Fire esangweni: zilwane alandisa izici zedivayisi

Ukuze umlilo ukucindezelwa kudinga lonke uhlelo eyayakhiwa hydrant, amapayipi amanzi, valve nezinye izinhlobo izakhi. Lezi amadivayisi uvumele ukuphakela amanzi iphuzu ukuthungela ngqo. Ngiphakathi uhlelo zokucisha umlilo ayiphelele ngaphandle valve eliphezulu lapho valve umlilo. Cabanga ngalokho izinhlobo zikhona, ukungaboni ngaso linye kwabo futhi izinzuzo usebenzisa.

izenzo normative

Kuzo zonke izindaba eziphathelene ukuvikelwa umlilo izinhlelo, imigomo senzeka ebhekisela madokumende alandelayo:

• NPB 154-2000. Lokhu isiqondiso lembula yonke imininingwane mayelana inqubo umlilo, ama-valve, umlilo hydrants. Iphinde ulawula lobuchwepheshe ingxenye: nezidingo zokuphepha kanye nezindlela imishini yokuhlola.
• GOST P 53278-2009. idokhumenti Langaphambilini izithinta Standard njengoba idokhumenti eziyisisekelo, esihlinzeka incazelo esinembile yamanani zokulawula ezithile.
• UMthetho Federal №123. Lo mthetho ulawula isimo zomthetho uma umlilo, kanye izinyathelo ukuvimbela it.

Lezi ziqondiso elawula zonke izindawo, kusuka ukukhiqizwa valve ngaphambi ukusebenzisa futhi test.

Kuyini lokhu?

Fire esangweni (aka valve) iyingxenye crane. Ogibele ngaphakathi kohlelo alondoloze nemithombo yamanzi umlilo zokucisha uketshezi noma igesi lokushisa ku-50 ° C. Omunye ekupheleni lo mkhiqizo ngeke kube ngendlela emikhonweni, kanti eyesibili - tsapkovy (owesilisa) for screwing the yokuxhuma elihlangana ikhanda. Ngu design, umlilo valve akahlukile nozakwabo ezivamile. Umehluko - kuphela ububanzi nezezinto ezibonakalayo. Ngo design yabo, banalo handwheel bushing nokupakisha indlala ikhanda umzimba, induku threaded, ukuzehlukanisa INGAPHANDLE gasket.

izinhlobo

izinhlobo eziningana ungabahlukanisa ngokuvumelana nezimfuno ehlukahlukene:

• Ngokusho uhlobo ukufakwa - siteshi, udonga.
• Ngu ebhekisela elingaphandle sikebhe isakhiwo - engela (90 ° noma 125 °), nokuxhumana, ngokusebenzisa-ukugeleza.
• Ngu umsebenzi - wavala, ivale-off futhi elawula ekhethekile.
• Indaba - yensimbi, nethusi.
• Njengoba ubukhulu yangaphakathi - 50 mm noma 65 mm.
• Ngokusho uhlobo uxhumano - elihlangana / bamba, bamba / hoe. Hoe valve umlilo hose ivumela uxhumano ipayipi lamanzi (umlilo hose ferrule).

A ezihlukahlukene ngeengaba akuphazamisi izinga eziyisisekelo kufaneleka - nokwethenjelwa.

Okudingekayo ukuze valve

Kunezindlela eziningana izimfuneko valve umlilo:

• uphawu imikhiqizo kanye compounds;
• NW - kusuka 40 kuya 65 mm;
• ingcindezi ukusebenza uma amanzi - hhayi ngaphansi kuka-1 MPA;
• ingcindezi ezisebenza ingaphansi valve;
• izinga lokushisa lokusebenza akumele leqe 50 ° C;
• inombolo linemibhikisho ngaphambi kokuvula - 4 kuya 6, kuye ngokuthi lelo vesi okuzisholo;
• Ligcina uthi lokuphotha luzungeza Ukujikeleza - kwesokudla;
• crimping saziso amahora 12 ngaphambi ukudayiswa.

Zonke lezi zimfuneko kunendlela ngokushesha nomlilo izimo ukuqala isimiso isinyathelo izimo ezimbi kakhulu.

ukukhishwa impahla

Fire umphini Yenziwe cast iron and zethusi. Lokhu kungenxa yokuthi izihloko ezinjalo kufanele ifa amandla kanye nokwethembeka. Iron, ithusi, nasesikhundleni izici ezinjalo ziyahlukahluka, okungukuthi anticorrosive, ukuqina kanye ikhono lokubekezelela ingcindezi eliphezulu ohlelweni. Lezi izindawo avumele ukusetshenziswa kwemikhiqizo enjalo isikhathi eside.

wokugubha

izakhiwo Crane ziboniswa hhayi kuphela incwadi, izimpawu digital, kodwa futhi umbala uhlamvu nomzimba imidwebo. I Ukumaka ngendlela isicelo ngumuntu ekubunjweni futhi kufanele siphathe idatha elandelayo:

• enobubanzi obungu;
• ingcindezi okuzisholo;
• bezinhlamvu impahla;
• lokuhweba kanye / noma igama nomkhiqizi;
• isiqondiso medium ezisebenza;
• Unyaka;
• umcibisholo-pointer esiqondisweni imvelo yokusebenza;
• ukuqokwa gaskets ngoba flange ukubekwa uphawu nokunye. d.

Imihlobo asele ka Ukumaka ngendlela isicelo ngokuhambisana nezimfuneko ezingokomthetho neziqondiso.

Umbala esephepheni wembulela impahla kusukela okwakwenza izindlu:

• Black - Mpunga, oluthambile, ductile Castings yensimbi;
• grey - carbon steel;
• blue - ingxubevange steel;
• blue - ingxubevange okusezingeni eliphezulu steel, ukugqwala ukumelana futhi Alloys ukushisa ukumelana.

Njengoba singabona, valve nomlilo izici zabo adalule ngokugcwele kophawu.

ukufakwa kanye nokugcinwa izici

Imihlobo ehlukeneko design ivumela valve ye hydrant umlilo kunoma isiphi isikhundla. Okunqatshelwe ukufakwa ligcina uthi lokuphotha luzungeza phansi. Ezimweni umlilo, umsebenzi ngamanzi ohlelweni lokuthengwa kwempahla kumele zaneliswe nguzulu futhi kulula. Esimeni esiphuthumayo, njalo ukubalwa yesibili, ngakho-valve kumele kuvulwe 4-6 iphendula. imiklamo Modern zikuvumela ukwenza izenzo ezinjalo ngaphandle iziyisikhombisa ezengeziwe. Lapho uhlelo lokukhuphula kufanele libukwe ukuvuza. Uma ufaka valve phezu uxhumano komsele kuthiwa some futhi uphawu indlala gasket. Ngaphambi kokufaka, igemfe zigezwe ngokucophelela nithuntuthe inhlabathi nesihlabathi.

Hardware Izidingo:

• Ungakwazi ukufaka valve usebenzisa ikhanda elihlangana.
• Ngezinye ukwehluleka (ukuwohloka) kophawu indlala-ke esikhundleni.
• I stock kukhonjelwe Lubrication gqwa.
• Avamile imishini Test.
• Ekupheleni impilo eshalofini umshini owenza adiliza wabiza kabusha.
• Impilo inkonzo valve incike ukufakwa ababulawa kahle futhi uhlale umuhle.

Shut-off valve umlilo - omunye wemizila ebaluleke kakhulu ohlelweni amadivayisi umlilo-elwa. On izinga layo kanye ukufakwa efanele kuncike ijubane kanye nokwenzeka ukusetshenziswa kwayo ezimweni eziphuthumayo. Futhi lokhu kuncike umuntfu lakhetsa kuphila ngato. Ngakho-ke, amabhizinisi avinjelwa ngokuqinile ukusetshenziswa imishini umlilo elwa, hhayi ohambelana imibhalo normative.

Uma ukuthenga idivayisi ezifana valve, kufanele ucele isitifiketi sokuhambisana. Nakani mshini phezu ngalo sisetshenziswa kahle futhi ukuthi lwemininingwane yobuchwepheshe edingekayo. Ngokuphazima umcimbi akufanele bathathe imikhiqizo Lokudabuka ezingabazisayo. Abanaso kuhluke izinga elifanele nokwethembeka. Londoloza mikhiqizo akudingekile, bancike ngqo empilweni kanye nempilo yabantu.
