Kuyika ndi kuyika kwa ma valve cheke
Chidule cha valve cheki
Ma valve owunikira ndi chida chofunikira chowongolera madzimadzi, chomwe chimagwiritsidwa ntchito kwambiri pantchito zosungira madzi, ma petrochemicals, kuteteza chilengedwe ndi zina.Ntchito yake yayikulu ndikuletsa kubwereranso kwa media ndikuwonetsetsa kuyenda kwa njira imodzi yamapaipi.Kuyika ndi kuyika kwa ma valve cheke kumakhudza mwachindunji ntchito yawo ndi moyo wautumiki.Nkhaniyi ifotokoza zamitundu yosiyanasiyana ya ma cheki ma valve ndi malingaliro awo pakuyika kwawo mwatsatanetsatane.
Mitundu yayikulu ya ma cheke
Malinga ndi kapangidwe kake ndi mfundo yogwirira ntchito, ma valavu amacheke amagawidwa m'mitundu iyi:
1. Vavu yoyang'ana mbale ziwiri
2. Kwezani valavu yowunika
3. Valovu yowunika mpira
4. Swing valve check valve
Kuyika kolowera mtundu wa valavu yoyendera
1. Kuyika kopingasa: Amatanthauza njira yokhazikitsira valavu yoyang'ana paipi yopingasa, yomwe nthawi zambiri imagwiritsidwa ntchito pamapaipi otsika kwambiri, ndipo m'mimba mwake wa valavu ya valve ndi yokulirapo kuposa kukula kwa payipi.
2. Kuyika koyima: Amatanthauza njira yokhazikitsira valavu yoyang'ana paipi yoyima, yomwe nthawi zambiri imagwiritsidwa ntchito pamapaipi othamanga kwambiri, ndipo m'mimba mwake wa valavu ya valve ndi yocheperapo kusiyana ndi m'mimba mwake.
1. Valovu yoyang'ana ma disc awiri
Dual disc check valve: nthawi zambiri amakhala ndi ma disks awiri a semicircular omwe amayenda mozungulira tsinde perpendicular mpaka pakatikati pa kutuluka kwa madzimadzi.Ma valve oyendera ma disc awiri ndi mavavu ophatikizika okhala ndi utali wochepa.Iwo anaika pakati flanges awiri.Nthawi zambiri amakhala omangika kapena opindika.Nthawi zambiri amagwiritsidwa ntchito pamapaipi okhala ndi mainchesi ≤1200mm.
Kuyika kolowera kwa Double-disc check valve
Ma valve oyang'ana ma disc awiri amatha kuyikidwa molunjika kapena molunjika mupaipi.Kuyika kopingasa kungapangitse kutsegula ndi kutseka kwa valavu ya cheke yomwe imakhudzidwa ndi mphamvu yokoka, kupangitsa kuti liwiro lake lotsegula likhale lokhazikika komanso kuchepetsa kuchepetsa kuthamanga kwa mapaipi.Kuyika kwa vertical kungapangitse valavu kukhudzidwa ndi mphamvu yokoka ikatsekedwa, kupangitsa chisindikizo chake kukhala cholimba.Kuonjezera apo, kuyika koyima kungalepheretse cheke cha valve kuti chisagwedezeke mofulumira pakusintha kwamadzimadzi, kuchepetsa kugwedezeka kwa diski ndi mpando wa valve, ndikuwonjezera moyo wautumiki wa valve.
2. Swing valve check valve
Swing ma valvekukhala ndi valve disc.Pamene sing'anga ikuyenda patsogolo, valavu ya valve imakankhidwa motseguka;pamene sing'anga imayenda molowera chakumbuyo, valavu ya valavu imalowetsedwanso pampando wa valavu kuti asabwerere.Valavu yamtunduwu nthawi zambiri imagwiritsidwa ntchito m'mapaipi akuluakulu chifukwa cha mawonekedwe ake osavuta komanso otsika.
Kuyika kolowera kwa Swing check valve
Mavavu a swing cheque amatha kuyikidwa mopingasa kapena molunjika, koma nthawi zambiri amalimbikitsidwa kuti ayike mapaipi opingasa.Tiyenera kukumbukira kuti, malingana ndi momwe zinthu zilili, valavu ya swing check ingathenso kuikidwa mopanda malire, malinga ngati ngodya yoyikirayo sidutsa madigiri a 45 ndipo malo oyikapo ndi oyenerera, sichidzakhudza ntchito yotsegula ndi yotseka. wa valavu.
3. Chopingasa chokweza chekeni valavu
Disiki ya valavu ya valavu yokweza yopingasa imayenda mmwamba ndi pansi motsatira njanji yowongolera mu thupi la valavu.Pamene sing'anga imayenda patsogolo, diski ya valve imakwezedwa;pamene sing'anga imayenda mozungulira, chimbale cha valve chimagwera kumpando wa valve kuti chiteteze kubwerera.
Njira yoyika ma Horizontal lift cheque valve
Vavu yoyang'ana yokwera iyenera kuyikidwa paipi yopingasa.Chifukwa ikayikidwa molunjika, chigawo chake cha valve chimakhala chopingasa, ntchito yake yokhazikika ndi mpando wa valve imachepa pansi pa kulemera kwake, zomwe zimakhudza kusindikiza kwapakati pa valve.
4. Valovu yokweza yokwera
Kwa ofukulakukweza ma valve, mayendedwe apakati pa valve ndi ofanana ndi momwe mapaipi amayendera.Ndipo pakati pa valavu pachimake chimagwirizana ndi pakati pa njira yotuluka.
Kuyika kolowera kwa Vertical lift check valve
Ma valve owunika ayenera kuyikidwa molunjika m'mapaipi pomwe sing'anga imayenda m'mwamba, chifukwa mphamvu yokoka imathandiza kuti valavu ya valve itseke mwamsanga pamene kutuluka kwasiya.
5. Vavu yoyang'ana mpira
Valavu yowunikira mpira imagwiritsa ntchito mpira womwe umayenda m'mwamba ndi pansi m'thupi la valve.Pamene sing'anga imayenda kutsogolo, mpira umakankhidwira kutali ndi mpando wa valve, njira imatsegulidwa, ndipo sing'anga imadutsa;pamene sing'anga imayenda mozungulira, mpira umabwerera kumpando wa valve kuti uteteze kubwerera.
Kuyika kolowera kwa Ball check valve
Ma valve cheke a mpira amatha kuyikidwa pamapaipi opingasa, koma ndi oyenera kuyika molunjika, makamaka pamene sing'anga imayenda m'mwamba.Kulemera kwakufa kwa mpira kumathandiza kusindikiza valve pamene kutuluka kwasiya.
Zinthu zomwe zimakhudza kuyimitsidwa kwa ma check valve
Mukayika valavu yoyang'ana molunjika, pali zinthu zingapo zomwe ziyenera kuganiziridwa kuti zitsimikizire kuti zikugwira ntchito bwino:
1. Njira yoyenda
Pakuyika koyima, njira yoyendetsera sing'anga ndiyofunikira.Pamene ikuyenda m'mwamba, diski ya valve imatha kutsegulidwa ndi kupanikizika kwapakati, ndipo kutseka ndi mphamvu yokoka yomwe imathandiza kuti diski ya valve ibwerere pamalo ake, pamene ikuyenderera pansi, miyeso yowonjezera ingafunike kuonetsetsa kuti valve imatseka modalirika.
2. Mphamvu yokoka
Mphamvu yokoka imakhudza kutsegula ndi kutseka kwa valve.Mavavu omwe amadalira mphamvu yokoka kuti asindikize, monga mavavu aŵiri ndi okweza, amagwira ntchito bwino akamayenda chokwera chokwera.
3. Makhalidwe a media
Makhalidwe a media, monga mamasukidwe akayendedwe, kachulukidwe, ndi tinthu tating'onoting'ono, zimakhudza magwiridwe antchito a valve.Viscous kapena tinthu tating'onoting'ono tating'onoting'ono tingafunike kupangidwa mwamphamvu komanso kukonza pafupipafupi kuti valavu igwire ntchito modalirika.
4. Kuyika chilengedwe
Malo oyika, kuphatikizapo kutentha, kupanikizika, ndi kukhalapo kwa zinthu zowonongeka, zidzakhudza ntchito ndi moyo wa valve.Kusankha zipangizo ndi mapangidwe oyenerera malo enieni amatha kuwonjezera moyo wautumiki wa valve.
Ubwino ofukula unsembe cha valve valve
1. Kugwiritsa ntchito mphamvu yokoka
Pankhani yopita kumtunda kwa ma TV, mphamvu yokoka imathandiza kuti valavu itseke, imapangitsa kuti ntchito yosindikiza ikhale yabwino, ndipo sichifuna thandizo lakunja.
2. Chepetsani kuvala
Kugwiritsa ntchito mphamvu yokoka ya media ndi mbale ya valavu kutseka valavu yotsekera kungachepetse kugwedezeka, kuchepetsa kuvala, kukulitsa moyo wautumiki wa valavu, ndikuchepetsa pafupipafupi kukonza.
Kuipa kwa ofukula unsembecha valve valve
1. Kukana kuyenda
Kuyika mowongoka kungapangitse kukana kwamadzi, makamaka kwa ma valve okwera okwera, omwe amafunikira kukana osati kulemera kwa mbale ya valve, komanso kupanikizika koperekedwa ndi kasupe pamwamba pa mbale ya valve.Izi zidzapangitsa kuchepa kwa kuyenda komanso kuwonjezeka kwa mphamvu zamagetsi.
2. Chodabwitsa cha nyundo yamadzi
Pamene sing'anga imayenda m'mwamba, mphamvu ya valve yowunikira ndi mphamvu yokoka ya sing'anga idzawonjezera kupanikizika kwa payipi, zomwe zimapangitsa kuti zikhale zosavuta kuyambitsa nyundo yamadzi.
