摘要
针对闸阀阀杆填料密封泄漏的问题,提出了正确选择密封填料的材料和改进闸阀填料压盖密封件结构的技术改进措施。实践证明,改造后的闸阀填料密封件不仅结构简单,使用和维修便捷,安全可靠,应用范围广,而且可以在不停运工况下防止闸阀阀杆填料密封渗漏,具有较高的实用价值。
In allusion to the leaking of packing of gate valve,this paper presents technical improvement measures in properly selecting packing material and varying the structure of packing assembly. The technical improvement results show that new packing assembly is satisfactory in structure, reliability and work scope, leaking-free in operation.
