Ukwakhiwa kohlelo lwamanzi ezimboni kuhlukaniswa kusuka kuUkufakwa kwamapayipi wensimbinjengokuxhuma. Kuzicelo ezahlukahlukene ezinjengemvelo ephezulu yokucindezela, izimo zokusebenza ezedlulele noma izinto zokuhamba zegesi eziyingozi, isibalo esincane sokufakelwa okufakwayo singabonakala yonke indawo. Ukusebenza kwabo okuhle kakhulu ekumelaneni kwengcindezi, ukumelana nokuvinjwa nokubekwa uphawu kusiza uhlelo lwamanzi lusebenza ngokuphepha ngokuphepha nangenhle, okwenza bathembeke futhi basetshenziswe ngabantu abaningi.
Ukwakha uhlelo oluphephile lwamanzi, isisekelo ukukhetha umucu ofanele. Uma ufuna ukukhetha umucu ofanele, udinga ukukhomba kuqala.
Izinhlobo ezijwayelekile ze-Hikelok
Kunezinhlobo ezimbili zemicu ezisetshenziswa kakhulu nge-hikelok, eyodwa ingumucu wokuxhuma, ohlukaniswe ngentambo yentambo ye-m kanye ne-UN, enye yintambo yepayipi, ihlukaniswe intambo ye-NPT kanye nentambo ye-BSPT. Leli phepha lithatha ikakhulukaziintambo yepayipinjengesibonelo.
Izinhlobo zemicu yepayipi
(1) intambo ye-nPT(I-American National Standard Thread Thread), Isebenzisa i-ASME B1 20.1 Okujwayelekile, i-Angle yephrofayili i-Angle ingu-60 °, izinyo phezulu naphansi zisesimweni sendiza, kanti i-taper yentambo ye-conical ingu-1: 16, okuvame ukubizwa ngokuthi intambo ye-tap .
(2) Intambo ye-BSPP, ehambelana nentambo ye-G (i-British Standard Parallel Pipe), isebenzisa i-ISO 228-1 ejwayelekile, i-Angle yephrofayili ye-Angle ingu-55 °, izinyo eliphakeme futhi phansi ziyintambo ye-cylindrical, okuyi ngokuvamile ibizwa ngentambo efanayo.
(3) Intambo ye-BSPT, ehambelana nentambo ye-R (iBritish General Seaning Pine Thread), isebenzisa i-ISO 7-1 ejwayelekile, i-angle yephrofayili ye-ISO, i-Angle yephrofayili ingu-55 °, i-Toot top ne-TAPS TO PAIRC, bese i-taper yentambo ye-conical ingu-1: 16. Ngokuvamile owaziwa ngokuthi intambo ye-taper.
Ungakuqinisekisa kanjani ukucaciswa kwemicu emithathu yamapayipi
Kusuka kumininingwane engenhla, singazi ukuthi imicu yepayipi nayo ingahlukaniswa ngezigaba ezimbili: intambo ye-taper kanye nentambo ehambisanayo. Ngakho-ke, lapho uhlukanisa intambo, kufanele siqale sihlukanise ukuthi ngabe siyintambo ye-tap noma intambo efanayo.
Ukukhonjwa kokuqala
Isahlulelo sokuqala singenziwa ngokuya ngokuthi intambo inawo. Sebenzisa i-vernier caliper ukukala ububanzi phakathi kwamathiphu amazinyo entanjeni yokuqala, yesine neyedlule ngokulandela isikhundla esikhonjiswe esithombeni esingezansi. Uma ububanzi bukhuphuka kancane kancane noma buncipha, kukhombisa ukuthi intambo ine-taper, okuyintambo ye-BSPT noma intambo ye-NPT kwintambo ye-taper. Uma wonke amadayimitha efana, kukhombisa ukuthi intambo ayinayo i-taper futhi iyintambo ye-BSPP ye-parallel.
Ukuqinisekiswa okwengeziwe
Kunentambo eyodwa ye-BSPP yentambo ehambisanayo, ngakho-ke kuyadingeka ukuhlukanisa ukuhlukanisa noma ngabe kuyintambo ye-BST noma i-NPT entanjeni e-conical.
Izinyo lephrofayili angle angle isilinganiso: Yahlulelwa ngokusho kwe-angle yephrofayili yezinyo, intambo ye-BSTP nge-angle yephrofayili yezinyo engu-55 ° kanye nentambo ye-NPT nge-angle yephrofayili yezinyo engu-60 °.
Intambo ye-BSTPT NPT
Bheka ukwakheka kwezinyo: Gweba ngokwesimo sezinyo phezulu nezinyo ezansi zamazinyo. Intambo ye-BST inge-top round top kanye nxazonke, futhi intambo ye-NPT isesifundeni esiphezulu kanye nefulethi phansi.
Intambo ye-BSTPT NPT
Isahlulelo sokugcina
La mathuluzi amabili alandelayo ayadingeka ukuze aqinisekise ngokunembile uhlobo lwentambo.
Indlela 1: Sebenzisa i-Thread Gauge bese ukhetha igeji ehambisanayo yentambo yokuqinisekisa kokugcina. Intambo elinganisiwe iklwebheke ngokuphelele ngegeji yocingo. Uma kudluliswa imithetho yokuhlola i-Gave
Indlela 2: Sebenzisa igeji yezinyo bese ukhetha igeji yezinyo ehambisanayo ukuze uqhathanise kuze kube yilapho igeji yezinyo ifanela kahle ngentambo elilinganisiwe, khona-ke imininingwane yentambo ingukucaciswa kwangempela kwentambo elilinganisiwe.
Ngaphezu kwezindlela ezingenhla, singabheka namazinga wentambo ehambisanayo yemicu emithathu ngemuva kokulinganisa ububanzi be-vernier caliper kanye nokwahlulela intambo ye-vernier kanye nentambo ehambisanayo Njengomugqa olinganisiwe osezingeni lentambo ngokuqinisekiswa okwengeziwe, kepha isahlulelo sokugcina sisadinga usizo lwentambo yentambo ne-bauge yezinyo.
Lapho uthenga ama-hikelok Pipe Fittings, kunconywa ukuyifaka nokuyisebenzisa kanye nama-hikelok control valves. Ungakhethai-valve yenaliti, I-Ball valve, I-valve yokusiza, I-Metering valve, Bheka i-valve, Ama-Valve Manifolds, uhlelo lokusampula, njll., Ukuze wenze ukuxhumana kohlelo lwamanzi kuphephile futhi kusebenze kahle.
Ngemininingwane eminingi yoku-oda, sicela ubheke ekukhetheniamakhathalogiphezu kwa-Iwebhusayithi esemthethweni yeHikelok. Uma unemibuzo yokukhetha, sicela uthinte abasebenzi abasebenza ngokuthengisa abasebenza ngehora lama-24.
