Incwadi yenqubo yokufaka i-valve ye-butterfly kagesi

1. Beka ivalvu phakathi kwamaflange amabili afakwe ngaphambilini (ivalvu yebhabhathane yeflange idinga indawo yegasket efakwe ngaphambilini kuzo zombili izinhlangothi)

2. Faka amabhawodi namantongomane kuzo zombili iziphetho emigodini yeflange ehambisanayo kuzo zombili iziphetho (indawo ye-gasket yevalvu yeflange butterfly idinga ukulungiswa), bese uqinisa amamantongomane kancane ukuze ulungise ukuthamba komphezulu weflange.

3. Lungisa i-flange epayipini ngokuwelda nge-spot welding.

4. Susa ivalvu.

5. Shintshela i-flange ngokuphelele epayipini.

6. Ngemva kokuba ijoyinti lokushisela selipholile, faka ivalvu ukuqinisekisa ukuthi ivalvu inesikhala esanele esinyakazayo kuflange ukuvimbela ivalvu ukuthi ingonakali, futhi uqinisekise ukuthi ipuleti levemvane linezinga elithile lokuvula (ivalvu yevemvane yeflange idinga ukufaka i-gasket yokuvala); lungisa indawo yevalvu bese uqinisa wonke amabhawodi (qaphela ukuthi ungagoqi kakhulu); vula ivalvu ukuqinisekisa ukuthi ipuleti levevu lingavuleka futhi livaleke ngokukhululeka, bese wenza ipuleti levevu livuleke kancane.

7. Qinisa wonke amantongomane ngokulinganayo.

8. Qiniseka ukuthi ivalvu ingavuleka futhi ivaleke ngokukhululeka. Qaphela: qiniseka ukuthi ipuleti levemvane alithinti ipayipi.

Qaphela: ukushaywa kokuvula nokuvala kwendlela yokulawula kulungisiwe lapho ivalvu yebhabhathane kagesi iphuma efektri. Ukuze kuvinjelwe indlela engalungile lapho ugesi uxhunyiwe, umsebenzisi kufanele avule ngesandla indawo eyingxenye (50%) ngaphambi kokuxhuma ugesi, bese ecindezela inkinobho kagesi ukuhlola inkinobho nokuhlola indlela yokuvula ivalvu yesiqondiso sesondo lesikhombisi.
