2 Hlau Kaw Valve Smart Gas Meter Fast-kaw Valve
Qhov chaw teeb tsa
Lub cev muaj zog valve tuaj yeem ntsia tau rau hauv lub ntsuas roj ntse.
Khoom zoo
Built-in ntsia hlau Tsav Valve qhov zoo
1. Tsis tshua muaj siab poob
2. Cov qauv ruaj khov Max siab tuaj yeem ncav cuag 150mbar
3. Cov duab me me, txhim kho yooj yim
4. Tus nqi qis
Kev qhia siv
1. Hom valve no muaj ob txoj hlua hlau los muab lub zog rau lub valve. Cov hlau liab txuas nrog lub zog zoo (lossis lub zog tsis zoo), thiab cov hlau dub txuas nrog lub zog tsis zoo (lossis lub zog zoo) kom qhib lub valve (tshwj xeeb, nws tuaj yeem tsim raws li cov neeg siv khoom xav tau).
2. Qhov tsawg kawg nkaus tsav voltage ntawm lub valve yuav tsum tsis txhob qis dua 3V. Yog tias qhov kev txwv tam sim no nyob rau hauv tus txheej txheem ntawm kev qhib thiab kaw lub valve, tus nqi txwv tam sim no yuav tsum tsis txhob qis dua 130mA.
3. Lub cev muaj zog valve qhib thiab kaw tuaj yeem raug txiav txim los ntawm kev kuaj xyuas cov xauv-rotor tam sim no hauv Circuit Court. Tus nqi xauv-rotor tam sim no tuaj yeem suav tau raws li kev ua haujlwm txiav tawm hluav taws xob ntawm kev tsim hluav taws xob, uas tsuas yog cuam tshuam rau qhov voltage thiab qhov tsis kam.
