J41H/W美标截止阀
详细信息| 询价留言J41H/W美标截止阀一、J41W美标截止阀概述:法兰连接的美标截止阀适用于公称压力PN1.6~16MPa,工作温度-29~550℃的石油、化工、制药、化肥、电力行业等各种工况的管路上,切断或接通管路介质。驱动方式有手动、齿轮传动、电动、气动等.二、J41W美标截止阀结构特点:
①产品的设计制造符合美国国家标准ANS1B16.34,美国BS1873等国外先进标准要求。
②阀体外形为桶形或流线形造型美观。流通形状为直通式。流体阻力小。
③关闭件(闸瓣)与阀座密封面采用锥面密封,关闭力小,耐冲刷,密封可靠。
④阀座可为更换式阀座,可任意组合与关闭密封面材料的配对,以满足工况的要求,延长使用寿命。
⑤大口径、高压力截止阀根据关闭力的需要阀杆的传动方式采用升降杆,并配有滚动轴承式采用撞击式手轮以减轻关闭力。
⑥主体材料、内件材料、填料、紧固件的材料可按用户要求或实际工况条件合理组合。三、J41W美标截止阀设计标准:设计与制造结构长度法兰尺寸对焊连接尺寸压力-温度试验-检验ANSI B16.34 BS1873ANSI B16.10ANSI B16.5ANSI B16.25ANSI B16.34API 598四、J41W美标截止阀试验压力:公称压力PN(Lb)强度试验气密封试验气密封试验MPaLbf/in2MPaLbf/in2MPaLbf/in21503.04302.23150.4-0.760-1003007.711105.781560015.3222011.3163090023.0333017.02445150038.4556028.24080250064.0925547.06790五、J41W美标截止阀主要零部件:
