Ukuba luhlobo lwamandla kubomi obunobuhlobo kokusingqongileyo, igesi isetyenziswa kwindawo ebanzi njengezindlu kunye neendawo zokutyela. Ngelixa ugqabhuko-dubulo luya kwenzeka ukuba ukuvuza kwerhasi kuhlangana nomlilo, okanye ngokusebenza okungafanelekanga, kwaye iziphumo ziya kuba zibi. Nangona ukukhuthazwa kwerhasi yesizwe kuye kwanda kwaye izinga lokungena liphucula, inani leengozi ezibangelwa yigesi lisephezulu. Kwisiqingatha sokuqala sonyaka we-2021, kukho iingozi zegesi ezingama-544 eziye zenzeka kwilizwe lonke, zahlulwa kumaphondo angama-31 kunye nezixeko ezingama-215, kubandakanywa ukuqhuma okukhulu kwe-1 kunye nokulimala kwe-71 kunye nokulimala kwe-412, ngokutsho kweNgxelo yoHlalutyo lweNgozi yeGasi yeSizwe epapashwe nguLawulo loKhuseleko. IKomiti ye-China City Gas Association. Ingxaki yombhobho yeyona nto ibangela ezi ngozi. Imiba eqhelekileyo kukuwa, ukonakaliswa kokuguga, ukulunywa zizilwanyana kumbhobho werhasi, ukutshisa ngokuqhubekayo okomileyo kwesitovu serhasi kubangela umlilo kunye nogqabhuko-dubulo, kunye nokuvuza okubangelwa kukudityaniswa kwangasese kunye nokuguqulwa kwemibhobho yegesi.

Ukunciphisa ukwenzeka kweengozi zegesi, kunye nokukhusela ubomi babantu kunye nepropathi; I-Chengdu Zhicheng Technology Co. LTD iququzelele iqela eliqeqeshiweyo le-R & D ukuba lizenzele ngokuzimeleyo umbhobho wegesi ozivalayo wevalve yokhuseleko, kunye neteknoloji yodidi lokuqala kunye nemowudi yokuvelisa ehlakaniphile. Olu hlobo lwevalvu yokhuseleko lwegesi [ ]'s rated work pressure 2Kpa, over-pressure for self-close is 8Kpa±2Kpa, under-pressure for self-close is 8Kpa±2Kpa, kunye nokuphuphumayo kokuzivala ≦ Amaxesha ama-2 okuhamba okulinganiselwe. Ukusebenza kwevalve yekhitshi ezivalayo idibana nemigangatho yeCJ/T447-2014.
