Nlekọta nke mmepụta nchekwa na nke mepere anya na-agụnye nsị mmanụ, ntanye mmiri, uzuoku uzuoku, ntanye anwụrụ ọkụ, ntanye ash, ntanye coal, ntapu uzuzu na ntanye gas, nke bụ ihe anyị na-akpọ "na-agba ọsọ, na-agbapụta, ntanye na ntanye". Taa, anyị na-achikota ụfọdụ mgbochi mgbochi nke "na-agba ọsọ, emitting, ntapu na ntapu" maka ntụle. M usoro mgbochi maka mmiri na uzuoku ntapu nke valves. 1. All valves ga-adị n'okpuru ọkwa dị iche iche nke ule hydrostatic mgbe ịbanye na osisi. 2. Valves nke kwesịrị ịkwasa maka mmezi ga-abụ ala. 3. N'ime usoro nhazi, ọ dị mkpa iji nlezianya lelee ma a na-agbakwunye nkwakọ ngwaahịa na ma ọ bụrụ na a na-eme ka gland ahụ sie ike. 4. Tupu ntinye nke valvụ, lelee ma enwere uzuzu, ájá, iron oxide na sundries ndị ọzọ n'ime valvụ ahụ. Ọ bụrụ na e nwere nke ọ bụla n'ime ihe ndị a dị n'elu, a ga-ehichapụrịrị tupu echichi. 5. All valves ga-onwem na gasket nke kwekọrọ na ọkwa tupu echichi. 6. Mgbe ị na-etinye ọnụ ụzọ flange ahụ, a ghaghị imechi ihe nkedo ahụ. Mgbe ị na-eme ka bolts flange dị ike, a ga-emesi ha ike n'akụkụ ntụzịaka n'aka nke ya. 7. N'ime usoro ntinye valvụ, a ghaghị itinye valvụ niile n'ụzọ ziri ezi dị ka usoro na nrụgide siri dị, machibido iwu na-enweghị usoro na ngwakọta. A ga-agụrịrị valvụ niile ma dekọọ dịka usoro ahụ si dị tupu echichi. II Akpachara anya maka mwepu nke coal awụfuru. 1. A ghaghị itinye flanges niile na ihe mkpuchi. 2. Ebe ndị na-agbapụta ntụ ntụ bụ valvụ coal na ntinye na ntinye nke pulverizer, onye na-eri nri, flange nke onye na-emepụta ihe, na akụkụ niile nwere njikọ flange. N'ihi nke a, a ga-enyocha akụkụ niile nke akụrụngwa nke ndị na-emepụta ihe niile na-adị njikere ịwụ ntụ ntụ, na ndị na-enweghị ihe mkpuchi ga-agbakwunye ugboro abụọ, a ga-agbatịkwa ihe nkedo. 3. A ga-eme usoro ndị a maka nkwụsị nke coal na-ekpo ọkụ na nkwụsị nke welded nke ọkpọkọ ọkpọkọ. 3.1 tupu ịgbado ọkụ, a ga-eji nlezianya na-ehichasị ebe a na-agbado ọkụ ka ọ bụrụ nke dara dara na oghere a chọrọ maka ịgbado ọkụ. 3.2 tupu nkwonkwo butt, a ga-edobe nchapụta nkwonkwo butt ma amachibidoro nkwonkwo mmanye nke ọma. A ghaghị iji ihe ịgbado ọkụ 3.3 mee ihe n'ụzọ ziri ezi, na preheating ga-emerịrị dị ka achọrọ na ihu igwe oyi. III Usoro mgbochi maka mwepu sistemu mmanụ na mpụta mmanụ. 1. N'oge ntinye nke pipeline mmanụ, nkwonkwo flange niile ma ọ bụ njikọ njikọ nke nwere eriri screw ga-enwerịrị ihe mkpuchi mmanụ na-eguzogide mmanụ ma ọ bụ pad asbestos na-eguzogide mmanụ. 2. Leakage ihe nke mmanụ usoro na-tumadi lekwasị flange na n'otu na eri, otú bolts ga-tightened evenly mgbe wụnye flange. Gbochie ntapu ma ọ bụ ntọhapụ. 3. N'ime usoro nzacha mmanụ, ndị ọrụ na-ahụ maka ọrụ ga-anọgide na-arụ ọrụ mgbe niile, a machibidoro iwu ịhapụ ọkwa ahụ ma gafere ọkwa ahụ. 4. Kwụsị mmanụ mmanụ tupu ị gbanwee akwụkwọ nzacha mmanụ. 5. Mgbe ị na-etinye ihe nzacha mmanụ nwa oge na-ejikọta ọkpọkọ (plastic transperent hose nke dị elu), a ghaghị ijikọta njikọ ahụ nke ọma na waya ndu iji gbochie mmanụ ahụ ịwụpụ mgbe mmanụ mmanụ na-agba ọsọ ogologo oge. IV. gbochie akụrụngwa na ọkpọkọ ọkpọkọ ka ọ ghara ịfụ ụfụfụ, na-agbapụta, na-agbapụta na ntanye, na usoro mgbochi ndị a: Maka flange sealing gasket n'elu 1.2.5mpa, a ga-eji gasket igwe na-efegharị ígwè. 2.1.0mpa-2.5mpa flange gasket ga-abụ asbestos gasket na-ese na ojii ndu ntụ ntụ. 3.1.0mpa mmiri pipeline flange gasket ga-abụ roba gasket na-ese na nwa ndu ntụ ntụ. 4. Ngwunye nke mgbapụta mmiri ga-abụ ngwugwu ihe mejupụtara Teflon. 5. A ga-atụgharị eriri asbestos nke a na-eji na-emechi akụkụ nke anwụrụ ọkụ na ikuku coal pipes ma tinye ya na nkwonkwo nke ọma n'otu oge. A machibidoro iwu ịgbakwụnye ya n'ike ka emechara skru. V. A ga-eme usoro ndị a iji kpochapụ nkwụsị nke ime nke valvụ: (a ga-eme ihe ndị a iji gbochie nkwụsị nke valve) 1. Wụnye pipeline, hichaa ọnụ ọgụgụ ígwè oxide na mgbidi dị n'ime nke pipeline. na-enweghị ihe ọ bụla, ma hụ na mgbidi dị n'ime nke pipeline dị ọcha. 2. Gbaa mbọ hụ na valves na-abanye na saịtị ahụ ga-abụrịrị n'okpuru ule 100% hydrostatic. 3. A ga-ekpochapụ valvụ niile (ma e wezụga valvụ ntinye) maka nyocha, ichikota na nrụzi, na ndekọ na akara ga-eme ka ịchọta ya. A ga-edepụta valvụ dị mkpa n'ụzọ zuru ezu maka nnabata nke abụọ, iji mezuo ihe achọrọ nke "stamping, nyocha na ndekọ". ❖ ma ọ bụrụ na a tụfuru ya, n'ihi gịnị? (1) kọntaktị n'etiti oghere na mmechi akụkụ na abụọ akara n'elu oche valvụ; (2) ọnọdụ dabara adaba nke mbukọ, stem na igbe nri; (3) njikọ n'etiti valvụ ahụ na bonnet A na-akpọ ntanye mbụ nke ime ime, ya bụ, valvụ ahụ adịghị emechi emechi, nke ga-emetụta ikike nke valvụ ahụ iji bepụ ọkara. A na-akpọ ntanye abụọ ikpeazụ a na-akpọ ntanye, ya bụ, nke na-esi n'ime ya pụta n'èzí nke valvụ ahụ. Ntupu ga-akpata mfu ihe onwunwe, mmetọ gburugburu ebe obibi na ọbụna ihe mberede.
