Vavu yagulugufe yolimbana ndi dzimbiri yokhala ndi fluoroplasticndi kuika polytetrafluoroethylene utomoni (kapena mbiri kukonzedwa) pa khoma lamkati la zitsulo kapena chitsulo gulugufe valavu kukakamiza mbali mbali kapena kunja kwa gulugufe mbali zamkati mwa akamaumba (kapena inlay) njira. Zapadera za ma valve agulugufe motsutsana ndi zida zowononga zamphamvu zimapangidwa kukhala mitundu yosiyanasiyana ya ma valve agulugufe ndi zotengera zokakamiza.
Mu zida zotsutsana ndi dzimbiri, PTFE ili ndi magwiridwe antchito osayerekezeka. Kuwonjezera chitsulo chosungunuka, zoyambira fluorine ndi onunkhira hydrocarbons, angagwiritsidwe ntchito ndende zosiyanasiyana hydrochloric acid, asidi sulfuric, asidi nitric, aqua regia, asidi organic, wamphamvu oxidant, anaikira, alternating kuchepetsa asidi, alternating alkali ndi zosiyanasiyana organic wothandizila. ndi zochita mwachisawawa. Lining PTFE pa khoma lamkati la gulugufe valavu osati kugonjetsa zofooka za otsika mphamvu PTFE zakuthupi, komanso kuthetsa vuto la dzimbiri kukana zipangizo gulugufe valavu mutu. Kuchita bwino komanso kukwera mtengo. Kuphatikiza apo, kuwonjezera pa kukhazikika kwake kwamankhwala, PTFE ili ndi antifouling ndi zotsutsana ndi ndodo, ma coefficients ang'onoang'ono osunthika komanso osasunthika, komanso magwiridwe antchito abwino odana ndi mikangano ndi mafuta. Amagwiritsidwa ntchito ngati awiri osindikiza potsegula ndi kutseka ma valve a butterfly, ndipo m'pofunika kuchepetsa kusindikiza pamwamba. Mkangano pakati pa mavavu agulugufe ukhoza kuchepetsedwa, torque yogwiritsira ntchito ya gulugufe imatha kuchepetsedwa, ndipo moyo wautumiki wa mankhwalawo ukhoza kusintha.
Vavu ya butterfly yokhala ndi fluorine, yomwe imadziwikanso kuti anti-corrosion butterfly valve, imagwiritsidwa ntchito nthawi zambiri pogwira ntchito movutikira, kaya ndi mankhwala oopsa komanso owopsa, kapena kuwononga kwambiri mitundu yosiyanasiyana ya acid-base kapena organic solvents. Kugwiritsa ntchito molakwika kumabweretsa kuwonongeka kwakukulu kwachuma komanso koopsa chifukwa cha. Kugwiritsa ntchito bwino ndi kukonza valavu ya gulugufe kumatha kutalikitsa moyo wautumiki wa gulugufe wokhala ndi fluorine, ndiye ndi tsatanetsatane wanji womwe ungachitike kuti uteteze bwino?
1. Musanagwiritse ntchito, werengani mosamala buku la malangizo a gulugufe wopangidwa ndi fluorine.
2. Igwiritseni ntchito mkati mwa kupanikizika, kutentha ndi sing'anga zomwe zatchulidwa pa dzina kapena m'buku.
3. Mukagwiritsidwa ntchito, tetezani valavu ya gulugufe wokhala ndi mizere ya fluorine kuti isapangitse kupsyinjika kwakukulu kwa mapaipi chifukwa cha kusintha kwa kutentha, kuchepetsa kutentha, ndipo onjezerani mfundo zowonjezera zooneka ngati U musanayambe kapena pambuyo pa gulugufe.
4. Ndizoletsedwa kugwiritsa ntchito lever kuti mutsegule ndi kutseka valavu ya butterfly yokhala ndi fluorine. Samalani kuyang'ana malo otsegulira ndi kutseka ndi kuchepetsa chipangizo cha gulugufe wokhala ndi fluorine. Pambuyo potsegula ndi kutseka zili m'malo, musakakamize valavu kutseka, kuti musawononge msanga pamadzi osindikizira apulasitiki a fluorine.
5. Kwa ma media ena omwe sakhazikika komanso osavuta kuwola (mwachitsanzo, kuwonongeka kwa ma media ena kumayambitsa kufalikira kwa voliyumu ndikuwonjezera kupanikizika kwachilendo m'malo ogwirira ntchito), zomwe zingayambitse kuwonongeka kwa valve ya butterfly kapena kutayikira, njira ziyenera kuchitidwa kuti zithetsedwe. kapena kuchepetsa zinthu zomwe zimayambitsa kuwonongeka kwa zofalitsa zosakhazikika. . Posankha valavu ya butterfly, valavu ya butterfly yokhala ndi fluorine yokhala ndi chipangizo chothandizira kupanikizika chiyenera kusankhidwa poganizira za kusintha komwe kungachitike chifukwa cha kuwonongeka kosakhazikika komanso kosavuta kwa sing'anga.
6. Pakutivalavu ya butterfly yokhala ndi fluorinepapaipi yokhala ndi sing'anga yapoizoni, yoyaka, yophulika komanso yamphamvu zowononga, ndikoletsedwa m'malo mwake kulongedza mopanikizika. Ngakhale kuti valavu ya butterfly yokhala ndi fluorine imakhala ndi ntchito yosindikiza pamwamba pakupanga, sikulimbikitsidwa kuti mutenge m'malo mwa kupanikizana.
7. Pamapaipi okhala ndi sing'anga yoyaka yokha, njira ziyenera kuchitidwa kuonetsetsa kuti kutentha kwapakati ndi momwe zimagwirira ntchito sizingadutse malo oyatsira apakati kuti apewe ngozi yobwera chifukwa cha kuwala kwa dzuwa kapena moto wakunja.
Sing'anga yogwiritsidwa ntchito: mchere wambiri wa acid-base ndi zosungunulira organic.
