I te nuinga o te wā, ko te diameter o te nohoanga he rite ki te rahi o te kākano takirere. He whānui rawa te rauemi nohoanga takirere pūrerehua, ko ngā rauemi e whakamahia whānuitia ana ko te EPDM hiri ngohengohe, NBR, PTFE, me te rauemi hiri karāti mārō whakarewa. Ka whai ake ka whakaatuhia e mātou tētahi i muri i tētahi...
Ko te takirere tirotiro e pā ana ki ngā wāhanga whakatuwhera me te kati mō te takirere porowhita, ā, e whakawhirinaki ana ki tō rātou ake taumaha me te pēhanga pāpāho hei whakaputa mahi hei aukati i te rere whakamuri waenga o te takirere. Ko te takirere tirotiro he takirere aunoa, e mōhiotia ana ko te takirere tirotiro, te takirere kotahi-ara, te takirere kore-hoki, te takirere wehe rānei.
Ngā takirere tirotiro angiangie mōhiotia ana hoki ko ngā takirere rere whakamuri, ngā takirere aukati, me ngā takirere pēhanga whakamuri. Ka whakatuwheratia, ka kati aunoatia ēnei momo takirere e te kaha e puta mai ana i te rere o te reo i roto i te paipa, nō tētahi momo takirere aunoa.
Nā te iti o te rahi me te ngāwari o te hanganga, kua noho ko te takirere pūrerehua tētahi o ngā takirere e whakamahia whānuitia ana i roto i te umanga, ā, he maha ake ngā whakamahinga mō te hiko wai, te whakamakuku, te tuku wai me te rerenga wai o ngā whare, te hangarau ā-tāone me ētahi atu pūnaha paipa, e whakamahia ana hei tapahi, hei whakahaere rānei i te rere o te rere o ngā pāpāho e rere ana. Kātahi ka whakamahia te takirere pūrerehua hei whakaoti i ngā raruraru e hiahia ana kia arohia, kia whakatauhia hoki, ā, ka mārama tātou i tēnei rā.
Ko ngā takirere kuaha hiri ngohengohe me ngā takirere kuaha hiri mārō he taputapu e whakamahia whānuitia ana hei whakahaere me te aukati i te rere, he pai te mahi hiri a ngā mea e rua, he whānui te whakamahinga, ā, ko tētahi o ngā hua e hokona nuitia ana e ngā kaihoko. Tērā pea ka hiahia ētahi o ngā tauhou ki te hoko, he rite tonu ki te takirere kuaha, he aha te rerekētanga motuhake i waenganui i a rāua.
Ko te paerewa AWWA te tuhinga whakaae tuatahi a te American Water Works Association i te tau 1908. I ēnei rā, neke atu i te 190 ngā Paerewa AWWA. Mai i te pūtake ki te rokiroki, mai i te maimoatanga ki te tohatoha, ka hipokina e ngā Paerewa AWWA ngā hua me ngā tukanga e pā ana ki ngā wāhanga katoa o te maimoatanga me te tuku wai. Ko te AWWA C504 tētahi o ngā tohu noa, he momo takirere pūrerehua nohoanga ururua.
Ko ngā takirere pūrerehua rahi-rahi e pā ana ki ngā takirere pūrerehua he nui ake te diameter i te DN500, e honoa ana e ngā flanges, ngā wafers. E rua ngā momo takirere pūrerehua whānui-diameter: ko te takirere pūrerehua porowhita me ngā takirere pūrerehua rerekē.
Ko ngā āhuatanga rerekē e toru o te Takirere Pūrerehua Eccentric Toru e pā ana ki:
Ko te tuatahi o ngā āhuatanga rerekē: kei muri i te pereti takirere te rakau takirere, e āhei ai te hirimowhiti kia karapoti tata i te nohoanga katoa e pa ana.
Ko te tuarua o ngā rerekētanga: kua wehea te poupou ki te taha mai i te hēnetier te rārangi o te tinana takirere, e ārai ana i te pokanoa ki te whakatuwheratanga me te katinga o te takirere.
Tuatoru o ngā āhuatanga rerekē: te nohoanga kua wehea mai i te rārangi pokapū o te rakau takirere, e whakakore ana i te waku i waenga i tekōpae me te nohoanga i te wā e kati ana, e whakatuwhera ana hoki.
Ko te ingoa o te takirere pūrerehua rerekē takirua i ahu mai i ōna hanganga rerekē e rua. Nō reira, he aha te āhua o te hanganga rerekē takirua?
Ko te mea e kiia nei ko te takirua-ā-ira, ko te tuatahi o ngā ā-ira e pā ana ki te rakau takirere kei waho o te pokapū o te mata hiri, ko te tikanga kei muri te kakau i te mata o te pereti takirere. Nā tēnei āhua ā-ira ka waiho te mata pa o te pereti takirere me te nohoanga takirere hei mata hiri, e whakakore ana i ngā ngoikoretanga ā-roto e kitea ana i roto i ngā takirere pūrerehua porowhita, ā, ka whakakorea te tūponotanga o te turuturu o roto i te hononga o runga me raro i waenganui i te rakau takirere me te nohoanga takirere.
Ko te takirere pūrerehua, e kiia ana hoki ko te takirere taupoki, he hanganga māmā o te takirere whakatikatika, ka taea te whakamahi i roto i ngā paipa pēhanga iti hei aukati i te rere. Ka hurihuri i te kakau takirere hei whakatuwhera me te kati i te takirere.
E ai ki ngā momo hononga rerekē, ka taea te wehewehe ki te takirere pūrerehua wafer, te takirere pūrerehua lug, te takirere pūrerehua flange, te takirere pūrerehua stitched, te takirere pūrerehua miro tīwiri, te takirere pūrerehua rawhi, me ētahi atu.

E tutuki ana ā mātou takirere pūrerehua wafer ki ngā paerewa ā-ao o te takirere o ASTM, ANSI, ISO, BS, DIN, GOST, JIS, KS me ērā atu. Rahi DN40-DN1200, pēhanga ingoa: 0.1Mpa~2.5Mpa, pāmahana e tika ana: -30℃ ki te 200℃.
Ko te nuinga o tā mātou kaweake ki ngā whenua 22 pērā i te US, Russia, Canada, Spain me ētahi atu.
ngā rauemi, te maitai kore waikurangā takirere pūrerehuaKei te wātea ngā takirere pūrerehua kowiri tira i roto i ngā momo SS304, SS316, SS304L, SS316L, SS2205, SS2507, SS410, SS431, SS416, SS201. Mō te hanganga, kei te wātea ngā takirere pūrerehua kowiri tira i roto i ngā momo pokapū me ngā momo rerekē. Ko ngā takirere pūrerehua kowiri tira raina pokapū he mea hanga i te kowiri tira mō te tinana takirere, te pereti takirere, me te pou, me te EPDM, te NBR rānei mō te nohoanga takirere. He mea hanga ēnei mō te whakahaere rere me te whakahaere i ngā mea waikura, inā koa ngā waikawa kaha, pērā i te waikawa whanariki me te aqua regia.
