4WE6D62/EG220N9K4/V 24V开关电磁阀 

类型:直动式、先导式

作用:

(1)在不断溢流过程中保持系统压力恒定,起稳压和溢流作用(p,FP

系统’阀口常开) ;

(2)防止液压系统过载,起安全保护作用(p,=1.1~1.2p,max,阀口常闭)

(一)溢流阀的基本结构及其工作原理

1、直动式溢流阀

工作原理:

直接利用液压力与弹簧力相平衡以控制阀芯的启闭动作,从而保证进油口压力基本恒定。

特点:

①阀芯所受的液压力全靠弹簧力平衡,故当系统压力很高时,弹簧必须很硬,导致结构笨重,调压不轻便。一般用于压力小于2.5MPa的低压系统中,作安全阀或背压阀使用。

②由于惯性或负载的变化,导致q、变化,即开口度h的变化,由于k很大,所以p不稳定,稳压精度差;

③结构简单、便宜,但工作时易产生振动和噪音。

交流电磁铁:使用电压为交流110、220、380V。特点是启动力大,不需要专门的电源,吸合、释放快,动作时间约为0.01 ~0.03s。缺点是电源电压下降15%以上,电磁铁吸力明显减小,若衔铁不动作,干式电磁铁会在10~15min (湿式1~1.5h) 后烧坏线圈,且冲击及噪声大,寿命低,允许切换频率为10次1分。

直流电磁铁:使用电压为直流110和24V,工作可靠,吸合释放时间约为0.05~ 0.08s,切换频率般为120次/分,冲击小、体积小、寿命长,但需要专门的直流电源,成本高。

电磁阀的线圈是指电感器。是指导线一根一根绕起来,导线彼此互相绝缘,而绝缘管可以是空心的,也可以包含铁芯或磁粉芯,简称电感。电感又可分为固定电感和可变电感,固定电感线圈是由导线一圈靠一圈地绕在绝缘管上,导线彼此互相绝缘,而绝缘管可以是空心的,也可以包含铁芯或磁粉芯,简称电感或线圈。用L表示,单位有亨利(H)、毫亨利(mH)、微亨利(uH),1H=10^3mH=10^6uH。

电磁阀线圈的额定电压有DC12V、DC24V、AC24V(50/60Hz)、AC110V(50/60Hz)、AC220V(50/60Hz)、AC380V(50/60Hz)。一般在电气设计时要么采用AC220V(不需加装开关电源,成本低、线路简单而便于维护)、要么采用DC24V(常用的的安全电压、开关电源/电磁阀线圈都易于维修更换)。

检测电磁阀好坏的方法:先给电磁阀通上被控制的介质(带压力的液体、气体<空气>,压力值为电磁阀使用压力范围的中间值),再给电磁阀线圈通电,如果被控制介质有从通到断或从断到通的状态的变化,那么电磁阀就是好的,否则就是有问题的。

WE 型号的方向阀为电磁线圈操作的方向滑阀。这些阀控制流体的启动、停止和方向。

这些方向阀主要由壳体 (1)、一个或两个线圈 (2)、控制阀芯 (3) 和一个或两个复位弹簧 (4) 组成。

在断电情况下,控制阀芯 (3) 由复位弹簧 (4) 固定在中心位置或初始位置(脉冲阀芯除外)。控制阀芯 (3) 由液压油 (2) 中带湿式插脚的线圈启动。

要确保正常运行,必须注意将线圈的压力腔注满液压油。

线圈 (2) 的力通过推杆 (5) 作用在控制阀芯 (3) 上并将后者从其静止位置推到所需的终端位置。这可实现 P → A 和 B → T 或 P → B 和 A → T 的必要流向。

线圈 (2) 断电后,复位弹簧 (4) 会将控制阀芯 (3) 推回其静止位置。

手动应急操作 (6) 可在线圈不通电的情况下移动控制阀芯 (3)。

不带弹簧复位“O”(仅可使用符号 A、C 和 D)

这种型号为带两个阀芯位置和两个线圈且不带定位设备的方向阀。在断电情况下,阀芯位置不确定。

不带弹簧复位,带有定位设备“OF”(脉冲阀芯,仅可使用符号 A、C 和 D)

这种型号为带两个阀芯位置、两个线圈和一个定位设备的方向阀。它轮流锁定两个阀芯位置,因此线圈无需永 久通电。

注意:

由于设计原因,阀门难免会存在内部泄漏,且泄漏量会随着使用寿命的延长而增加。

先导式安全阀是依靠从导阀排出的介质来驱动或控制的。而导阀本身是一个直接作用式安全阀,有时也采用其他形式的阀门。先导式安全阀适用于高压、大口径的场合。先导式安全阀的主阀还可以设计成依靠工作介质来密封的形式,或者可以对阀瓣施加比直接作用式安全阀大得多的机械载荷,因而具有良好的密封性能。同时,它的动作很少受背压的影响。这种安全阀的缺点在于它的可靠性同主阀和导阀有关,动作不如直接作用式安全阀那样迅速、可靠,而且结构较复杂。

阀门在串联使用时,随着开度变化,,阀前后压差也有变化,因此使阀门的工作特性曲线偏离理想特性。如果管路阻力大,直线性会变成快开特性,而丧失调节能力。等百分比特性将变成直线特性。小流量情况下,由于很少有管路阻力,上述特性畸变就不大了,对等百分比特性,实际上也就没有必要。从制造的角度来说, Cv =0.05以下时,也不可能再产生等百分比的侧面形状。因此,对小流量阀主要的问题是如何将流量控制在所需要的范围之内。
