rr r r ZSP(N)C型气动活塞切断阀r r r 气动活塞切断阀是由气动活塞执行机构和切断机构组成。按阀芯密封面材料可分为硬密封和软密封;按阀芯结构型式可分为单导向平板式和单导向平衡式。具有结构简单、动作可靠、严密切断、关开快速等特点。适用于无颗粒状、无杂质的气体、液体介质,要求快速严密关闭、快速放空的自动控制系统中。我厂在原有气动角形阀的基础上开发的一种新颖产品。产品广泛应用于石油、化工、冶金、电站、采矿、制药、锅炉、烟草、酒店、建筑、纺织等领域。调节阀适用介质空气、水、蒸汽、各种腐蚀性介质、泥浆、油品等介质。阀门设计均采用装拆简便的结构,当内部零件损坏,只要拆下阀盖螺帽,即可依次取出各个零件,随意调换任何零件,检修非常方便。r r r r r| r r 型号r r | rr r 常温型硬密封r r | rr r 常温型软密封r r | rr r 中温型硬密封r r | rr r 常温型硬密封带手轮r r | rr r 常温型软密封带手轮r r | rr r 中温型硬密封带手轮r r | r
