Isifundo: Ukusetyenziswa ngempumelelo kweevalvu zeglowubhu yombane kwiiprojekthi ezinkulu zemizi-mveliso
1,Intshayelelo
Iivalvu zeglowubhu yeflange zombane zidlala indima ebalulekileyo kwiiprojekthi zemizi-mveliso emikhulu. Badlala indima ebalulekileyo kulawulo lolwelo kunye nenkqubo yokuzenzela. Eli nqaku liza kuphonononga nzulu ukusetyenziswa kweevalvu zeglowubhu yombane kwiiprojekthi ezinkulu zemizi-mveliso ngokusebenzisa isifundo esithile, kunye nendlela yokuqinisekisa ukusebenza kwabo ngempumelelo kunye nokuthembeka kwexesha elide.
2,Imvelaphi yeprojekthi
Kwiprojekthi yepetrochemical enkulu, kufuneka kwakhiwe inkqubo yokuthutha ulwelo oluntsonkothileyo kunye nenkqubo yokulawula ukuze kuqinisekiswe inkqubela phambili egudileyo yenkqubo yokuvelisa. Kule projekthi, i-valve ye-globe ye-flange yombane yakhethwa njengesixhobo sokulawula ulwelo oluphambili, onoxanduva lokulawula ngokuchanekileyo izinga lokuhamba kunye noxinzelelo oluphakathi kwizigaba ezahlukeneyo zokuvelisa.
3,Inkqubo yokukhetha iivalvu zeglowubhu yeflange yombane
1. Uhlalutyo lwendlela yokusebenza
Iqela leprojekthi liqale liqhube uhlalutyo olunzulu lwendlela yokusebenza, kubandakanywa ukubunjwa kweekhemikhali, ubushushu, uxinzelelo kunye nezinye iiparamitha. Ezi ziqwenga zolwazi zibalulekile ekukhetheni izixhobo zomzimba zevalvu ezifanelekileyo, amatywina, kunye neendlela zokuqhuba.
2. Uvavanyo lwemeko yokusingqongileyo
Ukuqwalasela iimeko zokusingqongileyo zendawo yeprojekthi, ezifana nokutshintsha kweqondo lokushisa, ukufuma, ukubola, njl.
3. Iinkcukacha zobugcisa kunye neemfuno zokusebenza
Ngokweemfuno zoyilo lobunjineli, iqela leprojekthi lidwelise iinkcukacha zobugcisa kunye neemfuno zentsebenzo ye-valve yeglobhu ye-flange yombane, kubandakanywa i-diameter yegama, uxinzelelo lwegama, ukusebenza kokutywinwa, ubomi benkonzo, njl. Ezi parameters ziye zaba sisiseko esiphambili sokukhethwa.
4. Uvandlakanyo lwababoneleli
Xa ukhetha ababoneleli, iqela leprojekthi liqwalasela ngokubanzi imiba efana negama lomthengisi, amandla obugcisa, umgangatho wemveliso, kunye nenkonzo emva kokuthengisa. Ekugqibeleni, sikhethe umthengisi onegama elihle kwishishini.
4,Ukusetyenziswa okuyimpumelelo kweevalvu zeglowubhu yeflange yombane
Ngethuba lenkqubo yokuphunyezwa kweprojekthi, i-valve ye-globe ye-flange yombane ifakwe kwiindawo eziphambili zokulawula, ezijongene nokulawula ngokuchanekileyo ukuhamba kunye noxinzelelo lwe-medium. Ngovavanyo oluqinileyo kunye nokuguqulwa, ukusebenza kwevalve kuye kwaqinisekiswa ukuhlangabezana neemfuno zoyilo.
5,Iziphumo zeProjekthi kunye nesiShwankathelo
Emva kwexesha lokusebenza, ivalve yeglowubhu yeflange yombane iqhube kakuhle kule projekthi, iqinisekisa ngokufanelekileyo inkqubela phambili yenkqubo yokuvelisa. Ukusebenza kwabo ngokufanelekileyo kunye nokuthembeka kwexesha elide kuye kwaqatshelwa liqela leprojekthi.
Ngale meko, sinokubona ukuba kwiiprojekthi ezinkulu zemizi-mveliso, ukhetho oluchanekileyo kunye nokusetyenziswa kweevalve zeglobhu yombane ngundoqo ekuqinisekiseni ukusebenza okuqhelekileyo kweenkqubo zokulawula ulwelo. Iqela leprojekthi kufuneka liqhube ukhetho lwesayensi kunye nolawulo olungqongqo lolwakhiwo olusekelwe ekuqondeni ngokucokisekileyo indawo yokusebenza, iimeko zokusingqongileyo, kunye neemfuno zobugcisa. Kungale ndlela kuphela esinokuthi siqinisekise impumelelo yeevalvu zeglowubhu yeflange yombane kwizicelo ezibonakalayo.
