1. Cov Lus Txhais thiab Cov Qauv Tseem Ceeb
Lub valve uas muaj flanged concentric uas kaw tau zoo (tseem hu ua "center-line butterfly valve") yog lub valve uas tig ib feem plaub ntawm lub voj voog uas tsim los rau kev qhib/kaw lossis kev tswj cov dej ntws hauv cov kav dej. Nws cov yam ntxwv tseem ceeb suav nrog:
Tsim Concentric: Lub valve stem, disc, thiab lub rooj zaum tau sib dhos rau ntawm tib lub hauv paus axis, tsim kom muaj cov qauv yooj yim thiab compact.
Lub Tshuab Kaw Mos: Lub foob elastomeric uas yoog tau (piv txwv li, roj hmab, EPDM, NBR) tau koom ua ke rau hauv lub cev valve lossis lub rooj zaum, muab lub foob nruj kom tiv thaiv kev xau.
Cov Qhov Kawg Flanged: Lub valve muaj cov kev sib txuas flanged, ua rau yooj yim rau kev teeb tsa ntawm cov kav dej ua raws li cov qauv xws li ANSI, DIN, lossis JIS.
2.Cov Cheebtsam Tseem Ceeb
3. Txoj Cai Ua Haujlwm
Qhov Chaw Qhib: Lub disc tig 90° kom sib haum nrog qhov kev taw qhia ntawm cov dej ntws, txo qhov kev poob siab thiab tso cai rau kev ntws tag nrho.
Qhov Chaw Kaw: Lub disc tig rov qab los nias rau ntawm lub foob mos, tsim kom kaw nruj. Tus qauv concentric vam khom rau qhov elastic deformation ntawm lub foob kom ua tiav kev sib khi, ua rau nws zoo heev rau cov ntawv thov qis siab.
4. Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig
Kev Kaw Nruj: Cov foob mos mos muab kev tiv thaiv zoo heev rau kev xau, feem ntau ua tau raws li cov qauv tsis muaj npuas (piv txwv li, ANSI B16.104 Class VI, ISO 15848-1).
Kev Ua Haujlwm Torque Qis: Tus qauv tsim concentric thiab lub foob hloov pauv tau txo qhov kev sib txhuam, ua rau kev ua haujlwm tes yooj yim lossis siv nrog cov actuators sib dua.
Kev Me Me thiab Lub Teeb Meem: Piv rau lub qhov rooj lossis lub ntiaj teb li qub, cov li qub npauj npaim concentric me dua thiab yooj yim dua rau kev teeb tsa hauv qhov chaw tsawg.
Tus nqi tsim nyog: Cov qauv yooj yim thiab kev siv khoom tsawg ua rau lawv pheej yig rau cov kev xav tau tswj kev ntws yooj yim.
Kev Sib Txuas Lus Ntau Yam: Haum rau dej, cua, roj, kua tsis xeb, thiab cov khoom siv granular (nrog cov txheej tiv taus kev txhuam).
5. Cov Lus Qhia Txog Kev Siv
Kev Ntsuas Siab: Feem ntau qis mus rau nruab nrab siab (piv txwv li, PN6–PN16 / Chav Kawm 125–Chav Kawm 150).

Kev Ua Raws Cai ntawm Cov Qauv:
Tsim: EN593, API 609, MSS SP-67.
Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Kev Ntsuas: API 598, (kev ntsuam xyuas xau).
