Zombini iivalve zokutshekisha kunye neevalve zebhola zizixhobo ezibalulekileyo zokulawula ukuhamba. Nangona kunjalo, xa ukhetha ezi zivalo, ukusetyenziswa kwazo kunye nokufaneleka kwazo kufuneka kuthathelwe ingqalelo. Nazi ezinye zeeyantlukwano eziphambili phakathi kweevalvu zokutshekisha kunye neevalvu zebhola:
Khangela iivalvu eziveliswe ngumzi-mveliso waseTshayina i-NSW
Iivalvu zebhola eziveliswe ngumzi-mveliso waseChina iNSW
1. Izakhono zokulawula ukuqukuqela: Iivalvu zokujonga zisetyenziswa ikakhulu ukuthintela ulwelo ukuba lungabuyeli ngasemva kwelinye icala. Banokulawula ngokufanelekileyo ukuhamba kwendlela enye, kodwa abakwazi ukulawula ukuhamba ngeendlela ezimbini. Okuchasene,iivalve zebholainokuqukuqela kwicala elahlukileyo kwaye ibe namandla okulawula ukuqukuqela okungcono.
2. Imiba yokufaneleka:Khangela iivalvuzidla ngokusetyenziswa kwi-high-pressure, high-temperature okanye kwi-high-flow applications. Oku kungenxa yokuba uyilo lwabo lunokuthintela ulwelo ukuba lungabuyeli ngasemva kwaye lugcine uxinzelelo luzinzile. Iivalvu zebhola zidla ngokusetyenziswa kuxinzelelo oluphantsi ukuya oluphakathi kunye nezicelo zobushushu. Uyilo lwabo lunokuhlangabezana neentlobo ezahlukeneyo zeemeko zesicelo kunye neemfuno ezahlukeneyo zenkqubo.
3. Ukulahleka koxinzelelo: Iivalve zokujonga zibangela umlinganiselo othile welahleko yoxinzelelo ngenxa yokuba zifuna ukwakha uxinzelelo oluphezulu kwicala elinye ukuthintela ulwelo ukuba lungabuyeli ngasemva. Ngokwahlukileyo, iivalve zebhola zinelahleko encinci yoxinzelelo kuba uyilo lwazo luvumela ulwelo ukuba ludlule ngokuxhathisa okuphantsi.
4. Iimfuno zogcino: Iivalvu zokutshekisha zidla ngokufuna ukulungiswa rhoqo kuba zineendawo ezigugayo ukuze zihlale zisebenza. La malungu afuna ukutshintshwa kunye nokugcinwa rhoqo ngamaxesha amaninzi. Ngakolunye uhlangothi, iivalve zebhola zifuna ukulungiswa okuncinci ngenxa yokuba izinto zazo zangaphakathi zilula kwaye kulula ukuzigcina.
Ngokubanzi, ii-valve zokutshekisha kunye neevalve zebhola ziyahluka kwizakhono zokulawula ukuhamba kunye nokufaneleka. Ukukhetha eyona valve ilungileyo kwisicelo sakho, kufuneka uqwalasele iimfuno zakho ezithile kunye neemfuno zenkqubo.
