insimbi engagqwalii-valve ye-flap eyindilinga

Isango le-flap liyi-valve yendlela eyodwa efakwe lapho kuphuma khona ipayipi lepayipi ukuze kusetshenziswe amanzi kanye nokukhipha amanzi kanye nokuhlanzeka kwendle kuyasebenza. Isetshenziselwa ukuchichima noma ukuhlola okuphakathi, futhi ingasetshenziselwa izembozo ezihlukahlukene ze-shaft. Ngokusho komumo, umnyango oyindilinga kanye nomnyango wokumbambatha wesikwele wakhiwe. Umnyango we-flap ikakhulukazi wakhiwe umzimba we-valve, ikhava ye-valve kanye nengxenye yehinge. Inezinhlobo ezimbili zezinto zokwakha, i-cast iron ne-carbon steel. Amandla ayo okuvula nokuvala avela ekucindezelweni kwamanzi futhi akudingi ukusebenza ngesandla. Ingcindezi yamanzi kumnyango we-flap inkulu kunaleyo engaphandle komnyango we-flap, futhi iyavuleka. Uma kungenjalo, iyavala futhi ifinyelele umphumela wokuchichima kanye nokumisa.
