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 ijoyinti yokushisela selipholile, faka i-valve ukuze uqinisekise ukuthi i-valve inesikhala esanele esinyakazayo ku-flange ukuvimbela i-valve ukuthi ingalimazi, futhi uqinisekise ukuthi ipuleti levemvane linezinga elithile lokuvula (i-valve butterfly valve idinga engeza i-gasket yokuvala); lungisa indawo ye-valve futhi uqinise wonke ama-bolts (qaphela ukuthi ungafaki isikulufu ngokuqinile); 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 ugesi, bese ucindezela inkinobho kagesi ukuhlola iswishi futhi ahlole indlela yokuvula i-valve yokuqondisa. wesondo lenkomba.
