Ibisobanuro bigufi:

Valve y'inzira eshatu yo gufungani agace gafunga cyangwa valve izunguruka ifite ishusho ya plunger, izunguruka dogere 90 kugira ngo ikore umuyoboro uri kuri valve plug n'umubiri wa valve by'umwe cyangwa bitandukanye, bifungure cyangwa bifunge valve. Iplagi ya valve plug ishobora kuba ifite imiterere ya cylindrical cyangwa cornical. Mu plagi cycle, imiyoboro muri rusange iba ifite impande enye; Mu plagi ifite tape, umuyoboro ni trapezoidal. Izi shusho zituma imiterere ya valve plug yoroha, ariko icyarimwe igatera igihombo runaka. Valve plug ikwiriye cyane mu gukata no guhuza ibyuma no guhindura imiterere, ariko bitewe n'imiterere y'ikoreshwa n'ubudahangarwa bw'ubuso bwo gufunga, rimwe na rimwe ishobora no gukoreshwa mu gufunga. Kubera ko kugenda hagati y'ubuso bwo gufunga bwa valve plug bigira ingaruka zo guhanagura, kandi iyo ifunguye neza, ishobora gukumira burundu kwegera icyuma gitemba, bityo ishobora no gukoreshwa ku bikoresho bifite uduce duto duhagaze. Ikindi kintu cy'ingenzi cya valve plug ni uko yoroshye guhuza imiterere y'imiyoboro myinshi, ku buryo valve ishobora kugira imiyoboro ibiri, itatu, cyangwa ine itandukanye y'imiyoboro. Ibi byoroshya imiterere y'imiyoboro, bigabanya ikoreshwa rya valve, kandi bigabanya umubare w'ibikoresho bikenewe mu bikoresho.
