Gland eye bolts : eyebolts swing aside for ease in repacking the stuffing box 压盖有眼螺栓：有眼螺栓可以从旁边旋起，使得填料函的填料更换更加容易。
Packing : packing contains corrosion inhibitor to avoid stem pitting . stuffing box is deep , assuring long packing life 填料：填料内含防腐剂，避免锈蚀阀杆。深度填料函确保较长的填料使用寿命。
Gland eye bolts : eye bolts are securely fastened to the bonnet yet swing away to permit easy access to the stuffing box 压盖有眼螺栓：有眼螺栓能够安全地紧固阀盖，也可以旋转拆卸，便于方便容易地进入填料函。
Large stuffing box accommodates all packing arrangements , including live - loaded design and lantern ring type for severe services 大型填料函可适应所有填料配置排列，包括适用于严酷应用环境的动负载结构和套环。
This valve uses the packing structure with the ability of self - seal , needs no constant adjustment , features very light open and close and a reliable seal an assisting sealing grease injection structure is set in the packing to have the sealing performance absolutely reliable and get a true null leak , settling the problem for the packing place of universal valves to be easiest leak outward 本阀采用带自密封能力的填料结构，无需经常调节，开、关极为轻便，且密封性可靠，填料函处设有辅助密封油脂注入结构，密封性能绝对可靠，真正达到零泄漏；解决了通用阀门填料处最容易外漏的蔽病。
The ball whets the machine filler letter is a quality that ball whet the machine to seal completely the device primarily , its appearance affects the system directly normal to circulate , this text introduced the ball whets the machine filler letter equips the improvement in front and back of the necessity of the condition , improvement , and good function in empress in improvement 摘要球磨机填料函是球磨机的主要密封装置，其状态的好坏直接影响到系统的正常运行，本文介绍了球磨机填料函装置改进前后的状况、改进的必要性、以及改进后优良的性能。
( 3 ) the transformation for turbo cycling compressor is designed in both differential pressure seal parts at the inlet and outlet and the connecting construction of the positioning key and turbo cycling compressor casing : replace wave pipe of differential pressure seal parts with asbestos jointing and improve its reliability ; jointing connection of the positioning key and turbo cycling compressor casing has been converted into screw thread connection and avoid the dangers from jointing crack ( 3 )从进出口压差密封部件和定位键与外壳间联接结构两方面入手，提出了相应的改造方案：将机组进出口压差的密封部件由波纹管改为石棉填料函，提高了其运行可靠性；将内件周向定位键与外壳间的联接结构由焊接改为螺纹联接，避免了焊接裂纹引起的安全事故。
