Indlela yokufaka iivalvu zebhola ixhomekeke ngokungqongqo kuhlobo lwazo kunye neempawu zoyilo. Uninzi lweevalvu zebhola eziqhelekileyo azinazithintelo zendlela, kodwa iintlobo ezikhethekileyo zifuna ukuthotyelwa ngokungqongqo kwisikhokelo esibonakalisiweyo sofakelo.

Iivalvu zokukhangela zinokuthintela ngokufanelekileyo ukuguqulwa kwempompo. Umgaqo ongundoqo kukuxhomekeka kumahluko woxinzelelo lwe-fluid ukuze ufezekise ukuqhutywa kwendlela enye kunye ne-reverse cutoff.

Njengesixhobo esiphambili sokuthintela ukubuya umva okuphakathi, iivalvu zokutshekisha zisetyenziswa kakhulu kwimizi-mveliso, kuluntu nakwimimandla ekhethekileyo. Umsebenzi wabo ophambili kukukhusela ukhuseleko lwezixhobo, ukugcina uzinzo lwenkqubo, kunye nokuphepha iingozi.

Ngaba ivalve yokutshekisha ayinakuwamisa amanzi? Ezi ndlela ziya kukunceda ukusombulula

Iivalvu zokujonga ziimveliso zolawulo lwamanzi eziyimfuneko kushishino lwangoku kwaye ngoku zezinye zezona ntlobo zisetyenziswa kakhulu zeevalvu.

Kukho iintlobo ezine zeevalvu zokutshekisha: ukuphakamisa kunye nokulahla, ukujinga, ibhola kunye nepleyiti
