Taha Whakanohoia Takiwa Hawhe-Poro Valves
Ngā āhuatanga
▪ Ko te hoahoa hanganga rereke ka whakaiti i te taipana whakatuwhera, ka whakaheke i te waku o te mata hiri me te whakaroa i te oranga o te mahi.
▪ He iti te parenga o te wai, a, he rite te whakarea parenga ki tera o te wahanga paipa he rite te roa.
▪ Ka taea te whakamahi i te rapa hipoki, i te tuuru whakarewa ranei hei whakarite ka taea te whakamahi i te takirere i roto i nga ahuatanga mahi rereke.
▪ Ma te hiri piri me te kore e pakaru mo te tuku hau kino.
▪ Te pehanga whakamatautau:
Pehenga Whakamatau Anga 1.5 x PN
Hiiri Whakamatau Whakamatau 1.1 x PN
▪ Ko te kowhiringa o nga takirua hiri hiri me te koranu rereke (te poi whakakotahi ranei) mo te papa ka taea te whakamahi mo nga tikanga mahi me te aukati kakahu, te aukati waikura, te parenga teitei o te pāmahana me nga whakaritenga hiri kaha:
1. Rahi whakamahia noa: Rahi DN40 ~ 1600, e tika ana mo te maimoatanga parakaingaki, te penupenu, te whakamahana taone me etahi atu waa me nga whakaritenga tino.
2. Waea motuhake mo te ahumahi petrochemical: Rahi DN140 ~ 1600. He pai mo te hinu hinu, te hinu taimaha me etahi atu hua hinu, te ngoikore ngoikore me te rua-waahanga-rua-waahanga rerenga rerenga i roto i te ahumahi matū.
3. Vale motuhake mo te hau: Rahi DN40 ~ 1600, e pa ana ki te mana tuku o te hau, te hau taiao me te hau liquefied.
4. Takiwa motuhake mō te slurry: Rahi DN40 ~ 1600, e hāngai ana ki te kawe pipeline ahumahi ki te rerenga whātioatanga ranei tauine i roto i te wai, me te totoka rua-wahanga rere whakauru ranei tauhohenga matū i roto i te kawe wai.
5. Waea motuhake mo te pungarehu waro pupuhi: Rahi DN140 ~ 1600. E tika ana ki te whakahaere i te mana o te tipu hiko, te tangohanga o te waipēhi waipēhi, te paipa whakawhiti hau ranei.

Kaupapa
Taupānga
▪ Ka whakamahia e te takirere hemispherical hiako te tinana takirere pokanoa, te poi pokanoa me te nohoanga takirere.Ka huri te rakau takirere, ka whakateka aunoa ki te ara noa.Ko te nui ake o te kati, ka kaha ake i roto i te mahi kati, kia tino tutuki ai te kaupapa o te hiri pai.
▪ Ko te poi o te paera kua tino wehea mai i te tuuru takirere, ka whakakore i te kakahu o te mowhiti hiri me te wikitoria i te raru e mau tonu ana te nohoanga o te poi poi tuku iho me te mata hiri o te poi.Ko nga mea rapa kore-whakarewa kua mau ki roto i te nohoanga whakarewa, a, ka tiakina pai te mata whakarewa o te nohoanga takirere.
▪ He pai rawa tenei takirere mo te ahumahi rino, te ahumahi konumohe, te muka, nga matūriki totoka moroiti, te penupenu, te pungarehu waro, te hinu hinu me etahi atu panui.
