Nco tseg: Qhov ntsuas kub thiab nruab nrab yog nyob ntawm cov khoom sib txawv ntawm lub rooj zaum valve, lub cev, stems thiab discs, saib lub rooj 1 thiab rooj 2:
Khoom Txheem
Cov khoom ua tau raws li BS EN 593: 1984 "INDUSTRIAL VALVES-METALLIC BUTTERFLY VALVES" tus qauv yuav tsum tau ua.
Flange drilled thiab conforms rauBS EN 1092-1,BS EN 1092-2,SIB 4504:Nqe 3.3:1989 "FLANGES thiab lawv cov pob qij txha-circular Flanges rau cov kav dej,VALVES, FITTINGS thiab Accessories, PN tsim"Standard xav tau.
Kev tuav haujlwm hom
Tes lever
Iav lub thawv
Khoom nta
Me me thiab lub teeb rau ntau txoj haujlwm installation, yooj yim rau disassembled thiab khaws cia
Cov qauv yog yooj yim, compact, thiab tuaj yeem qhib-kaw los ntawm 90 degree sai.
Tsawg torque ruaj khov rau kev txuag nqi zog
Zero leakage
Ntau yam khoom siv muaj rau kev siv ntau yam ntawm nruab nrab
Kev tswj hwm kev ua tau zoo vim qhov ncaj-lined flow nkhaus
Lub neej ntev foob mus txog kaum tawm txhiab zaus rau qhib thiab kaw
VII. Txoj Cai Kev Ua Haujlwm
Qhov npauj npaim valve no yog tsim los ntawm lub cev lub cev, qia, disc thiab lub rooj zaum, lubrication bushing, tus pin (tuaj yeem tsim tus pin-tsawg), phau ntawv ua haujlwm (kov lossis lub thawv iav). Kev tswj ntawm nruab nrab ntws thiab qhib thiab kaw yog tsav thiab ua tiav los ntawm kev tig lub qia thiab lub disc.
Rau kev ua haujlwm ntawm tes, nias lub khawm thiab tig lub moos 90 degrees kom kaw lub disc thiab tom qab ntawd tso lub zog. Kev tswj hwm kev tswj hwm thiab qhov nruab nrab ntws yuav ua tiav los ntawm kev nrhiav txoj haujlwm qhia (muaj 10 qhov chaw nyob nruab nrab ntawm 0 degree ~ 90 degree)
Rau kev ua haujlwm ntawm lub thawv iav, tig cov iav iav kom qhib thiab kaw lub disc kom ua tiav cov kev cai nruab nrab thiab ntws. Lub valve yuav raug kaw los ntawm kev sib hloov clockwise
