Ezinhlelweni zamapayipi ezimboni, ukukhetha amavalvu kubalulekile, ikakhulukazi amavalvu amavemvane. Amavalvu amavemvane asetshenziswa kabanzi ngenxa yesakhiwo sawo esilula, ukumelana noketshezi oluphansi, kanye nokulula kokusebenza. Izinhlobo zamavalvu amavemvane ezivamile zifaka phakathiivalvu yebhabhathane eliyi-wafer, ivalvu yebhabhathane elijiyile, futhiivalvu yebhabhathane eligobileUma ukhetha uxhumano lwe-valve nepayipi, kubalulekile ukuqonda izici zezinhlobo ezahlukene ze-butterfly valve kanye nezimo zazo ezifanele.
Okokuqala, the ivalvu yebhabhathane eliyi-waferuhlobo oluvamile lwevalvu yebhabhathane, evame ukusetshenziswa phakathi kwepayipi. Ukwakheka kwayo kuyivumela ukuthi iboshwe ngqo phakathi kwezingxenye ezimbili zamapayipi, okwenza kube lula ukuxhumana futhi kwenze ifaneleke ukusetshenziswa okunesikhala esilinganiselwe. Izinzuzo zevalvu yebhabhathane ye-wafer zifaka phakathi isisindo sayo esilula kanye nokulula kokufakwa, okwenza ifaneleke ukulawula uketshezi oluphansi kanye noluphakathi. Uma ukhetha ivalvu yebhabhathane ye-wafer, qiniseka ukuthi ubukhulu beflange yepayipi buhambisana nobukhulu bevalvu ukuqinisekisa ukuvalwa okuphephile.
Okwesibili,amavalvu ebhabhathane acwebezelayozixhunywe kumapayipi ngama-flange. Lokhu kuxhuma kunikeza ukuvalwa okuthuthukisiwe kanye nokuqina, okwenza kufaneleke ukusetshenziswa komfutho ophezulu kanye nokushisa okuphezulu. Ukufakwa kwama-valve e-flange ahlanganisiwe kuyinkimbinkimbi kakhulu, kudinga ama-bolts ukuxhuma i-valve ne-flange yepayipi. Uma ukhetha i-valve ye-flangd butterfly, ngaphezu kokucabangela izinto ze-valve nosayizi, kubalulekile futhi ukucabangela indinganiso ye-flange (njenge-ANSI, i-DIN, njll.) kanye nezinto zokuvala ukuqinisekisa ukuphepha nokuthembeka ngaphansi kwezimo zomfutho ophezulu.
Ekugcineni,ivalvu yebhabhathane eligobileiyivalvu exhunywe ngomsele futhi ivame ukusetshenziselwa ukuqaqa nokulungisa ngokushesha. Amavalvu ebhabhathane anemifantu kulula kakhulu ukuwafaka nokuwasusa, okwenza afanelekele izinhlelo zamapayipi ezidinga ukushintshwa noma ukuhlanzwa njalo. Uma ukhetha ivalvu yebhabhathane enemifantu, cabanga ngezinto zepayipi kanye nobubanzi ukuqinisekisa ukuthi umsele ungabamba ivalvu ngokuphephile futhi uvimbele ukuvuza.
Uma ukhetha indlela yokuxhumanisa phakathi kwe-valve nepayipi, ngaphezu kokucabangela uhlobo lwe-valve, udinga futhi ukucabangela izici ezilandelayo:
1. Izici zoketshezi: Uketshezi oluhlukene (njengegesi, uketshezi, udaka, njll.) lunezidingo ezahlukene zamavalvu, ngakho-ke udinga ukukhetha uhlobo lwevalvu olufanele kanye nendlela yokuxhuma.
2. Ingcindezi yokusebenza kanye nezinga lokushisa: Ngaphansi kwengcindezi ephezulu kanye nezimo zokushisa okuphezulu, amavalvu e-flange butterfly angaba yisinqumo esingcono, kanti ngaphansi kwezimo zokucindezela okuphansi, ivalvu ye-wafer butterfly noma ivalvu ye-butterfly enemiphetho ingafaneleka kakhulu.
3. Isikhala sokufaka: Uma isikhala silinganiselwe, ukwakheka kwevalvu yevemvane ye-wafer kungonga isikhala, kuyilapho ivalvu yevemvane enemiphetho inikeza ukuguquguquka okukhulu.
4. Izidingo zokulungisa: Uma uhlelo lwamapayipi ludinga ukulungiswa njalo, isici sokuqaqa ngokushesha ivalvu yebhabhathane enemiphetho sizothuthukisa kakhulu ukusebenza kahle komsebenzi.
Ngamafuphi, ukukhetha ivalvu yebhabhathane efanele kanye nendlela yokuxhuma kwayo kubalulekile ekuqinisekiseni ukusebenza kahle nokuphephile kohlelo lwakho lokufaka amapayipi. Ukuqonda izici kanye nezimo ezifanele zezinhlobo ezahlukene zevalvu yebhabhathane kuzokusiza ukuthi wenze izinqumo ezinolwazi oluthe xaxa ekusetshenzisweni okusebenzayo. Kungakhathaliseki ukuthi iyi-ivalvu yebhabhathane eliyi-wafer, ivalvu yebhabhathane elijiyile, ivalvu yebhabhathane eligobile, indlela efanele yokuxhuma ingathuthukisa ukusebenza kanye nokuthembeka kwesistimu iyonke.
