hlau sealing npauj npaim valve
cov khoom piav qhia
Kev tuav flange hmetal foob flange npauj npaim valve txais yuav qhov tseeb J-shaped elastic sealing nplhaib thiab triple eccentric multi-layer hlau nyuaj foob qauv. Nws yog dav siv nyob rau hauv metallurgy, hluav taws xob fais fab, roj av, tshuaj lom neeg kev lag luam, kev siv dej thiab kev tso dej thiab kev tsim kho hauv nroog uas qhov nruab nrab kub tsawg dua lossis sib npaug li 425 degree. Nyob rau hauv industrial pipelines, nws yog siv los tswj kev khiav thiab nqa thiab tawg kua.
Performance nta
1. Lub valve no txais yuav peb-eccentric sealing qauv, uas yuav luag tsis hnav ntawm lub rooj zaum valve thiab npauj npaim phaj, thiab muaj kev sib khi ua haujlwm nruj dua li nws raug kaw.
2. Lub nplhaib sealing yog ua los ntawm cov hlau tsis muaj steel, uas muaj ob qhov zoo ntawm cov hlau tawv sealing thiab elastic sealing. Nws muaj kev ua tau zoo sealing tsis muaj teeb meem nyob rau hauv qhov qis lossis siab kub, thiab muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab lub neej ua haujlwm ntev.
3. Lub sealing nto ntawm tus npauj npaim phaj yog ua los ntawm cobalt-based hard alloy surfacing. Lub sealing nto yog corrosion-resistant thiab muaj lub neej ua haujlwm ntev.
4. Lub valve no muaj ob txoj kev sib khi ua haujlwm. Nws tsis txwv los ntawm kev khiav dej num ntawm qhov nruab nrab lossis cuam tshuam los ntawm txoj haujlwm spatial thaum lub sijhawm teeb tsa. Nws tuaj yeem ntsia tau rau txhua qhov kev taw qhia.

Cov yam ntxwv thiab kev siv
Hlau foob npauj npaim valve series khoom yog lub neej ntev, txuag hluav taws xob npauj npaim li qub. Cov khoom ua raws li lub teb chaws tus qauv JB/T8527-97 (hlau foob npauj npaim valve), GB / T13927-92 (universal valve siab test) cov qauv thiab lwm yam qauv rau li qub. Cov khoom no muaj lub cev valve, npauj npaim phaj, sealing nplhaib, kis mechanism thiab lwm yam tseem ceeb. Nws cov qauv yog tsim los siv lub hauv paus ntsiab lus ntawm peb-dimensional eccentric, thiab ib tug tshiab ua technology sib xws nrog elastic sealing thiab tawv thiab mos multi-layer sealing enables npauj npaim valve kom txo tau nws torque quab yuam thaum lub sij hawm ua hauj lwm, ua kom tiav zog-txuag thiab txuag zog. . Qhov no ua kom muaj kev ntseeg tag nrho ntawm npauj npaim valve nyob rau hauv cov nqe lus ntawm corrosion kuj, kub tsis kam thiab hnav tsis kam. Qhov npauj npaim valve no yog tsim los siv rau hauv cov zaub mov, tshuaj, kev lag luam petrochemical, fais fab nroj tsuag, steel nroj tsuag, muaj kev tiv thaiv ib puag ncig kev kho dej thiab cov tsev siab siab, raws li cov cuab yeej zoo tshaj plaws los tswj cov dej ntws thiab txiav tawm cov dej hauv cov kav dej thiab cov kav dej.
Peb-eccentric npauj npaim valve
Yog hais tias lub valve qia axis deviates los ntawm lub disc center thiab lub cev chaw nyob rau tib lub sij hawm, thiab lub valve lub rooj sib hloov axis muaj ib tug tej lub kaum sab xis nrog lub valve lub cev channel axis, nws yog hu ua triple-eccentric npauj npaim valve.
Thawj eccentricity: lub valve ncej nyob tom qab lub valve phaj ncej, tso cai rau lub foob kom nruj ib puag ncig thiab hu rau tag nrho lub rooj zaum valve.
Qhov thib ob eccentricity: lub centerline ntawm lub valve ncej deviates los ntawm lub centerline ntawm cov yeeb nkab thiab valve, uas tsis txhob cuam tshuam los ntawm qhib thiab kaw ntawm lub valve.
Qhov thib peb eccentricity: lub valve lub rooj cone axis deviates los ntawm lub valve ncej centerline, uas yuav tshem tawm kev sib txhuam thaum lub sij hawm kaw thiab qhib cov txheej txheem thiab ua tau ib tug uniform compression sealing nyhuv nyob ib ncig ntawm lub rooj zaum valve.
Cov npauj npaim li qub txhua tus siv qhov chaw sib khi, tab sis qhov tshwm sim ntawm triple eccentric npauj npaim li qub tau hloov pauv cov qauv kev sib khi ntawm cov npauj npaim li qub, thiab qhov chaw sib khi tau dhau los ua kev sib khi.
Ib qho yooj yim piav qhia yog tias triple eccentric npauj npaim valve tsis tso siab rau lub elastic deformation ntawm lub rooj zaum valve kom ua tiav sealing, tab sis cia siab rau qhov sib chwv siab ntawm npauj npaim phaj sealing nto thiab lub rooj zaum valve kom ua tiav sealing.
Nyob rau hauv txoj kev no, peb-eccentric qauv ntawm ib-eccentric npauj npaim valve tsis tsuas yog daws qhov teeb meem ntawm loj to ntawm lub rooj zaum hlau, tab sis kuj muaj zog high-pressure thiab high-temperature kuj vim hais tias qhov kev sib cuag nto siab yog proportional rau lub nruab nrab siab. Qhov kev ua tau zoo ntawm triple eccentric npauj npaim valve ua rau nws siv dav hauv cov roj kav dej txiav, cov nroj tsuag hlau metallurgical, thiab cov kav dej loj. Kev faib tawm thiab txiav tawm, kev hloov kho nruab nrab thiab txiav tawm ntawm cov khoom siv tshuaj ua kom zoo, kev hloov dej hauv dej thiab qhov hluav taws xob thiab kev txiav tawm ntawm cov khoom siv kho dej, cov dej txias ntawm qhov chaw nres tsheb thermal. Natural gas, alkali kua, dej hiav txwv, kua qaub thiab lwm yam lag luam.
