Yuav xaiv li cas
Lub rooj vag li qub thiab npauj npaim li qub yog hom kev tswj cov kua dej siv hauv cov kav dej. Lawv ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv. Kev xaiv hom valve tsim nyog yuav tsum xav txog ntau yam, suav nrog cov khoom siv dej, kev ua haujlwm siab, qhov kub thiab txias, qhov xav tau txaus, thiab kev ua haujlwm. Cov ntu hauv qab no qhia txog cov hauv paus ntsiab lus rau kev xaiv lub rooj vag li qub thiab npauj npaim li qub.
Cov khoom ntawm cov kua dej yog ib qho tseem ceeb ntawm kev xaiv lub valve. Lub rooj vag li qub yog tsim rau cov ntawv thov uas xav tau siab ntawm cov dej ntws, xws li cov xwm txheej yuav tsum tau kaw kom tiav - tawm ntawm cov dej ntws. Lawv muab kev kaw zoo heev -off thiab sealing kev ua tau zoo, tiv thaiv cov kua dej kom zoo. Npauj npaim li qub, ntawm qhov tod tes, tsim nyog rau cov ntawv thov uas muaj cov nqi ntws siab thiab tsis tshua muaj siab poob, qhov uas yuav tsum tau ua rau cov dej ntws tau qis dua. Qhov zoo ntawm npauj npaim li qub muaj xws li kev tsim kho yooj yim, lub teeb yuag, thiab kev ua haujlwm yooj yim.
Kev khiav hauj lwm siab thiab qhov kub thiab txias yuav tsum tau txiav txim siab. Cov rooj vag li qub feem ntau haum rau siab -siab thiab siab- qhov kub thiab txias, muaj peev xwm tiv taus qhov kub thiab txias hloov pauv. Npauj npaim li qub muaj qhov ua haujlwm qis dua thiab qhov kub thiab txias thiab tsim nyog rau kev tswj xyuas cov dej hauv kev ua haujlwm dav dav.
Cov kev xav tau ntws yog qhov tseem ceeb thaum xaiv cov li qub. Vim lawv cov yam ntxwv ntawm cov qauv, lub rooj vag li qub feem ntau muaj qhov chaw ntws loj dua thiab tsim nyog rau siab - cov ntawv thov ntws. Hauv qhov sib piv, npauj npaim li qub muaj peev xwm qis dua, yog li qhov loj dua yuav xav tau rau siab - cov ntawv thov ntws.
Cov txheej txheem ntawm kev ua haujlwm yuav tsum tau txiav txim siab. Feem ntau, rooj vag li qub yog ua manually lossis hluav taws xob; thaum kev ua haujlwm yog qhov yooj yim, nws yuav tsum tau siv zog ntau lub cev. Npauj npaim li qub, ntawm qhov tod tes, tuaj yeem ua haujlwm manually, hluav taws xob, lossis pneumatically, muab cov haujlwm sib dua thiab hloov tau yooj yim dua.
Daim ntawv thov
Lub rooj vag valve yog ib hom valve uas ua haujlwm nrog cov lus tsa suab, tswj cov dej ntws los ntawm kev nce lossis txo lub rooj vag. Lub rooj vag li qub yog tsim rau cov ntawv thov uas yuav tsum tau kaw cov kua dej kom tiav, xws li hauv cov kav dej uas xav tau kev saib xyuas lossis kho. Txawm li cas los xij, lub rooj vag li qub muaj qhov qhib thiab kaw nrawm thaum kaw nrawm - tawm lossis qhib cov kua dej yuav tsum tau ua. Lawv tsim nyog rau kev tswj hwm - kub, siab - siab, lossis siab - cov kua dej viscosity, muab kev kaw zoo heev - tawm kev ua haujlwm thiab hnav tsis kam. Tsis tas li ntawd, lub rooj vag li qub muab kev ua tau zoo sealing zoo, tiv thaiv kom tsis txhob xau.
Npauj npaim valve yog ib hom valve uas ua haujlwm ntawm kev sib hloov, tswj cov kua dej los ntawm kev tig lub disc. Npauj npaim li qub yog tsim rau cov ntawv thov uas yuav tsum tau kaw ceev -tawm lossis qhib cov dej ntws, xws li hauv cov tshuab tsim los tswj tus nqi ntws lossis dej kub. Vim tias npauj npaim li qub qhib thiab kaw sai, lawv cov kev siv tuaj yeem txhim kho kev ua haujlwm zoo hauv cov ntawv thov uas yuav tsum tau ua haujlwm ntau zaus. Npauj npaim li qub yog tsim rau kev tswj qis - kub, qis - siab, los yog qis - kua viscosity thiab muaj cov kua dej tsawg. Tsis tas li ntawd, npauj npaim li qub feature ib qho yooj yim tsim thiab compact loj, ua rau lawv yooj yim rau nruab thiab tswj.
