Inhloso yokusebenzisa i-valve yokuhlola ukuvimbela ukugeleza okubuyela emuva kwe-medium, futhi i-valve yokuhlola ivame ukufakwa lapho kuphuma iphampu. Ngaphezu kwalokho, i-valve yokuhlola kufanele futhi ifakwe endaweni yokuphuma kwe-compressor. Ngamafuphi, ukuze kuvinjelwe ukugeleza okubuyela emuva kwe-medium, i-valve yokuhlola kufanele ifakwe kumshini, idivayisi noma ipayipi.
Ngokuvamile, ama-valve okuhlola ukuphakamisa okuqondile asetshenziswa kumapayipi avundlile anobubanzi obungu-50mm. Ivalvu yokuhlola i-lift ingafakwa kuwo womabili amapayipi avundlile naqondile. Ivalvu engezansi ivamise ukufakwa kuphela epayipini elime mpo le-pump inlet, kanti ephakathi igeleza ukusuka phansi ukuya phezulu.
I-valve yokuhlola i-Swing ingenziwa ibe yingcindezi yokusebenza ephezulu kakhulu, i-PN ingafinyelela ku-42MPa, futhi i-DN nayo ingenziwa ibe nkulu kakhulu, inani eliphakeme lingafinyelela ngaphezu kuka-2000mm. Ngokwezinto ezihlukene zegobolondo kanye ne-seal, ingasetshenziswa kunoma iyiphi indawo yokusebenza nanoma yiluphi uhla lokushisa olusebenzayo. Okuphakathi kwamanzi, isitimu, igesi, i-corrosive medium, uwoyela, ukudla, imithi, njll. Izinga lokushisa elisebenzayo lendawo liphakathi kuka -196~800℃.
Isikhundla sokufakwa kwe-valve yokuhlola i-swing ayinqunyelwe, ivamise ukufakwa epayipini elivundlile, kodwa ingabuye ifakwe epayipini eliqondile noma ipayipi ethambekele.
Isikhathi esisebenzayo se-valve yokuhlola uvemvane ukucindezela okuphansi nobubanzi obukhulu, futhi isikhathi sokufaka sinqunyelwe. Ngenxa yokuthi ukucindezela kokusebenza kwe-valve yokuhlola i-butterfly akukwazi ukuba phezulu kakhulu, kodwa ububanzi obujwayelekile bungaba bukhulu kakhulu, obungafinyelela ngaphezu kwe-2000mm, kodwa ukucindezela okubizwa ngokuthi kungaphansi kwe-6.4MPa. Ivalve yokuhlola uvemvane ingenziwa uhlobo oluyisicwecwana, oluvame ukufakwa phakathi kwamaphethelo amabili epayipi ngendlela yokuxhuma kwe-wafer.
Indawo yokufaka i-valve yokuhlola uvemvane ayinqunyelwe, ingafakwa epayipini elivundlile, ipayipi eliqondile noma ipayipi ethambekele.
Ivalvu yokuhlola i-diaphragm ilungele amapayipi athambekele kwisando samanzi. I-diaphragm ingakwazi ukuqeda kahle isando samanzi esibangelwa ukugeleza okuphambene kwe-medium. Njengoba izinga lokushisa lokusebenza nokucindezela kokusebenza kwamavalvu okuhlola i-diaphragm kunqunyelwe into ye-diaphragm, ngokuvamile asetshenziswa kumapayipi anengcindezi ephansi kanye namazinga okushisa avamile, ikakhulukazi amapayipi amanzi kampompi. Ngokuvamile, izinga lokushisa elisebenzayo le-medium liphakathi -20 ~ 120 ℃, futhi ingcindezi yokusebenza ingaphansi kwe-1.6MPa, kodwa i-valve yokuhlola i-diaphragm ingafinyelela ububanzi obukhulu, futhi i-DN ephezulu ingaba ngaphezu kuka-2000mm.
Ivalvu yokuhlola i-diaphragm ibisetshenziswa kabanzi eminyakeni yamuva nje ngenxa yokusebenza kwayo okuhle kakhulu okungangeni manzi, ukwakheka kwayo okulula kanye nezindleko eziphansi zokukhiqiza.
I-valve yokuhlola ibhola inokusebenza okuhle kokuvala, ukusebenza okuthembekile kanye nokumelana kahle kwesando samanzi ngoba uphawu luyindilinga embozwe ngenjoloba; futhi ngenxa yokuthi uphawu lungaba ibhola elilodwa noma amabhola amaningi, lungenziwa lube ububanzi obukhulu. Kodwa-ke, uphawu lwayo luyindilinga engenalutho embozwe ngenjoloba, engafanele amapayipi anengcindezi ephezulu, kodwa efanelekile kuphela kumapayipi aphakathi nendawo naphansi.
Njengoba impahla yegobolondo yevalvu yokuhlola ibhola ingenziwa ngensimbi engagqwali, futhi indawo engenalutho yophawu ingambozwa ngepulasitiki yobunjiniyela be-PTFE, ingasetshenziswa futhi kumapayipi anemidiya egqwalayo evamile.
Izinga lokushisa elisebenzayo lalolu hlobo lwe-valve yokuhlola liphakathi -101 ~ 150℃, ingcindezi yamagama ingu-≤4.0MPa, futhi ububanzi bobubanzi obujwayelekile buphakathi kuka-200 ~ 1200mm.
