I-valve yokuqhekeza i-PV48
Uhlobo: amandla enyukliya yokuqhekeza ivelufa
Umzekelo: ZKPHF41F-150 150Lb, ZKPHF21F-300 300Lb
Ububanzi obuchongiweyo: DN 20-50
Imveliso isetyenziselwa iyunithi ye-AP1000 njengezixhobo ezingafunekiyo zoxinzelelo lokuthintela uxinzelelo lwayo olusezantsi kakhulu ekonakaliseni izixhobo.
1.Ngohlobo lwentwasahlobo yohlobo lwe-vacuum decompression, i-valve yokuqhekeza inkunkuma inexinzelelo olulula kunye nokulungiswa kunye nokufakelwa okufanelekileyo. Ivalveyile yenzelwe ngokwenqanaba loxinzelelo kwaye uyilo lwayo luxinzelelekile kunoxinzelelo oluphezulu lokusebenza phantsi kobushushu bendawo yokusebenza. Isiseko sevalve siyavula kwaye sivale indawo yevalve kunye ne-O-type seal ring efakwe kumjelo wesiseko sevalvu ukwenza uphawu lokutywinwa kwesiseko sevalve. Xa ivalve itywina, O-uhlobo uphawu isangqa abafowunelwa uphawu uphawu isihlalo ivelufa; xa i-valve ixhuma kwaye ikhupha, i-O-type ring ring ishiya uphawu lomhlaba wesitulo se-valve. Xa isiseko sevalve sibetha umva, intwasahlobo yolula kwaye indawo yokuvula kunye neyokuvala inyuka ecaleni komngxunya okhokelayo wesihlalo sevalve; xa kuvulwa isiseko sevalve, uxinzelelo lwentwasahlobo kunye nokuvula kunye nokuvala indawo iyehla ecaleni komngxunya okhokelayo wesihlalo sevalve.
2.Ivalve yokuqhekeza inkunkuma, ivelufa ezenzekelayo, ayifuni kuqhuba xa isenziwa. Kwimeko yesiqhelo yokusebenza, amandla adibeneyo entwasahlobo kunye naphakathi okunyanzeliswa kwidiski yevalve icinezela idiski yevalve isiya kwisihlalo sevalve ukwenza ukutywina komphezulu kunamathele kunye nokutywina; xa uxinzelelo oluphakathi luye kwixabiso elichaziweyo le-vacuum (okt uxinzelelo olubi ukuya kuseto loxinzelelo), intwasahlobo icinezelwe, idiski yevalve ishiya isihlalo sevalve, umoya wangaphandle ungena kwaye uxinzelelo lwenkqubo lukhula; xa uxinzelelo lwenkqubo lonyuka ukuya kwixabiso lokusebenza, intwasahlobo itsala idiski yevalve isiya kwisihlalo sevalve kwaye itywina umphezulu wokubamba kwakhona ukubuyela kwimeko yesiqhelo yokusebenza.
