Ko te hanganga o te punaha wai ahumahi kaore e taea te wehe mai i tetaputapu paipa taputapuhei hononga.I roto i nga momo tono penei i te taiao pehanga nui, nga ahuatanga mahi tino kino, te kawe hau-wai kino ranei, ka kitea te ahua iti o nga taputapu miro ki nga waahi katoa.Ko ta raatau mahi pai i roto i te aukati pehanga, te aukati wiri me te hiri ka awhina i te punaha wai kia pai ake te whakahaere me te pumau, ka whakawhirinakihia, ka whakamahia e te tini o nga tangata.
Hei hanga i tetahi punaha wai haumaru, ko te kaupapa ko te kowhiri i te miro tika.Ki te hiahia koe ki te kowhiri i te miro tika, me tautuhi koe i te tuatahi.
Nga momo miro noa o Hikelok
E rua nga momo miro e whakamahia nuitia ana e Hikelok, ko tetahi he miro hono, ka wehea ki te miro M me te miro UN, ko tetahi he miro paipa, ka wehea ki te miro NPT, miro BSPP me te miro BSPT.Ko tenei pepa te nuingamiro paipahei tauira.
Nga momo miro paipa
(1) NPT miro(American National Standard Pipe Thread), ma te whakamahi i te paerewa ASME B1 20.1, ko te koki tohu niho he 60 °, ko te niho runga me raro kei te ahua rererangi, ko te taper o te miro koeko he 1 ∶ 16, e kiia nei ko te miro taper. .
(2) miro BSPP, e rite ana ki te miro G (British Standard Parallel Pipe), e whakamahi ana i te paerewa ISO 228-1, ko te koki tohu niho he 55 °, ko te niho o runga me raro he pewa te ahua, ko te miro o roto me waho he miro paipa porotakaroa, he ka kiia ko te miro whakarara.
(3) miro BSPT, e rite ana ki te miro R (te miro paipa hiri a Ingarangi), ka whakamahi i te paerewa ISO 7-1, ko te koki tohu niho he 55 °, he porohita porohita te niho o runga me raro, ko te taper o te miro koeko he 1∶16.E mohiotia ana ko te miro taper.
Me pehea te whakau i nga korero mo nga miro paipa e toru
Mai i nga korero o runga ake nei, ka mohio tatou ka taea ano te whakarōpūtia nga miro paipa ki nga waahanga e rua: miro taper me te miro whakarara.Na reira, i te wa e wehewehe ana i te miro, me tohu he miro taper, he miro whakarara ranei.
Te tautuhi tuatahi
Ka taea te whakatau tuatahi i runga i te mea he taper te miro.Whakamahia he anga vernier hei ine i te diameter i waenga i nga pito niho i te miro tuatahi, tuawha me te miro whakamutunga kia rite ki te tuunga e whakaatuhia ana i te ahua i raro nei.Mena ka piki haere, ka heke iho ranei te diameter, e tohu ana he taper te miro, he miro BSPT, he miro NPT ranei kei roto i te miro taper.Mena he rite nga diameters katoa, e tohu ana kaore he tapere o te miro, he miro whakarara BSPP.
Te whakapumautanga ano
Kotahi noa te miro BSPP mo te miro whakarara, no reira he mea tika ki te wehewehe mena he miro BSPT he miro NPT ranei kei te miro koeko.
Te ine ine koki tohu niho: ka whakatauhia i runga i te koki tohu niho, ko te miro BSPT me te koki tohu niho 55 ° me te miro NPT me te koki tohu niho 60 °.
BSPT Miro NPT Miro
Tirohia te ahua o te niho: whakawa i runga i te ahua o te niho o runga me te niho o raro.Ko te miro BSPT kei te porowhita o runga me te porowhita o raro, ko te miro NPT kei runga papatahi me raro papatahi.
BSPT Miro NPT Miro
Whakawa Whakamutunga
Ko nga taputapu e rua e whai ake nei e hiahiatia ana hei whakauru tika i te momo miro.
Tikanga 1: whakamahia te ine miro ka kowhiri i te ine miro e rite ana mo te whakapumautanga whakamutunga.Ko te miro ine kua tino wirihia ki te mehua miro.Mena ka paahitia nga ture tirotiro ine miro e tika ana, ko te tohu miro ko te tohu tuturu o te miro ine.
Tikanga 2: whakamahia te ine niho ka kowhiri i te ine niho e rite ana hei whakatairite tae noa ki te pai o te mehua niho ki te miro ine, katahi ko te tohu miro ko te tino tohu o te miro ine.
I tua atu i nga tikanga o runga ake nei, ka taea ano e tatou te tirotiro i nga paerewa miro e tika ana mo nga miro e toru i muri i te ine i te diameter o te karauna miro me te caliper vernier me te whakatau i te miro taper me te miro whakarara, ka kitea te tohu miro me te diameter o te karauna miro ano. rite te miro ine i roto i te paerewa miro mo te whakau ake, engari ko te whakawa whakamutunga me awhina tonu te awhina o te mehua miro me te mehua niho.
I te wa e hoko ana i nga taputapu paipa Hikelok, e taunaki ana kia whakauruhia me te whakamahi tahi me nga riu mana Hikelok.Ka taea e koe te whiriwhiritaki ngira, paoro poroporo, takirere tanga orite, inenga takirere, taki takirere, nga manifolds valve, pūnaha whakatauira, me etahi atu, kia pai ake ai te pai o te hononga o te punaha wai.
