API Konumohe Takirua/Takitoru Āputa/Wafer/Flange Pūrerehua Takirua Ahumahi Petrochemical Haina wheketere
He aha te mea e kiia ana ko te Triple Offset Butterfly Valve Lug?
Te pūwero takirere pūrerehua āwhati-toru, e mōhiotia ana hoki kotakirere pūrerehua āwhati-toru,he momo takirere pūrerehua mahi teitei, i hangaia mō ngā āhuatanga mahi o te pēhanga teitei, te pāmahana teitei, me ngā auau teitei o te whakatuwhera me te kati.
He pono te kounga o te takirere pūrerehua kua whakakikoruatia ki te rapa porowhita, me te hoahoa me te hangarau hanga kua pakeke, ā, he pai te utu. Engari mō ngā tono nui pēnei i te pāmahana teitei, i ngā auau whakatuwheratanga me te katinga teitei rānei, kāore e whakaaetia kia whakamahia ngā takirere pūrerehua nohoanga ngohengohe. Nō reira, ka whakamahia ngā takirere pūrerehua hiri mārō, te nohoanga whakarewa, te nohoanga uku rānei, i hangaia mō te pāmahana teitei, te pēhanga teitei, ngā auau tuwhera-kati teitei rānei, engari he āwangawanga nui tonu te mahi hiri o te takirere pūrerehua hiri mārō tuku iho.
te kore turuturu o tā mātoutakirere pūrerehua rerekē toruKa whakatinanahia mā te mowhiti hiri kowiri tira hiato e mau ana ki te kōpae. Ko te hoahoa o te hurihanga matau-koki me te kore waku ka whakatinanahia e te mātāpono motuhake o te toru-āhua. Ka whakakorea te waku i waenga i te nohoanga me te mowhiti hiri i te hurihanga 90º. Ko te taipana iti ake te tikanga ka taea e tātou te tīmata i te takirere me te actuator iti ake, hei penapena i te nui o te utu me te wāhi.
Te hoahoa o te taura pūrerehua āwhati toru
- Ko te whakarerekētanga tuatahi ko te pupuri i te rakau takirere ki muri i te rakau kōpae kia taea ai e te hiri te kati katoa i te nohoanga takirere.
- Ko te tuarua o ngā rerekētanga ko te wehe i te raina pokapū o te rakau takirere mai i te paipa me te raina pokapū takirere hei karo i te pokanoa mai i te whakatuwheratanga me te katinga o te takirere.
- Ko te tuatoru o ngā rerekētanga ko te peka ke o te tuaka o te koeko nohoanga mai i te rārangi pokapū o te rakau takirere, e whakakore ana i te waku i te wā e kati ana, e whakatuwhera ana hoki, ā, e tutuki ai he hiri pēhanga ōrite huri noa i te nohoanga katoa.
Ko te whakataki o runga ake nei ko tetakirere pūrerehua rerekē toruHe momo takirere pūrerehua mahi-teitei e whakamahia ana i tēnei wā i roto i ngā mara maha.
Ngā āhuatanga matua o te pūwero pūrerehua āwhati toru
- Mā te mowhiti hiri whakarewa hiato ka tino tohatoha te kaha nohoanga huri noa i te porowhita nohoanga i hangaia e te mīhini tika.
- Mā te anga ira o te flange ka whakarite kia papatahi te nati pūtu me te mīhini horoi, ka nui ake te pono me te haumaru o ngā hononga.
- Ngā mowhiti hiri takirua maha-paparanga me te hiri karāhe ka taea te whakakapi ngāwari.
- He rākau kotahi-wahi tino whakakaha, kua hangaia hei whakawhiti/pupuri i te taipana me te whai hua.
- Ka āraihia e ngā parenga whīra graphite te urunga o te paru, kia mau tonu ai te oma o te taipana me te mahi tonu o te takirere.
- Mā te repe tākai e rua ngā wahi me te tākai karāhe ka whakaiti i te mōrearea tukunga o waho.
- Hononga matua-ki-kōpae kua mau mō te pumau o te kakau.
- Ka taea te whakakapi i ngā gaskets, te hiri me ngā mowhiti tākai mō ngā porowhita, kāore he taputapu motuhake.
- Ka tu atu ngā peera taumaha i ngā kawenga pēhanga teitei me te pakaru.
- Ko te whakahaere i ngā mōrearea o te tangohanga o ngā rakau ā-roto, ā-waho hoki, e tutuki ana i ngā paerewa o te ao.
