Pali mitundu yambiri yavalavu butterfly, kuphatikizapo kudula mwamsanga ndi kusintha kosalekeza.Amagwiritsidwa ntchito kwambiri pamapaipi amadzimadzi ndi gasi otsika kwambiri.Ndikoyenera pa nthawi zomwe kutayika kwa mphamvu zochepetsera sikuli kwakukulu, kusintha kwa kayendedwe ka kayendedwe kake kumafunika, ndipo zofunikira zotsegula ndi kutseka ndizofulumira;nthawi zambiri kutentha kumakhala pansi pa 300 ℃ ndipo kupanikizika kumakhala pansi pa 40 kg (ma valve agulugufe nthawi zambiri amagwiritsa ntchito kupanikizika kochepa, monga zapakhomo. Ochepa kwambiri amatha kukwaniritsa CL600), sing'anga imagwiritsidwa ntchito pamadzi ndi gasi, ndipo sing'anga si yovuta, ndi granular medium ingagwiritsidwenso ntchito.
Monga valavu yagulugufe yosindikizidwa, idabweretsa chitukuko chofulumira pambuyo pa kutuluka kwa mphira wopangira, kotero ndi mtundu watsopano wa valve yotseka.M'dziko langa mpaka zaka za m'ma 1980, mavavu agulugufe ankagwiritsidwa ntchito makamaka popanga ma valve otsika, ndipo mpando wa valve unali wopangidwa ndi mphira wopangira.Pofika m'zaka za m'ma 1990, chifukwa cha kuwonjezeka kwa kusinthana ndi mayiko akunja, ma valve agulugufe osindikizira (zitsulo-zitsulo) adapangidwa mofulumira.Pakalipano, pali mafakitale ambiri a valve omwe amatha kupanga ma valve agulugufe otsekedwa ndi zitsulo zolimba, zomwe zimapangitsa kuti malo ogwiritsira ntchito agulugufe achuluke.
Zofalitsa zomwe valavu ya butterfly imatha kunyamula ndi kulamulira imaphatikizapo madzi, madzi osungunuka, madzi ozungulira, madzi osambira, madzi a m'nyanja, mpweya, mpweya, mpweya wamadzimadzi, ufa wouma, matope, slurry zipatso ndi zosakaniza ndi zolimba zoyimitsidwa.
Ma valve a butterfly ndi oyenera kuwongolera kayendedwe kake.Popeza kuthamanga kwa vavu ya gulugufe mu payipi kumakhala kwakukulu, kuwirikiza katatu kuposa kwa valve.Choncho, posankha valavu ya gulugufe, chikoka cha kutayika kwa dongosolo la payipi chiyenera kuganiziridwa bwino.Kutaya kwamphamvu kwa mbale ya gulugufe kuyenera kuganiziridwanso pamene mbale ya butterfly yatsekedwa.Kulimba.Komanso, m'pofunika kuganizira kuchepetsa kutentha kwa ntchito kuti zotanuka valavu mpando chuma akhoza kupirira pa kutentha kwambiri.Kutalika kwa mapangidwe ndi kutalika kwa valavu ya butterfly ndi yaying'ono, kutsegulira ndi kutseka kumathamanga, ndipo kumakhala ndi makhalidwe abwino olamulira madzimadzi.Mfundo yokhazikika ya valavu ya gulugufe ndi yabwino kwambiri popanga mavavu akuluakulu.Pamene valavu ya butterfly ikufunika kuti iwononge kutuluka, chinthu chofunika kwambiri ndikusankha molondola kukula ndi mtundu wa valavu ya butterfly kuti igwire bwino ntchito.
1. Nthawi zambiri, pakuwongolera, kuwongolera ndi matope, kapangidwe kake kamayenera kukhala kakang'ono m'litali komanso mwachangu pakutsegula ndi kutseka liwiro (1/4 revolution).Kutsika kwapakati (kusiyana kwapang'onopang'ono), valavu ya butterfly ndiyofunikira.
2. Valve ya butterfly ingagwiritsidwe ntchito pamene kusintha kwa malo awiri, njira yochepetsera, phokoso laling'ono, cavitation ndi gasification phenomenon, pang'ono kutayikira mumlengalenga, ndi abrasive media zilipo.
3. Pamene valavu ya butterfly ikugwiritsidwa ntchito pazikhalidwe zapadera monga kusintha kwa throttling, kapena zofunikira zosindikizira mwamphamvu, kapena kuphulika kwakukulu, kutentha kochepa (cryogenic) ndi zina zogwirira ntchito, m'pofunika kugwiritsa ntchito chisindikizo chachitsulo chopangidwa mwapadera ndi katatu eccentric kapena valavu yagulugufe wodzipereka pa nthaka.
4. The centerline butterfly valve ndi yoyenera madzi abwino, zimbudzi, madzi a m'nyanja, madzi amchere, nthunzi, gasi lachilengedwe, chakudya, mankhwala, ndi mafuta zomwe zimafuna kusindikiza kwathunthu, kutayikira kwa zero kuyesa gasi, moyo wapamwamba, ndi kutentha kwa ntchito - - 10 ℃ ~ 150 ℃.Ndipo mitundu yosiyanasiyana ya asidi ndi alkali ndi mapaipi ena.
5. Valavu ya butterfly yotsekedwa yofewa ndi yoyenera kutsegulira ndi kutseka kwa njira ziwiri ndi kusintha kwa mpweya wabwino ndi kuchotsa fumbi mapaipi, ndipo amagwiritsidwa ntchito kwambiri mu mapaipi a gasi ndi madzi muzitsulo, mafakitale opepuka, mphamvu zamagetsi, ndi petrochemical systems.
6. Chitsulo chachitsulo chachitsulo chosindikizira ma valve awiri a butterfly eccentric ndi oyenera kutentha kwa m'tawuni, gasi, madzi ndi mapaipi ena a gasi, mafuta, asidi ndi alkali, monga chipangizo chowongolera ndi chogwedeza.
7. Kuphatikiza pa kugwiritsidwa ntchito ngati valavu yayikulu yolumikizirana ndi gasi (PSA), valavu yachitsulo ya Jinyong yosindikizidwa katatu eccentric butterfly valve ingagwiritsidwenso ntchito kwambiri mumafuta, petrochemical, mankhwala, zitsulo, magetsi ndi magetsi. minda ina.Ndi valve yachipata ndi valavu yapadziko lonse lapansi.Chinthu china chabwino.
