Kwihlabathi leentshukumo zolwelo kunye neenkqubo zokufaka imibhobho, iivalvu zokukhangela zidlala indima ebalulekileyo ekuqinisekiseni ukuhamba kakuhle nangokukhuselekileyo kolwelo kunye neegesi. Njengenxalenye ebalulekileyo kwiintlobo ngeentlobo zezicelo zoshishino, ukuqonda ukuba yintoni ivalvu yokukhangela, iintlobo zayo kunye nabavelisi banokunceda iinjineli kunye neengcali zokuthenga ukuba benze izigqibo ezinolwazi. Eli nqaku liza kujonga ubunzima beevalvu zokukhangela, ligxile kwiintlobo zazo, imisebenzi kunye nabavelisi abaphambili beevalvu zokukhangela, ngakumbi eTshayina.
Ukuqonda iiValvu zokujonga
Ivalvu yokukhangela, eyaziwa ngokuba yivalvu yendlela enye, sisixhobo soomatshini esivumela ulwelo ukuba luhambe kwicala elinye ngelixa luthintela ukubuya kwamanzi. Oku kubalulekile kwizicelo ezininzi, ezifana neenkqubo zokubonelela ngamanzi, unyango lwamanzi amdaka, kunye neenkqubo ezahlukeneyo zoshishino. Umsebenzi ophambili wevalvu yokukhangela kukukhusela izixhobo kunye nokugcina ukuthembeka kwenkqubo ngokuthintela ukuhamba okungasemva, okunokubangela ungcoliseko, umonakalo wezixhobo, okanye ukusilela kwenkqubo.
Umgaqo wokusebenza weValve yokujonga
Umgaqo osebenzayo wevalvu yokujonga kukusebenzisa umahluko woxinzelelo phakathi komsinga ophezulu nowezantsi. Xa uxinzelelo olukwicala lokungena ludlula uxinzelelo olukwicala lokukhupha, ivalvu iya kuvula ize ivumele ulwelo ukuba ludlule. Ngokwahlukileyo koko, ukuba uxinzelelo olukwicala lokukhupha luya lukhula, ivalvu iya kuvala ize ithintele ukubuya kwamanzi. Le ndlela ilula kodwa isebenzayo yenza ivalvu yokujonga ingabi yimfuneko kwiinkqubo ezininzi.
Iintlobo zeeValve zokuHlola
Kukho iintlobo ezininzi zeevalvu zokujonga, nganye yenzelwe ukusetyenziswa okuthile kunye neemeko zokuhamba kwamanzi. Ezona ntlobo zixhaphakileyo ziquka:
1. Ivalvu yokujonga iSwing
Ivalvu yokujonga ukujika yenye yezona ntlobo zisetyenziswa kakhulu. Inediski ejikajika kwihinji, ivumela ulwelo ukuba luhambe kwicala elinye ngelixa luvala ukuba kuvela ukubuya kwamanzi. Iivalvu zokujonga ukujika zilungele ukusetyenziswa kokuhamba kwamanzi okuphantsi ukuya kophakathi kwaye zisetyenziswa kakhulu kwiinkqubo zamanzi, kwiinkqubo ze-HVAC, nakwiinkqubo ezahlukeneyo zoshishino.
2. Ivalvu yokujonga iipleyiti ezimbini
Ivalvu yokujonga idiski ephindwe kabini ineepleyiti ezimbini ezijikeleza kwi-axis efanayo. Olu yilo luvumela ivalvu encinci nekhaphukhaphu xa ithelekiswa nevalvu yokujonga iswing eqhelekileyo. Iivalvu zokujonga idiski ephindwe kabini zisebenza kakuhle kakhulu kwizicelo ezihamba kakhulu kwaye zisetyenziswa kakhulu kwimibhobho, kwizityalo zonyango lwamanzi, nakwishishini leoyile negesi.
3. Ivalvu yokujonga intsimbi engatyiwayo
Iivalvu zokujonga intsimbi engagqwali zenzelwe ukusetyenziswa okufuna ukumelana nokugqwala nokuqina. Ezi valve zisetyenziswa kakhulu ekucubunguleni iikhemikhali, kumashishini okutya neziselo, nakwiindawo zokusebenzisa ulwandle. Ukwakhiwa kwentsimbi engagqwali kuqinisekisa ubomi benkonzo ende kunye nokuthembeka okuphezulu, nto leyo eyenza ukuba ibe lukhetho olukhethwayo ziinjineli ezininzi.
Ukubaluleka Kokukhetha Umenzi Wevalvu Yokujonga Efanelekileyo
