Nta thiab kev siv:
Lub pob valve eccentric yog cov khoom siv zoo tshaj plaws rau cov thee uas raug txau, cov roj coke hauv qhov cub, cov roj plua plav thiab cov kua dej granular. Nws yog siv dav hauv kev lag luam metallurgy. Muaj cov yam ntxwv hauv qab no.
1. Lub qauv ncaj, ib lub foob, thiab eccentric yog siv tshwj xeeb rau kev ntws ob theem ntawm cov tshuaj tsuag thee uas raug tsoo los ntawm kev txhaj tshuaj. Nws yuav tsis muaj qhov ntws tsis muaj kev thaiv thiab cov xwm txheej daig.
2. Muaj kev them nyiaj rau lub foob kom paub tseeb tias siv tau ntev.
3. Nws yooj yim hloov lub rooj zaum kom tsis txhob muaj kev hloov pauv ntawm tag nrho lub valve.
