Khoom nta ntawm lub teb chaws tus qauv viav vias kos valve
1. Cov khoom muaj cov qauv tsim nyog, txhim khu kev qha sealing, kev ua haujlwm zoo thiab zoo nkauj zoo nkauj;
2. Lub sealing nto yog overlaid nrog Co raws li cemented carbide, uas muaj kev hnav zoo, corrosion kuj, khawb tsis kam thiab kev pab lub neej ntev;
3. Ua nyob rau hauv tus pin ncej qauv txo cov to sab nraud thiab txhim khu kev qha hauv kev siv;
4. Thaum lub siab ntau dua los yog sib npaug rau 16.0mpa, tus kheej nruj sealing qauv yog saws nyob rau hauv nruab nrab chamber ntawm lub valve. Qhov siab dua qhov nruab nrab siab yog, qhov zoo dua qhov sealing kev ua tau zoo;
5. Cov khoom siv thiab qhov loj ntawm flange thiab lub taub qab vuam kawg tuaj yeem xaiv tau raws li kev ua haujlwm tiag tiag lossis cov neeg siv khoom kom tau raws li ntau yam kev xav tau ntawm engineering.
