(1) Ama-valve okwakhiwa kwedolobha: ama-valve anengcindezi ephansi ngokuvamile asetshenziswa ezinhlelweni zokwakha zasemadolobheni, futhi okwamanje asathuthuka ngendlela yokuvikela imvelo nokonga amandla.

Amavalvu epuleti lerabha anobungani bemvelo, amavalvu ebhalansi, amavalvu ovemvane aphakathi nendawo, namavalve uvemvane avalwe ngensimbi ashintsha kancane kancane amavalvu esango lensimbi elinengcindezi ephansi.Iningi lama-valve asetshenziswa ezakhiweni zasemadolobheni ezifuywayo ama-balance valves, ama-valve esango avaliwe, ama-butterfly valves, njll.

(2) Amavalvu okushisa asemadolobheni: inqwaba yamavalvu evemvane evalwe ngensimbi, amavalvu ebhalansi avundlile kanye namavalvu amabhola agqitshwe ngokuqondile ayadingeka ohlelweni lokushisa lwasemadolobheni.Lawa ma-valve axazulula inkinga yokungalingani kwe-hydraulic eqondile nevundlile yepayipi, azuze ukonga amandla, futhi anciphise ukukhiqizwa kokushisa.umgomo we.

(3) Amavalvu egesi yedolobha: Igesi yedolobha yenza u-22% wayo yonke imakethe yegesi yemvelo, futhi inani lamavalvu likhulu futhi kunezinhlobo eziningi.Ikakhulu idinga i-valve yebhola, i-plug valve, i-valve yokunciphisa ingcindezi, i-valve yokuphepha.

(4) Amavalvu amapayipi ahamba amabanga amade: amapayipi ahamba amabanga amade ikakhulukazi uwoyela ongahluziwe, imikhiqizo eqediwe namapayipi emvelo.Amavalvu adingwa iningi lala mapayipi amavalvu ensimbi enziwe mbumbulu aneziqephu ezintathu ezigcwele amabhola, amavalvu esango eliyisicaba elivikela isibabule, amavalvu okuphepha, namavalvu okuhlola.

(5) Amavalvu okuvikela imvelo: Uhlelo lokuphakelwa kwamanzi ohlelweni lokuvikela imvelo yasekhaya ludinga ikakhulukazi ukusebenzisa ivalve uvemvane oluphakathi nendawo, ivalve yesango evalwe ngokuthambile, ivalve yebhola, kanye ne-exhaust valve (yomile ukuze ikhiphe umoya epayipini, futhi uhlelo lokuhlanza indle ngokuyinhloko ludinga ukusebenzisa i-valve uvemvane evalwe ngokuthambile kanye ne-butterfly valve.
