Zombini ii-valves zokujonga kunye neevalves zebhola zizinto ezibalulekileyo zolawulo lokuhamba. Nangona kunjalo, xa ukhetha ezi valve, ukusetyenziswa kwawo kunye nokulungele kufuneka kuthathelwe ingqalelo. Nanga ezinye zomahluko ophambili phakathi kweevalves zokujonga kunye neevalva zeBhola:
Jonga i-valves eveliswa nguMzi-mveliso wase-China NSW
I-valves yebhola eveliswa nguMzi-mveliso wase-China NSW
I-1. Izakhono zoLawulo lokuhamba: Jonga i-valves esetyenziselwa ukuthintela ukunqanda ulwelo ukuba luhambele kwelinye icala. Banokulawula ngokuphumelela indlela enye, kodwa abakwazi ukulawula ukuhambahamba ngeendlela ezimbini. Okuchasene,I-valves yebholainokuhamba kwelinye icala kwaye inezakhono zokulawula ukuhamba okuqhumayo.
2. Imiba efanelekileyo:Jonga i-valveveszihlala zisetyenziswa kuxinzelelo oluphezulu, ubushushu obuphezulu okanye izicelo eziphezulu zokuhamba. Kungenxa yokuba uyilo lwawo luthintela amanzi ukuba abuye kwaye agcine uxinzelelo oluzinzileyo. Iivalves zebhola zihlala zisetyenziswa kuxinzelelo oluphakathi kunye nokusetyenziswa kweqondo lobushushu. Uyilo lwabo lunokuhlangabezana neemeko ezahlukeneyo zesicelo kunye neemfuno ezahlukeneyo zeenkqubo.
3. Uxinzelelo Ukuphulukana Ngokwahlukileyo, i-valve yebhola ineelahleko ezingenamsebenzi kuba uyilo luvumela amanzi ukuba agqithe ngokuchasene nezantsi.
4. Iimfuno zolondolozo: Jonga i-valves zihlala zifuna ulondolozo rhoqo kuba zinamacandelo anokuhlala esebenza kakuhle. La macandelo afuna ukutshintshwa kunye nolondolozo ngamaxesha amaninzi. Kwelinye icala, i-valves yebhola zifuna ukohlwaywa okuncinci kuba izinto zabo zangaphakathi zilula kwaye zilula ukuyigcina.
Ngokubanzi, valves kunye neeValves kunye neeValds zahlukile kubuchule bokulawula ukuhamba kunye nokufaneleka. Ukukhetha i-valve efanelekileyo yesicelo sakho, kuya kufuneka uqwalasele iimfuno zakho kunye neemfuno zenkqubo.
