Ukuvula nokuvalwa kwevalve ngesandla, amandla agqithisileyo
Umphumo: i-valve iya konakaliswa ukuba ilula, kwaye ingozi yokhuseleko iya kubangelwa ukuba inzima
Imilinganiselo: i-valve ye-manual, i-handwheel yayo okanye i-handle, yenzelwe ngokuhambelana nabasebenzi abaqhelekileyo, ngokuqwalasela amandla okutywinwa kwendawo kunye namandla okuvala ayimfuneko. Ngoko ke, akuvumelekanga ukuhamba nge-lever ende okanye i-wrench ende. Abanye abantu basetyenziselwa ukusebenzisa i-wrench, kufuneka bahlawule ingqwalasela engqongqo, bangasebenzisi amandla amaninzi, ngaphandle koko kulula ukulimaza indawo yokutywina, okanye ukuphula i-handwheel kunye nokusingatha. Vula kwaye uvale i-valve, amandla kufuneka azinzile, kungekhona impembelelo. Ezinye iindawo zeevalvu zoxinzelelo oluphezulu ezinempembelelo yokuvula kunye nokuvala ziqwalasele amandla empembelelo kunye nevalve jikelele ayinakulinda. Kwivalve ye-steam, ngaphambi kokuvula, iya kufudunyezwa kwangaphambili kwaye amanzi adibeneyo aya kususwa. Xa uvula, kuya kucotha kangangoko kunokwenzeka ukuphepha ihamile yamanzi. Xa i-valve ivuliwe ngokupheleleyo, jika isondo lesandla emva kancinci, ukwenzela ukuba imicu iqinile ukuphepha ukukhululeka kunye nomonakalo. Kwiivalvu zesikhondo ezivulekileyo, khumbula ukuma kwesikhondo sevalve xa ivuleke ngokupheleleyo kwaye ivalwe ngokupheleleyo ukunqanda ukubetha iziko elingaphezulu elifileyo xa livuleke ngokupheleleyo. Kukulungele ukujonga ukuba iyinto eqhelekileyo xa ivalwe ngokupheleleyo. Ukuba i-ofisi yevalve iyawa, okanye i-sundry enkulu ifakwe phakathi kwe-valve core seals, indawo ye-valve stem iya kutshintsha xa ivalve ivalwe ngokupheleleyo. Xa umbhobho usetyenziswa okokuqala, kukho ukungcola okuninzi ngaphakathi, ngoko ivalve inokuvulwa kancinci. Isantya esiphezulu se-medium singasetyenziselwa ukuyihlamba, kwaye ke ingavalwa kancinci (ayikwazi ukuvalwa ngokukhawuleza okanye ngobundlobongela ukukhusela ukungcola okushiyekileyo ekulimazeni indawo yokutywinwa). Inokuvulwa kwakhona. Phinda kwakhona amaxesha amaninzi, coca ukungcola, kwaye emva koko ubeke ekusebenzeni okuqhelekileyo. Xa ivalve ivulwa ngokuqhelekileyo, kunokubakho ukungcola kumphezulu wokutywina. Xa ivaliwe, le ndlela ingentla iya kusetyenziswa ukuyihlamba icocekile, kwaye emva koko iya kuvalwa ngokusesikweni. Ukuba i-handwheel kunye nomqheba wonakele okanye ulahlekile, kufuneka zihambelane ngokukhawuleza, kwaye azikwazi ukutshintshwa yintsimbi eguquguqukayo, ukwenzela ukuba ugweme ukonakalisa amacala amane e-valve stem kunye nokusilela ukuvula nokuvala, okukhokelela kwiingozi kwimveliso. . Kweminye imidiya, xa ivalve ivaliwe kwaye ipholile ukucutha ivalve, umqhubi kufuneka ayivale kwakhona ngexesha elifanelekileyo ukugcina indawo yokutywina ingenamithungo emihle. Ngaphandle koko, imidiya igeleza kwii-seams ezintle kwisantya esiphezulu kwaye igubungele ngokulula indawo yokutywina. Ngexesha lokusebenza, ukuba kufunyaniswe ukuba umsebenzi unzima kakhulu, izizathu ziya kuhlalutywa. Ukuba ukupakisha kuqinile kakhulu, kunokukhululeka ngokufanelekileyo. Ukuba isiqu sevalve sigobile, abasebenzi baya kwaziswa ukuba basilungise. Kwezinye iivalve, xa zivaliwe, iindawo zokuvala zifudumala kwaye zandiswa, okwenza kube nzima ukuvula; ukuba kufuneka zivulwe ngeli xesha, banokukhulula intambo yebhonethi kwisiqingatha sesangqa ukuphelisa uxinzelelo lwesiqu sevalve, kwaye emva koko uhambise ivili lesandla.
