Ntsia hlau xov, nrog rau cov tshuab txhua hnub, domestic thiab txawv teb chaws rau lub sij hawm ntev, metric thiab imperial, ncaj cone, kaw thiab tsis-sealed, sab hauv thiab sab nrauv, 55 degrees thiab 60 degrees. Hauv luv, nws yog feem ntau messed. Siv nws ib zaug los xyuas txij thaum pib mus txog thaum xaus. Kuv kuj tuaj yeem sau cov ntsiab lus ntawm no. Kuv vam tias nws yuav pab tau.
Kuv txoj kev yog luam tawm thiab muab tso rau ntawm ib sab ntawm lub rooj, thiab xyuas nws txhua lub sijhawm thaum kuv siv nws. Tom qab ib tug ntev lub sij hawm, kuv yuav nco ntsoov nws.
NPT yog lub hom phiaj dav dav Asmeskas tus qauv tapered yeeb nkab xov nrog lub kaum sab xis ntawm 60 degree
PT hniav yog ib qho imperial tapered xov, thiab lub kaum sab xis ntawm tus hniav yog 55 degree, uas yog feem ntau siv nyob rau hauv sealing. Lub British yeeb nkab xov yog ib tug zoo xov, vim hais tias cov hniav tob ntawm cov ntxhib xov yuav ua rau txo lub zog ntawm cov yeeb nkab nrog lub sab nraud txoj kab uas hla ntawm cov xov txiav.
PF cov hniav yog cov kab sib txuas rau cov kav dej.
G yog 55-degree tsis-threaded sealing yeeb nkab xov, uas belongs rau Whitworth xov tsev neeg. Cuam tshuam raws li G sawv cev rau cylindrical xov, G yog lub npe dav dav ntawm cov yeeb nkab xov (Guan), thiab kev faib ntawm 55 thiab 60 degrees yog ua haujlwm.
ZG feem ntau hu ua yeeb nkab cone, uas yog, cov xov yog ua tiav los ntawm lub conical nto. Cov yeeb nkab dej dav dav yog zoo li no. Lub teb chaws qub qauv yog cim raws li Rc
Cov xov metric yog sawv cev los ntawm lub suab, thiab Asmeskas thiab Askiv xov yog sawv cev los ntawm cov xov tooj ntawm ib nti. Qhov no yog qhov sib txawv loj tshaj ntawm lawv. Cov xov metric yog 60-degree equilateral hniav hom, thiab British system yog ib qho isosceles 55-degree hniav hom. American xov 60 degrees. Siv metric units rau metric threads thiab imperial units rau US thiab British threads.
Cov yeeb nkab xov yog tsuas yog siv rau kev sib txuas ntawm cov kav dej, thiab nws cov xov sab hauv thiab sab nraud tau sib raug zoo, thiab muaj ob hom yeeb nkab ncaj thiab tapered yeeb nkab. Lub nominal txoj kab uas hla yog hais txog txoj kab uas hla ntawm cov yeeb nkab txuas, pom tseeb qhov loj txoj kab uas hla ntawm cov xov yog loj dua lub nominal txoj kab uas hla.
1/4, 1/2, 1/8 yog cov nominal diameters ntawm British xov, nyob rau hauv nti.
1. Inch unified thread
Dav siv nyob rau hauv nti system lub teb chaws, hom xov no muab faib ua peb series: coarse xov series UNC, nplua xov series UNF, ntxiv zoo xov series UNFF, ntxiv rau ib tug taag pitch series UN.
Marking method: xov txoj kab uas hla - tus naj npawb ntawm cov hniav ib nti series code - precision qib
Piv txwv: Coarse series 3/8—16UNC—2A
Fine hniav series 3/8—24UNF—2A
Ntxiv cov hniav zoo nkauj 3/8—32UNFF—2A
Tsau suab series 3/8-20UN-2A
Thawj tus lej 3/8 qhia txog sab nraud ntawm cov xov, chav tsev yog nti, thiab hloov mus rau metric unit mm yog muab faib ua 25.4, uas yog, 3/8 × 25.4=9.525mm; tus lej thib ob thiab thib peb 16, 24, 32, thiab 20 yog Tus naj npawb ntawm cov hniav ib nti (tus naj npawb ntawm cov hniav ntawm qhov ntev ntawm 25.4mm); ntxiv WeChat: Yuki7557 xa ib daim qauv ntawm macro program tutorial, cov ntawv code tom qab tus lej thib peb yog UNC, UNF, UNFF, UN yog tus lej lej, thiab ob tus lej kawg yog 2A rau qib raug.
2. Kev hloov pauv ntawm 55 degree cylindrical yeeb nkab xov
55 degree cylindrical yeeb nkab xov yog muab los ntawm lub nti system, tab sis nws yog dav siv nyob rau hauv ob qho tib si metric thiab nti lub teb chaws. Nws yog siv los txuas cov yeeb nkab txuas thiab cov kav dej rau kev xa cov kua dej, gases, thiab txhim kho cov xov hlau. Txawm li cas los xij, cov lis dej num ntawm ntau lub teb chaws txawv, thiab lawv yuav tsum tau nias Cov lej txawv teb chaws hauv lub rooj (cov lus sib piv) tau hloov mus rau hauv Suav cov lej, thiab 55 degree cylindrical yeeb nkab xov codes ntawm ntau lub teb chaws tau teev nyob rau hauv cov lus hauv qab no.

Xov Classification
Raws li kev siv cov xov sib txawv, nws tuaj yeem muab faib ua:
1. International Metric Xov System
Cov xov tau txais los ntawm kuv lub teb chaws tus qauv CNS. Sab saum toj ntawm tus hniav yog tiaj tus thiab yooj yim tig, thiab hauv qab ntawm cov hniav yog arc-puab los ua kom lub zog ntawm cov xov. Lub kaum sab xis yog 60 degrees, thiab qhov tshwj xeeb yog sawv cev los ntawm M. Metric threads tuaj yeem muab faib ua ob hom: xov coarse thiab xov zoo. Cov ntawv sau xws li M8x1.25. (M: Code, 8: Nominal diameter, 1.25: Pitch).
2. American Standard Xov (American Standard Thread)
Ob sab saum toj thiab hauv paus ntawm cov xov yog tiaj tus, nrog lub zog zoo dua. Lub kaum sab xis kuj tseem yog 60 degrees, thiab cov lus qhia tshwj xeeb qhia hauv cov hniav ib nti. Cov xov no tuaj yeem muab faib ua peb qib: xov coarse (NC), xov zoo (NF), thiab xov ntxiv zoo (NEF). Cov ntawv sau xws li 1/2-10NC. (1/2: sab nraud; 10: hniav ib nti; NC code).
3. Unified Thread (UnifiedThread)
Kev sib koom ua ke los ntawm Tebchaws Meskas, United Kingdom, thiab Canada, nws yog cov xov xov uas siv ntau tshaj plaws tam sim no.
Lub kaum sab xis kuj tseem yog 60 degrees, thiab cov lus qhia tshwj xeeb qhia hauv cov hniav ib nti. Cov xov no tuaj yeem muab faib ua cov xov ntxhib (UNC); xov zoo (UNF); xov tooj zoo ntxiv (UNEF). Cov ntawv sau xws li 1/2-10UNC. (1/2: sab nraud; 10: hniav ib nti; UNC code)
4. V-zoo li tus xov (ntse VThread)
Ob sab saum toj thiab hauv paus yog taw tes, lub zog tsis muaj zog, thiab nws tsis siv ntau zaus. Lub kaum sab xis yog 60 degrees.
5. Whitworth Xov
Cov xov tau txais los ntawm British National Standards. Lub kaum sab xis yog 55 degrees, thiab lub cim yog "W". Haum rau dov txoj kev tsim. Cov ntawv sau xws li W1/2-10. (1/2: sab nraud; 10: hniav ib nti; W code).
6. Round xov (KnuckleThread)
Nws yog tus qauv xov teeb los ntawm DIN hauv lub teb chaws Yelemees. Nws yog qhov tsim nyog rau kev sib txuas ntawm lub teeb qhov muag teev thiab cov raj roj hmab. Lub cim yog "Rd".
7. Tube xov (PipeThread)
Rau cov xov siv los tiv thaiv kom tsis txhob xau, ntxiv WeChat: Yuki7557 xa ib daim ntawv theej ntawm macro program tutorial, uas feem ntau yog siv los txuas cov roj av lossis kua yeeb nkab fittings. Lub kaum sab xis yog 55 degrees, uas tuaj yeem muab faib ua cov yeeb nkab ncaj cov lej "PS, NPS" thiab inclined yeeb nkab xov code "NPT", thiab lub taper yog 1:16, uas yog, 3/4 nti ib ko taw.
8, square xov (SquareThread)
Kev sib kis tau zoo yog qhov siab, qhov thib ob tsuas yog lub pob xov, thiab nws tsis tuaj yeem hloov kho nrog cov txiv ntoo tom qab hnav thiab tsim kua muag, uas yog nws qhov tsis zoo. Feem ntau siv rau cov ntsia hlau ntawm lub vise thiab xov ntawm crane.
9. Cov xov Trapezoidal
Kuj tseem hu ua Acme thread. Kev sib kis tau zoo yog me ntsis me dua ntawm cov xov xwm square, tab sis nws tuaj yeem hloov kho nrog cov txiv ntoo tom qab hnav. Lub kaum sab xis ntawm lub metric system yog 30 degrees, thiab xov lub kaum sab xis ntawm lub imperial system yog 29 degrees. Feem ntau siv rau cov ntsia hlau ntsia hlau ntawm lub tshuab dhos. Lub cim yog "Tr".
10. Npuag xov
Kuj hu ua oblique xov, nws tsuas yog haum rau kev sib kis ntawm ib txoj kev. Xws li cov ntsia hlau jacks, pressurizers, thiab lwm yam. Lub cim yog "Bu".
11. Pob xov
Cov xov uas muaj kev sib kis tau zoo tshaj plaws yog qhov nyuaj rau kev tsim khoom thiab tus nqi yog siab heev, yog li nws yog siv nyob rau hauv precision machinery. Xws li cov hlau lead ntawm CNC tshuab cuab yeej.
Sawv cev ntawm nti bolts:
LH 2N 5/8 × 3 - 13UNC-2A
(1) LH yog sab laug (RH yog txoj cai xov, uas tuaj yeem raug tshem tawm).
(2) 2N ob txoj xov.
(3) 5/8 nti xov, 5/8 "OD.
(4) 3 Bolt ntev 3 ".
(5) 13 threads muaj 13 threads ib nti.
(6) UNC unified txheem xov coarse xov.
(7) Qib 2 haum, xov sab nraud (3: Tight haum; 2: Nruab nrab haum; 1: Loose haum) A: Cov xov sab nraud (tuaj yeem tshem tawm) B: Internal xov
Imperial xov:
Qhov loj ntawm cov xov ntiv tes feem ntau yog qhia los ntawm cov xov tooj ntawm ib nti ntawm qhov ntev ntawm cov xov, hu ua "xov ib nti", uas yog sib npaug ntawm qhov sib npaug ntawm lub suab. Piv txwv li, ib tug xov nrog 8 hniav ib nti muaj ib lub suab ntawm 1/8 nti.
