Imanuwali yenqubo yokufaka yevalvu yevemvane kagesi

1. Beka i-valve phakathi kwama-flange amabili afakwe ngaphambili (i-valve uvemvane we-flange idinga indawo efakwe ngaphambili ye-gasket kuzo zombili iziphetho)

2. Faka amabhawodi namantongomane kuzo zombili iziphetho ezimbotsheni ze-flange ezihambisanayo kuzo zombili iziphetho (indawo ye-gasket ye-valve butterfly valve idinga ukulungiswa), futhi uqinise amantongomane kancane ukuze ulungise ukucaba kwendawo ye-flange.

3. Lungisa i-flange epayipini ngokushisela indawo.

4. Khipha i-valve.

5. Weld flange ngokuphelele ipayipi.

6. Ngemva kokuba i-joint yokushisela isipholile, faka i-valve ukuze uqinisekise ukuthi i-valve inendawo eyanele yokuhamba e-flange ukuvimbela i-valve ukuthi ingalimazi, futhi uqinisekise ukuthi ipuleti le-butterfly linezinga elithile lokuvula (i-valve butterfly valve idinga ukwengeza i-gasket yokuvala); lungisa indawo ye-valve futhi uqinise wonke ama-bolts (nakisisa ukuthi ungakulungi kakhulu); vula i-valve ukuze uqinisekise ukuthi ipuleti le-valve lingavuleka futhi livale ngokukhululeka, bese wenza ipuleti levalvu livuleke kancane.

7. Qinisa wonke amantongomane ngokulinganayo.

8. Qiniseka ukuthi i-valve ingavuleka futhi ivaleke ngokukhululekile. Qaphela: qiniseka ukuthi ipuleti levemvane alilithinti ipayipi.

Qaphela: i-stroke yokuvula nokuvalwa kwendlela yokulawula ishintshiwe lapho i-valve uvemvane kagesi iphuma efektri. Ukuze uvimbele indlela engalungile lapho amandla exhunywe, umsebenzisi kufanele avule ngesandla afinyelele kuhhafu (50%) isikhundla ngaphambi kokuxhuma ukunikezwa kwamandla, bese ucindezela inkinobho kagesi ukuze uhlole iswishi futhi uhlole indlela yokuvula i-valve yokuqondisa yesondo lenkomba.
