Parker派克TDA系列比例節(jié)流閥是由三級(jí)組成。閥錐由座閥結(jié)構(gòu)的伺服閥芯進(jìn)行先導(dǎo)控制。帶力反饋的比例電磁閥調(diào)節(jié)伺服閥芯的位置。因此閥錐的位置不會(huì)受到壓差的影響。壓差可以達(dá)到最大的工作壓力。先導(dǎo)控制的控制油流量大約為1 l/min。工作的最低壓力為3 bar。控制壓力必須大于A口處系統(tǒng)壓力的25％。流量的調(diào)節(jié)精度為0.5％。由于流量特性曲線是漸進(jìn)的，因此當(dāng)小流量時(shí)，該調(diào)節(jié)精度在漸進(jìn)區(qū)域內(nèi)被改善為0.25％。整個(gè)行程的調(diào)節(jié)時(shí)間大約為25ms。當(dāng)油液由B向A流動(dòng)時(shí)，在關(guān)閉的初始位置上由B向A不能有泄漏。在該初始位置上先導(dǎo)控制不需要控制油。回油口T的壓力不能高于100 bar。

技術(shù)功能:

TDA 比例節(jié)流閥單元為3 級(jí)控制結(jié)構(gòu): 第一級(jí)為比例電磁鐵操控的閥芯/閥套結(jié)構(gòu)的先導(dǎo)級(jí), 第二級(jí)由控制彈簧和順序閥芯構(gòu)成, 主級(jí)則為閥芯、閥套組成的二通插件。比例電磁鐵推動(dòng)先導(dǎo)閥芯與控制彈簧的反饋力相平衡, 并由此控制順序閥芯的位置, 而主級(jí)閥芯則跟隨著順序閥芯動(dòng)作, 從而控制油口 B 至油口 A (油口 A 至 B 為可選項(xiàng)) 的開(kāi)口面積與電磁鐵的輸入電流成正比。主閥芯的位置與A、B 口的壓差無(wú)關(guān), 因此, 該壓差可與最高工作壓力一樣高。
