Ukuqhathaniswa kokusebenza kwe-valve ye-butterfly enkulu ne-valve yesango:
I-valve yesango inomthamo omkhulu futhi ithatha indawo enkulu. Ingathwala ingcindezi enkulu.
I-valve ye-butterfly inevolumu encane futhi ithatha indawo encane. Ingakwazi ukumelana nengcindezi incane uma kuqhathaniswa.
Ukukhetha okuqondile, kodwa futhi cabangela izinga lokushisa le-medium, ukuvalwa kwe-valve nokupakisha.
Incazelo ibeka ukuthi i-valve uvemvane enobubanzi obungaphezu kuka-50cm kufanele isetshenziswe.
I-valve yovemvane enobubanzi obukhulu ingumkhiqizo omusha oyisihluthulelo kazwelonke. Ukusebenza okuphezulu kwe-butterfly valve isebenzisa i-eccentric ephindwe kabili kanye nesakhiwo esikhethekile se-cone elliptical seal. Ixazulula inkinga yokuthi indawo yokuvala ye-valve ye-eccentric butterfly isalokhu ishayisana ngokuslayida ngesikhathi sokuvulwa nokuvala ukusuka ku-0 ° kuya ku-10 ° futhi ifinyelela umphumela wokuhlukanisa indawo yokuvala ngesikhathi sokuvulwa nokuvala ngesikhathi sokuvala, ukuze kunwetshwe impilo yesevisi futhi kuzuzwe ukusebenza okuhle kakhulu kokuvala.
Ukusetshenziswa kwe-valve ye-butterfly enkulu:
Isetshenziselwa ipayipi legesi embonini ye-sulfuric acid:i-inlet kanye ne-outlet ye-blower phambi kwesithando somlilo, i-outlet kanye ne-outlet ye-relay fan, i-valve yochungechunge lwe-demister kagesi kanye ne-valve yokuxhuma, i-inlet ne-outlet ye-S02 main blower, ukulawulwa kwesiguquli, i-inlet kanye ne-outlet ye-preheater, njll. kanye nevolumu yegesi esikiwe. Isetshenziswa ekushiseni isibabule, ukuguqulwa kanye nesigaba sokumuncwa esomile sohlelo lwe-sulfuric acid evuthayo. Iwuphawu olukhethwayo lwamavalvu esitshalweni esivuthayo sesulfuric acid. Iningi labasebenzisi libhekwa njengama-valve ovemvane asebenza kahle ngokuvala, ukusebenza okulula, ukugqwala komkhiqizo, ukumelana nokushisa okuphezulu, ukusebenza okulula nokuguquguqukayo, ukusetshenziswa okuphephile nokuthembekile, futhi sekusetshenziswe kabanzi. Ibuye isetshenziswe kabanzi kumapayipi we-SO2, umusi, umoya, igesi, i-ammonia, i-CO2, uwoyela, amanzi, i-brine, i-alkali, amanzi olwandle, i-nitric acid, i-hydrochloric acid, i-sulfuric acid, i-phosphoric acid kanye neminye imidiya kumakhemikhali, i-petrochemical, ukuncibilika, imithi, ukudla nezinye izimboni njengemishini yokulawula kanye nokulawula.
Izici ze-valve ye-butterfly enkulu:
① Idizayini eyingqayizivele ye-eccentricity yezindlela ezintathu yenza idrayivu engaphezulu yokuvala ngaphandle kokungqubuzana futhi inwebe impilo yesevisi yevalvu.
② I-elastic seal ikhiqizwa nge-torque.
③ Indawo yokuvala ye-cuneiform inomsebenzi wokunxeshezelwa kokuvuza okuyiziro.
④ Ivolumu encane, isisindo esincane, ukusebenza okulula nokufaka kalula.
⑤ Ngokuya ngezidingo zabasebenzisi, amadivaysi omoya kanye nawogesi angalungiselelwa ukuhlangabezana nezidingo zesilawuli kude nokulawula uhlelo.
⑥ Impahla yezingxenye ezishintshayo ingasetshenziswa kuzo zonke izinhlobo zemidiya, futhi ingasetshenziselwa ulayini wokulwa nokugqwala (F46, gxpp, Po, njll.).
⑦ Ukuhlukahluka kwesakhiwo okuqhubekayo: i-clamp, i-flange, i-butt welding.
