Mfundo yogwira ntchito ya valve yothandizira

Valavu yothandizira ndi mtundu wa valavu yowongolera mafuta, yomwe imagwira ntchito ngati kusefukira kosalekeza, kuwongolera kupanikizika, kubwezeretsa dongosolo komanso chitetezo chachitetezo pazida zamagetsi.

Mfundo ya valve yothandizira: Mu ndondomeko yoyendetsera kayendedwe ka pampu, pampu yowonjezera imapereka kuthamanga kosalekeza, ndipo pamene kupanikizika kwa dongosolo kumachepetsedwa, kufunikira kwa kutuluka kudzachepetsedwa.Panthawiyi, valavu yothandizira imatsegula valavu yowongolera ndi kuchepetsa kuti madzi ayambe kusefukira ku thanki ndikuwonetsetsa kuti valavu yolowera imalowa.

Mu dongosolo lokhazikika la kupopera kwapampu, pampu yokhazikika imapereka kuyenda kosalekeza.Pamene kupanikizika kwa dongosolo kumachepetsedwa, kufunikira kothamanga kudzachepetsedwa.Panthawiyi, valve yothandizira imatsegulidwa, kotero kuti kutuluka kwakukulu kumabwereranso ku tank pressure regulator ndi kuchepetsa kupanikizika kwa valve, kuonetsetsa kuti mpweya wotsekemera wa valve, ndiye kuti, kuthamanga kwa mpweya kumakhala kosalekeza. nthawi zambiri amatsegulidwa ndi kusinthasintha kwamphamvu).

Kusiyana pakati pa valavu yothandizira ndi valavu yochepetsera kuthamanga

Valve yothandizira ndikupewa kuthamangitsa dongosolo ndikuwonetsetsa chitetezo.Valavu yochepetsera kuthamanga ndikuwonjezera kupanikizika kwa dongosolo pansi pazifukwa zowonetsetsa kuti dongosolo silikusowa gawo.

1, valavu yochepetsera mphamvu imagwiritsidwa ntchito makamaka kuchepetsa kupanikizika kwa mzere wa nthambi ya kayendedwe ka mafuta, kotero kuti kupanikizika kwa nthambi kumakhala kochepa komanso kosasunthika kusiyana ndi kuthamanga kwakukulu kwa mafuta, pamtundu wa kuyika, valavu yochepetsera mphamvu. inazimitsanso ngati valve yothandizira.Ndipo ndi kuchepa kwa kupanikizika kwa dongosolo, pamene kupanikizika kwa valavu yochepetsera kuthamanga kumafika, valve yochepetsera kuthamanga imatsegulidwa, ndipo gawo lina la mafuta lidzabwerera ku thanki (panthawiyi, pali kupanikizika kwina kwa chitsulo chachitsulo). mafuta kubwerera ku thanki, kutentha kwa madzi kwa thanki kudzakwera), kuthamanga kwa hydraulic kwa nthambi iyi sikudzauka.Imagwira ntchito yochepetsera kupanikizika ndikukhazikika panjira iyi!Valve yothandizira ndi yosiyana, ndipo imayikidwa pamtunda wa mpope kuti zitsimikizire kuti kupanikizika konse kwa dongosololi kumakhala kokhazikika komanso sikupitirira.Chifukwa chake, ali ndi gawo lachitetezo, kuwongolera kupanikizika, kuwongolera kukakamiza ndi zina zotero!

2, valavu yothandizira nthawi zambiri imakhala yofanana mumsewu wamapiri kuti igwire ntchito yolamulira kupanikizika, kuwongolera kupanikizika ndi kuchepetsa kupanikizika, ndipo valavu yochepetsera mphamvu nthawi zambiri imakhala yotsatizana pamsewu kuti igwire ntchito yochepetsera kupanikizika ndi kuchepetsa mphamvu. njira yotetezera kuthamanga!

3, valavu mpumulo nthawi zambiri kutsekedwa, komanso pamene dongosolo overpressure kanthu;Valavu yochepetsera kuthamanga ndi yotseguka ndipo imadetsa nkhawa kudzera munjira yopapatiza.

4, ntchito ya valve yothandizira ndikuwongolera kuthamanga, kusefukira, chitetezo chokwanira.Valavu yochepetsera mphamvu imachepetsa kupanikizika, ndipo kupanikizika kwa gawo lina la dongosolo la mafuta kumachepetsedwa.Zogwiritsa ntchito zosiyanasiyana.Choncho, sichingasinthidwe.
