He aha te Takirere Whakamutu (SDV)?

He aha te meaTakirere Whakamutu

He Takirere Whakamutu (e mōhiotia ana ko te SDV, Emergency Shutdown Valve rānei, ESV, ESD,ESDV) he takirere whakaoho i hangaia hei aukati i te rere o tētahi wai morearea ina kitea he huihuinga morearea.

Ka whakaratohia e tēnei he parenga mai i ngā kino ka pā ki te tangata, ki ngā taputapu, ki te taiao rānei. Ko ngā takirere whakaweto he wāhanga o tētahi Pūnaha Taputapu Haumaru. Ko te tukanga o te whakarato parenga haumaru aunoa ina kitea he kaupapa morearea ka kiia ko te Haumaru Mahi.

Ngā momo takirere whakaweto

Mō ngā wai, he mea whakarewa te whakanohongā takirere pōroe whakamahia ana hei takirere kati (SDV). Ko te whakamahinga o ngā takirere pōro noho-whakarewa ka iti ake ngā utu katoa ina whakaarohia te ngaronga o te whakaputanga me te taonga, me ngā utu whakatika takirere e puta mai ana i te whakamahinga o ngā takirere pōro noho-ngohengohe he iti ake te utu tīmatanga.

Ko ngā takirere rere tika, pērā i ngā takirere pōro poro-hurihuri, he takirere whakaora-teitei te nuinga. Ko ngā takirere whakaora-teitei he takirere e ngaro ana te iti o te kaha nā te iti o te aueue o te rere. He tika ngā ara rere. Ko ngā takirere whakahaere hurihuri, te takirere pūrerehua me ngā takirere pōro he tauira pai.

Mō te kati i te hau e tomo ana, e rua ngā momo rerekē e whakamahia whānuitia ana, arā, ko ngā takirere pūrerehua me ngā takirere keti hurihuri, ko ngā takirere porotiti rānei. Nā te mea mā te kōpeketanga o te wahie e whakakā ai ngā miihini tīhiera, kaua mā te whakakā hiko, kāore e mutu te oma o te miihini mā te kati i te pūtake wahie ki te miihini tīhiera.

Ina kitea he hauwaiwai o waho, pērā i te hau methane, i te āhuarangi, ka taea te mimiti ki roto i te miihini tīhiera ka tere rawa, ka tere rawa rānei te hurihanga, ka arahi pea ki te pakaru kino me te pahūtanga. Ina whakahohea, ka aukatihia te rere o te hau e ngā takirere ESD, ā, ka ārai i ēnei pakaru.

Ngā momo Whakaoho

I te mea he wāhanga o te SIS ngā takirere whakaweto. Me whakahaere te takirere mā te whakamahi i tētahi kaiwhakaoho.

Ko ēnei pūwhakaoho he momo mana wai haumaru kore e rahua.

Ko ngā tauira noa o ēnei ko:

Pūangi hau

Puoto waipēhi

Pūwhakaoho hiko-waipēhi

Haunga te momo wai, he rerekē anō hoki te āhua o te penapena pūngao o ngā actuator hei whakahaere i te takirere ina hiahiatia:

Puoto mahi kotahi– Te hokinga mai rānei o te puna, te wāhi e rongoatia ai te pūngao mā te puna kua pēhia

Puoto mahi takirua– Ka rongoatia te pūngao mā te whakamahi i te nui o te wai kua kōpeketia

Ko te momo whakaoho e hiahiatia ana ka whakawhirinaki ki te tono, ki ngā whakaurunga o te papa me te wāhi e wātea ana, ahakoa ko te nuinga o ngā whakaoho e whakamahia ana mō ngā takirere whakamutu he momo puna whakahoki nā te mea he haumaru kore ngā pūnaha puna whakahoki.

Te Ine i te Mahi

Mōngā takirere whakawetoHei whakamahi i ngā pūnaha taputapu haumaru, he mea nui kia mōhio ka taea e te takirere te whakarato i te taumata mahi haumaru e hiahiatia ana, ā, ka mahi te takirere ina hiahiatia.

Ko te taumata mahi e hiahiatia ana ka whakatauhia e te Taumata Haumarutanga (SIL). Hei piri ki tēnei taumata mahi, me whakamātautau te takirere. E rua ngā momo tikanga whakamātautau e wātea ana, arā,Whakamātautau taunakitanga

– He whakamātautau ā-ringa e āhei ai te kaiwhakahaere ki te whakatau mēnā kei roto te takirere i te āhua "hou tonu" mā te whakamātautau mō ngā momo rahunga katoa, ā, me whakaweto te tipuWhakamātautau Tātaritanga

– He whakamātautau aunoa ipurangi e kitea ai te ōrau o ngā momo rahunga pea o te takirere kati. Ko tētahi tauira o tēnei mō te takirere kati ko te whakamātautau whiu ā-wāhanga. He tauira o tētahi taputapu whakamātautau whiu ā-wāhanga miihini.
