Kwi-severe-served chemical processing—ezifana ne-catalyst slurry loops, ii-delayed coking units, kunye ne-high-density polyethylene (HDPE) polymerization reactors—izihlalo ezithambileyo ze-polymeric okanye ze-elastomeric zibaluleke kakhulu. Izinto ezifakiweyo eziqhelekileyo ezifana ne-PTFE, i-RPTFE, okanye ne-reinforced PEEK zikhawuleza zithintelwe ngamandla atshabalalisayo e-abrasive catalyst fines, i-mechanical erosion, kunye ne-extreme thermal cycling. Xa izinto ezithambileyo ziwohloka, isiphumo sivela ngoko nangoko: ukuvuza kwepakeji, i-line bypass, kunye nokuvalwa kwezityalo okungalindelekanga.
Ukuqinisekisa ukusebenza koomatshini kunye nokuzahlula ngokupheleleyo kwiindawo ezinobungozi, iingcali ze-process automation kunye neenjineli zokuthembeka ziyayeka ukusebenzisa iivalvu zempahla eziqhelekileyo. Isisombululo sikwii-engineering eziphezulu.iivalvu zebhola ezihleli ngentsimbi.
At INKAMPANI YEVALVE YE-NSW (nswvalve.com), senza iinkonzo ezisebenza ngoxinzelelo oluphezulu nezinzimaiivalvu zebhola ezihleli ngentsimbiyenzelwe ukuphelisa iindlela eziqhelekileyo zokusilela kokukhukuliseka kunye nokubopha ubushushu ngelixa inika ukuvalwa okuqinileyo nokwamacala amabini.
1. I-Supersonic Metallurgy: Ii-HVOF Coating Mechanics zeeValve zeBhola eziHlaliswe ngeSinyithi
Ukuthembeka okusisiseko kwenkonzo enzimaiivalvu zebhola ezihleli ngentsimbiixhomekeke kukuthembeka kwebhondi kunye nokuqina komphezulu wengubo yobuso bayo. Endaweni yokuxhomekeka kwi-electroplating yendabuko,INKAMPANI YEVALVE YE-NSWizixhoboI-Oxygen-Fuel enesantya esiphezulu (i-HVOF)Ukutshiza ngobushushu. Le ndlela isebenzisa ii-carbide matrices eziphambili kwi-substrates ezine-alloy ephezulu, kuquka i-ASTM A351 CF8M, i-CF3M, kunye neentsimbi ezingenasici ze-Super Duplex.
Ngexesha lenkqubo yethu ye-HVOF, i-compound eqinileyo ifakwa kumjelo wokutsha oqhutywa yi-oksijini kunye ne-kerosene ephezulu. Amasuntswana akhawuleza aye kwisantya esiphezulu esidlulaIMach 3, iguqula amandla amakhulu e-kinetic abe yi-dense, ultra-low porosity ($< 0.5\%$) interlocking layer. Amandla e-mechanical bond avelayo adlula i-$10,000 \text{ psi}$ ($69 \text{ MPa}$), ukuqinisekisa ukuba i-hard coating yethuiivalvu zebhola ezihleli ngentsimbiayizukunyibilika xa i-hydrodynamic shear inamandla.
| I-Matrix yokugquma | Ii-Alloys zeSiseko esiPhambili | Uluhlu loBulukhuni obuNcinci | Ubushushu obuphezulu | Izicelo eziqhelekileyo |
|---|---|---|---|---|
| I-Tungsten Carbide (WC-Co-Cr) | I-Cobalt-Chromium-Nickel | 68 – 72 HRC | $750^\circ\text{F}$ ($400^\circ\text{C}$) | I-Catalyst Slurry, i-FCCU Slurry, ii-Slime Tailings |
| I-Chromium Carbide ($Cr_3C_2\text{-NiCr}$) | I-Nickel-Chromium | 56 - 62 HRC | $1500^\circ\text{F}$ ($815^\circ\text{C}$) | Ukucola okuLibazisekileyo, Ukuhlaziywa kweSisefo seMolekyuli |
| I-Stellite 6 / 12 | Isisombululo Esiqinileyo Esisekelwe kwiCobalt | 40 – 48 HRC | $1000^\circ\text{F}$ ($538^\circ\text{C}$) | Umoya oXinzelelo oluPhezulu, Amanzi okuPhelela eBoiler |
Ukhetho Lokugquma Oluchanekileyo Ngesicelo:
- I-Tungsten Carbide (WC-Co-Cr): Yenzelwe ngokukodwa ukukrala okukhulu kwamasuntswana ngaphakathi kwethuiivalvu zebhola ezihleli ngentsimbiI-matrix inika ubulukhuni obuncinci ukuya kuthi ga kwi72 HRC, esebenza njengesikrweqe esingenakugqobhozwa nxamnye nesenzo sokukhuhla ii-catalyst fines kunye ne-silica solids.
- I-Chromium Carbide ($Cr_3C_2\text{-NiCr}$): Yenzelwe imidiya yokuxoxisa eshushu kakhulu. Igcina uzinzo lwayo lwekristale ukuya kuthi ga kwi-$1500^\circ\text{F}$, ithintela ukuqhekeka kwe-thermal kunye nokukhula okuhlala kutshabalalisa imboni.iivalvu zebhola ezihleli ngentsimbingexesha loxinzelelo olukhawulezayo lobushushu.
2. Ukususa Ukuvuza Kwangasemva Nge-Mate-Lapping Mechanics
Ingcamango engaqhelekanga phakathi kwabayili beepayipi kukubaiivalvu zebhola ezihleli ngentsimbikufuneka ivumelane nokuqina kokutywina.INKAMPANI YEVALVE YE-NSWisusa isihlalo esingasemva esidlula kwiyunithi enye, ezinikeleyoIprotokholi ye-Mate-Lapping.
Endaweni yokuba izinto ezidibanisa ubukhulu becala zichasene nee-molds ezisemgangathweni, ibhola nganye nganye idityaniswa nesangqa sayo sesihlalo sesinyithi. Iingcali zisebenzisa inkqubo yoomatshini enamanqanaba amaninzi ene-media ecolekileyo yedayimani, igqibela kwi-abrasive damage.Intlama yegrit ye-1-micron.
Olu ngqamaniso luchanekileyo lufezekisa ibhendi yoqhagamshelwano eqhubekayo, engenasiphako ye-$360^\circ$. Ukulingana kwejometri okuphumayo kuhambelana nemigangatho ye-interferometry yebhendi yokukhanya, okuvumela i-NSWiivalvu zebhola ezihleli ngentsimbiukufezekisa rhoqoI-ISO 5208 Rate A kunye ne-API 598 zero-leakageukusebenza phantsi kovavanyo lwegesi olunoxinzelelo oluphezulu—oluzisa ukusebenza okuqinileyo njengebhamuza kuyilo lokuvalwa kwesinyithi olunzima.
3. Ulawulo lweDynamic Solids: Izihlalo zeScraper kunye nokuthobela ubushushu
Kwizicelo ezinzima ze-slurry okanye ze-polymer, ii-particles ezibambekileyo zinokuqhekeka phakathi kwebhola kunye nesihlalo ngexesha lokuguqulwa kwekota, okubangela amanqaku arhabaxa okanye ukubanjwa ngoomatshini. I-NSW isombulula olu buthathaka ngokulungiswa.Iprofayili yeSihlalo seScraperidibene nokulayisha kwangaphambili koomatshini okuguquguqukayo.

Iprofayili Yomphetho Wokuzicoca
Umlebe oyintloko wokutywina wesangqa sethu sentsimbi unemiphetho ebukhali, eyenziwe ngomatshini yejometri. Njengoko ibhola isiya kwindawo evaliweyo, le profayili isebenza njengesikrweli somatshini, isusa isikali, iidiphozithi zekristale, kunye nokwakheka kwepolymer enamathelayo ngaphambi kokuba zingene ebusweni bokutywina besangqa sethu.iivalvu zebhola ezihleli ngentsimbi.
Imbuyekezo Yokwandiswa Kobushushu
Iinkqubo zeekhemikhali ezinobushushu obuphezulu zibeka umngcipheko wokubopha ubushushu. Xa i-process media inyuka kubushushu, izinga lokwandiswa kwebhola linokudlula umzimba wevalvu, livale ivalvu endaweni yayo.
I-NSW iyawuphepha lo mba ngokufaka izinto ezisebenza nzima nezimelana nokugqwalaImithombo yamaza ye-Inconel 718 Bellevillengasemva kwendibano yesihlalo. Olu lwakhiwo lugcina isitywina esikhuselekileyo esinoxinzelelo oluphantsi ngelixa lubonelela ngokuguquguquka koomatshini okufunekayo ukufunxa ukwanda kobushushu.
4. Ukuthobela iMithetho yokusingqongileyo: Ukupakisha okuphantsi kwe-E kunye noKhuseleko loMlilo
Imiyalelo yokusingqongileyo kulo lonke elaseMntla Melika ifuna ukuba kunganyamezelwa ukukhutshwa komoya ongcolileyo. Iziqu zeevalvu zezona zixhaphakileyo zokwaphulwa kwe-EPA LDAR (Ukufumanisa nokuLungisa ukuVuleka).
Ukuthintela Ukukhutshwa Komoya Ongcolileyo Ngababaleki: NSWiivalvu zebhola ezihleli ngentsimbifaka indibano yokupakisha isiqu elayishwe bukhoma eqinisekisiweyo ukubaI-API 641kwiivalvu zekota-turn, kusetyenziswaI-API 622Iiseti zokupakisha zegrafiti eziguquguqukayo ezenziwe nge-die-formed. Umthwalo oxinzelelweyo uhlala ugcinwa nge-Belleville spring washers, nto leyo egcina ukuvuza kwesiqu kuphantsi kwayo.100 ppmvngexesha lemijikelo yobushushu ende.
Ukhuseleko Lomlilo Oluqhelekileyo: Iqinisekiswe ngokupheleleyo ukubaI-API 607 kunye ne-API 6FAIikhrayitheriya. Ngenxa yokuba umda woxinzelelo, izinto zokuvala, kunye nezitywino zesiqu zenziwe kuphela ngesinyithi esomeleleyo esiqinileyo kunye negrafiti enoxinano oluphezulu, ivalvu igcina ukwahlulwa ngokupheleleyo kwesakhiwo ngexesha lokuvezwa kumlilo we-hydrocarbon ($1400^\circ\text{F}$ ukuya kwi-$1800^\circ\text{F}$).
Isikhokelo seNkcazelo yokuThengwa koBunjineli
