1) Iimfuno zofakelo:
① Iivalvu ezisetyenziswa kumbhobho womxube wogwebu ziquka iivalufa zemanyuwali, zombane, zomoya kunye nehydraulic. Ezi zintathu zokugqibela zisetyenziswa kakhulu kwimibhobho yobubanzi obukhulu, okanye ulawulo olukude kunye noluzenzekelayo. Banemigangatho yabo. Iivalvu ezisetyenziswe kumbhobho womxube we-foam kufuneka zibe Ufakelo ngokwemigangatho efanelekileyo, ivalve kufuneka ibe neempawu ezicacileyo zokuvula nokuvala.
②Iivalvu ezinolawulo olukude kunye nemisebenzi yolawulo oluzenzekelayo kufuneka ifakwe ngokuhambelana neemfuno zoyilo; xa zifakwe kwindawo yogqabhuko-dubulo kunye nengozi yomlilo, kufuneka zihambelane nomgangatho wangoku wesizwe “Ukuqhuma koBunjineli boFakelo loMbane kunye neNdawo enobungozi yoMlilo yokuFakelo loFakelo loMbane uKwakha kunye neNkcazelo yoKwamkelwa 》(GB50257-1996).
③Ivalve yentsimbi enyukayo yesango kunye nevalve yokukhangela efakwe kwindawo apho umbhobho wogwebu wejethi entywiliselwayo kunye nejethi entywilayo yejethi yokucima umlilo ingena kwitanki yokugcina kufuneka ifakwe ngokuthe tye, kwaye isalathiso esiphawulwe kwivalve yokutshekisha kufuneka ihambelana nesikhokelo sokuhamba kwe-foam. Ngaphandle koko, i-foam ayikwazi ukungena kwi-tank yokugcina, kodwa i-medium kwi-tank yokugcina inokubuyela emva kwipayipi, ibangele iingozi ezininzi.
④Igeyiji yoxinzelelo, isihluzo sombhobho, kunye nevalve yolawulo efakwe kumbhobho wolwelo oxutywe nogwebu kwindawo yokungena kwijenereyitha yogwebu eyandiswa kakhulu kufuneka ifakwe ngokubanzi kumbhobho wesebe othe tye.
⑤Ivalve yokukhupha ezenzekelayo esetwe kumbhobho wolwelo oxutywe amagwebu kufuneka ifakwe ngokuthe nkqo emva kokuba inkqubo iphumelele uvavanyo loxinzelelo kunye nokugungxulwa. Ivalve yokukhupha ngokuzenzekelayo iseti kumbhobho we-foam oxutywe nolwelo yimveliso ekhethekileyo enokuthi ikhuphe ngokuzenzekelayo igesi kumbhobho. Xa umbhobho uzaliswe ngumxube wogwebu (okanye uzaliswe ngamanzi ngexesha lokulungiswa kweempazamo), irhasi ekwimibhobho iya kuqhutywa ngokwendalo iye kwelona ndawo iphezulu okanye kwindawo yokugqibela yokuqokelelwa kwerhasi kumbhobho. Ivalve yokukhupha i-automatic inokukhupha ezi gesi ngokuzenzekelayo. Xa umbhobho uya kuzivala ngokuzenzekelayo emva kokuzaliswa ngolwelo. Ukufakwa ngokuthe nkqo kwevalve yokukhupha iyimfuneko yesakhiwo semveliso. Ufakelo lwenziwa emva kokuba inkqubo iphumelele uvavanyo loxinzelelo kunye nokugungxula ukukhusela ukuvala kunye nokuchaphazela ukukhupha.
⑥Ivalve yokulawula kumbhobho wolwelo oxutywe ugwebu odityaniswe kwisixhobo sokuvelisa ugwebu kufuneka ifakwe ngaphandle kojongano lwegeyiji yoxinzelelo ngaphandle kwedikhi yomlilo, eneempawu ezicacileyo zokuvula nokuvala; xa umbhobho wolwelo oluxutywe nogwebu usete emhlabeni, umphakamo wofakelo lwevalve yolawulo kulawulwa ngokubanzi Phakathi kwe-1.1 kunye ne-1.5m, xa ivalve yolawulo yentsimbi isetyenziswa kwiindawo apho ubushushu obukuleyo yi-0℃ nangaphantsi, ukuba umbhobho ufakwe emhlabeni, ivalve yokulawula intsimbi kufuneka ifakwe kwindawo yokunyuka; ukuba umbhobho ungcwatywe emhlabeni okanye ufakwe kumsele, intsimbi etyhidiweyo Ivalve yokulawula kufuneka ifakwe kwivalve emseleni okanye kumsele, kwaye amanyathelo achasene nomkhenkce kufuneka athathwe.
⑦ Xa isixokelelwano sokucima umlilo esinegwebu esisisigxina kwindawo yokugcina itanki inomsebenzi wenkqubo engaguqukiyo, kuyafuneka ukuba kufakwe umbhobho odityanisiweyo onevalve yokulawula kunye nesigqubuthelo esixineneyo kumbhobho wolwelo oluxutywe nogwebu ngaphandle kwedike yomlilo ukuya. ukuququzelela iilori zomlilo okanye enye i-mobile fire fighter Isixhobo sixhunyiwe kwisixhobo sokucima umlilo esisisigxina se-foam kwindawo yokugcina itanki.
⑧ Umphakamo wofakelo wevalve yolawulo eseti kwi-foam exutyiweyo yokunyuka kolwelo ngokuqhelekileyo phakathi kwe-1.1 kunye ne-1.5m, kwaye uphawu olucacileyo lokuvula kunye nokuvala kufuneka lubekwe; xa ukuphakama kokufakwa kwevalve yokulawula kukhulu kune-1.8m, iqonga lokusebenza okanye ukusebenza kufuneka kubekwe isitulo.
⑨Umbhobho wokubuyisela onevalve yokulawula efakwe kumbhobho wokukhupha wempompo yomlilo kufuneka uhlangabezane neemfuno zoyilo. Ukuphakama kofakelo lwevalve yokulawula ngokuqhelekileyo phakathi kwe-0.6 kunye ne-1.2m.
⑩Ivalve yokukhupha umoya kumbhobho kufuneka ifakwe kweyona ndawo isezantsi ukuququzelela ukukhutshwa kolwelo kumbhobho.
2) Indlela yokuhlola:izinto ① kunye ② ziyajongwa kwaye zihlolwe ngokweemfuno zemigangatho efanelekileyo, kunye nolunye uqwalaselo kunye nokuhlolwa kweerula
