Titanium plug valve ob lub foob qauv los ntawm kev tsim ntawm ob lub foob thiab ntau -theem foob mechanism, zoo heev txhim kho kev ntseeg siab ntawm foob. Cov haujlwm tshwj xeeb thiab kev txhim kho yog raws li hauv qab no:
I. Lub luag haujlwm tseem ceeb ntawm Dual -Cov qauv sib khi
Bidirectional Leak Tiv Thaiv Muaj peev xwm
Titanium pob yog tsim los muab ob npaug rau ntim nrog ob txheej ntawm cov khoom sib khi (xws li cov foob mos + tawv foob cov qauv) ntawm qhov kawg ntawm lub pob lossis ntawm qhov chaw kaw. Piv txwv li, titanium pob muaj ob lub -channel zawj foob nplhaib qauv uas tso cai rau cov foob mos mos bushing kom ruaj khov rau hauv lub valve lub cev, thaum lub foob tawv (xws li hlau rau hlau) ua raws li kev thim rov qab, tsim kom muaj ob txoj kev thaiv. Qhov kev tsim no ua kom xoom xoom thaum qhov nruab nrab ntws mus rau hauv ob qho tib si cov lus qhia, thiab tshwj xeeb tshaj yog tsim nyog rau kev sib khi nruj, xws li aviation kerosene thiab natural gas.
Kho kom haum rau kev ua haujlwm nyuaj
Kub them nyiaj: Ob chav zawj sealing nplhaib tuaj yeem nqus tau me ntsis deformation ntawm bushing los ntawm qhov kub thiab txias hloov thiab zam qhov sib txawv ntawm kub thiab txias shrinkage qhov sealing nto.
Media erosion kuj: Cov ntsaws ruaj ruaj (piv txwv li PTFE, FR) yog cov corrosion kuj heev, thaum cov ntsaws ruaj ruaj (xws li tawv chrome txheej, hlau thaub qab) yog puas thiab hluav taws resistant. Kev sib xyaw ua ke ntawm ob tuaj yeem tiv taus qhov yaig ntawm oxidizing corrosive media, viscous nruab nrab lossis crystallization ua haujlwm.
Kev tu thiab kev nyab xeeb online
Muab ob npaug rau sealing qauv yog saws kom ua tiav ntawm -txoj kab tu yam tsis tau tshem cov yeeb nkab hloov cov ntsaws ruaj ruaj. Piv txwv li, ob chav kaw lifting nres valve nrog lub hauv qab kawg npog tsim uas tso cai rau tshem tawm ncaj qha ntawm lub kaw slider rau hloov, txo downtime. Tsis tas li ntawd, cov khoom tsim ua - nyob rau hauv lub siab nyem tuaj yeem ntes cov foob tsis ua haujlwm thiab tso tawm lub siab, tiv thaiv qhov txawv txav ntawm lub valve kab noj hniav, thiab txhim kho kev nyab xeeb.
II. Technical Paths los txhim kho sealing kev ntseeg tau
Multi-theem sealing tsim
Mos- hard composite sealing: Cov foob mos (xws li roj hmab, PTFE) muab qhov pib sealing quab yuam, thaum lub foob tawv (xws li hlau, ceramic) muab kev ruaj ntseg thib ob. Piv txwv li, lub sealing swb ntawm ob npaug - pob valve compacts lub nplhaib elastic seal thaum kaw thiab cov hlau thaub qab ua hluav taws kub - foob foob, txo tus nqi xau mus rau xoom.
Muab ob npaug rau kev ua haujlwm: nias ob qhov sib cais sib cais zawv zawg daim hlau nyob rau sab sauv thiab hauv qab ntawm lub qhov valve kom ua tiav ob lub ntsaws. Thaum lub qhov tso tawm tau qhib, cov nyhuv sealing tuaj yeem kuaj xyuas kom ntseeg tau tias cov xov xwm tawm hauv lub valve kom tsis txhob muaj kev sib kis yog tias muaj ib qho - txoj kev xau.
Dynamic Foob Optimization
Kev tsim qauv tsis sib cuag: Nyob rau hauv tus txheej txheem ntawm lub valve qhib thiab kaw, lub valve lub cev npog thiab zawv zawg phaj npog tsis txhob kov ncaj qha, txo kev sib txhuam poob thiab ua haujlwm ntev. Piv txwv li, ob lub - ntsaws ntsaws valve yog kaw txoj kev thiab lub stopper rotates 90 degrees thiab ces txav vertically. Lub tshuab ntsuas synchronous qhia txog cov xwm txheej ntawm kev hloov pauv kom ntseeg tau tias qhov chaw sib khi tsis hnav.
Cov kua dej dynamic siab them nyiaj: Ua kom zoo dua qhov chaw nres nkoj geometry (xws li lub khob hliav qab, channel curvature vojvoog, thiab lwm yam) rau 30-45 degree, txo qhov poob siab kom tsawg dua 0.5 bar, thiab them nyiaj rau qhov tsis txaus static preload siv cov kua dej siab gradient los ua cov nyhuv dynamic siab.
Cov ntaub ntawv thiab txheej txheem innovation
High-cov ntaub ntawv sealing kev ua tau zoo: cov khoom siv tes tsho raug xaiv raws li cov yam ntxwv nruab nrab, xws li PTFE (PTFE) -cov roj nplua nyeem ua kom ntev lub neej kev pab cuam thiab fluoride fluororubber compression molding los xyuas kom meej tias lawv tsis poob.
Kev soj ntsuam ntse thiab ceeb toom ntxov
Embed hluav taws xob ua haujlwm polymer (EAP) cov ntsaws ruaj ruaj uas kho qhov deformation nruj rau qhov hloov pauv siab (± 50 bar) nyob rau lub sijhawm tiag tiag ntawm cov hluav taws xob sab nraud.
Los ntawm kev siv tshuab kev kawm algorithm los txheeb xyuas qhov tsis xws li foob qhov kub thiab txias, qhov ua tsis tiav tau kwv yees rau 95% kev ntseeg siab, thiab lub sijhawm teb ntawm lub tswb yog luv luv rau tsawg dua 10 ms.
III. Daim ntawv thov scenarios thiab qhov zoo
Titanium pob valve ob chav sealing qauv yog dav siv nyob rau hauv kev lag luam petrochemical, kev thauj mus los ntawm cov roj av, kev kho dej thiab lwm yam, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej hauv qab no:
Ob -txoj kev ntws cov yeeb nkab: Piv txwv li, steel Hoobkas ncig dej ob- txoj kev tswj cov yeeb nkab yuav tsum tau hloov mus rau qhov rov qab ntws ntawm cov xov xwm, muaj cov cai nruj heev rau kev sib khi.
Kev kub siab sib txawv: Cov kua roj lubrication zaj duab xis (nruab nrab ntawm 0.1 thiab 2 μm hauv tuab) txo qhov hnav, thiab Reynolds sib npaug piav qhia txog cov txheej txheem siab ntawm cov membrane uas ua kom muaj kev ruaj ntseg ntawm qhov sib txawv siab ntawm 100 bar.
Corrosive nruab nrab ib puag ncig: Inert coatings (xws li zirconia ceramic) tsim cov tshuaj barrier nrog qib siab tshaj plaws ntawm corrosion resistance ISO15156-2 tus qauv thiab tsim nyog rau corrosive media xws li hydrofluoric acid.
