Isingeniso sokusetshenziswa, izinto eziyinhloko kanye nezici zesakhiwo sevalve yokuhlola i-wafer

Hlola i-valve isho i-valve evula ngokuzenzakalelayo futhi ivale i-valve flap ngokuncika ekugelezeni kwe-medium ngokwayo ukuvimbela ukugeleza emuva kwe-medium, eyaziwa nangokuthi.hlola i-valve, i-valve yendlela eyodwa, i-valve yokugeleza ehlehlayo kanye ne-valve yokucindezela emuva. Ihlola i-valveiyi-valve ezenzakalelayo umsebenzi wayo oyinhloko uwukuvimbela ukubuyela emuva kwe-medium, ukuzungezisa okubuyela emuva kwepompo kanye nenjini yokushayela, kanye nokukhipha okuphakathi esitsheni. Amavalvu okuhlola angasetshenziswa emigqeni ehlinzeka ngamasistimu asizayo lapho ukucindezela kungase kukhuphuke ngaphezu kokucindezela kwesistimu.

1.Tusebenzisa i-valve yokuhlola i-wafer:

Ihlola i-valve ifakwe ohlelweni lwamapayipi, futhi umsebenzi wayo oyinhloko ukuvimbela ukubuyela emuva kwe-medium. Ihlola i-valveiyi-valve ezenzakalelayo evulekayo futhi ivalwe kuye ngomfutho ophakathi.I-valve yokuhlola i-wafer ifanele ingcindezi okuzisholo PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; ububanzi okuzisholo DN15~1200mm, NPS1/2~48; Ukubuyela emuva okumaphakathi. Ngokukhetha izinto ezahlukene, ingasetshenziswa emithonjeni ehlukahlukene efana namanzi, umusi, uwoyela, i-nitric acid, i-acetic acid, i-oxidizing medium eqinile kanye ne-uric acid.

2.Tyena impahla main of thei-valve yokuhlola i-wafer:

Kukhona carbon steel, low lokushisa steel, dual phase steel (F51/F55), titanium alloy, aluminium bronze, INCONEL, SS304, SS304L, SS316, SS316L, chrome molybdenum steel, Monel (400/500), 20# ingxubevange, Hastelloy nezinye izinto zensimbi.

3. Izici zesakhiwo se-i-valve yokuhlola i-wafer:

A. Ubude besakhiwo bufushane, futhi ubude bayo besakhiwo buyi-1/4 ~ 1/8 kuphela yevalve yokuhlola ye-flange evamile.

B. Usayizi omncane nesisindo esilula, isisindo sawo singu-1/4 ~ 1/20 kuphela we-valve yokuhlola ye-flange yendabuko

C. I-valve disc ivala ngokushesha futhi ukucindezela kwesando samanzi kuncane

D. Womabili amapayipi avundlile noma amapayipi aqondile angasetshenziswa, kulula ukuyifaka

E. Ishaneli yokugeleza ibushelelezi futhi ukumelana noketshezi kuncane

F. Isenzo esibucayi nokusebenza okuhle kokuvala

G. Ukuhamba kwe-valve disc kufushane futhi amandla okuvala okuvala mancane

H. Isakhiwo sonke silula futhi sihlangene, futhi isimo sihle

I. Impilo ende yesevisi nokusebenza okuthembekile

4.TAmaphutha ajwayelekile we-valve yokuhlola yilawa:

A. I-valve disc iphukile

Ukucindezela kwe-medium ngaphambi nangemva kwe-valve yokuhlola kusesimweni sokulinganisela kanye ne-"saw" ehlangene. I-disc ye-valve ivame ukushaywa ngesihlalo se-valve, futhi i-disc ye-valve eyenziwe ngezinto ezithile eziphukayo (njenge-cast iron, ithusi, njll.) iphukile. Indlela yokuvimbela ukusebenzisa i-valve yokuhlola ene-disc njenge-ductile material.

B. Ukubuyela emuva okumaphakathi

Indawo yokuvala yonakele; ukungcola kubanjiwe. Ngokulungisa indawo yokuvala nokuhlanza ukungcola, ukugeleza emuva kungavinjelwa.
