Isingeniso sohlelo lokusebenza, izinto eziyinhloko kanye nezici zesakhiwo se-valve yokuhlola ipuleti eliyisicwecwana elikabili

I-waferipuleti ezimbilihlola i-valveibhekisela ku-valve evula ngokuzenzakalelayo futhi ivale i-flap ye-valve ngokuthembela ekugelezeni kwe-medium ngokwayo ukuze kuvinjelwe ukubuyela emuva kwe-medium, eyaziwa nangokuthi i-valve yokuhlola, i-valve yendlela eyodwa, i-valve yokugeleza ehlehlayo kanye ne-valve yokucindezela emuva. I-waferipuleti ezimbilihlola i-valveiyi-valve ezenzakalelayo umsebenzi wayo oyinhloko uwukuvimbela ukubuyela emuva kwe-medium, ukuvimbela ukuzungezisa okubuyela emuva kwepompo kanye nenjini yokushayela, nokukhipha okuphakathi esitsheni. I-waferipuleti ezimbiliama-valve okuhlola angasetshenziswa futhi emigqeni ehlinzeka ngezinhlelo ezisizayo lapho ukucindezela kungase kukhuphuke ngaphezu kokucindezela kwesistimu.

1. Isicelo sevalvu yokuhlola ipuleti eliphindwe kabili:

I-waferipuleti ezimbilihlola i-valveifakwe ohlelweni lwamapayipi, futhi umsebenzi wayo oyinhloko ukuvimbela ukubuyela emuva kwe-medium. Isinkwa esilucwecwanaipuleti ezimbilihlola i-valveiyi-valve ezenzakalelayo evulekayo futhi ivalwe kuye ngomfutho ophakathi. Uhlobo lwe-waferipuleti ezimbilihlola i-valveifanele ingcindezi okuzisholo PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; ububanzi okuzisholo DN15~1200mm, NPS1/2~48; izinga lokushisa lokusebenza -196 ~ 540 ℃ kumapayipi ahlukahlukene, asetshenziselwa ukuvimbela ukubuyela emuva kwe-medium. 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. Impahla eyinhloko ye-waferipuleti ezimbilii-valve yokuhlola:

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 seipuleti ezimbilii-valve yokuhlola:

1. Ubude besakhiwo bufushane, futhi ubude baso besakhiwo buyi-1/4~1/8 kuphela ye-flanged evamile.shwibahlola i-valve.

2. Usayizi omncane nesisindo esincane, isisindo sawo singu-1/4~1/20 kuphela we-flanged yendabuko.shwibahlola i-valve.

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 okuhle 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 avamile weipuleti ezimbilii-valve yokuhlola yilezi:

1. I-valve disc iphukile

Ingcindezi ye-medium ngaphambi nangemuva kwe-ipuleti ezimbilihlola i-valveisesimweni sokulinganisela futhi "saw" ngokufanayo. I-disc ye-valve ivame ukushaywa ngesihlalo se-valve, futhi i-disc ye-valve eyenziwe ngezinto ezithile eziphukayo (njenge-cast iron, ithusi, njll.) iyashaywa. ephukile.

Indlela yokuvimbela ukusebenzisa aipuleti ezimbilihlola i-valve nge-disc njenge-ductile material.

2. Ukubuyela emuva okumaphakathi

Indawo yokuvala yonakele; ukungcola kubanjiwe.

Ngokulungisa indawo yokuvala nokuhlanza ukungcola, ukugeleza emuva kungavinjelwa.
