Hauv kev yuav khoom ntawm npauj npaim li qub, peb feem ntau hnov cov lus hais ntawm pinned npauj npaim valve thiab pinless npauj npaim valve.Vim yog cov laj thawj thev naus laus zis, pinless npauj npaim valve feem ntau yog kim dua li pinless npauj npaim valve, uas ua rau ntau tus neeg siv khoom xav tias seb tus pinless npauj npaim valve yog kim dua li pinless butterfly valve.Puas yog tus pin npauj npaim valve zoo dua?Yuav ua li cas hais txog kev sib piv ntawm pinned npauj npaim valve thiab pinless npauj npaim valve?
Los ntawm qhov pom ntawm qhov pom, qhov sib txawv tseem ceeb tshaj plaws ntawm tus pinned npauj npaim valve thiab pinless npauj npaim valve yog: seb puas muaj tus pin tapered tso rau ntawm lub phaj valve.Kev sib txuas ntawm lub phaj valve thiab lub qia valve nrog tus pin yog tus pin npauj npaim valve, thiab rov qab yog tus pinless npauj npaim valve.Rau pinned npauj npaim li qub thiab pinless npauj npaim li qub, lawv muaj lawv tus kheej qhov zoo thiab qhov tsis zoo.
Qhov xwm txheej tshwj xeeb yog raws li nram no:
Cov tsos mob sib piv - lub pinned npauj npaim valve muaj qhov pom tseeb tus pin taub hau protrusions ntawm cov tsos, uas tsis yog du thiab zoo nkauj li lub pinless npauj npaim valve, tab sis nws tsis muaj kev cuam tshuam loj rau tag nrho cov tsos.
Kev sib piv cov txheej txheem - cov qauv thiab cov txheej txheem ua tiav ntawm tus pin npauj npaim valve yuav yooj yim, tab sis yog tias yuav tsum muaj kev saib xyuas tom qab siv mus ntev, nws yuav muaj teeb meem ntau dua rau disassemble lub ncej thiab valve phaj.Nws tsis yooj yim rau tshem tawm lub qia valve vim hais tias cov pins feem ntau ntaus yog piled thiab nias nyuaj nrog ib tug xovxwm.Lub pinless npauj npaim valve yuav nyuaj rau cov qauv thiab thev naus laus zis vim tias muaj ntau txoj hauv kev sib kis, tab sis tom qab kev kho thiab disassembly yog yooj yim dua thiab yooj yim rau kev txij nkawm.
Kev sib piv kev ruaj ntseg - Npauj npaim li qub nrog pins yog qhov ruaj khov dua li cov tsis muaj pins vim tias lawv tau kho nrog pins.Cov qauv pinless cuam tshuam rau qhov tseeb ntawm qhov kev txiav txim vim qhov hnav ntawm mating nto ntawm lub ncej thiab lub rooj vag tom qab ua haujlwm ntev.
Sealing Comparison - Thaum kawg, cia peb saib qhov sib piv ntawm sealing effect.Muaj lus hais tias nyob rau hauv qhov tseeb daim ntawv thov ntawm npauj npaim valve nrog tus pin, qhov nruab nrab yuav nkag tau los ntawm qhov chaw uas tus pin yog pinned rau ntawm lub valve phaj thiab lub valve qia.Qhov kev phom sij zais cia los ntawm qhov no yog tias tus pin yog corroded thiab tawg tom qab lub sijhawm ntev, ua rau lub valve tsis ua haujlwm, lossis teeb meem ntawm ejector leakage lossis sab hauv to hauv cov raj xa dej.
Piv txwv li, piv cov pinned npauj npaim valve thiab pinless npauj npaim valve, lub hom phiaj hais lus, txhua tus qauv tsim muaj nws tus yam ntxwv thiab qhov zoo, thiab nws tsis yooj yim sua kom hais qhov twg zoo dua.Tsuav peb xaiv cov khoom tsim nyog tshaj plaws rau peb cov nqi siv nyiaj thiab peb cov kev ua haujlwm, nws yog ib qho khoom zoo rau peb.
