摘要 |
<p>An improved live load packing system (34) for sealing an operating valve member (16) in a fluid valve (10). A packing follower (36) includes a base (38) and a guide sleeve (40) adapted for slidable engagement on the operating valve member (16). A series of Belleville disk springs (46) slidably engage the guide sleeve (40) and maintain concentric mounting during loading of V-type TFE packing members (22) to ensure uniform concentric spring loading and to prevent undesired side loading. <IMAGE></p> |
