Chipata cha valvendivalavu ya butterflyndi ma valve awiri omwe amagwiritsidwa ntchito kwambiri. Onsewa ndi osiyana kwambiri malinga ndi kapangidwe kawo ndi kugwiritsa ntchito njira, kusinthasintha ndi zochitika zogwirira ntchito, etc. Nkhaniyi ithandiza ogwiritsa ntchito kumvetsetsa kusiyana pakati pama valve pachipatandivalavu butterflymozama kwambiri, kuti athandize bwino ogwiritsa ntchito kusankha mavavu.
Asanafotokoze kusiyana pakativalve pachipatandi valavu gulugufe, tiyeni tione matanthauzo awiri. Mwinamwake kuchokera ku tanthawuzo, mukhoza kupeza mosamala kusiyana kwake.
Ma valve a zipata, monga momwe dzinalo likusonyezera, akhoza kudula sing'anga mu payipi ngati chipata, chomwe ndi mtundu wa valve yomwe tidzagwiritse ntchito popanga ndi moyo. Kutsegula ndi kutseka gawo lavalve pachipataimatchedwa mbale ya pachipata. The chipata mbale ntchito kunyamula zoyenda, ndi mayendedwe ake ndi perpendicular otaya malangizo sing'anga mu payipi madzimadzi. Thevalve pachipatandi mtundu wa valve truncation, yomwe imatha kutsegulidwa kapena kutsekedwa kwathunthu, ndipo kuthamanga kwa magazi sikungasinthidwe.
Valve ya butterfly, yomwe imadziwika kuti flip valve.Kutsegula ndi kutseka kwake ndi mbale ya butterfly yofanana ndi disc, yomwe imakhazikika pa tsinde ndikuzungulira tsinde la tsinde kuti litsegule ndi kutseka. Njira yoyendetseravalavu ya butterflyimazunguliridwa pomwe ili ndipo imangotenga 90 ° kuzungulira kuchokera kutseguka kwathunthu mpaka kutseka kwathunthu. Komanso, gulugufe mbale valavu gulugufe palokha alibe kudziletsa kutseka. Chotsitsa cha turbine chiyenera kukhazikitsidwa pa tsinde. Ndi izo, valavu gulugufe ali ndi mphamvu kudziletsa, ndipo pa nthawi yomweyo, akhoza kusintha ntchito valavu gulugufe.
Pambuyo pomvetsetsa tanthauzo lavalve pachipatandi valavu butterfly, kusiyana pakativalve pachipatandi valavu butterfly ikufotokozedwa pansipa:
1. Kusiyana kwa mphamvu zamagalimoto
Pakutanthauzira pamwamba, timamvetsetsa kusiyana pakati pa mayendedwe ndi njira yoyendetseravalve pachipatandi valavu butterfly. Kuonjezera apo, chifukwa chitseko cha chipata chikhoza kutsegulidwa kwathunthu ndi kutsekedwa, kuthamanga kwa kuthamanga kwa valve ya chipata kumakhala kochepa pamene kutsegulidwa kwathunthu; pamene avalavu ya butterflykwathunthu lotseguka, ndi makulidwe avalavu ya butterflyali ndi kukana kwa circulation medium. Komanso, kutsegula kutalika kwavalve pachipatandi okwera, kotero kutsegula ndi kutseka liwiro ndi pang'onopang'ono; pamene avalavu ya butterflyzimangofunika kuzungulira 90 ° kuti mukwaniritse kutsegula ndi kutseka, kotero kutsegula ndi kutseka kuli mofulumira.
2. Kusiyana kwa maudindo ndi ntchito
Kusindikiza kwa valve ya pachipata ndikwabwino, kotero kumagwiritsidwa ntchito kwambiri m'mapaipi omwe amafunikira kusindikiza mwamphamvu ndipo safunikira kusinthidwa mobwerezabwereza kuti adule ma media. Valve yachipata sichingagwiritsidwe ntchito kuwongolera kuyenda. Kuonjezera apo, chifukwa kutsegula ndi kutseka kwa valve ya chipata kumachedwa, sikuli koyenera kwa mapaipi omwe amafunika kudulidwa mwamsanga. Vavu yagulugufe imagwiritsidwa ntchito kwambiri. Valve ya butterfly sichikhoza kuchepetsedwa, komanso imakhala ndi ntchito yokonza kayendedwe kake. Kuonjezera apo, valavu ya butterfly imatsegula ndi kutseka mwamsanga, ndipo imathanso kutsegula ndi kutseka kawirikawiri, makamaka yoyenera kugwiritsidwa ntchito pazochitika zomwe kutsegula kapena kudula mofulumira kumafunika.
Maonekedwe ndi kulemera kwa valavu ya butterfly ndi yaying'ono kusiyana ndi ya valve ya pakhomo, kotero m'madera ena omwe ali ndi malo ochepa oyikapo, tikulimbikitsidwa kugwiritsa ntchito valavu ya butterfly yopulumutsa malo. Mavavu agulugufe ndi omwe amagwiritsidwa ntchito kwambiri m'mavavu akulu akulu, ndipo mavavu agulugufe amalimbikitsidwanso pamapaipi apakatikati okhala ndi zonyansa ndi tinthu tating'onoting'ono.
Posankha ma valve muzochitika zambiri zogwirira ntchito, ma valve a butterfly asintha pang'onopang'ono mitundu ina ya ma valve ndikukhala chisankho choyamba kwa ogwiritsa ntchito ambiri.
3. Kusiyana kwa mtengo
Pansi pa kukakamizidwa komweko ndi calibre, mtengo wa valve ya chipata ndi wapamwamba kuposa wa valavu ya butterfly. Komabe, valavu ya gulugufe ikhoza kukhala yayikulu kwambiri, komanso mtengo wamtundu waukuluvalavu ya butterflysichitsika mtengo kuposa valve yachipata.
