2 Hlau Ceev Kaw Hluav Taws Xob Valve Hauv Tsev Gas Meters

Qauv TSIS MUAJ: RKF-2-2W

Lus piav qhia luv luv:

RKF-2 yog ib qho tshwj xeeb valve ntsia rau ntawm lub ntsuas roj los tswj kev tawm ntawm cov roj. Nrog rau kev tsim tshwj xeeb ntawm ratchet mechanism, tsis muaj teeb meem nrog lub cev muaj zog thaiv thaum lub sijhawm qhib thiab kaw ntawm lub valve. Qhov kev tsim no tiv thaiv cov iav los ntawm kev puas tsuaj los yog ntes nyob rau hauv siab. Muaj lub caij nplooj ntoos hlav hauv lub valve, uas absorbs lub zog thaum lub valve qhib, yog li lub zog yuav tsum tau kaw lub valve yog qhov tsawg kawg nkaus, thiab lub valve tuaj yeem kaw tam sim ntawd.

Qhov zoo

Built-in lub cev muaj zog pob valve qhov zoo
1. Ceev ceev
2.Stable qauv Max siab tuaj yeem ncav cuag 200mbar
3. Kaw nrog lub zog qis
4.Slexible customized kev daws teeb meem: Koj tuaj yeem xaiv qhov hloov pauv ntawm 2 xov hlau mus rau 6 xov hlau.
5.Tsis muaj lub cev muaj zog thaiv

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-wir e 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. Cov khoom siv fais fab: DC2.5V rau 2s thaum qhib valve. Thaum lub valve kaw, lub sijhawm siv hluav taws xob yuav tsum ntev dua 300ms, thiab lub valve tuaj yeem qhib thiab kaw tau zoo.
3. Qhov tsawg kawg nkaus tsav voltage ntawm lub valve yuav tsum tsis txhob qis dua 2.5V. 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 100mA.
4. Nws raug pom zoo tias qhov tsawg kawg nkaus DC voltage ntawm lub valve yuav tsum tsis pub tsawg tshaj 2.5V. Yog tias qhov kev txwv tam sim no nyob rau hauv lub valve txoj kev qhib thiab kaw, tus nqi txwv tam sim no yuav tsum tsis pub tsawg dua 60mA.
