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

Hlola i-valveibhekisela ku-valve evula ngokuzenzakalelayo futhi ivale i-flap ye-valve ngokuthembela ekugelezeni kwe-medium ngokwayo ukuvimbela ukubuyela emuva kwe-medium, eyaziwa nangokuthi i-valve yokuhlola, i-valve yendlela eyodwa, i-valve yokugeleza ehlehlayo kanye ne-valve yokucindezela emuva.I-valve yokuhlola iyi-valve ezenzakalelayo umsebenzi wayo oyinhloko ukuvimbela ukubuyela emuva kwe-medium, ukuzungeza okuphambene kwepompo kanye ne-motor yokushayela, kanye nokukhishwa kwe-container medium.Amavalvu okuhlola angasetshenziswa emigqeni ehlinzeka ngamasistimu asizayo lapho ukucindezela kungase kukhuphuke ngaphezu kokucindezela kwesistimu.

1. Isicelo sevalvu yokuhlola i-wafer:

I-valve yokuhlola ifakwe ohlelweni lwamapayipi, futhi umsebenzi wayo oyinhloko ukuvimbela ukubuyela emuva kwe-medium.I-valve yokuhlola i-valve ezenzakalelayo evuliwe futhi ivaliwe kuye ngokuthi ingcindezi ye-medium.I-valve yokuhlola i-waferifanele ingcindezi okuzisholo PN1.0MPa ~ 42.0MPa, Class150 ~ 25000;ububanzi okuzisholo DN15~1200mm, NPS1/2~48;izinga lokushisa lokusebenza -196 ~ 540 ℃ kumapayipi ahlukahlukene, asetshenziselwa ukuvimbela ukugeleza 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.

Okwesibili, izinto eziyinhloko ze-valve yokuhlola i-wafer: 

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

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

1. Ubude besakhiwo bufushane, futhi ubude baso besakhiwo buyi-1/4~1/8 kuphela yevalvu yokuhlola ye-flange evamile.

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

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

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

5. Ishaneli yokugeleza ibushelelezi futhi ukumelana noketshezi kuncane

6. Isenzo esibucayi kanye nokusebenza kahle kokuvala

7. Ukuhamba kwe-valve disc kufushane futhi amandla omthelela wokuvala mancane

8. Isakhiwo sonke silula futhi sihlangene, futhi isimo sihle

9. Impilo ende yesevisi nokusebenza okuthembekile

Okwesine, amaphutha ajwayelekile e-valve yokuhlola yilawa:

1. I-valve disc iphukile

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

2. Ukubuyela emuva okumaphakathi

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