插裝閥基本組件

組件由閥芯、閥套、彈簧和密封圈組成。根據(jù)用途不同分為方向閥組件、壓力閥組件和流量閥組件。同一通徑的三種組件安裝尺寸相同，但閥芯的結(jié)構(gòu)形式和閥套座直徑不同。三種組件均有兩個(gè)主油口A 和B、一個(gè)控制口x 。

插裝閥在流體控制功能的領(lǐng)域的使用種類比廣泛，已應(yīng)用的元件有是電磁換向閥，單向閥，溢流閥，減壓閥，流量控制閥和順序閥。通用性在流體動(dòng)力回路設(shè)計(jì)和機(jī)械實(shí)用性的延伸，充分展示了插裝閥對(duì)系統(tǒng)設(shè)計(jì)者和應(yīng)用者的重要性。由于其裝配過(guò)程的通用性、閥孔規(guī)格的通用性、互換性的特點(diǎn)，使用插裝閥完全可以實(shí)現(xiàn)完善的設(shè)計(jì)配置，也使插裝閥廣泛地應(yīng)用于各種液壓機(jī)械。

以輪式裝載機(jī)為例，采用插裝閥集成塊來(lái)代替故障不斷、難以診斷和維修的動(dòng)力傳動(dòng)控制裝置。原有控制系統(tǒng)有60多個(gè)連接管件和19個(gè)元件。用來(lái)替代的整體特制集成塊上只有11個(gè)管件和17個(gè)元件。體積為12 x 4 x 5立方英寸，是原系統(tǒng)所占空間的20%。

比例控制技術(shù)是在開(kāi)關(guān)控制技術(shù)和伺服控制技術(shù)之間的過(guò)度技術(shù)，采用比例放大器控制比例電磁鐵，實(shí)現(xiàn)對(duì)比例閥的連續(xù)控制，從而實(shí)現(xiàn)對(duì)液壓系統(tǒng)壓力、流量、方向的無(wú)級(jí)調(diào)節(jié)；但是用比例閥進(jìn)行速度控制時(shí)，如果負(fù)載是變化的，那么執(zhí)行元件的速度就會(huì)受負(fù)載變化的影響，負(fù)載小時(shí)速度快，負(fù)載大時(shí)速度慢，于是在系統(tǒng)設(shè)計(jì)時(shí)，人們引用了壓力補(bǔ)償器，它可以使比例閥閥口的壓差保持恒定，使執(zhí)行元件的速度不受負(fù)載變化的影響。

比例換向插裝閥，先導(dǎo)式，帶集成電子元件 (OBE) 或外部控制電子元件

2WFC；2WFCE

2WFCE 型先導(dǎo)式比例方向閥主要包括：

封面 (1)

主舞臺(tái) (2)

帶比例電磁閥的先導(dǎo)控制閥 (3)

帶有位置傳感器和模擬接口 (4) 的集成電子設(shè)備或作為模塊放大器的外部控制電子設(shè)備

電子裝置（集成的或外部的）將****的控制值與主級(jí) (2) 的控制閥芯的位置實(shí)際值進(jìn)行比較。在控制偏差的情況下，先導(dǎo)控制閥 (3) 的電磁閥被激活。這樣，控制閥芯被調(diào)整。根據(jù)控制偏差，主級(jí) (2) 的控制室要么用先導(dǎo)油加壓（主級(jí)關(guān)閉），要么卸載（主級(jí)打開(kāi)）。行程和節(jié)流孔橫截面與控制值成比例地控制，直到控制偏差得到糾正。

電源電壓故障

如果較小電源電壓出現(xiàn)故障或低于較低電壓，則啟用將斷開(kāi)（僅接口 B1 和 G1），并且在電磁鐵導(dǎo)線斷線的情況下，電子設(shè)備將使先導(dǎo)控制閥 (3) 的電磁鐵斷電. 主級(jí) (2) 的控制閥芯使用端口 X 處的可用壓力和主級(jí)彈簧的力安全地移動(dòng)到其閥座，并阻止 A 和 B 之間的流動(dòng)。

流量控制功能

與壓力補(bǔ)償器結(jié)合使用時(shí)，先導(dǎo)式比例方向閥可用于流量的壓力補(bǔ)償控制。

順序閥

順序閥是一種利用壓力控制閥口通斷的壓力閥。

按控制油來(lái)源不同分內(nèi)控和外控，按彈簧腔泄漏油引出方式不同分內(nèi)泄和外泄。

順序閥的四種控制方式

通過(guò)改變上蓋或底蓋的裝配位置可得到內(nèi)控外泄、內(nèi)控內(nèi)泄、外控外泄、外控內(nèi)泄四種類型。

內(nèi)控外泄順序閥

內(nèi)控外泄順序閥與溢流閥非常相象:閥口常閉，進(jìn)口壓力控制，但是該

閥出口油液要去工作，所以有單獨(dú)的泄油口。

內(nèi)控外泄順序閥用于多個(gè)執(zhí)行元件順序動(dòng)作。其進(jìn)口壓力先要達(dá)到閥的調(diào)定壓力，而出口壓力取決于負(fù)載。當(dāng)負(fù)載壓力高于閥的調(diào)定壓力時(shí)，進(jìn)口壓力等于出口壓力，閥口全開(kāi);當(dāng)負(fù)載壓力低于調(diào)定壓力時(shí)，進(jìn)口壓力等于調(diào)定壓力，閥的開(kāi)口一定。
