Umehluko phakathi kokufakwa uphawu okuthambile nokufaka uphawu okunzima umi kanje:

1. Umehluko wesakhiwo kanye nendlela

Ngokuvamile, uphawu oluqinile lwe-valve yebhola lusho uphawu oluphakathi kwensimbi nensimbi, kanti indawo yokuvala kanye nesihlalo sevalvu kokubili kuyinsimbi.Uphawu oluthambile lusho ukuthi izindawo ezimbili ezithintanayo zokuvala zingasetshenziswa zodwa noma zonke izinto ezithambile zingasetshenziswa.

2. Umehluko ezintweni zokuvala uphawu

Ngaphansi kwesimo esivamile, ama-valve ebhola avalwe kanzima enziwa ukunemba ngomshini ngokusebenzisa izinto zesihlalo se-valve ukuze kuqinisekiswe ukunemba okuhambisanayo nengqikithi ye-valve (ibhola), ngokuvamile insimbi engagqwali nethusi.Isigxivizo esithambile sisho ukuthi into yokuvala eshumekwe esihlalweni sevalvu yinto engeyona eyensimbi.Ngenxa yokuthi izinto ezithambile zokuvala zinokunwebeka okuthile, izidingo zokunemba kokucubungula ziphansi kunalezo zokuvala okunzima.

3. Umehluko ezimeni zokusetshenziswa

Ngokwezimo zokusetshenziswa, ngokuvamile izimpawu ezithambile zingafinyelela izinga eliphezulu, kuyilapho izimpawu eziqinile zingaba phezulu noma eziphansi ngokuvumelana nezidingo;izimpawu eziqinile ngokuvamile zingenza umfutho omkhulu, kodwa izimvu zamanzi ezithambile azikwazi;izimpawu ezithambile Isigxivizo sidinga ukuvutha umlilo, ngoba ngaphansi kwezinga lokushisa eliphezulu, impahla ye-soft seal izovuza, kuyilapho uphawu oluqinile lungenayo le nkinga;uphawu oluthambile alukwazi ukusetshenziswa kwezinye izikhathi ngenxa yenkinga yendawo egelezayo (njengemithombo yezindaba egqwalayo);Ama-valve avalwe kanzima ngokuvamile abiza kakhulu kunalawo avaliwe.Mayelana nokukhiqiza, kunomehluko omncane phakathi kwalokhu okubili, ikakhulukazi umehluko phakathi kwesihlalo se-valve, uphawu oluthambile aluyona insimbi, futhi uphawu oluqinile luyinsimbi.

4. Umehluko kumazinga okukhiqiza

Ngokombono wesimiso, ama-valve ebhola avaliwe ngokuqinile kanye nama-valve ebhola avaliwe ayafana, kodwa ngenxa yokuthi kuwuphawu phakathi kwezinsimbi, ubudlelwano bokuqina phakathi kwezinsimbi, kanye nezimo zokusebenza, kufanele kucatshangelwe.medium, njll. Ukwelashwa kokuqina ngokuvamile kuyadingeka, futhi ukugaya okuqhubekayo phakathi kwebhola nesihlalo sevalvu kuyadingeka ukuze kuzuzwe ukuvala.Umjikelezo wokukhiqiza wama-valve ebhola avaliwe isikhathi eside, ukucubungula kuyinkimbinkimbi, futhi akulula ukwenza ama-valve ebhola avaliwe kahle.

Uma ungumkhiqizi noma unjiniyela kulezi zimboni ezingenhla futhi unentshisekelo yokufunda okwengeziwe ngezivalo eziqinile noma ama-valve ophawu athambile, sicela.Xhumana nathiukuze uthole izixazululo ezengeziwe.
