Qhov sib txawv ntawm cov qauv tsim thiab kev ua haujlwm ua haujlwm
1. Npoo-Hom Rooj vag
- Lub rooj vag yog wedge-puab (ib leeg lossis ob chav wedges). Qhov ntsug txav ntawm lub valve qia compresses lub rooj vag tiv thaiv txoj kev nyob hauv lub rooj valine, ua tiav daim foob.
- Cov qauv raug suav nrog cov rooj vag sab-(haum xim kub) thiab cov rooj vag tsis haum (haum rau kev ntsuas siab).
- Lub foob yog pab los ntawm nruab nrab siab, nruj nrog ua kom muaj zog, ua rau nws haum rau cov kev mob siab (piv txwv li PN16-PN100).
2. Parallel GATE
- Lub rooj vag yog ob-phaj qauv nrog lub caij nplooj ntoos hlav lossis txhawb nqa cuab yeej hauv nruab nrab, yuam ob daim paib sib chwv nrog lub zog sab nraud.
- Muaj nyob rau hauv ib leeg-phaj (sealing los ntawm nruab nrab siab) thiab ob-phaj (sealing los ntawm caij nplooj ntoos hlav preload). Tom kawg yog qhov tsim nyog rau cov xov xwm qis lossis huv (piv txwv li, hauv qab pn10).
Kev Ua Tau Zoo thiab Thov Tso Cai
1. Kev sib khi
- Npoo-hom rooj vag muaj ntau lub rooj sib luag muaj ntau txoj kev sib khi tau zoo ntawm cov kev ntsuas siab, tab sis ib txwm to taub dej kub vim cov khoom tawg. Parallel Gates yog qhov yoog tau ntau dua rau cov khoom siv hluav taws xob tsawg thiab qhov ua tau.
- Raws li GB / T 12234-2019 tus qauv, theem kev sib tw vi (bubble qib vi (bubble cov rooj vag feem ntau yog chav kawm sib tw IV (dripe to taub).
2. Cov kua dej tsis kam
- Ob hom kev pab tiv thaiv qis thaum qhib kev tawm tsam ntau dua (xws li cov qauv sib dhos rau cov neeg hluav taws xob siab (xws li cov raj loj dua DN300).
3. Txij Nkawm
- Npoo Rooj Vag rooj vag valve txij nkawm yuav tsum sib tsoo cov chaw sib tsoo, uas siv sijhawm ntev. Parallel Rooj Vag qhov chaw tso cai rau kev hloov ceev ntawm rooj vag tuam tsev, txo cov nqi kho mob los ntawm 30%-cov ntaub ntawv: American Valve Koom Haum Luam Ntawv).
Cov Lus Taw Qhia Xaiv
1. Kev thov uas wedge rooj vag valve... 2. patalel gates tau txais cov ntaub ntawv uas muaj nrog cov khoom siv lossis hom dej phwj tuaj);
- Tsawg-siab, cov kav dej loj loj (piv txwv li, cov dej hauv nroog thiab tso dej thiab sib npaug nrog 500).
Cov kev paub ntxiv: Tshwj xeeb variant tsim
1. Tus "Giraste Elastic" ntawm lub rooj vag wedge them rau qhov kub thiab txias deformation thiab yog tsim rau qhov kub thiab txias los ntawm -196℃mus 550 degree.
2. Lub rooj vag "riam phom riam" ntawm lub rooj vag parallel tshwj xeeb yog tsim rau slurry media, nce kev txiav peev xwm los ntawm 40%.
