4WREE..型比例控制閥

1.結(jié)構(gòu)和功能原理

該二位四通和三位四通比例方 向閥為直控,板式結(jié)構(gòu);由比例電磁操作,比例電磁.帶中心螺紋,圈可單獨拆卸,電磁的控制可通過外部放大器( WRA型)或內(nèi)置的放大器(WRAE型)實現(xiàn)。

結(jié)構(gòu):

該閥由下列部分組成:

帶安裝底面的閥體( 1 )

帶彈簧(3和4)的控制閥芯(2 )

帶中心螺紋的電磁鐵( 5和6 )

位移傳感器(7 )

可選帶內(nèi)置放大器( 8 )

機械零位調(diào)整(9 ),

工作原理:

電磁鐵(5和6 )不帶電時,對中彈簧(3和4 )將控制閥芯(2 )保持在中位

比例電磁鐵得電被激勵后,會直接推動控制閥芯( 2),例如:控制電磁"b" (6 )被激勵，控制閥芯(2)被推向左側(cè),位移與輸入電信號成比例,這時,P口至A口及B口至T口通過閥芯與閥體形成的節(jié)流溝通并具有漸進的流量特性。電磁鐵( 6 )失電控制.閥芯(2)被對中彈簧(3)重新推回中位。

在電磁鐵失電的情況下,閥芯( 2 )在電磁跌復(fù)位彈簧的作用保持在機械中位。這對機能符號”V”的閥芯來說,與液壓中位無關(guān)!當(dāng)閥用于閉環(huán)控制而關(guān)閉時,閥芯則置于液壓中位。

必須避免回油管路中的油全部排空, 必要時在回路中安裝背壓閥(背壓約2 bar)。

 

電液比例閥是采用了比例控制技術(shù),介于開關(guān)型液壓閥和電液伺服閥之間的-種液壓元件,在工業(yè)生產(chǎn)中獲得了廣泛的應(yīng)用,輸入的電信號有模擬式和數(shù)字式兩大類,可以用于控制位置(轉(zhuǎn)角)、速度(轉(zhuǎn)速)、加速度(角加速度)、壓力(壓差)、力(力矩)等參數(shù)。電液比例閥等元件可以組成如下三類控制回路和系統(tǒng)

(1)電液比例壓力控制回路和系統(tǒng)。例如:用于帶鋼熱連軋機卷取機液壓輔助系統(tǒng)的電液比例壓力控制回路,用于板帶軋機輥縫控制的液壓推上系統(tǒng)電液比例壓力控制回路,用于帶材卷取設(shè)備恒張力的閉環(huán)電液比例壓力控制回路;

(2)電液比例流量控制回路和系統(tǒng)。例如:用于帶鋼熱連軋機精軋機平衡液壓系統(tǒng)的電液比例壓力控制回路,用于機床微進給的電液比例控制回路,用于旋壓機折板機同步的電液比例控制回路,用于電梯的電液比例控制回路;

(3)電液比例多參數(shù)控制回路和系統(tǒng)。例如:用于帶鋼熱連軋機精軋換輥液壓系統(tǒng)的電液比例壓力控制回路,用于液壓缸垂直配置而采用wI型閥芯的比例控制回路,用于熱軋鋼卷步進鏈式運輸機的速度、加減速度控制回路。

力士樂REXROTH比例方向閥，先導(dǎo)操作

力士樂REXROTH二位四通和三位四通比例方向閥，直動式，不帶電氣位置反饋，不帶集成式放大版（OBE）4WRZ

液壓閥是用來控制液壓系統(tǒng)中油液的壓力、流量和液體流動方向。

二、液壓閥的分類

按功能分:

方向控制閥(單向閥、換向閥)

壓力控制閥(溢流閥、減壓閥、順序閥、壓力繼電器)

流量控制閥(節(jié)流閥、調(diào)速閥)

按操縱方式分:

手動和腳踏、機動、電動、液動、電液動等。

共同點

(1) 在結(jié)構(gòu)上，所有的閥都有閥體、閥芯(轉(zhuǎn)閥或滑閥)和驅(qū)使閥芯動作的部件(如彈簧、電磁鐵)組成。

(2)在工作原理上，所有閥的開口大小，閥進、出口壓差以及流過閥的流量之間的關(guān)系都符合孔口流量公式，僅是各種閥控制的參數(shù)各不相同而已。

三、對液壓閥的基本要求

(1)動作靈敏，使用可靠，工作時沖擊和振動小。

(2)油液流過的壓力損失小。

(3)密封性能好。

(4)結(jié)構(gòu)緊湊，安裝、調(diào)整、使用、維護方便，通用性大。
