Izici ze-valve butterfly ezishiselayo nendawo yokusebenzisa, kanye nezinyathelo zokuphepha zokuthenga, nokugcinwa kwesingeniso esinemininingwane

Izici zevalve uvemvane wokushisela nendawo yokusebenzisa, kanye nezinyathelo zokuphepha zokuthengwa kwempahla, kanye nokugcinwa okuningiliziwe kwesingeniso sovemvane lwe-Welding iyi-valve yokulawula ipayipi evamile, esetshenziselwa kakhulu ukulawula ukugeleza koketshezi epayipini. Izici zayo eziyinhloko zimi kanje: 1. Isakhiwo esilula, usayizi omncane, isisindo esincane, kulula ukuyifaka nokugcina. 2. Ukushisela ngokuqondile ngepayipi, ukumelana noketshezi kuncane, ukusebenza kokugeleza kuhle. 3. Ngokusebenza okuhle kokubeka uphawu, kungavimbela ngempumelelo ukuvuza koketshezi. 4. Ifanele ukulawula imidiya ehlukahlukene, njengoketshezi, igesi kanye nempushana. 5. Ukumelana nokugqwala, ukumelana nokushisa okuphezulu, kulungele zonke izinhlobo zemvelo enokhahlo. I-valve ye-butterfly yokushisela isetshenziswa kakhulu kumakhemikhali, i-petroleum, i-metallurgy, iphepha, ukudla nemithi kanye nezinye izimboni, ezivamile endaweni yokuthutha yegesi, amanzi, uwoyela kanye ne-asidi kanye nesistimu yamapayipi e-alkali. Ukuthenga i-valve ye-butterfly yokushisela kudingeka inake amaphuzu alandelayo: 1. Ukucaciswa kanye nezinto zokwakha ama-butterfly valves azohlangabezana nezidingo zokusetshenziswa, futhi kufanele zenziwe ngokuhambisana nezindinganiso ezifanele ukuze kuqinisekiswe ikhwalithi nokusetshenziswa komphumela. 2. Kufanele kuqashelwe ukukhethwa kwempahla yokuvala ama-valve ukuze kuqinisekiswe ukuthi ihlangabezana nezidingo zemvelo nezinga lokushisa kwendawo. 3. Khetha uhlobo olulungile kanye nesakhiwo se-valve butterfly yokushisela ukuze uhlangabezane nezidingo zezindawo zokusebenza ezihlukene kanye namazinga okugeleza. 4. Abakhiqizi be-valve butterfly abavamile kufanele bakhethwe, futhi izinga nokusebenza kwemikhiqizo ye-valve kufanele kuhlolwe ukuze kuqinisekiswe ukwethembeka nokuphepha kwemikhiqizo. Ukugcinwa kwe-valve ye-butterfly ye-welding kudingeka inake amaphuzu alandelayo: 1. Hlola ngezikhathi ezithile isimo sokusebenza nokusebenza kokuvala kwe-valve ye-butterfly yokushisela, futhi ubhekane nezinkinga ezingenzeka ngesikhathi. 2. Gcina ivalvu ihlanzekile futhi ihlanzekile, futhi ukhiphe ukungcola nokungcola epayipini kusenesikhathi ukuze uqinisekise ukusebenza okuvamile kwevalvu. 3. Hlola ukuthi impahla yokuvala i-valve yonakele noma iyaguga. Uma kukhona inkinga, yishintshe kusenesikhathi. 4. Gcina idivayisi yokudlulisa ama-valve kanye nezinsiza zokungenisa umoya ukuze unciphise ukuguga nokwehluleka kwemishini. 5. Ngesikhathi sokufakwa, ukunakwa kufanele kukhokhwe ekuqondeni kwepayipi kanye nendawo ye-valve ukuze kugwenywe ukungahambi kahle noma ukushintsha okungalungile. 6. Uma i-valve ye-butterfly ye-welding imisiwe noma igcinwe isikhathi eside, qaphela i-anti-corrosion kanye ne-dust-proof, futhi uhlole isimo sayo sokusebenza nokusebenza kokuvala uphawu njalo.
