Lub viav vias kos li qub feem ntau ntsia kab rov tav, tab sis ntev li ntev tau koj zam lub valve kom ncav cuag qhov chaw tuag, koj tuaj yeem ntsia tau ntsug. Nyob rau hauv cov ntaub ntawv ntawm ntsug installation, lub valve kaw torque yog generated los ntawm nws lub ntiajteb txawj nqus, vim lub valve nyob rau hauv lub siab qhib txoj hauj lwm thaum lub kaw torque yog heev me me, yog li ntawd lub valve yuav ncua kaw. Txhawm rau kov yeej qhov tsis txaus ntawm lub valve qeeb teb rau qhov nruab nrab tsis ruaj khov, lub valve tuaj yeem teeb tsa rau lub zog ntawm lub cev hnyav lossis lub caij nplooj ntoos hlav los pab kev thauj khoom.

Lub Vev Xaib Valves
Lub disc ntawm lub viav vias kos valve yog disc-puab thiab rotates nyob ib ncig ntawm lub rotating ncej ntawm lub valve rooj channel. Vim hais tias cov channel nyob rau hauv lub valve yog streamlined, cov ndlwg tsis kam yog me dua li ntawm lub lift check valve. Nws yog qhov tsim nyog rau lub sijhawm loj-caliber nrog tus nqi qis qis thiab tsis tshua muaj kev hloov pauv, tab sis tsis haum rau cov dej ntws tawm. Nws sealing kev ua tau zoo tsis zoo li lub tshuab nqa check valve. Lub viav vias kos li qub tau muab faib ua ib hom nrov nrov, ob hom nrov nrov thiab ntau hom nrov nrov. Peb hom no feem ntau muab faib raws li lub valve txoj kab uas hla. Lub hom phiaj yog txhawm rau tiv thaiv qhov nruab nrab los ntawm kev txwv tsis pub ntws los yog rov qab thiab ua kom tsis muaj zog ntawm qhov cuam tshuam hydraulic.
