4. Phatlalatso: e sebelisetsoang ho fetola phallo ea mahareng, mokhoa oa ho aba, joalo ka mokoko oa litsela tse tharo, valve ea ho aba, valve ea slide, joalo-joalo.
5 Valve ea polokeho: ha khatello e mahareng e feta boleng bo boletsoeng, e sebelisoa ho ntša sebaka se feteletseng ho netefatsa polokeho ea lipeipi le lisebelisoa, joalo ka valve ea polokeho le valve ea kotsi.
6.Litšebeliso tse ling tse khethehileng: tse kang valve ea sefi, valve ea moea, valve ea likhoerekhoere, joalo-joalo.
7.Four, ho latela mokhoa oa ho khanna, ho latela mokhoa o fapaneng oa ho khanna o ka aroloa:
1. Bukana: ka thuso ea lebili la letsoho, molamu, lever kapa sprocket, joalo-joalo, ka koloi ea motho, khanna mochine o moholo oa torque oa sebōkō, lisebelisoa le lisebelisoa tse ling tsa deceleration.
2. Motlakase: o tsamaisoa ke enjene kapa sesebelisoa se seng sa motlakase.
3. Hydraulic: Ho khanna ka thuso ea (metsi, oli).
4. Pneumatic: e tsamaisoa ke moea o hatelitsoeng.
Tse hlano, ho ea ka khatello, ho ea ka khatello ea lebitso la valve e ka aroloa:
1. Vacuum valve: khatello e feletseng < Li-valve tse nang le bolelele ba 0.1mpa, kapa 760mm hg, hangata li bontšoa ke mm hg kapa mm kholomo ea metsi.
2. Valofo e tlaase ea khatello: khatello ea lebitso PN≤ 1.6mpa valve (ho akarelletsa le PN≤ 1.6mpa valve ea tšepe)
3. Belofo ea khatello e bohareng: khatello ea lebitso PN2.5-6.4mpa valve.
4. Valofo e phahameng ea khatello: khatello ea lebitso PN10.0-80.0mpa valve.
5. Belofo e phahameng ea khatello e phahameng: khatello ea lebitso PN≥ 100.0mpa valve.
Tse tšeletseng, ho ea ka mocheso oa seaplane, ho ea ka valve sebetsa seaplane mocheso o ka aroloa:
1. Belofo e tloaelehileng: e loketse mocheso o mahareng -40 ℃ ~ 425 ℃ valve.
2. Belofo e phahameng ea mocheso: e loketse mocheso o bohareng oa 425 ℃ ~ 600 ℃ valve.
3. Belofo e thibelang mocheso: e loketse mocheso o mahareng ka holimo ho 600 ℃ valve.
4. Belofo e tlaase ea mocheso: e loketse mocheso o bohareng -150 ℃ ~ -40 ℃ valve.
5. Valofo ea mocheso o tlase haholo: e loketse mocheso o mahareng o ka tlase ho -150 ℃ valve.
Tse supileng, ho ea ka bophara ba lebitso, ho ea ka bophara ba "valve" bo ka aroloa:
1. Sephahla se senyenyane sa bophara: sekhahla sa lebitso la DN<40mm valve.
2. Belofo ea bophara bo bohareng: valve ea bophara ba lebitso la DN50 ~ 300mm valve.
3. Sephahla se seholo sa bophara: sekhahla sa lebitso la DN350 ~ 1200mm valve.
4. Belofo ea bophara ba boholo bo feteletseng: phunya ka lebitso la DN≥1400mm valve.
Viii.E ka aroloa ho ea ka mokhoa oa ho hokahanya ha valve le pipeline:
1. Belofo e nang le flanged: 'mele oa valve o nang le flanged, le phaephe e nang le belofo.
2. Valofo ea khoele e nang le khoele: 'mele oa valve o nang le khoele e ka hare kapa khoele e ka ntle, valve e kopantsoeng le pipeline.
3. Belofo ea khokahano e cheselitsoeng: 'mele oa li-valve o nang le li-welds, le liphaephe tse nang le li-valve tse cheselitsoeng.
4. Belofo ea ho hokela: 'mele oa li-valve o nang le seqhomane, le valafo ea ho hokela phala.
5. Sephahla sa ho hokahanya ka letsoho: valve e kopantsoe le sleeve le pipeline.
