Inhloso yokusebenzisa ama-check valve ukuvimbela ukugeleza kwe-medium, ngokuvamile ekuthunyelweni kwephampu ukuze kufakwe ama-check valve. Ngaphezu kwalokho, ama-check valve kufanele afakwe endaweni yokukhipha i-compressor. Ngokuvamile, ama-check valve kufanele afakwe emishinini, amayunithi noma emigqeni ukuvimbela i-media reflux.
Amavalvu okuhlola ukuphakama okuqondile ngokuvamile asetshenziswa ngobukhulu obujwayelekile bepayipi elivundlile elingu-50mm. Amavalvu okuhlola ukuphakama aqondile angafakwa kokubili emigqeni evundlile neqondile. Ivalvu engezansi ngokuvamile ifakwa kuphela epayipini elivundlile lokungena kwephampu, futhi okuphakathi kugeleza kusuka phansi kuya phezulu.
I-valve yokuhlola i-swing ingenziwa ibe nomfutho ophezulu wokusebenza, i-PN ifike ku-42MPa, kanti i-DN nayo ingaba nkulu kakhulu, ifike ku-2000mm. Ngokwezinto zegobolondo kanye nesivalo, ingasetshenziswa kunoma iyiphi indawo yokusebenza kanye nanoma yiliphi izinga lokushisa lokusebenza. Okuphakathi kwamanzi, umusi, igesi, indawo ebolile, uwoyela, ukudla, imithi njalo njalo. Izinga lokushisa lokusebenza lendawo yokusebenza liphakathi kuka--196 ℃ no-800℃.
Ama-valve okuhlola i-swing avame ukufakwa emigqeni evundlile, kodwa angafakwa futhi emigqeni eqondile noma ethambekele.
I-valve yokuhlola i-butterfly ifaneleka ekucindezelweni okuphansi kanye nobubanzi obukhulu, futhi izikhathi zokufaka zilinganiselwe. Ngoba ingcindezi yokusebenza ye-butterfly check valve ayikwazi ukuba phezulu kakhulu, kodwa ububanzi obujwayelekile bungaba bukhulu kakhulu, bungafinyelela ngaphezu kuka-2000mm, kodwa ingcindezi elinganiselwe ingaphansi kuka-6.4mpa. Ama-valve okuhlola i-butterfly angenziwa abe uhlobo lwe-wafer, ngokuvamile afakwe phakathi kwama-flange amabili epayipi, kusetshenziswa uhlobo loxhumano lwe-clamp.
Amavalvu okuhlola ama-butterfly angafakwa emgqeni ovundlile, oqondile noma othambekele.
I-valve yokuhlola i-diaphragm ifaneleka kalula ekukhiqizeni ipayipi lokushaya amanzi, i-diaphragm ingaba yinhle kakhulu ekuqedeni ukushaya kwamanzi okuphambene nomshini ophakathi nendawo. Ngenxa yokuthi izinga lokushisa lokusebenza kanye nokucindezela kokusetshenziswa kwe-valve yokuhlola i-diaphragm kunqunyelwe yizinto ze-diaphragm, ngokuvamile isetshenziswa epayipini lokushisa elijwayelekile elinomfutho ophansi, ikakhulukazi elifanele ipayipi lamanzi. Izinga lokushisa lokusebenza eliphakathi nendawo elijwayelekile liphakathi kuka--20~120℃, ingcindezi yokusebenza <1.6mpa, kodwa i-valve yokuhlola i-diaphragm ingenza ububanzi obukhulu, i-DN ifike ku-2000mm ngaphezulu.
I-valve yokuhlola i-diaphragm ngenxa yokusebenza kwayo okuhle kakhulu kokungangeni manzi, isakhiwo esilula, izindleko zokukhiqiza eziphansi, ngakho-ke eminyakeni yamuva nje, kunezinhlelo zokusebenza eziningi.
Ngenxa yokuthi uphawu luyibhola elimbozwe ngerabha, ivalvu yokuhlola ibhola isebenza kahle ekuvaleni, ukusebenza okuthembekile kanye nokumelana okuhle nokushaywa kwamanzi. Futhi ngenxa yokuthi uphawu lungaba yibhola elilodwa, futhi lungenziwa lube amabhola amaningi, ngakho-ke lungenziwa lube yi-caliber enkulu. Kodwa uphawu lwayo luyindilinga engenalutho yerabha embozwe, alufanelekeli amapayipi anomfutho ophezulu, lufanelekela kuphela amapayipi anomfutho ophakathi naphansi.
Ngenxa yokuthi izinto zegobolondo zevalvu yokuhlola eyindilinga zingenziwa ngensimbi engagqwali, kanti imbulunga engenalutho yesivalo ingambozwa ngepulasitiki yobunjiniyela be-polytetrafluoroethylene, ingasetshenziswa futhi emzileni wemidiya ebolile evamile.
Lolu hlobo lokushisa lokusebenza kwe-check valve luphakathi kuka-101 ℃ kuya ku-150 ℃, ingcindezi yalo evamile ingu-≤4.0MPa, ububanzi bobubanzi obujwayelekile buphakathi kuka-200 ~ 1200mm.
INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,I-Valve yeSango,Hlola i-Valve,I-Globe Vavlve,Izihlungi ze-Y,I-Acurator kagesi,Ama-Acurators omoya.
