1. He aha te PTFE Fully Lined Butterfly Valve?
He whānuitia te whakamahinga o ngā takirere pūrerehua PTFE (polytetrafluoroethylene) kua whakakīia katoatia ki roto i ngā pūnaha paipa mō ngā mea tino waikura (pērā i ngā waikawa kaha, ngā turanga kaha, me ngā whakarewa waro) nā te mea kua whakakīia katoatia te tinana takirere me te kōpae ki te PTFE, e whakarato ana i te ātete waikura me te mahi hiri pai rawa atu. E rua ngā momo o te hanganga tinana takirere: te tinana rua-wahi (tinana wehea) me te tinana kotahi-wahi. Ko tehanganga wāhanga-ruakoinei te hoahoa matua mō ngā takirere pūrerehua PTFE kua whakarārangihia katoatia, ko te hoahoa kotahi-wahi ia he iti ake te rongonui, nā ngā herenga o te tukanga whakarārangi.
2. Ngā Āhuatanga Rite
Rahi:DN50-DN600. He rerekē ki ngā takirere pūrerehua tuku iho me ngā nohoanga EPDM, ko te rahi iti rawa mō ngā nohoanga PTFE ko DN50.
Pēhanga:Nā te mea he mea here ki te rauemi PTFE, inā koa te kōpae kua whakakikoruatia ki te PTFE, he pai mō te pēhanga mōrahi o te PN10 (me whai whakaritenga motuhake mō te PN16).
Te pāmahana:Ko te pāmahana whakahaere he -10 ki te 180 nekehanga Celsius. (Ko te RPTFE he -20 ki te 200 nekehanga Celsius i te nuinga o te wā)
3. Ngā Rerekētanga Matua me te Whakataurite
3.1 Ngā Āhuatanga Hanganga
Ngā wahi e ruaTinana(Tinana Wehewehe)Ko te tinana takirere he mea hanga ki ngā haurua e rua (e rua rānei ngā wahi) kua huihuia, ā, kua honoa mā roto i ngā pūtu. Ka hangaia te arai ki ia haurua motuhake i mua i te huihuinga.
Tinana Kotahi-Wāhanga (Tinana Katoa):Ka whakarewaina, ka mīhinihia rānei te tinana takirere hei wāhanga kotahi, ā, me werohanga te arai, me whakamahi rānei i tētahi tukanga motuhake hei whakakī katoa.
3.2 Tukanga Hanga
Tinana takirere pūrerehua wehea:Ko te tinana takirere he mea hanga mai i ngā wāhanga o runga me raro e honoa ana e ngā pūtu. Ko te arai PTFE (tae atu ki ngā mowhiti silicone) ka hangaia motuhaketia i mua i te huihuinga. Nō reira, he māmā ake te tukanga arai mō te tinana e rua ngā wāhanga, ā, kāore e hiahiatia he pokepokea motuhake, he taputapu rānei mō te huihuinga.
Katoatinana takirere pūrerehuaKa whakarewaina, ka mīhinihia rānei te tinana takirere hei wāhanga kotahi, kāore he mata hononga waenga. Ka honoa te arai PTFE ki te tinana takirere mā te whakahāngai whakauru, te whakahinuhinu rānei.
3.3 Te Mahi Hiri
E rua ngā wāhanga (Tina Wehewehe):Kāore he turuturu ā-rua (kāore he mirumiru), engari me whai hoahoa hiri pai te mata hononga (pērā i ngā mowhiti-O, i ngā gasket rānei).
Kotahi-wahi (tinana katoa)Kāore he mata hononga, he iti ake ngā pūwāhi turuturu pea, ā, he nui ake te pono o te hiri.
3.4 Ngā Rahi e Pā Ana
Ngā wāhanga e rua (Tinana Wehewehe):E wātea ana i te nuinga o te wā i waenga i te DN50~DN600, ā, he ngāwari noa iho te whakatutuki i ngā rahi nunui ake.
Kotahi-wahi (Tino Monoblock)Ko te nuinga he iti noa ngā diameter; he uaua te hanga i ngā rahi nui ake.
3.5 Ngāwari o te Tiaki
Tinana takirere pūrerehua e rua ngā wahi:Tino pai: He māmā te wetewete, kāore he taputapu motuhake e hiahiatia ana, ā, ka taea te whakakapi takitahi i ngā haurua arai, i te kōpae pūrerehua rānei, kia māmā ai te tiaki.
Tinana takirere pūrerehua kotahi-wahi:Kino: He uaua ki te whakatika ā-rohe ina pakaru te arai; me whakakapi te tinana takirere katoa i te nuinga o te wā.
3.6 Te utu
Ngā wāhanga e rua:Kei runga ake, he mowhiti silicone kei roto i te nohoanga PTFE hei whakanui ake i te ngāwari me te mahi hiri.
Kotahi-wahiHe iti iho, ahakoa he uaua te tukanga whakapuru (he ngoikore te ngāwari o te PTFE, ā, he uaua ki te werohia kia ōrite ki roto i te tinana takirere kotahi-wahi), ā, he uaua te hanga, he hangarau pakari tā tā mātou kamupene, ā, he iti ake ngā utu.
3.7 Ngā horopaki tono
Ngā wahi e rua Ko te kōwhiringa matua, e tino kitea ana i roto i ngā paipa matū, rongoā, wai para, me ngā paipa waikura.
Kotahi-wahiWhakamahia mō ngā tono motuhake e tino hiahiatia ana (pērā i ngā whakaritenga hiri tino teitei me te kore e hiahiatia he tiaki), engari he iti ake te whakamahinga i roto i ngā takirere pūrerehua PTFE kua whakakīia katoatia.
