I tēnei rā, ka whakaatu atu a Jinbin ki a koutou i tētahi takirere pūrerehua hiko whānui. He hoahoa karo tēnei takirere pūrerehua, ā, he taputapu hiko me te wira-ā-ringa kei roto. Ko ngā hua kei roto i te pikitia kongā takirere pūrerehuame ngā āhuatanga o te DN1000 me te DN1400 i hangaia e Jinbin Valves.

Ko ngā takirere pūrerehua whānui-rahi me te taha whakamuri (e pā ana ki te whānui ingoa DN≥500) he takirere motuhake e tāpiri ana i ngā paipa taha whakamuri me ngā takirere whakahaere iti ki te tinana takirere o ngā takirere pūrerehua tikanga. Ko tā rātou mahi matua he whakataurite i te rerekētanga pēhanga o te reo i mua me muri i te takirere mā roto i te taha whakamuri, hei whakaoti rapanga i te whakatuwheratanga, te kati me te whakahaere o ngā takirere whānui-rahi.

Ngā painga o te hoahoa i tētahi arai mō te takirere pūrerehua hiko nui-diameter

1. Whakaitihia te ātete ki te whakatuwheratanga me te kati, ā, tiakina te pūnaha taraiwa: Ina whakatuwheratia tika, ka katihia hoki ngā takirere whānui, he nui te rerekētanga pēhanga i waenga i te pāpāho o mua me muri, ka taea te whakaputa i te taipana nui, ka nui rawa te taumaha me te kino ki te taputapu taraiwa hiko/hau. Ka taea te whakatuwhera i te takirere karo i mua kia taea ai te rere mārire o te reo kia taurite ai te rerekētanga pēhanga, ka whakaiti i te taipana whakatuwheratanga me te kati o te takirere matua neke atu i te 60%, ā, ka roa ake te ora o te pūnaha taraiwa.

2. Whakaitihia te pakaru o ngā hiri: Ina nui rawa te rerekētanga o te pēhanga, ka pā te reo ki te mata hiri o te takirere matua, ka puta he rerekētanga me te pakaru o ngā hiri, ā, ka turuturu. I muri i te whakataurite i te pēhanga, ka taea te hono maeneene, te wehe rānei i te mata hiri o te takirere matua, ā, ka taea te whakaroa i te roa o te ora o ngā wāhanga hiri e 2 ki te 3 ngā wā.

3. Āraia te pānga o te hama wai: I roto i ngā paipa whānui, ka taea e te whakatuwheratanga me te kati ohorere o ngā takirere te hanga i te hama wai (te pikinga me te hekenga ohorere o te pēhanga), ka pakaru pea i roto i te paipa, ka kino rānei te taputapu. Ka āta whakahaere te takirere taha i te tere rere, ka taea te ārai i ngā pikinga o te pēhanga me te whakakore i te mōrearea o te hama wai.

4. Whakapai ake i te ngāwari o te tiaki: Ina hiahiatia te tirotiro me te whakatika i te takirere matua, kāore he take e kati ai te pūnaha katoa. Katia noa te takirere matua ka whakatuwhera i te takirere taha hei pupuri i te rere taketake o te reo me te whakaiti i ngā mate wā whakatā o te whakaputanga.

Teneitakirere pūrerehua flangede whakamahia pinepine ana i roto i ngā horopaki e whai ake nei:

1. Te tuku wai me te rerenga wai ā-tāone: Me whakarerekē tonu te tere rere o ngā paipa kawe wai matua o ngā whare wai me ngā paipa paru nui o te tāone (DN500-DN2000). Mā te arai wai ka ārai i te pānga ki te whatunga paipa i te wā e tuwhera ana, e kati ana hoki.

2. Ahumahi matū hinu: Mō ngā paipa kawe hinu mata me te hinu kua whakapaia (i raro i ngā āhuatanga pēhanga teitei), me whai paipa taha ngā takirere pūrerehua whānui hei ārai i te pānga waenga ki ngā wāhanga hiri me te whakarite i te haumaru o te kawe.

3. Ngā tipu hiko wera/karihi: Mā te pūnaha wai e rere ana (he whānui te diameter o ngā paipa wai whakamatao), ka taea e te taha taha te whakahaere maeneene i te rere o te wai me te ārai i te kino o te hama wai ki ngā taputapu matua pēnei i ngā whakapūmau hiko.

4. Ngā kaupapa tiaki wai: Ko ngā awaawa nui e whakawhiti ana i te wai me ngā paipa whakamakuku matua e hiahia ana ki ngā takirere whānui hei whakahaere i te nui o te wai. Mā te arai taha ka taea te whakatuwhera me te kati maeneene, me te tiaki hoki i te hanganga o te awaawa.

He maha ngā tau o te wheako o Jinbin Valve (Ngā Kaihanga Valve Pūrerehua) ki te hanga i ngā valve pūrerehua whānui-rahi, ā, ka hoahoa motuhake, ka whakarite hoki i ngā otinga tono valve mō ngā kiritaki.
