6. I-flange ephakathi (ukuxhumana phakathi komzimba we-valve nomzimba wesobunxele) ayinakho isakhiwo sokuvuza.Ukuxhumana phakathi komzimba we-valve nomzimba wangakwesokunxele kuvalwe ngama-gaskets.Ukuze uvimbele ukuvuza ngenxa yomlilo, izinga lokushisa eliphezulu noma ukudlidliza, iklanyelwe ngokukhethekile Umzimba we-valve uthintana nensimbi-yensimbi emzimbeni wesobunxele ukuze wenze i-orifice flange engaguquki ukuze kuqinisekiswe ukuthi akukho ukuvuza.

 

7. Isakhiwo sokuvikela umlilo Uma kwenzeka ingozi yomlilo, izinto ezingezona ezensimbi ezifana nezihlalo zamavalvu nama-fillers zizoshiswa, futhi inani elikhulu lemithombo yezindaba eputshuziwe lingase liqhubekisele phambili umlilo.Isakhiwo se-valve esingashisi singavimbela inani elikhulu lokuvuza okuphakathi.Ngemva komlilo, izingxenye ezivuzayo (ibhola kanye nomzimba we-valve, isiqu se-valve kanye nomzimba we-valve, i-flange ephakathi) zenzelwe ukuthi zihlangane nensimbi ukuze zihlangabezane nezidingo zokuvikela umlilo.Njengoba kuboniswe emfanekisweni, lapho isihlalo se-valve sishiswa, ibhola lizothinta ngokuqondile indawo yensimbi yomzimba we-valve ngaphansi kwengcindezi, ngaleyo ndlela ivimbele inani elikhulu le-medium ekuvuzeni esihlalweni se-valve esishisiwe.

 

2. Isilinganiso Sezinga Lokushisa

 

Ukucindezela kanye nesilinganiso sokushisa kwe-valve yebhola akuhlobene nje kuphela nezinto zegobolondo, kodwa futhi kuhlobene kakhulu nezinto zokuvala ezifana nesihlalo se-valve, ukupakisha kanye ne-gasket.Isigxivizo singaba impahla ye-polymer, i-asbestos noma irabha.Ukukhethwa kwezinto zokufaka uphawu kuncike ekubunjweni okuphakathi, izinga lokushisa lokusebenza, ingcindezi yokusebenza kanye nezinga lokugeleza kwe-valve.

 

Ezimweni ezihlukahlukene zokusebenza ezingalindelekile, kunzima kakhulu ukucacisa ngokunembile isilinganiso sokushisa kwe-valve.Ngokusekelwe kulwazi lwethu lokukhiqiza ama-valve esikhathi eside kanye nempendulo ebalulekile evela kumakhasimende, silapha ukuze sikunikeze izilinganiso ze-pressure-temperature zama-valve ngaphansi kwezimo zokusebenza ezizinzile.

 

 

I-Nortech ingomunye wabakhiqizi abahamba phambili bamavalvu ezimbonini e-China abanesitifiketi sekhwalithi ye-ISO9001.
