Khoom zoo
Gas pipeline pob valve lub feature thiab qhov zoo
1. Lub siab ua haujlwm yog loj, thiab lub valve tuaj yeem qhib thiab kaw ruaj khov hauv qhov chaw ua haujlwm ntawm 0.4MPa.
2. Lub sijhawm qhib thiab kaw lub valve yog luv, thiab lub sijhawm qhib thiab kaw lub valve yog tsawg dua lossis sib npaug li 50s nyob rau hauv qhov txwv tsis pub ua haujlwm voltage ntawm 7.2V.
3. Tsis muaj qhov poob siab, thiab xoom-pressure poob qauv tsim nrog lub valve txoj kab uas hla sib npaug ntawm cov yeeb nkab txoj kab uas hla yog saws.
4. Lub sealing kev ua tau zoo ntawm lub kaw valve yog zoo, thiab lub foob yog ua los ntawm nitrile roj hmab nrog kub tsis kam (60 ℃) thiab tsis kub (-25 ℃).
5. Nrog kev txwv hloov, nws tuaj yeem txheeb xyuas qhov xwm txheej hauv txoj haujlwm ntawm qhov hloov valve.
6. Lub valve qhib-off ua haujlwm zoo, tsis muaj kev vibration thiab tsis muaj suab nrov.
7. Lub cev muaj zog thiab lub thawv iav tau kaw tag nrho, thiab qib kev tiv thaiv yog ≥ IP65, uas tiv thaiv kom tsis txhob kis tau tus mob nruab nrab nkag mus, thiab muaj kev ua haujlwm zoo tawg.
8. Lub cev valve yog ua los ntawm txhuas, uas tuaj yeem tiv taus 1.6MPa siab, tiv thaiv kev poob siab thiab kev co, thiab hloov mus rau qhov chaw nyuaj.
9. Qhov saum npoo ntawm lub valve lub cev yog anodized, uas zoo nkauj thiab huv si thiab muaj kev ua haujlwm zoo los tiv thaiv corrosion.
Kev qhia siv
1. Cov xaim liab thiab cov xaim dub yog cov xaim hluav taws xob, cov hlau dub txuas nrog rau qhov zoo electrode, thiab cov xaim liab txuas nrog qhov tsis zoo electrode qhib lub valve.
2. Kev xaiv nyob rau hauv txoj hauj lwm teeb liab tso zis kab: 2 kab dawb yog lub valve-qhib nyob rau hauv-txoj hauj lwm teeb liab kab, uas yog luv luv-circuited thaum lub valve nyob rau hauv qhov chaw;2 kab xiav yog lub valve-kaw nyob rau hauv txoj hauj lwm teeb liab kab, uas yog luv luv-circuited thaum lub valve nyob rau hauv qhov chaw;(Tom qab lub valve qhib los yog kaw, lub hwj huam mov feem ntau yog txuas ntxiv rau 5s los xyuas kom meej qhov ruaj khov ntawm cov teeb liab hauv txoj hauj lwm)
3. Lub thawv deceleration ntawm lub valve tuaj yeem tig 180 degrees tag nrho raws li qhov yooj yim ntawm tus neeg siv khoom los nruab lub thawv tswj, thiab lub valve tuaj yeem siv tau raws li kev sib hloov.
4. Siv tus qauv flange bolts los txuas li qub, kav dej, thiab flowmeters.Ua ntej kev teeb tsa, lub ntsej muag kawg ntawm lub flange yuav tsum tau ua tib zoo ntxuav kom tsis txhob muaj hlau slag, xeb, plua plav thiab lwm yam khoom ntse ntawm qhov kawg ntawm qhov chaw los ntawm khawb lub gasket thiab ua rau kom tawg.
5. Lub valve yuav tsum tau muab tso rau hauv lub raj xa dej lossis flowmeter nrog lub valve kaw.Nws yog nruj me ntsis txwv tsis pub siv nws nyob rau hauv lub xeev ntawm overpressure los yog roj to thiab mus ntes cov to nrog qhib hluav taws.
6. Cov tsos ntawm cov khoom no yog muab nrog ib daim ntawv teev npe.
