Ithonya lokukhethwa kwezinto ezibonakalayo ze-butterfly valve empilweni yesevisi

Umthelela wokukhethwa kwezinto ezibonakalayo zei-butterfly valve manualempilweni yesevisi

I-valve uvemvane imanuwali iyivalvu yokulawula evamile evame ukusetshenziswa ukulawula ukugeleza nokucindezela emigqeni yoketshezi. Izinto ezihlukile ze-valve ye-butterfly zinomthelela oqondile empilweni yesevisi, ngakho-ke lezi zici ezilandelayo zidinga ukucatshangelwa lapho kukhethwa impahla ye-valve efanele:

1. Izinto eziwuketshezi
Impahla yevalvu kufanele ikhethwe ngokwesimo soketshezi, njengempahla enokusebenza okuhle kokugqwala lapho kunoketshezi olunamandla olugqwalayo. Uma izinga lokugeleza koketshezi lishesha, kufanele kusetshenziswe izinto ezinamandla kakhulu.

2. Izinga lokushisa nokucindezela
Impahla ye-valve kufanele futhi ikhethwe ngokuya ngokushisa koketshezi nokucindezela. Ezimweni zokushisa eziphakeme kanye nengcindezi ephakeme, kuyadingeka ukusebenzisa izinto zokushisa eziphakeme kanye nezinto ezicindezelayo ukwenza ama-butterfly valves ukuze kuqinisekiswe ukuthi ama-valve angasebenza ngokujwayelekile futhi angeke alimale noma ahluleke ngenxa yokushisa okuphezulu noma ukucindezela.

3. Ukumelana nokugqwala
Kweminye imikhakha ekhethekile njengokuhlanza amanzi angcolile, ukukhiqizwa kwamakhemikhali kanye nezimayini zasolwandle, uketshezi lunezakhiwo ezinamandla ezigqwalayo. Ngakho-ke, kuyadingeka ukukhetha izinto ezinokumelana nokugqwala okungcono ukwenza ama-valve.

Ama-butterfly valves wezinto ezihlukahlukene anezinzuzo kanye nokubi, okulandelayo yizinto eziningana:

1. I-valve yensimbi engagqwali
Insimbi engagqwali ingenye yezinto ezivamile ze-valve, ezinokuqina okuqinile nokumelana nokugqwala, ngakho-ke izinto zensimbi engagqwali zivame ukusetshenziswa ekukhiqizeni ama-butterfly valves. Ama-valve ensimbi engagqwali anzima kakhulu, kodwa anempilo ende yesevisi futhi avame ukusetshenziswa ezimeni ezinezidingo eziphakeme zokumelana nokugqwala.

2. Ama-valve ensimbi
Ama-valve ensimbi ashibhile, kodwa alula futhi aguga kalula. Ifanele ingcindezi ephansi kanye nemvelo yokushisa ephakathi, impilo yesevisi ifushane.

3. I-Titanium alloy valve
I-Titanium alloy valve inokumelana nokugqwala okuhle, ukumelana nokugqwala, ingasetshenziswa ku-asidi, i-alkaline, usawoti we-chlorine nakwezinye izindawo ezinokhahlo. Nokho, ngenxa yezinto ezikhethekile, intengo ibiza kakhulu.

4. Ama-valve epulasitiki
Izinto zePlastiki zinokumelana nokugqwala okuhle, ezifanele izimboni zamakhemikhali, ezemithi nezinye zokwelashwa koketshezi olugqwalile. Kodwa-ke, impilo yesevisi ifushane, futhi ingcindezi kanye nebanga lokushisa elingakwazi ukumelana nalo nalo lilinganiselwe.

Lapho ukhetha i-valve ye-butterfly, kuyadingeka ukukhetha izinto ezifanele ngokuya ngezici ezinjengokucindezela, izinga lokushisa, izakhiwo eziwuketshezi kanye nokugqwala endaweni yokusetshenziswa ukuze kuqinisekiswe ukusebenza okuvamile kwe-valve, ukunweba impilo yesevisi, nokunciphisa izinga lokushisa. inombolo yesondlo kanye nezindleko.
