Indlela yokulawula ngokunembile izinga lokugeleza kwama-butterfly valves?

Ukulawula okunembile kweuvemvane valveukugeleza kudinga ukucatshangelwa okuphelele kwezinto eziningi kanye nezinyathelo ezihlosiwe. Okokuqala, ukukhethwa kwama-valve ovemvane kubalulekile. Ukucaciswa okufanelekile kanye nezinhlobo zama-valve emvemvane kufanele kukhethwe ngokusekelwe ebangeni lokugeleza, izidingo zokucindezela, nezici eziphakathi kwezimo zokusebenza zangempela. Isibonelo, ezimweni lapho ukulawulwa kokunemba okuphezulu kuyadingeka futhi okuphakathi kuwuketshezi oluhlanzekile, ama-valve uvemvane avaliwe angasetshenziswa, anokusebenza okuhle kokuvala futhi anganciphisa umthelela wokuvuza kwangaphakathi ekulawuleni ukugeleza; Uma i-medium iqukethe ukungcola okuyizinhlayiyana, okuvalwe ngokuqinileuvemvane valveifaneleka kakhulu ukugwema indawo evalekayo ukuthi ingagqoki futhi ithinte ukunemba kokulungiswa.

Okwesibili, ukukhethwa kanye nokulungisa iphutha le-actuator yizinyathelo ezibalulekile. Ama-actuator kagesi anezici zesivinini sokuphendula esisheshayo nokunemba okuphezulu kokulungiswa. Ngokusetha ngokunembile imingcele yabo yokulawula, njengokunemba kwesignali yokulawula ukuvulwa kanye nesikhathi sokuphendula se-actuator, ukulawulwa okunembile kokuvula i-butterfly valve kungafinyelelwa, ngaleyo ndlela kulungiswe ngokunembile izinga lokugeleza; Ama-actuator womoya kudingeka aqinisekise ukutholakala kwegesi okuzinzile kanye nokulawulwa okunembile kokucindezela. Ngokulungisa i-valve yokulawula umoya ukuze ushintshe umfutho womoya ongena ku-actuator, ukuvulwa kwe-valve uvemvane kungalawulwa ngokunembile ukuze kuzuzwe ukulawula ukugeleza okunembile.

Ngaphezu kwalokho, inqubo yokufaka ayikwazi ukushaywa indiva. Amavalvu ovemvane kufanele afakwe kumapayipi avundlile, futhi i-valve shaft kufanele igcinwe endaweni evundlile ukuze kugwenywe izinguquko esimweni sokugeleza koketshezi okubangelwa ukutsheka kokufaka, okungase kuthinte ukunemba kokulawulwa kokugeleza; Ngesikhathi esifanayo, kuyadingeka ukuqinisekisa ukuthi ubude bezigaba zepayipi eziqondile ngaphambi nangemva kwe-uvemvane valveihlangabezana nezidingo. Ngokuvamile, ubude besigaba sepayipi eliqondile elingaphambili abukho ngaphansi kwezikhathi ezingu-10 ububanzi bepayipi, futhi ubude besigaba sepayipi eliqondile elingemuva abukho ngaphansi izikhathi ezi-5 ububanzi bepayipi, ukuze uketshezi lukwazi ukwakha isimo sokugeleza esizinzile ngaphambi kokungena ku-valve uvemvane, kunciphise ukuphazamiseka kwemisinga ye-eddy kanye nesiyaluyalu ekulinganisweni kokugeleza, futhi kunikeze idatha eyisisekelo enembile yokulawula okunembile.

Ngaphezu kwalokho, enqubweni yokusebenza yangempela, kuyadingeka ukusebenzisa amathuluzi okulinganisa ukugeleza njengamamitha okugeleza kwe-turbine, amamitha okugeleza kagesi, njll. ukuze kuqashwe ukugeleza ngesikhathi sangempela. Izimpawu zokugeleza ezilinganisiwe zibuyiselwa ohlelweni lokulawula, futhi uhlelo lokulawula lulungisa ngokuzenzakalelayo ukuvulwa kwe-valve ye-butterfly ngokusekelwe ekuphambukeni phakathi kwenani lokugeleza elibekiwe kanye nenani langempela lokulinganisa, ukwakha ukulawulwa kwe-loop evaliwe nokufeza ukulawula ukugeleza okunembile; Ngesikhathi esifanayo, ukugcinwa okuvamile nokugcinwa kwama-valve ovemvane, ukuhlola ukugqokwa kwezimpawu, ukuguquguquka kwama-valve shafts, nokushintshwa ngesikhathi kwezingxenye ezilimele kuyizinyathelo ezibalulekile zokuqinisekisa ukuthi ama-butterfly valves ahlala esesimweni esihle sokusebenza nokulawula ukugeleza okunembile.
