Ukuhlukaniswa nokufakwa kwesiqondiso sama-valve okuhlola
Uhlolojikelele lwe-valve yokuhlola
Ama-valve okuhlola ayithuluzi elibalulekile lokulawula uketshezi, elisetshenziswa kakhulu kumaphrojekthi okonga amanzi, amakhemikhali e-petrochemicals, ukuvikelwa kwemvelo kanye neminye imikhakha.Umsebenzi wayo oyinhloko ukuvimbela ukubuyela emuva kwemidiya kanye nokuqinisekisa ukugeleza kwendlela eyodwa kwemidiya ohlelweni lwamapayipi.Ukuhlukaniswa nokufakwa kwesiqondiso sama-valve okuhlola kuthinta ngokuqondile ukusebenza kwawo kanye nempilo yesevisi.Lesi sihloko sizokwethula izinhlobo ezahlukene zama-valve okuhlola kanye nokucatshangelwa kwezikhombisi-ndlela zabo zokufaka ngokuningiliziwe.
Izinhlobo eziyinhloko zama-valve okuhlola
Ngokusho kwesakhiwo kanye nesimiso sokusebenza, ama-valve okuhlola ahlukaniswe ikakhulukazi lezi zinhlobo ezilandelayo:
1. I-valve yokuhlola ipuleti eliphindwe kabili
2. Phakamisa i-valve yokuhlola
3. I-valve yokuhlola ibhola
4. I-valve yokuhlola i-Swing
Uhlobo lwesiqondiso sokufakwa kwe-valve yokuhlola
1. Ukufakwa okuvundlile: ibhekisela endleleni yokufaka i-valve yokuhlola epayipini elivundlile, elivame ukusetshenziswa ezinhlelweni zamapayipi anengcindezi ephansi, futhi ububanzi be-flap ye-valve bukhulu kunobubanzi bepayipi.
2. Ukufakwa okuqondile: ibhekisela endleleni yokufaka i-valve yokuhlola epayipini elime mpo, elivame ukusetshenziswa ezinhlelweni zamapayipi anomfutho ophezulu, futhi ububanzi be-flap ye-valve buncane kunobubanzi bepayipi.
1. Ivalvu yokuhlola idiski ephindwe kabili
I-valve yokuhlola amadiski amabili: ngokuvamile iqukethe ama-disc amabili e-semicircular ahamba azungeze i-stem perpendicular to the centerline of the fluid flow.Ama-valve okuhlola ama-double disc angama-valve ahlangene anobude obuncane.Zifakwe phakathi kwama-flange amabili.Ngokuvamile ziboshiwe noma ziboshwe.Ngokuvamile asetshenziswa kumapayipi anobubanzi obungu-≤1200mm.
Isiqondiso sokufakwa kwe-valve yokuhlola i-Double-disc
Amavalvu okuhlola amadiski amabili angafakwa avundlile noma ame mpo epayipini.Ukufakwa okuvundlile kungenza ukuvulwa nokuvalwa kwe-valve yokuhlola ethintwe amandla adonsela phansi, okwenza isivinini sayo sokuvula sizinze futhi sinciphise ngempumelelo ukulahlekelwa kwengcindezi yepayipi.Ukufakwa okuqondile kungenza i-valve ithinteke amandla adonsela phansi lapho ivaliwe, okwenza uphawu lwayo luqine.Ukwengeza, ukufakwa okuqondile kungavimbela i-disc ye-valve yokuhlola ukuthi ingadli ngokushesha ngesikhathi sokushintsha okusheshayo koketshezi, ukunciphisa ukugqoka kokudlidliza kwe-disc nesihlalo se-valve, futhi kwandise impilo yesevisi ye-valve.
2. I-valve yokuhlola i-Swing
Swayipha ama-valve okuhlolaube nediski ye-valve.Lapho i-medium igeleza phambili, i-valve disc iphushwa ivuleke;lapho i-medium igeleza ibheke emuva, i-valve disc ihlwithwa ibuyele esihlalweni se-valve ukuvimbela ukugeleza emuva.Lolu hlobo lwe-valve luvame ukusetshenziswa emapayipini anobubanzi obukhulu ngenxa yesakhiwo sawo esilula nokumelana okuphansi.
Isiqondiso sokufakwa kwe-Swing check valve
Ama-valve okuhlola ama-Swing angafakwa avundlile noma aqonde phezulu, kodwa ngokuvamile atuswa ukuba afakwe kumapayipi avundlile.Kumele kuqashelwe ukuthi, kuye ngokuthi isimo sangempela, i-valve yokuhlola i-swing ingabuye ifakwe ngokuzenzakalelayo, inqobo nje uma i-angle yokufaka ingeqi ama-degree angama-45 futhi indawo yokufaka ifanelekile, ngeke ithinte imisebenzi evamile yokuvula nokuvala. kwe-valve.
3. I-valve yokuhlola i-lift evundlile
I-valve disc yevalvu yokuhlola i-lift evundlile iye phezulu naphansi eduze kwesitimela esiqondisayo emzimbeni wevalvu.Lapho i-medium igeleza phambili, i-valve disc iyaphakanyiswa;lapho i-medium igeleza ibheke emuva, i-valve disc iwela emuva esihlalweni se-valve ukuvimbela ukubuyela emuva.
Isiqondiso sokufakwa kwevalvu yokuhlola i-Horizontal lift
Ivalvu yokuhlola i-lift evundlile kufanele ifakwe epayipini elivundlile.Ngoba uma ifakwe iqonde phezulu, ingqikithi ye-valve isesimweni esivundlile, ukusebenza kwayo okumaphakathi nesihlalo se-valve kuncipha ngaphansi kwesisindo saso, okuthinta ukusebenza kokuvala kwe-valve core.
4. I-valve yokuhlola i-vertical lift
Ukuze mpophakamisa ama-valve okuhlola, isiqondiso sokunyakaza kwe-valve core sihambisana nesiqondiso sepayipi.Futhi isikhungo se-valve core sihambisana nesikhungo somzila wokugeleza.
Isiqondiso sokufakwa kwevalvu yokuhlola i-Vertical lift
Ama-valve okuhlola aqondile kufanele afakwe ame mpo emapayipini lapho okuphakathi kugeleza ukuya phezulu, ngoba amandla adonsela phansi asiza i-valve disc ivale ngokushesha lapho ukugeleza kuma.
5. I-valve yokuhlola ibhola
Ivalve yokuhlola ibhola isebenzisa ibhola elihamba liye phezulu naphansi emzimbeni wevalvu.Lapho i-medium igeleza phambili, ibhola lidudulwa kude nesihlalo se-valve, isiteshi siyavuleka, futhi amaphasi aphakathi;lapho i-medium igeleza ibheke emuva, ibhola libuyela esihlalweni se-valve ukuvimbela ukubuyela emuva.
Isiqondiso sokufakwa kwe-valve yokuhlola i-Ball
Ama-valve okuhlola amabhola angafakwa kumapayipi avundlile, kodwa afaneleka kakhulu ukufakwa mpo, ikakhulukazi uma okuphakathi kugeleza kuya phezulu.Isisindo esifile sebhola sisiza i-valve ukuthi ivaleke lapho ukugeleza kuma.
Izinto ezithinta ukufakwa okuqondile kwe-valve yokuhlola
Lapho ufaka i-valve yokuhlola ngokuqondile, izici eziningana zidinga ukucatshangelwa ukuze kuqinisekiswe ukusebenza kwayo ngempumelelo:
1. Isiqondiso sokugeleza
Ekufakeni okuqondile, isiqondiso sokugeleza kwe-medium sibalulekile.Lapho igeleza phezulu, i-disc ye-valve ingavulwa ngokucindezelwa kwe-medium, futhi ukuvala amandla adonsela phansi okusiza i-valve disc ibuyele endaweni yayo, kuyilapho igeleza phansi, izinyathelo ezengeziwe zingadingeka ukuze kuqinisekiswe ukuthi i-valve ivala ngokuthembekile.
2. Umphumela wamandla adonsela phansi
Amandla adonsela phansi athinta ukuvulwa nokuvalwa kwe-valve.Amavaluvu ancike kumandla adonsela phansi ukuze avale, njenge-double plate kanye namavalvu okuhlola okuphakamisa, asebenza kangcono uma egeleza aqonde phezulu.
3. Izici zemidiya
Izici zemidiya, njenge-viscosity, ukuminyana, nokuqukethwe kwezinhlayiyana, kuthinta ukusebenza kwe-valve.I-Viscous noma imidiya equkethe izinhlayiyana ingase idinge ukwakheka okuqinile nokugcinwa njalo ukuze kuqinisekiswe ukusebenza okuthembekile kwe-valve.
4. Indawo yokufaka
Indawo yokufaka, okuhlanganisa izinga lokushisa, ingcindezi, nokuba khona kwezinto ezonakalisayo, kuzothinta ukusebenza nokuphila kwe-valve.Ukukhetha izinto zokwakha kanye nemiklamo efanelekile endaweni ethile kungandisa impilo yesevisi ye-valve.
Izinzuzo zokufakwa okuqondile i-valve yesheke
1. Ukusetshenziswa kwamandla adonsela phansi
Endabeni yokugeleza okuya phezulu kwemidiya, amandla adonsela phansi asiza i-valve ukuthi ivale, ithuthukise ukusebenza kokuvala, futhi ayidingi usizo lwangaphandle.
2. Yehlisa ukuguga
Ukusebenzisa amandla adonsela phansi abezindaba kanye nepuleti ye-valve ukuvala i-valve yokuhlola kunganciphisa ukudlidliza, kunciphise ukuguga, kunwebe impilo yesevisi ye-valve, futhi kunciphise imvamisa yokugcinwa.
Ukungalungi kokufakwa okuqondilei-valve yesheke
1. Ukumelana nokugeleza
Ukufakwa okuqondile kungase kwandise ukumelana nokugeleza, ikakhulukazi kuma-valve okuhlola ukuphakamisa okuqondile, okudingeka amelane hhayi kuphela nesisindo sepuleti le-valve, kodwa futhi nokucindezela okunikezwa isiphethu ngaphezu kwepuleti le-valve.Lokhu kuzoholela ekunciphiseni ukugeleza nokwanda kokusetshenziswa kwamandla.
2. Isenzo sesando samanzi
Lapho okuphakathi kugeleza kuya phezulu, amandla evalve yokuhlola kanye namandla adonsela phansi okuphakathi azokwandisa ukucindezela epayipini, okwenza kube lula ukubangela isenzakalo sesando samanzi.
