Peb feem ntau siv cov khoom siv hluav taws xob valve hauv ntau qhov chaw, tab sis peb tsis' tsis paub ntau txog cov khoom siv hluav taws xob valve. Yog li dab tsi yog cov txheej txheem sib dhos ntawm lub tshuab hluav taws xob valve? Cia's kawm ua ke tam sim no.
1. Kev npaj ua ntej sib dhos
Ua ntej sib sau ua ke valve, nws yog ib qhov tsim nyog los tshem tawm cov burrs tsim los ntawm machining thiab vuam residues, ntxuav thiab txiav fillers thiab gaskets.
2. ntxuav ntawm qhov chaw valve
Lub valve ntsia raws li kev tswj kav dej yuav tsum muaj cov kab noj hniav huv si. Hauv particular, li qub siv hauv nuclear fais fab, tshuaj, thiab khoom noj khoom haus kev lag luam muaj cov kev cai nruj dua ntawm kev huv ntawm lub valve kom huv si kom huv si ntawm nruab nrab thiab tsis txhob kis kab mob nruab nrab. Lub valve yuav tsum tau muab ntxuav ua ntej sib dhos, thiab txiav cov chips, cov roj seem seem, coolant thiab burrs, vuam slag thiab lwm yam av ntawm qhov chaw yuav tsum tau ntxuav thiab ntxuav. Lub valve feem ntau yog ntxuav los ntawm kev txau nrog dej alkaline lossis dej kub (krosene tuaj yeem siv los txhuam) lossis ntxuav hauv lub tshuab ntxuav ultrasonic. Tom qab cov khoom hauv av thiab polished, Zui tom qab ntxuav yog yuav tsum tau. Tom qab-Zui tu feem ntau yog los ntxuav lub sealing nto nrog roj av, ces qhuav nws nrog compressed cua thiab so nrog ib daim ntaub.
