Yam Koj Yuav Tsum Paub Txog AWWA Butterfly Valves

Thaum nws los txog rau cov chaw tsim kho dej, kev kho dej khib nyiab, thiab cov kav dej hauv nroog, ob peb hom valve uas ntseeg tau thiab siv dav liAWWA npauj npaim valvePaub txog lawv qhov kev siv nyiaj tsim nyog, yooj yim ua haujlwm, thiab lub neej ua haujlwm ntev, cov li qub no ua lub luag haujlwm tseem ceeb hauv kev tswj cov dej ntws hauv cov kab ke dej loj. Tab sis dab tsi ua rau lawv sawv tawm, thiab koj xaiv qhov yog rau koj daim ntawv thov li cas?

Hauv tsab xov xwm no, peb yuav npog txhua yam koj xav paub txogAWWA npauj npaim li qub—los ntawm cov qauv thiab kev tsim kho mus rau cov ntawv thov thiab cov lus qhia tseem ceeb xaiv.

1. Dab tsi yog AWWA Butterfly Valve

An AWWA npauj npaim valveyog ib hom lub valve uas tig ib feem plaub uas tsim los tswj lossis cais cov dej ntws, tshwj xeeb tshaj yog hauv cov dej thiab cov dej khib nyiab. Lub npe luv "AWWA" sawv cev rauLub Koom Haum Ua Haujlwm Dej Amelikas, uas teeb tsa cov qauv rau kev tsim, kev tsim khoom, thiab kev ua haujlwm ntawm cov li qub siv hauv cov dej hauv nroog thiab cov dej hauv kev lag luam.

Cov lus qhia tshwj xeeb tshaj plaws rau cov valve no yogAWWA C504, uas piav qhia txog cov kev cai rau cov roj hmab-zaum npauj npaim li qub los ntawm 3 nti (75mm) txog 72 nti (1800mm) hauv txoj kab uas hla.

2. Cov yam ntxwv tseem ceeb ntawm AWWA Npauj Npaim Li Qub

1. Kev Ua Haujlwm Ib Feem Plaub
   Lub disc tig 90 degrees kom qhib lossis kaw tag nrho txoj kev ntws, ua rau kev ua haujlwm sai thiab txo qhov poob siab.

2. Zaum tau yooj yim
   Cov li qub no siv cov roj hmab lossis cov rooj zaum elastomeric kom ntseeg tau tias lub foob kaw ruaj khov thiab tiv thaiv kev xau, txawm tias tom qab siv ntev lawm.

3. Kev Tiv Thaiv Kev Xeb
   Cov txheej sab hauv thiab sab nraud (feem ntau yog epoxy) tiv thaiv lub cev valve thiab disc tiv thaiv kev xeb hauv cov dej hnyav.

4. Tsim Qauv Me Me
   Piv rau cov qhov rooj vag, AWWA npauj npaim li qub sib dua thiab siv qhov chaw tsawg dua, uas zoo tagnrho rau kev teeb tsa nruj.

5. Kev Pabcuam Ntev
   Yog tias koj saib xyuas kom zoo, cov li qub no tuaj yeem siv tau ntau xyoo, tshwj xeeb tshaj yog hauv cov dej huv.

3. AWWA C504 VS AWWA C516

ThaumAWWA C504npog cov roj hmab uas muaj roj hmab npog, cov tshiab duaAWWA C516chaw nyobcov npauj npaim ua haujlwm siab (HPBVs), uas tsim nyog rau kev siab dua thiab kev thov ntau dua.

4. Yuav Ua Li Cas Xaiv AWWA Butterfly Valve Kom Yog

1. Qhov Loj ntawm Cov Yeeb Nkab thiab Qhov Ntsuas Siab
   Sib phim qhov loj thiab chav kawm ntawm lub valve nrog rau qhov yuav tsum tau ua ntawm lub system. Cov AWWA valves muaj ntau chav kawm siab (piv txwv li, 150A, 150B).

2. Kev Pabcuam Xov Xwm
   Xyuas kom meej tias cov dej sib xyaw nrog cov khoom siv, cov khoom siv, lossis lwm yam khoom siv.

3. Cov xwm txheej ua haujlwm
   Tshuaj xyuas qhov kub thiab txias, qhov siab, thiab seb puas xav tau kev kaw lossis kev cais tawm.

4. Xaus Kev Sib Txuas
   AWWA npauj npaim li qub muaj nrog flanged, grooved, lossis mechanical joint kawg.

5. Txoj Kev Ua Haujlwm
   Xaiv ntawm kev siv iav tes, hluav taws xob actuators, pneumatic lossis hydraulic systems raws li qhov xav tau ntawm lub kaw lus automation.

6. Cov Ntawv Pov Thawj
   Xyuas kom tseeb tias lub valve ua raws li cov qauv AWWA, thiab yog tias siv rau hauv cov dej haus, nws yuav tsum tau ntawv pov thawj NSF 61.
