Indlela yokusebenza
Inqubo yokuvala: Lapho i-valve ivalekile, kwakheka isitembu esinwebekayo phakathi kwe-half ball nesihlalo, nomthelela wokucindezela kwemidiya wenza indandatho yokubopha ye-ball nesihlalo ziqine ndawonye ukuqinisekisa ukuthi akukho ukuvuza.
Inqubo yokuvula: Lapho kuvulwa, ibhola le-spool lihamba phambili ngendlela elihle esihlalweni, likhipha kahle isithiyo samatshe, futhi liqinisekisa ukubambelela okuthembekile. Isakhiwo esiphindwe kabili esiyisikhungo senza i-spool ibekwe egumbini lebhola lapho ivulwa, ingxenye yokugeleza inkulu, futhi i-valve ayigezi.
Izici nezinzuzo
Ukuzihlanza nokuvimbela ukulimala: Isakhiwo esiyingqayizivele se-double eccentric senza isenzo sokusika phakathi kwe-hemisphere nesihlalo lapho kuvalwa singasusa isikali nokunamathela ebusweni bokubopha, futhi sinomthelela wokuthi "izihlanza ngokwayo" nokuthi "ivimbela ukulimala".
Ukusebenza okuhle kokubopha: Izinto ezingezona ezensimbi ezinwebekayo zifakwe esihlalweni sensimbi, ubuso bensimbi besihlalo se-valve buvikelwe kahle, futhi isibini sokubopha sisebenzisa indandatho yensimbi enobuso obuqinile bokubopha okuthintwayo ukuqinisekisa ukusebenza okuzinzile kokubopha isikhathi eside.
Isakhiwo esihlangene: I-valve ye-half ball ye-double eccentric inesakhiwo esilula, usayizi omncane, isisindo esilula, kulula ukuyifaka nokuyigcina.
