He aha te API 609 Butterfly Valve?
Ngā Takirere Pūrerehua API 609He takirere ahumahi ēnei i hangaia kia rite ki ngā paerewa o te American Petroleum Institute (API). Ka tukuna e rātou he hiri tino pai, he ātete ki te waikura, me te pono o te pēhanga i roto i ngā paipa hinu, hau, matū, me te petrochemical. Ka tutuki i ēnei takirere pūrerehua mahi-teitei ngā paearu pakari o te ao mō te haumaru me te whai hua.
Te Mārama ki ngā Paerewa API 609
Ko te API 609 te paerewa hoahoa mō ngā takirere pūrerehua paerewa o Amerika i whakaputaina e teTe Whare Hinu o AmerikaKo tōna ingoa katoa ko "Ngā Takirere Pūrerehua: Momo Takirua, Momo Tuka me te Momo Wafer". Ko te putanga hou rawa ko te putanga 2021 i tēnei wā."
Ko te putanga paerewa hou o te API 609 ko te API 609-2021 (Putanga 8), e whakahou ana i ngā paerewa hoahoa takirere pūrerehua, e whakawhānui ana i ngā whakatakotoranga mō ngā takirere pūrerehua flange takirua, lug me te wafer, ā, e tāpiri ana i ngā rarangi mō ngā takirere pūrerehua butt-weld.
Ihirangi whakahōu paerewa
•Takirere pūrerehua whakarewa pūmau: Ka tāpirihia e te putanga 2021 ngā whakaritenga hoahoa mō ngā takirere pūrerehua whakapiri-tua i runga i te pūtake taketake, ka whakarei ake i ngā whakaritenga paerewa mō ngā tikanga hononga takirere pūrerehua.
;•Te whakatikatika i ngā kupu hangarauKua whakatikatikaina ētahi whakatakotoranga hangarau kia rite ki ngā mahi a te umanga, engari kāore ngā taipitopito hangarau motuhake i whakaaturia i roto i ngā mōhiohio tūmatanui.
Ko ngā kaupapa matua o te paerewa API 609 e kapi ana i ngā hoahoa takirere pūrerehua takirua-rere, momo-tu, me te wafer. E whakamārama ana tēnei paerewa i:
1. Ngā Whakaritenga Hoahoa:Te arotau i ngā āhuatanga wai kia iti ai te ātete rere me te whakahaere tika.
2. Rauemi me te HangangaNgā whakaritenga mō ngā tinana takirere, ngā kōpae (ngā pereti pūrerehua), ngā kakau, me ngā hiri.
3. Ngā Tikanga Whakamātautau:Ngā whakamātautau pēhanga, hiri, me te rere e hiahiatia ana hei whakaū i te kounga.
4. Aratohu Tiaki:Ngā tikanga mō te tirotiro, te whakahinuhinu, me te whakatika.
Te Mahi a ngā Takirere Pūrerehua
A takirere pūrerehuaKa huri te kōpae o 's 90° huri noa i tōna tuaka hei whakahaere i te rere. Ngā āhuatanga matua:
•Tūnga Tuwhera: Kōpae whakarara ki te rere (he iti rawa te hekenga pēhanga).
•Tūnga Kua Kati: Kōpae poutū ki te rere (kati mirumiru).
•Whakaoho: E whakamahi ana i ngā kakau ā-ringa, i ngā kaiwhakahaere taputapu, i ngā pūnaha aunoa rānei (hauā/hiko).
Ngā Wāhanga Matua o ngā Takirere Pūrerehua
1. Tinana Takirere
He hoahoa porotakaroa kiato; e wātea ana i ngā momo angiangi, pūtu, me ngā momo tapawhā rānei.
2. Kōpae (Pereti)
He pereti angiangi, porowhita (he kowiri tira noa) hei whakahaere rere.
3. Kākano
