ASME Globe Valve
ASME Globe Valve ke eng?
Li-valve tsa globe ke li-valve tse koalang fatše tse sebelisoang ho qala, ho emisa kapa ho laola phallo ho sebelisa setho sa ho koala se bitsoang disc.Setulo sa valve ea globe se bohareng ba 'me se tsamaisana le phala,' me sebaka sa setulo se koetsoe ka disc kapa plug. The globe valve disc e ka koala ka ho feletseng tsela ea phallo kapa e ka tlosoa ka ho feletseng.Sebaka sa ho bula setulo se fetoha ka ho lekana le leeto la disc le loketseng mesebetsi e amanang le taolo ea phallo.Li-valve tsa globe li loketse haholo 'me li sebelisoa haholo ho laola kapa ho emisa ho phalla ha mokelikeli kapa khase ka phala bakeng sa ho phunya le ho laola phallo ea mokelikeli 'me hangata li sebelisoa liphaepheng tse nyane tsa boholo.
ASME Globe valveke e 'ngoe ea tse ratoang ka ho fetisisa moralo oa li-valve tsa globe, bakeng sa US le tsamaiso ea API. bophara ba ka hare, lisebelisoa, sefahleho le sefahleho, botenya ba lebota, mocheso oa khatello, li hlalosoa ke ASME B16.34.
Ho phaella moo, ho itšetlehile ka moralo oa setulo le disc, mojaro oa litulo oaLi-valve tsa ASME tsa lefats'ee ka laoloa hantle ka kutu e sehiloeng.Bokhoni ba tiiso eaASME valve ea lefats'ee phahame haholo.Li ka sebelisoa bakeng sa mosebetsi oa ho tlohela mosebetsiLi-valve tsa ASME tsa lefats'eli loketse haeba valve e tlameha ho buloa le ho koaloa khafetsa.Kahoo, li-valve tsa lefats'e li ka sebelisoa bakeng sa mesebetsi e mengata e fapaneng.

ASME Globe Valve Body Patterns, ho na le mekhoa e meraro ea mantlha ea 'mele kapa meralo ea li-valve tsa Globe, e leng:
- 1).Standard Pattern (eo hape e tsejoang e le Tee Pattern kapa T - Pattern kapa Z - Pattern)
- 2).Angle Pattern
- 3).Oblique Pattern (eo hape e tsejoang e le Wye Pattern kapa Y - Pattern)
Molao-motheo oa ho sebetsa oaASME Globe Valve
Valofo ea globe e entsoe ka disc e suthehang le setulo sa selikalikoe se emeng 'meleng o chitja.Setulo sa valve ea globe se bohareng ba 'me se bapile le phala,' me lesoba la setulo le koetsoe ka disc.ha lebili la letsoho le potoloha ka letsoho kapa ka actuator, motsamao oa disc o laoloa (o theoleloa kapa o phahamisitsoe) ka sekhahla sa valve.Ha "globe valve disc" e lutse holim'a selikalikoe sa setulo, phallo e emisoa ka botlalo.
