3/4 "Brass Gate Valve 3/4" Nqe: Dab tsi tsim qhov sib txawv loj ntawm qis thiab siab?
Feb 21, 2026
Lub lim tiam dhau los, kuv tau txais email los ntawm ib tus neeg siv khoom hauv South America. Nws xa ob daim duab ntawm ob3/4 "Brass Gate Valves. Lawv saib yuav luag zoo tib yam sab nraud, tab sis ib qho tau ua haujlwm ib txwm ua tau tsib xyoos, thaum lwm tus pib ntws dej tsuas yog peb lub hlis tom qab kev teeb tsa. Nws nug tias, "Vim li cas thiaj muaj qhov sib txawv loj hauv kev ua tau zoo ntawm ob yam uas zoo ib yam?" Qhov tseeb, nws tsis yog nws xwb; ntau tus neeg yuav khoom tau ntsib qhov xwm txheej no - xaiv qhov kev xaiv pheej yig dua thaum lub sij hawm sib piv tus nqi, tsuas yog kom them nyiaj ntau dua rau cov nqi zog thiab rov tsim kho dua. Hnub no, peb yuav tsis tham txog tus lej tshwj xeeb. Cia peb tham txog dab tsi cuam tshuam tus nqi ntawm 3/4 "txoj qhov rooj valve.
Cov ntawv tshaj tawm blog no yuav tsis qhia koj "ntau npaum li cas tus nqi" (tus nqi tooj liab hloov txhua hnub), tab sis nws yuav pab koj tsim cov txheej txheem kev txiav txim siab. Tom qab nyeem nws, koj yuav nkag siab qhov ntawd nrog tib yamBrass rooj vag valve 3/4 ", tus nqi sib txawv tuaj yeem ua tau ntau zaus, thiab koj yuav paub qhov sib txawv ntawm qhov twg. Lub sijhawm tom ntej koj tau txais cov lus hais, koj yuav tuaj yeem qhia qhov nrawm ntawm qhov twg "tsuas yog siv tau" thiab cov twg yog "tsim kom kawg."
1. Thawj Hurdle hauv3/4 "Brass Gate ValveNqe: Qhov chaw ntawm Brass Material
Qhib lub 3/4 " tooj dag rooj vag valve, ua ntej saib cov tooj dag.
Peb nyob rau hauv kev lag luam paub tias "tooj dag" tsis yog ib qho xwb. Qee cov tuam ntxhab siv cov tooj liab rov ua dua. Tom qab melting, nws muaj ntau yam impurities, cov qauv sab hauv yog ntxeem tau, thiab thaum lub sij hawm ua, qhov saum npoo yuav zoo li du, tab sis thaum txiav qhib, nws tuaj yeem nkaum cov xuab zeb qhov thiab porosity. Cov xuab zeb txhais li cas? Nws txhais tau hais tias ib zaug siv lub siab, cov dej xau tsuas yog lub sijhawm xwb.
Ntawm qhov tod tes, lwm hom chaw tsim khoom, zoo li peb, siv cov qauv qib forged tooj dag - piv txwv li, qis- txhuas txhuas uas ua tau raws li EU daim ntawv pov thawj. Cov khoom siv no yuav tsum tau tsim los ntawm cov txheej txheem kub forging, uas ua rau cov khoom siv siab ceev thiab cov qauv zoo li qub. Yog tias koj tuav ob qhov sib txawv 3/4 "tooj dag lub qhov rooj ntawm koj txhais tes thiab hnov lawv qhov hnyav, qhov sib txawv yog cov lus teb ncaj qha tshaj plaws. Qhov hnyav dua ib qho uas muaj nqi ntau dua.
2. Qws thiab rooj vag: Qhov Tsis pom qhov twg cov nqi zog ntxiv
Yog tias lub cev lub cev yog lub cev pob txha, ces lub qia thiab lub rooj vag yog lub plawv. Tus nqi sib txawv ntawm cov khoom no feem ntau txiav txim siab seb lub valve yuav kav ntev npaum li cas.
- Lub Valve:Ntawm pheej yig li qub, cov qia threads ncaj qha txiav los ntawm lub tshuab dhos. Cov xov yog ntiav, nto yog ntxhib, thiab lawv hnav tawm tom qab siv ob peb. Tom qab hnav, tus kov tig dawb, thiab lub valve yuav tsis kaw tag nrho. Ntawm qhov zoo, ruaj khov 3/4" tooj dag rooj vag valve, qia threads yog tsim los ntawm cov txheej txheem dov. Rolled threads muaj cov hlau txuas txuas ntxiv, siab dua qhov tawv tawv, thiab zoo dua hnav tsis kam - lawv yuav tsis "dawb" txawm tias tom qab ntau txhiab qhib - kaw cycles.
- Rooj vag:Ntawm qis- cov nqi qis, lub rooj vag thiab lub rooj zaum valve feem ntau yog tshuab sib cais thiab tsuas yog sib npaug; lawv ua tsis tau ib tug zoo meej foob. Kev lag luam- tus qauv kev coj ua yog sib npaug lapping - txhua lub rooj vag yog lapped tshwj xeeb rau nws lub rooj sib txuam kom ntseeg tau tias ob qhov chaw sib khi ua ke zoo kawg nkaus. Cov txheej txheem no yuav tsum tau siv zog ua haujlwm thiab sijhawm, yog li tus nqi sib txawv. Tab sis qhov tshwm sim yog: drip- nruj kaw- tawm.
3. Siv rau Cov Txheej Txheem Feem Ntau ntawm Brass Gate Valve 3/4 "
Rau koj txoj kev yooj yim thaum kuaj xyuas cov lus qhia tshwj xeeb, ntawm no yog cov npe ntawm cov kev txwv tsis sib xws hauv kev lag luam:
| Yam khoom Parameter | Common Specifications | Kev piav qhia |
|---|---|---|
| Hom kev sib txuas | Xov (NPT / BSP) | Cov qauv Asmeskas feem ntau siv NPT, Asian / European kev lag luam feem ntau siv BSP. Paub meej thaum nug. |
| Hom kev ua haujlwm | Handwheel / Kov | Lub 3/4 "qhov loj me feem ntau tuaj nrog cam khwb cia hlau tes los yog zinc alloy kov. |
| Kev ntsuas siab | 200 WOG (kwv yees . 1.6 MPa) | Feem ntau rau cov dej txias txias. Qee cov qauv txhawb zog tuaj yeem tiv taus siab dua. |
| Siv tau qhov kub thiab txias | -20℃~ 150 degree | Haum rau dej, tsis yog -cov pa roj corrosive, thiab roj. |
| Ntsej muag - rau - Lub ntsej muag Dimension | Ua raws li DIN / ANSI cov qauv | Qhov ntev sib txawv raws li cov qauv sib txawv, cuam tshuam rau kev teeb tsa cov kav dej. |
| Stem Sealing | PTFE ntim + Gland | Tiv thaiv tawm xov xwm tawm raws li qia. |
4. Qhov twg yog Brass Gate Valve 3/4 "Siv?
Lub 3/4 " tooj dag rooj vag valve, thaum qhib tag nrho, muaj kev tiv thaiv me me rau qhov nruab nrab, ua rau nws tsim nyog raws li kev sib cais valve, tab sis tsis zoo rau kev tswj xyuas ntau zaus.
Cov xwm txheej ntawm daim ntawv thov feem ntau suav nrog:
- Chaw Ua Haujlwm Dej Chaw Nyob:Tom qab lub ntsiab dej ntsuas dej, vaj dej kais cov ntsiab lus.
- Kev lag luam me me:Cov chaw tso dej tso dej hauv txoj kev -cov khw muag khoom, cov tsev nyob.
- HVAC Systems:Kev rho tawm li qub nyob rau qis - siab cua sov rov qab kav.
- Agricultural Facilities:Ceg kab tswj dej hauv tsev cog khoom irrigation.
Hauv cov ntawv thov no, nws tsis tas yuav qhib / kaw sai li lub pob valve, tab sis nws qhov txiaj ntsig yog nyob rau hauv qhov qhib tag nrho thaum qhib tag nrho, uas tsis txwv kev ntws.
5. Cov lus qhia rau cov neeg yuav khoom: Saib ntawm qhov tsis sib xws, Kuj saib cov txheej txheem
Lwm zaus koj tau txais ibquotation rau tooj dag rooj vag valve3/4", tsis txhob saib tag nrho, sim nug: "Puas yog cov qia threads dov los yog txiav? Cov khoom siv tooj dag siv qib dab tsi?” Yog tias lwm tus tuaj yeem sib tham txog qhov no nrog koj kom meej, nws qhia tau hais tias lawv muaj kev nkag siab zoo ntawm lawv cov khoom, thiab cov khoom zoo yuav ua rau muaj kev ntseeg siab.
