Indima ephambili yokunyuka kunye nokuhla kweevalve zokukhupha ii-valve kulawulo lwenkqubo yeekhemikhali
Kwintsimi yolawulo lwenkqubo yeekhemikhali, ulawulo oluchanekileyo lolwelo lungundoqo ekuqinisekiseni umgangatho wemveliso kunye nokusebenza kakuhle kwemveliso. Njengenxalenye ebalulekileyo yenkqubo yokulawula inkqubo, i-valve yokukhupha i-up and down expansion ibonelela ngesisombululo esithembekileyo sokulawula ukujikeleza. Eli nqaku liza kuphonononga iindima eziphambili ezidlalwa zezi ntlobo zimbini zokukhupha iivalve kulawulo lwenkqubo yemichiza.
Ukulawulwa kokuhamba kunye nokusebenza kokutywinwa
Uyilo olulodwa lweevalvu ezikhuphayo ezinyukayo nasezantsi zenza ukuba uvule ngokukhawuleza kunye nokuvala izenzo, okubalulekileyo kwiinkqubo zeekhemikhali ezifuna ukutshintshwa rhoqo. Ngokuqhelekileyo baxhotyiswe nge-pneumatic okanye i-hydraulic actuators, enokufikelela kulawulo olukude kunye nokubonelela ngeendlela zokusebenza ezikhuselekileyo nezifanelekileyo. Ngokuphathelele ukutywinwa, ezi zivalo zinokuthintela nakuphi na ukuvuza okuphakathi kwimeko evaliweyo, ukuqinisekisa ukuqhubeka kwenkqubo yeekhemikhali kunye nokucoceka kwendalo.
Ulawulo olusebenzayo lwezinto ezikhutshwayo
Kwinkqubo yokuvelisa imichiza, kudla ngokuyimfuneko ukongeza okanye ukususa izinto kwi-reactor ngamaxesha athile. I-valve yokukhupha phezulu nangaphantsi inokusabela ngokukhawuleza kwimiyalelo yenkqubo yokulawula kwaye ilawule ngokuchanekileyo ukuhamba kwezinto. Obu buchule bokusabela ngokukhawuleza bubalulekile ekuthinteleni iimeko ezinjengokusabela okugqithisileyo okanye okungonelanga, ngaloo ndlela kuqinisekisa ukusebenza kakuhle kweekhemikhali kunye nomgangatho weemveliso.
Ukusetyenziswa kwendawo kunye nokufakela ukuguquguquka
Ngenxa yokuguquguquka koyilo, i-valve yokukhupha i-up and down yokwandisa ingafakwa phezulu okanye ezantsi kombhobho ngokweemfuno zangempela, okwenza ukuba zifaneleke kakhulu kwiimeko ezinendawo encinci. Oku kubaluleke ngakumbi kwizityalo zemichiza ezicwangciswe ngokuxineneyo, njengoko zivumela iinjineli ukuba ziphucule uyilo lwezixhobo kunye nokunciphisa ukusebenza kwendawo enyiniweyo.
Umda wosetyenziso olwahlukeneyo
I-valve yokukhupha i-up and down ingasetyenziselwa ukuphatha iikhemikhali ezahlukeneyo, kubandakanywa i-corrosion, i-viscosity ephezulu, okanye i-media equkethe amasuntswana aqinileyo. Ngokweemfuno ezahlukeneyo zesicelo, izixhobo zomzimba wevalve kunye nesiseko sevalve zinokwenziwa ngokwezifiso, njengokusebenzisa insimbi engenasici, i-Hastelloy alloy okanye ezinye iialloys ezikhethekileyo, kunye nerabha okanye i-PTFE (i-polytetrafluoroethylene) njengezinto zokutywina ukuze ziqhelanise nemidiya eyahlukeneyo yemichiza. kunye neendawo zokusebenza.
Ukhuseleko kunye nokuKhuselwa kokusiNgqongileyo
Kwishishini lemichiza, ukhuseleko kunye nokukhuselwa kokusingqongileyo yimiba emibini ebalulekileyo engenakunakwa. Uyilo lwe-valve yokukhupha i-up and down expansion iqinisekisa ukuba izinto eziphathekayo zinokukhutshwa ngokukhawuleza kwiimeko ezingxamisekileyo, ukukhusela iingozi ukuba zenzeke. Ngeli xesha, iimpawu zabo zokuvuza ezinokuthi zincede ukunciphisa iimpembelelo ezinokuthi zibe kho kokusingqongileyo kwaye zithobele imithetho engqongqo ekhoyo ngoku yokusingqongileyo.
Isishwankathelo, iivalvu zokukhupha ezandisiweyo eziphezulu nasezantsi zidlala indima ebaluleke kakhulu kulawulo lwenkqubo yemichiza. Ababoneleli kuphela ngezisombululo ezisebenzayo nezithembekileyo zokulawula ukuhamba, kodwa bafaka isandla ekukhuseleni kunye nokukhuselwa kokusingqongileyo kwimveliso yeekhemikhali. Ngokuqhubela phambili okuqhubekayo kwethekhinoloji, ukusebenza kwezi valuvu zokukhupha kuya kuqhubeka nokuphucula ukuhlangabezana neemfuno ezikhulayo zeshishini lemichiza.
