Intambo ye-NPT ngumgangatho waseMelika we-60 ° intambo yombhobho wetaper.Ifomyula yokubala i-warp yomsonto yile:Ifomula yedayamitha ephakathi yomsonto yile: D2=d2=D-0.8XPPIfomula yendlela yomsonto yile: D1=d1=D-1.6XPImowudi yokulingana komsonto ngu. Ukwahlulwe ngokwe-cone-post fit okanye i-cone-cone fit.Ubude bomsonto u-L sisimbuku sobude obuchanekileyo bobude obuncinci obusebenzayo obungekho ngaphantsi komgama wereferensi + yesibonelelo sendibano. Emva kokulungiswa komsonto, xa imveliso egqityiweyo igqityiwe, uphawu olucacileyo lomsonto kufuneka luphawulwe isiphelo sobuso bomsonto okanye ezinye iindawo ezitsala amehlo, ezinje: 4-8NPT-LHUkutywinwa kwalo msonto kugqitywe ngokutywina phakathi kwemisonto.Xa kukho impikiswano malunga nokuhlolwa kwesixhobo sokulinganisa intambo yeplagi, iziko lovavanyo lobungcali liya kongamela.
Ukuhlolwa kwentambo ye-TBG
Intambo ye-TBG yintambo yoqhagamshelo lombhobho wepetroleum, ifana nentambo yombhobho we-oyile, umgangatho wayo ngu: API-5B, intambo ye-TBG yahlulwe ibe yingqimba (EUE EU) kwaye ayishiyi (NUE NU) iindidi ezimbini, intambo yeAngle yi-60 ° i-taper yi-1:16.Iinkcukacha zomsonto ongacingelwayo zimi ngolu hlobo lulandelayo: 1.05TBG;1.315 TBG;1.660 TBG;1.900 TBG;22/8TBG;27/8TBG;31/2TBG;41/2TBG.I-UPTBG igxininise (EUE) intambo ye-TBG, amazinyo e-8 ngexesha ngalinye, iinkcukacha zi: 1.05UPTBG 1.05UPTBG;1.315 UPTBG;1.660UP TBG;1.900UPTBG;2 2/8UPTBG;27/8UPTBG;31/2UPTBG;4UPTBG.41/2UPTBG
.A: Ukulungiswa ngaphambi kokuhlolwa: 1:16 igeji yokukhanya, iplagi yeringi yegeji.60° teether gauge.CB/T 12726-2002 (S) .2002
Ukuhlolwa kwentambo yaseMelika:
(1)I-engile yezinyo i-Angle yomsonto waseMelika yi-60 °, eyahlulahlulwe yaba: i-UNS erhabaxa, i-UNF entle, i-ultra-fine UNEF, i-universal UNC intambo erhabaxa.I-pitch ibonakaliswa kwinani lamazinyo kwi-25.4mm nge-intshi nganye.Iindlela zokumakisha ezifana ne:7/8-9UNC.I-2B.Ibakala lentambo yaseMelika yahlulwe ibe yi-A kunye ne-B iindidi ezimbini, intambo isetyenziswa kuphela kwintambo yangaphandle, yahlulwe ibe ngu-1A;2A;3A, ibakala lomsonto wangaphakathi limelwe ngu-B, nalo lahlulwe ngo-1B;2B;3B.I-1A1B inomgangatho ophezulu wentambo kwaye isetyenziselwa i-US ornance okanye ezinye iinjongo ezizodwa.I-2A2B ifanelekile kwimisonto yokudibanisa ngokubanzi kwaye ingagqunywa kumphezulu wentambo.Indlela yokuhlola: i-diameter enkulu ye-United States thread;Idayamitha encinci;I-warp ephakathi ingaguqulelwa kumaxabiso e-metric M.Emva koko ngokwendlela yokuhlola i-metric M intambo yokuvavanya ububanzi obukhulu bomsonto waseMelika;Idayamitha encinci;Idayamitha ephakathi okanye eneenkcukacha ezifanayo zeringi yeplagi yegeyiji ebanzi kunye negeji yokumisa ukujonga;Intsalela iya kuhlolwa ngokuhambelana nolunye uhlobo kunye nokunyamezelana kwesikhundla kunye nobukhulu obuchazwe kwinkqubo yokuzoba.Indlela yokuguqula intambo yaseMelika ibe yi-metric M intambo ngolu hlobo lulandelayo:Njenge: 7/8-9UNC.2B Idayamitha yayo engummiselo: 22.225 mm.I-pitch yayo yi: 2.822mm, kwaye ububanzi bayo bu-22.225 (0.6495 x 2.822) = 20.391 mm. Imveliso yentambo yaseMelika egqityiweyo: Isibonisi somsonto wemveliso kufuneka senziwe kumphezulu wemveliso ngaphambi kokuba igcinwe.
LP intambo yombhobho yeoli
uhloloLP umsonto wombhobho weoyile;Ngokufana nentambo yombhobho ye-NPT ye-vertebral ene-contour yentambo ye-Angle ye-60 ° kunye ne-taper ye-1:16.Umahluko phakathi kwayo kunye nentambo ye-NPT ye-vertebral canal kukuba ukuphakama kwentambo ye-LP yenkcazo efanayo iphantsi kune-NPT intambo, ukuphakama kwentambo ye-LP yi-0.073P, ngelixa ukuphakama kwentambo ye-NPT yi-0.033P, oko kukuthi, i-tip. ye-LP intambo ithe tyaba kakhulu kunaleyo yentambo ye-NPT.Kwaye intambo ye-LP ine-stop, inokukhusela ngokufanelekileyo intambo emonakalweni, itywina intambo ye-LP itywinwe ngomgca wezinyo, ngoko ukuchaneka kokucubungula kuphezulu kuneemfuno zentambo ye-NPT, kunye nobude obusebenzayo be-LP intambo ide kune-NPT. , okwandisa ubunzima bokucubungula.Ukuhlolwa kwentambo ye-LP: LP;Ukuhlolwa kwemisonto ngokwesiseko kuyafana nolo lwemisonto yeNPT.Idinga 1:16 igeyiji yokukhanya, iplagi edityanisiweyo yeringi yegeyiji.Igeyiji yamazinyo, irula yobude bezinyo, njl.njlOku kunokutshekishwa kumgangatho we-API-5B womsonto.Ngethuba lokuhlola kunye nokuvavanya, ukwamkelwa kobukhulu obufanelekileyo kufuneka kuqhutywe ngokwenkqubo yokudweba kunye nobukhulu obufunwa yimvumelwano.Iimveliso ezifanelekileyo kufuneka ziphawulwe kwinkcazo yentambo yokutsala amehlo.
