Zombini iivalvu zokujonga kunye neevalvu zebhola zizixhobo ezibalulekileyo zokulawula ukuhamba kwamanzi. Nangona kunjalo, xa ukhetha ezi valve, ukusetyenziswa kwazo kunye nokufaneleka kwazo kufuneka kuqwalaselwe. Nazi ezinye zezona zinto ziphambili umahluko phakathi kweevalvu zokujonga kunye neevalvu zebhola:
Jonga iivalvu eziveliswe yifektri yaseTshayina eNSW
Iivalvu zebhola eziveliswe ngumzi-mveliso waseTshayina eNSW
1. Amandla okulawula ukuhamba kwamanzi: Iivalvu zokujonga zisetyenziswa kakhulu ukuthintela ulwelo ukuba lungabuyeli kwicala elichaseneyo. Zinokulawula ngokufanelekileyo ukuhamba kwamanzi ngendlela enye, kodwa azinakulawula ukuhamba kwamanzi ngendlela ezimbini. Ngokwahlukileyo koko,iivalvu zebholainokugeleza kwicala elichaseneyo kwaye ibe namandla okulawula ukuhamba kwamanzi ngcono.
2. Imiba yokufaneleka:Jonga iivalvuzidla ngokusetyenziswa kwiindawo ezinoxinzelelo oluphezulu, ezishushu kakhulu okanye ezisebenzisa amanzi amaninzi. Oku kungenxa yokuba uyilo lwazo lunokuthintela ulwelo ukuba lungabuyeli umva kwaye lugcine uxinzelelo luzinzile. Iivalvu zebhola zihlala zisetyenziswa kwiindawo ezinoxinzelelo oluphantsi ukuya koluphakathi kunye nobushushu. Uyilo lwazo lunokuhlangabezana neemeko ezahlukeneyo zokusetyenziswa kunye neemfuno zenkqubo ezahlukeneyo.
3. Ukulahleka koxinzelelo: Iivalvu zokujonga zibangela ukulahleka koxinzelelo oluthile kuba kufuneka zakhe uxinzelelo oluphezulu kwelinye icala ukuthintela ulwelo ukuba lungabuyeli umva. Ngokwahlukileyo koko, iivalvu zebhola zilahlekelwa kancinci kuxinzelelo kuba uyilo lwazo luvumela ulwelo ukuba ludlule ngokumelana okuphantsi.
4. Iimfuno zolondolozo: Iivalvu zokujonga zihlala zifuna ukulungiswa rhoqo kuba zineendawo ezigugayo ukuze zihlale zisebenza. Ezi ndawo zifuna ukutshintshwa nokugcinwa rhoqo. Kwelinye icala, iivalvu zebhola zihlala zifuna ukulungiswa kancinci kuba izinto zazo zangaphakathi zilula kwaye kulula ukuzilungisa.
Lilonke, iivalvu zokujonga kunye neevalvu zebhola zahlukile kubuchule bokulawula ukuhamba kwamanzi kunye nokufaneleka kwawo. Ukuze ukhethe ivalvu efanelekileyo kwisicelo sakho, kufuneka uqwalasele iimfuno zakho ezithile kunye neemfuno zenkqubo.
