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

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.

Isimboli somgaqo wevalve yebhalansi ngolu hlobo lulandelayo;

Ngokudityaniswa kwevalve yolandelelwano kunye nevalve yokulinganisa kumfanekiso ongezantsi, izikimu ezininzi zokulawula ulungelelwaniso lwamazinga amakhulu okuqukuqela zinokufezekiswa. Ngexesha elifanayo, ukuba i-valve ye-balance balance isetyenzisiwe kwinqanaba lokulinga, iintlobo ezahlukeneyo zokudibanisa ukudibanisa ziyakwazi ukufezekiswa. Olu hlobo lwesikimu solawulo lunokwandisa kakhulu ingcamango yoyilo.

Ivalve yokulinganisa njengoxinzelelo lwevalve yokulinga uqhagamshelo olunxuseneyo:

Iinkqubo zolawulo ezahlukeneyo ziphunyezwa ngeevalvu zokulinganisa ezinxuseneyo ezinemilinganiselo yokulinga eyahlukeneyo. Iivalve ezimbini zokulinganisa ngokuthe ngqo kwi-Figure 4 ziquka ulawulo lwangaphambili. Umthwalo ongalunganga yi-valve yokulinga elawula umlinganiselo woxinzelelo ohlukeneyo we-2: 1 ivuliwe. Xa umthwalo ulungile, oko kukuthi, xa uxinzelelo kwi-inlet luphezulu kunoxinzelelo lomthwalo, i-valve ye-balance balance pre-controlled valve iya kwenziwa isebenze, kwaye ukuhluka koxinzelelo lokulawula kuphezulu kune-10: 1. Ukuze kuthintelwe i-valve ye-balance 10: 1 ekuvuleni kwindawo yomthwalo ongalunganga, kuya kubakho i-valve yokunciphisa uxinzelelo lwe-valve R (okwenene i-valve yokuphuphuma). Xa uxinzelelo lokungena luphezulu, i-valve yokunciphisa uxinzelelo lwe-R iyavula, kwaye i-valve ye-balance balance 10: 1 ifumana uphawu loxinzelelo lomqhubi ukuba luvule.

Ukusebenza kokulawula okwahlukileyo kunokufumaneka ngokulungelelanisa ivalve yokunciphisa uxinzelelo R.
