防火聚四氟乙烯软管组件的设计

聚四氟乙烯软管组件具有耐温等级高、弯曲半径小、柔性好等优异性能,弥补了橡胶软管组件耐温等级低、金属软管组件刚性大的不足,在各行各业得到了广泛应用。本文通过对聚四氟乙烯软管、金属接头、防火性及扣压模具进行优化设计,提升了软管组件耐压、耐高低温、防静电、防火等性能,能够满足不同系统软管组件的使用需求。;PTFE hose assemblies, with many excellent performances such as high-temperature resistance, small bending radius, good flexibility, are widely used in industries. They compensate for the disadvantages like low temperature resistance of rubber hoses and strong rigidity of metal hose assemblies. This paper makes research on optimization of the PTFE hoses, metal fittings, fire proof property and crimping moulds. Based on these optimal designs, PTFE hose assemblies obtain better performances of high and low temperature resistance, pressure-resistance, antistatic and fire proof property, so that the assemblies can meet the needs of different systems
