Peb hom npauj npaim li qub yog dab tsi?
Npauj npaim li qub feem ntau siv hauv ntau qhov kev lag luam los tswj cov dej ntws. Lawv yog lub teeb yuag, ruaj, thiab yooj yim hauv kev tsim, ua rau lawv haum rau ntau yam kev siv. Nrog lawv cov versatility, npauj npaim li qub tau dhau los ua ib feem tseem ceeb ntawm ntau lub tshuab. Hauv tsab xov xwm no, peb yuav delve rau hauv peb hom kab npauj npaim li qub thiab tshawb txog lawv cov yam ntxwv tshwj xeeb.
1. Wafer style npauj npaim li qub
Wafer style npauj npaim li qub yog hom siv feem ntau vim lawv cov qauv tsim thiab yooj yim ntawm kev teeb tsa. Cov li qub no tsis muaj lub cev flanged thiab muab tso rau ntawm ob lub yeeb nkab flanges. Lawv feem ntau tuav nyob rau hauv qhov chaw los ntawm bolts los yog txiv ntseej, compressing lub valve ntawm lub flanges los tsim ib tug nruj seal.
Ib qho txiaj ntsig ntawm wafer style npauj npaim li qub yog lawv qhov hnyav thiab me me hneev taw. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov chaw txwv. Lawv kuj raug nqi zoo piv rau lwm hom li qub. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias wafer style npauj npaim li qub tsis haum rau cov ntawv thov siab vim lawv tso siab rau lub siab ntawm flanges los tuav lub foob.
2. Lug style npauj npaim li qub
Lug style npauj npaim li qub, tseem hu ua semi-lugged npauj npaim li qub, zoo ib yam li wafer style li qub tab sis nrog ntxiv lugs ntawm lub valve lub cev. Cov lugs no pab kom lub valve yuav tsum tau ntsia siv bolts yam tsis xav tau cov txiv ntseej, simplifying lub installation txheej txheem. Lub lugs tseem tso cai rau lub valve tshem tawm txawm tias thaum lub raj xa dej nyob rau hauv lub siab, ua rau kev saib xyuas yooj yim dua.
Lug style npauj npaim li qub feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau saib xyuas ntau zaus lossis qhov twg cov kav dej yuav tsum tau muab tshem tawm ib ntus. Lawv muab ob-directional sealing, txhais tau tias lawv tuaj yeem thaiv kev ntws mus rau ob qho tib si. Lawv cov qauv tsim tso cai rau lawv los tswj cov kev ntxhov siab dua piv rau wafer style li qub, ua rau lawv haum rau ntau yam kev siv.
3. Ob chav offset npauj npaim li qub
Ob chav offset npauj npaim li qub muaj ntau txoj hauv kev tsim dua li wafer thiab lug style li qub. Lawv muaj ib tug disc uas yog offset los ntawm ob qho tib si centerline ntawm cov yeeb nkab thiab lub centerline ntawm lub valve bore. Qhov kev tsim no txo qhov kev sib cuag ntawm lub disc thiab lub rooj zaum, ua rau txo kev sib txhuam thiab hnav.
Cov li qub no muaj ntau yam zoo, nrog rau kev sib khi kom nruj, txhim khu kev ruaj ntseg, thiab tiv taus qhov kub thiab txias. Lawv feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau kaw nruj nreem, xws li hauv kev lag luam roj thiab roj. Ob chav offset npauj npaim li qub kuj yog qhov zoo tagnrho rau cov ntawv thov kev sib txhuam qis, vim tias qhov offset disc txo cov torque yuav tsum tau ua haujlwm ntawm lub valve.
Xaus
Hauv kev xaus, npauj npaim li qub yog ntau yam thiab siv dav hauv ntau yam lag luam. Peb hom npauj npaim li qub yog wafer style, lug style, thiab ob chav offset li qub. Txhua hom muaj nws tus yam ntxwv tshwj xeeb thiab qhov zoo, ua rau lawv haum rau kev siv sib txawv. Wafer style li qub yog compact thiab yooj yim rau nruab, thaum lug style li qub muab kev saib xyuas yooj yim. Ob chav offset li qub, ntawm qhov tod tes, muab nruj sealing thiab durability. Nkag siab qhov sib txawv thiab muaj peev xwm ntawm cov npauj npaim valve hom no yog qhov tseem ceeb rau kev xaiv lub valve uas tsim nyog tshaj plaws rau ib daim ntawv thov tshwj xeeb.
