Izinhlobo zama-Check Valves

Hlola i-valve, eyaziwa nangokuthi i-valve yendlela eyodwa noma i-valve yokuhlola, iyingxenye ye-automatic valve, futhi umsebenzi wayo ukuvimbela ukugeleza emuva kwe-medium epayipini.I-valve engezansi esetshenziselwa ukumunca iphampu iwuhlobo lwevalvu yokuhlola.I-disc ye-valve yokuhlola ivulwa ngaphansi kwesenzo sokucindezela kwamanzi, futhi uketshezi lugeleza lusuka ekungeneni luye endaweni yokuphuma.Lapho ingcindezi yokungena iphansi kune-outlet, i-valve flap ivalwa ngokuzenzakalelayo ngaphansi kwesenzo somehluko we-fluid pressure, amandla adonsela phansi nezinye izici ukuvimbela uketshezi ukuthi lungabuyeli emuva.

Ukuhlukaniswa kwama-valve okuhlola kungahlukaniswa ngezinhlobo ezahlukene ngokusho kwempahla, umsebenzi kanye nesakhiwo.Okulandelayo kuzokwethula izinhlobo zamavalvu okuhlola avela kulezi zici ezintathu.

1. Ukuhlukaniswa ngokwezinto ezibonakalayo

1) I-valve yokuhlola insimbi

2) I-valve yokuhlola ithusi

3) I-valve yokuhlola insimbi engagqwali

2. Ukuhlukaniswa ngomsebenzi

1) I-valve yokuhlola ethule

2) I-valve yokuhlola ibhola

I-valve yokuhlola ibhola ibizwa nangokuthi i-valve yokuhlola indle.Umzimba we-valve wamukela isakhiwo sesiteshi esigcwele, esinezinzuzo zokugeleza okukhulu nokumelana okuphansi.Ibhola lisetshenziswa njenge-disc ye-valve, efanelekile kumanethiwekhi wamapayipi okuthuthwa kwendle ezimbonini nasekhaya ane-viscosity ephezulu kanye nezinto eziqinile ezimisiwe.

3. Ukuhlukaniswa ngesakhiwo

1) Phakamisa i-valve yokuhlola

2) I-valve yokuhlola i-Swing

3) I-valve yokuhlola i-Butterfly

Ukwakheka kwe-valve yokuhlola i-lift ngokuvamile kufana ne-valve yembulunga.I-valve disc iya phezulu naphansi eduze komugqa esiteshini, futhi isenzo sinokwethenjelwa, kodwa ukumelana noketshezi kukhulu, futhi kufanelekile ngezikhathi ezinobubanzi obuncane.I-valve yokuhlola i-Lift ihlukaniswe yaba izinhlobo ezimbili: uhlobo oluvundlile kanye nohlobo oluqondile.Amavalvu okuhlola ukuphakamisa aqonde ngokuvamile angafakwa kuphela kumapayipi avundlile, kuyilapho amavalvu okuhlola ame mpo namavalufu aphansi ngokuvamile afakwa kumapayipi aqondile, kanti okuphakathi kugeleza ukusuka phansi kuye phezulu.

I-disc ye-valve yokuhlola i-swing izungeza i-axis yokujikeleza.Ukumelana kwayo noketshezi ngokuvamile kuncane kunaleyo yevalvu yokuhlola i-lift, futhi ifanele izikhathi ezinobubanzi obukhulu.Ngokusho kwenombolo yama-disc, i-valve yokuhlola i-swing ingahlukaniswa ngezinhlobo ezintathu: uhlobo lwe-single disc swing, uhlobo lwe-disc swing ephindwe kabili kanye nohlobo lwe-multi disc swing.I-valve yokuhlola i-flap eyodwa ngokuvamile ifanele izikhathi zobubanzi obuphakathi.Uma i-valve yokuhlola i-flap eyodwa isetshenziselwa amapayipi anobubanzi obukhulu, ukuze kuncishiswe umfutho wesando samanzi, kungcono ukusebenzisa i-valve yokuhlola evala kancane enganciphisa umfutho wesando samanzi.Ivalvu yokuhlola i-flap ephindwe kabili ifanele amapayipi amakhulu naphakathi nobubanzi.I-wafer double flap swing check valve incane ngesakhiwo futhi ilula ngesisindo, futhi iwuhlobo lwevalvu yokuhlola ethuthuka ngokushesha.I-Multi-lobe swing check valve ifanele amapayipi amakhulu obubanzi.

Indawo yokufaka i-valve yokuhlola i-swing ayinqunyelwe, ivamise ukufakwa epayipini elivundlile, kodwa ingabuye ifakwe epayipini eliqondile noma ipayipi lokulahla.

Ukwakheka kwe-valve yokuhlola uvemvane kufana ne-valve uvemvane.Isakhiwo saso silula, ukumelana nokugeleza kuncane, futhi ukucindezela kwesando samanzi nakho kuncane.

Izindlela zokuxhuma ze-valve yokuhlola zihlanganisa ukuxhumeka kwesiqeshana, uxhumano lwe-flange, uxhumano lwentambo, uxhumano lwe-butt welding/socket welding, njll. Ibanga lokushisa elisebenzayo lingu-196℃~540℃.Izinto zokwakha ze-valve ziyi-WCB, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L).Khetha izinto ezahlukene zemidiya ehlukene.I-valve yokuhlola ingasetshenziswa emanzini, umusi, uwoyela, i-nitric acid, i-acetic acid, i-oxidizing medium, i-urea neminye imidiya.

Lapho ufaka i-valve yokuhlola, ukunakwa okukhethekile kufanele kukhokhwe ekuqondeni kokugeleza kwe-medium, futhi isiqondiso sokugeleza esivamile se-medium kufanele sihambisane nesiqondiso somcibisholo okhonjiswe emzimbeni we-valve, ngaphandle kwalokho ukugeleza okujwayelekile kwe-medium kuzoba. anqunywe.I-valve engezansi kufanele ifakwe ekugcineni phansi komugqa wokumunca wepompo.

Lapho ivalvu yokuhlola ivaliwe, umfutho wesando samanzi uzokhiqizwa epayipini, okuzodala umonakalo kuvalvu, ipayipi noma impahla ezimweni ezimbi kakhulu, ikakhulukazi kumapayipi anomlomo omkhulu noma amapayipi anomfutho ophezulu, sicela unakisise.
