1. Lub ntsiab txhais thiab cov qauv
Qhov muag muag flanged concentric npauj npaim valve (tseem hu ua "center-line butterfly valve") yog lub quarter-tig rotary valve tsim los rau / tawm lossis throttling ntws tswj hauv cov kav dej. Nws cov yam ntxwv tseem ceeb muaj xws li:
Concentric Design: Lub valve qia, disc, thiab lub rooj zaum yog nyob rau hauv tib lub hauv nruab nrab axis, tsim ib qho yooj yim thiab compact qauv.
Mos Sealing Mechanism: Ib qho yooj yim elastomeric foob (piv txwv li, roj hmab, EPDM, NBR) yog muab tso rau hauv lub valve lub cev lossis lub rooj zaum, muab lub foob nruj kom tiv thaiv kom tsis txhob yaig.
Flanged Ends: Lub valve yog nruab nrog flanged kev sib txuas, tso cai yooj yim installation ntawm cov kav dej raws li cov qauv zoo li ANSI, DIN, lossis JIS.
2.Cov ntsiab lus tseem ceeb
3. Txoj Cai Ua Haujlwm
Qhib Txoj Haujlwm: Lub disc tig 90° kom ua raws li cov kev taw qhia ntws, txo qis kev poob siab thiab tso cai rau tag nrho ntws.
Kaw Txoj Haujlwm: Lub disc tig rov qab los nias tiv thaiv lub foob mos, tsim kom muaj kev kaw nruj. Lub concentric tsim cia siab rau lub elastic deformation ntawm lub foob kom ua tiav sealing, ua rau nws zoo heev rau cov ntawv thov uas tsis tshua muaj siab.
4. Cov yam ntxwv tseem ceeb thiab qhov zoo
Tight Sealing: Cov ntsaws ruaj ruaj muab cov dej xau zoo heev, feem ntau ua raws li cov qauv ua npuas (xws li ANSI B16.104 Chav Kawm VI, ISO 15848-1).
Tsawg Torque Kev Ua Haujlwm: Lub concentric tsim thiab saj zawg zog foob txo kev sib txhuam, cia yooj yim phau ntawv khiav lag luam lossis siv nrog lub teeb yuag actuators.
Compact thiab Lightweight: Piv rau lub rooj vag los yog lub ntiaj teb li qub, concentric npauj npaim li qub yog me dua thiab yooj yim rau nruab rau hauv qhov chaw tsawg.
Nqi-zoo: Cov qauv yooj yim thiab siv cov khoom siv tsawg ua rau lawv pheej yig rau cov kev xav tau yooj yim tswj.
Versatile Media Compatibility: Haum rau dej, huab cua, roj, cov kua dej uas tsis muaj corrosive, thiab granular media (nrog rau cov coatings-resistant coatings).
5. Kev qhia tshwj xeeb
Kev ntsuas siab: Feem ntau qis rau nruab nrab siab (piv txwv li, PN6-PN16 / Chav Kawm 125-Chav Kawm 150).
Qhov kub thiab txias:
Txheem elastomers (piv txwv li, NR, EPDM): -10°C rau 90°C (14°F rau 194°F).
High-temperature seals (xws li Viton®, PTFE): -20°C rau 150°C (-4°F rau 302°F).
Standards Ua raws li:
Tsim: EN593, API 609, MSS SP-67.
Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Kev Ntsuas: API 598, (kev kuaj pom).
6. Cov ntawv thov
Mos sealing flanged concentric npauj npaim li qub D341X-16Qyog dav siv nyob rau hauv:
Kev Siv Dej thiab Dej Dej: Cov kav dej hauv nroog, cov chaw kho dej, thiab cov kav dej.
HVAC Systems: Tswj huab cua, dej, lossis chav dej hauv cua sov, qhov cua, thiab cua txias.
Kev lag luam khoom noj khoom haus thiab dej haus: kev siv tshuaj ntxuav tes nrog FDA-raws li cov ntsaws ruaj ruaj (piv txwv li, EPDM nrog cov zaub mov-qib txheej).
Cov txheej txheem kev lag luam dav dav: Cov dej tsis muaj corrosive tuav hauv tshuaj, ntawv, thiab tshuaj nroj tsuag (rau cov xov xwm me me xwb).
Marine thiab Shipbuilding: On / off tswj nyob rau hauv seawater los yog ballast systems (nrog corrosion-resistant cov ntaub ntawv).
7. Kev txwv thiab kev txiav txim siab
Kev ntsuas kub thiab ntsuas kub: Tsis haum rau kev kub siab (piv txwv li,> PN16) lossis cov ntawv thov kub heev (piv txwv li, chav siab tshaj 150°C).
Corrosion Risks: Hlau Cheebtsam (xws li, cam khwb cia hlau lub cev) tej zaum yuav corrode nyob rau hauv ib puag ncig txhoj puab heev; upgrade rau stainless hlau los yog coated cov ntaub ntawv rau hnyav tej yam kev mob.
Abrasive Media: Cov ntsaws ruaj ruaj tuaj yeem hnav tau sai nrog cov kua dej ua kua; xav txog qhov nyuaj-sau npauj npaim li qub lossis cov txheej tiv thaiv ntxiv.
Kev xaiv Actuator: Rau qhov loj-inch li qub lossis ua haujlwm nquag, siv pneumatic / hydraulic actuators kom tsis txhob muaj kev qaug zog ntawm phau ntawv.
8. Kev txhim kho thiab tu
Kev teeb tsa:
Xyuas kom cov flanges tau ua raws thiab cov bolts tau nruj nruj kom tiv thaiv kom tsis txhob tawg.
Tsis txhob txhim kho lub valve nyob rau hauv kev ntxhov siab ntau dhau ntawm cov kav dej.
Kev tu:
Tsis tu ncua tshuaj xyuas lub foob rau hnav los yog tawg, tshwj xeeb tshaj yog nyob rau hauv high-cycle applications.
Lubricate lub qia thiab actuator tsis tu ncua kom ntseeg tau tias kev ua haujlwm zoo.
Hloov lub foob yog tias muaj dej xau; qee qhov kev tsim tso cai rau kev hloov pauv tsis tau tshem lub valve ntawm lub raj xa dej.
9. Tus neeg muab khoom thiab cov lus qhia xaiv cov khoom
Cov ntaub ntawv pov thawj: Xyuas kom cov ntsaws ruaj ruaj raws li cov qauv kev lag luam (xws li FDA rau zaub mov, ATEX rau qhov chaw tawg).
Customization Options: Qee tus neeg muag khoom muaj cov qauv tsim los tiv thaiv zoo li qub, muaj kev nyab xeeb hluav taws, lossis cov txheej txheem tshwj xeeb (xws li, epoxy, PTFE) rau cov ntawv thov niche.
