ASME Globe Valve
Valve ea Globe ea ASME ke eng?
Li-valve tsa globe ke li-valve tse koalang ka motsamao o otlolohileng tse sebelisetsoang ho qala, ho emisa kapa ho laola phallo ho sebelisoa setho sa ho koala se bitsoang disc. Setulo sa valve ea globe se bohareng ba 'me se bapile le phaephe, 'me lesoba setulong le koetsoe ka disc kapa plug. Disc ea valve ea globe e ka koala tsela ea phallo ka botlalo kapa ea tlosoa ka botlalo. Lesoba la setulo le fetoha ka ho lekana le leeto la disc e leng se loketseng mesebetsi e amanang le taolo ea phallo. Li-valve tsa globe li loketse haholo 'me li sebelisoa haholo ho laola kapa ho emisa phallo ea metsi kapa khase ka phaepheng bakeng sa ho thiba le ho laola phallo ea metsi 'me hangata li sebelisoa liphaepheng tse nyane.
ASME Globe valveke e 'ngoe ea meralo e tsebahalang haholo ea li-valve tsa lefats'e, bakeng sa sistimi ea US le API. bophara ba kahare, thepa, sefahleho le sefahleho, botenya ba lebota, mocheso oa khatello, li hlalosoa ke ASME B16.34.
Ho phaella moo, ho latela moralo oa setulo le diski, mojaro oa litulo oaLi-valve tsa lefats'e tsa ASMEe ka laoloa ka tsela e ntle ke kutu e kurufetsoeng. Bokgoni ba ho kwala bavalvu ea lefats'e ea ASMEe phahame haholo. Li ka sebelisoa bakeng sa mosebetsi oa ho tima. Ka lebaka la sebaka se sekhutšoanyane sa ho tsamaea sa disc pakeng tsa libaka tse bulehileng le tse koetsoeng,Li-valve tsa lefats'e tsa ASMEli loketse haeba valve e lokela ho buloa le ho koaloa khafetsa. Kahoo, li-valve tsa globe li ka sebelisoa bakeng sa mesebetsi e mengata.
eLi-valve tsa Globe tsa ASMEe ka sebelisoa bakeng sa merero ea ho thiba. Mekhahlelo e mengata ea li-valve tse lutseng motho a le mong e sebelisa kaho ea sekhoa kapa ea setaele sa ho boloka selikalikoe sa setulo, e fana ka tataiso ea polaka ea li-valve, le ho fana ka mokhoa oa ho theha litšobotsi tse itseng tsa phallo ea li-valve. E ka boela ea fetoloa habonolo ka ho fetola likarolo tsa trim ho fetola tšobotsi ea phallo kapa ho fana ka bokhoni bo fokotsehileng.phallo, ho fokotsa lerata, kapa ho fokotsa kapa ho felisa cavitation.
Mehlala ea 'Mele ea Li-valve tsa Globe tsa ASME, ho na le mekhoa e meraro ea mantlha ea 'mele kapa meralo ea li-valve tsa Globe, e leng:
- 1).Mohlala o Tloaelehileng (o tsejoang hape e le Mohlala oa Tee kapa T - Mohlala kapa Z - Mohlala)
- 2). Mohlala oa Angle
- 3). Setshwantsho sa Oblique (se tsejoang hape e le Setshwantsho sa Wye kapa Setshwantsho sa Y)
Molao-motheo oa ho Sebetsa oaASME Globe Valve
Valve ea lefats'e e entsoe ka diski e tsamaeang le setulo sa lesale se sa sisinyeheng 'meleng o chitja. Setulo sa valve ea lefats'e se bohareng ba phaephe 'me se bapile le eona, 'me lesoba la setulo le koaloa ka diski. Ha lebili la letsoho le potoloha ka letsoho kapa ka actuator, motsamao oa diski o laoloa (o theotsoe kapa o phahamisitsoe) ka kutu ea valve. Ha diski ea valve ea lefats'e e lutse holim'a lesale la setulo, phallo e emisoa ka ho feletseng.

- 1) .Bokhoni bo botle ba ho tiisa
- 2). Sebaka se sekhutšoanyane sa ho tsamaea sa disk (stroke) pakeng tsa maemo a bulehileng le a koetsoeng,Li-valve tsa lefats'e tsa ASMEli loketse haeba valve e lokela ho buloa le ho koaloa khafetsa;
- 3).Valve ea globe ea ASME e ka sebelisoa e le valve ea ho thibela ho emisoa ka ho fetola moralo hanyane.
- 4).TMona ke mefuta e mengata ea bokhoni bo fumanehang ka mekhoa ea tee, Wye, le angle body.
