Iindaba zeShishini

Ukulungiswa kweengxaki zee-valve zokutshekisha kufuneka zidibaniswe kunye neentlobo eziqhelekileyo zeempazamo kwaye zihlalutywe ngokuchanekileyo inyathelo ngesinyathelo.

Njengesixhobo esiphambili sokuthintela umva ophakathi, iivalve zokujonga zisetyenziswa ngokubanzi kwiinkqubo zemibhobho.

Jonga ivalve, ebizwa ngokuba yiValve yeHowve okanye ivalve enye, yinto ebalulekileyo kwiinkqubo zokulawula. Eyona njongo iphambili kukuthintela ukubuyela umva kwe-hidflow, qinisekisa ukuhamba ngendlela enye yokuhamba, ukukhusela izixhobo, kunye nokugcina ukusebenza kwezinzile.

Ukukhethwa kwamasango eendawo zesango ngamaqondo obushushu aphantsi kufuneka kuthathwe ngqo kwimiba emithathu: ukuqina kwezinto, ukusebenza, kunye noyilo lwesakhiwo

I-vilves yesango isetyenziswa ngokubanzi kwimizi-mveliso kunye neyabantu, kodwa ngexesha lokusetyenziswa, bahlala befumana ukuqaqanjelwa, okuchaphazela ukusebenza kwesiqhelo kwenkqubo

Njengevalve eqhelekileyo esetyenziselwa ukuvala ivalve, ukuba ukutywinwa kwe-valve yesango akuqinanga, kuya kubangela iingxaki ezinjengokuvuza okuphakathi, okuya kuchaphazela ukusebenza kwesiqhelo kwenkqubo.
