Ukwakhiwa kwenkqubo yolwelo lwamashishini ayinakwahlulwa kwiizixhobo zombhobho wesixhobonjengonxibelelwano. Kwizicelo ezahlukeneyo ezifana nemeko-bume yoxinzelelo oluphezulu, iimeko zokusebenza ezigqithisileyo okanye ukuthuthwa okuyingozi kwegesi-ulwelo, isibalo esincinci sezinto ezifakwe kwimisonto sinokubonwa kuyo yonke indawo. Ukusebenza kwabo okugqwesileyo kukumelana noxinzelelo, ukumelana nokungcangcazela kunye nokutywinwa kunceda inkqubo yolwelo isebenze ngokukhuselekileyo nangokuzinzileyo, ibenze bathembeke kwaye basetyenziswe ngabantu abaninzi.
Ukwakha inkqubo yolwelo ekhuselekileyo, isiseko kukukhetha umsonto ochanekileyo. Ukuba ufuna ukukhetha umsonto ochanekileyo, kufuneka uwuchonge kuqala.
Iintlobo zemisonto eqhelekileyo yeHikelok
Kukho iintlobo ezimbini zeentambo eziqhelekileyo ezisetyenziswa nguHikelok, enye idibanisa intambo, eyahlulahlulwe ibe yi-M intambo kunye nentambo ye-UN, kwaye enye intambo yombhobho, eyahlulahlulwe kwintambo ye-NPT, intambo ye-BSPP kunye nentambo ye-BSPT. Eli phepha ikakhulu lithathaumsonto wombhobhonjengomzekelo.
Iindidi zemisonto yombhobho
(1) Umsonto weNPT(I-American National Standard Pipe Thread), usebenzisa i-ASME B1 20.1 esemgangathweni, i-angle yeprofayili yezinyo yi-60 °, umphezulu wezinyo kunye nomzantsi ukwimeko yendiza, kunye ne-taper yentambo ye-conical yi-1 ∶ 16, ebizwa ngokuba yi-taper thread. .
(2) intambo ye-BSPP, ehambelana ne-G intambo (i-British Standard Parallel Pipe), isebenzisa umgangatho we-ISO 228-1, i-angle yeprofayili yezinyo yi-55 °, umphezulu wezinyo kunye nezantsi zenziwe nge-arc, kwaye intambo yangaphakathi nangaphandle yintambo yombhobho wecylindrical, ngokubanzi ebizwa ngokuba yi-parallel thread.
(3) intambo ye-BSPT, ehambelana nentambo ye-R (intambo yombhobho wokutywina jikelele waseBritani), isebenzisa umgangatho we-ISO 7-1, i-angle yeprofayili yezinyo yi-55 °, umphezulu wezinyo kunye nomzantsi yi-arc ejikelezayo, kunye ne-taper ye-conical thread yi-1∶16. Ngokuqhelekileyo eyaziwa ngokuba yi-taper thread.
Indlela yokuqinisekisa iinkcukacha zemicu emithathu yombhobho
Ukususela kolu lwazi lungentla, sinokwazi ukuba imicu yombhobho nayo ingahlelwa ibe ngamacandelo amabini: intambo ye-taper kunye nentambo ehambelanayo. Ngoko ke, xa sihlula intambo, kufuneka siqale sahlule ukuba ngaba yimisonto e-taper okanye i-parallel thread.
Ukuchongwa kwangaphambili
Isigwebo sokuqala singenziwa ngokuhambelana nokuba intambo ine-taper. Sebenzisa i-vernier caliper ukulinganisa ububanzi phakathi kweengcebiso zamazinyo kwintambo yokuqala, yesine kunye neyokugqibela epheleleyo ngokwendawo eboniswe kumfanekiso ongezantsi. Ukuba i-diameter inyuka ngokuthe ngcembe okanye iyancipha, ibonisa ukuba intambo ine-taper, eyintambo ye-BSPT okanye intambo ye-NPT kwintambo ye-taper. Ukuba zonke iidiameters ziyafana, oko kubonisa ukuba intambo ayinayo i-taper kwaye i-parallel thread BSPP intambo.
Olunye uqinisekiso
Kukho intambo enye kuphela ye-BSPP yomsonto ohambelanayo, ngoko ke kuyimfuneko ukwahlula ngakumbi ukuba intambo ye-BSPT okanye intambo ye-NPT kumsonto weconical.
Umlinganiselo we-engile yezinyo: igwetywe ngokwe-angle yeprofayili yezinyo, intambo ye-BSPT ene-angle yeprofayili yezinyo ye-55 ° kunye nentambo ye-NPT ene-angle yeprofayili yezinyo ye-60 °.
BSPT Umsonto we-NPT
Jonga ukuma kwamazinyo: gweba ngokwemilo yezinyo phezulu kunye nezinyo ezantsi. Intambo ye-BSPT iphezulu ejikelezileyo kunye nezantsi, kwaye intambo ye-NPT ikwi-flat top and flat bottom.

Isigwebo sokugqibela
Ezi zixhobo zimbini zilandelayo ziyafuneka ukuqinisekisa ngokuchanekileyo uhlobo lomsonto.
Indlela yoku-1: sebenzisa igeyiji yomsonto kwaye ukhethe igeyiji yentambo ehambelanayo yokuqinisekisa okokugqibela. Umsonto olinganisiweyo ujijwe ngokugqibeleleyo ngegeyiji yomsonto. Ukuba imigaqo yokuhlola i-thread gauge ehambelanayo idluliselwe, ukucaciswa kwentambo yinkcazo yangempela yomsonto olinganisiweyo.
Indlela yesi-2: sebenzisa i-tooth gauge kwaye ukhethe i-tooth gauge ehambelanayo ukuze uthelekise de i-tooge gauge ifanelane ngokugqibeleleyo nomsonto olinganisiweyo, ngoko inkcazo yentambo yinkcazo yangempela yomsonto olinganisiweyo.
Ukongeza kwezi ndlela zingasentla, sinokujonga kwakhona imigangatho intambo ehambelanayo imisonto emithathu emva kokulinganisa intambo isithsaba ububanzi kunye caliper vernier kunye nokugweba taper intambo kunye intambo parallel, kwaye ufumanise ukuba iinkcukacha intambo kunye intambo isithsaba ubukhulu efanayo. njengomsonto olinganisiweyo kumgangatho wentambo ukuze kuqinisekiswe ngakumbi, kodwa isigwebo sokugqibela sisafuna uncedo lwegeyiji yomsonto kunye negeji yezinyo.
Xa uthenga izifakelo zemibhobho yeHikelok, kuyacetyiswa ukuba uyifake kwaye uyisebenzise kunye neevalvu zolawulo zeHikelok. Ungakhethaivalve yenaliti, ivalve yebhola, ivelufa yoncedo olulinganayo, ivalve yokulinganisa, khangela ivalve, iivalve ezininzi, inkqubo yesampula, njl., ukwenzela ukuba udibaniso lwenkqubo yamanzi lukhuseleke ngakumbi kwaye lusebenze.
Ukufumana iinkcukacha ezingaphezulu zoku-odola, nceda ubhekisele kukhethoiikhathalogukwiHikelok website esemthethweni. Ukuba unayo nayiphi na imibuzo yokukhetha, nceda uqhagamshelane Hikelok iiyure ezingama-24 abasebenzi online professional yokuthengisa.
