上海高特自动化仪表厂 调节阀样本 - PAGE 1 - ZMAeq \o(\s\up 9( Q),\s\do 3( X)) 型气动薄膜三通调节阀 ZMAeq \o(\s\up 9( Q),\s\do 3( X)) pneumatic diaphragm three-way regulating valves 产品介绍 General ZMAeq \o(\s\up 5( Q),\s\do 2( X)) 型新系列气动薄膜三通调节阀采用圆筒型薄壁窗口形阀芯结构，不同于柱塞形阀芯的衬套导向。配用多弹簧执行机构，具有结构紧凑、重量轻、体积小、拆装方便等优点。广泛应用于精确控制气体、液体、蒸汽等介质，工艺参数如压力、流量、温度、液位保持在给定值。适合于把一种流体通过三通阀分成二路流出或是把两种流体经三通阀合并成一种流体的场合。 ZMAeq \o(\s\up 5( Q),\s\do 2( X)) new serials pneumatic diaphragm three-way regulating valves have been designed with a barrel thin-wall window type core structure which is different from the sleeve guide of the piston valve cores. It’s used with the multi-spring actuator and features compact structure, low weight, small volume and easy disassembly. It’s widely used for the accurate control of the gaseous and liquid mediums to keep the process parameters including pressure, flow, temperature and fluid level at the given value. The three-way valves are suitable for dividing one fluid into two or collecting two into one.　　本系列产品有三通合流及三通分流两种。公称压力有1.6、4.0、6.4MPa；阀体口径范围DN25~200。适用流体温度由-60℃~+450℃。泄漏量标准为IV级。流量特性有直线、抛物线两种。 This serials product includes three-way collecting type and three-way diving type, covers a range of nominal size 1.6, 4.0, 6.4 MPa, nominal pressure DN25~200. It presents a applicable fluid temperature -60℃~+450 产品特点 Features 流对对阀芯作用方向都处于流开状态，故阀能稳定工作。◇除上阀盖处衬套导向外，阀芯侧面与阀座内表面也有导向作用，导向面积大，工作可靠。◇执行机构采用多弹簧结构，高度减小30%。重量减轻30%。 The fluids flow in the opening direction of the cores with a good working stability. Sleeve guide in the bonnets and the guides at the core side and inside seat surface present a large guide area and reliable operation. With multi-spring actuators, reducing the height by 30% and weight by 30% 主要零件材料 Materials for principal component parts 阀体、阀盖：HT200、ZG230-450、ZG1Cr18Ni9Ti阀芯、阀座：1Cr18Ni9Ti，司太莱合金堆焊波纹膜片：丁晴橡胶夹增强涤纶织物填 料：聚四氟乙烯，柔性石墨膜 盖：A3弹 簧：60SiMn阀杆、推杆：2Cr13、1Cr18Ni9Ti衬 套：2Cr13软密封阀芯：增强聚四氟乙烯垫 片：橡胶石棉板、10、1Cr18Ni9Ti石棉缠绕
