JY41W-16T|JY41W-25T|JY41W-40T氧气截止阀产品说明：概述：氧气阀作为冶金工业中输送氧气管路上的启闭装置，较其它通用阀门相比有许多特别严格的要求。因为氧气属易燃易爆危险品，所以必需防泄漏，防静电，防火花，以避免发生事故。在结构上，设计为：阀瓣启闭时阀杆只升降而不转动，有效地降低了密封副磨损、填料磨损和上密封磨损；侧法兰上装有接地螺钉，避免产生静电火花；阀杆外露部分用有机玻璃密闭封盖，用以防尘防油。技术参数阀体材质1Cr18Ni9Ti公称压力PN(MPa)2.5公称通径DN(mm)15-400性能描述特点具有密封性能好，操作轻便灵活，安全可靠，使用寿命长等优点。一、压力试验型号公称压力壳体试验压力PsMPa气密封试验适用温度℃适用介质水气JY41W-25/40P2.53.82.52.5常温氧气二、主要零件材料及性能零件名称阀体/阀盖阀瓣阀杆阀杆螺母填料垫片材料CF8F304F304QAL9-4PTFEPTFE铜合金F304F304QAL9-4PTFEPTFE三、规格主要尺寸1.6Mpa尺寸DN1520253240506580100125150200250300350400Lmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm1201401601602002002402402803203605606007008009002.5MpaLmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm1201401601602002002402402803203605606007008009004.0MpaLmm130150160180200230290310350400480600650750850950Hmm200243253280312321325355415460510700975111512501380Wmm120140160160200200240240280320360560600700800900)
