Onani Chithunzi Chachikulu
Pali ma valve ambiri ogulitsa mafakitale omwe amapezeka pamsika.Mitundu yosiyanasiyana ya valve ya mafakitale imagwira ntchito mosiyana.Ena amayendetsa kayendedwe ka zoulutsira mawu pomwe ena amapatula media.Ena amayendetsa njira zoulutsira nkhani.Izi zimasiyananso m'mapangidwe ndi kukula kwake.
Ma valve awiri omwe amagwiritsidwa ntchito kwambiri m'mafakitale ndi ma valve a mpira ndi ma valve a zipata.Zonsezi zimadziwika kuti zimapereka njira zotsekera zolimba.Nkhaniyi ifananiza ma valve awiriwa pazinthu zosiyanasiyana monga makina ogwirira ntchito, mapangidwe, madoko, ndi zina.
Kodi Vavu ya Mpira ndi chiyani?
Valavu ya mpira ndi gawo la banja la valve yotembenuka.Zimangotenga kutembenuka kwa madigiri 90 kuti atsegule kapena kutseka.Mapangidwe a valve a mpira ali ndi mpira wopanda dzenje womwe umakhala ngati diski yomwe imalola kuyenda kwa media.Nthawi zambiri pazinthu zopanda slurry, mavavu a mpira ndi oyenereranso ntchito zomwe zimafuna kutsekedwa mwamphamvu.
Kutsegula mwachangu ndi kutseka kwa mpira kumapangitsa kukhala kofunikira muzinthu zina zomwe zimafunikira kudzipatula kwa media.Ma valve a mpira nthawi zambiri amagwiritsidwa ntchito pamagetsi otsika.Mwachidule, mavavu a mpira ndi abwino kwambiri pakuwongolera ndi kuyang'anira media ndi kutsika kochepa.
Kodi Gate Valve ndi chiyani?
Kumbali inayi, ma valve a pachipata ndi a gulu la ma valve oyenda.Popanda kudziwika kuti valavu ya mpeni kapena slide valve, valve yachipata imakhala ndi diski yosalala kapena yamphepete yomwe imakhala ngati chipata.Chipata ichi kapena chimbale chimayang'anira kutuluka kwamadzimadzi mkati mwa valavu.Valve yachipata imagwiritsidwa ntchito bwino ngati njira yotsatsira ma media yomwe ili ndi kutsika kocheperako imakonda.
Ndi valavu yotseka yokhala ndi mphamvu yothamanga.Cholinga chake ndi chakuti zinthu ziziyenda bwino ngati kayendetsedwe ka kayendetsedwe kake.Zoyenera kwambiri pazofalitsa zokulirapo, chimbale chophwanyika cha mavavu a pachipata chimapangitsa kuti zikhale zosavuta kudula pamtundu woterewu.
Valve yachipata imakhalanso gawo la banja la rotary monga gudumu kapena actuator iyenera kuzunguliridwa kuti mphero kapena diski itseguke.Pamalo ake otseka, chipatacho chimayenda pansi ndi pakati pa mipando iwiri yomwe ili pamtunda wapamwamba wa diski komanso pansi pake monga momwe tawonetsera pa chithunzi pamwambapa.
Vavu ya Chipata vs. Vavu ya Mpira: Njira Yogwirira Ntchito
Kodi Vavu Ya Mpira Imagwira Ntchito Motani?
Ma valve a mpira ali ndi gawo lopanda kanthu lomwe limalola kuti media idutse.Ngati muyang'ana pamtanda wa valavu ya mpira pansipa, ntchitoyo imadutsa kuzungulira kwa shaft kapena tsinde ndi kotala la kutembenuka.Tsinde ndi perpendicular mbali ya mpira wa valve.
Madzi amaloledwa kudutsa pamene tsinde lili pa ngodya yoyenera ponena za diski ya mpira.Kusuntha kwapambali kwa media kumakhala ndi gawo lofunikira pakutseka kotseka.Ma valve a mpira amagwiritsa ntchito kuthamanga kwamadzimadzi kuti agwire pa valavu kapena mpando kuti apereke chisindikizo cholimba, kutengera kasinthidwe ka valve ya mpira.
Mavavu a mpira amatha kukhala doko lathunthu kapena doko lochepetsedwa.Valavu yodzaza ndi doko imatanthawuza kuti m'mimba mwake ndi yofanana ndi chitoliro.Izi zimathandizira kutsika kwa torque yogwira ntchito komanso kutsika kwamphamvu.Komabe, palinso mtundu wocheperako wa doko pomwe kukula kwa valavu kumakhala kocheperako kuposa kukula kwa chitoliro.
Kodi Valve Yachipata Imagwira Ntchito Motani?
Ma valve a zipata amagwira ntchito pokweza chipata kapena disc kuti alole media kudutsa mu valve.Ma valve amtunduwu amangolola kuyenda kwa unidirectional ndikutsika pang'ono.Nthawi zambiri mumawona ma valve a zipata okhala ndi mawilo amanja.Wwilo la m'manja limamangiriridwa kunyamula.
Pali mitundu iwiri ya mapangidwe a tsinde la valve pachipata.Pamene gudumu lamanja ili likuzungulira, tsinde limakwera kumalo akunja ndipo, panthawi imodzimodziyo, imakweza chipata.Mtundu wina wa valve pachipata ndi valavu yosakwera.Izi zimadziwika ndi tsinde lomwe limalowetsedwa mumphepo, potero liziwulula kwa atolankhani.
Pamene valve yachipata ikutsegula, njirayo imakhala yaikulu.Njira yoyendetsera siili yolunjika chifukwa chakuti media zitha kukhala zopanda kanthu monga momwe tawonera m'fanizo ili pansipa.Ngati valavu yachipata ikugwiritsidwa ntchito ngati throttle, ingakhale ndi kuthamanga kosagwirizana.Izi zipangitsa kugwedezeka.Kugwedezeka kotereku kumatha kuwononga disk.
Mayendedwe a Valve Flow
Ma valve a mpira ndi ma valve a zipata, mwamwambo, amakhala ndi mbali ziwiri.Izi zikutanthauza kuti ma valve a mpira ali ndi mphamvu zoletsa zofalitsa kuchokera kumapeto kwa mtsinje ndi kumapeto kwa mtsinje.Onani chithunzi pansipa.
Mphamvu ya Chisindikizo cha Vavu
Kwa mavavu a mpira, zisindikizo zimatha kukhazikitsidwa pamapangidwe a valve yoyandama ndipo zimatha kuyandama pama valve okwera mpira.Popeza ma valve a mpira nthawi zambiri amagwiritsidwa ntchito pazitsulo zochepa, poganizira momwe zimagwirira ntchito, zisindikizo zoyambirira nthawi zambiri zimapangidwa ndi PTFE ndi zipangizo zina.
Ngakhale kutseka mwamsanga ndi kutsegula valavu ya mpira kungakhale kopindulitsa, izi zingayambitsenso mavuto.Mavavu a mpira amatha nyundo yamadzi kapena kuthamanga kwadzidzidzi kwamphamvu pakutseka kwa valve.Izi zimawononga mipando ya valve ya mpira.
Kuphatikiza apo, nyundo yamadzi imatha kuwonjezera kupanikizika mkati mwa valavu ya mpira.M'malo omwe zinthu zoterezi zitha kuchitika, mwachitsanzo, zinthu zoyaka moto, pamakhala chisindikizo chapampando wadzidzidzi, chomwe nthawi zambiri chimapangidwa ndi chitsulo.Ichi ndi chotchinga chachiwiri mumikhalidwe yomwe chisindikizo cha elastomeric chimawonongeka muntchito zothamanga kwambiri.Kuti muchepetse kupanikizika, ma valve a mpira amatha kuyikapo mpweya wopondereza.
Ma valve a zipata amachepetsa kutsika kwamphamvu akatsegulidwa kwathunthu.Izi zimachitika pogwiritsa ntchito mawonekedwe amtundu uliwonse.Izi zikutanthauza kuti kukula kwa valve ndikofanana ndi kukula kwa chitoliro.Ndi chifukwa cha chikhalidwe ichi cha ma valve a pakhomo omwe amawapatsa mwayi kuposa ma valve a mpira.Kuthirira madzi sikuchitika mu ma valve a zipata.
Kutsika kwa valve yachipata ndikuti, kusiyanitsa kwakukulu kumachitika nthawi zambiri pakutseka.Kukangana kungayambitse mipando ndi disk kuvala.
Kusiyanasiyana kwa Mavavu ndi Zomangamanga
Kusiyanitsa kwakukulu pakati pa ma valve a mpira ndi ma valve a zipata ndi mawonekedwe awo ngakhale akugwira ntchito mofanana.
Kwa mavavu a mpira, kusuntha kwa media ndikosavuta.Kupatula izi, mapangidwe a valve a mpira amalola kuti azikhala nthawi yayitali ngakhale atagwiritsidwa ntchito kwambiri.Inde, munthu ayenera kuganiziranso za mtundu wa zinthu zomwe zimagwiritsidwa ntchito pozipanga.
Ngakhale ma valve a mpira samapereka kuwongolera bwino, kutsekeka kwawo kolimba ndi chimodzi mwazabwino kwambiri pamapulogalamu otsika.Mavavu a mpira ndi odalirika pankhaniyi.Kutsika kwapang'onopang'ono ndi mtundu wina wa mavavu a mpira.Komabe, chifukwa cha kutembenuka kwa kotala kwa mavavu a mpira, zimatengera malo ochulukirapo.
Vavu yachipata, kumbali ina, imagwiritsa ntchito gudumu lamanja kutsegula kapena kutseka diski.Thupi la valve ndilochepa kwambiri, motero, malo opapatiza okha amafunikira.Mosiyana ndi ma valve a mpira, ma valve a pachipata, amapereka chiwongolero chowongolera bwino chifukwa ali ndi mphamvu zogwedeza.Ikhoza kusakhala ndi kutsekedwa mwamsanga ndi mphamvu, koma imatha kulamulira osati kutuluka kwa media komanso kukakamiza kwake.
