Namuhla, endaweni yokusebenzela iJinbin, umshini wokuhlanza amanziivalvu yesango lommeseenosayizi we-DN1800 isipakishiwe futhi manje isithuthwa iye lapho iya khona. Leli sango lommese selizosetshenziswa engxenyeni engaphambili yeyunithi yokukhiqiza ugesi wamanzi esiteshini sikagesi wamanzi ngezinjongo zokulungisa, kuchazwe kabusha amazinga emboni ngokusebenza kwayo okuhle kakhulu kanye nokuzivumelanisa nendawo.

Le valve yesango le-flange knife ifinyelele intuthuko enkulu ekusebenzeni okuyinhloko. Umzimba wevalvu wenziwe ngensimbi yekhabhoni i-Q355B, kanti ipuleti levalvu lenziwe ngensimbi engagqwali i-304. Lihlanganiswe nezinto zokuvala irabha ye-nitrile, ezingagcini nje ngokufeza umphumela wokuvala ongenawo ukuvuza kodwa futhi ezidlula kude ukumelana nengcindezi yemikhiqizo evamile. Ivalvu yesango lensimbi yommese ehlanganisiwe enobubanzi obufanayo ngokuvamile ingamelana nengcindezi yamandla engamakhilogremu angu-1.5 kanye nengcindezi yokuvala engamakhilogremu angu-1, kuyilapho lo mkhiqizo ungamelana nengcindezi yamandla engamakhilogremu angu-9 kanye nengcindezi yokuvala engamakhilogremu angu-6, okunikeza isiqinisekiso esiqinile semisebenzi yokulungisa ngaphansi kwezimo zokucindezela okuphezulu.

Ukuphendula izinselele zokusebenza kwama-valve eziteshini zikagesi zamanzi, ukusungulwa komkhiqizo kufaka phakathi ukwakheka kwe-bypass. Uma ama-valve endabuko evaliwe, umehluko wokucindezela kuzo zombili izinhlangothi mkhulu, okungaholela kalula ebunzimeni ekuvulekeni. Kodwa-ke, lo mklamo ungaqala i-bypass ngaphambi kokuvula i-valve eyinhloko ukuze ulinganisele ukucindezela kuzo zombili izinhlangothi, kunciphisa kakhulu ukumelana kokusebenza futhi kuthuthukise ukusebenza kahle kokulungisa.

Okubaluleke kakhulu ukunakwa uhlelo lwayo lokwenza ngcono indawo. Uma sibheka indawo encane yokufaka endaweni yamakhasimende aseYurophu, ithimba le-R&D lashiya umklamo wenduku eveziwe evamile futhi lasebenzisa isakhiwo senduku esifihliwe, okuvumela induku yepiston yesilinda kawoyela ukuthi ixhunywe ngqo epuletini levalvu, kwasuswa isidingo samabhuleki endabuko. Lokhu kunciphisa ukuphakama kwemishini okungenani ngamamitha ayi-1.8, kwavumelana ngokuphelele nezimo zokufakwa ezincane.

Izinto ezintsha eziningi zale valve enkulu yesango lommese azigcini nje ngokubhekana nezinkinga ezingokoqobo ekunakekelweni kweziteshi zamandla kagesi, kodwa futhi zibonisa ukuzivumelanisa nezimo okunembile komklamo wobuchwepheshe, okunikeza inketho entsha yokuthuthukisa imishini yeziteshi zamandla kagesi kagesi. Njengomkhiqizi wamavalvu onolwazi lweminyaka engu-20, i-Jinbin Valve inokusekelwa okuqinile kobuchwepheshe futhi inikeza izixazululo ezithembeke kakhulu ngokusekelwe ezidingweni zangempela zamakhasimende. Uma unemibuzo ehlobene, sicela usithinte ngezansi futhi uzothola impendulo zingakapheli amahora angu-24! (Intengo Yevalvu Yesango Leslayidi)
