Namhlanje, kwindawo yokusebenzela ye-Jinbin, i-hydraulicivelufa yesango lemelaenobungakanani be-DN1800 ipakishwe kwaye ngoku ithuthwa ukuya kwindawo yayo. Eli sango lemela liza kufakwa kwisiphelo esingaphambili seyunithi yokuvelisa umbane wamanzi kwisikhululo sombane oqhutywa ngamanzi ngeenjongo zokulondolozwa, ukucacisa ngokutsha imigangatho yoshishino kunye nokusebenza kwalo okugqwesileyo kunye nokuziqhelanisa nokuqhelaniswa nendawo.

Le valve yesango lemela yeflange iphumelele impumelelo enkulu ekusebenzeni okungundoqo. Umzimba we-valve wenziwe nge-carbon steel Q355B, kwaye ipleyiti ye-valve yenziwe ngensimbi engenasici 304. Idibaniswe kunye nezinto zokutywinwa kwerubha ye-nitrile, engaphumeleli kuphela isiphumo sokutywinwa kwe-zero-leakage kodwa iphinda idlulele ukunyanzeliswa koxinzelelo lweemveliso eziqhelekileyo. Cast steel imela isango ivelufa yobubanzi efanayo idla kuphela ukumelana noxinzelelo amandla 1.5 neekhilogram kunye noxinzelelo lokutywina 1 kilogram, lo gama le mveliso unako ukumelana noxinzelelo lwamandla 9 neekhilogram kunye nokutywinwa koxinzelelo lweekhilogram ezi-6, enika isiqinisekiso esiluqilima sokugcinwa kwemisebenzi phantsi kweemeko zoxinzelelo oluphezulu.

Ukuphendula kwimingeni yokusebenza kweevalvu kwizikhululo zombane wamanzi, imveliso entsha ibandakanya uyilo lwe-bypass. Xa iivalve zemveli zivaliwe, umahluko woxinzelelo kuzo zombini iziphelo mkhulu, onokukhokelela ngokulula kubunzima bokuvula. Nangona kunjalo, olu yilo lunokuqalisa i-bypass ngaphambi kokuvula i-valve ephambili ukulungelelanisa uxinzelelo kwiiphelo zombini, ukunciphisa kakhulu ukuxhatshazwa kokusebenza kunye nokuphucula ukusebenza kakuhle kokugcinwa.

Eyona nto ifanele ukuqwalaselwa ngakumbi sisicwangciso sayo sokwandisa indawo. Ngokuthathela ingqalelo indawo enyiniweyo yofakelo lwendawo kubathengi baseYurophu, iqela leR&D lilushiyile uyilo oluqhelekileyo lwentonga oluveziweyo laza lamkela isakhelo sentonga efihliweyo, sivumela intonga yepiston yesilinda seoli ukuba idityaniswe ngokuthe ngqo kwipleyiti yevalvu, ishenxisa imfuno yezibiyeli zemveli. Oku kunciphise ukuphakama okupheleleyo kwezixhobo ubuncinane ubuncinane be-1.8 yeemitha, ukulungelelanisa ngokufanelekileyo kwiindawo zokufakela ezidibeneyo.

Ukwenziwa kwezinto ezininzi ezintsha kwesi sivalu sesango esikhulu semela akwaneli nje ukujongana neendawo ezibuhlungu ezisebenzayo kugcino lwezikhululo zombane wamanzi, kodwa zikwabonisa ukuguquguquka okuchanekileyo koyilo lobugcisa, ukubonelela ngokhetho olutsha lokuphucula izixhobo zezikhululo zombane wamanzi. Njengomenzi we-valve onamava angama-20 eminyaka, i-Jinbin Valve inenkxaso enamandla yobugcisa kwaye inikezela ngezona zisombululo ezinokwethenjelwa ngokusekelwe kwiimfuno zabathengi. Ukuba unayo nayiphi na imibuzo enxulumeneyo, nceda uqhagamshelane nathi ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24! (Ixabiso leValve yeSango lesilayidi)
