Inhloso yekusebentisa ivalve yekuhlola kuvikela kugeleta lokubuyela emuva kwemkhatsi, futsi ivalve yekuhlola ivame kufakwa lapho kuphuma khona impompi. Ngetulu kwaloko, kufanele kuphindze kufakwe i-valve yekuhlola lapho kuphuma khona i-compressor. Ngamafuphi, kwentela kuvikela kugeleta lokubuyela emuva kwemkhatsi, kumele kufakwe i-valve yekuhlola kulemishini, kuledivayisi noma kuleliphayiphi.
Ngalokuvamile, emavalvu ekuhlola ekuphakamisa lamile asetjentiswa kumaphayiphi lavundlile lanebubanti lobubitwa ngekutsi ngu 50mm. Ivalve yekuhlola yekuphakamisa lecondzile ingafakwa kuwo womabili emaphayiphi lavundlile nalamile. Ivalve lephansi ivame kufakwa kuphela kuphayiphi lemile yekungena kwempompi, bese lesemkhatsini igeleta kusuka phansi kuya etulu.
Swing check valve ingentiwa ibe ngumfutfo lomkhulu kakhulu wekusebenta, PN ingafinyelela ku 42MPa, futsi DN ingaphindze yentiwe ibe yinkulu kakhulu, lephakeme ingafinyelela ngetulu kwa 2000mm. Ngekuya kwetintfo letehlukene teligobolondvo kanye nesivalo, ingasetjentiswa kunoma nguyiphi indlela yekusebenta kanye nanobe nguyiphi indlela yekushisa lesebentako. Lendzawo lesemkhatsini ngemanti, umfutfo, igesi, lendzawo leguculako, oyili, kudla, imitsi, njll.
Indzawo yekufakwa kwe-swing check valve ayilinganiselwe, ivame kufakwa ephayiphini levundlile, kepha ingaphindze ifakwe ephayiphini lemile noma ephayiphini lethambekile.
Umcimbi losebentako we-valve yekuhlola butterfly ngumfutfo lophansi kanye nebubanti lobukhulu, futsi umcimbi wekufakwa ulinganiselwe. Ngoba umfutfo wekusebenta we butterfly check valve angeke ube ngetulu kakhulu, kepha umfutfo wekubita ungaba mkhulu kakhulu, longafika ngetulu kwa 2000mm, kepha umfutfo wekubita ungaphansi kwa 6.4MPa. Le valve yekuhlola ye butterfly ingentiwa ibe luhlobo lwe wafer, loluvame kufakwa emkhatsini wema flanges lamabili ephayiphi ngendlela yekuhlanganiswa kwe wafer.
Indzawo yekufakwa kwe-valve yekuhlola ye-butterfly ayilinganiselwe, ingafakwa emaphayiphini lavundlile, emaphayiphini lamile noma emaphayiphini lathambekile.
Diaphragm hlola valve ilungele emaphayiphi kutsi kuthambekele isando emanti. Le diaphragm ingacedza kahle isando semanti lesibangelwa kugeleta lokubuyela emuva kwemkhakha. Njengoba lizinga lekushisa lelisebentako kanye nemfutfo wekusebenta wemavalvu ekuhlola e-diaphragm kulinganiselwe yintfo ye-diaphragm, avame kusetjentiswa kumaphayiphi lanekucindzeteleka lokuphansi kanye nekushisa lokujwayelekile, ikakhulukati kumaphayiphi emanti empompi. Ngalokuvamile, lokushisa lokusebenta kwemkhatsi kusemkhatsini wa -20 ~ 120 ° C, futsi umfutfo wekusebenta ungaphansi kwa 1.6 MPa, kepha ivalve yekuhlola ye diaphragm ingafinyelela ububanzi lobukhulu, futsi i DN lephakeme ingaba ngetulu kwa 2000mm.
Diaphragm check valve isetjentiswe kakhulu eminyakeni yamuva ngenca yekusebenta kwayo lokuhle kakhulu lokungangeni emanti, sakhiwo lesilula kanye netindleko letiphansi tekukhicita.
Le valve yekuhlola ibhola inekusebenta lokuhle kwekuvala, kusebenta lokutsembekile kanye nekumelana kahle nesando semanti ngoba le seal iyinkhaba lembonywe ngerabha; futsi ngenca yekutsi lesivalo singaba libhola linye nobe emabhola lamanyenti, singentiwa sibe nebubanti lobukhulu . Nomakunjalo, sivalo sayo siyindingilizi lenembobo lembonywe ngerabha, lengakalungeli emaphayiphi lanemfutfo lomkhulu, kepha ilungele emaphayiphi lanemfutfo losemkhatsini nalophansi kuphela.
Njengobe tintfo teligobolondvo le-valve yekuhlola ibhola ingentiwa ngensimbi lengagucuki, futsi umjikeleto lonemgodzi we-seal ungambonywa ngepulasitiki yebunjiniyela be-PTFE, ingaphindze isetjentiswe emaphayiphini lanetindzaba letigugile jikelele.
Lokushisa lokusebenta kwaloluhlobo lwevalve yekuhlola kusemkhatsini we -101 ~ 150 ° C, umfutfo lobitwako ≤4.0 MPa, kanye nebanga lebubanti lobubitwako lisemkhatsini we 200 ~ 1200mm.
