Electric wedge rooj vag valve: kev ua haujlwm, yam ntxwv, thiab kev siv
Hluav taws xob lub rooj vag valve yog ib qho kev tawm suab valve uas sib phim nrog Z-hom multi tig actuator thiab tuaj nyob rau hauv ob qho tib si hloov thiab ntse hom. Hom valve no yooj yim rau kev khiav lag luam thiab yog qhov feem ntau qhib thiab kaw valve, uas yog siv lub nce thiab nqis ntawm lub rooj vag mus txuas thiab kaw cov kua nruab nrab hauv cov kav dej. Nws muaj ntau yam kev siv, suav nrog kev lag luam xws li hluav taws xob, metallurgy, roj av, tshuaj lom neeg, papermaking, thiab dej phwj tuaj kho.
Cov khoom nta ntawm hluav taws xob wedge rooj vag li qub feem ntau suav nrog cov ntsiab lus hauv qab no:
1. Cov kua dej tsis kam yog me me, thiab qhov sealing nto tsis tshua muaj kev cuam tshuam rau kev yaig thiab yaig los ntawm qhov nruab nrab.
2. Nws yog ib qho yooj yim qhib, muaj kev sib khi zoo, tsis muaj kev txwv nruab nrab ntws, tsis cuam tshuam kev khiav, thiab tsis txo qhov siab.
3. Nws muaj cov duab yooj yim, cov txheej txheem tsim khoom zoo, thiab kev siv ntau yam.
Cov qauv kev ua haujlwm rau lub qhov rooj hluav taws xob muaj xws li GB / T13927, JB / T 79, GB / T9113, GB / T 12224, GB / T12234, GB / T12221, HG / T20592, EN1092, thiab JB / T9092.
Nyob rau hauv cov nqe lus ntawm lub ntsiab kev ua tau zoo specifications, hluav taws xob wedge rooj vag li qub yog haum rau ntau yam xov xwm thiab kub. Piv txwv li, carbon steel (C-type) yog haum rau cov dej, chav, thiab roj cov khoom, nrog rau ib tug haum kub ntawm ≤ 425 ℃; Chromium npib tsib xee steel (P-hom) yog haum rau nitric acid, nrog ib tug haum kub ntawm ≤ 200 ℃; Chromium nickel molybdenum steel (R-type) yog tsim rau acetic acid, nrog rau qhov kub thiab txias ntawm ≤ 200 ℃; Chromium molybdenum steel (Hom I) yog tsim rau cov khoom siv dej, chav dej, thiab roj, nrog rau qhov kub thiab txias ntawm ≤ 550 ℃.
Cov ntaub ntawv tseem ceeb ntawm lub rooj vag hluav taws xob muaj xws li lub cev lub cev / npog, lub rooj vag / lub rooj, valve qia txiv ntoo, tes tuav, thiab lub qia valve. Kev xaiv cov khoom ntawm cov khoom no feem ntau yog txiav txim siab raws li qhov chaw ua haujlwm thiab cov khoom nruab nrab ntawm lub valve kom ntseeg tau tias kev ua haujlwm thiab lub neej ntev ntawm lub valve.
Zuag qhia tag nrho, hluav taws xob wedge rooj vag li qub yog qhov ua tau zoo, txhim khu kev qha, thiab kev lag luam zoo li qub tau siv dav hauv ntau yam kev lag luam.
