Namuhla, iJinbin ikwethula ivalvu yebhabhathane kagesi enobubanzi obukhulu. Le valve yebhabhathane inomklamo we-bypass futhi ifakwe kokubili amadivayisi kagesi kanye namasondo esandla. Imikhiqizo esesithombeni yileamavalvu ebhabhathaneenobukhulu be-DN1000 kanye ne-DN1400 ekhiqizwe yi-Jinbin Valves.

Amavalvu ebhabhathane amakhulu ane-bypass (ngokuvamile abhekisela kububanzi obujwayelekile be-DN≥500) angamavalvu akhethekile afaka amapayipi e-bypass kanye namavalvu amancane okulawula emzimbeni wevalvu yamavalvu ebhabhathane avamile. Umsebenzi wawo oyinhloko ukulinganisela umehluko wokucindezela we-medium ngaphambi nangemva kwevalvu ngokusebenzisa i-bypass, ukuxazulula izinkinga ekuvulekeni, ekuvaleni nasekusebenzeni kwamavalvu amakhulu.

Izinzuzo zokuklama i-bypass ye-actuator kagesi enkulu ububanzi be-butterfly valve

1. Nciphisa ukumelana kokuvula nokuvala futhi uvikele uhlelo lokushayela: Uma ama-valve amakhulu evulwa futhi evalwa ngqo, umehluko wokucindezela phakathi kwemidiya yangaphambili neyangemuva mkhulu, okungakhiqiza kalula i-torque enkulu futhi kubangele ukugcwala ngokweqile kanye nomonakalo kudivayisi yokushayela kagesi/yomoya. I-valve ye-bypass ingavulwa kusengaphambili ukuze ivumele i-medium ukuthi igeleze kancane ukuze ilinganise umehluko wokucindezela, inciphise i-torque yokuvula nokuvala ye-valve eyinhloko ngaphezu kuka-60% futhi yandise kakhulu impilo yesevisi yesistimu yokushayela.

2. Nciphisa ukuguguleka kwezivalo: Uma umehluko wokucindezela umkhulu kakhulu, i-medium ithambekele ekuthinteni ubuso bokuvala bevalvu eyinhloko, okubangela ukuguqulwa nokuguguleka kwezivalo futhi kuholele ekuvuzeni. Ngemva kokulinganisela ingcindezi, ubuso bokuvala bevalvu eyinhloko bungaba sebuthintaneni noma ekuhlukaneni okubushelelezi, futhi impilo yesevisi yezingxenye zokuvala ingandiswa izikhathi ezimbili kuya kwezingu-3.

3. Gwema ukushaywa yisando samanzi: Emapayipini amakhulu, ukuvulwa nokuvalwa kwamavalvu ngokuzumayo kungabangela kalula isando samanzi (ukuphakama nokwehla kwengcindezi ngokuzumayo), okungase kuphule ipayipi noma kulimaze imishini. Ivalvu edlulayo ilawula kancane kancane izinga lokugeleza, okungavimbela ukuguquguquka kwengcindezi ngempumelelo futhi kuqede ingozi yesando samanzi.

4. Thuthukisa ukulula kokulungisa: Uma ivalvu eyinhloko idinga ukuhlolwa nokulungiswa, asikho isidingo sokuvala lonke uhlelo. Vele uvale ivalvu eyinhloko bese uvula ivalvu ye-bypass ukuze ugcine ukugeleza okuyisisekelo kwe-medium futhi unciphise ukulahlekelwa kwesikhathi sokungasebenzi komkhiqizo.

Lokhuivalvu yebhabhathane elijiyilekuvame ukusetshenziswa ezimweni ezilandelayo:

1. Ukuhlinzekwa kwamanzi kamasipala kanye nokugeleza kwamanzi: Amapayipi amakhulu okuhambisa amanzi ezitshalweni zamanzi kanye namapayipi amakhulu okuhambisa amanzi angcolile asemadolobheni (DN500-DN2000) kudingeka alungise njalo izinga lokugeleza kwamanzi. Ukudlula kungavimbela umthelela kunethiwekhi yamapayipi ngesikhathi sokuvulwa nokuvalwa.

2. Imboni ye-Petrochemical: Kumapayipi okuthutha uwoyela ongahluziwe kanye namafutha acwengisisiwe (ngaphansi kwezimo zokucindezela okuphezulu), amavalvu ebhabhathane amakhulu adinga ukuhlonyiswa ngamavalvu okudlula ukuze kuvinjelwe umthelela ophakathi ezingxenyeni zokuvala nokuqinisekisa ukuphepha kwezokuthutha.

3. Izitshalo zamandla okushisa/zenuzi: Uhlelo lwamanzi olujikelezayo (ububanzi obukhulu bamapayipi amanzi okupholisa), i-bypass ingalawula ukugeleza kwamanzi kahle futhi ivimbele ukulimala kwesando samanzi emishinini ebalulekile efana nama-condenser.

4. Amaphrojekthi okonga amanzi: Iziteshi ezinkulu zokuphambukisa amanzi kanye namapayipi amakhulu okunisela adinga amavalvu amakhulu ukuze alawule umthamo wamanzi. Ukudlula kungaqinisekisa ukuvulwa nokuvalwa okubushelelezi futhi kuvikele isakhiwo sesiteshi.

I-Jinbin Valve (Abakhiqizi be-Butterfly Valve) ineminyaka eminingi yesipiliyoni ekukhiqizeni ama-butterfly valve amakhulu futhi iklama ngokukhethekile futhi ihlele ngezifiso izixazululo zesicelo se-valve kumakhasimende. Uma unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo zingakapheli amahora angama-24!
