Iivalvu zeglowubhu ziyinxalenye ebalulekileyo yemizi-mveliso emininzi

Izivalo zeglowubhu ziyinxalenye ebalulekileyo yemizi-mveliso emininzi, ebonelela ngolawulo oluchanekileyo lolwelo olukwimibhobho nakwiinkqubo. Ezi valves zinezinto ezininzi kwaye zinokusetyenziswa kwiintlobo ezahlukeneyo zezicelo, zizenza ukhetho oludumileyo phakathi kweenjineli kunye nabayili benkqubo.

Enye yeenzuzo eziphambili zeevalvu zeglowubhu kukukwazi kwabo ukulawula ukuhamba kolwelo ngokuchaneka okuphezulu. Oku kufezekiswa ngokusebenzisa i-disc ekhutshwayo enokuthi ibekwe ukulawula ukuhamba nge-valve. Ke ngoko, iivalvu zeglowubhu zihlala zisetyenziswa apho kufuneka ulawulo oluchanekileyo lokuhamba kolwelo, olufana nezityalo zokucocwa kwamanzi, izixhobo zokulungisa imichiza, kunye nezixhobo zombane.

Ukongeza kubuchule bazo bolawulo oluchanekileyo, iivalvu zeglowubhu zikwayaziwa ngokuqina nokuthembeka kwazo. Ezi zivalo zenzelwe ukumelana noxinzelelo oluphezulu kunye namaqondo obushushu, zizenze zilungele ukusetyenziswa kwiindawo zoshishino ezinzima. Kananjalo azikho lula ukuvuza kunezinye iindidi zeevalvu, ezibonelela ngokhuseleko olukhulu kwiinkqubo ezifakwe kuzo.

Iivalvu zeglowubhu zifumaneka ngokobukhulu obahlukeneyo kunye nemathiriyeli, ezenza zilungele usetyenziso olwahlukeneyo. Zingenziwa kwizinto ezifana nensimbi engenasici, i-carbon steel kunye ne-bronze kwaye iyahambelana neentlobo ezahlukeneyo zamanzi kunye neemeko zokusebenza. Ukongeza, iivalvu zeglowubhu zinokuyilwa ngeendidi ezahlukeneyo zokudityaniswa kwesiphelo, ezinje ngeflanged, intambo, okanye i-welded, ukuze ihambelane neemfuno ezithile zenkqubo enikiweyo.

Ngokumalunga noyilo, ivalve yeglowubhu ibonakala ngokumila komzimba ongqukuva, kungoko igama layo. Olu luyilo luvumela ukuhamba ngendlela ehamba kakuhle ngevalve, ukunciphisa uxinzelelo kunye nesiphithiphithi kwinkqubo. I-disc ngaphakathi kwevalve ngokuqhelekileyo ikhokelwa yi-valve stem, enokuthi yenziwe ngesandla, ngombane okanye i-pneumatic actuated ukulawula ukuhamba kwamanzi. Olu luyilo luvumela ukusebenza okuchanekileyo kunye nokuthembekileyo kwe-valve, ukuqinisekisa ukuba izinga lokuhamba elifunekayo lihlala ligcinwa.

Iivalvu zeglowubhu ziqhele ukufakwa kwiinkqubo apho ulwelo lungena ukusuka ezantsi luze luphume lusuka phezulu. Olu lungelelwaniso luvumela i-valve ukuba isetyenziswe njengesixhobo sokutshiza, ukulawula izinga lokuhamba ngokulungelelanisa indawo yediski. Kwezinye iimeko, iivalve zeglobhu zinokufakwa kwakhona kwi-counter-flow configuration, kunye ne-flow flow engena phezulu kwaye iphuma ezantsi, kuxhomekeke kwiimfuno ezithile zenkqubo.

Isishwankathelo, iivalvu zeglowubhu zizinto ezibalulekileyo kwiinkqubo ezininzi zoshishino, ezivumela ulawulo oluchanekileyo lokuhamba kwamanzi kunye nokusebenza okuthembekileyo kwiindawo ezinzima. Ngenxa yokuguquguquka kwazo, ukuqina kunye neendlela ezahlukeneyo zokhetho, iivalvu zeglowubhu lukhetho oludumileyo phakathi kweenjineli kunye nabayili benkqubo abafuna ukuqinisekisa ukusebenza ngokufanelekileyo, ngokukhuselekileyo kweenkqubo zabo. Ingaba isetyenziselwa unyango lwamanzi, ukusetyenzwa kweekhemikhali, ukuveliswa kwamandla okanye ezinye izicelo, iivalvu zeglowubhu zibonelela ngenqanaba lolawulo kunye nokuthembeka okubalulekileyo kwimpumelelo yeenkqubo zanamhlanje zoshishino.
