Ukugqwala kungenye yezinto ezibalulekile ezibangelauvemvane valve umonakalo.Kuuvemvane valve isivikelo,uvemvane valve ukuvikela ukugqwala kuyindaba ebalulekile okufanele icatshangelwe.Okwensimbiuvemvane valves, ukwelashwa kokumboza phezulu kuyindlela engcono kakhulu yokuvikela engabizi kakhulu.
Indima yeinsimbiuvemvane valve enamathela ebusweni
01. Ukuvikela
Ngemuva kokuthi indawo yensimbi ihlanganiswe ngopende, indawo yensimbi ihlukanisiwe nemvelo.Lo mphumela wokuvikela ungabizwa ngokuthi umphumela wokuvikela.Kodwa kufanele kuphawulwe ukuthi ungqimba oluncane lukapende alukwazi ukudlala indima yokuvikela ngokuphelele.Ngenxa yokuthi i-polymer ephakeme inomoya othile wokungena komoya, lapho ukumboza kuncane kakhulu, izimbotshana zayo zesakhiwo zivumela ama-molecule amanzi nomoya-mpilo ukuba adlule ngokukhululekile.Okuvalwe kahleuvemvane valves anezidingo eziqinile kugqinsi lwe-epoxy coating ngaphezulu.Kungabonakala ukuthi ezimbotsheni eziningi inani likhulu kunobuso bensimbi obungafakiwe.Ukuze kuthuthukiswe ukungakwazi ukugqwala kwe-coating, i-anti-corrosion coating kufanele isebenzise into eyenza ifilimu ene-air permeability ephansi kanye nesigcwalisi esiqinile esinempahla enkulu yokuvikela, futhi ngesikhathi esifanayo, inani lezendlalelo zokugqoka kufanele lenyuke. ukuze i-coating ingafinyelela ubukhulu obuthile futhi ibe minyene futhi ingabi nama-porous.
02. Ukuvimbela ukugqwala
Ngokuphendula izingxenye zangaphakathi zokugqoka ngensimbi, indawo yensimbi idluliswa noma into evikelayo ikhiqizwa ukuze kuthuthukiswe umphumela wokuvikela we-coating.uvemvane valvesesetshenziselwa izidingo ezikhethekile kufanele inake ukwakheka kopende ukugwema imiphumela emibi kakhulu.Ngaphezu kwalokho, i-cast steeluvemvane valve esetshenziswa epayipini likawoyela, imikhiqizo yokucekela phansi ekhiqizwa ngaphansi kokusebenza kwamanye amafutha kanye nesenzo sokomiswa kwezinsipho zensimbi nakho kungadlala indima ye-organic corrosion inhibitors.
03. Ukuvikelwa kwe-electrochemical
Ukugqwala kwe-electrochemical ngaphansi kwefilimu kwenzeka lapho i-dielectric permeable coating ihlangana nendawo yensimbi.Sebenzisa izinsimbi ezinomsebenzi ophezulu kune-ayoni njengezigcwalisi ezimbotsheni, njenge-zinc.Izodlala indima yokuvikela ye-anode yomhlatshelo, futhi imikhiqizo yokugqwala ye-zinc iyisisekelo se-zinc chloride ne-zinc carbonate, ezovala igebe le-membrane futhi yenze ulwelwesi luqine, okunciphisa kakhulu ukugqwala futhi kwandise impilo yesevisi ye-membrane.uvemvane valve.
Izingubo ezivame ukusetshenziswa zensimbiuvemvane valves
01.uvemvane valve umzimba we-epoxy resin coating
Inezici ezilandelayo:
Ukumelana nokugqwala
Imigoqo yensimbi ene-epoxy-coated inokumelana nokugqwala okuhle, futhi amandla ebhondi anokhonkolo ancipha kakhulu.Ifanele izimo zezimboni ezindaweni ezinomswakama noma imidiya enolaka.
ukunamathela okuqinile
Ukuba khona kwe-polar hydroxyl kanye nebhondi ye-ether etholakala ochungechungeni lwamangqamuzana e-epoxy resins kuyenza inamathele kakhulu ezintweni ezahlukahlukene.I-epoxy resin ine-shrinkage ephansi ngesikhathi sokwelashwa, futhi ukucindezeleka kwangaphakathi okukhiqizwa kuncane, futhi ukumbozwa kwendawo yokuvikela akulula ukuwa nokuhluleka.
Izakhiwo zikagesi
Uhlelo olulashiwe lwe-epoxy resin luyinto enhle kakhulu yokuvikela enezici eziphezulu ze-dielectric, ukumelana nokuvuza kwendawo kanye nokumelana kwe-arc.
Ukumelana nesikhunta
Amasistimu e-epoxy aphulukisiwe amelana nesikhunta esiningi futhi angasetshenziswa ezimeni ezishisayo ezishisayo.
02.uvemvane valve ipuleti enayiloni plate impahla
Amashidi enayiloni amelana kakhulu nokugqwala futhi asetshenziswe ngempumelelo ezinhlelweni eziningi ezifana namanzi, udaka, ukudla, kanye nokukhipha usawoti emanzini.
ucansi lwangaphandle
Ibhodi enayiloni enamathelayo ingaphumelela ekuhlolweni kwesifutho sikasawoti, futhi ukumboza akuzange kuxebuke ngemva kokucwiliswa emanzini olwandle iminyaka engaphezu kwengu-25, ngakho akukho ukugqwala ezingxenyeni zensimbi.
ukumelana nemihuzuko
Inokumelana nokulimala okuhle kakhulu.
ukumelana nomthelela
Alukho uphawu lokuxebuka ngaphansi komthelela onamandla.
