1.Okuvamilehlola ama-valvefinyelela kuphela ukuvala unidirectional futhi uvule futhi uvale ngokuzenzakalelayo ngokusekelwe umehluko wengcindezi ophakathi. Azinawo umsebenzi wokulawula isivinini futhi zijwayele ukuba nomthelela lapho zivaliwe. I-valve yokuhlola amanzi yengeza umklamo wokulwa nesando ovala kancane ngesisekelo somsebenzi wokusika. Ngokusebenzisa idivayisi ezinikele ukulawula isivinini sokuvala sediski ye-valve, inganciphisa umthelela wesando samanzi ngesikhathi sokubuyela emuva futhi ivikele imishini yesistimu.（Isithombe:DN1200i-valve yokuhlola etshekisayo enesando sesisindo）

2.Umehluko ekubunjweni kwesakhiwo

I-valve yokuhlola evamile inesakhiwo esilula, esihlanganisa umzimba we-valve, i-disc, isihlalo se-valve kanye nomshini wokusetha kabusha (intwasahlobo noma amandla adonsela phansi). Ukuvulwa nokuvalwa kwayo kuncike ngokuphelele ekuphokopheni kwe-medium. Ivalvu yesheke evala kancane evala kancane ukumelana ne-micro ifakwe indlela yokulawula evala kancane (efana ne-hydraulic damping kanye ne-spring buffer components) kulesi sisekelo, engavala ngezigaba (okokuqala ivale ngokushesha 70% -80%, bese ivala kancane kancane ingxenye esele).

3.I-Fluid Resistance kanye nokulawula isando samanzi

Ngenxa yokulinganiselwa kwesakhiwo, i-valve yokuhlola evamile inokumelana okukhulu okuhamba phambili kanye nesivinini sokuvala ngokushesha (i-0.5 kuya ku-1 isekhondi), okungase kubangele kalula isando samanzi esinzima, ikakhulukazi esibeka usongo oluphawulekayo ku-high-pressure kanye nezinhlelo zokugeleza okuphezulu. I-valve yokuhlola i-butterfly inciphisa ukumelana phambili (okungukuthi, "ukumelana ne-micro-resistance") ngokusebenzisa umklamo ohlelekile futhi yandisa isikhathi sokuvala kumasekhondi angu-3-6, engakwazi ukulawula isando samanzi esiphezulu ngaphakathi kwezikhathi ezingu-1.5 zokucindezela kokusebenza futhi senze buthaka kakhulu umthelela.

4.Izimo ezisebenzayo ezihlukene

Ama-valve okuhlola avamile afaneleka ezimweni ezinengcindezi ephansi (≤1.6MPa), ukugeleza okuncane (ububanzi bepayipi ≤DN200), nokungezwani nesando samanzi, njengamapayipi egatsha okunikezwa kwamanzi asekhaya kanye nezindawo zokushisisa amanzi ezincane. I-micro-resistance evala kancane i-valve engabuyi ifaneleka ku-high-pressure (≥1.6MPa) kanye nokugeleza okukhulu (ububanzi bepayipi ≥DN250) izinhlelo, ezifana nokuhlinzekwa kwamanzi omlilo wezakhiwo eziphakeme, izindawo ezinkulu zepompo, izinhlelo zamanzi ezijikelezayo zezimboni nezinye izimo ezibucayi.

5.Isondlo kanye Nezindleko

Ama-valve okuhlola ajwayelekile awanazo izesekeli eziyinkimbinkimbi, anezinga eliphansi lokuhluleka, kulula ukuwagcina futhi anezindleko eziphansi. Ngenxa yobukhona bomshini ovala kancane, i-valve yesheke evala kancane ukumelana ne-micro-resistance ingase ihlangabezane nezinkinga ezifana nokuvuza kukawoyela okudambisa kanye nokuguga kwentwasahlobo, okubangela imvamisa yokulungisa ephezulu kancane kanye nezindleko. Kodwa-ke, uma kucatshangelwa wonke umsebenzi wokuvikela uhlelo, inikeza ukusebenza okungcono kwezindleko ezimeni ezibucayi.

Ngakho-ke, umehluko oyinhloko phakathi kwalokhu okubili ulele ekutheni banomsebenzi wokulwa nesando ovala kancane yini: ama-valve okuhlola ajwayelekile agxila ekuvaleni okuyisisekelo, kuyilapho ama-micro-resistance avala kancane ama-valve okuhlola afinyelela ukumelana okuphansi nokumelana nokushaqeka ngokusebenzisa ukuthuthukiswa kwesakhiwo, okuwenza abe yinketho ekhethwayo yezinhlelo zokucindezela okuphezulu nokugeleza okuphezulu.

Njengomkhiqizi wamavalvu onokuhlangenwe nakho kweminyaka engama-20, i-Jinbin Valve ibilokhu iqinisekisa ikhwalithi yemikhiqizo namasevisi ayo. Uma unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo kungakapheli amahora angama-24!
