Nkwupụta maka “Ikike zuru oke” nke klaasị 1 Injinia Ọkụ na 2018: Nwụnye Valve

1) Achọrọ nwụnye:

① The valves eji na ọkpọkọ ngwakọta ụfụfụ gụnyere akwụkwọ ntuziaka, eletriki, pneumatic na hydraulic valves. A na-ejikarị atọ nke ikpeazụ eme ihe na pipeline buru ibu, ma ọ bụ njikwa anya na akpaaka. Ha nwere ụkpụrụ nke ha. Ihe valvụ ndị a na-eji na pipeline ngwakọta nke ụfụfụ kwesịrị ịbụ Maka ntinye dị ka ụkpụrụ ndị dị mkpa si dị, valvụ ahụ ga-enwerịrị oghere na akara mmechi doro anya.

②Valves nwere njikwa anya na ọrụ njikwa akpaka ga-etinyerịrị dịka ihe achọrọ; mgbe etinyere ha na mgbawa na gburugburu ihe egwu ọkụ, ha ga-adịrịrị n'ụkpụrụ mba dị ugbu a “Electrical Installation Engineering Explosion and Fire Hazardous Environment Electric Installation Construction and Acceptance Specification 》(GB50257-1996).

③ The ígwè ebili azuokokoosisi valvụ na valvụ elele arụnyere na ebe ebe ụfụfụ pipeline nke submerged jet na ọkara submerged jet ụfụfụ ọkụ na-enyụ usoro na-abanye na nchekwa tank mkpa ka etinyere n'ahịrị, na ntụziaka akara na valvụ ego ga-adịrịrị. na-ekwekọ n'ụzọ ntụgharị nke ụfụfụ. Ma ọ bụghị ya, ụfụfụ ahụ enweghị ike ịbanye na tankị nchekwa, ma onye na-ahụ maka nchekwa na nchekwa nwere ike ịlaghachi na pipeline, na-akpata ihe mberede ndị ọzọ.

④ Ihe nrụnye nrụgide, ihe nzacha ọkpọkọ, na valvụ njikwa arụnyere na ọkpọkọ ọkpọkọ mmiri na-ekpo ọkụ na-abanye n'ime oghere nke ihe na-emepụta ụfụfụ dị elu kwesịrị itinye ya na ọkpọkọ alaka kwụ ọtọ.

⑤ The akpaka iyuzucha valvụ etinyere na ụfụfụ agwakọta pipeline mmiri kwesịrị ka etinyere na kwụ ọtọ mgbe usoro ahụ gafere ule nrụgide na flushing. valvụ na-ekpochapụ akpaka nke edobere na ọkpọkọ mmiri agwakọta ụfụfụ bụ ngwaahịa pụrụ iche nke nwere ike ịgbanye gas na pipeline ozugbo. Mgbe ọkpọkọ ahụ jupụtara na ngwakọta ụfụfụ (ma ọ bụ jupụta na mmiri n'oge nkwụsịtụ), gas dị na pipeline ga-eme ka ọ bụrụ nke a na-ebuga n'ebe kachasị elu ma ọ bụ ebe ikpeazụ na-ezukọ nke gas na pipeline. valvụ nke na-ekpochapụ akpaka nwere ike ịpụpụ ikuku ndị a na-akpaghị aka. Mgbe pipeline valvụ ahụ ga-emechi na-akpaghị aka mgbe ejuchara ya na mmiri mmiri. Ntinye kwụ ọtọ nke valvụ iyuzucha bụ ihe achọrọ nke usoro ngwaahịa. A na-eme nrụnye ahụ mgbe usoro ahụ gafechara ule nrụgide na ịgbanye iji gbochie mgbochi ma na-emetụta iyuzucha.

⑥ A ga-etinye valvụ na-achịkwa na ọkpọkọ mmiri mmiri agwakọta na-ejikọta ya na ngwaọrụ na-emepụta ụfụfụ n'èzí ihe nrịbama nrụgide n'èzí ọkụ ọkụ, na-egosi oghere na mmechi doro anya; mgbe ụfụfụ agwakọtara pipeline na-edozi n'ala, a na-achịkwa nrụnye elu nke valvụ nchịkwa n'ozuzu ya na N'etiti 1.1 na 1.5m, mgbe a na-eji valvụ njikwa nkedo na mpaghara ebe okpomọkụ ikuku dị 0 ℃ na n'okpuru, ma ọ bụrụ na ọ dị mkpa. a na-etinye ọkpọkọ n'elu ala, a ga-etinye valvụ nchịkwa nke nkedo na ịrị elu; ọ bụrụ na a na-eli ọkpọkọ n'ime ala ma ọ bụ tinye ya na trenchi, nkedo ígwè a ga-etinye valvụ nchịkwa na valvụ nke ọma ma ọ bụ trenchi, a ga-emekwa ihe mgbochi na-ekpo ọkụ.

⑦ Mgbe a na-ekpochapụ ụfụfụ ọkụ ọkụ na-ekpo ọkụ na ebe nchekwa tank nwekwara ọrụ nke usoro nhazi nke ọkara, ọ dị mkpa iji wụnye nkwonkwo ọkpọkọ na valvụ nchịkwa na mkpuchi mkpuchi na ụfụfụ gwakọtara pipeline mmiri n'èzí ọkụ ọkụ ka. ikwado gwongworo ọkụ ma ọ bụ ọgụ ọkụ mkpanaka ndị ọzọ Ngwa na-ejikọta ya na ngwa ọkụ na-ekpo ọkụ na-ekpo ọkụ na ebe nchekwa tank.

⑧ The echichi elu nke valvụ akara set na ụfụfụ agwakọta mmiri riser bụ n'ozuzu n'etiti 1.1 na 1.5m, na ihe doro anya oghere na mmechi akara kwesịrị ịtọ; mgbe ịdị elu nrụnye nke valvụ njikwa karịrị 1.8m, ikpo okwu na-arụ ọrụ ma ọ bụ ọrụ kwesịrị ịtọ stool.

⑨ Ọkpụkpọ nlọghachi na valvụ njikwa arụnyere na ọkpọkọ mgbapụta nke mgbapụta ọkụ ga-enwerịrị ihe achọrọ imewe. Ogologo nrụnye nke valvụ nchịkwa na-adịkarị n'etiti 0.6 na 1.2m.

⑩ Ekwesịrị itinye valvụ ikuku ikuku na pipeline na ebe kachasị ala iji mee ka mkpochapụ kachasị nke mmiri mmiri dị na pipeline.

2) Usoro nyocha:A na-ahụ ihe ① na ② ma na-enyocha ya dịka ihe achọrọ nke ụkpụrụ ndị dị mkpa, na nlele ndị ọzọ na nyocha ndị ọchịchị.
