Ｑ４５F夹套保温球阀也称夹套球阀，是在球阀的基础上焊装金属夹套，用于注入蒸汽或其它保温、保冷介质，确保阀内介质能够正常工作。夹套保温球阀结构紧凑、外型美观、密封性能好。也能实现管道中介质流向的切换。也能使相互垂直的两个通道连通或关闭。夹套保温球阀造型美观，结构紧凑合理，它不仅可实现介质流向的切换，也可使三个通道相互连通，同时也可关闭任一通道，使另外两个通道连通，灵活控制管路中介质的合流或分流。可分别适用于水、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。型号Ｑ４５类型(通道位置)三通式材质碳钢连接形式法兰结构形式浮动球球阀公称通径５０－１０００（mm）适用介质水。油等压力环境常压工作温度常温标准国标零部件及配件球体用途锁闭T型国标连接尺寸和外形PN1.6MPa型号公称通径DN(mm)尺寸(mm)LL2DD1D2bfZ-dHWQ45F-16C(P)(R)15150729565451424-1495130201608010575551424-14110130251809011585651424-1812014032200100135100781624-1814418040220110145110851634-18152220502401201601251001634-23182240652601301801451201634-18193270802801401951601352038-182173501003201602151801552038-182455001253801902452101852238-182826001504402202802402102438-23319100020055026033529526526312-23380130025067031040535532030312-25460170030072037046041037530312-255202100T型美标连接尺寸和外形150Lb公称通径DN尺寸(mm)(in)(mm)LDD1D2bfZ-φdHLO1/2151408960.535101.64-φ15551303/420165987043111.64-φ155513012516510879.551121.64-φ157014011/4322201177964131.64-φ157518011/24025012798.573151.64-φ159022021/250260152120.592161.64-φ19104260265320178139.5105181.64-φ19153350380320190152.5127191.64-φ191874004100370229190.5157241.68-φ192065005125510254216186241.68-φ222526006150510279241.5216261.68-φ2224410008200580373298.5270291.68-φ22283130010250670406362324311.612-φ25345160012300720483432381321.612-φ254202100)
