供应不锈钢电动闸阀Z941H-16P

闸阀的启闭件是闸板，闸板的运动方向与流体方向相垂直，闸阀只能作全开和全关，不适合作调节和节流。闸板有两个密封面，*常用的楔式闸板阀的两个密封面形成楔形，楔形角随阀门参数而异，通常为5o。楔式闸阀的闸板可以做成一个整体，叫做刚性闸板；也可以做成能产生微量变形的闸板，以*其工艺性，弥补密封面角度在*过程中产生的偏差，这种闸板叫做弹性闸板。 闸阀关闭时，密封面可以只依靠介质压力来密封，即依靠介质压力将闸板的密封面压向另一侧的阀座来*密封面的密封，这就是自密封。大部分闸阀是采用强制密封的，即阀门关闭时，要依靠外力强行将闸板压向阀座，以*密封面的密封性。 闸阀具有以下优点； 1．流体阻力小，密封面受介质的冲刷和侵蚀小。 2．开闭较省力。 3．介质流向不受限制，不扰流、不降低压力。 4．形体简单，结构长度短，制造工艺性好，适用范围广。 公称压力或压力级：PN1.0-16.0MPa、ANSI CLASS 150-300LB、JIS10-20K 公称通径或口径：DN10～1000、NPS 1/2 ～36" 连接方式：法兰、对焊、螺纹等适用温度：-196℃～700℃ 驱动方式：手动、伞齿轮传动、气动、电动、液动、气液联动、电液联动 阀体材料：WCB、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、CF8(304)、CF3(304L)、CF8M(316)、CF3M(316L)、Ti。选用不同的材质，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。:Z41H-10C DN32/Z41H-10C DN40/Z41H-10C DN50/Z41H-10C DN65/ Z41H-10C DN80/Z41H-10C DN100/Z41H-10C DN125/Z41H-10C DN150/Z41H-10C DN200/ Z41H-10C DN250/Z41H-10C DN300/Z41H-10C DN350/Z41H-10C DN400/Z41H-10C DN450/ Z41H-10C DN500/Z41H-10C DN600/Z41H-10C DN700/Z41H-10C DN800/Z41H-10C DN900/ Z41H-10C DN1000/Z41H-16C DN32/Z41H-16C DN40/Z41H-16C DN50/Z41H-16C DN65/ Z41H-16C DN80/Z41H-16C DN100/Z41H-16C DN125/Z41H-16C DN150/Z41H-16C DN200/ Z41H-16C DN250/Z41H-16C DN300/Z41H-16C DN350/Z41H-16C DN400/Z41H-16C DN450/ Z41H-16C DN500/Z41H-16C DN600/Z41H-16C DN700/Z41H-16C DN800/Z41H-16C DN900/ Z941H-16C DN1000/Z41H-25C DN32/Z41H-25C DN40/Z41H-25C DN50/Z41H-25C DN65/ Z41H-25C DN80/Z941H-25C DN100/Z41H-25C DN125/Z41H-25C DN150/Z41H-25C DN200/ Z41H-25C DN250/Z41H-25C DN300/Z41H-25C DN350/Z41H-25C DN400/Z41H-25C DN450/ Z41H-25C DN500/Z41H-25C DN600/Z41H-25C DN700/Z41H-25C DN800/Z41H-25C DN900/ Z41H-25C DN1000/Z41H-40C DN32/Z41H-40C DN40/Z41H-40C DN50/Z41H-40C DN65/ Z41H-40C DN80/Z41H-40C DN100/Z41H-40C DN125/Z41H-40C DN150/Z41H-40C DN200/ Z41H-40C DN250/Z41H-40C DN300/Z41H-40C DN350/Z41H-40C DN400/Z41H-40C DN450/ Z41H-40C DN500/Z41H-40C DN600/Z41H-40C DN700/Z41H-40C DN800/Z41H-40C DN900/ Z41H-40C DN1000/Z41H-64C DN32/Z41H-64C DN40/Z41H-64C DN50/Z41H-64C DN65/ Z41H-64C DN80/Z41H-64C DN100/Z941H-64C DN125/Z41H-64C DN150/Z41H-64C DN200/ Z41H-64C DN250/Z41H-64C DN300/Z41H-64C DN350/Z41H-64C DN400/Z41H-64C DN450/ Z41H-64C DN500/Z41H-64C DN600/Z41H-64C DN700/Z41H-64C DN800/Z41H-64C DN900/ Z41H-64C DN1000/Z41H-100C DN32/Z41H-100C DN40/Z41H-100C DN50/Z41H-100C DN65/ Z41H-100C DN80/Z41H-100C DN100/Z41H-100C DN125/Z41H-100C DN150/Z41H-100C DN200/Z41H-100C DN250/Z41H-100C DN300/Z41H-100C DN350/Z41H-100C DN400/ Z41H-100C DN450/Z941H-100C DN500/Z41H-100C DN600/Z41H-100C DN700/Z41H-100C DN800/Z41H-100C DN900/Z41H-100C DN1000
