I-valve yevemvane yomugqa omaphakathi iyivalvu yokulawula evame ukusetshenziswa, engadlala indima ebalulekile ekusimamiseni izinga lokugeleza nokulawula ukucindezela ohlelweni loketshezi. Ukukhetha uhlobo olulungile lwe-valve uvemvane lomugqa ophakathi kubaluleke kakhulu ekusebenzeni okuzinzile kwesistimu. Lesi sihloko sizokwethula isimiso esiyisisekelo se-valve ye-butterfly yomugqa ophakathi, nendlela yokukhetha uhlobo olufanele ngokuvumelana nezidingo zesistimu, ukuze kuqinisekiswe ukuzinza nokusebenza kahle kokusebenza kwesistimu.
Okokuqala, isimiso esiyisisekelo somugqa ophakathi uvemvane valve
I-valve ye-butterfly yomugqa ophakathi i-valve ene-disc emzimbeni we-valve njengengxenye yokuvala, futhi uketshezi lulawulwa futhi lulungiswe ngokuzungezisa i-disc. Isakhiwo sayo esiyisisekelo sihlanganisa umzimba we-valve, isiqu se-valve, i-valve disc nokunye. Umzimba we-valve uyingxenye eyinhloko ye-valve futhi unokuvulwa kwevemvane ukuze kudlule uketshezi. Isiqu sixhuma i-valve disc kanye nendlela yokusebenza, futhi silawula ukucisha nokulawulwa koketshezi ngokuzungezisa idiski ye-valve.
I-valve ye-butterfly yomugqa ophakathi ibonakala ngesakhiwo esilula, usayizi omncane, isisindo esilula nokusebenza okuhle kokulawula uketshezi. Ngenxa yokuthi i-disc ingavulwa ngokugcwele, ivalwe ngokugcwele futhi ilungiswe kunoma yisiphi isikhundla, i-valve ye-butterfly yomugqa ophakathi isetshenziswa kabanzi ekulawuleni ukugeleza nokulawulwa kokucindezela.
Okwesibili, khetha uhlobo olulungile lwe-valve ye-butterfly factor
1. Izici zemidiya ye-Fluid: Imidiya ehlukene ye-fluid inezidingo ezihlukene zezinto kanye nokuvala i-valve. Isibonelo, imidiya ebolayo idinga ukukhetha izinto ezimelana nokugqwala, imidiya yokushisa ephezulu idinga ukukhetha izinto ezimelana nokushisa okuphezulu. Ngakho-ke, lapho ukhetha uhlobo lwe-butterfly valve, izici ze-fluid medium kufanele zicatshangelwe ngokugcwele, futhi izinto ezihambisanayo kanye nesakhiwo sokubeka uphawu kufanele kukhethwe.
2. Ingcindezi yokusebenza kanye nezinga lokushisa: Ingcindezi yokusebenza kanye nobubanzi bokushisa bevalve uvemvane womugqa ophakathi nakho kuyizici ezibalulekile ekukhetheni. Ngokwezimo ezithile zokusebenza, khetha uhlobo lwe-valve butterfly ephakathi nendawo engakwazi ukumelana nokucindezela okuhambisanayo kanye nezinga lokushisa ukuze uqinisekise ukwethembeka nokuphepha kwe-valve.
3. Izidingo zokugeleza: Thola usayizi kanye nendlela yokugeleza yevalve uvemvane yomugqa omaphakathi ngokwezidingo zokugeleza kohlelo. Kumele kuqashelwe ukuthi uma izinga lokugeleza ohlelweni likhulu noma kukhona ukugeleza kwe-pulsating, uhlobo lwe-valve butterfly yomugqa ophakathi nendawo enezici ezinhle ze-hydrodynamic, ukumelana nokugeleza okuphansi nomsindo ophansi kufanele kukhethwe.
4. Sebenzisa izimo zemvelo: Uma ucabangela indawo esetshenziswayo yomugqa ophakathi uvemvane valvu, njengokudlidliza, ukugqwala, izinga lokushisa eliphezulu nezinye izici, khetha uhlobo lwevalve uvemvane yomugqa ophakathi nokuvumelana nezimo. Ngaphansi kwezimo ezikhethekile zemvelo, kuyadingeka futhi ukucabangela ukusebenza kokuvala kanye nokumelana nokugqwala kwe-valve.
Ezintathu, izinhlobo zamavalvu ovemvane omugqa ophakathi nendawo
Ngokuya ngezidingo ezihlukene zesistimu yoketshezi, izinhlobo ezijwayelekile zamavalve uvemvane ophakathi zimi kanje:
1. I-valve uvemvane oluyi-eccentric olulodwa: I-valve uvemvane oluyi-eccentric olulodwa lunokungqubuzana okuphansi kanye ne-torque evalayo, ilungele ukulawula ukugeleza nokulawula okujwayelekile.
2. I-valve uvemvane eccentric kabili: Ivalve uvemvane eccentric ephindwe kabili inokumelana nokucindezela okuphezulu nokusebenza kangcono kokuvala kunevalve uvemvane oluyi-eccentric eyodwa, elifanele izikhathi ezithile ezinezidingo zokuvaleka eziphezulu.
3. Ivalvu yovemvane ene-eccentric: Ivalve yovemvane ene-eccentric eccentric ithuthukiswa futhi ngesisekelo se-valve uvemvane ene-eccentric ephindwe kabili, evaleka kakhulu futhi imelana nokugqwala, esetshenziswa kabanzi ekugelezeni kwesidingo esikhulu kanye nezikhathi zokulawula ingcindezi.
4. I-valve ye-butterfly yokushisa ephezulu: ukushisa okuphezulu kwe-butterfly valve ithatha ukushisa okuphezulu okungamelana ne-alloy impahla kanye nesakhiwo esikhethekile sokubeka uphawu, ingasebenza ngokuzinzile endaweni yokushisa ephezulu, ifanele ukucwenga uwoyela, imboni yamakhemikhali neminye imikhakha.
5. I-valve uvemvane edonsayo: i-valve uvemvane edonsayo isebenzisa ukwakheka kwesiteshi sokugeleza okuhlukaniswe izingxenye, okunganciphisa ithonya lokugeleza kwe-pulsating ku-valve futhi kugcine ukuzinza koketshezi. Ilungele uhlelo olunomfutho omkhulu wokugeleza.
6. I-valve ye-butterfly ekhethekile yezinto ezibonakalayo: i-valve ye-butterfly ekhethekile ifanele imidiya ekhethekile noma izimo ezikhethekile zokusebenza, njenge-asidi eqinile, i-alkali eqinile, igesi yokuhlanzeka okuphezulu, njll. Khetha i-valve yempahla ekhethekile ehambisanayo ukuze uqinisekise ukusebenza okuzinzile kwesistimu.
Iv. Isifinyezo
Ukukhetha uhlobo olufanele lwevalve uvemvane kubaluleke kakhulu ekusebenzeni okuzinzile kwesistimu yoketshezi. Ngokusho kwezici ze-fluid medium, ingcindezi yokusebenza kanye nezinga lokushisa, izidingo zokugeleza nokusetshenziswa kwezimo zemvelo nezinye izici, ukukhethwa okunengqondo kwezinto ezibonakalayo ze-valve butterfly line, ukuvala ukusebenza kanye nohlobo. Izinhlobo zama-valve uvemvane ophakathi nendawo zifaka i-valve uvemvane oluyi-eccentric olulodwa, i-valve uvemvane ene-eccentric ephindwe kabili, i-valve uvemvane ene-eccentric, izinga lokushisa eliphezulu valve uvemvane, i-valve uvemvane ephehlayo kanye ne-valve uvemvane. Ukukhetha uhlobo olufanele lwe-valve ye-butterfly yomugqa ophakathi ngokuvumelana nezidingo ezithile kungaqinisekisa ukusebenza okuzinzile kwesistimu futhi kuthuthukise ukusebenza kahle nokuthembeka kokulawula uketshezi.
Ngithemba ukuthi lesi sihloko sizokusiza ukuthi ukhethe uhlobo olufanele lwe-valve butterfly ukuqinisekisa ukuzinza nokusebenza kahle kokusebenza kwesistimu. Ukuze uthole ulwazi olwengeziwe, sicela ukhululeke ukuxhumana nochwepheshe noma umkhiqizi wamavalvu e-LIKV ukuze uthole ulwazi oluthe xaxa nezeluleko.
