Iivalve ezijikelezayo ziyinxalenye ebalulekileyo kwizicelo ezininzi zamashishini. Idlala indima ebalulekileyo ekulawuleni icala lokuqukuqela kolwelo, ukuqinisekisa ukusebenza kakuhle, nokuthintela iingozi ezinokubakho. Nangona kunjalo, kukho izilumkiso ezithile ezifunekayo ukuba ziqwalaselwe xa usebenzisa i-valve ye-reverse flow ukuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide.

Okokuqala, kubalulekile ukuqonda ukuba i-valve ejikelezayo isebenza njani. Le valve ivumela ulwelo ukuba luqukuqele kwicala elinye ngelixa lukhusela umva. Iqukethe idiski eshukumayo okanye i-flap evula xa ulwelo luhamba ngendlela oyifunayo kwaye luvale xa ulwelo luhamba kwelinye icala. Ukuqonda lo matshini kubalulekile kufakelo olululo kunye nokusebenza kweevalvu ezibuyela umva.

 Isilumkiso esibalulekileyo kukukhetha uhlobo oluchanekileyo kunye nobukhulu bevalve yokubuyela umva kwisicelo. Iivalvu kufuneka zilungele iimpawu zolwelo ezifana noxinzelelo, ubushushu kunye ne-viscosity. Ukusebenzisa ivalve engafanelekanga kunokubangela ukuvuza, ukunciphisa ukusebenza kakuhle, kunye nomonakalo onokwenzeka kwisixhobo sakho.

Ukugcinwa rhoqo kubalulekile ukuqinisekisa ukusebenza ngokufanelekileyo kwevalve ejikelezayo. Ukuhlolwa rhoqo kunye nokucoca kuyimfuneko ukukhusela nayiphi na i-blockage okanye i-debris buildup enokuthi ichaphazele ukusebenza kwevalve. Ukongeza, ukuthanjiswa kwamalungu ashukumayo kunye nokutshintshwa kwezitywina ezigugileyo kunye neegaskets zibalulekile ekuthinteleni ukuvuza kunye nokwandisa ubomi bevalve.

Esinye isilumkiso xa usebenzisa i-valve ejikelezayo kukuqinisekisa ukufakela ngokufanelekileyo. Kufuneka ifakwe kwindawo ekulula ukuyigcina nokulungisa. Ivalve kufuneka ilungelelaniswe ngokufanelekileyo kunye nombhobho ukuthintela nakuphi na ukuvuza okanye ukuguga okugqithisileyo kumalungu evalve.

Ukongezelela, kubalulekile ukuhlola rhoqo iivalve ngeempawu zokuguga okanye ukonakala. Naziphi na izinto ezingaqhelekanga, ezinjengomhlwa, iintanda, okanye iindawo ezixengayo, kufuneka zilungiswe ngokukhawuleza. Ukulungiswa ngokukhawuleza kunye nokutshintshwa kubalulekile ekuthinteleni ukonakala okukhulu kunye nokulungiswa okuxabisa kakhulu.

Isishwankathelo, iivalve ezijikelezayo ziyinxalenye ebalulekileyo kwizicelo ezininzi zamashishini. Ngokuthatha izilumkiso eziyimfuneko, ezifana nokukhetha okufanelekileyo, ukugcinwa rhoqo, kunye nokufakwa ngokufanelekileyo, i-valve ye-reverse flow valve inokuqinisekisa ukusebenza ngokufanelekileyo, ukukhusela ubungozi obunokwenzeka, kunye nokwandisa ubomi bayo benkonzo. La manyathelo okhuseleko kufuneka aqondwe kwaye aphunyezwe ukugcina indawo yokusebenza ethembekileyo nekhuselekileyo.
