He aha te wā whakatuwheratanga me te wā kati mō Globe Valve?

Te wā whakatuwheratanga me te wā kati o tētahitakirere porowhitaKo te roanga o te wā e neke ai te kōpae takirere mai i te kati katoa ki te tuwhera katoa, mai i te tuwhera katoa ki te kati katoa rānei. Nā te mea he kakau piki rārangi me te wira ringa maha-hurihuri, he kaiwhakaoho rānei te whakamahi a te takirere porowhita, he roa ake te wā mahi i ngā takirere pērā i ngā takirere pōro, i ngā takirere pūrerehua rānei.

Te Wā Whakatuwheratanga me te Wā Katinga Noa

①Tarere Porowhita Ā-ringa

• Ngā rahi iti (DN15–DN50):
  5–12 hēkoname te hurihanga noa o te wira ringaringa.

• Ngā rahi waenga (DN65–DN150):
  10–25 hēkonai runga i te haere o te kakau me te kaha o te kaiwhakahaere.

• Ngā rahi nui (DN200–DN350 me runga ake):
  25–60 hēkona, neke atu rānei, nā te mea he maha ngā tahuritanga e hiahiatia ana hei nuku i te kōpae.

②Taurere Porowhita Hiko Whakaohohia

• Ko te nuinga o ngā pūkaha hiko e mahi ana i roto i:
  20–60 hēkona (tere paerewa)
  Ka roa pea te wā e whakamahia ai ngā pūkaha puhoi kia tae ki te 120 hēkona mō ngā takirere nui kia kore ai e pāngia e te hama wai.

③Tarere Porowhita Whakaoho Hau

• He tere ake i te hiko engari he puhoi ake i ngā takirere whakaweto/whakakā.
  Te whānuitanga whānui: 3–20 hēkona, kei runga i te puna hau me te rahi o te actuator.

He aha i roa ake ai te mahi a ngā takirere porowhita

• ①Me haere te kakau i tawhiti kia tika ai te whakahaere i te rere.

• ②Me huri te wira ringaringa kia maha ngā wā hei karo i ngā panonitanga ohorere o te pēhanga.

• ③Ko te hoahoa o te takirere he mea nui ki te whakahaere rere me te tika, kaua ki te tere o te kati.

• ④Mā te puhoi o te mahi ka āwhina i te whakaiti i te hama wai, inā koa i roto i ngā pūnaha moana me ngā pūnaha ahumahi.

Ngā Āhuatanga e Pā Ana ki te Wā Whakahaere

• ①Rahi o te takirere me te whakatauranga pēhanga

• ②Te pikinga o te miro o te kakau (ngā miro angiangi = te neke haere puhoi)

• ③Momo pūwhakaoho (ā-ringa, hiko, hau, waipēhi)

• ④Pēhanga pūnaha

• ⑤Te waku, te pakaru rānei i roto i te takirere

• ⑥Ngā tautuhinga taipana, tere rānei i runga i ngā kaiwhakaoho

Mō ngā mahi moana, ka whakamahia te kati puhoi ake hei tiaki i ngā pūnaha wai moana, ngā raina taumaha, me ngā pūnaha whakamatao mai i ngā puhaketanga pēhanga ohorere.
