Indlela Yokukhetha I-Butterfly Valve Efanele Yokwelashwa Kwamanzi

Izindawo zokuhlanza amanzi zibalulekile ekuhlinzekeni ngamanzi ahlanzekile naphephile ukuze kusetshenziswe izinto eziningi ezahlukene. Ama-valve e-Butterfly angenye yezingxenye ezibaluleke kakhulu endaweni yokuhlanza amanzi njengoba esetshenziselwa ukulawula ukugeleza kwamanzi kanye nenani lamakhemikhali asatshalaliswayo. Ukukhethwa kwe-valve ye-butterfly efanele kubalulekile ekusebenzeni kahle kwesikhungo, kunciphisa izindleko zokulungisa kanye nokuqinisekisa ukuthi ikhwalithi yamanzi ihlala iphezulu.

Ukubuka konke kweamavalvu ebhabhathane

Amavalvu e-Butterfly angamavalvu ajika ngekota asebenzisa idiski eyindilinga ukulawula ukugeleza koketshezi. Idiski ifakwe emshafini ojikelezayo, okuvumela ukuthi ibekwe ngendlela eqondile noma ehambisana nokugeleza. Uma idiski ihambisana nokugeleza, ivalvu ivulekile, futhi uma iqondile, ivalvu ivaliwe. Lawa mavalvu aziwa ngomklamo wawo omncane, ukwakheka okulula, kanye nokusebenza okusheshayo, okwenza abe afanele ukusetshenziswa ezitshalweni zokuhlanza amanzi.

Mina.Izinto Ezibalulekile Okufanele Uzicabangele Lapho Ukhetha Izici Zoketshezi Lwe-Butterfly Valve

Uhlobo loketshezi luyinto ebaluleke kakhulu lapho ukhetha okufaneleivalvu yebhabhathaneizinto zokwakha, ngakho-ke ukuqonda izakhiwo zoketshezi ezifana nokugqwala, i-viscosity, izinga lokushisa, nokuthi uketshezi lunezinhlayiya eziqinile ezilengayo noma cha. Isibonelo, amanzi agqwalayo azodinga i-valve yensimbi engagqwali noma i-valve ene-lining yerabha ukuze kugwenywe ukugqwala futhi kunikezwe isikhathi esiphezulu senkonzo.

II. Izinga Lokugeleza Nokucindezela

Izinga lokugeleza kanye nezidingo zokucindezela zesitshalo sokwelapha amanzi zibalulekile ekunqumeni usayizi ofanele kanye nohlobo lwevalvu yebhabhathane. I-valve flow coefficient (Cv) iyipharamitha ebalulekile ekhombisa ikhono layo lokulawula ukugeleza. Isilinganiso se-Cv esiphezulu sisho ukuthi ivalvu ingaphatha izinga lokugeleza elikhulu ngokuncipha okuncane kokucindezela. Ngaphezu kwalokho, isilinganiso sokucindezela kwamavalvu kufanele okungenani sibe sikhulu ngokuphindwe ka-1.5 kuya ku-2 kunengcindezi yokusebenza ephezulu yesistimu ukuqinisekisa ukusebenza okuphephile nokuthembekile.

III. Ukuhambisana kwezinto ezibonakalayo

Izinto ezisetshenziswa ekwakhiweni kwevalvu yebhabhathane kumele zihambisane namanzi nanoma yimaphi amakhemikhali asetshenziswa enkambisweni yokwelapha. Izinto ezivamile zamavalvu ebhabhathane zifaka insimbi engagqwali, insimbi ethambile, kanye namapulasitiki ahlukahlukene njenge-PVC, PP, kanye ne-PVDF. Ukukhetha izinto kuzoncika ezintweni ezifana nokumelana nokugqwala, izinga lokushisa, kanye nezindleko. Isibonelo, amavalvu ebhabhathane e-PVC avame ukusetshenziswa ezitshalweni zokwelashwa kwamanzi ngenxa yokumelana kwawo okuhle kwamakhemikhali kanye nokusebenza kahle kwezindleko.

IV. Uhlobo lweValve kanye nomklamo

Amavalvu ebhabhathane afika ngezinhlobo ezahlukene kanye nemiklamo, ngalinye linezinzuzo zalo kanye nokusetshenziswa kwalo. Izinhlobo ezimbili eziyinhloko amavalvu ebhabhathane aqinile kanye nalawo angavamile.Amavalvu ebhabhathane aqinilezilungele ukusetshenziswa kwamanzi ahlanzekile futhi zinikeza ukusebenza okuthembekile kokuvala.Amavalvu ebhabhathane ayingqayiziveleNgakolunye uhlangothi, zenzelwe ukusetshenziswa okunzima kakhulu okubandakanya umfutho ophezulu, izinga lokushisa eliphezulu, noma uketshezi oluqothulayo. Zinikeza ukuvala okungcono kanye nokuphila isikhathi eside kwenkonzo ezimweni ezinjalo.

V. Izinketho Zokusebenza

Indlela yokusebenza ingenye into ebalulekile okufanele icatshangelwe lapho ukhethaamavalvu ebhabhathaneUkusebenza ngesandla kufanelekile ezinhlelweni zokusebenza lapho kungadingeki ukulungiswa okuvamile. Kodwa-ke, ezinhlelweni eziyinkimbinkimbi kakhulu noma lezo ezidinga ukulawulwa okukude, izinketho zokwenza okuzenzakalelayo njenge-actuator kagesi, yomoya, noma ye-hydraulic zingadingeka. Ama-valve azenzakalelayo angahlanganiswa nezinhlelo zokulawula ukuze anikeze ukulawula nokugeleza okunembile kanye nokuqapha.

Isiphetho

Ukukhetha ivalvu yebhabhathane efanele yesitshalo sokwelapha amanzi kuhilela ukucabangela ngokucophelela izici ezahlukahlukene, okuhlanganisa izici zoketshezi, izinga lokugeleza, ingcindezi, ukuhambisana kwezinto, uhlobo lwevalvu, izinketho zokusebenzisa, izidingo zokufaka, kanye nokuhambisana nezindinganiso zemboni. Ngokucabangela lezi zici, ungakhetha ivalvu yebhabhathane ezohlinzeka ngokusebenza okuthembekile, inciphise izindleko zokulungisa, futhi iqinisekise ukusebenza kahle kwesitshalo sakho sokwelapha amanzi.
