Ivalufa yeSango leNsimbi engenaStainless

Inxalenye yokuvula kunye nokuvala i-valve yesango yensimbi engenasici yisango, kwaye isalathiso sokuhamba kwesango si-perpendicular ukuya kwicala le-fluid. Isango lensimbi engenasici lineendawo ezimbini zokutywina. Imiphezulu emibini yokutywina yevalve yesango esetyenziswa kakhulu yenza i-wedge, kwaye i-engile ye-wedge iyahluka ngokweeparamitha zevalvu. Isango levalve yesango le-wedge linokwenziwa liphelele, elibizwa ngokuba lisango eliqinileyo; ingenziwa kwakhona kwisango elinokuvelisa i-deformation encinci yokuphucula ukwenziwa kwayo kunye nokuhlawulela ukuphambuka kwe-angle yokutywinwa komhlaba ngexesha lokucubungula. Ipleyiti ibizwa ngokuba yisango elastiki. Izinto zevalvu yesango yentsimbi engenasici zahlulwe zibe yiCF8, CF8M, CF3, CF3M, 904L, Duplex Stainless Steel (4A, 5A, 6A).
Iindidi zeevalvu zesango zensimbi engenasici zinokwahlulwa ngokweevalve zesango ezinqamlezileyo kunye neevalvu zesango ezinxuseneyo ngokobume bomphezulu wokutywina. Iivalve zesango le-Wedge zinokuhlulwa zibe: uhlobo lwesango elilodwa, uhlobo lwesango eliphindwe kabini kunye nohlobo lwesango eli-elastic; I-valve yohlobo lwesango elihambelanayo Inokwahlulwa ibe luhlobo olulodwa lwesango kunye nohlobo lwesango eliphindwe kabini. Yahlulwe ngokwendawo yomsonto wesiqu sevalve, inokohlulwa ibe ziindidi ezimbini: ivalve yesango evulekileyo nevalve yesango elimnyama. Olu hlobo lwevalve kufuneka lufakwe ngokubanzi ngokuthe tye kumbhobho.
Xa i-valve ivuliwe, xa ukuphakama kokuphakama kwesango kufana ne-1: 1 amaxesha ububanzi be-valve, i-fluid passage ayivaliwe ngokupheleleyo, kodwa esi sikhundla asikwazi ukubeka iliso ngexesha lokusebenza. Ekusetyenzisweni kwangempela, i-apex ye-valve stem isetyenziswe njengophawu, oko kukuthi, indawo apho ayikwazi ukuvulwa, njengendawo yayo evulekile ngokupheleleyo. Ukuze kuthathelwe ingqalelo isenzeko sokutshixa ngenxa yokutshintsha kweqondo lobushushu, ivalve idla ngokuvulelwa kwi-apex position kwaye emva koko ibuyiselwe umva nge-1/2 ukuya ku-1 ukujika njengendawo evuleke ngokupheleleyo. Ngoko ke, indawo evulekile ngokupheleleyo yevalve inqunywe yindawo yesango (okt stroke).
Kwezinye iivalve zesango, i-stem nut ibekwe kwisango, kwaye ukujikeleza kwe-handwheel kuqhuba ukujikeleza kwe-valve stem ukuphakamisa isango. Olu hlobo lwevalve lubizwa ngokuba yivalve yesango yesiqu esijikelezayo okanye ivelufa yesango elimnyama.
