Ugboro abụọ eccentric valvụ urukurubụba bụ na valvụ stem axis na-esi n'etiti efere nru ububa na etiti ahụ pụọ. Na ndabere nke okpukpu abụọ eccentricity, a na-agbanwe ụzọ akara nke valvụ eccentric eccentric urukurubụba ka ọ bụrụ cone nwere mmasị.

Ntụnyere nhazi:

Abụọ abụọ eccentric urukurubụba valvụ na okpukpu atọ eccentric urukurubụba valvụ nwere ike ime ka efere nru ububa ngwa ngwa hapụ oche valvụ mgbe e meghere ya, kpochapụ oke extrusion na-enweghị isi na ikpochapụ n'etiti efere nru ububa na oche valvụ, belata nkwụsị nke mmeghe, belata uwe ma melite ndụ ọrụ nke oche valve.

Ntụnyere ihe:

Akụkụ bụ isi nrụgide nke valvụ eccentric nru ububa okpukpu abụọ bụ nke ígwè ductile, na akụkụ nrụgide nke valvụ eccentric nru ububa atọ bụ nke nkedo ígwè. Ike nke ígwè ductile na nkedo ígwè bụ ihe atụnyere. Iron ductile nwere ike mkpụrụ dị elu, yana ike mkpụrụ dị ala nke 310mpa, ebe ike nke nkedo nchara bụ naanị 230MPa. N'ọtụtụ ngwa ime obodo, dị ka mmiri, mmiri nnu, uzuoku, wdg, nguzogide corrosion na oxidation nke ígwè ductile dị mma karịa nke nkedo ígwè. N'ihi spheroidal graphite microstructure nke ductile iron, ductile iron dị mma karịa nkedo ígwè na ibelata vibration, ya mere ọ na-eme ka ọ dịkwuo mma iji belata nrụgide.

Ntụnyere mmetụta akara:

valvụ nru ububa abụọ eccentric na-anakwere oche mgbanaka okirikiri na na-ese n'elu mmiri. N'okpuru nrụgide dị mma, nchapụta nke ntachi obi na-arụ ọrụ na nrụrụ nke valve shaft na nru ububa efere n'okpuru nrụgide ọkara na-eme ka elu elu nke nru ububa efere dịkwuo mma na njedebe nke oche valve. N'okpuru nrụgide na-adịghị mma, oche na-ese n'elu mmiri na-aga n'ihu nrụgide ọkara n'okpuru nrụgide ọkara, na-akwụghachi ụgwọ nke ọma site na nkwụsị nke machining na deformation nke valve shaft na nru ububa efere n'okpuru omume nke ọkara nrụgide, nke mere na-aghọta azụ akara.

Atọ eccentric siri ike akara urukurubụba valvụ na-anakwere oche valvụ conical na-achọsi ike yana mgbanaka akara ọtụtụ ọkwa. N'okpuru nrụgide dị mma, nkwụsị nke nkwụsị nke machining na-akpata na nrụrụ nke valve shaft na nru ububa efere n'okpuru nrụgide ọkara na-eme ka mgbanaka akara nke multi-level dabara adaba na elu nke oche valve, ma n'okpuru nrụgide ntụgharị, mgbanaka akara nke multi-larịị ga-adị anya site na mkpuchi mkpuchi nke oche valvụ, Ya mere, a pụghị imezu akara akara.
