Valve sealing nto to kho txoj kev Puas yog lub valve yuav tsum tau nruab bypass valve cov hauv paus ntsiab lus thiab Chaw?

Ntsia lub bolts sib npaug thiab symmetrically. Yog tias tsim nyog, siv lub torque wrench. Lub preload yuav tsum tau raws li qhov yuav tsum tau thiab tsis loj los yog me me. Yuav tsum muaj qee qhov kev tshem tawm ntawm qhov sib koom ua ke ntawm flange thiab xov. Lub rooj sib dhos gasket yuav tsum tau ua raws li qhov chaw nruab nrab thiab lub zog yuav tsum tsis sib xws. Lub gasket lap thiab ob gasket tsis pub.
Ua rau:
1, sealing nto sib tsoo tsis sib xws, tsis tuaj yeem tsim txoj kab ze.
2. Kev sib txuas ntawm lub qia thiab qhov kaw yog raug tshem tawm, tsis ncaj los yog hnav.
3, lub valve qia dabtsi yog khoov los yog sib dhos tsis raug, yog li ntawd lub kaw qhov yog skewed los yog tsis nyob rau hauv nruab nrab.
4. Kev xaiv tsis raug ntawm sealing nto khoom zoo lossis tsis xaiv lub valve raws li kev ua haujlwm.
Txoj kev tiv thaiv thiab tshem tawm:
1. Xaiv cov khoom thiab hom bouncing gasket raws li kev ua haujlwm.
2, ceev faj hloov kho, ua haujlwm du.
3, yuav tsum sib npaug thiab symmetrically ntsia hlau ntsia liaj qhov rooj, yog hais tias tsim nyog, yuav tsum tau siv torque ciaj ntswj, preload yuav tsum tau raws li qhov yuav tsum tau, tsis loj los yog me me. Yuav tsum muaj qee qhov kev tshem tawm ntawm qhov sib koom ua ke ntawm flange thiab xov.
4, lub rooj sib dhos gasket yuav tsum tau ua kom zoo, lub zog tsis sib xws, gasket lap thiab siv ob lub gasket tsis raug tso cai.
5, zoo li qub sealing nto corrosion, kev puas tsuaj, kev ua haujlwm tsis zoo, yuav tsum tau kho, sib tsoo, tshuaj xyuas xim, ua kom zoo li qub sealing nto raws li qhov yuav tsum tau ua.
6. Thaum txhim kho lub gasket, yuav tsum tau them nyiaj rau kev tu, sealing nto yuav tsum yog kerosene ntshiab, thiab lub gasket yuav tsum tsis txhob poob rau hauv av.
Puas yog lub valve yuav tsum tau nruab bypass valve cov hauv paus ntsiab lus thiab Chaw? Qee lub sij hawm peb pom qee qhov loj li qub nyob rau hauv qee cov kav dej, thiab muaj ib txwm hla li qub ntsia. Vim li cas qhov no? Nws lub luag haujlwm tseem ceeb yog dab tsi? Raws li qhov xwm txheej twg nws yuav tsum tau teeb tsa? Dab tsi yog txoj kab uas hla ntawm bypass valve ntawm cov khoom siv? Qhov tseeb, lub bypass valve yog teem rau hauv lub raj xa dej, thiab nws lub luag haujlwm tuaj yeem muab faib ua ob lub ntsiab lus dav dav: ib qho yog ua lub luag haujlwm tiv thaiv (sib npaug siab ntawm ob qho kawg), lwm qhov yog qhov xwm txheej ceev!
Qee lub sij hawm peb pom qee qhov loj li qub nyob rau hauv qee cov kav dej, thiab muaj ib txwm hla li qub ntsia. Vim li cas qhov no? Nws lub luag haujlwm tseem ceeb yog dab tsi? Raws li qhov xwm txheej twg nws yuav tsum tau teeb tsa? Dab tsi yog txoj kab uas hla ntawm bypass valve ntawm cov khoom siv?
Qhov tseeb, lub bypass valve yog teem rau hauv lub raj xa dej, thiab nws lub luag haujlwm tuaj yeem muab faib ua ob lub ntsiab lus dav dav: ib qho yog ua lub luag haujlwm tiv thaiv (sib npaug siab ntawm ob qho kawg), lwm qhov yog qhov xwm txheej ceev!
Ua ntej, cov nyhuv tiv thaiv, kuj tuaj yeem hais tias yog ib qho kev tiv thaiv ntawm lub ntsiab valve, tiv thaiv lub valve ua ntej thiab tom qab lub siab sib txawv loj heev, thiab ua rau qhib tsis kam, lub valve tsis zoo qhib, tshwj xeeb tshaj yog nyob rau hauv qee qhov loj caliber los yog siab siab pipeline. Ua ntej qhib lub siab siab lub raj xa dej los ntawm lub bypass valve siab nyem, txhawm rau kom tsis txhob muaj kev kub siab dheev inrush, tsim ntawm kev cuam tshuam ntawm cov kav dej hauv qab lub valve. Los yog lub siab sib txawv ntawm ob qhov kawg ntawm lub valve yog qhov loj heev, qhov qhib lub zog loj heev, txhawm rau kom tsis txhob muaj kev puas tsuaj rau lub valve, hla lub siab nyem ua ntej qhib lub valve.
Qhov thib ob, lub luag haujlwm thaum muaj xwm txheej ceev, raws li cov kav dej xa mus rau kev siv, qhov txiaj ntsig loj tshaj plaws yog tias thaum lub ntsiab valve tsis ua haujlwm, lossis xav tau kev kho thiab kho dua tshiab, koj tuaj yeem qhib lub viav vias valve, thiab tsis cuam tshuam rau cov khoom qub.
Seb lub valve yuav tsum tau nruab los ntawm bypass valve tshwj xeeb yuav tsum tau thiab Chaw* rau siv)
2.5mpa qib, DN400 lossis siab dua; 4.0mpa qib, DN250 lossis siab dua; 6.4mpa qib, DN200 lossis siab dua; 10MPa qib, DN150 lossis siab dua;
DN100 ~ DN200 valve, bypass yeeb nkab thiab bypass valve rau DN20; DN250 ~ DN600 valve, bypass yeeb nkab thiab bypass valve rau DN25; Rau li qub tshaj DN600, lub bypass yeeb nkab thiab bypass valve yog DN40.
