Isikhokelo kunye nokuFumaneka kweValve yeSango le-intshi ezingama-36: Umboneleli woBukhulu be-NSW

I-Mighty Flow Controller: Isikhokelo Sakho Esipheleleyo SeeValve Zesango Eziyi-36 Inch

Kwihlabathi lolawulo lolwelo lwemizi-mveliso, apho imibhobho ifana neendlela ezinkulu zolwelo kunye neegesi,Iivalvu zeSango ezingama-36 intshizimi njengabalindi ababalulekileyo. Ezi valve zinkulu zenzelwe usetyenziso olufuna amandla okuhamba kwamanzi aphezulu, ukuvalwa okuthembekileyo, kunye nokusebenza okuqinileyo phantsi kweemeko ezinzima. Zifumaneka ekuveliseni umbane, ekucoceni amanzi, ekudluliseleni ioyile negesi, emigodini, nasekucutshungulweni kweekhemikhali okukhulu, ukukhetha okulungileyo.I-Valve yeSango engama-36kubandakanya ukuqonda iinkcukacha ezibalulekileyo. Esi sikhokelo sijonga nzulu kwizinto ezisetyenziswayo, ukulinganiswa koxinzelelo, iintlobo zonxibelelwano, kunye nemeko-bume yazo.Abavelisi beValve yeSango le-intshi ezingama-36.

Ukuqonda Isikali: Kutheni i-36 intshi ibalulekile

Ubungakanani obupheleleyo beIvalvu yeSango le-intshi ezingama-36(ubungakanani bombhobho oqhelekileyo – NPS 36, ububanzi bangaphandle bokwenyani ~ 914mm) bubonisa indima yayo kwimigca yothumelo oluphambili, iindawo eziphambili zokungenisa/zokukhupha, kunye neenkqubo zokudlula kwiindawo ezinkulu.Iivalvu zeSango ezinkuluEzi zithwala umthamo omkhulu, nto leyo eyenza ukuthembeka kwazo kube yeyona nto ibalulekileyo. Ukungaphumeleli akusiyo nje into yokuvuza; kunokuthetha ixesha lokungasebenzi kakuhle, umngcipheko kwindalo, kunye nokulungiswa okubiza kakhulu. Ukukhetha ivalvu echanekileyo kubandakanya ukuqwalaselwa ngononophelo kwezinto ezahlukeneyo.

1. Umqolo: Izinto zokwakha iiValve zeSango ezingama-36 intshi

Ukukhethwa kwezinto kubalulekile, kuxhomekeka kulwelo, ubushushu, uxinzelelo, kunye neemeko zokusingqongileyo (ezifana nokukwazi ukugqwala). Izinto eziqhelekileyo ziquka:
