力士乐截止阀*,REXROTH截止阀简单介绍: 截止阀又称截门阀,属于强制密封式阀门,所以在阀门关闭时,必须向阀瓣施加压力,以强制密封面不泄漏。当介质由阀瓣下方进入阀门时,操作力所需要克服的阻力,是阀杆和填料的摩擦力与由介质的压力所产生的推力,关阀门的力比开阀门的力大,所以阀杆的直径要大,否则会发生阀杆顶弯的故障。按连接方式分为三种:法兰连接、丝扣连接、焊接连接。从自密封的阀门出现后,截止阀的介质流向就改由阀瓣上方进入阀腔,这时在介质压力作用下,关阀门的力小,而开阀门的力大,阀杆的直径可以相应地减少。同时,在介质作用下,这种形式的阀门也较严密。我国阀门“三化给"曾规定,截止阀的流向,一律采用自上而下。截止阀开启时,阀瓣的开启高度,为公称直径的25%~30%时.流量已达到zui大,表示阀门已达全开位置。所以截止阀的全开位置,应由阀瓣的行程来决定。接下来由颖哲工业自动化叶帆为大家介绍一下REXROTH截止阀的优点以及其他特性 力士乐截止阀*,REXROTH截止阀的优点: 1、双重的密封设计(波纹管+填料)若波纹管失效,阀杆填料也会避免; 2、外泄漏,并符合密封标准; 3、没有流体损失,降低能源损失,提高工厂设备安全; 4、使用寿命长,减少维修次数,降低经营成本; 5、坚固耐用的波纹管密封设计,保证阀杆的零泄漏,提供无需维护的条件。 6、波纹管密封截止阀采用波纹管密封的设计,*消除了普通阀门阀杆填料密封老化快易泄露的缺点,不但提高了使用能源效率,增加生产设备安全性,减少了维修费用及频繁的维修保养,还提供了清洁安全的工作环境。 ,我公司从事液压行业多年,在市场上拥有良好的口碑,本公司拥有数千万库存,在产品价格及供货周期上有较强的优势,zui大限度的满足用户的需求。有着*的技术人员、优秀的销售人员,为纺织、制造、食品、包装机械、工矿企业、电厂等企业提供优质产品及良好的技术服务。产品包括液压元件、气动元件、工控产品、电磁阀阀、泵、传感器、压力开关、空气处理设备、污水处理设备等等欧美进口自动化设备。 ,REXROTH截止阀常用型号选型参考: R901224218DA6VA2A5X/200FSM、R901184165DA6VA2A5X/200FSV R901224223DA6VA2A5X/350FSM、R901184169DA6VA2A5X/350FSV R901224230DA6VA2B5X/50FSM、R901184170DA6VA2B5X/50FSV R901224226DA6VA2B5X/100FSM、R901184669DA6VA2B5X/100FSV R901224246DA6VA2B5X/200FSM、R901184173DA6VA2B5X/200FSV R901224228DA6VA2B5X/350FSM、R901184176DA6VA2B5X/350FSV R901224234DA6VP2A5X/50FSM、R901184151DA6VP2A5X/50FSV R901224232DA6VP2A5X/100FSM、R901184158DA6VP2A5X/100FSV R901224233DA6VP2A5X/200FSM、R901184160DA6VP2A5X/200FSV R901224247DA6VP2A5X/350FSM、R901184161DA6VP2A5X/350FSV R901224244DA6VP2B5X/50FSM、R901184177DA6VP2B5X/50FSV R901224235DA6VP2B5X/100FSM、R901184179DA6VP2B5X/100FSV R901224238DA6VP2B5X/200FSM、R901184183DA6VP2B5X/200FSV R901224242DA6VP2B5X/350FSM、R901184186DA6VP2B5X/350FSV R901224225DA6VA2A5X/50FSM、R901184162DA6VA2A5X/50FSV R901224217DA6VA2A5X/100FSM、R901184163DA6VA2A5X/100FSV R901224218DA6VA2A5X/200FSM、R901050795PVV54-1X/183-069RA15UUMC R901045673PVV4-1X/098RA15LMC、R901044270PVV2-1X/040RA15UVB R901042655PVV54-1X/154-082RA15UUMC、R901042651PVV41-1X/082-040RA15UUMC R901042169PVV21-1X/045-040LA15UUMB、R901040968PVV1-1X/040RA15UVB R901040503PVV1-1X/036RJ15DVB、R901040430ABUPG-PVV1-46U-1X/100L-4-A0K/SABB R901037970PVV1-1X/018RA15RMB、R901036232PVV51-1X/193-027RA15UUMC R901034701PVV54-1X/193-122RJ15DDMC、R901033123ABUPG-PVV21-45-18U-1X/100L-4-A0/S R901031937PVV2-1X/055RA15DVB、R901031658PVV21-1X/068-046RA15UUMB R901029208ABAPG-PVV2-068U/100L-4-A0/SE、R901028783PVV2-1X/045LA15UMB R901027161ZUBEHOERAB41-20A1X/B35-100/0-PVV2/M、R901026966PVV54-1X/154-122RB15UUMC R901025366ABUPG-PVV1-18U-1X/80-4-O1HAN10ESS/S、R901024714PVV51-1X/162-046RA15DDMC R901024704PVV4-1X/082RJ15UMC、R901023158PVV21-1X/045-040RA15UUMB R901020330PVV41-1X/122-027RA15DDMC、R901020329PVV52-1X/193-045RB15LLMC R901018208PVV54-1X/139-122RJ15UUMC、R901014437PVV4-1X/082LA15UMC R901012238PVV4-1X/122RA15DVC、R901012150PVV41-1X/082-018RB15UUMC R901009013PVV21-1X/040-027RA15UUMB、R901006812SY2DFEE-2X/100-PVV/01006744+00940446 R901006811SY2DFEE-2X/071-PVV/01006745+00946959、R901004734PVV21-1X/055-036RA15UUMB R901002834PVV41-1X/069-018RJ15UUMC、R901002823PVV52-1X/162-068RA15UUMC R901001457SY2DFEE-2X/071-PVV/00782146+00940260、R900978703PVV4-1X/082RA15DVC R900977523ABAPG-PVV/017D493A
