Ohlelweni lwegesi yemvelo ekhaya, maningi amavalvu egesi.Zifakwe ezindaweni ezahlukene futhi zidlala imisebenzi ehlukene.Sizowachaza ngokwehlukana.

1. Ivalvu yasendlini: ngokuvamile itholakala lapho ipayipi legesi lingena khona endlini, esetshenziselwa ukulawula ukuvuleka nokuvalwa kwalo lonke uhlelo lwegesi yasekhaya.

2. Ivalvu yegatsha: isetshenziselwa ukuhlukanisa ipayipi legesi libe amagatsha ahlukene.Ungakhetha ukuvula noma ukuvala amagatsha athile njengoba kudingeka ukuze kube lula ukulawula ukutholakala kwegesi ezindaweni ezahlukene.

3. I-valve yangaphakathi yemitha yegesi: Ifakwe phambi kwemitha yegesi, isetshenziselwa ukuqapha nokukala ukusetshenziswa kwegesi, futhi ingasetshenziselwa ukuvala ukunikezwa kwegesi.

4. I-valve yokuzivala yeGas Pipeline: Ivamise ukufakwa ekugcineni kwepayipi legesi, exhunywe kumshini wegesi ngepayipi legesi elikhethekile.Ziyisithiyo sokuphepha phambi kwepayipi nesitofu.Ngokuvamile, bane-valve yabo yezandla esetshenziswa njenge-valve yangaphambili yesithando somlilo.Ine-over-voltage, i-under-voltage kanye nemisebenzi yokuvikela enqamulelayo ye-othomathikhi eyedlule.

5. I-Valve phambi kwesitofu: Ngokuvamile ifakwe ekugcineni kwepayipi lensimbi nangaphambi kwepayipi, isetshenziselwa ukulawula ukungena komoya wepayipi legesi ku-hose nesitofu.Ngemuva kokusebenzisa igesi ebusuku noma ngaphambi kokuphuma isikhathi eside, abasebenzisi kufanele bavale i-valve phambi kwesithando somlilo ukuze baqinisekise ukuphepha kwegesi yasendlini.

Umsebenzi wala ma-valve ukuqinisekisa ukusebenza ngokuphephile kwesistimu yegesi yasekhaya nokuvimbela ukuvuza kwegesi nezingozi.Ukunikezwa nokunqanyulwa kwegesi kungenziwa ngokulawula ukuvulwa nokuvalwa kwe-valve, okwenza kube lula ukusebenza nokugcinwa kwemishini yegesi.
