Development of Spiral Gland of Packing Assembly for Gate Valve and its Application
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.
