Indlela yokusebenza
Inqubo yokuvala: Lapho i-valve ivalekile, kwakheka uphawu olunamandla phakathi kwe-half ball nesihlalo, nomthelela wokucindezela kwemidiya wenza indandatho yokuphawula ye-ball nesihlalo zivaleke ndawonye ukuze kuqinisekiswe ukuthi akukho ukuvuza.
Inqubo yokuvula: Lapho kuvulwa, ibhola le-spool lihamba phambili ngendlela elihle esihlalweni, lisuse kahle isithiyo samatshe bese lizuza uphawu oluthembekile. Isakhiwo esiphindwe kabili esiyisikhombisa senza i-spool ibekwe egumbini lebhola lapho ivulwa, umnyango wokugeleza mkhulu, futhi i-valve ayigezi.
Izici nezinzuzo
Ukuzihlanza nokuvimbela ukulimala: Isakhiwo esiyingqayizivele se-double eccentric senza isenzo sokusika phakathi kwe-hemisphere nesihlalo lapho kuvaliwe singasusa isikali nokunamathela ebusweni bokuphawula, futhi sinomthelela wokuthi "izihlanza ngokwayo" nokuthi "ivimbela ukulimala".
Ukusebenza okuphawulekayo kokuphawula: Izinto ezingezona ezensimbi ezinamathiselwe esihlalweni sensimbi, ubuso bensimbi besihlalo se-valve buvikelwe kahle, futhi isibini sokuphawula sisebenzisa indandatho yensimbi enobuso obuqinile bokuthintana ukuze kuqinisekiswe ukusebenza okuphawulekayo okuzinzile isikhathi eside.
Isakhiwo esihlangene: I-valve ye-half ball ye-double eccentric inesakhiwo esilula, usayizi omncane, isisindo esilula, kulula ukuyifaka nokuyigcina.
