Namuhla, u-Jinbin wethula ivalve yovemvane kagesi enobubanzi obukhulu. Le valve yovemvane inomklamo we-bypass futhi ifakwe womabili amadivayisi kagesi nawesandla. Imikhiqizo esesithombeni yileizivalo uvemvaneenobukhulu be-DN1000 kanye ne-DN1400 ekhiqizwe ama-Jinbin Valves.

Amavalvu ovemvane anobubanzi obukhulu anama-bypass (ngokuvamile abhekisela kububanzi obuncane begama DN≥500) amavalvu akhethekile anezela amapayipi okudlula kanye namavalvu okulawula amancane kumzimba wamavalvu wamavalvu ovemvane avamile. Umsebenzi wabo oyinhloko ukulinganisa umehluko wokucindezela we-medium ngaphambi nangemva kwe-valve ngokusebenzisa i-bypass, ukuxazulula izinkinga ekuvuleni, ukuvala nokusebenza kwama-valve amakhulu.

Izinzuzo zokuklama i-bypass ye-valve yovemvane ye-actuator kagesi enobubanzi obukhulu

1. Yehlisa ukumelana nokuvula nokuvala futhi uvikele uhlelo lokushayela: Uma ama-valve anobubanzi obukhulu evulwa futhi evaliwe ngokuqondile, umehluko wengcindezi phakathi kwemidiya yangaphambili nangemuva mkhulu, ongakwazi ukukhiqiza kalula i-torque enkulu futhi kubangele ukugcwala ngokweqile nokulimala kudivayisi kagesi/i-pneumatic drive. I-valve ye-bypass ingavulwa kusengaphambili ukuze ivumele i-medium ukuba ihambe kancane ukuze ilinganise umehluko wokucindezela, ukunciphisa i-torque yokuvula nokuvala ye-valve eyinhloko ngaphezu kwe-60% futhi yandise kakhulu impilo yesevisi yesistimu yokushayela.

2. Yehlisa ukuguga kwezimpawu: Uma umehluko wengcindezi mkhulu kakhulu, okuphakathi kuthambekele ekubeni nomthelela endaweni yokuvala yevalvu eyinhloko, kubangele ukuguquguquka nokuguga kwezimpawu futhi kuholele ekuvuzeni. Ngemuva kokudlula ukulinganisa ukucindezela, indawo yokuvala ye-valve eyinhloko ingaba ukuxhumana okushelelayo noma ukuhlukaniswa, futhi impilo yesevisi yezingxenye zokuvala inganwetshwa izikhathi ezi-2 kuya kwezi-3.

3. Gwema umthelela wesando samanzi: Emapayipini anobubanzi obukhulu, ukuvuleka nokuvala okungazelelwe kwamavalvu kungabangela kalula isando samanzi (ukukhuphuka nokuwa komfutho), okungase kubhodloze ipayipi noma kulimaze okokusebenza. I-valve ye-bypass ilawula kancane izinga lokugeleza, elingase libe yimpumelelo ukushintshashintsha kwengcindezi futhi lisuse ingozi yesando samanzi.

4. Thuthukisa ukunethezeka kokulungisa: Lapho i-valve eyinhloko idinga ukuhlolwa nokulungiswa, asikho isidingo sokuvala lonke uhlelo. Vele uvale i-valve eyinhloko bese uvula i-valve yokudlula ukuze ugcine ukugeleza okuyisisekelo kwe-medium futhi unciphise ukulahlekelwa kwesikhathi sokuphumula sokukhiqiza.

Lokhui-valve ye-butterfly ene-flangedngokuvamile isetshenziswa kulezi zimo ezilandelayo:

1. Ukuhlinzekwa kwamanzi kamasipala kanye nokukhipha amanzi: Amapayipi amakhulu okuthutha amanzi ezimbonini zamanzi kanye namapayipi amakhulu okukhuculula indle asemadolobheni (DN500-DN2000) adinga ukulungisa izinga lokugeleza njalo. I-Bypass ingavimbela umthelela kunethiwekhi yamapayipi ngesikhathi sokuvulwa nokuvala.

2. Imboni ye-petrochemical: Kuwoyela ongahluziwe kanye namapayipi okuthutha kawoyela acolisisiwe (ngaphansi kwezimo zokucindezela okukhulu), amavalvu ovemvane anobubanzi obukhulu kudingeka afakwe ama-bypass valves ukuze avimbele umthelela omaphakathi ezingxenyeni zokuvala futhi aqinisekise ukuphepha kwezokuthutha.

3. Izitshalo zamandla ashisayo/amandla enuzi: Uhlelo lwamanzi ajikelezayo (ububanzi obukhulu bamapayipi amanzi okupholisa), i-bypass ingalawula kahle ukugeleza kwamanzi futhi ivimbele ukulimala kwesando samanzi emishinini ebalulekile njengama-condensers.

4. Amaphrojekthi wokonga amanzi: Amashaneli amakhulu okuphambukisa amanzi kanye namapayipi okunisela amakhulu adinga amavalvu anobubanzi obukhulu ukuze alawule umthamo wamanzi. I-Bypass ingaqinisekisa ukuvulwa nokuvala okushelelayo futhi ivikele isakhiwo sesiteshi.

I-Jinbin Valve (Abakhi Bevaluvu Bovemvane) inokuhlangenwe nakho kweminyaka eminingi ekwenzeni amavalvu ovemvane anobubanzi obukhulu futhi idizayina ngokukhethekile futhi yenze ngendlela oyifisayo izixazululo zokufaka amavalvu kumakhasimende. Uma futhi unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo kungakapheli amahora angama-24!
