Thevalavu ya butterfly ya pulasitikichikugwirizana ndi dongosolo mapaipi m'njira zotsatirazi:

Kulumikizana kowotcherera matako: Mbali yakunja ya gawo lolumikizira valavu ndi yofanana ndi mainchesi akunja a chitoliro, ndipo kumapeto kwa gawo lolumikizira valavu kumatsutsana ndi kumapeto kwa chitoliro chowotcherera;

Kulumikizana kwazitsulo zazitsulo: gawo logwirizanitsa la valve liri mu mawonekedwe a socket, omwe amamangiriridwa ku chitoliro;

Kulumikizana kwa socket ya electrofusion: gawo lolumikizira ma valve ndi mtundu wa socket wokhala ndi waya wotenthetsera wamagetsi womwe umayikidwa mkati mwake, ndipo ndi kulumikizana kwa electrofusion ndi chitoliro;

Socket hot-melt kugwirizana: gawo lolumikizira valavu lili mu mawonekedwe a socket, ndipo limalumikizidwa ndi chitoliro ndi socket yosungunuka;

Kulumikizana kwazitsulo zazitsulo: Gawo logwirizanitsa valavu liri mu mawonekedwe a socket, omwe amamangiriridwa ndi kutsekedwa ndi chitoliro;

Kulumikizana kwa mphete yosindikizira ya socket: Gawo lolumikizira valavu ndi mtundu wa socket wokhala ndi mphete yosindikizira mphira mkati, yomwe imakhazikika ndikulumikizidwa ndi chitoliro;

Kulumikizana kwa Flange: Gawo lolumikizira valavu lili mu mawonekedwe a flange, omwe amalumikizana ndi flange pa chitoliro;

Kulumikizana kwa ulusi: Gawo lolumikizira valavu lili mu mawonekedwe a ulusi, womwe umalumikizidwa ndi ulusi pa chitoliro kapena kuyika chitoliro;

Kulumikizana kwamoyo: Gawo lolumikizira ma valve ndi kulumikizana kwamoyo, komwe kumalumikizidwa ndimapaipi kapena zomangira.

Valavu imatha kukhala ndi njira zolumikizirana zosiyanasiyana nthawi imodzi.

mfundo ntchito:

Ubale pakati pa kutsegula kwa valavu ya gulugufe wa pulasitiki ndi kuthamanga kwa kayendedwe kameneka kumasintha motsatira.Ngati imagwiritsidwa ntchito kuwongolera kuyenda, mawonekedwe ake oyenda nawonso amagwirizana kwambiri ndi kukana kwa mipope.Mwachitsanzo, mapaipi awiri amaikidwa ndi m'mimba mwake ndi mawonekedwe a valve, koma kutayika kwa payipi kumakhala kosiyana, ndipo kuthamanga kwa valve kudzakhalanso kosiyana kwambiri.

Ngati valavu ili m'chigawo chokhala ndi phokoso lalikulu, kumbuyo kwa mbale ya valve kumakhala kosavuta ku cavitation, zomwe zingawononge valavu.Nthawi zambiri, imagwiritsidwa ntchito kunja kwa 15 °.

Pamene valavu ya gulugufe ya pulasitiki ili pakati pa kutseguka, mawonekedwe a kutsegula opangidwa ndi thupi la valavu ndi kumapeto kwa mbale ya butterfly zimakhazikika pazitsulo za valve, ndipo mbali ziwirizo zimapangidwira kuti zikwaniritse mayiko osiyanasiyana.Kutsogolo kwa mbale ya gulugufe kumbali imodzi kumayenda molunjika kumene madzi akudutsa, ndipo mbali inayo ndi yotsutsana ndi mmene madziwo amayendera.Choncho, mbali imodzi ya thupi la valve ndi mbale ya valve imapanga kutsegula ngati nozzle, ndipo mbali inayo ndi yofanana ndi kutsegula kwa throttle.Mbali yamphuno imakhala ndi liwiro lothamanga kwambiri kuposa mbali ya throttle, ndipo kupanikizika koipa kumapangidwa pansi pa valve ya throttle side.Zisindikizo za mphira nthawi zambiri zimagwa.

Mavavu agulugufe apulasitiki ndi ndodo za agulugufe alibe luso lodzitsekera.Poyika mbale ya agulugufe, chochepetsera giya ya nyongolotsi chiyenera kuikidwa pa ndodo ya valve.Kugwiritsa ntchito makina ochepetsera nyongolotsi sikungangopangitsa kuti mbale yagulugufe ikhale yodzitsekera yokha ndikuyimitsa mbale yagulugufe pamalo aliwonse, komanso kuwongolera magwiridwe antchito a valavu.

Ma torque ogwiritsira ntchito valavu ya gulugufe wa pulasitiki ali ndi makhalidwe osiyanasiyana chifukwa cha kutsegula ndi kutseka kosiyanasiyana kwa valve.Valavu yagulugufe yopingasa, makamaka valavu yayikulu-yam'mimba mwake, chifukwa cha kuya kwa madzi, torque yomwe imapangidwa ndi kusiyana pakati pa mitu yamadzi yam'mwamba ndi yotsika ya shaft ya valve sichinganyalanyazidwe.Kuonjezera apo, pamene chigongono chimayikidwa kumbali yolowera ya valve, kutuluka kwa tsankho kumapangidwa, ndipo torque idzawonjezeka.Valavu ikakhala pakati pakutsegulira, njira yogwirira ntchito iyenera kudzitsekera yokha chifukwa chakuchita kwa torque yamadzi.

Valavu ya gulugufe ya pulasitiki ili ndi dongosolo losavuta, lopangidwa ndi magawo ochepa chabe, ndipo limasunga zinthu zomwe zimagwiritsidwa ntchito;kukula kwakung'ono, kulemera kwapang'onopang'ono, kukula kwazing'ono, torque yaing'ono yoyendetsa galimoto, ntchito yosavuta komanso yofulumira, imangofunika kuzungulira 90 ° kuti mutsegule ndi kutseka mwamsanga;ndipo Panthawi imodzimodziyo, imakhala ndi ntchito yabwino yosinthira kuyenda komanso kutseka ndi kusindikiza zizindikiro.Pamalo ogwiritsira ntchito mphamvu zazikulu ndi zapakati, zapakati ndi zotsika, valavu ya butterfly ndiyo mawonekedwe a vavu akuluakulu.Pamene valavu gulugufe ali bwinobwino lotseguka malo, makulidwe a gulugufe mbale ndi kukana kokha pamene sing'anga umayenda mu valavu thupi, kotero kuthamanga dontho kwaiye valavu ndi yaing'ono, choncho ali bwino otaya kulamulira makhalidwe.Vavu ya gulugufe ili ndi mitundu iwiri yosindikiza: zotanuka chisindikizo ndi chitsulo chisindikizo.Vavu yosindikizira yowala, mphete yosindikizira imatha kuikidwa pathupi la valve kapena kumangirizidwa m'mphepete mwa mbale yagulugufe.Mavavu okhala ndi zisindikizo zachitsulo nthawi zambiri amakhala ndi moyo wautali kuposa mavavu okhala ndi zisindikizo zotanuka, koma ndizovuta kupeza chisindikizo chonse.Chisindikizo chachitsulo chimatha kutengera kutentha kwapamwamba kogwira ntchito, pomwe chosindikizira chotanuka chimakhala ndi vuto lochepa chifukwa cha kutentha.Ngati valavu ya butterfly ikufunika kuti igwiritsidwe ntchito ngati kayendetsedwe ka kayendetsedwe kake, chinthu chachikulu ndikusankha molondola kukula ndi mtundu wa valve.Kapangidwe ka valavu ya gulugufe ndi yabwino kwambiri popanga ma valve akulu akulu.Ma valve a butterfly samangogwiritsidwa ntchito kwambiri m'mafakitale ambiri monga mafuta, gasi, mankhwala, ndi mankhwala amadzi, komanso amagwiritsidwa ntchito poziziritsa madzi m'malo opangira magetsi otentha.Mavavu agulugufe omwe amagwiritsidwa ntchito kwambiri amaphatikiza ma valve agulugufe amtundu wa wafer ndi ma valve agulugufe amtundu wa flange.Mavavu agulugufe amalumikizidwa pakati pa mapaipi awiri okhala ndi mabawuti olimba.Ma valve a butterfly ali ndi ma flanges pa valve.Ma flanges pa malekezero onse a valavu amalumikizidwa ndi ma flanges a chitoliro ndi mabawuti.Kugwira ntchito kwamphamvu kwa valve kumatanthawuza kukhoza kwa valve kupirira kupanikizika kwapakati.Valavu ndi mankhwala opangidwa ndi makina omwe amanyamula kupanikizika kwa mkati, choncho ayenera kukhala ndi mphamvu zokwanira komanso zolimba kuti zitsimikizire kuti zikugwiritsidwa ntchito kwa nthawi yaitali popanda kusweka kapena kusokoneza.

Pogwiritsa ntchito mphira wa anti-corrosion synthetic ndi polytetrafluoroethylene, mavavu agulugufe amatha kuwongolera ndikukwaniritsa ntchito zosiyanasiyana.M'zaka khumi zapitazi, mavavu agulugufe osindikizira zitsulo apangidwa mofulumira.Ndi kugwiritsa ntchito kukana kutentha kwambiri, kukana kutentha kwapansi, kukana kwa dzimbiri mwamphamvu, kukana kukokoloka kwamphamvu, ndi zida zamphamvu za aloyi mu mavavu agulugufe, mavavu agulugufe osindikiza zitsulo akhala akugwiritsidwa ntchito pakutentha kwambiri, kutentha pang'ono, komanso kukokoloka kwamphamvu.Lakhala likugwiritsidwa ntchito kwambiri pansi pazikhalidwe zina zogwirira ntchito ndipo m'malo mwa valve yapadziko lonse lapansi,valavu pachipatandi valavu ya mpira.
