Chav tshuab, cua txias dej ncig, thiab ua cov kab ua haujlwm.
2. Npauj Npaim Li Qub
Npauj npaim li qub, tshwj xeeb yog cov uas muaj eccentric lossis triple- Offset}}}}} txoj hauj lwm txoj kab uas hla. Thaum lub sij hawm Paintic Npauj npaim li qub yog haum rau ntawm / tawm kev pabcuam, lawv offset counterparts muaj kev ua tau zoo thiab kev ua yeeb yam.
Cov Nta Tseem Ceeb:
- Kev hnyav thiab chaw - txuag
- Kev ua haujlwm sai
- Kev Tswj Xyuas Nruab Nrab
Cov Kev Siv Cov Ntaub Ntawv Feem Ntau:
HVAC lub tshuab, tso dej rau dej, thiab qis -} Viscosity kua tuav tuav.
3. Pob li qub (v - chaw nres nkoj thiab segectsal hom)
Tsoos ib txwm muaj li qub yog tsis zoo rau lub ntsej muag vim lawv qhov kev qhib sai thiab kaw profile. Txawm li cas los xij, tshwj xeeb tsim v- chaw nres nkoj lossis segectingal pob cov duab uas tso cai rau kev tswj hwm kev ntws ntau. Cov li qub no ua ke cov txiaj ntsig ntawm lub quarter - khiav haujlwm nrog cov khoom muaj zog zoo dua.
Cov Nta Tseem Ceeb:
- Tsawg Lub Zog Ua Haujlwm
- Txhim Kho Flow Control (piv rau cov qauv pob li qub)
- Ruaj khov nyob rau hauv slurry lossis viscous media applications
Cov Kev Siv Cov Ntaub Ntawv Feem Ntau:
Pulp thiab cov ntawv lag luam, tshuaj noj tshuaj chosing, thiab cov kev pab slurry.
4. Koob Raug Li Qub
Koob roj li qub muab kev tswj tau zoo tshaj qhov chaw ntws, tshwj xeeb yog hauv cov ntawv thov tsawg}. Lub Tapered Koob {{2} Zoo li cov plunger tso cai rau kev kawm zuj zus thiab meej haum ntawm kev ntws, ua rau lawv zoo tagnrho rau kev ntsuas thiab kuaj cov tshuab.
Cov Nta Tseem Ceeb:
- Siab Precision Tswj
- Qhov zoo tshaj plaws rau cov nqi ntws qis thiab me me - txoj hauj sam uas hla
- Los ntawm txhais tes ua haujlwm nkaus xwb
Cov Kev Siv Cov Ntaub Ntawv Feem Ntau:
Siab nqus kev suav, ntws caliburation, thiab cov kab piv txwv.
5. Tswj li qub (Actuated hom)
Tswj cov li qub -} nruab nrog cov neeg ua yeeb yam thiab cov phiaj xwm {{luas} tsim rau kev tso dej ntws. Cov ntoo roj no tuaj yeem yog ntiaj teb, pob, lossis npauj npaim nyob rau hauv kev tsim, tab sis sib xyaw nrog cov tswv yim ntse los tswj cov cim.
Cov Nta Tseem Ceeb:
- Caw kaw lus thiab muaj kev teb heev
- Kev sib xyaw ua ke nrog cov txheej txheem tswj cov tshuab (piv txwv li PLC, DCS)
- Qhov zoo tshaj plaws rau kev tswj hwm ntws hluav taws xob
Cov Kev Siv Cov Ntaub Ntawv Feem Ntau:
Cov txheej txheem kev lag luam, cov nroj tsuag hluav taws xob, roj thiab roj av, thiab cov dej kho kom dej.
Thaum muaj ntau hom Valve tuaj yeem siv rau hauv / tawm cov xwm txheej, tsuas yog tsim tshwj xeeb yog qhov ua tau zoo rau kev tswj hwm txaus. Globe valves, butterfly valves (especially triple-offset), V-port ball valves, needle valves, and automated control valves all offer unique advantages depending on the application. Xaiv qhov tsim nyog tswj hwm lub valve yuav tsum xav txog yam xws li ntws cov yam ntxwv, siab poob, system dynamics, thiab cov kev xav tau kev pab kho.
