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 oaBS1873 valve ea lefats'e
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.
