Lithini Ixesha Lokuvula Nokuvala kweGlobe Valve

Ixesha lokuvula nelokuvala kweivalvu yeglobhulixesha elithathwa yidiski yevalvu ukusuka ekuvalekeni ngokupheleleyo ukuya ekuvulekeni ngokupheleleyo, okanye ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo. Ngenxa yokuba ivalvu yeglobe isebenzisa isiqu esinyukayo esithe nkqo kunye nevili lesandla elijika-jikayo okanye i-actuator, ixesha layo lokusebenza lidla ngokuba lide kuneevalvu ezifana neevalvu zebhola okanye iivalvu zebhabhathane.

Ixesha Eliqhelekileyo Lokuvula Nokuvala

①Ivalvu yeGlobe yesandla

• Ubungakanani obuncinci (DN15–DN50):
  Imizuzwana emi-5–12ngokujikeleza okuqhelekileyo kwevili lesandla.

• Ubungakanani obuphakathi (DN65–DN150):
  Imizuzwana eli-10–25kuxhomekeke ekuhambeni kwesiqu kunye namandla omqhubi.

• Ubukhulu obukhulu (DN200–DN350 nangaphezulu):
  Imizuzwana engama-25–60 nangaphezulu, kuba zifuna ukujika amaxesha amaninzi ukuze zihambise idiski.

②Ivalvu yeGlobe eSebenzayo yoMbane

• Uninzi lwee-actuators zombane zisebenza ngaphakathi kwezi:
  Imizuzwana engama-20–60 (isantya esiqhelekileyo)
  Ii-actuator ezikhawulezayo zingathatha ukuya kuthi ga kwimizuzwana eli-120 ukuba iivalvu ezinkulu ziphephe ihamile yamanzi.

③Ivalvu yeGlobe eSebenzayo yoMoya

• Ikhawuleza kunezombane kodwa icotha kunezivali zokuvula/zokuvala.
  Uluhlu oluqhelekileyo: imizuzwana emi-3–20, kuxhomekeke kubonelelo lomoya kunye nobukhulu be-actuator.

Kutheni iiGlobe Valve zithatha ixesha elide ukusebenza

• ①Isiqu kufuneka sihambe umgama omde ukuze silawule ukuhamba kwamanzi ngokuchanekileyo.

• ②Ivili lesandla lifuna ukujikajika izihlandlo ezininzi ukuze kuthintelwe utshintsho olukhawulezileyo loxinzelelo.

• ③Uyilo lwevalvu lubeka phambili ulawulo lokuhamba kwamanzi kunye nokuchaneka endaweni yokucima ngokukhawuleza.

• ④Ukusebenza kancinci kunceda ekunciphiseni ihamile yamanzi, ingakumbi kwiinkqubo zaselwandle nakwiindawo zoshishino.

Izinto Ezichaphazela Ixesha Lokusebenza

• ①Ubungakanani bevalvu kunye novavanyo loxinzelelo

• ②Iphimbo lomsonto wesiqu (imisonto emincinci = intshukumo ecothayo)

• ③Uhlobo lwe-actuator (ngesandla, ngombane, ngomoya, nge-hydraulic)

• ④Uxinzelelo lwenkqubo

• ⑤Ukungqubana okanye ukuguguleka ngaphakathi kwevalvu

• ⑥Useto lweTorque okanye isantya kwii-actuators

Kwizicelo zaselwandle, ukuvala kancinci kusetyenziswa ngabom ukukhusela iinkqubo zamanzi olwandle, imigca ye-ballast, kunye neenkqubo zokupholisa ekunyukeni koxinzelelo ngequbuliso.
