Eshabhu laseJinbin, elinye iqembu lamavalvu esango athambile avaliwe nge-flange selilungele ukuthunyelwa, kufaka phakathi isiqu esifihliwei-valve yesango ethambile evaliwe nge-flangekanye nevalvu yesango le-flange eliveziwe, enosayizi we-DN80 kanye ne-DN100, futhi yenziwe ngensimbi ephonswe nge-QT450. Njengabasebenzi bokuthenga kanye nokusebenza nokulungisa amapayipi, ukukhetha ivalvu yesango elithambile elivalwe kahle le-flange akugcini nje ngokuqeda izingozi zokuvuza kodwa futhi kwandise impilo yesevisi futhi kunciphise izindleko zokusebenza nokugcinwa. Uma uthenga, asikho isidingo sokuqhathanisa amanani ngokungaboni. Gxila emaphuzwini abalulekile: ukufanisa izimo zokusebenza, izinto ezisezingeni eliphezulu, izinqubo zokukhiqiza ezijwayelekile, kanye nensizakalo ethembekile yangemva kokuthengisa. Ungalandeli amanani aphansi ngokungaboni. Kuphela ngokulinganisa ikhwalithi kanye nokusebenza kwezindleko lapho ungakhetha khona ivalvu yesango elinobungane nelihlala isikhathi eside.

(isithombe: I-Non-Rising Stem Flange Soft-Sealing Gate Valve Dn100, I-Rising Stem Flange Soft-Sealing Gate Valve Dn80) 

Okokuqala, fanisa imingcele yesimo sokusebenza. Beka phambili ukuhlola ingcindezi yepayipi kanye nobubanzi. Ezinhlelweni zokuphakelwa kwamanzi kanye nokugeleza kwamanzi kanye nokuvikela umlilo, i-1.0/1.6 MPa ivame ukwanele. Kodwa-ke, ezimweni zokushisa okuphezulu kanye nengcindezi ephezulu, izinga lokumelana nengcindezi kumele lithuthukiswe. Ngesikhathi esifanayo, chaza ngokucacile uhlobo lwendawo yokusebenza. Izinto zokuvala ezahlukene zifanelekela amanzi ahlanzekile kanye nendle ukuvimbela ukugqwala kwezinto nokuguga okusheshayo. 

Okwesibili, naka ikhwalithi yomzimba we-valve kanye nesivalo.ivalvu yesango lamanziUmzimba kufanele wenziwe ngensimbi ethambile, eqinile futhi emelana nokuguquguquka. Gwema ukuthungwa okuphansi kwegobolondo elincane. Ukuvalwa okuthambile kuyisisekelo. Kunconywa ukukhetha izingxenye zokuvala ezihlanganisiwe ze-EPDM noma ze-NBR, ezinokuqina okuhle nokusebenza okuqinile kokuvala, ezingafinyelela ukuvuza okungenalutho, futhi zivimbele ukuvuza, ukuvuza kanye nezinkinga zokuvuza.

Ngaphezu kwalokho, naka isakhiwo kanye nobuciko. Khetha isakhiwo sesiqu esifihliwe, esithatha isikhala esincane futhi esingathambekele kakhulu ekuqongeleleni uthuli kanye nokugqwala. Ubuso be-flange kufanele bube bucwebe futhi bungabi namaphutha, bube nezimbobo zebholithi eziqondile ukuze kube lula ukufaka nokuxhuma endaweni. Isiqu se-valve yesango lokuvala kufanele sibe bushelelezi ngaphandle kokunamathela, okuvumela ukuvulwa nokuvalwa okulula, futhi akufanele sibambeke ngisho nangemva kokusetshenziswa isikhathi eside.

Okokugcina, naka iziqu kanye nensizakalo yangemva kokuthengisa. Cela imibiko yezinto ezibonakalayo kanye nezitifiketi zokuhlola, bese wenqaba imikhiqizo ngaphandle kolwazi. Beka phambili abakhiqizi ngensizakalo ephelele yangemva kokuthengisa, iziqinisekiso zekhwalithi ezicacile, kanye nezimpendulo ezisheshayo. Noma yiziphi izinkinga esikhathini esizayo zingaxazululwa ngokushesha. I-Jinbin Valve ibilokhu ikhiqiza ama-valve asezingeni eliphezulu iminyaka engama-20 (Umkhiqizi We-Gate Valve), enekhwalithi eqinisekisiwe. Uma unezidingo ezihlobene, sicela usithinte ngezansi. Uzothola impendulo zingakapheli amahora angama-24!
