Cholinga chogwiritsa ntchito ma valve owunika ndikuletsa kuyenda kwa sing'anga, makamaka potumiza kunja kwa mpope kuti muyike ma valve owunika.Kuphatikiza apo, ma valavu oyendera ayenera kuyikidwa pamalo otuluka a compressor.Kawirikawiri, ma valve owunika ayenera kuikidwa mu zipangizo, mayunitsi kapena mizere kuti atetezere media reflux.
Mavavu okwera okwera nthawi zambiri amagwiritsidwa ntchito m'mimba mwake ya 50mm yopingasa mapaipi.Ma valve owongolera molunjika amatha kuyikidwa mumizere yopingasa komanso yowongoka.Vavu yapansi nthawi zambiri imayikidwa mu chitoliro choyimirira cha polowera, ndipo sing'angayo imayenda kuchokera pansi kupita pamwamba.
Swing check valve ikhoza kupangidwa kuti ikhale yogwira ntchito kwambiri, PN mpaka 42MPa, ndipo DN ikhoza kukhala yaikulu kwambiri, mpaka 2000mm.Malinga ndi zinthu za chipolopolo ndi chisindikizo, chitha kugwiritsidwa ntchito pa sing'anga iliyonse yogwira ntchito komanso kutentha kulikonse.Chapakati ndi madzi, nthunzi, gasi, sing'anga zowononga, mafuta, chakudya, mankhwala ndi zina zotero.Kutentha kogwira ntchito kwa sing'anga kuli pakati pa -196 ℃ ndi 800 ℃.
Mavavu oyendera ma swing nthawi zambiri amayikidwa mumizere yopingasa, koma amathanso kuyika mizere yowongoka kapena yokhotakhota.
Vavu yoyang'ana gulugufe ndiyoyenera kutsika pang'ono komanso m'mimba mwake yayikulu, ndipo nthawi zoikamo ndizochepa.Chifukwa kuthamanga kwa gulugufe cheke valavu sangakhale mkulu kwambiri, koma awiri mwadzina akhoza kukhala lalikulu kwambiri, akhoza kufika kuposa 2000mm, koma kuthamanga mwadzina ndi pansi 6.4mpa.Mavavu agulugufe amatha kupangidwa kukhala mtundu wopindika, womwe umayikidwa pakati pa ma flange awiri a payipi, pogwiritsa ntchito mawonekedwe olumikizirana.
Ma valve owunika agulugufe amatha kukhazikitsidwa pamzere wopingasa, woyima kapena wokhotakhota.
Diaphragm check valve ndiyosavuta kupanga mapaipi omenyera madzi, diaphragm imatha kukhala yabwino kwambiri kuthetsa kumenyedwa kwamadzi kwapang'onopang'ono.Chifukwa kutentha kwa ntchito ndi kugwiritsa ntchito mphamvu ya diaphragm cheke valavu ndizochepa ndi zinthu za diaphragm, nthawi zambiri zimagwiritsidwa ntchito paipi yotentha yotsika, makamaka yoyenera chitoliro chamadzi.General sing'anga kutentha ntchito pakati -20 ~ 120 ℃, ntchito kuthamanga <1.6mpa, koma diaphragm cheke valavu akhoza kuchita awiri lalikulu, DN mpaka 2000mm pamwamba.
Valavu yoyang'ana diaphragm chifukwa cha ntchito yake yabwino yopanda madzi, kapangidwe kake kosavuta, mtengo wotsika wopanga, kotero m'zaka zaposachedwa, ntchito zambiri.
Chifukwa chisindikizo ndi mpira wokutidwa ndi mphira, valavu yoyang'ana mpira imakhala ndi ntchito yabwino yosindikiza, ntchito yodalirika komanso kukana kwamadzi.Ndipo chifukwa chisindikizocho chikhoza kukhala mpira umodzi, ndipo chingapangidwe kukhala mipira yambiri, kotero kuti chikhoza kupangidwa kukhala chachikulu.Koma chisindikizo chake chophimbidwa ndi mphira dzenje lozungulira, losayenerera mapaipi othamanga kwambiri, oyenera mapaipi apakati komanso otsika.
Chifukwa chipolopolo cha valavu yozungulira cheke chikhoza kupangidwa ndi chitsulo chosapanga dzimbiri, ndipo gawo lopanda kanthu la chisindikizocho limatha kuphimbidwa ndi mapulasitiki a uinjiniya a polytetrafluoroethylene, atha kugwiritsidwanso ntchito popanga ma media ambiri owononga.
Mtundu uwu wa cheke valavu ntchito kutentha pakati -101 ℃ kuti 150 ℃, kuthamanga kwake mwadzina ≤4.0MPa, m'mimba mwake mwadzina osiyanasiyana pakati 200 ~ 1200mm.
Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
Zogulitsa zazikulu:Valve ya Butterfly,Valve ya Mpira,Chipata cha Chipata,Onani Vavu,Globe Vavlve,Y-Strainers,Electric Acurator,Pneumatic Acurators .
