I-DN80 uphawu lokuvalwa kwethangi le-vacuum

I-DN80I-valve entantayoIhlanganisa ibhola elintantayo, ingxenye yokushayela, kanye nokulawula i-plug elawulwa yi-plug yenaliti ye-hydraulic amplification. I-piston isebenzisa uhlelo lokuhlubuka kwengcindezi, futhi ingaphezulu lokubekwa uphawu lendawo ephezulu likhulu kunale ndawo engezansi. Amafutha okucindezela avela emthonjeni wokunikezwa kwamafutha angena emgodini ophakathi we-piston bese engena emgodini ongaphezulu wepiston. I-vent phakathi kwepiston elawulwa yi-plug yenaliti ixhumeke ngethangi lamafutha. Lapho izinga loketshezi lethangi lamafutha lijwayelekile, i-buoyancy yebhola elintantayo idluliswa nge-lever futhi lenyuke, ukuze enze ikhanda le-conical le-plug yenaliti licindezelwe ngokuqinile ku-vent phakathi kwe-piston. Ngokucindezela okubangelwa umthombo wamafutha wokucindezela ukungena emthonjeni ongaphezulu wepiston indawo engenhla ye-piston inkulu kakhulu kunendawo kawoyela ye-seal. I-piston esebenzayo ihamba yaya phansi futhi icindezelwa ngokuqinile endaweni ebeka uphawu. I-valve igcinwa ivaliwe.
I-buoyancy yebhola elintantayo liyancipha kanye nezinga eliwuketshezi lwamaconsi kawoyela. Lapho amandla afanele akhulu kunamandla akwesobunxele adalwe yi-buoyancy yebhola lokusungula, ipulaki yenaliti lisuka kwesokudla bese kuvulwa indawo ephakathi nendawo yepistoni. Amafutha engcindezelo engxenyeni engenhla ye-piston akhishwe ithangi lamafutha e-vacuum, futhi uwoyela emgodini ophakathi wePiston uphoqelela i-piston ngakwesokunene futhi uvula i-valve ukuze unikeze uwoyela wethangi lamafutha. Lapho izinga le-ketshezi liphuma lisesimweni esithile, i-buoyancy yebhola elintantayo lenyuka futhi iphuzu lenaliti ye-valve licindezelwa ngokuqinile emgodini wesikhungo. I-cavity engenhla ye-piston ixhumene nomthombo kawoyela wokucindezela. Le khasiisivalwanakuvaliwe futhi kuqedwa ukunikezwa uwoyela. Inqubo yokulethwa uwoyela ihambisana nokushintshwa kwezinga eliwuketshezi kancane. I-plug yenaliti kanye nepiston kuhamba ngasikhathi sinye. Isimiso sokusebenza sifana ne-valve ye-oyili ukuze ulawule izinga lethangi lamafutha.
