4. Arola ho ea ka foromo ea phahamiso

(1) Valve e ikemetseng ha se matla a kantle a ho khothaletsa, empa ka matla a seaplane ka boeona ho etsa boemo ba valve ea valve. Tse kang valve, valve e laolang khatello, sefi sa mouoane, valve ea ho hlahloba, valve ea ho laola othomathike joalo-joalo.

(2) Valve ea ho laola matla a ho khanna: valve ea ho laola matla a ho khanna e ka sebelisa lisebelisoa tse sa tšoaneng tsa matla ho khothalletsa.

Motlakase oa ho laola valve: o itšetlehile ka boenjiniere ba matla ho ntšetsa pele valve.

Pneumatic valve: valve e tsamaisoang ke khatello ea moea.

Hydraulic valve: valve e tsamaisoang ke khatello ea metsi a kang oli.

Ho phaella moo, ho boetse ho na le likarolo tsa lihlopha tse ka holimo tsa mekhoa ea ho khanna, tse kang li-valve tse laolang motlakase oa khase.

(3) Motlakase oa letsoho: valve ea tataiso e itšetlehile ka spindle, rocker, rod bar, sprocket chain, ka lisebelisoa tsa batho ho laola boemo ba valve. Ha valve e bula le ho koala torque e batlang e le kholo, lebili kapa sesebelisoa sa "worm gear" se ka beoa lipakeng tsa spindle le setulo. Haeba ho hlokahala, manonyeletso a cardan le li-shafts tse potolohang li ka boela tsa sebelisoa bakeng sa ts'ebetso e sebetsang ea nako e telele.

5, ho latela sehlopha sa bophara ba bophara ba lebitso

(1) Belofo e nyane ea bophara: valve ea "diameter" e bitsoang DN¡Ü40mm valve.

(2) Belofo ea bophara bo bohareng: phunya ka lebitso la DN ea 50 ~ 300mm valve.

(3) Belofo e kholo ea bophara: valve ea bophara ba lebitso la DN ea 350 ~ 1200mm valve.

(4) Belofo e fetang boholo: belofo e nang le bophara ba lebitso DN¡Ý1400mm.

6. Arola ho latela mofuta oa sebopeho

(2) Belofo ea ho hokahanya e nang le flanged: 'mele oa valve o na le poleiti ea flange, e hokahaneng le flange ea lipeipi.

(3) valve ea khokahano ea welding ea motlakase: 'mele oa valve o na le seam oa welding oa motlakase, le khokahano ea phala ea welding.

(4) Valofo ea ho hokela: 'mele oa li-valve o na le thipa 'me o hokahane le phala.

(5) Mofuta oa letsoho o kopanyang valve: e nang le khetho ea phala ea khokahanyo e kopanetsoeng ea mofuta oa sleeve.

(6) Valfo ea ho hokela: mokhoa oa ho hokela oo valve le liphaephe mahlakoreng ka bobeli li tlamelloang hammoho hang-hang ka boutu ea fatše.

8, ho latela lisebelisoa tsa 'mele oa valve

(1) Metal valve: 'mele oa valve le likarolo tse ling li entsoe ka thepa ea tšepe. Tse kang valve ea tšepe ea kolobe, valve ea tšepe ea carbon, valve ea tšepe ea alloy, alloy copper valve, aluminium alloy profile valve, aluminium alloy valve, titanium valve, Monel alloy valve, joalo-joalo.

(2) valve e se nang tšepe: 'mele oa valve le likarolo tse ling li entsoe ka thepa e seng ea tšepe. Tse kang valve ea polasetiki, valve ea ceramic, valve e nang le lined, FRP anticorrosive valve, joalo-joalo.

(3) lisebelisoa tsa tšepe tse nang le valve ea 'mele: moralo oa ponahalo ea li-valve bakeng sa thepa ea tšepe, sebopeho sa ka hare moo ho kopana le seaplane haholo-holo ka holim'a lesela, joalo ka mochine oa oli, valve ea polasetiki, valve ea ceramic, joalo-joalo.

Ea bobeli, katleho ea valve ea semela sa lik'hemik'hale

Mofuta o bulehileng le o koalehileng: khaola kapa ho buisana le metsi a metsi a pipe ea ac;

Ho fetola mofuta: fetola sekhahla sa phallo eohle le lebelo la phallo ka tube;

Mofuta oa valve ea throttle: etsa mokelikeli ho latela valve ka mor'a ho baka khatello e kholo haholo ea khase;

Mefuta e meng: a. ka ho feletseng ho bula le ho koala ka ho feletseng B. ho boloka khatello e itseng ea ho sebetsa C. mouoane o thibelang phala ea drainage.
