Umgaqo-siseko oSebenzayo kunye neMimandla yokuSebenza yeNkonyana eliLingwayo lokuHlola
2024-03-071. Umgaqo osebenzayo wevalve yokujonga ilinge
Iivalve yokujonga ilingeyivalve yendlela enye elawulwa ngamanzi. Umgaqo wayo wokusebenza kukusebenzisa intsebenziswano esondeleyo phakathi kwesiseko sevalvu kunye nesitulo sevalvu ukuphumeza ulawulo lokuhamba kwendlela enye. Ivalve ithatha ulawulo lolingo, oko kukuthi, ukuvuleka kwelinye icala levalve kulawula ukungena nokuphuma kweoyile esebenza ngoxinzelelo lwendalo ngevalve yokulinga ukuqonda ulawulo londoqo wevalve kwisitulo sevalve. Xa i-oyile ye-hydraulic ingena isuka kwindawo yokungena, uxinzelelo oluthile lufakwa phezulu, lubangela ukuba i-valve core ivuleke ezantsi, kwaye ulwelo luhamba kumjelo ophakathi. Ngeli xesha, igumbi lokulawula elidityaniswe ekuqaleni kwitshaneli livaliwe. Xa i-oyile ye-hydraulic iphuma kwi-port B, uxinzelelo lwe-oyile kwi-valve core luyakhululwa, kwaye i-valve core iya kuvala ngokukhawuleza ukuze i-oyile ye-hydraulic ingaphinde ibuyele.
2. Umsebenzi wevalve yokujonga ilinge
Umsebenzi oyintloko we-valve yokuhlola i-pilot kukuthintela ukuhamba ngasemva kweoli ye-hydraulic, ngaloo ndlela iqinisekisa ukusebenza okuqhelekileyo kwenkqubo ye-hydraulic kunye nokhuseleko kunye nokuthembeka komsebenzi. Xa inkqubo ye-hydraulic iyeka ukusebenza, i-valve yokuhlola i-pilot inokugcina uxinzelelo, oko kukuthi, ukuthintela umthwalo kumatshini ukuba ubuyele emva kombhobho we-hydraulic. Kwinkqubo ye-hydraulic, i-valve yokujonga i-pilot ivame ukufakwa kwicala eliphezulu loxinzelelo lomgca weoli. Isetyenziswa ikakhulu ukuthintela ukubuya umva kweoyile ye-hydraulic kwinkqubo yehydraulic kunye nokuthintela ukulahleka koxinzelelo kunye nokuvuza kweoyile.
3. Ingaba ivalve yokujonga ilinge inokwenza isilinda sizitshixe?
Ngokuqhelekileyo, i-valve yokujonga i-pilot-operated check valves ayikwazi ukwenza ukuba i-cylinder ifezekise umsebenzi wokuzitshixa, kuba i-self-locking ye-cylinder kufuneka idibaniswe nezixhobo ezifana nokutshixa ngomatshini okanye imida yokuqhubela phambili. Ivalve yokujonga ilinge enye kuphela yamacandelo olawulo lwesixokelelwano se-hydraulic. Isetyenziselwa ikakhulu ukuthintela ukuhamba ngasemva kweoyile ye-hydraulic kunye nokukhusela inkqubo. Ayinakuthatha indawo yamacandelo omatshini ukufezekisa ukuzitshixa kwe-cylinder.
Ukushwankathela, i-valve yokuhlola i-pilot ibalulekile i-valve yendlela enye elawulwa nge-hydraulically, esetyenziswa kakhulu ukukhusela ukuguqulwa kweoli ye-hydraulic kunye nokuqinisekisa ukhuseleko kunye nokuthembeka kwenkqubo ye-hydraulic. Nangona kunjalo, ukufaka nje ivalve yokujonga i-pilot ayikwenzi ukuba isilinda sifezekise umsebenzi wokuzivalela. Kufuneka zidityaniswe nezixhobo ezifana nokutshixa ngoomatshini okanye imida yokuqhubela phambili.
4.Iindawo zokusetyenziswa kweevalvu ezisetyenziswayo ezilingwayo
Iivalvu eziqhutywa ngumqhubi wenqwelomoya zisetyenziswa ngokubanzi kulawulo nolawulo kwiisistim zehydraulic, kubandakanywa kodwa kungaphelelanga nje kule mimandla ilandelayo:
Izixhobo zoomatshini: Iivalve ze-pilot zingasetyenziselwa kwinkqubo yokuhanjiswa kwe-hydraulic yezixhobo zoomatshini ukulawula ukuhamba kwe-cylinder ye-hydraulic ukulawula u-clamping, ukubeka kunye nenkqubo yokwenza umsebenzi we-workpiece.
Izixhobo zesinyithi: Ii-valve ze-pilot zingasetyenziselwa kwiinkqubo ze-hydraulic kwizixhobo ze-metallurgical ukulawula ukuhamba kwee-cylinders ze-hydraulic kunye neesilinda ze-oyile ukulawula nokulungelelanisa ii-steelmaking furnaces, i-rolling mills kunye nezinye izixhobo.
Umatshini wokubumba inaliti yeplastiki: I-valve ye-pilot ingasetyenziselwa kwinkqubo ye-hydraulic yomshini wokubumba inaliti yeplastiki ukulawula uxinzelelo kunye nesantya ngexesha lenkqubo yokubumba i-injection ukufezekisa ukuqhutyelwa kunye nokubunjwa kweemveliso zeplastiki.
Oku kungentla kukweminye imimandla yokusetyenziswa kweevalvu zolingo kwiinkqubo zoxinzelelo lwamanzi. Ngapha koko, iivalve zokulinga zikwasetyenziswa ngokubanzi kwezinye iindawo ezininzi, ezigquma izixhobo ezahlukeneyo zoomatshini kunye nokusetyenziswa kwemizi-mveliso.
