Ivalve yebhola edadayo ye-TA2 yenziwa kusetyenziswa umatshini we-TA2. I-TA2 yi-titanium ecocekileyo yoshishino. Ngokomxholo wokungcola owahlukileyo, wahlulwe ngokwamanqanaba amathathu: TA1, TA2, kunye ne-TA3. Izinto zokungacoceki kwe-interstitial kwezi zintathu ze-titanium ezisulungekileyo zonyuka ngokuthe ngcembe, ngoko ke amandla abo omatshini kunye nobulukhuni babo buyanda ngokuthe ngcembe, kodwa iplastiki kunye nokuqina kwabo kuncipha ngokufanelekileyo. I-titanium ecocekileyo esetyenziswa ngokuqhelekileyo kwishishini yi-TA2, ngenxa yokunganyangeki kwayo okuphakathi kunye neempawu zoomatshini ezibanzi. I-TA3 ingasetyenziswa xa iimfuno eziphezulu zibekwe ekuxhathiseni ukunxiba kunye namandla.

Ivalve yebhola edadayo eyenziwe ngentsimbi ye-super duplex stainless (S32750) ukusetyenzwa. Izinto eziphathekayo ze-S32750 yintsimbi yensimbi engenasici enokumelana nokugqwesa okugqwesileyo kunye namandla. Yeyeferritic austenitic steel stainless steel, equlethe ukuya kwi-25% yechromium, i-7% ye-nickel, i-4% ye-molybdenum, kunye ne-0.25% ye-nitrogen.

Izihluzi zika-Y (izihluzi ezimilise u-Y) sisixhobo esiyimfuneko sokucoca kwiinkqubo zemibhobho yokuhambisa imidiya. Ngokuqhelekileyo zifakwe kwi-inlet ye-inlet yokunciphisa i-valve, i-valve yokunciphisa, i-valve yezinga lamanzi rhoqo, okanye ezinye izixhobo zokususa ukungcola kwi-medium kunye nokukhusela ukusetyenziswa okuqhelekileyo kwezixhobo kunye nezixhobo.

Ivalve ye-titanium eyenziwe ngomgunyathi yivalve eyenziwe ngemathiriyeli yesinyithi ye-titanium engumgunyathi (B381 Gr. F-2). Iifilimu ze-Titanium oxide zinozinzo olulungileyo kunye nobuchule bokuzenzela kwindawo enomhlwa kakhulu, ezinokumelana nokubola okuqinileyo phantsi kweemeko ezahlukeneyo zokusebenza eziqatha.

Icandelo lokuvula kunye nokuvala i-valve yesango yentsimbi ekhandiweyo yiplati yesango, kwaye isalathiso sokuhamba kweplate yesango i-perpendicular ukuya kwi-fluid. Iivalve zesango zentsimbi ezibunjiweyo zinokuvuleka ngokupheleleyo kwaye zivalwe ngokupheleleyo, kwaye azikwazi ukulungiswa okanye ukunyanyiswa. Ipleyiti yesango yevalve yesango yentsimbi ekhandiweyo ineendawo ezimbini zokutywina, kwaye eyona ndlela isetyenziswa ngokuqhelekileyo yevalve yesango kukuba iindawo ezimbini zokutywina zenza imilo ye-wedge, kwaye i-angle ye-wedge iyahluka kunye neeparamitha zevalve.

Umsesane wokutywina wevalve yebhabhathane eqinileyo etywiniweyo emithathu ineendlela ezintathu: inqanaba elihlukeneyo, elastiki, kunye nentsimbi yonke. Konke ukutywinwa okuqinileyo kwesinyithi kwahlukile kumanqanaba amaninzi otywino oluqinileyo kunye nokutywinwa okuqinileyo okulastiki. Zonke iivalve zebhabhathane eziqinileyo ezitywiniweyo zilungele iimeko zobushushu obuphezulu.

Ngexesha lokusebenza kwe-trunnion efakwe kwi-valve yebhola, onke amandla aveliswa ngoxinzelelo lwe-fluid kwibhola adluliselwa kwi-bearing, engayi kubangela ukuba ibhola ihambe ukuya kwisihlalo sevalve, kwaye isihlalo sevalve asiyi kuthwala uxinzelelo olugqithisileyo. Iivalve zebhola ezilungisiweyo zinetorque ephantsi, i-deformation encinci yesihlalo, ukusebenza kokutywinwa okuzinzileyo, kunye nobomi benkonzo ende. Zombini ii-valve zebhola ezinobubanzi obukhulu kunye noxinzelelo oluphezulu ziya kuyilwa njengezakhiwo ezizinzileyo.

I-Trunnion efakwe kwi-valve yebhola yentsimbi eyenziweyo yenziwe ngezinto ezibunjiweyo ezinoxinano oluphezulu kakhulu kunolo lokuphosa, olufanelekileyo kwiimeko zoxinzelelo oluphezulu. Ivalve yentsimbi ekhutshiweyo yoxinzelelo oluphezulu yahlula umzimba wevalve ube ngamacandelo amathathu ecaleni kwecandelo elithe gqolo kwiaxis yeshaneli yevalve kwizitulo ezibini zevalve. Ivalve yonke i-symmetrical malunga nombindi we-axis yesikhondo sevalve. Ivalve yebhola esisigxina isetyenziswa ikakhulu kwimibhobho ukusika, ukusasaza, kunye nokutshintsha indlela yokuhamba okuphakathi.

I-F904L super austenitic steel stainless yi-carbon ephantsi, i-nickel ephezulu, i-molybdenum austenitic stainless acid resistant steel kunye ne-activation activation yokuguquguquka okugqwesileyo kunye nokumelana nokugqwesa okugqwesileyo. Inokumelana ne-corrosion elungileyo kwiiasidi ezingezizo i-oxidizing ezifana ne-asidi ye-sulfuric, i-asidi ye-formic, kunye ne-asidi ye-phosphoric, kwaye inokumelana kakuhle ne-pitting corrosion kwi-ion ye-chloride engathathi hlangothi equlethe imidiya. Kwangaxeshanye, inokumelana kakuhle nokubola kwemingxuma kunye noxinzelelo lwe-corrosion.

Ivalve yohlobo lomkhono weplagi ibandakanya umzimba weplagi, umkhono, i-clamping nut, kunye nesiqu sevalve. Umzimba weplagi ngumzimba ophambili wevalve, kunye nomjelo ofanayo ngaphakathi kumbhobho. Umkhono ubekwe phezulu kumzimba weplagi kwaye wenze itywina ngomzimba weplagi. I-nut yoxinzelelo ixhunyiwe kumzimba weplagi ngentambo ukulungisa umkhono. Isiqu sevalve sidlula kwi-sleeve kwaye siqhagamshelwe kwivili lesandla okanye kwisixhobo sombane phezulu ukuze kusetyenziswe ivalve.

Ivalve yeglowubhu, ekwabizwa ngokuba yivalve yokuvala, yivalve yokutywina ngenkani. Ngoko ke, xa i-valve ivaliwe, uxinzelelo kufuneka lusetyenziswe kwi-disc ye-valve ukunyanzela indawo yokutywina ukuba ingavuzi. Xa i-medium ingena kwi-valve esuka ngaphantsi kwe-disc ye-valve, ukuchasana okufuneka kunqotshwe ngamandla okusebenza kukunyanzeliswa kwe-friction phakathi kwe-valve stem kunye nokupakisha kunye ne-thrust eyenziwa ngoxinzelelo lwe-medium. Amandla okuvala ivalve mkhulu kunamandla okuyivula, ngoko ke ububanzi besiqu sevalve kufuneka bube bukhulu, kungenjalo kuya kubangela ukuba isiqu sevalve sigobe.

I-BOLON igxile ekuveliseni iivalvu ezikhethekileyo, ngakumbi iivalve zesango le-zirconium. I-Zirconium 702C i-valve yesango i-zirconium alloy yimathiriyeli ye-alloy esebenza kakhulu eyenziwe ngokukodwa zirconium. I-Zirconium alloy ineepropathi ezigqwesileyo zoomatshini, ukumelana nokugqwala, kunye nokuzinza kwe-thermal. Iivalvu zesango le-Zirconium alloy zisetyenziswa ngokubanzi kwi-aerospace, ukwakha iinqanawa, iikhemikhali, ishishini lenyukliya, kunye namanye amasimi.
