Onani Chithunzi Chachikulu
Ma valve a mafakitale amabwera m'mapangidwe osiyanasiyana ndi njira zogwirira ntchito.Zina ndi zodzipatula pomwe zina zimangogwira mtima.
Mu dongosolo la mapaipi, pali ma valve omwe amagwiritsidwa ntchito kuwongolera kuthamanga, kuthamanga kwa kuthamanga ndi zina.Ma valve olamulira oterowo amagwiritsidwa ntchito poyang'anira ndi kuyang'anira kusinthasintha kwa kayendetsedwe kake kotero kuti zotsirizirazo zimamatirira pafupi kwambiri ndi zomwe mukufuna.Komabe, valavu yowongolera ndi imodzi mwama valve omwe amatengedwa kuti ndi osavomerezeka papaipi popeza valavuyi ili ndi zomwe mainjiniya ena amawona kuti ndizovuta kwambiri.
Pali mitundu yambiri ya ma valve owongolera.Mmodzi wa iwo ndi flanged chipata control valve.Nkhaniyi ikufotokoza momwe valavu yowongolera chipata cha flanged imagwirira ntchito, ntchito zake ndi zina.
Kodi Control Valve ndi chiyani?
Mwa kutanthauzira, valavu yolamulira ndi valve iliyonse yomwe imatha kuyendetsa kayendedwe kazofalitsa, kupanikizika kwake pokhudzana ndi chipangizo chowongolera kunja.Kawirikawiri, ma valve olamulira amagwirizanitsidwa ndi kayendetsedwe ka kayendetsedwe kazofalitsa koma izi zimatha kusinthanso machitidwe ena.
Valve yowongolera imawonedwa ngati gawo lofunika kwambiri la loop control.Zosintha zomwe zimachitika ndi valavu yowongolera zimakhudza mwachindunji njira yomwe valavu yotere imalumikizidwa nayo.
Ma valve angapo a mafakitale amagwira ntchito ngati ma valve olamulira monga momwe tawonera mu tebulo ili m'munsimu.Ma valve a butterfly ndi globe angagwiritsidwe ntchito pogwedeza.Ngakhale ma valve a mpira ndi ma plug ma valve ali ndi mphamvu zogwedeza, izi nthawi zambiri sizikhala zoyenerera ntchito yotere chifukwa cha mapangidwe a mitundu iwiri ya valve.Amakonda kuwonongeka kwa mikangano.
Ma valve owongolera amakhala ndi magulu osiyanasiyana ochiritsira.Itha kukhala ndi zoyenda zozungulira monga zapadziko lonse lapansi, ma valve otsina ndi ma diaphragm.Itha kukhalanso ndi kayendedwe kozungulira ngati mpira, gulugufe ndi mavavu a pulagi.
Kumbali ina, ma valve otetezera chitetezo ali ndi mphamvu zochepetsera kupanikizika.Komanso, valavu yapadziko lonse lapansi, valavu ya mpira, ndi valavu yamapulagi amatha kusintha komwe kumayendera ma media.Komabe, pali zosiyana.Ma valve a globe aang'ono okha, mpira wa multiport ndi ma plug valve angasinthe njira ya media.

Control Valve Features
Mavavu owongolera omwe ali m'gulu loyenda mozungulira amatha kutsitsa mafunde ang'onoang'ono.Mogwirizana ndi ntchito zothamanga kwambiri, njira yothamanga ya mtundu uwu wa valve imagwedezeka.Kuti asindikize bwino, boneti ndi yosiyana.Zolumikizira nthawi zambiri zimakhala ndi flanged kapena ulusi.
Control Valve Features
Mavavu a globe okhala ndi mipando imodzi amafunikira mphamvu yayikulu kuti asunthire tsinde koma amapereka kutseka kolimba.Mosiyana ndi zimenezi, ma valve a globe okhala ndi awiri amafunikira mphamvu yaying'ono kuti asunthire tsinde koma sangathe kukwaniritsa kutsekedwa kolimba kwa valavu imodzi yokha ya globe.Kuphatikiza apo, zigawo zake zimatha mosavuta.
Koma ma valve a diaphragm amagwiritsa ntchito mpando wonga chishalo kuti atseke valavu.Mtundu uwu umapezeka kawirikawiri m'mapaipi omwe amakhudzana ndi zowononga zowonongeka.
Valavu yoyendetsera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kabwino kakeIkhozanso kuchira bwino kuchokera ku madontho apansi.Zili ndi mphamvu zambiri zofalitsa ndi zochepa zovala zonyamula.Ma valve a butterfly amapereka kutseka kolimba komanso kutsika kwamphamvu.
Control Valve Working Mechanism
Monga tanena kale, ma valve owongolera nthawi zambiri amagwiritsidwa ntchito kuwongolera kayendedwe ka media.Chimodzi mwa zifukwa zomwe izi ziyenera kuchitikira ndi kusintha kwa katundu wokakamiza.Nthawi zambiri, pali sensor yomwe imawopseza dongosolo la kusintha kwamitundu yosiyanasiyana.Pambuyo pake, wolamulirayo amatumiza chizindikiro ku valavu yolamulira, yomwe imakhala ngati minofu, motero, imayendetsa kayendetsedwe kake monga momwe tawonera pa chithunzi pansipa:
Flanges ndi chiyani?
Flanges ndi mfundo zomwe zimagwirizanitsa ma valve, mapampu ndi zina zotero ku dongosolo la chitoliro.Kusindikiza kumachitika kudzera m'maboliti kapena ma welds okhala ndi gasket pakati.Kudalirika kwa ma flanges kumadalira njira yopangira mgwirizano wokhudzana ndi machitidwe osinthika.
Kupatula kuwotcherera flanges ndi ambiri kujowina njira mu dongosolo chitoliro.Ubwino wa ma flanges ndikuti amalola kuti valavu iwonongeke, ngakhale popanda kuchotsa zigawo zazikulu za valve.
Nthawi zambiri, ma flanges amakhala ndi zinthu zofanana ndi thupi la valve kapena chitoliro.Zomwe zimagwiritsidwa ntchito kwambiri pa flanges ndi zitsulo za carbon steel.Zida zina zomwe zimagwiritsidwa ntchito ndizomwe zili pansipa"

Kodi Flanged Gate Control Valve ndi chiyani?
Valve yachipata cha flanged ndi mtundu wa valve yachipata yokhala ndi malekezero opindika.Uwu ndi mtundu wa valve womwe uli ndi ntchito zambiri.Izi zitha kukhala ngati valavu yodzipatula komanso valavu yopumira.
Pokhala valavu yachipata, ndi yachuma chifukwa cha mapangidwe ake.Kuphatikiza apo, valavu yoyang'anira zipata za flanged imatha kutseguka kapena kutseka mwamphamvu ndipo sichingataye madontho amphamvu kwambiri kotero kuti kuthamanga kwake kungokhala ndi kusintha kochepa.
Kulumikiza actuator ndi chojambulira chotsitsa chakutali, valavu yachipata imakhala valavu yowongolera.Ndi disc yake, imatha kugwedezeka kumlingo wina.
Kuti valavu imangiridwe ku payipi, ma flanges amafunika kutsekedwa ndi kuwotcherera kuti atetezedwe.Valavu yachipata cha flanged imatsatira miyezo ya ASME B16.5.Nthawi zambiri, kapangidwe kameneka kamagwiritsa ntchito diski yamtundu wa wedge ngati chinthu chotseka.
Valavu yamtunduwu imagwiritsidwa ntchito pamagetsi otsika komanso kutentha.Pokhala ndi makhalidwe a valve pachipata, ubwino wa valavu yachipata cha flanged ndikuti ilibe madontho otsika kwambiri.
Mapulogalamu a Flanged Gate Control Valve
Ma valve owongolera zipata za flanged amagwiritsidwa ntchito pazotsatira zotsatirazi.
