I-BolonMAYELANA NATHI

I-valve yebhola elintantayo ye-TA2 ikhiqizwa kusetshenziswa imishini ye-TA2. I-TA2 iyi-titanium ehlanzekile yezimboni. Ngokokuqukethwe okuhlukile kokungcola, ihlukaniswe ngamabanga amathathu: TA1, TA2, kanye ne-TA3. Izakhi zokungcola kwe-interstitial zalezi zimboni ezintathu ze-titanium ezihlanzekile zikhula kancane kancane, ngakho amandla abo omshini nobulukhuni nakho kuyanda kancane kancane, kodwa ipulasitiki nokuqina kwazo kuncipha ngokufanele. I-titanium ehlanzekile yezimboni evame ukusetshenziswa embonini i-TA2, ngenxa yokumelana nokugqwala kwayo okusesilinganisweni kanye nezakhiwo zemishini ezibanzi. I-TA3 ingasetshenziswa uma izidingo eziphakeme zibekwe phezu kokumelana namandla.

I-valve yebhola entantayo eyenziwe nge-super duplex insimbi engagqwali (S32750) icutshungulwa. I-S32750 iyinsimbi engagqwali enokumelana okuhle nokugqwala namandla. Kungeyensimbi engagqwali ye-ferritic austenitic, equkethe kufika ku-25% chromium, 7% nickel, 4% molybdenum, kanye no-0.25% we-nitrogen.

Izihlungi ezimise u-Y (izihlungi ezimise okuka-Y) ziyithuluzi lokuhlunga elibaluleke kakhulu kumasistimu wamapayipi okudlulisa imidiya. Zivame ukufakwa endaweni yokufaka ama-valve okunciphisa ingcindezi, ama-valve okusiza, ama-valve ezinga lamanzi angashintshi, noma ezinye izinto zokusebenza zokususa ukungcola phakathi nendawo nokuvikela ukusetshenziswa okuvamile kwama-valve nemishini.

Ivalvu ye-titanium efojiwe iyivalvu eyenziwe ngensimbi yensimbi ye-titanium (B381 Gr. F-2). Amafilimu e-Titanium oxide anokuzinza okuhle nekhono lokuzibamba ezindaweni ezigqwala kakhulu, ezingamelana nokugqwala okuqinile ngaphansi kwezimo ezihlukahlukene zokusebenza ezinzima.

Ingxenye yokuvula neyokuvala yamavalvu esango lensimbi efojiwe yipuleti lesango, futhi isiqondiso sokuhamba kwepuleti lesango libhekene nesiqondiso soketshezi. Amavalvu esango ensimbi enziwe mbumbulu angavuleka ngokugcwele futhi avalwe ngokugcwele, futhi awakwazi ukulungiswa noma ukuphonswa. Ipuleti lesango le-valve yesango lensimbi efojiwe linezindawo ezimbili zokuvala, futhi imodi evame ukusetshenziswa kakhulu yevalvu yesango ukuthi izindawo ezimbili zokuvala zakha umumo we-wedge, futhi i-engeli ye-wedge iyahlukahluka ngemingcele ye-valve.

Indandatho yokuvala yevalvu yovemvane eqinile ene-eccentric inemiklamo emithathu: enamazinga amaningi, okunwebeka, nayo yonke insimbi. Konke ukuvalwa kwensimbi okuqinile kuhlukile ekuvaleni okuqinile okunamaleveli amaningi kanye nokufaka uphawu okuqinile okunwebekayo. Wonke ama-valve evemvane ensimbi avaliwe afanele izimo zokushisa eziphakeme.

Ngesikhathi sokusebenza kwe-trunnion mounted ball valve, wonke amandla akhiqizwa ukucindezela kwamanzi ebhola adluliselwa ku-bearing, okungeke kubangele ukuthi ibhola lihambe liye esihlalweni se-valve, futhi isihlalo se-valve ngeke sithwale ukucindezela okukhulu. Ama-valve ebhola angashintshi ane-torque ephansi, ukuguquguquka kwezihlalo ezincane, ukusebenza kokuvala okuzinzile, nempilo ende yesevisi. Womabili ama-valve ebhola anobubanzi obukhulu kanye naphezulu azoklanywa njengezakhiwo ezingaguquki.

I-valve yebhola yensimbi eyenziwe nge-trunnion eyenziwe ngensimbi eyenziwe ngomgunyathi ene-density ephakeme kakhulu kunaleyo yokuphonsa, efanele izimo zokucindezela okukhulu. I-valve yebhola yensimbi eyizingcezu ezintathu enengcindezi ephezulu ihlukanisa umzimba we-valve ube izingxenye ezintathu eduze kwesigaba se-perpendicular ku-eksisi yesiteshi se-valve ezihlalweni zamavalvu amabili. I-valve yonke i-symmetrical mayelana ne-eksisi emaphakathi yesiqu se-valve. I-valve yebhola engaguquki isetshenziswa kakhulu kumapayipi ukusika, ukusabalalisa, kanye nokuguqula isiqondiso sokugeleza okuphakathi.

I-F904L super austenitic insimbi engagqwali iyikhabhoni ephansi, i-nickel ephezulu, i-molybdenum austenitic insimbi engagqwali engamelana ne-acid enekhono elihle kakhulu lokuguqula i-activation passivation kanye nokumelana nokugqwala okuhle kakhulu. Inokumelana nokugqwala okuhle kuma-asidi angenayo i-oxidizing njenge-sulfuric acid, i-formic acid, ne-phosphoric acid, futhi inokumelana kahle nokugqwala kwe-pitting ion ku-neutral chloride ion equkethe imidiya. Ngesikhathi esifanayo, inokumelana kahle nokugqwala kwe-crevice kanye nokugqwala kwengcindezi.

I-valve yepulaki yohlobo lomkhono ikakhulukazi iqukethe umzimba wepulaki, umkhono, i-clamping nut, nesiqu se-valve. Umzimba wepulaki uwumzimba oyinhloko wevalvu, oneshaneli efanayo ngaphakathi njengepayipi. Umkhono utholakala phezulu emzimbeni wepulaki futhi wenza uphawu ngomzimba wepulaki. I-compression nut ixhunywe emzimbeni wepulaki ngochungechunge ukuze kulungiswe umkhono. Isiqu se-valve sidlula kumkhono futhi sixhunywe kwisondo lesandla noma idivayisi kagesi phezulu ukuze kusetshenziswe i-valve.

I-valve yembulunga, eyaziwa nangokuthi i-valve yokuvala, iyi-valve yokuvala ngempoqo. Ngakho-ke, lapho i-valve ivaliwe, ukucindezela kufanele kusetshenziswe ku-disc ye-valve ukuphoqa indawo yokuvala ukuze ingavuzi. Lapho i-medium ingena ku-valve isuka ngaphansi kwe-valve disc, ukumelana okudingeka kunqotshwe amandla okusebenza amandla aphikisanayo phakathi kwesiqu se-valve nokupakisha kanye nokucindezela okukhiqizwa ukucindezela kwe-medium. Amandla okuvala i-valve makhulu kunamandla okuyivula, ngakho ububanzi besiqu se-valve kufanele bube bukhulu, ngaphandle kwalokho kuzokwenza ukuthi isiqu se-valve sigobe.

I-BOLON igxile ekukhiqizeni ama-valve akhethekile, ikakhulukazi ama-valve esango le-zirconium. I-Zirconium 702C i-valve yesango i-zirconium alloy iyi-alloy material esebenza kakhulu eyakhiwe ikakhulukazi i-zirconium. I-Zirconium alloy inezakhiwo ezinhle kakhulu zemishini, ukumelana nokugqwala, nokuzinza kokushisa. Ama-valve esango le-Zirconium alloy asetshenziswa kabanzi ku-aerospace, ukwakha umkhumbi, amakhemikhali, imboni yenuzi, neminye imikhakha.
