I-Valve Yokuhlola I-Running engasebenzi

Izici

Kuyivalvu ekhethekile yokuvala ngokushesha yokuvikela iyunithi yejeneretha ye-steam turbine.Iklanyelwe ukuvimbela ukucindezela ku-turbine yesitimu ekuncipheni ngokuzumayo lapho iyunithi ye-steam turbine ilahlekelwa umthwalo ngokuzumayo, kanye nesitimu esisepayipini lokukhipha kanye nama-heaters ahlukahlukene ukuthi angagelezi abuyele enjini yesitimu, okubangela ama-blade eturbine yesitimu azungezisayo. isivinini esikhulu sokuphenduka okungaphezulu kuka-3000 ngomzuzu ukuze sigijime ngokuzumayo sibuyele emuva, ngaleyo ndlela kubangele ingozi enyanyekayo yokuthi izindwani ze-steam turbine ziphukile futhi kulimale ijeneretha ye-steam turbine, Futhi kuvimbele ingozi yesando samanzi ebangelwa ukuvuza kwechibi lepayipi le-heater. uhlelo namanzi angena ku-turbine esuka epayipini lokukhipha.Uma kunezimo ezingenhla, i-valve ingavalwa ngokushesha phakathi kwama-0.5s.

Izicelo:

1. I-pneumatic stop callback iwukuphusha ipiston emoyeni ibe bomvu ngomoya ocindezelwe, ipiston iphushe imfoloko ye-shift, bese i-shift fork ishayela i-rocker shaft ukuthi ijikelezise ukuze uvule ivalvu.Ivalvu ivalwa ngokuphusha i-spring grid piston emuva ukuze inqamule ukutholakala komoya ngokulungiswa kwe-electromagnetic.

2. Indawo evalekayo ye-net candy kanye ne-ridge base yenziwe ngezinto zakamuva ezivelela phezulu, ezinokumelana nokugqokwa okuqinile nokumelana nokuklwebheka.

3. Ukusebenza okuphezulu kokupakisha okusha, ukubeka uphawu okuthembekile, ukusebenza okulula nokuvumelana nezimo.

I-Nickel Base Alloy High Pressure & Temperature Check Valve

Izici:

Ukuze kuqinisekiswe izidingo eziphakeme zokuqina, ukuthembeka nokuphepha komnyango wesikrini, umzimba we-valve wenziwe nge-nickel base alloy uwonke, noma wakhiwe futhi washiselwa.Indawo yokuvala yomnyango we-valve ishiselwe nge-alloy eqinile ukuze kuthuthukiswe ukumelana nokugqokwa kwayo nokumelana nokuklwebheka, futhi kuthuthukise impilo yesevisi yendawo yokuvala.Igumbi eliphakathi lomnyango obanzi lithatha isakhiwo sokuzivala, esivumela ukuvala uphawu lokucindezela okukhulu.Lapho ingcindezi iphezulu, kungcono ukuvala uphawu.
