Iivalvu ze-overcenter eyodwa zolu chungechunge ziyilelwe ukuqinisekisa uzinzo kwindawo yokusebenza ye-hydraulic actuator enomthwalo onqunyanyisiweyo, kunye nokulawula intshukumo yayo kwicala elinye kuphela (ngokuqhelekileyo isigaba sokwehla), ukushiya icala elichaseneyo lilawulwa yi-free flow; ngenxa ye-BSPP-GAS i-threaded port, inokufakwa kwi-line kwi-hydraulic system.
Ngokutyisa umgca ochasene nomthwalo, umgca we-pilot ulawula ukuvulwa kwenxalenye yeshaneli yokwehla evumela ukulawulwa kwentshukumo ye-actuator kunye nokuphepha i-phenomenon ye-cavitation ngokubonga kwisenzo sokuchasa amandla okutsala. Umngxuma olinganisiweyo udambisa isignali yokulinga ukuze ivalvu ivuleke kwaye ivale ngokulinganayo, kuthintelwa ukujikeleza komthwalo. Ivalve eyengaphezulu enye iphinda isebenze njengevalve yokunqanda ukothuka kubukho boxinzelelo oluphezulu olubangelwa ziimpembelelo okanye imithwalo egqithisileyo. Ukuze oku kwenzeke, umgca wokubuyela kwi-distributor kufuneka uxhunywe kwi-drain. I-valve ehlawulelwe isiqingatha: uxinzelelo olushiyekileyo kumgca wokubuya aluchaphazeli ukusetwa kwevalvu ngelixa benyusa amaxabiso okulinga.
Ukusetyenziswa kolu hlobo lwevalve ke ngoko kunokwenzeka kwiinkqubo ezine-DCV ene-spool yeziko elivaliweyo. I-hydraulic leakproof luphawu olusisiseko kwiivalvu ezingaphezulu. Ukuqinisekisa ukusebenza kakuhle, i-Oleoweb ivelisa izixhobo zangaphakathi zeevalvu zayo kwintsimbi ephezulu, eqinile kwaye igayiwe, kwaye, ngexesha lenkqubo yokuvelisa, ihlola ngokucophelela imilinganiselo kunye nokunyamezela kwejometri yezinto zokutywinwa, kunye nesitywina ngokwayo. ivalve edibeneyo. ngamalungu-ngaphakathi-i-valve emzimbeni: onke amacandelo afakwe ngaphakathi kwe-hydraulic manifold, isisombululo esivumela ukulawula amazinga aphezulu okuhamba ngelixa unciphisa imilinganiselo yonke.
I-manifold yenziwe ngetsimbi yoxinzelelo lokusebenza ukuya kwi-350 bar (5075) kunye nokuxhatshazwa okuphezulu; ikhuselwe ekumdleni ngonyango lwe-zinc plating kwaye yenziwe ngoomatshini kubuso obuthandathu ukwenzela ukuphunyezwa okusebenzayo ngakumbi kwonyango olungaphezulu. Ngezicelo ezivezwe ngokukodwa kwiiarhente ezindlongo ezindlongo (umz. izicelo zaselwandle) unyango lweZinc-Nickel luyafumaneka xa ulucelile. Iivaluvu zifumaneka kubungakanani beBSPP 3/8 "kunye neBSPP 1/2" kumazinga okusebenza acetyiswayo ukuya kuthi ga kwi-60 lpm (15,9 gpm). Iinkalo ezahlukeneyo zokulinganisa kunye nemilinganiselo yokulinga. Ukusebenza kakuhle, kuyacetyiswa ukuba usete i-overcenter. iivalve kwixabiso le-30% ephezulu kunomthwalo omkhulu wokusebenza.
