Zeziphi iimeko ezifanelekileyo iivalvu zokutshekisha?

Njengesixhobo esiphambili sokuthintela ukubuya umva okuphakathi,khangela iivalvezisetyenziswa kakhulu kwimizi-mveliso, kuluntu, nakwimimandla ekhethekileyo. Umsebenzi wabo ophambili kukukhusela ukhuseleko lwezixhobo, ukugcina uzinzo lwenkqubo, kunye nokuphepha iingozi. Kwintsimi yoshishino, ii-valve zokutshekisha zingathintela umva we-high-temperature kunye ne-high-pressure media kwimibhobho yeoli kunye negesi, ukuthintela umngcipheko wokuqhuma okubangelwa ukungalingani koxinzelelo lwepayipi; Kwimveliso yeekhemikhali, inokuthintela i-reflux ye-corrosive or high viscosity fluids, ukuphepha ukubola kwezixhobo okanye ukuvaleka. Ngokomzekelo, ukufakela iivalve zokujonga kwindawo yokungena kunye nokuphuma kwe-reactor kunokuthintela ukuguquguquka koxinzelelo ekubangeleni ukujikeleza okuphakathi, ukuqinisekisa iimeko zokuphendula ezizinzileyo; Inkqubo ye-boiler feed water kumashishini ombane ixhomekeke kwiivaluvu zokutshekisha ukukhusela i-hammer phenomenon yamanzi. Ukuba amanzi abuyela emva xa impompo yamanzi imisiwe, iya kuba nefuthe kwi-impeller kwaye yonakalise umzimba wempompo.Khangela iivalvuinokuqinisekisa ukuhamba kwamanzi ngendlela enye kunye nokuqinisekisa ukusebenza okuqhubekayo kwenkqubo.

Kwiimeko zoluntu,ciivalve heck ziyafuneka kuthungelwano lonikezelo lwamanzi kwisakhiwo esiphakamileyo ukuthintela isando samanzi. Xa impompo yamanzi iyema ngequbuliso, inertia yokuqukuqela kwamanzi iya kwenza ukothuka koxinzelelo, konakalise umbhobho kunye neevalvu. Iivalve zokujonga zinokuvala ngokukhawuleza umva kwaye ziphelise ingozi efihlakeleyo yehamile yamanzi; Ukufaka iivalvu zokuhlola kwiinkqubo zamanzi zasemakhaya kunokuthintela ugutyulo ekubeni lungcolise amanzi acocekileyo. Ngokomzekelo, ukufaka iivalve zokujonga kwindawo yokuphuma kwezifudumezi zamanzi elanga kunokuthintela amanzi ashushu ukuba abuyele kumbhobho wamanzi abandayo, ukuqinisekisa ukhuseleko lwamanzi.

Ngokweenjongo ezikhethekileyo, izixhobo zokukhupha ityuwa emanzini olwandle zisebenzisa iivalvu zokuhlola ukuthintela ukubuya kwamanzi olwandle kunye nokukhusela izixhobo ekudlekeni; Ukufakela i-valve yokukhangela kwindawo yokuphuma kwe-compressor yomoya kunokuthintela umoya oxinzelelweyo ukuba ungabuyeli ngasemva kwaye ubangele ukuba i-compressor ibuyele umva, ngaloo ndlela iphucula ukusebenza kakuhle kwenkqubo; I-valve yokukhangela ifakwe kwindawo yokuphuma kwisikhululo sokupompa imibhobho yamanzi ekude ukuthintela imidiya esezantsi ukuba ibuyele kwisikhululo sokupompa esinyukayo, ukuqinisekisa ukuqhubeka kokuthutha; Umbhobho wenkqubo yomphunga uxhomekeke kwiivalvu zokutshekisha ukuthintela ukujiya okanye ukubuya komphunga, ukunciphisa umngcipheko wehamile yamanzi, nokugcina umgangatho womphunga.
