1.Rererere momo angiangi
Ko te kōpae o teangiangi pūrerehua takirereka whakauruhia ki te ahunga diameter o te paipa.Kua tino tuwhera te paera.
He ngawari te hanganga o te wafer butterfly valve, he iti te rahi me te taumaha marama.E rua nga momo hiri o te hiri rekereke: hiri rapa me te hiri whakarewa.Ka taea te whakakikoruatia te mowhiti hiri ki runga i te tinana takirere, ka piri ranei ki te taha o te kōpae.
2. Rererererere rewharewha takirere
Ko te riu pererere he hanganga pereti poutū, ko te kakau takirere ko te mowhiti hiri o te whakaurungawhakarewa maataki maataki maataki.
He hanganga hiato o te pereti kauwhata ngawari me te pereti kowiri tira, kua whakauruhia ki runga i te tinana takirere, a ko te mata hiri o te kopae rerererere kei runga i te kowiri tira.Ko te mowhiti hiri o te hiri hiri ngawari he mea hanga ki te rapa nitrile ka whakauruhia ki runga i te pereti papanga.
3. Huka rererererehu takirere
4. Rererererere paiherea takirere
Rererererere paihereaKo te ahua o te rewharewha hiri kore-hiri, e whakamahia whanuitia ana i roto i nga pipelines me te pāmahana reo ≤300 ℃ me te pehanga ingoa o 0.1Mpa i roto i te tukanga whakaputa o nga taonga hanga whare, whakarewa, maina,mana hiko, etc., hei hono, hei whakatuwhera me te kati, hei whakatika ranei i te nui o te reo.
Hiko whakahaere rererererere takirerehe momo hiko hiko me te hiko whakahaere hiko.Ko nga tikanga hononga matua ko: momo flange me te momo angiangi, he waahanga mahi nui i roto i te waahi o te whakahaere aunoatanga ahumahi.
E rua nga waahanga matua mo te whakaurunga o te reera reera hiko hiko: Ko te tuunga whakaurunga, te teitei, me te ahunga o te kokoru me te putanga me tutuki nga whakaritenga hoahoa.
Kia mahara ko te ahunga o te rere reo kia rite ki te ahunga o te pere kua tohua ki te tinana takirere, kia u, kia piri te hononga.
Ko te hiko retere rererererere takirere me tirotirohia i mua i te whakaurunga, me te papa ingoa o te takirere kia rite ki te paerewa motu "General Valve Mark" GB12220.
Mo nga reera me te pehanga mahi nui ake i te 1.0MPa me te mahi tapahi i runga i te putorino matua, me mahi nga whakamatautau mahi kaha me te piri i mua i te whakaurunga.
Ka taea te whakamahi i muri i te tohu.I te wa o te whakamatautau kaha, ko te pehanga whakamatautau he 1.5 nga wa te pehanga ingoa, a ko te roanga kaore e iti iho i te 5 meneti.Me whai tohu te anga takirere me te tarapi me te kore e pakaru.
