Na usoro nke iji valves, ị nwere ike izute mmebi akara, ị maara ihe kpatara ya? Nke a bụ ihe ị ga-ekwu banyere ya. Akara ahụ na-ekere òkè n'ịbelata na ijikọ, na-edozi na nkesa, nkewa na ịgwakọta mgbasa ozi na ọwa valvụ, n'ihi ya, a na-etinyekarị ihe mkpuchi ahụ na corrosion, mmebi, na-eyi na ngwa ngwa mebie site na ọkara.

Ihe kpatara mmebi nke elu akara akara bụ mmebi nke mmadụ mere na mmebi eke. A na-akpata mmebi nke mmadụ site na ihe ndị dị ka imewe adịghị mma, mmepụta ihe na-adịghị mma, nhọrọ na-ekwesịghị ekwesị nke ihe, na ntinye na-ezighị ezi. Nbibi eke bụ iyi nke valvụ n'okpuru ọnọdụ ọrụ nkịtị, ọ bụkwa mmebi nke mmebi ahụ na-apụghị izere ezere na mmebi nke ọkara n'elu akara.

Enwere ike ichikota ihe kpatara mmebi okike dika ndi a:

1. Akara nhazi nhazi elu adịghị mma

Ọ bụrụ na enwere ntụpọ dị ka mgbawa, pores na ballast n'elu mkpuchi mkpuchi, ọ na-eme ya site na nhọrọ na-ezighị ezi nke nchacha ọkụ na ikpo ọkụ na-arụ ọrụ na-adịghị mma na usoro nke surfacing na ọgwụgwọ okpomọkụ. Ihe siri ikeess nke mkpuchi mkpuchi dị oke elu ma ọ bụ dị ala, nke a na-eme site na nhọrọ ihe na-ezighị ezi ma ọ bụ ọgwụgwọ okpomọkụ na-ekwesịghị ekwesị. A na-ebute isi ike na-enweghị isi na nguzogide na-enweghị corrosion nke elu mkpuchi ahụ site na ịfụ metal ala n'elu n'oge usoro ịgbado ọkụ na-agbado ma na-edozi ihe ngwakọta alloy nke elu mkpuchi ahụ. N'ezie, enwere ike ịnwe okwu nhazi.

2. Mmebi kpatara nhọrọ na-ezighi ezi na arụ ọrụ adịghị mma

Isi ihe na-arụ ọrụ bụ na ahọrọghị valvụ ahụ dịka ọnọdụ ọrụ si dị, a na-ejikwa valvụ a na-ebipụ dị ka valvụ strottle, na-eme ka nrụgide mmechi dị ukwuu dị ukwuu na ngwa ngwa ma ọ bụ lax na-emechi, nke mere na mkpuchi mkpuchi na-emebi. na eyi.Nrụnye na-ezighị ezi na nlekọta na-adịghị mma na-eduga n'ịrụ ọrụ na-adịghị mma nke mkpuchi mkpuchi, na valvụ ahụ na-arụ ọrụ na ọrịa, na-emebisị elu akara.

3. Chemical corrosion nke ọkara

Mgbe ndị na-ajụ gburugburu gburugburu akara mkpuchi adịghị emepụta ugbu a, medium na-arụ ọrụ ozugbo n'elu mkpuchi nke kemịkalụ ma na-emebi ihe mkpuchi ahụ.Electrochemical corrosion, sealing surface contact with each other, sealing surface contact with the emechi ahu na valvụ ahụ, nakwa dị ka ịta ihe dị iche nke na-ajụ, oxygen ịta ọdịiche na ihe ndị ọzọ, ga-emepụta nwere ike dị iche iche, electrochemical corrosion, n'ihi na anode n'akụkụ nke sealing elu bụ corroded.

4. Mbipu nke ọkara

Ọ bụ n'ihi na-eyi, ozize na cavitation nke akara n'elu mgbe ọkara aga. Na a ụfọdụ ọsọ, na sere n'elu ezi ahụ na-ajụ mmetụta akara n'elu, na-eme ka obodo mmebi; oke ọsọ na-eru mdium na-asachapụ ozugbo n'elu akara, na-akpata mmebi mpaghara; mgbe ọkara agwakọtara eruba na vaporization mpaghara, afụ na-agbawa ma na-emetụta elu akara, na-akpata mmebi mpaghara. Mbibi nke ọkara jikọtara ya na omume ọzọ nke corrosion kemịkalụ ga-agbapụta nke ọma n'elu akara.

5. Mechanical mmebi

A ga-emebi elu mkpuchi mkpuchi na usoro mmeghe na imechi, dị otú ahụọchihịa, ịkụ aka, ịpịa na ihe ndị ọzọ. N'etiti oghere abụọ a na-emechi emechi, atom na-abanye n'ime ibe ha n'okpuru omume nke okpomọkụ dị elu na nrụgide dị elu, na-akpata adhesion. Mgbe ebe abụọ a na-emechi emechi na-agagharị na ibe ha, adhesion dị mfe ịbịaru. Ka elu nke ịdị elu nke elu akara akara, ka ihe omume a na-adị mfe karị. N'oge usoro mmechi nke valvụ na diski valvụ na usoro ịlaghachi n'oche ahụ, a ga-emerụ ihe mkpuchi ahụ ma kpoo ya, na-eme ka uwe ma ọ bụ ntinye mpaghara n'elu akara.

6. Mmebi ike ọgwụgwụ

N'ime ogologo oge eji akara akara, n'okpuru ọrụ nke ibu ọzọ, ihe mkpuchi ahụ ga-emepụta ike ọgwụgwụ, mgbawa na ịkwapụ oyi akwa. Rubber na plastik mgbe ejiri ogologo oge mee ihe, dị mfe ịmepụta ihe ịka nká, na-akpata arụ ọrụ adịghị mma.

Site na nyocha nke dị n'elu nke mmebi ihe na-akpata ihe mkpuchi mkpuchi ahụ, a pụrụ ịhụ na iji mee ka mma na ndụ ọrụ nke valvụ ahụ na-ekpuchi elu, a ghaghị ịhọrọ ihe ndị dị n'elu ihe mkpuchi kwesịrị ekwesị, nhazi nke ọma na usoro nhazi.
