GLV504-NP16
Tsim tshwj xeeb los tswj cov tshuaj corrosive thiab kub-kub, lub tshuab raj kaw lub ntiaj teb li qub tau tsim nrog ntau lub ply, hloov tau yooj yim ntawm cov hlau ua kom tsis txhob raug cov tshuaj no. Bellows yog welded rau lub valve lub qia thiab lub kaus mom, nrog rau kev sib khi ntawm cov pob qij txha kom zoo, tshem tawm cov dej xau.Ua tau raws li cov qauv tsim thoob ntiaj teb, peb lub ntiaj teb lub tshuab nqus tsev twj tso kua mis khav theeb zoo sealing kev ua tau zoo thiab lub neej ntev. Cov kws tshaj lij tsim nyog niaj hnub sim peb lub ntiaj teb li qub kom txo qis kev xau, yog li txo cov kev tu ncua.

Kev tsim lub cev
Vim lub kaum sab xis ntawm lub ntiaj teb valve lub cev muaj qhov siab ntawm lub taub hau poob. Lub taub hau poob yog qhov ntsuas ntawm kev txo qis hauv tag nrho lub taub hau ntawm cov kua thaum nws txav mus los ntawm qhov system. Tag nrho lub taub hau poob tuaj yeem suav tau los ntawm kev suav qhov nce lub taub hau, lub taub hau nrawm thiab lub taub hau siab. Thaum lub taub hau poob tsis tuaj yeem zam tau hauv cov kua dej, nws tau nce los ntawm kev cuam tshuam thiab kev tsis sib xws hauv txoj kev ntws xws li S duab ntawm lub ntiaj teb valve tsim. Lub cev thiab cov kav dej ntws yog sib npaug thiab du los muab cov txheej txheem ntws tsis muaj kev sib tw lossis suab nrov. Txhawm rau kom tsis txhob tsim kev poob siab ntxiv ntawm qhov nrawm, cov kav dej yuav tsum yog thaj chaw tas li. Globe li qub muaj nyob rau hauv peb lub cev tseem ceeb (txawm hais tias kev cai tsim muaj xws li): lub kaum sab xis tsim, Y-shaped, thiab Z-shaped.
