Hydraulic balance valve Excavator hydraulic cylinder spool PBHB-LCN

Iivalvu zeHydraulic zahlulahlulwe kakhulu ngokweendidi ezine: ngevalve, ivelufa yokhuseleko, ivelufa yolawulo kunye nevalve yendlela. Okokuqala, makhe siqonde ivalve. Ivalve edlulayo (ekwaziwa ngokuba yivalve ngokubanzi okanye ivalve yokuvala) yeyona ixhaphakileyo kwi-hydraulic system, esetyenziselwa ukulawula ukuphuma kolwelo kwaye inoxanduva lokuvula nokuvala ulwelo ngaphakathi. inkqubo yehydraulic. Olona phawu luphambili lwevalvu sisakhiwo esilula, kulula ukusisebenzisa, sisetyenziswa kakhulu kwimveliso yezolimo kunye nemveliso ye-hydraulic system.

Okwesibini, makhe sijonge iivalvu zokhuseleko. Ivalve yokhuseleko (ekwaziwa ngokuba yivalve yokukhulula okanye ivalve yokugcwala) licandelo elibalulekileyo kwinkqubo yoxinzelelo lwamanzi ukukhusela ukhuseleko lwezixhobo kunye nabasebenzi. Xa uxinzelelo kwinkqubo ye-hydraulic idlula ixabiso elimiselweyo, i-valve yokhuseleko iya kuvula ngokukhawuleza, ukwenzela ukuba ulwelo olugqithisileyo lukhutshwe nge-port ephuphumayo, ngaloo ndlela ikhusela inkqubo kunye nezixhobo emonakalweni. Ivalve yokhuseleko ibonakaliswa ngummiselo woxinzelelo oluzenzekelayo kunye nokuthembeka okuphezulu, okudlala indima ebaluleke kakhulu kwinkqubo ye-hydraulic.

Uhlobo lwesithathu lwevalve yehydraulic yivalve yokulawula. Ivalve yokulawula isetyenziselwa ukulawula uxinzelelo, ukuhamba kunye nesalathiso solwelo kwinkqubo ye-hydraulic, ukuze kufezekiswe ulawulo oluchanekileyo lwenkqubo. Iimpawu eziphambili zevalve yokulawula ziyisakhiwo esiyinkimbinkimbi kunye nemisebenzi eyahlukeneyo, esetyenziswa ngokubanzi kwi-industrial production automation system. Kukho iintlobo ezininzi zeevalve zokulawula, iivalve eziqhelekileyo zokunceda, iivalve zokulawula ulwalathiso, iivalve zokulawula ukuhamba njalo njalo. Ivalve nganye yokulawula ineempawu zayo kunye nezicelo, kwaye inokukhethwa ngokweemfuno zangempela.
