调节阀用常温密封填料结构分析及改进

Structure Analysis and Improvement of Control Valve Sealing Packing at Normal Temperature

介绍了调节阀密封填料在阀门运行中出现阀杆处介质外漏,而对用户及阀门制造厂产生一定的能源损失、经济损失及声誉产生的不良影响,鉴于此种情况而对阀用密封填料的结构进行改进,改进后的密封填料,有效的解决了以上问题。

This paper introduced the medium leaked from the stem sealing packing when the control valve acted,which caused energy losses,economic losses and bad reputation for users and manufactories.In order to solve the problem,it designed and improved the structure of the sealing packing.Beneficial effect was obtained after improving.
