Kugwiritsa ntchito valavu yayikulu yolowera mpweya wagulugufe m'mavavu ogulitsa mafakitale

Kugwiritsa ntchito valavu yagulugufe wamkulu wolowera mpweya m'mavavu aku mafakitale (1) Lumikizani valavu ndi ulusi. KULUMIKIZANA kumeneku KUMACHITIKA KABWINO NDI KUCHITA ALVE INLET NDIPO NTCHITO YOGWIRITSA NTCHITO IKUTHA NDI ULULU WA CHIPOSI WOTSATIRA KAPENA WOWONONGA ZIMENE UNGALUMIKIZWE NDI ZOPHUNZITSIRA ZOPHUNZITSIRA ZINTHU KAPENA MIzere. Chifukwa cha kuthekera kwa njira zazikulu zotayikira panjira iyi, mayendedwewa amatha kutsekedwa ndi sealant, tepi yosindikiza, kapena kulongedza. Ngati zakuthupi ZA valavu thupi akhoza welded, koma coefficient wa kukula ndi osiyana kwambiri, kapena osiyanasiyana osiyanasiyana kutentha ntchito ndi lalikulu, kugwirizana ulusi ayenera kukhala uchi losindikizidwa kuwotcherera. Kulumikizana kwa ulusi wa vavu ndi makamaka meridian mwadzina mu valavu 50mm zotsatirazi. Ngati kukula kwake kuli kwakukulu kwambiri, kumakhala kovuta kwambiri kukhazikitsa ndi kusindikiza mgwirizanowo. Kuti athandizire kuyika ndi kuchotsedwa kwa ma valve opangidwa ndi ulusi, zolumikizira zimapezeka pamalo oyenera pamapaipi. Mavavu ofikira 50mm kukula mwadzina amatha kugwiritsa ntchito cholumikizira cha manja ngati cholumikizira, chokhala ndi ulusi wolumikiza magawo awiri a olowa. (2) Valavu yolumikizana ndi flange. Ma valve a Flanged ndi osavuta kukhazikitsa ndikuchotsa. Koma iwo ndi ochulukirapo kuposa ma valve opangidwa ndi ulusi, ndipo nawonso ndi okwera mtengo. Choncho, ndi oyenera kugwirizana chitoliro zosiyanasiyana kukula ndi mavuto. Komabe, kutentha kupitirira madigiri 350, chifukwa cha kumasulidwa kwa ma bolts, gaskets ndi flanges, zomwe zimachepetsanso kwambiri katundu pazitsulo, kutayikira kungathe kuchitika kwa kugwirizana kwambiri kwa flange. (3) Wonjezerani valavu. Kulumikizana kumeneku ndi koyenera kwa mitundu yonse ya kupanikizika ndi kutentha, ndipo ndikodalirika kuposa kugwirizanitsa flanged pamene kugwiritsidwa ntchito pansi pa zovuta. Koma kuwotcherera valavu disassembly ndi reinstallation n'kovuta kwambiri, choncho ntchito yake ndi malire kuti kawirikawiri akhoza kuthamanga modalirika kwa nthawi yaitali, kapena ntchito mikhalidwe yotsegula, nthawi kutentha kwambiri. Monga malo opangira magetsi otentha, projekiti yamphamvu ya nyukiliya, pulojekiti ya ethylene paipi. Ma valve otsekemera okhala ndi mainchesi mpaka 50mm nthawi zambiri amakhala ndi ma jacks owotcherera kuti agwire chitoliro kumapeto kwa katundu. Chifukwa kuwotcherera zitsulo kumapanga kusiyana pakati pa socket ndi payipi, zomwe zingapangitse kusiyana kuti kuwonongeke ndi zofalitsa zina, ndipo kugwedezeka kwa payipi kumapangitsa kuti gawo lolumikizana litope, motero kugwiritsa ntchito kuwotcherera zitsulo kumakhala kochepa. Mu m'mimba mwake mwadzina ndi lalikulu, ntchito zikhalidwe Mumakonda, kutentha kwambiri, valavu thupi zambiri utenga poyambira kuwotcherera poyambira, pa nthawi yomweyo, kuwotcherera olowa ali zofunika choyambirira, ayenera kusankha amphamvu luso kuwotcherera kuti amalize ntchito Large m'mimba mwake mpweya wabwino. valavu butterfly pa ntchito mavavu mafakitale Pakali pano dziko lathu mafakitale osiyanasiyana valavu zitsulo, valavu chimagwiritsidwa ntchito kupanga valavu zitsulo ntchito zaka mazana a mbiri, amene kudzera kusintha kapangidwe ndi zinthu, koma ndi zofooka zake, zipangizo zitsulo ndi mochulukira sangathe agwirizane ndi zoipa ntchito mikhalidwe, chotero kuvala amphamvu mkulu ndi dzimbiri. Zowonetsedwa makamaka mu moyo waufupi wautumiki, kutayikira kudakhudza kwambiri kukhazikika kwa magwiridwe antchito. Valavu yachitsulo yachikhalidwe ikufunika mwachangu kukonzanso zinthu, kupanga ndi kupanga. Pakalipano, valavu yomwe imagwiritsidwa ntchito kwambiri popanga mafakitale osiyanasiyana m'dziko lathu ndi valve yachitsulo. Kugwiritsiridwa ntchito kwa valve yachitsulo kwadutsa zaka zana zapitazo. Ngakhale zakonzedwa bwino ndi kapangidwe kake ndi zida, sizingakwaniritse zosowa zamavalidwe apamwamba, dzimbiri lamphamvu ndi zovuta zina zogwirira ntchito. Zowonetsedwa makamaka mu moyo waufupi wautumiki, kutayikira kudakhudza kwambiri kukhazikika kwa magwiridwe antchito. Valavu yachitsulo yachikhalidwe ikufunika mwachangu kukonzanso zinthu, kupanga ndi kupanga. Zida za ceramic zapamwamba, monga zinthu zatsopano m'zaka za zana la 21, zakhala zikutengedwa mozama ndi ogwira ntchito asayansi ochulukirachulukira. Ndiwopanga molimba mtima komanso wopindulitsa kugwiritsa ntchito ma valve a mafakitale. Zida za ceramic zimakhala ndi mapindikidwe ochepa kwambiri komanso mphamvu zomangira zapamwamba kuposa zitsulo. Nthawi zambiri, ma crystalline ionic radius ya zida za ceramic ndi yaying'ono, ndipo mtengo wamagetsi wa ionic ndi wokwera, ndipo nambala yolumikizira ndi yayikulu. Zinthu izi zimatsimikizira kulimba kwamphamvu, mphamvu zopondereza, zotanuka modulus ndi kuuma kwa zida za ceramic ndizokwera kwambiri. Ceramic palokha Komabe, "chimaona" ndi zovuta processing malire kukula kwake kwa ntchito zaka makumi angapo, chifukwa martensitic gawo kusintha toughening luso, gulu la zinthu sayansi ndi luso ndi chitukuko ndi patsogolo mfundo ya nanometer ziwiya zadothi zopangidwa mbiya ndi zadothi. "brittle" ali ndi * * kuti asinthe, kulimba ndi mphamvu zasinthidwa kwambiri, ndikukulitsa kuchuluka kwa ntchito. Valavu ya ceramic yosamva kuvala imagwiritsidwa ntchito kwambiri pamagetsi, mafuta, mafakitale amafuta, zitsulo, migodi, zimbudzi ndi minda ina yamafakitale, makamaka poyang'anizana ndi kuvala kwakukulu, dzimbiri zamphamvu, kutentha kwambiri, kuthamanga kwambiri ndi zovuta zina zogwirira ntchito, komanso ikuwonetsa magwiridwe ake abwino kwambiri. Ikhoza kukumana ndi kugwiritsidwa ntchito kwa kuvala kwakukulu, malo owononga kwambiri, makamaka mawonekedwe apamwamba ndi moyo wautali wautumiki, chiŵerengero cha mtengo wake ndi chabwino kwambiri kuposa ma valve ena achitsulo ofanana. Ndi chitukuko mosalekeza ndi kupita patsogolo kwa sayansi ndi luso, ceramic zipangizo kuchokera chiphunzitso, akamaumba, processing ndi msonkhano luso ndi mbali zina za luso ndi okhwima ndi wathunthu, valavu ceramic ndi ntchito zake zabwino kwambiri kuti kuzindikira anthu mu makampani. . Chidziwitso chochita bwino popanga ma valve a ceramic chitha kugwiritsidwanso ntchito kumadera apamwamba kwambiri aukadaulo.
