Eshabhu lokukhiqiza le-Jinbin Valve Co., Ltd., inkampani kagesi enkulu kakhuluivalvu yesangoiqede ukuhlolwa kokugcina kokusebenza kokuvula nokuvala. Le valve yesango inokuphakama okuphelele okungamamitha angu-8.3 kanye nobubanzi obujwayelekile be-DN2400. Zonke izilinganiso kanye nezinkomba zokusebenza zevalvu yesango zihlangabezane nezindinganiso, futhi sezizolethwa kumakhasimende ukuze zisetshenziswe kuphrojekthi.

I-valve yesango likagesi i-DN2400 evivinywe kulokhu kuhlolwa iwumkhiqizo owenziwe ngokwezifiso wekhasimende, ofanelekela amaphrojekthi amakhulu okuthuthwa koketshezi embonini yokugcina amanzi, kamasipala, kanye nekagesi. Iyimishini eyinhloko yezinhlelo zamapayipi amakhulu. Uma iqhathaniswa nama-valve avamile, le valve enkulu yesango inkulu ngobukhulu, iyinkimbinkimbi iyaqhubeka nokusebenza, futhi inezindinganiso zokukhiqiza eziphakeme kakhulu zokunemba kokusatshalaliswa, amandla esakhiwo, ukusebenza kokuvala, kanye nokuqina kokulawula kagesi. Umzimba we-valve wenziwe ngensimbi eqinile ye-alloy, emelana nengcindezi, ukuguguleka, kanye nokugqwala, futhi ingashintshwa ukuze ivumelane nezimo zokusebenza zangaphandle nezimboni eziyinkimbinkimbi nezinzima. Inempilo ende yenkonzo kanye nokuqina.

Ivalvu ifakwe i-actuator kagesi ehlakaniphile esebenza kahle kakhulu, enekhono elinamandla lokukhipha i-torque, ukusebenza kokuvula nokuvala okubushelelezi, ukwesekwa kokulawula okuzenzakalelayo okukude kanye nokusebenza kwendawo ngesandla, kanye nemisebenzi eminingi yokuphepha efana nomkhawulo wokuhamba, ukuvikelwa kokulayisha ngokweqile, kanye nempendulo yesimo sesikhathi sangempela. Inezinga eliphezulu lokuvikela, igwema ngempumelelo ukwehluleka kokusebenza kwemishini futhi iqinisekise ukusebenza okuphephile nokuzinzile kohlelo lwamapayipi.

Ngesikhathi senqubo yokuhlola, ochwepheshe balandele ngokuqinile amazinga futhi benza izivivinyo eziphelele neziqinile mayelana nokuguquguquka kokuvulwa nokuvalwa kwe-valve, ukusebenza kokuvala, ukunemba kokulawula kagesi, kanye nokuzinza kokusebenza okujikelezayo kokusebenza okuyinhloko. Ngemva kokuhlolwa okulandelanayo komjikelezo wokuvula nokuvala, imishini yasebenza kahle ngaphandle kokujima, futhi zonke izinkomba zokusebenza zahlangabezana nezidingo zamaphrojekthi amakhulu abalulekile.

Ngemva kweminyaka eminingi yokuzibandakanya ngokujulile embonini yokukhiqiza ama-valve, i-Jinbin Valve igxile ocwaningweni nasekukhiqizweni kwama-valve amakhulu nalawo angewona ajwayelekile, njengama-valve esango, amasango e-penstock, ama-valve esango ashelelayo, ama-valve egesi yomoya, nama-valve epuleti elivaliwe. Ithembele ezinqubweni zokukhiqiza ezivuthiwe, imishini yokuhlola ukukhiqiza ethuthukisiwe, kanye nohlelo oluphelele lokulawula ikhwalithi, ihlinzeka njalo ngemishini yokulawula uketshezi esezingeni eliphezulu yamaphrojekthi amakhulu obunjiniyela basekhaya nakwamanye amazwe, iqhubeka nokukhombisa izinzuzo zekhwalithi eyinhloko kanye nensizakalo yokwenza ngokwezifiso yomkhiqizi womthombo wama-valve.
