Nyob rau lub Yim Hli 2018, CONVISTA tau ua tiav kev tsim lub Parallel Slide Gate Valves rau cov kav dej siab thiab nruab nrab ntawm 600 txog 1,000MW supercritical (ultra-supercritical) chav tsev chav turbine.Qhov kom zoo dua ntawm cov khoom raws li hauv qab no:
1.It adopts siab self-sealing qauv, nrog welded kev twb kev txuas ntawm ob hnub.
2.Nws siv hluav taws xob bypass valve ntawm qhov nkag thiab qhov hluav taws xob rau ntsuas qhov sib txawv ntawm qhov nkag thiab qhov hluav taws xob.
3. Nws kaw mechanism adopts parallel dual-flashboard qauv. Valve sealing yog los ntawm nruab nrab siab es tsis txhob los ntawm wedge mechanical acting force los tiv thaiv lub valve los ntawm kev tsim txom txaus ntshai thaum nws qhib thiab kaw.
4. Nrog cobalt-based rigid alloy build-up welding, lub ntsej muag sealing nta kub tsis kam, corrosion kuj, abrasion kuj, ntev kev pab cuam lub neej thiab lwm yam ntxwv.
5. Kev tiv thaiv corrosion thiab nitrogenization kev kho mob, lub valve qia nto nta zoo corrosion kuj, abrasion kuj thiab txhim khu kev qha khoom ntim thawv sealing.
6. Nws tuaj yeem phim nrog ntau yam khoom siv hluav taws xob hauv tsev thiab txawv teb chaws kom ua tau raws li DCS tswj cov cai thiab paub txog kev ua haujlwm hauv chaw taws teeb thiab hauv zos.
7. Nws yuav tsum qhib tag nrho lossis kaw thaum lub sijhawm ua haujlwm. Nws yuav tsum tsis txhob siv raws li lub regulating valve.
