He kaihanga ngaio a Zhongfa Valve mō ngā wāhanga takirere pūrerehua me ngā takirere pūrerehua, i whakatūria i te tau 2006, e whakarato ana i ngā hua takirere me ngā wāhanga takirere pūrerehua ki neke atu i te 20 whenua o te ao, ā, i te wā e whai ake nei, ka whakarewahia e Zhongfa Valve he whakaaturanga taipitopito o ngā wāhanga takirere pūrerehua.
Ko ngā wāhanga o te takirere pūrerehua he mea hanga ki ngā wāhanga e whai ake nei, ko ngā ingoa o ngā wāhanga pūrerehua ko te tinana takirere, te kōpae takirere, te pou takirere, te nohoanga takirere, te mata hiri, me te kaiwhakahaere mahi. Nā, ka whakaatuhia e mātou ēnei wāhanga takirere pūrerehua takitahi.
# 1 Ngā wāhanga takirere pūrerehua--Te tinana takirere
Ka kōrerohia e mātou te tinana takirere e pā ana ki te hononga me ngā rauemi.
1. I te nuinga o te wā, e ai ki ngā tikanga hononga rerekē, he momo flange, he momo wafer, he momo lug ngā takirere pūrerehua, ā, kei te whakaatuhia ngā momo āhua tata ki te pikitia. Mō ia momo hononga, he rerekētanga ngawari e ai ki ngā pokepokea rerekē, pērā i te takirere pūrerehua wafer, kei a Zhongfa Valve ēnei pokepokea noa.
2. E ai ki te rauemi, ko ngā mea e tino kitea ana ko te tinana rino ngāwari, te tinana maitai waro, te tinana maitai kore waikura, te tinana parahi, me te tinana maitai tino takirua.
#2Ngā wāhanga o te takirere pūrerehua--Kōpae Takirere
He rerekē anō hoki te momo kōpae takirere, pērā i te kōpae pine, te kōpae kore pine, te kōpae rapa, te kōpae nairona, te kōpae whakakikoruatia hiko, me ētahi atu. I te nuinga o te wā, ka tīpakohia te kōpae takirere i runga i ngā āhuatanga mahi me te reo.
Mō te kōpae kore-pine, he pou mā roto, he pou haurua takirua. Mā te kōpae kore-pine ka whakaiti i te tūponotanga o te turuturu. Mō te kōpae he pine, tera pea kua tawhito, kua waikura rānei te pine i muri i te wā roa, ka puta te kōhao turuturu mai i te pine ki te kōpae. E hiahia ana mātou ki te whiriwhiri i tētahi kōpae kore-pine mō tā mātou kiritaki.
# 3 Ngā wāhanga takirere pūrerehua--Taiwa Miro
Ko te miro takirere pūrerehua, e kiia ana hoki ko te kakau, e whakamahia ana mō te tuku, e hono ana ki te actuator, ki te kakau rānei, ko te mea e whai ake nei ka akiaki tika i te hurihanga o te pereti takirere, kia tutuki ai te mahi pana takirere pūrerehua, te mahi whakatikatika rānei.
1. Mai i te rauemi: Ko te rauemi porowhita he mea hanga i te kowiri tira me te maitai waro, ko tōna waehere ko: kowiri tira (2cr13, 304, 316, 316L), maitai waro (35, 45, Q235).
2. Mai i te momo: te takirere pūrerehua mā roto i te pou (mauī) me te pou haurua takirua o te takirere pūrerehua (matau).
a: Mō te utu: he nui ake te utu o te poro-haurua takirua i te poro-mā roto.
b: Mō te whakamahinga: ka taea e te haurua-poro rua te mahi i te neke atu i te DN300, ā, ka taea e te poro mā roto te mahi i te DN800.
c: Te maha o ngā hononga: ka taea te whakamahi i ngā hononga mā roto i ngā pou i runga i ngā takirere pūrerehua kua pinea me te tere para iti. Ko ngā takirere pūrerehua haurua-pou takirua anake ka taea te whakamahi, ā, he nui te tere para.
d: Huihuinga: ko te tikanga taketake o te hoahoa ko te whakamahi i te poupou mā roto i te kore he pine, he hoahoa māmā, he tukatuka poupou, he uaua te hanga i te haurua-poupou rua, e wehea ana ki te poupou o runga, me te poupou o raro.
# 4 Ngā wāhanga takirere pūrerehua--Nohoanga Takirere
Ka taea te wehewehe i te nohoanga rapa o te takirere pūrerehua hiri ngohengohe ki te nohoanga rapa tuara-mārō me te nohoanga rapa tuara-ngāwari, ā, ko te nohoanga o te takirere pūrerehua hiri pakeke he hiri tika me te hiri maha-taumata te nuinga.
Ko te rerekētanga i waenga i te nohoanga rapa tuara-mārō me te nohoanga rapa tuara-ngohengohe o te takirere pūrerehua: ka pēhia te nohoanga tuara-mārō ki te tinana takirere me ngā mea whakakoi, kāore e taea te whakakapi i a ia anō, ā, me whai flange motuhake mō te takirere pūrerehua; ko te nohoanga tuara-ngohengohe he mea hanga e te tauira, ka taea te whakakapi i a ia anō, ā, ka taea te whakamahi me te flange kāore i te motuhake mō te takirere pūrerehua.
Mō te roa o te ora o te nohoanga rapa, he roa ake te ora o te nohoanga ngohengohe o muri i tērā o te nohoanga pakeke, he hanganga whānui nui. Ka roa te wā e whakamahia ana te takirere, ā, ka pakaru te pito o te kakau o te nohoanga takirere. I muri i te turuturu o te wai o te nohoanga pakeke o muri, ka puta te turuturu o te pito o te kakau o te nohoanga takirere ki waho o te tinana takirere. Engari kāore te tuara ngohengohe e puta mai i tēnei āhuatanga.
# 5 Ngā wāhanga takirere pūrerehua--Mata hiri
he hiri ngohengohe, he hiri mārō hoki,Te kōwhiringa o ngā rauemi hiri ngohengohe:
1, Rapa (tae atu ki te rapa butadiene, te rapa EPDM, me ētahi atu), e whakamahia ana i roto i ngā paipa pēhanga iti i runga i te hinu me te wai.
2, Kirihou (PTFE, nairona, me ētahi atu), he pai ake mō ngā mea waikura i roto i te paipa.
Aratau whakahaere: kakau, turbo, hiko, hau, waipēhi
Te kōwhiringa o ngā rauemi hiri mārō:
1, koranu parahi (mō ngā takirere pēhanga iti)
2, Kowiri tira Chrome (mō ngā takirere pēhanga teitei me te pēhanga waenga noa)
3、Konumohe Stellite (mō ngā takirere pāmahana teitei me te pēhanga teitei me ngā takirere waikura kaha)
4、Ngā koranu e hangai ana ki te nikara (mō ngā mea waikura)
# 6 Ngā wāhanga takirere pūrerehua--Whakahohenga Mahi
Ko ngā takirere pūrerehua e whakahaerehia ana i roto i ngā mea e whai ake nei, te Rīwhi Ringa, te Taputapu Noke, te Pūwhakaoho Hau.
He mea hanga ngā rīpene ringaringa ki te mea pakari, kua rongoatia ki te matū, ā, kua pania ki te paura. He kakau me te rīpene honohono te nuinga o te wā kei roto i te rīpene ringaringa, he mea e tika ana mō te DN40-DN250.
He pai te taputapu noke mō ngā takirere pūrerehua nunui. Ko te pouaka noke te tikanga e whakamahia ana mō ngā rahi nui atu i te DN250, kei reira tonu ngā pouaka tāpine e rua-wāhanga me te toru-wāhanga.
E rua ngā momo o ngā kaiwhakaoho hau, arā, ngā kaiwhakaoho hau mahi-kotahi me ngā kaiwhakaoho hau mahi-rua.
Ka taea te wehewehe i ngā pūkaha hiko ki ngā momo hurihanga maha-huringa me ngā momo hurihanga-wāhanga. Ko te momo hurihanga maha-huringa ka huri i te 360° neke atu hei whakatuwhera me te kati i te takirere, ko te momo hurihanga-wāhanga ia ka huri i te 90° hei whakatuwhera me te kati katoa i te takirere.
Muri iho, me titiro tātou me pēhea te tāuta ngātahi i ngā wāhanga o te takirere pūrerehua.
