Iindaba zeShishini

Ukufakelwa kweevalve zebhabhathane kufuneka zilandele ngqo imigaqo-nkqubo yokusebenza, kwaye i-Mesticaightuiko lanyanzelwa ukusuka ekulungiselelekeni kwangoko kulungiselelo kunye nokugunyazisa.

Iivallo zebhabhathane, njengoko i-valves eqhelekileyo esetyenziswa kwiinkqubo zokulawula i-fluid, inokuchaphazela ukusebenza okuqhelekileyo kwale nkqubo yonke kwimeko yokuvuza kwamanzi. Apha ngezantsi kukho intshayelelo kwizizathu kunye nezisombululo zebhabhathane le-valve.

Ukukhetha ivalve enebhabhathane ethembekileyo kuqwalaselwa ngokuthathelwa ingqalelo kwesakhiwo, isixhobo, kunye neemeko zokusebenza.

Kwimimandla yemveliso yezamashishini kunye nolawulo lwamanzi, i-valves yebhabhathane zezona zixhobo ziphambili, kwaye ukhetho oluchanekileyo ludlala indima ethatha isigqibo malunga nokusetyenziswa kwenkqubo. Nje ukuba ivalve yebhabhathane ikhethwe ngokungachanekanga, iya kubangela uthotho lweengxaki ezinkulu.

Iivalves zebhola zisetyenziswa ngokubanzi kwimizi-mveliso kunye nendawo yoluntu, kodwa zihlala zibandezeleka ngenxa yezizathu ezilandelayo

Njengesixhobo esiphambili kwicandelo lolawulo lwamanzi, ukusebenza kwebhola kwi-valves ibalulekile. Nje ukuba intsebenzo yokutywina kwe-valve yebhola ihlwempuzekile, ayizukubangela kuphela ukuvuza okuphakathi kwaye kuchaphazele ukhuseleko lwemveliso, kodwa kukukhokelela kwinkunkuma yezixhobo kunye nongcoliseko lwendalo. Ke, singayicombulula njani ingxaki yokutywina kakubi kweevalves zebhola?
