Regulating valve rau cov dej tseem ceeb bypass
| Hom | Regulating Valve |
| Qauv | T668Y-4500LB, T668Y-500, T668Y-630LB |
| Nominal Dia | DN 300-400 |
Nws yog siv rau cov dej loj hla cov yeeb nkab ntawm 1,000MW supercritical (ultra-supercritical) chav boiler rau kev tswj cov dej ntws.
- Lub valve yog hom qauv ncaj nraim, nruab nrab ntws kev taw qhia yog hom ntws thiab sealing nto ntawm lub rooj zaum valve yog nyob deb ntawm qhov kawg kauj ruam flash evaporation tsam kom lav kev pabcuam lub neej.
- Lub cev lub cev thiab lub kaus mom tau txais cov qauv hlau forged nrog lub zog siab kom ua tau raws li lub zog xav tau nyob rau hauv qhov kub thiab txias.
- Nws txais yuav tshem tau lub rooj zaum valve thiab lub rooj zaum valve muaj Stellite No. 6 alloy build-up welding ntawm nws qhov sealing nto.
- Lub valve disc txais cov qauv sib npaug thiab sealing nto undergoes siab zaus quenching; Cov kab noj hniav sab sauv thiab sab qis ntawm lub valve disc paub qhov sib npaug ntawm qhov sib npaug los ntawm qhov sib txuas. Hauv qhov no, lub valve tuaj yeem raug kaw los ntawm lub tshuab tsav nrog lub zog qis dua.
- Throttle tivthaiv ntawm lub valve tub ntxhais yog tsim los txais yuav 6-txheej txheej npog 5-kauj ruam siab txo cov qauv kom tawg ib leeg strand kua nrog siab zog mus rau hauv ntau strand kua nrog tsawg zog kom txo tau ceev thiab suab nrov. Kev txo qis ib ntus yog pom tau los ntawm aperture dislocation kom tshem tawm cavitation. Cov kauj ruam kawg lub tes tsho ua kom cov kua dej tawm mus raws tangent kab kev taw qhia thiab lub ntsej muag sab hauv kab noj hniav ntawm lub cev valve indirectly kom txo tau scouring rau lub valve lub cev.
- Nruab nrab flange sealing adopts dual-sealing qauv ntawm yoj hniav sib xyaw gasket thiab elastic zog cia nplhaib, ua sealing ntau txhim khu kev qha.
- Raws li kev ua haujlwm ntawm cov dej ntws me me thiab qhov sib txawv loj, ntau lub tes tsho throttle tau txais yuav thiab cov kauj ruam los ntawm kev txo qis yog pom tau los ntawm dislocation kev npaj ntawm aperture nrog txoj kab uas tsis sib npaug los tswj qhov nruab nrab khiav ceev nruj me ntsis thiab txo qhov cuam tshuam ntawm cavitation thiab flash evaporation ntawm valve. Raws li kev ua haujlwm ntawm cov dej ntws loj thiab qhov sib txawv me me, lub qhov rais ib-kauj ruam yog siv los txo qis kom muaj peev xwm txaus ntawm lub valve.
- Cov yam ntxwv ntawm kev tswj hwm yog txhim kho qhov sib npaug feem pua, muaj peev xwm tswj tau qhov nruab nrab ntws kom raug kom ua tiav cov kev cai zoo.
- Lub valve tuaj yeem nruab nrog kev xaiv hluav taws xob lossis pneumatic mechanism kom paub qhov ceev ceev qhib thiab kaw thiab peb-tiv thaiv.
