Chithunzi cha CHV402-PN16
Valavu yoyendera imagwiritsidwa ntchito m'njira zosiyanasiyana monga nthunzi, madzi, nitric acid, mafuta, media oxidizing media, acetic acid, ndi urea. Izi nthawi zambiri zimagwiritsidwa ntchito m'mafakitale, mafuta, feteleza, mankhwala, magetsi, ndi mafakitale ena. Komabe, ma valve awa ndi oyenera kuyeretsedwa osati kwa ma mediums omwe ali ndi zonyansa zambiri. Ma valve awa samalimbikitsidwanso kwa ma mediums omwe akugwedeza. Ndife amodzi mwa opanga ma valve omwe amapanga ma valve apamwamba kwambiri.
Chisindikizo cha milomo chomwe chili pa diski chimatsimikizira kuti sichimamasuka.
Kapangidwe ka disc kapena bonnet kumapangitsa kukhala kosavuta kukonza
Chimbale pa valavu chimatha kusuntha pang'ono molunjika komanso mopingasa kutseka bwino.
Pamene disk ndi yopepuka kulemera, imafunika mphamvu yochepa kuti itseke kapena kutsegula valve.
Hinge yozungulira tsinde yokhala ndi mafupa amphamvu imatsimikizira kulimba kwa valve.
Mavavu amtundu wa swing amapangidwa kuti ateteze sing'anga mu chitoliro kuti isabwerere chammbuyo. Kupanikizika kukakhala zero, valavu imatseka kwathunthu, zomwe zimalepheretsa kubwereranso kwazinthu mkati mwa payipi.
Chisokonezo ndi kutsika kwamphamvu kwa mavavu amtundu wa swing-wafer ndi otsika kwambiri.
Mavavuwa ayenera kuikidwa mopingasa mu mapaipi; komabe, amatha kuyikanso molunjika.
Yokhala ndi chipika cholemetsa, imatha kutseka payipi mwachangu ndikuchotsa nyundo yamadzi yowononga
Mtunduwu ukhoza kupangidwa kuti ugwirizane ndi ntchito yanu, yomanga thupi, zinthu, ndi zina zowonjezera zomwe zimakongoletsedwa kuti zikwaniritse zosowa zanu. Pokhala wovomerezeka wa ISO 9001, timatengera njira zowonetsetsa kuti zinthu zili bwino kwambiri, mutha kutsimikiziridwa kuti ndinu odalirika komanso osindikiza ntchito kudzera mu moyo wapangidwe wa katundu wanu.
Kupanga ndi Kupanga Kugwirizana ndi EN12334, BS5153
Makulidwe a Flange Amagwirizana ndi EN1092-2 PN16
Kukula kwa nkhope ndi nkhope Kugwirizana ndi EN558-1 Mndandanda 10, BS5153

Makanema akamapopedwa kuchokera pamadzi oyamwa kupita kumalo otayira, kuthamanga kwapambuyo kumakhala kotheka kuchitika mpopeyo ikayimitsidwa. Ma valve owunika amagwiritsidwa ntchito kupewa izi. Mtundu wa valve womwe umagwiritsidwa ntchito kwambiri pa izi ndi valavu ya phazi.
Valavu yowunikira imakhala ndi madoko awiri - cholowera ndi chotulukira - ndi njira yotsekera / yotseka. Makhalidwe apadera a ma check valves omwe amawasiyanitsa ndi mitundu ina ya ma valves monga mpira ndi butterfly valves ndikuti, mosiyana ndi ma valve omwe amafunikira mtundu wina wa actuation kuti agwire ntchito, ma check valves amadziyendetsa okha. Ma valve owunika amagwira ntchito okha, kudalira kukakamiza kosiyana kuti azitha kuwongolera. Pamalo awo osakhazikika, ma cheki ma valve amatsekedwa. Pamene zofalitsa zimalowa kuchokera ku doko lolowera, kupanikizika kwake kumatsegula njira yotseka. Pamene kuthamanga kwa mpweya kumatsika pansi pa kuthamanga kwa kutuluka chifukwa cha kutuluka kwa madzi kutsekedwa, kapena kupanikizika kumbali yotuluka kumakhala kwakukulu pazifukwa zilizonse, njira yotseka nthawi yomweyo imatseka valve.
