Kwinkqubo yegesi yendalo ekhaya, kukho iivalvu zegesi ezimbalwa.Zifakwe kwiindawo ezahlukeneyo kwaye zidlala imisebenzi eyahlukeneyo.Siza kuzichaza ngokwahlukeneyo.

1. Ivalve yasekhaya: ngokuqhelekileyo ibekwe apho umbhobho werhasi ungena endlwini, esetyenziselwa ukulawula ukuvulwa nokuvalwa kwayo yonke inkqubo yegesi yasekhaya.

2. Ivalve yesebe: isetyenziselwa ukwahlula umbhobho werhasi ube ngamasebe ahlukeneyo.Unokukhetha ukuvula okanye ukuvala amasebe athile njengoko kuyimfuneko ukuze kube lula ukulawula ukunikezelwa kwegesi kwiindawo ezahlukeneyo.

3. I-valve yangaphakathi yemitha yegesi: Ifakwe phambi kwemitha yegesi, isetyenziselwa ukubeka iliso kunye nokulinganisa ukusetyenziswa kwegesi, kwaye ingasetyenziselwa ukuvala ukunikezelwa kwegesi.

4. I-valve yokuzivala ye-Gas Pipeline: Ngokuqhelekileyo ifakwe ekupheleni kombhobho wegesi, exhunywe kwisixhobo segesi ngokusebenzisa umbhobho okhethekileyo wegesi.Zingumqobo wokhuseleko phambi kombhobho kunye nesitovu.Ngokuqhelekileyo, banevalve yabo yezandla esetyenziswa njengevalve yangaphambili yesithando somlilo.Ine-over-voltage, i-under-voltage kunye ne-over-current-current cut-off yokukhusela imisebenzi.

5. I-valve phambi kwesitofu: Ngokuqhelekileyo ifakwe ekupheleni kombhobho wensimbi kunye naphambi kombhobho, isetyenziselwa ukulawula umoya wepayipi yegesi kwi-hose kunye nesitofu.Emva kokusebenzisa igesi ebusuku okanye ngaphambi kokuphuma ixesha elide, abasebenzisi kufuneka bavale i-valve phambi kwesithando somlilo ukuqinisekisa ukhuseleko lwegesi yangaphakathi.

Umsebenzi wezi zivalo kukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo yegesi yasekhaya kunye nokuthintela ukuvuza kwegesi kunye neengozi.Ukunikezelwa kunye nokunqunyulwa kwegesi kunokuqondwa ngokulawula ukuvulwa nokuvalwa kwe-valve, eququzelela ukusebenza kunye nokugcinwa kwezixhobo zegesi.
