Ndi njira zingati zodzitetezera zomwe mukudziwa poika mavavu? Mfundo zofunikira pakugwiritsa ntchito valavu ya anticorrosive ya fluorine yokhala ndi pulasitiki Pamene valavu imayikidwa, pofuna kuteteza zitsulo, mchenga ndi matupi ena akunja kuti asalowe mu valavu ndikuwononga malo osindikizira, m'pofunika kukhazikitsa fyuluta ndi valavu yothamanga; Pofuna kusunga kuyeretsedwa kwa mpweya woponderezedwa, kutsogolo kwa valavu muyenera kukhazikitsa cholekanitsa madzi, kapena fyuluta ya mpweya; Kuti muwone momwe ntchito ya valve ikuyendera panthawi yogwira ntchito, m'pofunika kukhazikitsa chida ndikuyang'ana valve; Kuti musunge kutentha kwa ntchito, yikani kusungunula kunja kwa valve; Kuyika pambuyo pa valve, valve yothandizira kapena check valve ...... ikufunika Pamene valve imayikidwa, pofuna kuteteza zitsulo, mchenga ndi matupi ena akunja kuti asalowetse valavu ndikuwononga malo osindikizira, ndikofunikira. kukhazikitsa valavu ndi fyuluta; Pofuna kusunga kuyeretsedwa kwa mpweya woponderezedwa, kutsogolo kwa valavu muyenera kukhazikitsa cholekanitsa madzi, kapena fyuluta ya mpweya; Kuti muwone momwe ntchito ya valve ikuyendera panthawi yogwira ntchito, m'pofunika kukhazikitsa chida ndikuyang'ana valve; Kuti musunge kutentha kwa ntchito, yikani kusungunula kunja kwa valve; Pakuyika pambuyo pa valve, muyenera kukhazikitsa valavu yotetezera kapena valavu; Poganizira ntchito yosalekeza ya valavu, yabwino pangozi, ikani dongosolo lofanana kapena njira yodutsa. 1. Malo otetezera ma valve owonetsetsa: Pofuna kupewa kutuluka kwa ma valve cheke kapena kubwereranso kwa media pambuyo pa kulephera, zomwe zimapangitsa kuwonongeka kwa khalidwe la mankhwala ndi ngozi, ma valve amodzi kapena awiri odulidwa amaikidwa patsogolo ndi pambuyo pake. Ngati ma valve awiri otseka aperekedwa, valavu yowunikira ikhoza kuchotsedwa mosavuta kuti igwiritsidwe ntchito. 2 chitetezo ma valve chitetezo: isanayambe kapena itatha njira yokhazikitsira nthawi zambiri sichimayikidwa valavu, pokhapokha ngati ingagwiritsidwe ntchito. Ngati mphamvu yapakati ili ndi tinthu tating'onoting'ono tomwe timakhudza valavu yachitetezo sichingatsekeke pambuyo pochoka, kukhazikitsa valavu yachipata yosindikizidwa kutsogolo ndi pambuyo pa chitetezo, valve yachipata iyenera kukhala yotseguka, valve yachipata. ndi valavu yachitetezo yokhala ndi valavu yoyendera ya DN20 kupita kumlengalenga. Pamene mpumulo wa sera ndi TV zina kutentha firiji kwa boma olimba, kapena kuchepetsa kuthamanga gasification ndi kuwala madzi sing'anga kutentha pansi madigiri 0 Celsius, valavu chitetezo amafuna nthunzi kutentha. Vavu yachitetezo pazambiri zowononga, kutengera kukana kwa dzimbiri kwa valavu, ganizirani kuwonjezera filimu yosaphulika yosaphulika polowera valavu. Valavu yotetezera gasi nthawi zambiri imaperekedwa ndi valavu yodutsa molingana ndi kukula kwake, ngati cholowera pamanja. 3. Zida zodzitchinjiriza zochepetsera ma valve: nthawi zambiri pamakhala mitundu itatu yoyika ma valve ochepetsa mphamvu. Miyezo yamagetsi imayikidwa isanayambe komanso itatha valavu yochepetsera kuti iwonetsetse kupanikizika musanayambe komanso pambuyo pake. Pali valavu yotetezedwa yotsekedwa bwino pambuyo pa valavu kuti ateteze kulephera kwa valve yochepetsera kuthamanga, valavu pambuyo pa kupanikizika kumapitirira kuthamanga kwabwino pamene kulumpha, kuphatikizapo valavu pambuyo pa dongosolo. Chitoliro chokhetsa chimayikidwa kutsogolo kwa valavu kuti chidule valavu, ntchito yaikulu ndiyo kukhetsa mtsinje wothamanga, ena amagwiritsa ntchito msampha. Ntchito yaikulu ya chitoliro chodutsa ndi pamene kuthamanga kwa valve kuchepetsa kulephera, kutseka valavu yochepetsera mphamvu isanayambe komanso itatha valavu yodulidwa, tsegulani valavu yodutsa, sinthani pamanja kayendetsedwe kake, yesetsani kuyendayenda kwakanthawi, kuti mukonze valavu yochepetsera kuthamanga kapena kusintha valavu yochepetsera kuthamanga. 4. Malo otetezera msampha: pali mitundu iwiri ya chitoliro cholambalala ndi chitoliro chodutsa pamphepete mwa msampha, kuchira kwa condensate ndi condensate osati kubwezera malipiro, kutulutsa ndi zofunikira zina zapadera za msampha, zikhoza kukhazikitsidwa mofanana. Msampha wokhala ndi valavu yodutsa umagwiritsidwa ntchito makamaka kutulutsa madzi ochulukirapo pamene payipi iyamba kuyenda. Mukamatsuka Msampha, SIKOyenera KUKHALA CONDENSATE KUPYOLERA PAPASI WABYPASS, zomwe zingapangitse nthunzi kuthawira mu RETURN WATER SYSTEM. Muzochitika zabwino, musayike chitoliro cholambalala. Pokhapokha ngati kutentha kwa kutentha kumafunika kwambiri, zida zotenthetsera zopangira mosalekeza ziyenera kukhala ndi chitoliro chodutsa. Mfundo tcheru ntchito fluorine alimbane pulasitiki anticorrosive vavu Fluorine alimbane pulasitiki odana dzimbiri valavu mu mafuta, makampani mankhwala, mankhwala, zitsulo, mphamvu yamagetsi ndi mafakitale ena kukhudzana asidi ndi zamchere ndi zina amphamvu zikuwononga TV chipangizo wakhala ntchito yabwino, koma momwe mungasankhire bwino, kugwiritsa ntchito bwino kwa valavu ya pulasitiki yokhala ndi fluorine, malinga ndi ogwiritsa ntchito athu pazaka zambiri zomwe zakhala zikuchitikira m'munda, Njira zotsatirazi ziyenera kuperekedwa kuti zigwiritsidwe ntchito kutentha kwapakati, kupanikizika, kusiyana kwapakati ndi zina pamene valavu ya fluorine yokhala ndi anti-corrosion valve imasankhidwa: 1, valavu ya pulasitiki yokhala ndi fluorine yokhala ndi kutentha kwapakati: Gulu lathu la mitundu yosiyanasiyana ya mavavu apulasitiki okhala ndi fluorine, kugwiritsa ntchito pulasitiki ya fluorine ndi F46 (FEP), kugwiritsa ntchito kutentha kwapakati sikungadutse 150 ℃ (kutentha kwapakati kumatha kukhala 150 ℃ kwakanthawi kochepa, kutentha kwanthawi yayitali kuyenera kuwongoleredwa mu 120 ℃), apo ayi, zigawo za valve zomwe zimayika F46 ndizosavuta kufewetsa, kupindika, zomwe zimapangitsa kuti valavu itsekedwe undead, kutayikira kwakukulu. Ngati kutentha kwa sing'anga yogwiritsidwa ntchito ndi pansi pa 180 ℃ kwa nthawi yochepa, ndipo kutentha kuli pansi pa 150 ℃ kwa nthawi yaitali, pulasitiki yamtundu wina ikhoza kusankhidwa; PFA, koma yokhala ndi pulasitiki ya PFA fluorine ndiyokwera mtengo kuposa yokhala ndi F46 pamtengo. 2, musakhale ndi zokakamiza zoipa. Vavu ya pulasitiki yokhala ndi fluorine iyenera kupewa kugwiritsa ntchito kukakamiza koyipa mu payipi, ngati pali kupanikizika koyipa, kosavuta kupangitsa kuti pulasitiki ya fluorine yomwe ili mumtsempha wa valve imayamwa (ng'oma kunja), kupukuta, kumapangitsa kuti valve itseguke ndikutsekeka. . 3, kuthamanga, kuthamanga kusiyana kuyenera kuyendetsedwa mumtundu wovomerezeka. Makamaka ma bellows seal okhala ndi fluorine pulasitiki yowongolera valavu, valavu yapadziko lonse lapansi. Chifukwa mavuvu amapangidwa ndi zida za tetrafluoric, kupsinjika ndi kupanikizika kumakhala kwakukulu, komwe kungayambitse kuphulika kwa mavuvu. Bellows chisindikizo alimbane fluorine pulasitiki yoyang'anira valavu, kugwiritsa ntchito chikhalidwe kuthamanga, kuthamanga kusiyana ndi lalikulu, akhoza kusinthidwa PTFE kulongedza chisindikizo. 4. Sing'anga ya valavu ya pulasitiki yokhala ndi fluorine sayenera kukhala ndi tinthu tating'ono tolimba, makhiristo, zonyansa, ndi zina zotero, kuti zisawonongeke pachimake cha valve ndi mpando wa valve wokhala ndi pulasitiki wosanjikiza wa fluorine kapena mavuvu a PTFE potsegula ndi kutseka. Sing'anga imakhala ndi tinthu tolimba, makhiristo, zonyansa, kusankha, spool, mpando ungagwiritsidwe ntchito ku Hastelloy. 5, yokhala ndi valavu yoyang'anira pulasitiki ya fluorine iyenera kukhala molingana ndi kayendedwe kofunikira (mtengo wa Cv) kusankha kolondola kwa kukula kwa valavu. Mukasankha, malinga ndi kufunikira kwa magalimoto (Cv) ndi magawo ena aukadaulo amawerengedwa kukula kwa valavu kuyenera kusankhidwa ndi kutsegulidwa kwa valavu, monga kukula kwa valavu yayikulu kwambiri, kumapangitsa kuti valavu ikhale yotseguka kwa nthawi yayitali. Kuthamanga kwa nthawi, pansi pa zovuta zazing'ono komanso zapakatikati, zosavuta kupanga valavu pachimake ndi ndodo ya valavu ndi mphamvu ya atolankhani ndikupanga valavu kugwedezeka, Ndodo yapakati pakatikati kwa nthawi yaitali pansi pa zotsatira, ngakhale kupanga tsinde la valve kusweka. Ogwiritsa ntchito posankha mitundu yonse ya ma valve a pulasitiki okhala ndi fluorine, ayenera kukhala momwe angathere kuti amvetsetse, adziwe kugwiritsa ntchito zipangizo zamakono, kuti asankhe, agwiritse ntchito bwino, apititse patsogolo moyo wautumiki wa valve. Zikafika pamlingo waukadaulo, ziyenera kuperekedwa kwa wopanga, ndipo zotsutsana nazo ziyenera kutengedwa kuti athetse vutoli polumikizana limodzi.
