放大字体  缩小字体 发布日期:2020-08-01  浏览次数:16
■1.概述
                        随着科学技术的不断进步和产品的不断更新,工业阀门的需求量已有显著的提高,蝶阀的使用已从常温低压发展到高温高压,以及耐磨、耐腐蚀等领域。由于蝶阀具有体积小、重量轻、操作灵活、安装方便、流通能力大等优点,在食品、医药、石油、化工、环保、高层建筑、给排水及冶金、矿山、轻纺、能源等领域中已大量的取代了闸阀、截止阀等其它阀门。 本厂研制的主要产品有:硬、软密封蝶阀、通风蝶阀、伸缩器。引进消化国外先进工艺技术,在设计、制造、检验等过程中严格按照ISO9001国际质量体系的要求控制。本产品还可根据顾客的配置设定,可选用气动、电动、蜗轮、手动四种型式提供配置。
                        ■2.特点及用途
                        蝶阀该产品结构紧凑,体积小,重量轻,操作灵活,密封性能好,流体阻力小,使用寿命长,安装方便,不有耐高温等优点。同时采用三偏心结构,其连接形式为对夹式,也可采用法兰连接式、焊接式。公称压力:PN0.1Mpa~6.4Mpa,公称通径:DN32~2500mm,工作温度-80~550oC,材质:铸钢、不锈钢、合金钢。适用于蒸气、油品、硝酸、氧化性介质以及排水等管道设备。
