摘要： An improved live load packing system for sealing an operating valve member in a fluid valve. A packing follower includes a base and a guide sleeve with a non-metallic inner liner adapted for slidable engagement on the operating valve member. A series of Belleville disk springs slidably engage the guide sleeve outer diameter and maintain concentric mounting during loading of V-type TFE packing members to ensure uniform concentric spring loading and to prevent undesired side loading. A window permits viewing the position of the guide sleeve and inner liner during packing loading adjustment so that optimum loading can be attained and maintained when the viewer notes the top edge of the guide sleeve and inner liner is flush with the top surface of the packing flange.

摘要： A fluid control valve in which the usual metal stem guide bushings have been eliminated. A fluid control valve includes a valve bonnet and a packing nut threadably engaging the valve bonnet. A valve stem passes through the valve bonnet and the packing nut in a clearance fit so that there is no engagement therebetween. Two packing sets of V-type PTFE packing are included with each set having a middle virgin PTFE sealing ring, a carbon or glass filled PTFE male packing ring on one side and a carbon or glass filled PTFE female ring on the other side. Belleville disk springs are provided intermediate the packing nut and the two packing sets, for supplying live loading to the packing. In an unloaded condition, initially the packing sets both are in a clearance fit with the valve stem. Threadably inserting the packing nut into the valve bonnet until there are no visible threads at the top of the bonnet ensures a sufficient loading to seal the valve stem, seal the inside diameter of the bonnet, and to provide a sufficient stem guidance, interference fit with the valve stem to enable the usual upper and lower metal guide bushings to be eliminated.
摘要翻译：流体控制阀，其中通常的金属杆引导衬套已经被去除。流体控制阀包括阀帽和与阀帽螺纹接合的填料螺母。阀杆通过阀帽和密封螺母以间隙配合，使得它们之间没有接合。每组包括两个包装的V型PTFE填料，每组包括一个中间原始的PTFE密封圈，一面是碳或玻璃填充的PTFE阳性填料环，另一面是碳或玻璃填充的PTFE阴环。 Belleville碟形弹簧设置在包装螺母和两个包装组件的中间，用于为包装提供活动载荷。在卸载状态下，最初的包装组件都与阀杆间隙配合。将密封螺母螺纹地插入阀盖，直到阀盖顶部没有可见的螺纹，确保有足够的负载来密封阀杆，密封阀芯的内径，并提供足够的阀杆引导，过盈配合阀杆能够消除通常的上下金属导套。
