Valve mmanụ akara bụ otu n'ime akụkụ dị mkpa nke otu valve engine, nke na-abanye na mmanụ ụgbọala na mmanụ engine na okpomọkụ dị elu.
Ya mere, ọ dị mkpa iji ihe ndị nwere oke ọkụ na mmanụ na-eguzogide mmanụ, na-emekarị nke fluororubber.
Akara valvụ stem na-enye ọnụ ọgụgụ mmanụ akọwapụtara na valvụ stem interface nke injin combustion dị n'ime iji mee ka mmanu ntụzịaka valvụ wee belata ikuku ikuku.
Ha dị maka mmanụ dizel na mmanụ ụgbọ ala na-enweghị nkwalite.
Na mgbakwunye na akara valvụ a na-ahụkarị, ihe anyị na-enye gụnyekwara akara valvụ maka injin nwere nrụgide dị elu na manifolds,
n'ihi chaja turbo ma ọ bụ maka brek iyuzucha na igwe azụmahịa.Na-egosipụta atụmatụ esemokwu dị ala,
akara ndị a na-eme ka ogo ikuku dị mma ma kwalite ọrụ engine site na iguzogide nrụgide dị elu na ọdụ ụgbọ mmiri na-ekpochapụ na ntinye nke engine.
N'agbanyeghị ụdị injin ahụ, anyị na-enye ụkpụrụ ọkọlọtọ abụọ nke akara valvụ stem:
Akara na-enweghị njikọ: na-emezu ọrụ nke nleba mmanụ

Ntinye na nnọchi nke akara mmanụ valvụ
(1) Nkwasa nzọụkwụ maka akara valvụ stem mmanụ:
① Wepu camshaft na hydraulic tappets, ma chekwaa ha ihu ala.
Kpachara anya ka ị ghara ịgbanwe tappet mgbe ị na-arụ ọrụ.Jiri mgbanaka plọg 3122B wepụ plọg ọkụ,
gbanwee piston nke cylinder kwekọrọ na etiti nwụrụ anwụ dị n'elu, wee kụchie eriri nrụgide VW653/3 n'ime oghere eriri ọkụ ọkụ.
② Wụnye ngwa mkpakọ mmiri 3362 n'elu isi cylinder nke nwere bolts, dị ka egosiri na eserese.
1. Gbanwee valvụ ndị dị mkpa na ọnọdụ ziri ezi, wee jikọọ eriri nrụgide na ikuku ikuku (na ikuku ikuku nke ọ dịkarịa ala 600kPa).
Jiri mkpara isi nke eri na atụgharị ka mpikota onu mmiri valvụ ala wee wepu mmiri ahụ.
③ Enwere ike wepụ ihe mgbochi mkpọchi valve site na ịpị obere valvụ na oche mmiri mmiri.Jiri ngwá ọrụ 3364 dọpụta akara valvụ stem mmanụ, dị ka egosiri na foto 2.
(2) Ntinye nke akara mmanụ valvụ.
Wụnye akpa rọba (A na eserese 3) n'elu valvụ ahụ iji gbochie mmebi nke akara mmanụ valvụ ọhụrụ ahụ.Jiri nwayọọ tinye akwa mmanụ injin na egbugbere ọnụ akara mmanụ.
Wụnye akara mmanụ (B na eserese 3) n'elu ngwá ọrụ 3365 wee jiri nwayọọ nwayọọ gbanye ya na ntuziaka valve.Ihe ncheta pụrụ iche:
Tupu ịwụnye valvụ oriri na iyuzucha, a ghaghị itinye akwa mmanụ engine na valvụ.
