Njengoko umthamo wokuhamba uyancipha, umlinganiselo ohlengahlengiswayo wevalve uya kuncipha. Kodwa noko inokuqinisekiswa ukuba iphakathi kwe-10:l kunye ne-15:1. Ukuba umlinganiselo ohlengahlengiswayo uncinci, kuya kuba nzima ukulungelelanisa ukuhamba.
Xa iivalve zisetyenziselwa uchungechunge, kunye nokutshintsha kokuvula, umahluko woxinzelelo phakathi kwangaphambili nangasemva kweevalvu nawo uyatshintsha, nto leyo eyenza ukuba ijika elibonisa ukusebenza kweevalvu liphambuke kwiimpawu ezifanelekileyo. Ukuba ukuchasana kombhobho kukhulu, umgca womgca uya kuba ngumqondiso wokuvula ngokukhawuleza, kwaye amandla okulungelelaniswa aya kulahleka. Iimpawu zepesenti ezilinganayo ziya kuba ziimpawu zomgca othe ngqo. Ngaphantsi kwemeko yesantya esincinci sokuhamba, ngenxa yokuba kuncinci ukuchasana kwemibhobho, ukuphazamiseka kwezi mpawu zingentla akukukhulu, kwaye ipesenti elinganayo impawu ayidingekile. Ukususela kumbono wokuvelisa, xa i-Cv = 0.05 okanye ngaphantsi, akunakwenzeka ukuvelisa ipesenti elinganayo yeemilo zecala. Ngoko ke, ingxaki ephambili yee-valve ezincinci yindlela yokulawula ukuhamba phakathi koluhlu olufunekayo.
Ngokombono wempembelelo yezoqoqosho, abasebenzisi banethemba lokuba ivalve ingasetyenziselwa zombini ukungenelela kunye nokulawula, kwaye inokwenziwa. Kodwa kwivalve yokulawula, ikakhulu ukulawula ukuhamba, kwaye ukuvala kukwesibini. Akulunganga ukucinga ukuba ukuhamba kwevalve encinci ngokwayo kuncinci kakhulu kwaye kulula ukuqaphela ukungenelela xa ivaliwe. Ukuvuza kweevalvu ezincinci zokulawula ukuhamba kulawulwa ngokubanzi ngaphandle. Xa ixabiso leCv liyi-10, ukuvuza kwevalve kuchazwa njenge-3.5 kg / cm. Ngaphantsi koxinzelelo lomoya, ukuvuza kungaphantsi kwe-1% yokuhamba okuphezulu.
