Ekucutshungulweni kwamakhemikhali okusebenza kanzima—njengezihibe ze-catalyst slurry, amayunithi e-coking abambezelekile, kanye nama-reactor e-polyethylene (HDPE) polymerization aphezulu—izihlalo ezithambile ze-polymeric noma ze-elastomeric ziyisibopho esibalulekile. Izinto ezijwayelekile ezifana ne-PTFE, i-RPTFE, noma ngisho ne-PEEK eqinisiwe zisheshe zinqotshwe amandla abhubhisayo ama-catalyst fines abrasive, ukuguguleka komshini, kanye nokujikeleza kokushisa okukhulu. Lapho izinto ezithambile ziwohloka, umphumela uba ngokushesha: ukuvuza kokupakisha, i-line bypass, kanye nokuvalwa kwezitshalo okungalindelekile.
Ukuqinisekisa ukusebenza kwesikhathi somshini kanye nokuhlukaniswa ngokuphelele ezindaweni ezinonya, ochwepheshe bezinqubo zokwenza izinto ngokuzenzakalela kanye nonjiniyela bokuthembeka bayayeka ukusebenzisa ama-valve ezimpahla ajwayelekile. Isixazululo sisekuklanyweni okunobunjiniyela obuphezulu.amavalvu ebhola ahleli ngensimbi.
At INKAMPANI YAMAVALVU E-NSW (nswvalve.com), sakha insizakalo enamandla futhi enamandla kakhuluamavalvu ebhola ahleli ngensimbieklanyelwe ukuqeda izindlela ezivamile zokwehluleka kokuguguleka kanye nokubopha ukushisa ngenkathi ihlinzeka ngokuvala okuqinile nokuqondisayo.
1. I-Supersonic Metallurgy: Imishini Yokumboza ye-HVOF Yama-Ball Valve Ahlala Ngensimbi
Ukwethembeka okuyisisekelo kwensizakalo enzimaamavalvu ebhola ahleli ngensimbikunqunywa ubuqotho besibopho kanye nokuqina kobuso bezingubo zayo zobuso. Esikhundleni sokuthembela ekufakweni kwe-electroplating yendabuko,INKAMPANI YAMAVALVU E-NSWizinsizaI-Oxygen-Fuel Esheshayo Kakhulu (i-HVOF)Ukufutha ngokushisa. Le ndlela isebenzisa ama-carbide matrices athuthukile kuma-substrates ane-alloy ephezulu, kufaka phakathi i-ASTM A351 CF8M, CF3M, kanye ne-Super Duplex stainless steels.
Ngesikhathi senqubo yethu ye-HVOF, inhlanganisela eqinile ifakwa emseleni wokushisa oqhutshwa yi-oxygen kanye ne-parafini yezinga eliphezulu. Izinhlayiya zishesha zibe yisivinini esingaphezu kwe-supersonicI-Mach 3, iguqula amandla amakhulu e-kinetic abe ungqimba oluhlanganisiwe oluqinile, oluphansi kakhulu ($< 0.5\%$). Amandla esibopho somshini aphumelayo adlula u-$10,000 \text{ psi}$ ($69 \text{ MPa}$), okuqinisekisa ukuthi uqweqwe oluqinile lwe-amavalvu ebhola ahleli ngensimbingeke ihlukane ngaphansi kokugunda okukhulu kwe-hydrodynamic.
| I-Matrix Yokumboza | Ama-Alloys Ayisisekelo Esiyinhloko | Ububanzi Bokuqina Okuncane | Izinga lokushisa eliphezulu | Izicelo Ezijwayelekile |
|---|---|---|---|---|
| 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, i-Slime Tailings |
| I-Chromium Carbide ($Cr_3C_2\text{-NiCr}$) | I-Nickel-Chromium | 56 – 62 HRC | $1500^\circ\text{F}$ ($815^\circ\text{C}$) | Ukupheka Okulibazisekile, Ukuvuselelwa Kwesihlungo Sama-Molecular |
| I-Stellite 6/12 | Isixazululo Esiqinile Se-Cobalt-Base | 40 – 48 HRC | $1000^\circ\text{F}$ ($538^\circ\text{C}$) | Umusi Onomfutho Ophezulu, Amanzi Okuphakelwa Kwebhoyila |
Ukukhetha Ukugqoka Okuqondene Nesicelo:
- I-Tungsten Carbide (WC-Co-Cr): Yakhelwe ngokukhethekile ukuklwebheka kwezinhlayiya ezinzima ngaphakathi kwethuamavalvu ebhola ahleli ngensimbiI-matrix inikeza ubulukhuni obuncane obufika ku-72 HRC, esebenza njengesivikelo esingenakunqotshwa ngokumelene nesenzo sokuhlikihla sezinto ezibangela ukuvuvukala kanye nezinto eziqinile ze-silica.
- I-Chromium Carbide ($Cr_3C_2\text{-NiCr}$): Yenzelwe imidiya yokushisa okuphezulu yokuxilisa. Igcina ukuzinza kwayo kwesakhiwo okukristalu kuze kufike ku-$1500^\circ\text{F}$, ivimbela ukuqhekeka okuncane kokushisa kanye nokukhula okuvame ukulimaza izimboni.amavalvu ebhola ahleli ngensimbingesikhathi sokushaqeka okusheshayo kokushisa.
2. Ukuqeda Ukuvuza Kwangemuva Nge-Mate-Lapping Mechanics
Umbono ongalungile ovame ukuvela phakathi kwabaklami bamapayipi ukuthiamavalvu ebhola ahleli ngensimbikumele kube lula ukuvala ukuqina.INKAMPANI YAMAVALVU E-NSWiqeda ukudlula kwesihlalo sangemuva ngeyunithi eyodwa, ezinikeleIphrothokholi Yokugoqa I-Mate.
Esikhundleni sezingxenye ezihlanganisa ubukhulu obufanayo ngokumelene nezimonyo ezijwayelekile, ibhola ngalinye lihambisana nendandatho yalo yesihlalo sensimbi ethile. Ochwepheshe basebenzisa inqubo yomshini enezigaba eziningi enemidiya encibilikisa idayimane kancane kancane, ephetha kuze kubeI-grit paste engu-1-micron.
Lokhu kufanisa okunembile kufeza ibhendi yokuxhumana eqhubekayo, engenaphutha engu-$360^\circ$. Ukufana kwejometri okuphumelayo kufanelana nezindinganiso ze-interferometry yebhendi yokukhanya, okuvumela i-NSWamavalvu ebhola ahleli ngensimbiukufeza njaloIsilinganiso se-ISO 5208 A kanye ne-API 598 sokuvuza okungenazihibeukusebenza ngaphansi kokuhlolwa kwegesi okunomfutho ophezulu—okuletha ukusebenza okuqinile njengamabhamuza kumklamo wokuvala insimbi onzima.
3. Ukuphathwa Kwezinto Eziqinile Eziguquguqukayo: Izihlalo Ezisikekayo kanye Nokuhambisana Nokushisa
Ezisetshenzisweni ezisindayo ze-slurry noma ze-polymer, izinhlayiya ezibambekile zingahlukana phakathi kwebhola nesihlalo ngesikhathi sokushintsha kwekota, okubangela ukugoba okujulile noma ukubanjwa ngomshini. I-NSW ixazulula lobu buthakathaka ngokusebenzisa indlela elungiselelwe kahle.Iphrofayili Yesihlalo Esikhafulelayokubhangqwe nokulayisha kwangaphambili kwemishini okuguquguqukayo.

Iphrofayili Yomphetho Wokuzihlanza
Umlomo oyinhloko wokuvala wendandatho yethu yesihlalo sensimbi unomphetho obukhali, ohlotshiswe ngomshini. Njengoba ibhola lihamba liye endaweni evaliwe, le phrofayili isebenza njengesikrweli somshini, isusa isikali, ama-crystalline deposits, kanye nokwakheka kwe-polymer okunamathelayo ngaphambi kokuba kungene ebusweni bokuvala be-amavalvu ebhola ahleli ngensimbi.
Isinxephezelo Sokwanda Kokushisa
Izinqubo zamakhemikhali ezishisa kakhulu ziletha ingozi yokubopha ukushisa. Lapho imidiya yenqubo ikhuphuka ekushiseni, izinga lokunwebeka kwebhola lingadlula umzimba wevalvu, livale ivalvu endaweni yayo.
I-NSW iyayigwema le nkinga ngokufaka izinto ezisindayo, ezingagqwaliIziphethu zamagagasi ze-Inconel 718 Bellevillengemuva kwesihlalo. Lokhu kulungiselelwa kugcina uphawu oluqinile oluphansi ngenkathi kunikeza ukuguquguquka komshini okudingekayo ukuze kuthathwe ukwanda kokushisa.
4. Ukuthobela Imithetho Yezemvelo: Ukupakisha Okuphansi kanye Nokuphepha Komlilo
Imithetho yezemvelo kulo lonke elaseNyakatho Melika idinga ukuthi kungabekezeleleki ukukhishwa kwegesi okusabalele. Iziqu zamavalvu ziwumthombo ovame kakhulu wokwephulwa kwe-EPA LDAR (Ukutholwa Nokulungiswa Kokuvuza).
Ukuvimbela Ukukhishwa Kwegesi Okubangelwa Ababaleki: NSWamavalvu ebhola ahleli ngensimbifaka i-stem packing assembly elayishwe bukhoma eqinisekisiwe ukuthiI-API 641ama-valve ajika ngekota, kusetshenziswaI-API 622Amasethi okupakisha e-graphite aguquguqukayo akhiwe ngendlela yokufa. Umthwalo ocindezelayo uhlala ugcinwa ngemishini yokuwasha yasentwasahlobo yaseBelleville, okugcina ngempumelelo ukuvuza kwesiqu ngaphansi100 ppmvngesikhathi sokujikeleza kokushisa okweluliwe.
Ukuphepha Komlilo Okungokwemvelo: Kuqinisekiswe ngokugcwele ukuthiI-API 607 kanye ne-API 6FAimigomo. Ngenxa yokuthi umngcele wokucindezela, izinto zokuvala, kanye nezimpawu zesiqu kuqukethe kuphela insimbi eqinile eqinile kanye ne-graphite enobukhulu obuphezulu, ivalvu igcina ukuhlukaniswa okuphelele kwesakhiwo ngesikhathi sokuchayeka emcimbini womlilo we-hydrocarbon ($1400^\circ\text{F}$ to $1800^\circ\text{F}$).
Umhlahlandlela Wokucaciswa Kokuthengwa Kobunjiniyela
Kumashidi edatha ephrojekthi ezayo, imininingwane yezinto zokufaka amapayipi (i-PMS), noma uhlu lwabathengisi, isevisi enzimaamavalvu ebhola ahleli ngensimbiuchungechunge oluvela ku-INKAMPANI YAMAVALVU E-NSWifaka amapharamitha okuklama ajwayelekile alandelayo:
