Ivalve ye-hydraulic balance Excavator hydraulic cylinder spool CXHA-XBN

Ubume bevalve yokulinganisela kunye nomgaqo wokusebenza

Ivalve ye-hydraulic balance valve ivumela ioli ukuba ihambe ngokukhululekileyo ukusuka kwi-port 2 ukuya kwi-1. inxalenye eluhlaza ihambela kwi-port 1 phantsi kwe-drive yoxinzelelo lwe-liquid, kwaye i-valve yokukhangela ivuliwe, kwaye ioli inokuhamba ngokukhululekileyo ukusuka kwi-port 2 ukuya kwi-port 1.

Ukuhamba ukusuka kwi-port 1 ukuya kwi-port 2 ivaliwe kude kube yilapho uxinzelelo lwe-pilot port lufikelela kwixabiso elithile kwaye i-spool eluhlaza okwesibhakabhaka ihanjiswe ngakwesobunxele ukuze ivule i-valve port ukuze i-oyile ihambe ukusuka kwi-port 1 ukuya kwi-2.

Izibuko liyavala xa uxinzelelo lomqhubi wenqwelomoya lungonelanga ukuvula i-spool eluhlaza okwesibhakabhaka. Ukuhamba ukusuka kwi-port 1 ukuya kwi-port 2 kunqunyulwa.
Umgaqo wokusebenza kwevalvu ye-hydraulic:
Isekethe yokulinganisa kunye nevalve yokulandelelana kwe-unidirectional. Lungisa i-valve yokulandelelana ukwenzela ukuba imveliso yoxinzelelo lwayo lokuvula kunye nommandla obambeleyo wegumbi elisezantsi le-cylinder ye-hydraulic cylinder inkulu kancinane kunobunzima beendawo ezihamba ngokuthe nkqo. Xa i-piston ihla, ngenxa yokuba kukho uxinzelelo oluthile lomva kwi-oyile yokubuyisela isiphaluka ukuxhasa umthwalo womxhuzulane, i-piston iya kuwa kakuhle kuphela xa inxalenye ephezulu yepiston inoxinzelelo oluthile; Xa ivalve yokubuyisela umva ikwindawo ephakathi, ipiston iyayeka ukuhamba kwaye ayiqhubeki phantsi. Ivalve yolandelelwano apha ikwabizwa ngokuba yivalve yebhalansi. Kule luphu yokulinganisela, i-valve yokulandelelana ihlengahlengiswa emva kokuba uxinzelelo lubekwe. Ukuba umsebenzi uya uba mncinci. Uxinzelelo lwempompo kufuneka lunyuswe, oluya kwandisa ukulahlekelwa kwamandla kwenkqubo. Ngenxa yokuvuza kwangaphakathi kwe-valve yokulandelelana kunye ne-valve yokubuyisela i-valve ye-valve yesilayidi, kunzima ukwenza i-piston imise i-statically kuyo nayiphi na indawo ixesha elide, eliya kubangela ukuba isixhobo somthwalo we-gravity sityibilike. Ke ngoko, le sekethe ifanelekile kumthwalo womsebenzi ulungisiwe kwaye iimfuno zokutshixa i-hydraulic cylinder piston azikho phezulu.
