1. Okuvamileama-valve okuhlolafinyelela ukuvala okuqondile kuphela futhi kuvuleke futhi kuvalwe ngokuzenzakalelayo ngokusekelwe ekuhlukeni kwengcindezi kwe-medium. Azinawo umsebenzi wokulawula isivinini futhi zivame ukuthinteka uma zivaliwe. I-valve yokuhlola amanzi yengeza umklamo wokulwa nesando ovala kancane ngokusekelwe kumsebenzi wokunqamula. Ngokusebenzisa idivayisi ezinikele ukulawula isivinini sokuvala sediski yevalvu, inganciphisa umthelela wesando samanzi ngesikhathi sokugeleza emuva futhi ivikele imishini yesistimu.（Isithombe: DN1200ivalvu yokuhlola egobile enesando sobunzima）

2. Umehluko ekwakhiweni kwesakhiwo

I-valve yokuhlola evamile inesakhiwo esilula, esakhiwe umzimba we-valve, idiski, isihlalo se-valve kanye nendlela yokusetha kabusha (intwasahlobo noma amandla adonsela phansi). Ukuvulwa nokuvalwa kwayo kuncike ngokuphelele ekucindezelweni kwe-medium. I-valve yokuhlola evala kancane ephikiswayo enokumelana okuncane ifakwe indlela yokulawula ukuvala kancane (njenge-hydraulic damping kanye nezingxenye ze-spring buffer) ngenxa yalokhu, engavala ngezigaba (kuqala ivale ngokushesha ngo-70%-80%, bese ivala kancane ingxenye esele).

3. Ukumelana noketshezi kanye nokulawula isando samanzi

Ngenxa yemikhawulo yesakhiwo, ivalvu yokuhlola evamile inokumelana okukhulu phambili kanye nesivinini sokuvala esisheshayo (umzuzwana ongu-0.5 kuya ku-1), okungadala kalula isando samanzi esinzima, ikakhulukazi esibeka usongo olukhulu ezinhlelweni zokucindezela okuphezulu kanye nokugeleza okuphezulu. Ivalvu yokuhlola i-butterfly yehlisa ukumelana phambili (okungukuthi, "ukumelana okuncane") ngomklamo ohlelekile futhi yandisa isikhathi sokuvala sibe yimizuzwana emi-3-6, engalawula isando samanzi esiphezulu ngaphakathi kwengcindezi yokusebenza ephindwe ka-1.5 futhi yenze buthaka kakhulu umthelela.

4. Izimo ezahlukene ezisebenzayo

Ama-valve okuhlola ajwayelekile afaneleka ezimweni ezinomfutho ophansi (≤1.6MPa), ukugeleza okuncane (ububanzi bepayipi ≤DN200), kanye nokungazweli ku-water hammer, njengemipayipi yamagatsha yokuphakelwa kwamanzi asekhaya kanye nezindawo zokuphuma kwamanzi ezincane. I-valve engabuyi evala kancane futhi ephikelela kancane ifaneleka ezinhlelweni ezinomfutho ophezulu (≥1.6MPa) kanye nezinhlelo zokugeleza okukhulu (ububanzi bepayipi ≥DN250), njengokuphakelwa kwamanzi omlilo esakhiweni esinophahla oluphezulu, izindawo zokuphuma ezinkulu zokupompa, izinhlelo zamanzi ezijikeleza izimboni kanye nezinye izimo ezibalulekile.

5. Ukugcinwa Kwezinto Ezifanele kanye Nezindleko

Amavalvu okuhlola ajwayelekile awanazo izesekeli eziyinkimbinkimbi, anezinga eliphansi lokuhluleka, kulula ukuwanakekela futhi anezindleko eziphansi. Ngenxa yokuba khona kwendlela yokuvala kancane, ivalvu yokuhlola yokuvala kancane emelana nokumelana okuncane ingahlangabezana nezinkinga ezifana nokumanzisa ukuvuza kwamafutha kanye nokuguga kwentwasahlobo, okuholela ekuphindaphindeni kokugcinwa okuphezulu kancane kanye nezindleko. Kodwa-ke, uma ucabangela umsebenzi wokuvikela uhlelo jikelele, inikeza ukusebenza kwezindleko okungcono ezimweni ezibucayi.

Ngakho-ke, umehluko oyinhloko phakathi kwalezi ezimbili usekutheni zinomsebenzi wokulwa nokushaya okuvala kancane: ama-valve okuhlola ajwayelekile agxila ekuvalekeni okuyisisekelo, kuyilapho ama-valve okuhlola okuvala kancane okumelana nokumelana okuncane ethola ukumelana okuphansi kanye nokumelana nokushaqeka ngokwenza ngcono isakhiwo, okwenza kube ukukhetha okuthandwayo kwezinhlelo zokucindezela okuphezulu kanye nokugeleza okuphezulu.

Njengomkhiqizi wamavalvu onolwazi lweminyaka engama-20, i-Jinbin Valve ibilokhu iqinisekisa ikhwalithi yemikhiqizo nezinsizakalo zayo. Uma unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo zingakapheli amahora angama-24!
