Shims yog zoo li qub cov khoom ntim uas daws "khiav, khiav, tso, tawm." Vim tias muaj ntau cov ntaub ntawv ntawm cov ruaj ntseg zoo li qub, raws li cov ntaub ntawv foob no, muaj qhov tshwm sim los ntawm cov qauv dav hlau, cov nplaum, cov ntaub qhwv lub plawv, cov nplaum qhwv, O-rings, thiab ntau yam khoom ntim. Qhov kev txhim kho ntawm cov gasket yuav tsum tau ua nyob rau hauv cov flange kev sib txuas ntawm cov qauv los yog cov qhov sib txuas ntawm cov hlua khi, qhov chaw ruaj khov zoo li qub thiab cov gasket raug tshawb xyuas, thiab lwm qhov chaw muaj lub voj voos.
Sealing gasket
1. Ua ntej siv lub tshuab ua roj, siv ib txheej ntawm graphite hmoov los yog graphite hmoov nrog cov roj cav (lossis dej) rau qhov sib txoos ntawm qhov sib txuam ntawm qhov sib tsoo, av khov, cov txhauv, thiab cij thiab lub ncuav. Lub gasket thiab graphite yuav tsum ceev kom huv.
2, lub gasket ntsia rau ntawm qhov chaw ntub dej yuav tsum yog nyob rau hauv qhov tseeb, tsis tuaj yeem txuam yuaj, tsis tuaj yeem nkag mus rau hauv lub tshav pob los yog lub xub pwg. Lub cev diameter ntawm lub thom khwm yuav tsum loj dua lub puab diam iav ntawm qhov sib tsoo, thiab lub sab nraud yuav tsum me ntsis me tshaj lub npoo ntawm lub sealing ntom, thiaj li los xyuas kom meej tias lub gasket nias tusyees.
3, lub installation ntawm lub gasket tsuas yog pub rau nruab ib qho xwb, tsis txhob cia ob los yog ntau daim ntawm qhov chaw ntub dej kom tshem tawm qhov sib txawv nruab nrab ntawm ob qhov chaw ntim.
4. Cov pa roj hmab yuav tsum muab ntim kom khi kom cov npog sab hauv thiab sab nraud ntawm sib sib zog sib dhos, thiab ob sab kawg ntawm lub qhov roj hmab tsis tuaj yeem tiv tauj rau sab hauv qab ntawm qhov zawj.
5, O-ring installation, ntxiv rau lub nplhaib thiab zawj yuav tsum tau ua raws li cov qauv tsim, tus nqi ntawm qhov kev sib txuam yuav tsum tsim nyog, hlau hollow O-nplhaib dav thaj ntawm 10% mus rau 40%, rubber O-ring compression deformation , cylindrical surface Qhov chaw foob hauv lub sijhawm 13% ~ 20%; dav hlau zoo li qub ntim ntawm 15% ~ 25%. Rau siab siab, kev siv lub tshuab nqus dej deev yuav tsum siab zog. Nyob hauv thaj chaw ntawm txoj kev cog lus, qhov me me tus nqi tsawg tshaj plaws, qhov zoo, thiab tuaj yeem ntev mus rau O-Ring.
6. Ua ntej lub qhov gasket nyob rau hauv lub hau npog, lub hau yuav tsum nyob hauv txoj kev qhib kom tsis txhob cuam tshuam rau qhov kev teeb tsa thiab kev puas tsuaj rau lub valve. Thaum muab daim ntaub npog pov tseg, tsis txhob siv txoj hau kev thawb tawm los ua kom sib txuas nrog lub gasket kom lub pob taws tsis tuaj yeem hloov los yog khawb. Thaum kho qhov chaw ntawm lub hau, tsa lub hau kom qeeb thiab kom nws maj mam txo nws.
7. Kev siv lub nplaum los yog cov hlua khi yuav tsum yog tias qhov gasket yog nyob rau ntawm txoj kab tav (lub hau npog ntsia thawv, thiab txoj hlua ntawm txoj hlua yuav tsum tsis txhob siv nrog lub raj txuas). Xov zawm yuav tsum yog symmetrical, tig, thiab hnav. Lub bolts yuav tsum yog tag nrho, zoo, thiab dawb los ntawm loosening.
8. Ua ntej yuav muab cov pa roj pleev kom nruj nruj, lub siab, kub, cov khoom nruab nrab, cov yam ntxwv ntawm cov khoom siv roj yuav tsum raug to taub meej, thiab yuav tsum txiav txim siab ua ntej. Lub zog quab yuam yuav tsum tau ua kom tsawg dua thaum qhov kev sim siab tsis tuaj yeem ntws (ntau zaus ua ntej zawm quab yuam tau yooj yim lub pob tawb thiab ua rau lub gasket poob nws cov resilience).
9. Tom qab cov roj av tso zis, nws yog qhov yuav tsum tau xyuas kom muaj qhov sib txawv ntawm qhov sib txuas ntawm qhov chaw sib txuas los npaj rau chav pw ua ntej zawm thaum lub thawv ntub tawm.
10. Thaum ua haujlwm kub siab, lub bolt yuav ua rau kub kub, ua rau muaj kev ntxhov siab, ua kom deformation loj, ua rau muaj pa tawm ntawm lub gasket, qhov kub dua. Conversely, nyob rau hauv qis kub, cov bolts yuav shrink thiab yuav tsum tau loosened. Qhov kub ceev yog qhov siab, qhov ntoo ntawm cov ntoo txias yog qhov siab, thiab qhov kub ceev thiab qhov txias yuav tsum tau ua tom qab ua kom kub li 24 teev.
11. Thaum cov hniav sib khi siv lub thawv ua kua, nws yuav tsum ntxuav los yog ntim kho. Txoj hlua khi seev yuav tsum zoo ib yam li tom qab sib tsoo, txheej nplaum yuav tsum tsis tsim (nplaum yuav tsum tau ua kom haum rau kev ua haujlwm), sim tawm cais cua, kua nplaum feem ntau yog 0.1 ~ 0.2 hli. Ntiv nplhaib yog tib yam li lub dav hlau ntim. Ob qhov chaw yuav tsum tau coated. Thaum nws yog screwed, nws yuav tsum nyob rau hauv ib txoj hauj lwm ntsug kom pab txhawb cov pa tawm. Lub kua nplaum yuav tsum tsis txhob ntau dhau lawm, yog li tsis txhob txeej av ntawm lwm qhov chaw hauv lub tshuab.
12. Thaum siv teflon-coated nyoos kab xev rau txoj hlua khi, pib lub ntsiab lus ntawm zaj duab xis yuav tsum thinned thiab glued ntawm thread thread; tom qab ntawd lub qhov taw qhia tshaj qhov tshaj tawm ntawm qhov pib yuav tsum tau muab tshem tawm kom ua rau zaj yeeb yaj kiab ua rau cov xov yuav ntim zoo li cas. Nyob ntawm qhov kev xuv tooj, nws feem ntau yog mob nrog 1 mus rau 3 lem. Cov kev taw qhia ntawm cov cua yuav tsum ua raws li cov ntsia hlau-hauv kev taw qhia, thiab qhov kawg taw tes yuav tsum yog overlapped thaum pib taw tes; zaj duab xis yuav tsum maj mam rub mus rau hauv ib lub zoo nkauj zoo li ntawd lub thickness ntawm zaj duab xis yog Uniform. Ua ntej screwing nyob rau hauv, zaj duab xis nyob rau ntawm lub kawg ntawm cov xov yog nias ua ke thiaj li hais tias zaj duab xis yog screwed rau hauv Internal xov nrog cov xov; thaum nws yog screwed nyob rau hauv, nws yuav tsum qeeb, thiab lub zog yuav tsum tsis tau; tom qab zawm, tsis txav dua, tab sis kuj tsis txhob tig, txwv tsis pub nws yuav paim yooj yim.
Cov teebmeem saum toj no hais txog kev tsim kho kev lag luam, txawm tias phau ntawv qhia yuav ua li cas, tiam sis cuaj hlau zoo li Xiaobian xav, cov txheej txheem txhim kho rau cov khoom siv khoob fais fab tseem yuav tsum tau saib, ntawm no yog qhia rau koj siv.
