Kev qhia siv
1. Cov hlau lead ntawm lub valve no muaj peb qhov tshwj xeeb: ob-xaim, plaub-xaim lossis rau-xaim. Cov hlau lead ntawm ob-xaim valve tsuas yog siv los ua lub valve nkaus xwb, cov hlau liab txuas nrog qhov zoo (lossis tsis zoo), thiab cov hlau dub txuas nrog qhov tsis zoo (lossis zoo) kom qhib lub valve (tshwj xeeb, nws tuaj yeem tsim raws li cov neeg siv khoom xav tau). Rau plaub-xaim thiab rau-xaim li qub, ob ntawm cov xov hlau (liab thiab dub) yog cov xaim hluav taws xob rau kev ua haujlwm ntawm lub valve, thiab ob lossis plaub ntawm cov xov hlau ntxiv yog cov xwm txheej hloov cov xov hlau, uas yog siv los ua cov teeb liab tso tawm xov hlau rau qhib thiab kaw txoj haujlwm.
2. Lub sijhawm siv fais fab: thaum qhib / kaw lub valve, tom qab cov cuab yeej kuaj pom tias lub valve nyob hauv qhov chaw, nws yuav tsum tau ncua 2000ms ua ntej nres lub zog, thiab tag nrho lub sijhawm ua haujlwm yog li 4.5s.
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.
4. Nws raug pom zoo tias qhov tsawg kawg nkaus DC voltage ntawm lub valve yuav tsum tsis pub tsawg tshaj 3V. Yog tias qhov kev txwv tam sim no yog nyob rau hauv lub valve txoj kev qhib thiab kaw, tus nqi txwv tam sim no yuav tsum tsis pub tsawg dua 120mA.
