Ku-workshop ye-Jinbin, i-12 flangeizivalo uvemvaneyokucaciswa kwe-DN450 sebeyiqedile yonke inqubo yokukhiqiza. Ngemva kokuhlolwa okuqinile, apakishwa futhi athunyelwa lapho eya khona. Leli qoqo lama-valve uvemvane lihlanganisa izigaba ezimbili: i-pneumatici-valve ye-butterfly ene-flangedkanye negiya lezikelemu ezine-flanged manual butterfly valve. Zizoklanywa ngokukhethekile izinhlelo zokukhipha igesi engcolile yezimboni futhi zingasebenza ngokuzinza endaweni yokusebenza engu-≤80℃.

Iuvemvane valve womoyaakhiqizwa ngalesi sikhathi acutshungulwa ngamasu anembe kakhulu. Indawo yokuvala ipuleti ye-valve ithole ukwelashwa okukhethekile ukuze kuqinisekiswe ukumelana nokugqwala okuhle kakhulu nokusebenza kokuvala emithonjeni yegesi yokukhipha umoya. Yonke imikhiqizo iphumelele izivivinyo zokumelana nengcindezi, ukutholwa kokuvuza kanye nezivivinyo zokulingisa isimo sokusebenza sezinga eliphezulu lokushisa. Zonke izinkomba zihambisana ngokugcwele nezindinganiso zezimboni, zinikeza iziqinisekiso ezinokwethenjelwa zokusebenza okuphephile kwesistimu yokwelapha igesi engcolile. 

Njengesigaba esibalulekile salokhu kuthunyelwa, ama-valve evemvane ane-pneumatic flanged athathe isikhundla esibalulekile emkhakheni wokulawula uketshezi lwezimboni ngenxa yezinzuzo zabo eziphawulekayo. Izinzuzo zayo eziyinhloko zibonakala ezicini ezintathu: Okokuqala, inesivinini sokuphendula esisheshayo. Ngokushayela i-actuator ngomoya ocindezelwe, ingakwazi ukufinyelela ukulawulwa kokuvula nokuvala kwezinga le-millisecond, futhi ingasabela ngokushesha ezinguqukweni eziguquguqukayo zokugeleza kwegesi yokukhipha umoya. Okwesibili, inezinga eliphezulu lokuhlanganisa okuzenzakalelayo, isekela ukuxhumana nohlelo lokulawula lwe-PLC, futhi ingasetha ukude i-Angle yokushintsha ukuze kuzuzwe ukulawulwa kokugeleza okunembile. Okwesithathu, izindleko zokunakekela ziphansi. I-actuator yomoya inesakhiwo esilula futhi ayikho inkinga yokushisa kwemoto. Ezimweni zokusebenza ezingaphansi kuka-80℃, impilo yayo yesevisi ingaphezu kuka-30% ubude kunaleyo yevalvu kagesi. 

Ngokwezimo zohlelo lokusebenza, ama-valve ovemvane ane-pneumatic flanged anezinhlobonhlobo zezicelo: ekwelapheni igesi engcolile yamapaki ezimboni zamakhemikhali, angasetshenziswa ngokuhambisana nezinhlelo zokuqapha eziku-inthanethi ukuze alungise ngokuzenzakalelayo ukuvulwa kwe-valve, ukuqinisekisa ukuthi ukugxilwa kokukhishwa kwe-VOCs kuhlala kuzinzile futhi kuhlangabezana nezindinganiso. Esigabeni sokuhlanzwa kwegesi eliwuketshezi lwezitshalo zamandla okushiswa kwemfucuza, inganqamula ngokushesha i-high-temperature flue gas passage futhi iqinisekise ukuphepha kokugcinwa kwemishini yokukhipha i-denitration. Kuhlelo lokuqoqwa kwegesi yokukhipha i-workshop yokudweba i-spray, ngokusebenzisa ukulawulwa kokuxhumana ne-fan, ivolumu yokukhipha ingalungiswa ngokuhlakanipha ngokuvumelana nesigqi sokukhiqiza, kuzuzwe izinzuzo ezimbili zokongiwa kwamandla nokuvikelwa kwemvelo. 

Amavalvu e-Jinbin akhethekile ekukhiqizeni ama-valve (abakhiqizi bovemvane) iminyaka engu-20. Uma unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo kungakapheli amahora angama-24!
