Ivalve yehydraulic balance valve Excavator hydraulic cylinder valve core CBIA-LHN

Ukuhlelwa kweevalvu zokunceda

Ngokwesakhiwo kunye nomsebenzi wevalve yokunceda, inokwahlulwa ibe zezi ntlobo zilandelayo:
Ivalve yokunciphisa uxinzelelo
Ivalve yokunciphisa uxinzelelo isetyenziswa ikakhulu ukunciphisa uxinzelelo oluphezulu kwinkqubo ye-hydraulic. Xa uxinzelelo kwinkqubo ye-hydraulic idlula
Xa ixabiso lokusetha kwangaphambili lisetyenzisiwe, i-spool iya kuvula i-port ephuphumayo, kwaye uxinzelelo oludlula ixabiso lokusetha kwangaphambili luya kukhutshwa nge-port yokuphuphuma. Ngokuqhelekileyo isetyenziswa kwiinkqubo
Kuyimfuneko ukukhusela olona xinzelelo luphezulu lwamacandelo e-hydraulic ukunqanda umonakalo kumalungu e-hydraulic ngenxa yezihlandlo zoxinzelelo olugqithisileyo lwe-hydraulic.
Ivalve yoncedo rhoqo
Ivalve yokuphelisa ukuqukuqela rhoqo isetyenziselwa ukukhawulelana nokuhamba kolwelo kunye nokuthintela ukuhamba okugqithisileyo kwisixokelelwano sobuchwephesha be-hydraulic ekonakalisweni kwamalungu olwelo. Xa ukuhamba kwenkqubo kudlula ixabiso elibekwe ngaphambili, i-spool iya kuvula i-port ephuphumayo, kwaye ukuhamba okugqithise kwixabiso lokusetha kwangaphambili kuya kukhutshwa nge-port yokuphuphuma. Ihlala isetyenziswa kwiinkqubo apho ukuhamba kwamanzi kufuneka kuthintelwe, njengoomatshini bokubumba inaliti, oomatshini bokusika kunye noxinzelelo lwe-hydraulic.
Masilinde.
Ivalve yoncedo eneendawo ezimbini
I-valve yokunceda indawo ezimbini i-valve yokunceda eguquguqukayo, ngokujikeleza ngesandla isixhobo sokulungelelanisa, unokutshintsha ukulayishwa kwangaphambili kwe-valve core. Ngokwamandla ahlukeneyo okulayisha kwangaphambili, i-spool iya kuvula ngokuzenzekelayo okanye ivale i-port ephuphumayo, ngaloo ndlela iqonda uxinzelelo okanye umda wokuhamba kwinkqubo ye-hydraulic. Ihlala isetyenziswa kwiimeko apho kufuneka ukulawulwa ngesandla koxinzelelo okanye ukuhamba.
Shwankathela
Ivalve yokunceda yinto eqhelekileyo yokulawula i-hydraulic, isetyenziselwa ukukhawulela okanye ukulawula uxinzelelo oluphezulu kwi-hydraulic system. Umgaqo wayo wokusebenza ngokuvulwa ngokuzenzekelayo kunye nokuvalwa kwe-spool, eya kudlula uxinzelelo lwe-hydraulic olusethiweyo okanye umgca wokuhamba.
Ukongeza kwinkqubo, ngaloo ndlela ikhusela amacandelo e-hydraulic ukusuka kuxinzelelo oluphezulu okanye umonakalo wokuhamba.
Iindidi ezahlukeneyo zeevalve zokunceda zisetyenziselwa kwiimeko ezahlukeneyo zenkqubo ye-hydraulic, kwaye ukusebenza kwazo kunye neeparamitha nazo zihluke. Kuyilo lwenkqubo ye-hydraulic kunye nokugcinwa kwabasebenzi, ukhetho oluchanekileyo kunye nokulawulwa kwevalve yokunceda kubaluleke kakhulu.
