Imikhiqizo
Ukusebenza okuphezulu kwe-Butterfly Valve
✧ Incazelo
I-valve yevemvane esebenza kahle iwuhlobo lwevalvu eklanyelwe izinhlelo zokusebenza ezinzima ezidinga ukuvalwa okuthembekile, amandla okucindezela okukhulu, nokuvalwa okuqinile.Lawa ma-valve avame ukusetshenziswa ezimbonini ezifana nowoyela negesi, ukucubungula amakhemikhali, ukukhiqizwa kwamandla, nokwelashwa kwamanzi, phakathi kokunye.Abonakala ngekhono lawo lokuhlinzeka ngokulawula ukugeleza okuphumelelayo futhi amelane nezimo zokusebenza eziyinselele.Ezinye izici ezibalulekile zamavalvu ovemvane asebenza kahle zihlanganisa: Ukuvala Okuqinile: Lawa mavalvu enzelwe ukunciphisa ukuvuza futhi anikeze uphawu oluthembekile ngisho nalapho ingcindezi ephezulu. noma izindawo ezinezinga lokushisa eliphezulu.Ukwakhiwa Okuqinile: Amavalvu ovemvane asebenza kahle avame ukwakhiwa ngezinto ezihlala isikhathi eside, njengensimbi engagqwali noma ama-alloys angavamile, ukuze amelane nezinto ezibolayo noma ezilimazayo. ukusebenza kwetorque, okuvumela ukusebenza kahle nokuncipha kokuguga ezingxenyeni zamavalvu.Idizayini Ephephile Emlilweni: Amanye amavalvu emvemvane asebenza kahle aklanyelwe ukuhlangabezana nezindinganiso eziphephile emlilweni, anikeze isendlalelo esengeziwe sokuphepha uma kwenzeka kuba nezigameko zomlilo.Ikhono Lokucindezela Okuphezulu : Lawa ma-valve afanele izinhlelo zokusebenza ezidinga amandla okusingatha ingcindezi ephezulu.Lapho ukhetha i-valve uvemvane esebenza kahle, kubalulekile ukucabangela izici ezifana nokusetshenziswa okuqondile, izimo zokusebenza, ukuhambisana kwezinto, izindinganiso zemboni, nokucatshangelwa kwemvelo.Ukulinganisa kahle nokukhethwa kubalulekile ukuze kuqinisekiswe ukuthi i-valve ihlangabezana nezidingo zokusebenza zohlelo oluhlosiwe.
✧ Izici ze-High Performance Butterfly Valve
Amavalvu Evemvane Asebenza Kakhulu afaka izihlalo ezihlanganisiwe ze-polymer ezinobude obunganqunyelwe bempilo kanye nokumelana namakhemikhali aphezulu kakhulu - ambalwa amakhemikhali aziwa ukuthi athinta ama-polymer asekelwe ku-fluorocarbon, okwenza le mikhiqizo ihehe uma kufakwa amavalvu ezimbonini.Izinga layo lidlula elerabha noma amanye ama-polymer e-fluorocarbon ngokwengcindezi, izinga lokushisa kanye nokumelana nokugqokwa.
Umklamo jikelele we-valve
Isiqu se-High Performance Butterfly Valve siphakathi nendawo ezindizeni ezimbili.I-offset yokuqala ivela emgqeni ophakathi we-valve, futhi i-offset yesibili ivela emgqeni ophakathi wepayipi.Lokhu kubangela ukuthi i-disc ihlukane ngokuphelele nediski ngamadigri ambalwa kakhulu okusebenza kude nesihlalo.Bheka ukunikezwa ngezansi:
Umklamo wesihlalo
Ngokuphathelene nesihlalo, njengoba kushiwo ngaphambili, i-valve ene-rubber lined ivaliwe ngokucindezela emkhonweni wenjoloba.Idizayini yesihlalo se-Butterfly Valve G esebenza kahle kakhulu.Isibalo esingezansi sichaza ukuthi ukuhlala kuthinteka kanjani ezimeni ezi-3:
Ngemuva komhlangano: uma uhlangene ngaphandle kwengcindezi
Uma sihlanganiswe ngaphandle kwengcindezi, isihlalo sinikwa amandla yipuleti levemvane.Lokhu kuvumela ukuvaleka kwebhamuza kusuka ezingeni le-vacuum ngesilinganiso sokucindezela esiphezulu se-valve.
I-Axial pressure:
Iphrofayela ye-G-seat idala uphawu oluqinile njengoba ipuleti lihamba.Idizayini yokufaka inciphisa ukunyakaza kwesihlalo ngokweqile.
Ingcindezi ohlangothini lokufaka:
Ingcindezi iphendulela isihlalo phambili, ikhulise amandla okuvala.Ukufakwa endaweni egobayo kuklanyelwe ukuvumela ukuzungezisa izihlalo.Lesi isiqondiso sokukhweza esincanyelwayo.
Isihlalo se-High Performance Butterfly Valve sinomsebenzi wenkumbulo.Isihlalo sibuyela esimweni saso sasekuqaleni ngemva kokulayisha.Ikhono lesihlalo sokululama lichazwa ngezilinganiso zokuguquguquka okuhlala njalo kwesihlalo.I-deformation ephansi ehlala njalo isho ukuthi impahla inenkumbulo engcono - ayijwayele ukuguga unomphela lapho kufakwa umthwalo.Ngenxa yalokho, izilinganiso eziphansi zokuguquguquka ezihlala njalo zisho ukutholakala kwesihlalo okuthuthukisiwe kanye nesikhathi eside sokuphila sophawu.Lokhu kusho ukuvala uphawu okuthuthukisiwe ngaphansi kwengcindezi kanye nokuhamba ngebhayisikili okushisayo.I-Deformation ithintwa izinga lokushisa.
Ukupakishwa kwesiqu kanye nomklamo wokuzala
Iphuzu lokugcina lokuqhathanisa uphawu oluvimbela ukuvuza kwangaphandle endaweni ye-stem.
Njengoba ungabona ngezansi, ama-valve anerabha ane-stem seal elula kakhulu, engalungiseki.Idizayini isebenzisa i-stem bushing ukubeka maphakathi shaft kanye nezinkomishi ze-U zerabha ezi-2 ukuvala okuphakathi ukuze kuvinjelwe ukuvuza.
Akukho ukulungiswa okwenziwa endaweni evalekile, okusho ukuthi uma kuvuza, i-valve kufanele ikhishwe emgqeni futhi ilungiswe noma ishintshwe.Indawo ephansi ye-shaft ayinakho ukusekelwa kwe-stem, ngakho-ke uma izinhlayiya zithuthela endaweni engaphezulu noma ephansi ye-shaft, i-torque yokushayela iyakhuphuka, okuholela ekusebenzeni okunzima.
Amavaluvu Evemvane Asebenza Kakhulu aboniswe ngezansi aklanywe ngokupakishwa okulungiseka ngokuphelele (i-shaft seal) ukuze kuqinisekiswe impilo ende yesevisi futhi akukho ukuvuza kwangaphandle.Uma ukuvuza kwenzeka ngokuhamba kwesikhathi, i-valve ine-gland yokupakisha elungiseka ngokugcwele.Vula kuphela iringi yamantongomane ngesikhathi kuze kuphele ukuvuza.
✧ Izinzuzo ze-High Performance Butterfly Valve
Ngesikhathi sokuvula nokuvala i-valve yeglobu yensimbi eyenziwe ngomgunyathi, ngenxa yokuthi ukungqubuzana phakathi kwe-disc kanye nendawo yokuvala yomzimba we-valve kuncane kunaleyo ye-valve yesango, ayigugi.
I-stroke yokuvula noma yokuvala ye-valve stem imfushane kakhulu, futhi inomsebenzi wokusika othembeke kakhulu, futhi ngenxa yokuthi ukuguqulwa kwembobo yesihlalo se-valve kuhambisana nokushaywa kwe-valve disc, kulungele kakhulu ukulungiswa. wezinga lokugeleza.Ngakho-ke, lolu hlobo lwe-valve lufaneleka kakhulu ukunqunywa noma ukulawulwa nokudonsa.
