Yuav Ua Li Cas Xaiv Npauj Npaim Valve
Khoom siv:Coj mus rau hauv tus account qhov kev khiav hauj lwm ib puag ncig, tsim lub neej, thiab qhov xwm ntawm cov xov xwm raug tuav. Xav txog yam xws li kub, siab, corrosiveness, thiab tus nqi thiab muaj cov ntaub ntawv sib tw. Cov kev xaiv muaj xws li: carbon steel, stainless hlau, PVC (polyvinyl chloride), thiab CPVC (chlorinated polyvinyl chloride).
Valve Loj:Thaum txiav txim siab valve loj, xav txog qhov tshwj xeeb lub ntiajteb txawj nqus thiab viscosity ntawm cov kua; inlet thiab qhov hluav taws xob pressures; muaj peev xwm siab tshaj plaws; thiab siab kawg siab poob.
Hom Lub Rooj:Cov rooj zaum muaj zog, tsim los ntawm cov ntaub ntawv elastomeric xws li Buna-N®, EPDM (ethylene propylene diene monomer), thiab Viton®, muab kev sib khi zoo heev. Ntawm qhov tod tes, cov rooj zaum hlau, feem ntau yog tsim los ntawm cov hlau tsis muaj steel lossis lwm cov hlau alloys, yog qhov zoo dua rau kev siv siab thiab kub kub.
Hom Disk:Concentric disks ua haujlwm zoo nyob rau hauv qhov chaw tsis tshua muaj siab, whereas eccentric disks (ob npaug los yog triple offset) yog qhov tsim nyog rau qhov chaw muaj kev kub ntxhov, muab kev tswj kom zoo thiab kev sib khi ua haujlwm.
Hom Actuator:Xaiv los ntawm peb hom actuator tseem ceeb: hluav taws xob, phau ntawv qhia, thiab pneumatic. Manual actuators yog ua los ntawm tes thiab muab kev yooj yim. Hluav taws xob thiab pneumatic actuators, ntawm qhov tod tes, muab automation, uas tuaj yeem ua tau zoo tshwj xeeb rau cov tshuab loj lossis cov chaw taws teeb uas yuav tsum tau hloov kho, qhov tseeb txaus, txhim khu kev tswj hauv kev ua haujlwm valve.
Ceev ntawm Actuators:Fast-acting actuators yog qhov zoo tagnrho rau kev sib cais ceev lossis qhib thaum lub sijhawm ua haujlwm qeeb yog tsim nyog rau kev tswj hwm, maj mam hloov kho.
Cov kua dej:Qhov xwm txheej ntawm cov kua txav los yog roj ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov tsim nyog valve hom thiab cov khoom siv disk. Rau cov tshuab siv roj, cov li qub yuav tsum tau muab kaw kom nruj kom ua tau raws li qhov yuav tsum tau muaj cov pa xau. Rau cov ntawv thov slurry, tshwj xeeb tshaj yog cov uas muaj cov khoom abrasive, cov kev txiav txim siab suav nrog kev tiv thaiv kev hnav ntxov ntxov ntawm cov rooj zaum roj hmab, hais txog qhov cuam tshuam ntawm qhov chaw tsim los ntawm lub disk, thiab zam cov teeb meem xws li disk jamming lossis cov khoom ntim ntawm lub disk thiab lub rooj zaum. Cov no ntau dua li cuam tshuam cov dej ntws ua haujlwm, ua rau lub valve tsis tuaj yeem qhib, kaw, lossis tswj tus nqi xav tau.
Dab tsi yog cov khoom siv npauj npaim li qub ua los ntawm?
Npauj npaim li qub yog tsim los ntawm cov khoom sib txawv kom haum rau ntau yam kev ua haujlwm. Hauv qeb hlau, stainless hlau yog dav siv rau nws lub zog thiab corrosion kuj nyob rau hauv tuav acidic los yog corrosive kua nyob rau hauv txawv kub thiab siab ntau yam. Cov pa roj carbon steel muaj kev xaiv tus nqi zoo rau kev siv siab thiab qis. Lwm cov ntaub ntawv, xws li tooj dag, npib tsib xee alloys, titanium alloys, thiab npib tsib xee txhuas bronze muaj txiaj ntsig zoo rau lawv cov kev tiv thaiv ib puag ncig corrosive thiab kub siab.
Plastic npauj npaim li qub yog tsim los ntawm cov ntaub ntawv xws li polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polypropylene (PP), iav fiber ntau zog polypropylene (GFPP), polyvinylidene fluoride (PVDF), thiab acrylonitrile butadiene styrene (ABS). Lawv muab lub teeb yuag, kev tiv thaiv corrosion-resistant rau ntau yam kev siv, raws li kev txwv kub.
Lub rooj zaum npauj npaim valve, uas tiv thaiv cov kua dej tawm, tuaj nyob rau hauv ob pawg tseem ceeb: rooj zaum mos thiab rooj zaum hlau. Cov rooj zaum mos, ua los ntawm cov ntaub ntawv zoo li PTFE (polytetrafluoroethylene), RTFE (reinforced tetrafluoroethylen), EPDM (ethylene propylene diene monomer), Buna-N®, Viton®, thiab Neoprene® muaj ntau yam kub thiab tshuaj lom neeg. Cov rooj zaum hlau, ua los ntawm cov hlau tsis muaj steel, Stellite®, thiab cov rooj zaum nitrided steel tiv taus qhov kub thiab txias hauv qhov chaw nyuaj.
