射流管閥是液體能量轉(zhuǎn)換式放大器，屬于非節(jié)流式放大器，其工作原理與滑閥和噴嘴擋板閥有根本區(qū)別，它們都是節(jié)流式放大器，其靜特性的導(dǎo)出主要基于實(shí)驗(yàn)與推理。

滑閥和噴嘴擋板閥都是根據(jù)節(jié)流原理工作的，而射流管閥是根據(jù)壓力能與動(dòng)能轉(zhuǎn)換原理工作的。它們都是根據(jù)要求，由輸入量控制，將液壓源的流量、壓力通過控制閥送入液壓執(zhí)行元件中帶動(dòng)負(fù)載進(jìn)行位置、速度、加速度、力和壓力控制。

通常噴嘴擋板閥和射流管閥作前置級(jí)液壓放大器，如兩級(jí)伺服閥中的前置級(jí)，滑閥是三種液壓控制閥中經(jīng)常用的--種，如液壓控制系統(tǒng)中的液壓放大器、伺服閥、機(jī)液伺服機(jī)構(gòu)和液壓動(dòng)力機(jī)構(gòu)等都離不開滑閥。

通過對(duì)各種滑閥的穩(wěn)態(tài)性能分析和比較得知:四通閥有兩個(gè)節(jié)流口(控制口)同時(shí)工作控制對(duì)稱液壓缸，三通閥只有一個(gè)控制口工作控制差動(dòng)缸。

因此，四通閥的壓力增益比三通閥大- -倍，兩者的流量增益相同，故四通閥的流量--壓力系數(shù)比三通閥小--倍，四通閥比三通閥性能好。

同理，雙噴嘴擋板閥性能比單噴嘴擋板閥好，零開口閥效率高，線性差，流量增益小，正開口閥效率低，線性好，流量增益大。噴嘴擋板閥屬于正開口閥，所以正開口滑閥和噴嘴擋板閥適于作前置放大，零開口滑閥作前置放大和功率放大均可。

由于噴嘴擋板閥無摩擦，慣性力極小，其動(dòng)態(tài)性能和靈敏度遠(yuǎn)優(yōu)于滑閥。射流管閥由于結(jié)構(gòu)因素，抗污染能力強(qiáng)，工作可靠，壽命長(zhǎng)，這些又是滑閥和噴嘴擋板閥不可比擬的。

 

4WR...型比例控制閥

3.結(jié)構(gòu)和功能原理

先導(dǎo)控制閥型號(hào)3DREP 6... 該先導(dǎo)閥是一個(gè)由比例電磁鐵控制的三通減壓閥,它的作用是將一個(gè)輸入的電信號(hào)轉(zhuǎn)化為一個(gè)與其成比例的壓力輸出信號(hào),可用于所有的4WRZ..和5WR...型比例閥的控制。

比例電磁鐵是可調(diào)式,濕式直流電磁結(jié)構(gòu),帶中心螺紋,線圈可單獨(dú)拆卸;電磁鐵控制可通過外部放大器( WRZ型)或內(nèi)置的放大器( WRZE型)來實(shí)現(xiàn)。

結(jié)構(gòu):

該閥主要由下列部分組成:

(1)帶有安裝底面的殼體( 1 );

(2)裝有壓力測(cè)量活塞(3和4)的控制閥芯(2 );

(3)帶中心螺紋電磁鐵( 5和6);

(4)可選帶內(nèi)置放大器( 7 )

工作原理:

(1)當(dāng)電磁鐵(5和6)不帶電時(shí),對(duì)中彈簧將控制閥芯(2)保持在中位;

(2)比例電磁鐵帶電被激勵(lì)后, 會(huì)直接推動(dòng)控制閥芯( 2),例如:電磁”a” (5)被激勵(lì);

(3)控制閥芯(2)和壓力測(cè)量活塞(3)被推向左側(cè);

(4)位移與輸入的電信號(hào)成比例。

這時(shí),P口與B口及A口與T口通過閥芯與閥體形成的節(jié)流口1接通，節(jié)流特性為漸進(jìn)式。如果電磁鐵(5 )失電,控制閥芯( 2 )被彈簧重新推回中位。在先導(dǎo)閥的中位，A口、B口和T口相通,這也意味著油液可以從這里直接回油箱。

 

先導(dǎo)式比例方向閥, 型號(hào)4WRZ..和5WRZ.. , 4WRZ..型閥是先導(dǎo)式、比例電磁鐵

控制的四通方向閥,它可控制液流的方向和大小。

結(jié)構(gòu):

該閥主要由下列部分組成:

(1)裝有比例電磁. (5和6 )的先導(dǎo)控制閥( 9 )

(2)裝有主閥芯(11)和對(duì)中彈簧(12)的主閥(10)

工作原理:

(1)當(dāng)電磁鐵(5和6)不帶電時(shí),對(duì)中彈簧(12)將主閥芯(11)保持在中位。

(2)主閥芯(11)的動(dòng)作由先導(dǎo)閥(9)來控制-它會(huì)間接地被電磁鐵”b"(6)成比例地推動(dòng)。首先控制閥芯( 2 )被推向右側(cè),控制油經(jīng)過先導(dǎo)閥(9 )進(jìn)入控制腔( 13 )，并與輸入信號(hào)成比例地推動(dòng)主閥芯( 11 ), 這時(shí),P口與A口及B口與T口通過閥芯與閥體形成的節(jié)流口接通,節(jié)流特性為漸進(jìn)式。

(3)先導(dǎo)閥所需的控制油液可通過P口內(nèi)供或X口外供。

(4)如果電磁鐵(6)失電,控制閥芯( 2 )和主閥芯( 11 )會(huì)重新回到中位。

(5)隨著主閥芯位置的不同, P口與A口、B口與T口(R)接通或P口與B口、A口與T口(R)通�？蛇x保護(hù)罩手動(dòng)應(yīng)急操作( 14和15 ),它可使先導(dǎo)閥芯( 2 )在電磁不通電的情況下移動(dòng)。
