I-GB Hard and Soft Sealing Amavalvu Ebhola Antantayo Uhlolojikelele: Ukusebenza, Isicelo, Namazinga
Ivalvu yebhola elintantayo elisezingeni likazwelonke elithambile neliqinile ivalvu esetshenziselwa ukulawula imigudu yoketshezi, esebenza kahle yokuvala kanye nokumelana noketshezi oluncane. Kulesi sihloko, sizokwethula izici, izinhlelo zokusebenza, kanye nokucaciswa okuyinhloko kokusebenza kwamavalvu ebhola athambileyo futhi avaliwe ngokuqinile.
1. Izici zomkhiqizo
Ivalvu yebhola elintantayo elisezingeni likazwelonke elithambile neliqinile linezici ezilandelayo:
-Ukumelana noketshezi oluphansi: Ama-valve ebhola anokumelana noketshezi oluphansi kakhulu kuzo zonke izinhlobo zama-valve, ngisho nama-valve amabhola ancishisiwe, ukumelana kwawo noketshezi kuncane.
-Ukuvula nokuvala okusheshayo nokulula: Uma nje isiqu se-valve sizungeza i-90 °, i-valve yebhola izoqedela ukuvulwa okugcwele noma isenzo sokuvala esigcwele, okwenza kube lula ukufeza ukuvulwa nokuvala okusheshayo.
-Ukusebenza kahle kokuvala: Isihlalo se-valve yebhola sivaliwe, ngokusebenza okuhle kokuvala.
2. Ukusetshenziswa komkhiqizo
Ivalvu yebhola elintantayo elisezingeni likazwelonke elithambile neliqinile lilungele uphethiloli, igesi yemvelo, amakhemikhali, ezemithi, ukudla, ugesi, ukuphakelwa kwamanzi, i-metallurgy, kanye nezimboni zokwakha. I-valve yebhola elintantayo ye-Flange iyindlela evamile yokuxhuma, efanelekayo izimo ezihlukahlukene zokusebenza.
3. Ukucaciswa kokusebenza okuyinhloko
Ukucindezela okuzisholo (MPa): Uhla lokucindezela okulinganiselwe lwevalvu yebhola elintantayo elisezingeni likazwelonke elithambile neliqinile lingu-0.6~42.0 MPa, futhi amazinga okucindezela afanelekile angakhethwa ngokuvumelana nezimo zokusebenza ezihlukene.
Izinga lokushisa elisebenzayo: Ibanga lokushisa elisebenzayo lamavalvu ebhola antantayo ajwayelekile ajwayelekile futhi avalwe kanzima lingu-196 ℃~550 ℃, kuyilapho amavalvu ebhola antantayo athambile futhi avalwe kanzima amelana nesibabule afanele igesi yemvelo, i-petroleum nezinye izinto eziqukethe i-H2S. kanye ne-CO2.
Imidiya esebenzayo: Amavalvu ebhola athambile futhi avalwe kanzima ajwayelekile afanele imithombo yezindaba efana namanzi, isitimu, uphethiloli, igesi eliwuketshezi, negesi yemvelo.
4. Izinto zokwakha eziyinhloko
Izingxenye eziyinhloko ze-valve yebhola elithambile nelivaliwe eliqinile kazwelonke ihlanganisa uchungechunge lwensimbi ye-carbon steel, uchungechunge lwensimbi engagqwali, uchungechunge olungazweli sulphur, nochungechunge lwensimbi enezinga lokushisa eliphansi. Lezi zinto zingahlangabezana nezidingo zezimo ezahlukene zokusebenza, ukuqinisekisa ukuqina nokuthembeka kwe-valve.
5. Izindinganiso zokubulawa
Ivalvu yebhola elintantayo elisezingeni likazwelonke elithambile neliqinile lakhiwe futhi lakhiwe ngokuhambisana namazinga afana ne-GB/T12237, GB/T12221, GB/T12224, kanye ne-GB/T12220. Lezi zindinganiso zicacisa izidingo zobude besakhiwo, ama-flange axhumayo, ukuhlolwa nokuhlolwa kwama-valve, ukuqinisekisa ikhwalithi yomkhiqizo othembekile.
Kafushane, i-valve yebhola elintantayo elisezingeni likazwelonke elithambile neliqinile liyi-valve esebenza kahle kakhulu, esetshenziswa kabanzi emikhakheni yezimboni ehlukahlukene. Ukuqonda izici zayo, ukusetshenziswa, kanye nokucaciswa kokusebenza okuyinhloko kungasisiza ukuthi sikhethe kangcono futhi sisebenzise lolu hlobo lwevalvu.
