Inhloso yokusebenzisa i-valve yokuhlola ukuvimbela ukubuyela emuva kwe-medium. Ngokuvamile, i-valve yokuhlola kufanele ifakwe lapho kuphuma khona iphampu. Ngaphezu kwalokho,i-valve yokuhlola kufanele futhi ifakwe lapho kuphuma khona i-compressor. Ngamafuphi, ukuze kuvinjwe ukubuyela emuva kwe-medium, i-valve yokuhlola kufanele ifakwe kumshini, idivayisi noma ipayipi.Ngokuvamile, i-valve yokuhlola i-lift eqondile isetshenziswa epayipini elivundlile elinobubanzi obungu-50mm. Amavalvu okuhlola ama-lift angafakwa kuwo womabili amapayipi avundlile naqondile. Ivalvu engezansi ivamise ukufakwa epayipini elime mpo endaweni yokungena yepompo, kanti ephakathi igeleza isuka phansi iye phezulu. I-valve yokuhlola i-swing ingenziwa ibe yingcindezi yokusebenza ephezulu kakhulu, i-PN ingafinyelela ku-42MPa, futhi i-DN ingaba nkulu kakhulu, ifike ku-2000mm noma ngaphezulu. Ngokuya ngezinto zegobolondo nophawu, ingasetshenziswa kunoma iyiphi indawo yokusebenza nanoma yiluphi uhla lokushisa olusebenzayo. Okuphakathi kwamanzi, umusi, igesi, indawo edlayo, uwoyela, ukudla, umuthi, njll. Izinga lokushisa eliphakathi nendawo elisebenzayo liphakathi kuka -196~800℃. Indawo yokufaka i-valve yokuhlola i-swing ayikhawulelwe. Ivamise ukufakwa epayipini elivundlile, kodwa lingaphinda lifakwe epayipini elime mpo noma ipayipi elithambekile.

Izikhathi ezisebenzayo ze-i-valve yokuhlola uvemvaneanengcindezi ephansi kanye nobubanzi obukhulu, futhi izikhathi zokufaka zilinganiselwe. 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. I-valve yokuhlola uvemvane ingenziwa uhlobo lwe-clamp, evame ukufakwa phakathi kwama-flange amabili epayipi, kusetshenziswa ifomu lokuxhuma i-clamp.Indawo yokufaka i-valve yokuhlola uvemvane ayikhawulelwe. Ingafakwa epayipini elivundlile, noma epayipini eliqondile noma ipayipi ethambekele.
Ivalvu yokuhlola i-diaphragm ilungele amapayipi athambekele kwisando samanzi. I-diaphragm ingakwazi ukuqeda kahle isando samanzi esibangelwa ukubuyela emuva kwe-medium. Ngenxa yokuthi izinga lokushisa elisebenzayo kanye nokucindezela kokusetshenziswa kwevalvu yokuhlola i-diaphragm kunqunyelwe okokusebenza kwe-diaphragm, ngokuvamile isetshenziswa kumapayipi anengcindezi ephansi kanye namazinga okushisa avamile, alungele ikakhulukazi amapayipi amanzi kampompi. Izinga lokushisa eliphakathi nendawo elivamile liphakathi -20 ~ 120℃, futhi ingcindezi yokusebenza ingu-<1.6MPa, kodwa i-valve yokuhlola i-diaphragm ingenziwa ngobukhulu obukhulu, futhi i-DN ephezulu ingafinyelela ngaphezu kuka-2000mm. ukumelana nesando, isakhiwo esilula kanye nezindleko eziphansi zokukhiqiza, ngakho-ke zisetshenziswe kabanzi eminyakeni yamuva.
Kusukela uphawu lweI-valve yokuhlola ibhola iyindilinga eboshwe ngenjoloba, inokusebenza okuhle kokuvala, ukusebenza okuthembekile nokumelana nesando samanzi esihle; futhi njengoba uphawu lungaba ibhola elilodwa noma amabhola amaningi, lungenziwa ububanzi obukhulu. Kodwa-ke, uphawu lwayo luyindilinga engenalutho eboshwe ngenjoloba, engafaneleki amapayipi anengcindezi ephezulu, kodwa kuphela amapayipi anomfutho ophakathi nendawo. indawo engenalutho yophawu ingambozwa ngamapulasitiki obunjiniyela be-polytetrafluoroethylene, ingasetshenziswa futhi kumapayipi anemidiya evamile egqwalayo. Izinga lokushisa elisebenzayo lalolu hlobo lwe-valve yokuhlola liphakathi kwe- -101 ~ 150 ℃, ingcindezi yamagama ingu-≤4.0MPa, futhi ububanzi obujwayelekile buphakathi kuka-200 ~ 1200mm.
