Ib lub valve uas qhib lossis kaw cia los ntawm kev quab yuam ntawm nruab nrab ntws los tiv thaiv cov nruab nrab los ntawm qhov ntws rov qab yog hu ua ib tug check valve. Xyuas li qub yog siv rau lub tshuab tsis siv neeg ib txwm thiab muaj feem ntau siv nyob rau hauv pipelines uas lub nruab nrab ntws hauv ib qho kev taw qhia. Lawv tsuas yog cia cov nruab nrab ntws hauv ib qho kev taw qhia los tiv thaiv kev huam yuaj.
Kev faib tawm cov qauv txheej txheem
Raws li cov qauv, nws tuaj yeem faib ua peb hom: nqa kos kos kos duab valve, viav vias kos valve valve thiab npauj npaim kos valve:
1. Nqa tshuaj xyuas li qub yog muab faib ua hom ntsug thiab kab rov tav.
2. Viav vias sceck li cas tau muab faib ua ib qho-nrov plig plawg, nrov plig plawg thiab nrov plig plawg thiab ntau-flap hom.
3. Npauj npaim xyuas cov khoom yog qhov ncaj-los.
Cov kev kuaj xyuas saum toj no yuav muab faib ua plaub hom ntawm cov nqe lus sau: xov txuas, floring kev txuas, vuam txuas thiab clamp txuas.
