Machining ntawm tes valve qia

Cov khoom siv ntawm tes tuav valve qia yog ua los ntawm cov tawv aluminium alloy uas yooj yim txiav. Vim hais tias lub valve pas nrig nto yog zawv zawg nyob rau hauv lub nplhaib sealing ncaj qha thaum lub sij hawm thim rov qab, qhov saum npoo xav tau siab hardness thiab qis roughness tus nqi. Yog li ntawd, lub valve qia nrog siab precision thiab qis nto roughness tus nqi yog tau los ntawm kev siv kaw CNC tshuab cuab tam thiab gemstone cutter. Tom qab tig, txhawm rau txhim kho qhov zoo ntawm qhov chaw thiab qhov nyuaj ntawm kev sib txhuam sealing nto ntawm lub valve qia, dov txheej txheem ntawm lub valve qia nto yog nqa tawm. Rolling yog txheej txheem dov rau dov tawv thiab du chais thiab hlau nto ntawm qia, thiab me ntsis yas deformation ntawm lub qia. Txoj cai ntawm dov yog qhia hauv qab no.

Qhov roughness ntawm lub dov valve qia tuaj yeem ncav cuag 0.1-0.8um daim iav nto, thiab hnav tsis kam thiab qaug zog lub zog ntawm cov dov valve qia yog txhim kho vim qhov hardening ntawm dov nto. Cov yam ntxwv ntawm cov txheej txheem dov saum toj no yog dhau ntawm cov txheej txheem txiav. Lub tshuab dov nrog nyiaj ntsuab tuaj yeem dov tsis yog tsuas yog lub cylindrical nto ntawm lub qia valve, tab sis kuj yog qhov kev hloov pauv ntawm cov qia ntawm lub valve. Tom qab tag nrho cov txheej txheem, nyuaj anodizing nto kev kho mob tau nqa tawm mus ntxiv txhim kho lub hardness thiab corrosion kuj ntawm lub valve qia thiab ua tau raws li cov kev ua tau zoo thiab yuav tsum tau ntawm lub valve qia.
