API 6D/API 608 Te Whakarewa/Te Hanga Pēhanga Teitei Bw Mānu/Trunnion Dbb Ā-ringa/Hiko/Haumākū Cryogenic Āhua-Poro Tauhou
He aha te takirere pōro trunnion DBB?
Takirere pōro trunnion DBBhe takirere pōro i hangaia motuhake.
Mō te pūnaha poraka takirua me te pūnaha takirere toto, e rua ngā whakamāramatanga e API6D me OSHA.
Ka tautuhia e te OSHA hetakirere pōro trunnion DBBKo te pūnaha he "katinga o tētahi raina, paipa rānei mā te katinga me te raka, te tāpiri rānei i tētahi tohu ki ngā takirere e rua, mā te whakatuwhera me te raka, te tāpiri rānei i tētahi tohu ki tētahi takirere waikeri, ki tētahi takirere hau rānei i te raina i waenganui i ngā takirere e rua kua kati".
teTakirere pōro trunnion NORTECH DBBi hangaiaMā te whakakotahi i ngā takirere e rua ki te tinana kotahi, ka whakaitihia te taumaha me ngā ara turuturu pea e te hoahoa takirere-rua, ā, ka tutuki hoki i ngā whakaritenga a te OSHA mō te aukati takirua me te toto.
E whakamāramahia ana e te API 6D te Pūnaha takirere pōro trunnion DBB hei "takirere kotahi me ngā mata nohoanga e rua, i te tūranga kati, ka whakarato i te hiri ki te pēhanga mai i ngā pito e rua o te takirere me te tikanga ki te tuku/whakaheke toto i te kōhao i waenganui i ngā mata nohoanga."
Ngā āhuatanga matua o te takirere pōro trunnion DBB
Wāhanga Kotahitakirere pōro trunnion DBB Ka whakaratohia he aukati takirua me te whakaheke toto i roto i te takirere kotahi. Ka taea e tēnei momo te wehe i ngā paipa i ngā taha e rua o te takirere hei whakaputa/whakaheke toto i te kōhao takirere i waenganui i ngā nohoanga.
Mā te whakamahi i tētahi pūnaha takirere poraka takirua me te takirere toto kotahi, ka penapenahia te wā tāutanga, te taumaha o te pūnaha paipa, me te wāhi hoki e toru. He painga whakahaere anō hoki tō tēnei hoahoa,
- He iti ake ngā ara turuturu pea i roto i te wāhanga poraka takirua me te wāhanga toto o te paipa.
- Kei roto i te kotahi te wāhi e whakanohoia ana ngā wāhanga takirere katoa, ā, ka tino whakaitihia te wāhi e hiahiatia ana mō te tāutanga, ā, ka wātea ake te wāhi mō ētahi atu taputapu nui.
- E hiahiatia ana he wā poto ake mō te tango wai.
takirere pōro trunnion DBB He huinga o tētahi, neke atu rānei o ngā takirere poraka/wehewehe, ko te tikanga he takirere pōro, me tētahi, neke atu rānei o ngā takirere toto/pūhau, ko te tikanga he takirere pōro, he takirere ngira rānei. Ko te kaupapa o te pūnaha takirere poraka me te takirere toto he wehe, he ārai rānei i te rere o te wai i roto i te pūnaha kia kore ai te wai mai i te taha whakarunga e tae atu ki ētahi atu wāhanga o te pūnaha kei raro iho. Mā tēnei ka taea e ngā kaihangarau te toto, te whakaputa rānei i te wai e toe ana mai i te pūnaha i te taha whakarunga kia taea ai te mahi i ētahi momo mahi (tiaki/ whakatika/ whakakapi), te tango tauira, te hurihanga rere, te werohanga matū, te tirotiro i te pai o te turuturu me ētahi atu.

Whakaaturanga Hua: DBB trunnion ball valve
Te tono o te takirere pōro trunnion DBB
Ngā takirere pōro trunnion DBBe whakamahia ana i roto i te umanga hinu me te hau, engari he āwhina anō hoki i roto i te maha atu o ngā umanga. E whakamahia ana i ngā wā e hiahiatia ana te whakaheke toto i te kōhao takirere, i ngā wā e hiahiatia ana te wehe i ngā paipa hei tiaki, i ētahi atu āhuatanga rānei:
- Ārai i te poke o te hua.
- Tangohia ngā taputapu mai i te ratonga hei horoi, hei whakatika rānei.
- Te whakatikatika i te mita.
- Wehea ngā taputapu pēnei i ngā tohu pēhanga me ngā ine rīwhi.
- Te mamaoa tukatuka tuatahi.
- Whakawetohia, ā, whakapūhauhia ngā taputapu ine pēhanga.
