Yiziphi izinhlobo kanye nemininingwane yama-check valve

Ama-valve okuhlola atholakala ngezinhlobo ezahlukene kanye nezincazelo ngokuya ngezici ezifana nesimo sesakhiwo, izinto kanye nokusetshenziswa. Okulandelayo isifinyezo esinemininingwane yezinhlobo kanye nezincazelo zama-valve okuhlola:

Okokuqala, uhlobo

1. Ukuhlukaniswa ngesakhiwo

Ivalvu yokuhlola i-lift: Ivalvu yokuhlola enediski eshelelayo emgqeni ophakathi womzimba oqondile. Le valve ingafakwa kuphela epayipini elivundlile, i-coefficient yokumelana noketshezi inkulu. Uma i-medium isendleleni yokugeleza, idiski yevalvu ivulwa ngokusunduza kwe-medium. Lapho i-medium iyeka ukugeleza, idiski yevalvu iwela esihlalweni ngesisindo sayo ukuvimbela i-medium ukuthi ingangeni ku-countercurrent. Ivalvu yokuhlola i-lift inezinhlobo ezimbili ze-straight through kanye ne-vertical, i-straight lift check valve medium inlet kanye ne-outlet channel direction kanye ne-set channel direction perpendicular, kanye ne-vertical lift check valve medium inlet kanye ne-outlet channel direction kanye ne-set channel direction kuyafana, ukumelana kwayo nokugeleza kuncane kunohlobo oluqondile.

I-valve yokuhlola eshukumayo: I-valve yokuhlola enediski emise okwediski kanye nokunyakaza okujikelezayo okuzungeze umgodi ojikelezayo wesiteshi sesihlalo. Ukumelana kwayo ngokuvamile kuncane kune-valve yokuhlola ephakamisayo, efaneleka emicimbini emikhulu ye-caliber. Ama-valve okuhlola eshukumayo angahlukaniswa futhi abe yi-valve eyodwa, i-valve ephindwe kabili kanye ne-multi-valve ngokuya ngenani lama-valve, inhloso eyinhloko ukuvimbela i-medium ukuthi ingayeki ukugeleza noma ukugeleza okuphambene, okwenza kube buthaka umthelela we-hydraulic.

Ivalvu yokuhlola i-Butterfly: Ivalvu yokuhlola enediski ezungeza iphini esihlalweni. Ivalvu yokuhlola idiski ilula ngesakhiwo, ingafakwa kuphela epayipini elivundlile, futhi ayinaso isivalo esihle.

I-valve yokuhlola ipayipi: I-valve yokuhlola enediski eshelelayo eceleni komugqa ophakathi womzimba. Iyi-valve esanda kuvela, encane, isisindo esincane, ubuchwepheshe obuhle bokucubungula, ingenye yezindlela zokuthuthukiswa kwama-valve okuhlola.

I-valve yokuhlola ingcindezi: Le valve inomsebenzi ohlangene we-lift check valve kanye ne-globe valve noma i-Angle valve, futhi ivame ukusetshenziswa njenge-boiler feed water and steam cut-off valve.

Ezinye izinhlobo: Zihlanganisa futhi ivalvu yokuhlola uhlobo lwesisindo, ivalvu yokuhlola uhlobo lwesitsha, ivalvu yokuhlola idiski yamabhuleki, ivalvu yokuhlola uhlobo lwebhola, ivalvu yokuhlola uhlobo lwe-diaphragm.

2. Hlela ngezinto ezibonakalayo

I-valve yokuhlola insimbi: njenge-valve yokuhlola insimbi ephonswe, i-valve yokuhlola ithusi, i-valve yokuhlola insimbi engagqwali, i-valve yokuhlola insimbi yekhabhoni, i-valve yokuhlola insimbi eyenziwe ngobumba, njll.

I-valve yokuhlola engeyona eyensimbi: njenge-valve yokuhlola yepulasitiki, i-valve yokuhlola ye-FRP, njll.

3. Hlela ngezigaba ngomsebenzi

I-valve yokuhlola ethule: njenge-valve yokuhlola ethule ye-DRVZ, i-valve yokuhlola ethule ye-DRVG, i-valve yokuhlola ethule ye-NRVR, njll.

I-valve yokuhlola yenhloso ekhethekile: njenge-valve yokuhlola i-flap yerabha ye-SFCV, i-valve yokuhlola i-flap ephindwe kabili ye-DDCV, njll.

Okwesibili, imininingwane

Imininingwane yevalvu yokuhlola ivame ukuvezwa ububanzi obujwayelekile (i-DN), kanti imininingwane evamile yi-DN15, DN25, DN50, DN80, DN100, DN150, njll. Ngaphezu kwalokho, kunemininingwane efana namazinga okucindezela, izinhlobo zokuxhuma (njengokuxhuma okunezintambo, okune-flange, okuhlanganisiwe kanye nokuxhumanisa kwe-clamp).

Isibonelo, incazelo yevalvu yokuhlola intwasahlobo yentambo yangaphakathi ye-H12W yi-DN15-100mm, kanti isigaba sokucindezela siyi-1.6-32MPa; Imininingwane yamavalvu okuhlola ama-butterfly anediski eliphindwe kabili i-H76H kanye ne-H76W yi-DN50-1200mm, kanti isigaba sokucindezela siyi-1.6-10MPa.

Okwesithathu, khetha iziphakamiso

Uma ukhetha i-check valve, kubalulekile ukucabangela izici ezifana nohlelo oluthile lwamapayipi, izici eziphakathi nendawo, ingcindezi yokusebenza kanye nokushisa. Nazi ezinye izinketho:

Khetha uhlobo lwevalvu yokuhlola olufanele kanye nencazelo ngokuya ngendlela yokugeleza kanye nosayizi wokugeleza kwe-medium.

Cabanga ngokugqwala kwesilinganiso esiphakathi, i-viscosity kanye nezinga lokushisa kanye nezinye izinto, khetha izinto ezifanele.

Khetha imodi yokuxhuma efanele ngokusekelwe endaweni yokufaka kanye nezidingo zokugcinwa kwesistimu yamapayipi.

Bheka ikhathalogi yomkhiqizo womenzi kanye neshidi lemininingwane yobuchwepheshe ukuqinisekisa ukuthi i-check valve ekhethiwe ihlangabezana nezidingo zesistimu.

Ngamafuphi, kunezinhlobo ezahlukene kanye nezincazelo zama-check valve, futhi ukukhetha kufanele kucatshangelwe ngokuphelele ngokwezidingo zangempela.
