一、进口角式波纹管截止阀概述

进口角式波纹管截止阀，Angle bellows globe valve，也叫角形波纹管截止阀，直角式波纹管截止阀，角式结构截止阀，是指采用直角型的结构形式的波纹管密封截止阀，适用于公称压力PN1．6～16MPa，工作温度-29～350℃的易燃、易爆、剧毒、毒性流体、高温导热油、液氨等介质。广泛应用于：石油化工、化纤纺织、塑料造纸、电力钢铁、印染橡胶、天然气等其它气体系统。

Angle bellows globe valve, also known as angle bellows globe valve, right angle bellows globe valve, angle structure globe valve, refers to a bellows sealed globe valve with a right angle structure, suitable for flammable, explosive, highly toxic, toxic fluids, high-temperature thermal oil, liquid ammonia, and other media with a nominal pressure of PN1.6-16MPa and a working temperature of -29-350 ℃. Widely used in other gas systems such as petrochemicals, chemical fiber textiles, plastic papermaking, power steel, printing and dyeing rubber, natural gas, etc.
