SMCITV系列电气比例阀ITV3050-314CL使用注意事项SMC电气比例阀ITV3050系列正品保障;原装正品SMC电气比例阀ITV3050系列到货上海电气比例阀ITV1000·2000·3000系列;SMC电气比例阀ITV3050系列正品保障SMC电气比例阀是一种新型的液压控制装置。
在普通压力阀、流量阀和方向阀上,用比例电磁铁替代原有的控制部分,按输入的电气信号连续地、按比例地对油流的压力、流量或方向进行远距离控制。
一般具有压力补偿性能,输出压力和流量可以不受负载变化的影响。
该比例阀是一种按输入的电信号连续地、按比例地控制液压系统的液流方向、流量和压力的阀类。
普通阀只能通过预调的方式对液流的压力、流量进行定值控制。
但是当设备机构在工作过程中要求对液压系统的压力、流量参数进行调节或连续控制,例如,要求工作台在工作进给时按慢、快、慢连续变化的速度实现进给,或按一定精度模拟某个控制曲线实现旅力控制,普通液压阀则实现不了。
比例阀的输出流量与气体性质,有效通气面积,阀门前后两端的气压压差有关,通过比例阀的气体绝大部分为氧气和空气(N2,O2N_2,O_2N2?,O2?),均为双原子气体分子,气体动力学性质基本相同,在模型中可以不用考虑气体自身性质的影响。
动作原理输入信号增大时,1供气电磁阀变为ON,2排气电磁阀变为OFF。
因此,供给压力通过1供气电磁阀作用在3先导室。
并且,3先导室的压力上升,作用在4膜片上面。
由此结果,与4膜片连动的5供气阀打开,一部分供给压力成为输出压力。
此输出压力,通过7压力传感器反馈到8控制回路。
在此,会进行压力调节,直至输出压力与输入信号成比例,因此,可以稳定地得到与输入信号成比例的输出压力。
高速响应型托架同包出厂。
无负载时的压力响应,响应时间约为0.1sec。
取决于使用环境,非保证值。
输入信号0%时,控制排气电磁阀使输出压力为零。
这种情况下可能会产生噪音,但并非异常。
SMC 先导式精密减压阀介绍
用压缩空气的作用力代替调压弹簧力以改变出口压力的阀,称为先导式减压阀。
它调压时操作轻便,流量特性好,稳压精度高,压力特性也好,适用于通径较大的减压阀。
先导式减压阀调压用的压缩空气,一般是由小型直动式减压阀供给的。
若将这个小型直动式减压阀与主阀合成一体,则称为内部先导式减压阀。
若将它与主阀分离,则称为外部先导式减压阀,它可实现远距离控制。
SMC IR系列先导式精密减压阀结构原理
下图是SMC IR系列先导式精密减压阀结构原理图。
顺时针旋转设定手轮1,调压弹簧3被压缩,推动挡板7,关闭喷嘴6,输入气压力通过固定节流孔2流入膜片B的上腔,气压力推动膜片C,使主阀芯4开启,则有压力输出。
此输出压力一方面作用在膜片C的下腔,与膜片B的上腔气压力相平衡;另一方面,通过OUT侧通路,进入膜片A下腔,与设定弹簧力相平衡,以维持出口压力不变。
当出口压力增大,膜片A上移,喷嘴与挡板开启,膜片B上腔压力下降,则膜片B、C组件上移,常泄式排气阀芯5瞬时开启,出口压力下降,又维持出口压力不变。
喷嘴挡板机构和常泄式排气阀的溢流作用对压力调节是很敏感的,故能实现精密稳压。
SMC IR系列先导式精密减压阀技术参数
SMC IR系列先导式精密减压阀使用注意
1)普通型减压阀,出口压力不要超过进口压力的85%;精密减压阀,出口要压力不要超过进口压力的90%。
输出压力不得超过设定压力的最大值。
2)连接配管要充分吹洗。
3)空气的流动方向按箭头方向安装,不得装反。
4)使用塑料材质的减压阀,应避免阳光直射。
阀门的三个基本参数阀门是工业生产中常见的一种用来控制流体的装置。
它的三个基本参数是:阀门口径、阀门类型和阀门材质。
本文将分别介绍这三个基本参数的作用和特点。
一、阀门口径阀门口径是指阀门内部流体通道的直径,通常使用毫米(mm)作为单位进行表示。
阀门口径的大小决定了阀门的流量和阻力。
一般来说,口径越大,阀门的流量就越大,但同时也会带来更大的压力损失。
因此,在选择阀门时需要根据具体的工况条件和流量需求来确定合适的口径。
阀门口径的选择应考虑以下几个方面:1. 流体性质:不同的流体具有不同的流动特性,有些流体对管道的阻力较大,因此需要选择较大口径的阀门来减小阻力损失。
2. 流量要求:根据流量要求选择合适的阀门口径,以保证流体的正常运行和工艺的顺利进行。
3. 管道条件:管道尺寸和阀门口径应相匹配,以确保流体的顺畅流动。
二、阀门类型阀门的类型多种多样,根据不同的工况和使用要求,可以选择不同类型的阀门。
常见的阀门类型包括截止阀、球阀、蝶阀、调节阀等。
1. 截止阀:截止阀主要用于切断或接通管道中的流体,具有良好的密封性能和较大的阻力。
常用于需要严格控制流体流量和压力的场合。
2. 球阀:球阀具有结构简单、操作方便、密封性能好等特点。
它的流体通道是一个球体,通过旋转球体来实现流体的开启和关闭。
3. 蝶阀:蝶阀的结构简单、体积小、重量轻。
它的流体通道是一个圆盘,通过旋转圆盘来控制流体的流量和压力。
4. 调节阀:调节阀主要用于调节流体的流量和压力,可以根据需要调整阀门的开度来控制流体的通畅程度。
不同类型的阀门适用于不同的工况和需求,选择合适的阀门类型可以提高生产效率和流体控制的精度。
三、阀门材质阀门的材质是指阀门主要构件的材料,它直接影响到阀门的强度、耐腐蚀性和使用寿命。
常见的阀门材质包括铸铁、不锈钢、黄铜等。
1. 铸铁:铸铁阀门具有较高的强度和耐腐蚀性,适用于一般工况下的流体控制。
2. 不锈钢:不锈钢阀门具有良好的耐腐蚀性和高温性能,适用于化工、石油、食品等工业领域。

1.概述SMC系列阀门电动装置是Limitorque阀门电动装置的主体,其技术是Limitorque技术的精华和集中体现。
由SMC系列可派生出若干形式的电动装置产品。
由于被驱动控制的阀门形式不同,Limitorque电动装置亦分为两种基本形式:第一种用于控制多回转阀门,如闸阀、截止阀、隔膜阀等。
第二种用于控制部分回转阀门,如球阀、蝶阀、旋塞阀等。
在部分回转电动装置产品中通常又细分为组合式(亦称叠加式)和独立式(亦称整体式)两种结构型式。
组合式是一级多回转产品和二级减速器的组合,独立式则是将整个减速系统设置在同一个主箱体中。
实践证明,独立式部分回转电动装置是一个经济型产品,它虽然体积相对小,但组合式的很多优势它并不具备。
所以在控制性能要求较高的工况条件多首选组合式产品。
Limitorque电动装置属于高档次的产品,因而其部分回转产品多为组合式。
实际上,在多回转电动装置结构上亦有组合式的情况,最典型的是SMC系列与BA系列减速器的组合,这些会在下面详细介绍。
1.1SNC系列多回转阀门电动装置:SMC系列做为一种多回转产品,它所控制的阀门工作时阀瓣做直线运动,如最常见的楔式闸阀,平板闸阀、截止阀等等。
多回转电动装置的工作特点是:输出轴(亦称驱动空心轴)工作时做多圈回转并驱动阀杆螺母或阀杆旋转,进而带动阀瓣做上下往返运动完成阀门的启闭。
(设阀杆轴线垂至于地面)SMC系列电动装置的输出轴为上下贯通,以保证明杆阀门的阀杆通过或进入。
电动装置单行程旋转的圈数取决于阀门的口径和阀杆丝杆部分的参数。
多回转阀门可由电动装置完成行程控制关闭或转矩控制关闭,也可将两种控制形式配合使用。
SMC系列产品具有可靠的行程、转矩控制性能。
从Limitorque的直译“ 转矩限制”,我们可见输出转矩值是一个产品的重要参数。
根据输出转矩的不同又形成了产品的不同结构型式及尺寸,即不同的机座号。
SMC系列多回转电动装置共有9个机座号,它们是SMC-04~SMC~5。
SMC减压阀工作原理和型号介绍
一.SMC减压阀工作原理
1.顺时针调节手轮,调压弹簧被压缩,推动膜片组件下移,通过阀杆,打开阀芯,则入口气压力
经阀芯节流降压,压力输出;
2.出口压力气体经反馈管进入膜片下腔,在膜片产生一个向上的推力。
当此推力与调压弹簧力平
衡时,出口压力便稳定一定在值。
二.SMC减压阀特点
1.体积小,重量轻。
2.比传统的精密减压阀IR200输出流量大。
3. 比传统的精密减压阀IR200溢流流量大。
4.压力设定精确。
5.调节螺钉的齿间距由传统的0.75mm改为0.5mm。
6. 安装方便,可用托架独立安装或与现在的模块式过滤组合元件AF及AFM直接安装。
7.标准型也带面板安装。
8.先导排气口与主排气口分开。
9. 可在洁净房使用(特注产品)。

SMC气控阀相关知识SMC气控阀从原理上分为三大类:1)直动式SMC气控阀:原理:通电时,电磁线圈产生电磁力把关闭件从阀座上提起,阀门打开;断电时,电磁力消失,弹簧把关闭件压在阀座上,阀门关闭。
特点:在真空、负压、零压时能正常工作,但通径一般不超过25mm。
2)分布直动式SMC气控阀:原理:它是一种直动和先导式相结合的原理,当入口与出口没有压差时,通电后,电磁力直接把先导小阀和主阀关闭件依次向上提起,阀门打开。
当入口与出口达到启动压差时,通电后,电磁力先导小阀,主阀下腔压力上升,上腔压力下降,从而利用压差把主阀向上推开;断电时,先导阀利用弹簧力或介质压力推动关闭件,向下移动,使阀门关闭。
特点:在零压差或真空、高压时亦能可动作,但功率较大,要求必须水平安装。
3)先导式SMC气控阀:原理:通电时,电磁力把先导孔打开,上腔室压力迅速下降,在关闭件周围形成上低下高的压差,流体压力推动关闭件向上移动,阀门打开;断电时,弹簧力把先导孔关闭,入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差,流体压力推动关闭件向下移动,关闭阀门。
特点:流体压力范围上限较高,可任意安装(需定制)但必须满足流体压差条件。
SMC气控阀是用电磁控制的工业设备,是用来控制流体的自动化基础元件,属于执行器,而气动SMC气控阀是其中的一种,是通过控制阀体的移动来档住或漏出不同的排油的孔,而进油孔是常开的,液压油就会进入不同的排油管,然后通过气动SMC气控阀的油的压力来推动油缸的活塞,这样通过控制气动SMC气控阀的电磁铁的电流就控制了整个SMC气控阀的机械运动。
SMC气控阀一般阀芯振动原因大致如下:SMC气控阀调节器输出信号不稳定。
快速的忽高忽低的变化,此时如阀门定位器灵敏度太高,则调节器输出微小的变化或飘移,就会立即转换成定位器输出信号很大。
致使阀振荡。
SMC气控阀的磨擦力太小,如调节阀的填料装得太少,或压盖没拧紧,外界输入信号有微小的变化或飘移,会立即传递给阀芯,使阀芯振动,并发出咯咯的响声。
