Ivalve yokuqhawula ivacuum yePV48
Uhlobo: ivelufa eqhekezayo yamandla enyukliya
Umzekelo: ZKPHF41F-150 150Lb, ZKPHF21F-300 300Lb
Ubungakanani bomthamo: DN 20-50
Imveliso isetyenziselwa iyunithi ye-AP1000 njengesixhobo sokufunxa uxinzelelo olubi ukuthintela uxinzelelo oluphantsi olugqithisileyo ekonakaliseni isixhobo.
I-1.Ngohlobo lwe-spring vacuum decompression, i-valve yokuqhawula i-vacuum ibonisa uxinzelelo olulula oluqhubekayo kunye nokulungiswa kunye nofakelo olufanelekileyo. Ivalve iyilwe ngokwenqanaba loxinzelelo kwaye uxinzelelo lwayo loyilo lukhulu kunoxinzelelo oluphezulu lokusebenza phantsi kobushushu bendawo yokusebenza. Ivalve core ivula kwaye ivale indawo yevalve kunye ne-O-type yeringi yokutywina ifakwe kwigroove yombindi wevalve ukwenza indawo yokutywina yombindi wevalve. Xa ivalve itywina, i-O-uhlobo lokutywina ikhonkco lokutywina umphezulu wesihlalo sevalve; xa ivalve itsiba kwaye ikhuphela, i-O-type itywina ishiya umphezulu wokutywina wesihlalo sevalve. Xa i-valve core ivuthela ngasemva, intwasahlobo iyolula kwaye indawo yokuvula kunye nokuvala iya phezulu kunye nomngxuma okhokelayo wesihlalo sevalve; xa undoqo wevalve uvula, i-spring compresses kunye nenxalenye yokuvula kunye nokuvala yehla kunye nomngxuma okhokelela kwisitulo sevalve.
2.I-vacuum yokuqhawula i-valve, i-valve ezenzekelayo, ayifuni i-drive eyongezelelweyo xa ifakwe ekusebenzeni. Kwimo yesiqhelo yokusebenza, amandla adibeneyo entwasahlobo naphakathi asetyenziswa kwidiskhi yevalvu icinezela idiski yevalvu ukuya kwisitulo sevalvu ukwenza umphezulu wokutywina uncamathele kwaye utywine; xa uxinzelelo oluphakathi luhla lusiya kwixabiso elikhankanyiweyo levacuum (oko kukuthi uxinzelelo olubi ukuya kuxinzelelo lokumisela), intwasahlobo iyaxinzelelwa, idiskhi yevalve ishiya isihlalo sevalve, kungena umoya wangaphandle kunye noxinzelelo lwenkqubo yonyuso; xa uxinzelelo lwenkqubo lunyukela kwixabiso lokusebenza, intwasahlobo itsalela idiski yevalvu ukuya kwisihlalo sevalve kwaye umphezulu wokutywina uncamathele kwakhona ukuze ubuyele kwimeko yokusebenza eqhelekileyo.
