗粒,降低了阀盘、颗粒和阀座之间的磨料磨损;当泵阀关闭时,凡尔胶皮和减振橡胶将降低阀盘对阀座的冲击作用。该装置阀盘系统质量较轻,有利于提高压裂泵的冲次,同时改善了泵阀的抗冲击和抗磨损性,具有较高的实用价值。

    Abstract: A valve device includes a body that defines a passage through which a fluid flows, a shaft that is movably supported with respect to the body and defines an axis, a valve element that is fixed to the shaft to open and close the passage; and a cylindrical bearing bush that movably supports the shaft with respect to the body, in which the bearing bush includes a mixed region in which a metal core material and expanded graphite are mixed with each other, and a first expanded graphite region made of only the expanded graphite such that the metal core material is not exposed in an inner circumferential side region in contact with an outer circumferential surface of the shaft.
