Kodi ESDV ndi chiyani

An Emergency Shut Down Valve(ESDV) ndi gawo lofunikira kwambiri pamachitidwe osiyanasiyana amakampani, makamaka m'gawo lamafuta ndi gasi, komwe chitetezo ndi magwiridwe antchito ndizofunikira kwambiri.Mtengo wa ESDVadapangidwa kuti aletse msanga kutuluka kwa madzi kapena mpweya pakagwa mwadzidzidzi, potero kupewa zoopsa zomwe zingachitike monga kutayikira, kuphulika, kapena kulephera kwina koopsa.

Mawu akuti "SDV" amatanthauza Shut Down Valve, yomwe imaphatikizapo gulu lalikulu la mavavu omwe amagwiritsidwa ntchito kuletsa kutuluka kwa zinthu m'mapaipi. Ngakhale ma ESDV onse ndi ma SDV, si ma SDV onse omwe amagawidwa ngati ma ESDV. Kusiyanitsa kuli mu ntchito yeniyeni komanso kufulumira kwa yankho lomwe likufunika. Ma ESDV nthawi zambiri amayendetsedwa ndi chitetezo kapena pamanja ndi ogwira ntchito pakagwa mwadzidzidzi, kuwonetsetsa kuyankha mwachangu kuti achepetse zoopsa.

Ma ESDV ali ndi zinthu zosiyanasiyana zomwe zimawonjezera kudalirika kwawo komanso magwiridwe antchito. Izi zingaphatikizepo njira zolephera, zomwe zimatsimikizira kuti valavu imatseka pakagwa mphamvu, ndi mphamvu zakutali, zomwe zimalola ogwira ntchito kuyendetsa valve kutali. Mapangidwe ndi zida zomwe zimagwiritsidwa ntchito mu ESDVs ndizofunikanso, chifukwa zimayenera kupirira zovuta komanso malo owononga omwe amapezeka nthawi zambiri m'mafakitale.

Mwachidule, Emergency Shut Down Valve (ESDV) imagwira ntchito yofunika kwambiri pakusunga chitetezo pantchito zama mafakitale. Pomvetsetsa kuti ESDV ndi chiyani komanso momwe imagwirira ntchito, ogwira ntchito amatha kuzindikira kufunika kwake pokonzekera mwadzidzidzi ndi njira zothetsera mavuto. Kukhazikitsa bwino kwa ma ESDV sikungoteteza ogwira ntchito ndi zida komanso kumathandizira kuti magwiridwe antchito azigawo za mafakitale azikhala ofunikira kwambiri m'malo omwe ali pachiwopsezo chachikulu.
