    摘要： A stop valve is provided. The stop valve includes a hollow valve body (10) and a valve core (20). A valve seat (17) is disposed in the valve body (10), and a valve port (171) is disposed on the valve seat (17). At least a portion of the valve core (20) is disposed inside the valve body (10) and can move along an axis of the valve body (10) to block or open the valve port (171). The valve core (20) includes a connecting portion (22) and a guiding portion (23) connected with each other, the guiding portion (23) is disposed at an end of the connecting portion (22) proximal to the valve port (171) and can extend into the valve port (171), an end of the connecting portion (22) proximal to the guiding portion (10) is provided with a third sealing member (233), the third sealing member (233) can abut against the valve seat (17), and at least a part of the guiding portion (10) is pressed against the third sealing member (233).

    摘要： The present invention relates to a Prussian white composite material. The Prussian white composite material includes an inner core and a carbon coating layer that coats at least a portion of an outer surface of the inner core, where the inner core has a general formula of NaxMn1-yMy[Fe(CN)6]z, in the formula, M is selected from at least one of Fe, Co, Ni, Cu and Zn, x is greater than 1.5 and equal to or less than 2, y is greater than 0 and equal to or less than 0.3, and z is greater than 0.8 and equal to or less than 1. The Prussian white composite material of the present invention is free of crystal water (including interstitial water and coordinated water), has complete crystal lattices and good ionic conductivity and thermal stability, and is hardly decomposed at 500°C. A preparation method of the present invention has the advantages of being simple in process, low in cost, short in period, low in energy consumption, suitable for industrial production and the like.

    摘要： Disclosed is an optical fiber cable (100) comprising a central strength member (CSM) (104), a plurality of buffer tubes (106), and a sheath (114). In particular, the plurality of buffer tubes (106) are stranded around the CSM (104) such that each buffer tube encloses optical fibers (116) with one or more protective coating layers (306) having a combined thickness of less than 30 micrometer (µm). Moreover, the plurality of buffer tubes (106) are stranded in at-least two concentric layers around the CSM (104). Further, the sheath (114) surrounds the CSM (104) and the plurality of buffer tubes (106). The optical fiber cable (100) has a fill factor of greater than 7 fibers/millimeter square (f/mm2).
