DIFVE02BCVXW25 派克电磁阀 美国派克优质商品 原装进口 低价销售 正确产品特价
我公司专业代理博世力士乐(BOSCH-REXROTH)、阿托斯ATOS、派克Parker、迪普马DUPLOMATIC、油研YUKEN;本特利bentley、贝加莱B&R、西门子、光洋KOYO,美国ASCO,美国PARKER派克 美国伊顿威格士VICKERS泵阀 日本大金DAIKIN电磁阀 美国艾尔泰克电磁阀 美国阿泰克电磁阀 等系列进口产品
DIFVE02BCVXW25 派克电磁阀 美国派克优质商品 原装进口 电磁阀通常与单作用气动执行机构配套使用,两位是两个位置可控:开-关,三通是有三个通道通气,一般情况下1个通道与气源连接,另外两个通道1个与执行机构的进气口连接,1个与执行机构排气口连接,具体的工作原理可以参照单作用气动执行机构的工作原理图。
两位五通电磁阀通常与双作用气动执行机构配套使用,两位是两个位置可控:开-关,五通是有五个通道通气,其中1个与气源连接,两个与双作用气缸的外部气室的进出气口连接,两个与内部气室的进出气口接连,具体的工作原理可参照双作用气动执行机构工作原理
在气路(或液路)上来说,两位三通电磁阀具有1个进气孔(接进气气源)、1个出气孔(提供给目标设备气源)、1个排气孔(一般安装一个****,如果不怕噪音的话也可以不装@_@)。 两位五通电磁阀具有1个进气孔(接进气气源)、1个正动作出气孔和1个反动作出气孔(分别提供给目标设备的一正一反动作的气源)、1个正动作排气孔和1个反动作排气孔(安装****)。
对于小型自动控制设备,气管一般选用8~12mm的工业胶气管。在电气上来说,两位三通电磁阀一般为单电控(即单线圈),两位五通电磁阀一般为双电控(即双线圈)。线圈电压等级一般采用DC24V、AC220V等。 两位三通电磁阀分为常闭型和常开型两种,常闭型指线圈没通电时气路是断的,常开型指线圈没通电时气路是通的。 常闭型两位三通电磁阀动作原理:给线圈通电,气路接通,线圈一旦断电,气路就会断开,这相当于“点动”。 常开型两位三通单电控电磁阀动作原理:给线圈通电,气路断开,线圈一旦断电,气路就会接通,这也是“点动”。 两位五通双电控电磁阀动作原理:给正动作线圈通电,则正动作气路接通(正动作出气孔有气),即使给正动作线圈断电后正动作气路仍然是接通的,将会一直维持到给反动作线圈通电为止。 给反动作线圈通电,则反动作气路接通(反动作出气孔有气),即使给反动作线圈断电后反动作气路仍然是接通的,将会一直维持到给正动作线圈通电为止。这相当于“自锁”。 基于两位五通双电控电磁阀的这种特性,在设计机电控制回路或编制PLC程序的时候,可以让电磁阀线圈动作1~2秒就可以了,这样可以保护电磁阀线圈不容易损坏。
REXROTH电磁阀,德国力士乐电磁阀,Rexroth电磁阀电磁阀在液路系统中用来实现液路的通断或液流方向的改变,它一般具有一个可以在线圈电磁力驱动下滑动的阀芯,阀芯在不同的位置时,电磁阀的通路也就不同。阀芯的工作位置有几个,该电磁阀就叫几位电磁阀:阀体上的接口,也就是电磁阀的通路数,有几个通路口,该电磁阀就叫几通电磁阀。 电磁阀安装后,一般所有接口都应该是连接好了的,所谓工作位置指的是阀芯的位置。阀芯在线圈不通电时处在甲位置,在线圈通电时处在乙位置,阀芯在不同位置时,对各接口起到或接通或封闭的作用。
电磁阀二位是指电磁阀的阀芯有两个不同的工作位置(开、关)。 电磁阀二通、三通指电磁阀的阀体上有两个、三个通道口; 比如二位二通电磁阀是一进一出(二个通道、较普通常见) 二位三通电磁阀控制液体是一进二出(两出分别是一个常开一个常闭);气动换向电磁阀是一进一出一排气;液压一进一出一回油。
国内外的电磁阀从原理上分为三大类(即:直动式、分步直动式、先导式),而从阀瓣结构和材料上的不同与原理上的区别又分为六个分支小类(直动膜片结构、分步重片结构、先导膜式结构、直动活塞结构、分步直动活塞结构、先导活塞结构)。
直动式电磁阀:
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。

在液压传动系统中,控制油液压力高低的液压阀称之为压力控制阀,简称压力阀。这类阀的共同点是利用作用在阀芯上的液压力和弹簧力相平衡的原理工作的。
一、溢流阀的基本结构及其工作原理
溢流阀的主要作用是对液压系统定压或进行安全保护。
(一)溢流阀的作用和性能要求
1.溢流阀的作用
在液压系统中用来维持定压是溢流阀的主要用途。它常用于节流调速系统中,和流量控制阀配合使用,调节进入系统的流量,并保持系统的压力基本恒定。用于过载保护的溢流阀一般称为安全阀。
2.液压系统对溢流阀的性能要求
(1)定压精度高
(2)灵敏度要高
(3)工作要平稳且无振动和噪声
(4)当阀关闭时密封要好,泄漏要小。
(二)溢流阀的结构和工作原理
常用的溢流阀按其结构形式和基本动作方式可归结为直动式和先导式两种。
1.直动式溢流阀
直动式溢流阀是依靠系统中的压力油直接作用在阀芯上与弹簧力等相平衡,以控制阀芯的启闭动作,溢流阀是利用被控压力作为信号来改变弹簧的压缩量,从而改变阀口的通流面积和系统的溢流量来达到定压目的的。当系统压力升高时,阀芯上升,阀口通流面积增加,溢流量加大,进而使系统压力下降。溢流阀内部通过阀芯的平衡和运动构成的这种负反馈作用是其定压作用的基本原理,也是所有定压阀的基本工作原理。
2.先导式溢流阀
图-19所示为先导式溢流阀的结构示意图,由于先导阀芯一般为锥阀,受压面积较小,所以用一个刚度不太大的弹簧即可调整较高的开启压力,用螺钉调节导阀弹簧的预紧力,就可调节溢流阀的溢流阀压力。
先导式溢流阀有一个远程控制口K,如果将K口用油管接到另一个远程调压阀(远程调压阀的结构和溢流阀的先导控制部分一样),调节远程调压阀的弹簧力,即可调节溢流阀主阀芯上端的液压力,从而对溢流阀的溢流压力实现远程调压。但是,远程调压阀所能调节的较高压力不得超过溢流阀本身导阀的调整压力。当远程控制口K通过二位二通阀接通油箱时,主阀芯上端的压力接近于零,主阀芯上移到较高位置.阀口开得很大。由于主阀弹簧较软,这时溢流阀p口处压力很低,系统的油在低压下通过溢流阀流回油箱,实现卸荷。
(三)溢流阀的性能
溢流阀的性能包括溢流阀的静态性能和动态性能。
1.静态性能
(1)压力调节范围
压力调节范围是指调压弹簧在规定的范围内调节时,系统压力能平稳地上升或下降,且压力无突跳及迟滞现象时的较大和较小调定压力。溢流阀的较大允许流量为其额定流量,在额定流量下工作时溢流阀应无噪声、溢流阀的较小稳定流量取决于它的压力平稳性要求,一般规定为额定流量的15%。
(2)启闭特性
启闭特性是指溢流阀在稳态情况下从开启后到闭合的过程中,被控压力与通过溢流阀的溢流量之间的关系。它是衡量溢流阀定压精度的一个重要指标,一般用溢流阀处于额定流量、调定压力ps时,开始溢流的开启压力pk及停止溢流的闭合压力pB分别与ps的百分比来衡量,前者称为开启比,后者称为闭合比。
(3)卸荷压力
当溢流阀的远程控制口及与油箱相连时,额定流量下的压力损失称为卸荷压力。

比例控制阀主要用於开回路控制(open loop co****ol);比例控制阀的输出量与输入信号成比例关系,且比例控制阀内电磁线圈所产生的磁力大小与电流成正比。
在传统型式的液压控制阀中,只能对液压进行定值控制,例如:压力阀在某个设定压力下作动,流量阀保持通过所设定的流量,方向阀对於液流方向通/断的切换。因此这些控制阀组成的系统功能都受到一些限制,随著技术的进步,许多液压系统要求流量和压力能连续或按比例地随控制阀输入信号的改变而变化。液压伺服系统虽能满足其要求,而且精度很高,但对於大部分的工业来说,他们并不要求系统有如此高的品质,而希望在保证一定控制性能的条件下,同时价格低廉,工作可靠,维护简单,所以比例控制阀就是在这种背景下发展起来的。
比例控制阀可分为压力控制阀,流量控制及方向控制阀三类。
压力控制阀:用比例电磁阀取代引导式溢流阀的手调装置便成为引导式比例溢流阀,其输出的液压压力由输入信号连续或按比例控制。
流量控制阀:用比例电磁阀取代节流阀或调速阀的手调装置而以输入信号控制节流阀或调速阀之节流口开度,可连续或按比例地控制其输出流量。故节流口的开度便可由输入信号的电压大小决定。
方向控制阀:比例电磁阀取代方向阀的一般电磁阀构成直动式比例方向阀,其滑轴不但可以换位,而且换位的行程可以连续或按比例地变化,因而连通油口间的通油面积也可以连续或按比例地变化,所以比例方向控制阀不但能控制执行元件的运动方向外,还能控制其速度。
