單向節(jié)流閥R900433031 Z2S22-2-5X/ 技術(shù)結(jié)構(gòu)
單向節(jié)流閥是一種反向開啟可控的單向閥, 這類閥在冶金設(shè)備中應(yīng)用較為廣泛, 由于其結(jié)構(gòu)與原理的特殊性, 生產(chǎn)現(xiàn)場因液控單向閥使用不當(dāng)導(dǎo)致的故障經(jīng)常發(fā)生。
1、液控單向閥結(jié)構(gòu)與工作原理
液控單向閥結(jié)構(gòu)如圖1所示。當(dāng)控制油口不通壓力油時(shí),油液只能從PA→PB;當(dāng)控制油口通壓力油時(shí),正、反向的油液均可自由通過。當(dāng)油液反向流動(dòng)時(shí),閥芯的受力平衡表達(dá)式為:
pKAK-pAAK-FKM=pBA-pAA=Fs+Fs+W (1)
式中pK———控制油壓力,單位為N;
pA———反向出油腔油液壓力,單位為N;
pB———反向進(jìn)油腔油液壓力,單位為N;
FKM———控制活塞摩擦阻力,單位為N;
FM———錐閥芯總摩擦阻力,單位為N;
Fs———彈簧作用力,單位為N;
W———閥芯重量,單位為N;
AK———控制活塞面積,單位為m2;
A———閥座口面積,單位為m2。
當(dāng)略去控制活塞和錐閥芯的摩擦阻力時(shí), 則控制油壓力為:
pK=[(pB-pA)A+Fs+W]/AK+pA (2)
該值是保證油液反向流動(dòng)的控制油壓力。若閥口關(guān)閉,油液反向流動(dòng)停止,則出油腔壓力pA=0。根據(jù)控制活塞上腔的泄油方式不同分為內(nèi)泄式和外泄式。內(nèi)泄式也就是圖1所示的簡式液控單向閥。外泄式液控單向閥如圖2所示, 這種外泄式液控單向閥反向出油腔壓力pA只作用在控制活塞的上端, 與圖1結(jié)構(gòu)相比,作用面積要小得多,同時(shí),反向出油腔壓力油和控制壓力油泄漏到控制活塞上下段之間的容腔內(nèi),可通過外泄口直接引到閥體外,以避免由于泄漏油的聚積影響控制活塞的向上運(yùn)動(dòng), 故稱為外泄式液控單向閥。復(fù)式結(jié)構(gòu)液控單向閥如圖3所示,單向閥芯內(nèi)裝有卸載小閥芯。控制活塞上行時(shí)先頂開小閥芯使主油路卸壓,再頂開單向閥閥芯,其控制壓力僅為工作壓力的4.5%,沒有卸載小閥芯的液控單向閥的控制壓力為工作壓力的40%~50%。
