Ezinhlelweni zamapayipi ezimboni, ukukhethwa kwamavalvu kubalulekile, ikakhulukazi amavalvu ovemvane. Ama-valve e-butterfly asetshenziswa kakhulu ngenxa yesakhiwo sawo esilula, ukumelana noketshezi oluphansi, nokusebenza kalula. Izinhlobo ezivamile ze-butterfly valve zihlanganisai-wafer butterfly valve, i-valve ye-butterfly ene-flanged, futhigrooved uvemvane valve. Lapho ukhetha uxhumano lwe-valve ukuya epayipini, kubalulekile ukuqonda izici zezinhlobo zama-valve ovemvane ezihlukene kanye nezimo zazo ezisebenzayo.
Okokuqala, the i-wafer butterfly valvewuhlobo oluvamile lwevalve uvemvane, ngokuvamile esetshenziswa maphakathi nepayipi. Idizayini yayo ivumela ukuthi iboshwe ngokuqondile phakathi kwezingxenye ezimbili zamapayipi, kube lula ukuxhumana futhi ikwenze ifanele izinhlelo zokusebenza ezinendawo elinganiselwe. Izinzuzo ze-valve ye-butterfly valve ihlanganisa isisindo sayo esilula kanye nokulula ukuyifaka, okuyenza ifanelekele ukulawula uketshezi olunomfutho ophansi kanye nomfutho ophakathi. Lapho ukhetha i-valve uvemvane, qiniseka ukuthi ubukhulu bepayipi le-flange buhambisana nobukhulu be-valve ukuze uqinisekise uphawu oluvikelekile.
Okwesibili,ama-butterfly valvesaxhunywe kumapayipi ngama-flange. Lokhu kuxhumana kunikeza ukubekwa uphawu okuthuthukisiwe nokuzinza, okukwenze kulungele izinhlelo zokusebenza ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu. Ukufakwa kwama-valve ovemvane ane-flanged kuyinkimbinkimbi, kudinga amabhawodi ukuxhuma i-valve ku-flange yepayipi. Uma ukhetha i-valve ye-butterfly ye-flangd, ngaphezu kokucabangela impahla ye-valve nobukhulu, kubalulekile futhi ukucabangela izinga le-flange (njenge-ANSI, i-DIN, njll.) kanye nezinto zokuvala ukuze kuqinisekiswe ukuphepha nokuthembeka ngaphansi kwezimo eziphezulu zokucindezela.
Ekugcineni,grooved uvemvane valveiyi-valve exhunywe nge-groove futhi ivame ukusetshenziselwa ukuhlakazwa nokulungiswa okusheshayo. Ama-valve ovemvane ane-grooved kulula kakhulu ukuwafaka nokuwakhipha, okuwenza afanelekele izinhlelo zamapayipi ezidinga ukushintshwa noma ukuhlanzwa njalo. Lapho ukhetha i-valve uvemvane olugobile, cabangela impahla yepayipi nobubanzi ukuze uqinisekise ukuthi inkaba ingabamba ngokuphephile i-valve futhi ivimbele ukuvuza.
Lapho ukhetha indlela yokuxhuma phakathi kwe-valve nepayipi, ngaphezu kokucabangela uhlobo lwe-valve, udinga ukucabangela izici ezilandelayo:
1. Izici zoketshezi: Uketshezi oluhlukene (njengegesi, uketshezi, udaka, njll.) kunezidingo ezihlukene zamavalvu, ngakho-ke udinga ukukhetha uhlobo olufanele lwevalvu kanye nendlela yokuxhuma.
2. Ingcindezi yokusebenza kanye nezinga lokushisa: Ngaphansi kwengcindezi ephezulu kanye nezimo zokushisa eziphakeme, ama-valve evemvane e-flange angase abe ukukhetha okungcono, kuyilapho ngaphansi kwezimo eziphansi zengcindezi, i-wafer butterfly valve noma i-valve butterfly e-grooved ingase ifaneleke kakhulu.
3. Isikhala sokufaka: Uma isikhala silinganiselwe, ukuklanywa kwe-valve uvemvane oluyisicwecwana kungasindisa isikhala, kuyilapho i-valve uvemvane egobile inikeza ukuguquguquka okukhulu.
4. Izidingo zokunakekela: Uma isistimu yamapayipi idinga ukunakekelwa njalo, isici sokuqaqa ngokushesha se-valve uvemvane egobile sizothuthukisa kakhulu ukusebenza kahle.
Kafushane, ukukhetha i-valve yovemvane efanele kanye nendlela yokuxhuma kwayo kubalulekile ukuze kuqinisekiswe ukusebenza kahle nokuphephile kohlelo lwakho lwamapayipi. Ukuqonda izici nezimo ezisebenzayo zezinhlobo ezahlukene zamavalvu ovemvane kuzokusiza wenze izinqumo ezinolwazi oluningi ezinhlelweni ezisebenzayo. Noma ngabe ii-wafer butterfly valve, i-valve ye-butterfly ene-flanged, grooved uvemvane valve, indlela yokuxhumana efanele ingathuthukisa ukusebenza okuphelele nokuthembeka kwesistimu.
