Iindaba zeShishini

Isizathu sokuba kutheni iivalvu zebhola zinokuvula ngokukhawuleza kunye nokuvalwa kulele kubume bazo obukhethekileyo bomatshini kunye noyilo lwamandla olwelo.

Kukho iimfuno ezithile ezahlukeneyo zokufakelwa kweevalve zebhola ukuqinisekisa ukusebenza kwazo okuqhelekileyo kunye nokusetyenziswa kwexesha elide.

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
