Valv Globe Steel Cast: Kontwolè Flow serye pou aplikasyon pou presyon ki wo

Nan sistèm tiyo endistriyèl yo, valv la glòb asye jete kanpe soti kòm yon aparèy gaya ak serye pou reglemante koule likid, patikilyèman ekselan nan gwo presyon ak anviwònman gwo tanperati. Konstriksyon solid li yo ak kapasite sele egzak fè li endispansab nan aplikasyon pou kritik ki enplike vapè, lwil oliv, ak dlo presyon-wo.

Estrikti a nan yon valv glòb asye jete se Enjenieri pou durability ak fèmen sere. Li konsiste de yon kò vale asye jete (tipikman te fè soti nan materyèl tankou WCB oswa WC6, li te ye pou fòs yo ak rezistans nan korozyon), yon disk, yon tij valv, yon handwheel, ak eleman chèz. Kò an asye jete asire valv la ka kenbe tèt ak presyon k ap travay sòti nan 1.6MPa 10MPA ak tanperati ki soti nan -29 ℃ 425 ℃, fè li apwopriye pou kondisyon endistriyèl piman bouk. Disk la ak chèz prezante yon presizyon-machined plat oswa koòdone konik, ki fèt yo fòme yon sele sere lè se valv la fèmen.
Prensip la opere depann sou mouvman lineyè kontwole koule. Wotasyon handwheel la kondwi tij valv la, ki deplase disk la axially nan direksyon oswa lwen chèz la. Lè disk la desann byen sere anfòm kont chèz la, valv la fèmen, konplètman bloke koule nan likid. Ogmante disk la kreye yon diferans annulèr ant disk la ak chèz la, sa ki pèmèt likid pase nan -ak gwosè a diferans reglabl kontwole pousantaj koule. Sa a aksyon "etalaj" pèmèt valv la pa sèlman fèmen koule antyèman, men tou nivo koule amann-melodi, fè li ideyal pou aplikasyon pou ki mande kontwòl egzak.
Valv glòb asye jete jwenn itilize toupatou nan jenerasyon pouvwa (egzanp, kontwole vapè surchofe nan plant pouvwa tèmik), petwòl raffinage (reglemante lwil bit ak pwodwi rafine), ak sistèm rezèv dlo-wo presyon. Avantaj kle yo gen ladan yo:
  • Pèfòmans eksepsyonèl sele : anfòm ki sere ant disk la ak chèz asire zero fwit, kritik pou anpeche pèt medya ki gen danje ladan oswa ki gen anpil valè.
  • Segondè presyon ak rezistans tanperati : konstriksyon an asye jete kenbe entegrite estriktirèl nan kondisyon ekstrèm.
  • Adaptabilite nan kontwòl koule : Kapab nan tou de sou/sou fèmen ak trennen, adapte a divès bezwen operasyonèl.
  • Fasilite nan antretyen : eleman entèrchanjabl tankou disk ak chèz senplifye reparasyon, pwolonje lavi sèvis valv la.
Pandan ke konsepsyon yo kreye pi wo rezistans koule konpare ak tiyo pòtay, tiyo glòb asye jete konpanse ak presizyon kontwòl siperyè. Iterasyon modèn, tankou sa yo ki gen tij soufle-sele, plis amelyore sere fwit, satisfè sevè estanda sekirite endistriyèl. Kòm yon poto nan sistèm likid endistriyèl, valv la glòb asye jete kontinye jwe yon wòl enpòtan anpil nan asire transpò likid ki an sekirite, efikas, ak kontwole atravè sektè kritik.
