Ma Valves a Mpira Opindika ndi Ulusi: Malangizo Osankha

Kusankha pakati pavalavu ya mpira wopindikandivalavu ya mpira yolumikizidwaNdi chisankho chofunikira kwambiri chaukadaulo chomwe chimapitirira kuposa mtundu wolumikizirana. Chimakhudza mwachindunji umphumphu, chitetezo, moyo wokonza, ndi mtengo wonse wa makina anu opachikira mapaipi. Ngakhale kuti mtengo ndi kuphweka nthawi zambiri zimakhala zoyambira, kumvetsetsa bwino momwe magwiridwe antchito amagwirira ntchito ndikofunikira kwambiri kuti musankhe bwino.

Bukuli likufotokoza zambiri zokhudza kufananiza kwa magetsi, zomwe zingakuthandizeni kusankha njira yoyenera yolumikizira magetsi ndi mphamvu zomwe mukufuna, kukonza, ndi momwe mungagwiritsire ntchito.

Filosofi Yopangira Kapangidwe Kachikulu: Yokhazikika vs Yogwiritsidwa Ntchito

Kusiyanaku kumachokera ku moyo womwe ukufunidwa komanso kuthekera kwa ntchito ya dongosololi.

Ma Valves a Mpira Olumikizidwa: Yankho Lalifupi, Losatha

Avalavu ya mpira yolumikizidwaimagwiritsa ntchito ulusi wa National Pipe Taper (NPT) kuti ikulume mwachindunji paipi. Kapangidwe ka ulusi wocheperako kamapanga wedge yochokera ku chitsulo kupita ku chitsulo yomwe, mothandizidwa ndi chosindikizira, imaletsa kutuluka kwa madzi. Malingaliro a kapangidwe kameneka amalimbikitsa ulusi wocheperako, wotsika mtengo, komansomalo okhazikika kwambirikumene kusweka sikuyembekezeredwa.

Ma Vavu a Mpira Wopindika: Yankho Labwino Kwambiri, Lothandiza

Avalavu ya mpira wopindikaIli ndi ma flange opangidwa ndi makina omwe amamangiriridwa ku ma flange ofanana ndi mapaipi, ndi gasket yopanikizidwa pakati pawo kuti apange chisindikizo. Kapangidwe kameneka kamapangidwiramachitidwe odalirika kwambiri, otheka kugwiritsidwa ntchito, komanso okhazikikaZimalola kuyika, kuchotsa, ndi kuyang'ana mosavuta popanda kusintha makina, zomwe zimapangitsa kuti zikhale zofunikira kwambiri pa ntchito zofunika kwambiri.

Kuyerekeza kwa Kusanthula: Kugwira Ntchito Pansi pa Kupanikizika

Mndandanda wosavuta wa zabwino ndi zoyipa sikokwanira. Nayi kusanthula kochokera ku data kwa zinthu zofunika kwambiri pakugwira ntchito.

1. Kutha kwa Kupanikizika ndi Kutentha

• Kulumikizana Kokhala ndi Ulusi: Ulusiwo ndi malo omwe angathe kulephera kugwira ntchito chifukwa cha kupsinjika. Umatha kusweka mosavuta chifukwa cha kupsinjika ndipo umatha kutuluka madzi chifukwa cha kutentha kwambiri. Ndiwoyenera kwambiri kugwiritsa ntchitoMavoti a Class 800 ndi pansi pake, nthawi zambiri mu mapulogalamu omwe ali pansi pa200-300 PSI.
• Kulumikizana Kopanda Flanged: Kulumikizana kolumikizidwa kumagawa katundu mofanana, ndipo chisindikizo cha gasket choyang'anizana ndi nkhope ndi cholimba kwambiri. Chopangidwa kuti chigwirizane ndi magulu opanikizika ofanana (ANSI Class 150, 300, 600, 900, 1500, 2500), mavavu opindika amatha kuthana ndi kupsinjika kopitilira 1000 PSI ndi madzi otentha kwambiri.

2. Kukhazikitsa, Kukonza, ndi Mtengo Wonse wa Uwini (TCO)

Valavu Yolumikizidwa TCO:

• Kukhazikitsa:Kukhazikitsa koyambirira mwachangu; kumafuna njira yotsekera ndi njira yoyenera yopangira ulusi.
• Kukonza:Vuto lalikulu. Kuchotsa valavu nthawi zambiri kumafuna kutsekereza valavu kuchokera pa chitoliro, zomwe sizingatheke chifukwa cha dzimbiri kapena kukhazikika kwa makina, zomwe zimapangitsa kuti mapaipi azidula kwambiri.
• TCO:Mtengo woyambira wotsika, koma kuthekera kokhala ndi ndalama zambiri zosamalira kwa nthawi yayitali.

Valavu Yopindika TCO:

• Kukhazikitsa:Zovuta kwambiri; zimafuna kusankha bwino gasket, kutsatizana kwa bolt, ndi mphamvu ya torque.
• Kukonza:Chosafanana. Vavu ikhoza kutsegulidwa ndikukwezedwa mwachindunji kuti igwiritsidwe ntchito, kusinthidwa, kapena kuyang'aniridwa, zomwe zimachepetsa nthawi yogwira ntchito kwa makina.
• TCO:Ndalama zoyambira zambiri (ma valavu, ma gasket, mabolts), koma zimachepetsa kwambiri ndalama zosamalira nthawi zonse komanso nthawi yogwira ntchito m'makina ofunikira.

3. Kukhulupirika kwa Dongosolo ndi Kuyenerera kwa Kagwiritsidwe Ntchito

Ma Valves Olumikizidwa mu Excel Mu:

• Kukula: Mapaipi ang'onoang'ono obowola (**)

Ma Valves Olumikizidwa mu Excel Mu:

• Kukula: Mapaipi ang'onoang'ono obowola (mainchesi awiri ndi pansi).
• Kugwiritsa Ntchito: Mapaipi a m'nyumba, HVAC, mizere ya madzi/mpweya yotsika mphamvu, zida za OEM, ndi makina opangira mankhwala komwe malo ndi ochepa.
• Malo: Makina okhazikika omwe ali ndi kugwedezeka kochepa komanso kutentha pang'ono.

Ma valve opangidwa ndi flange ndi ofunikira kwambiri pa:

• Kukula: mainchesi awiri kapena kupitirira apo (kwachizolowezi), ngakhale kuti nthawi zambiri amagwiritsidwa ntchito mpaka 1/2″ pa ntchito yofunika kwambiri.
• Kugwiritsa Ntchito: Kupanga Mafuta ndi Gasi, kukonza mankhwala, kupanga magetsi, main oteteza moto, makina a nthunzi, ndi njira iliyonse yokhala ndi zinthu zoopsa.
• Malo: Machitidwe omwe ali ndi kugwedezeka kwakukulu, kuthamanga kwa mphamvu, kutentha kwakukulu, kapena kufunikira kudzipatula nthawi zonse.

Matrix ya Zisankho: Kusankha Kulumikizana Koyenera

Kupitilira Zoyambira: Zofunika Kuganizira Zosankha

• Kusankha Gasket: Pa ma valve opindika, gasket ndi yofunika kwambiri kugwiritsidwa ntchito. Zipangizo (monga EPDM, PTFE, Graphite) ziyenera kugwirizana ndi madzi, kutentha, ndi kupanikizika.
• Kukhazikitsa Koyenera: Ulusi wa NPT uyenera kutsekedwa bwino ndi ulusi wopangidwa ndi ulusi kapena tepi. Ma flanged joints ayenera kumangidwa pogwiritsa ntchito njira yolumikizirana kuti zitsimikizire kuti gasket ikugwirizana bwino ndikuletsa kutuluka kwa madzi.
• Kugwirizana kwa Zinthu: Onetsetsani kuti zinthu za valavu (WCB, CF8M, ndi zina zotero) ndi zokongoletsa zikugwirizana ndi madzi anu kuti mupewe dzimbiri la galvanic kapena kuwonongeka kwa mankhwala.

Kutsiliza: Funso la Filosofi Yadongosolo

Mkangano wotsutsana ndi wotsutsana si wokhudza chomwe chili chabwino, koma chomwe chili choyenera nzeru za dongosolo lanu.

• Sankhani valavu ya mpira yokhala ndi ulusi kuti ikhale yotsika mtengo, yaying'ono, komanso yokhazikika m'mautumiki otsika mpaka apakati.
• Sankhani valavu ya mpira yozungulira kuti igwiritsidwe ntchito kwambiri, yofunikira, kapena yosamalira kwambiri komwe kukhulupirika kwa dongosolo, chitetezo, ndi kusinthasintha kwa magwiridwe antchito ndizofunikira kwambiri.

Ku NSW Valve, timapereka zambiri osati ma valve okha; timapereka ukatswiri. Gulu lathu la mainjiniya lingakuthandizeni kuyang'ana mfundo izi kuti musankhe yankho labwino kwambiri la ma valve, ndikuwonetsetsa kuti ndi odalirika komanso ogwira ntchito bwino kuyambira pakupanga mpaka kugwira ntchito.

Wokonzeka kunena motsimikiza? [Fufuzani zofunikira zathu zaukadaulo zama valve a mpira opindika komanso opindika] kapena [Lumikizanani ndi gulu lathu lothandizira mainjiniya] kuti mukambirane za munthu payekha.
