Ngokwezimo ezihlukene zohlelo lokusebenza kanye nezidingo, izimpawu ze-valve zepompo zingahlukaniswa zibe izinhlobo eziningi, ikakhulukazi ezihlanganisa: uphawu lwemishini, uphawu lokupakisha, uphawu lwegesi kanye ne-liquid seal.Uhlobo ngalunye lwe-seal lunezici zalo ezihlukile kanye nobubanzi bohlelo lokusebenza.
I-1, uphawu lomshini: uphawu lomshini luwuphawu oluvamile lwe-valve yepompo, lunokunemba okuphezulu, amandla aphezulu, ukumelana nokugqoka okuphezulu kanye nezinye izinzuzo, ezifanele ukujikeleza ngesivinini esikhulu kanye nezikhathi zokuvala ukucindezela okukhulu.Isigxivizo sikamshini sithatha ukwakheka kokupheya kokungqubuzana kweringi okuguquguqukayo nokumile, futhi ubuso bokugcina bendandatho eguquguqukayo ne-static buhambisana nomunye nomunye futhi bunokungqubuzana okuslayidayo okuhlobene, okungafinyelela umphumela wokuvuza uziro.Izigxivizo zemishini zinempilo ende yesevisi kanye nezindleko eziphansi zokulondoloza.
I-2, uphawu lokupakisha: uphawu lokupakisha luwuphawu olulula lwe-valve yepompo, lunezinzuzo zesakhiwo esilula, ukugcinwa okulula, kufanelekile ukucindezela komkhathi noma izikhathi zokuvala ingcindezi ephansi.Isigxivizo sokupakisha senziwe ngezinto zokupakisha ezithambile, njenge-asbestos fiber, i-graphite, njll., ezicindezelwe futhi zixhunywe ngokuqinile ezingxenyeni zangaphakathi zepompo noma i-valve ukuze kuzuzwe umphumela wokuvala.Intengo yokupakisha uphawu ishibhile, futhi ifanele ezinye izimo zesicelo esinezidingo eziphansi.
I-3, uphawu lwe-gas seal liquid seal: uphawu lwe-gas seal liquid seal luyi-valve ye-valve ekhethekile, ingavimbela ukuvuza kwegesi noma imidiya ye-liquid.I-liquid seal yamukela umklamo okhethekile wesakhiwo, ongagcina ingcindezi yegesi noma i-liquid medium ngaphakathi kwebanga elithile, ukuze kuzuzwe umphumela wokuvala.I-Gas seal liquid seal ifaneleka kwezinye izimo zohlelo olukhethekile ezifana nezimo ezivuthayo neziqhumayo, ezinobuthi neziyingozi.
