Utu wheketere DN50-DN2000 Noke taputapu rapa-raina rewharewha takirere mo te hoko
He aha te rapa rewharewha rewharewha?
Rererere rererere kua rapahia e kiia ana ko te "concentric", "raina rapa" me te "noho rapa" rewharewha rewharewha, he nohoanga rapa (he kaha ranei) i waenga i te diameter o waho o te kōpae me te pakitara o roto o te takirere.Ka whakamahia ano te paera rerehua hei reera rere, ki te kore te kopae e huri ki te hurihanga hauwhā, ko te tikanga ka tuwhera te wahanga, ka taea e tatou te whakahaere i te rere o nga wai ma nga momo koki tuwhera.
Rererere rererere kua rapahia,Ko te tikanga ka whakamahia ki te waahi kei te pito o te putorino te putunga na te mea karekau he flange tuarua hei mau i nga tiu.Engari, ka makahia nga lugs ki runga i te takirere me nga kohao paopao e rite ana ki te tauira raka mo te rahi me te whakarōpū pehanga o te flange.Ka tukuna nga raka ki roto i nga kohao flange ka miro ki nga kohao tap o te raka.
Rererere rererere kua rapahia,te hoahoa tino kiato me te kanohi poto ki te kanohi.he pai ki waenga i nga kopa e rua, me nga tii e haere ana mai i tetahi flange ki tetahi.Ka mau te paera ki te waahi ka hirihia ki te peera e te awangawanga o nga studs.Ko te momo resilient resilient resilient butterfly valve lug he maamaa, he kore tiaki, he utu-utu, he otinga pono ki nga momo tono.
Ko nga ahuatanga matua o te momo lug resilient butterfly valve lug NORTECH
Ko nga ahuatanga matua oRererere rererere kua rapahia
- ISO 5211 flange runga he pai mo te ngawari aunoatanga me te whakahou i te kaiwhakaari.
- Ko nga taipana whakahaere iti ka puta he mahinga ngawari me te kowhiringa ohaoha.
- Ko nga peera raina PTFE kua hangaia mo te aukati me te kakahu, kaore e hiahiatia te whakahinuhinu.
- Kua whakauruhia he raina ki te tinana, he ngawari ki te whakakapi, kaore he waikura i waenga i te tinana me te raima, he pai mo te mutunga o te whakamahi raina.
- Ko te hanga kiato he iti te taumaha, he iti ake te waahi ki te rokiroki me te whakaurunga.
- Te tuunga o te poukau, 100% te piri mirumiru ahu-rua, e pai ai te whakauru ki nga huarahi katoa.
- He iti te atete ki te rere o te tinana whanau katoa
- Kaore he kohao i roto i te rerenga rerenga, he maamaa te horoi me te whakakino mo te punaha wai inu etc.
