Muaj nuj nqi ntawm Blast Door System
Nrog rau kev nthuav dav sai ntawm kev lag luam muaj kev pheej hmoo siab xws li chemical engineering, lub zog cia, thee mining, nuclear fais fab thiab kev tiv thaiv huab cua hauv pej xeem, tej zaum yuav muaj kev phom sij tawg. Raws li qhov tseem ceeb ntawm kev tiv thaiv kev tiv thaiv, lub qhov rooj tawg ua lub luag haujlwm tseem ceeb: tiv thaiv cov hluav taws xob tawg tam sim ntawd, thaiv qhov siab - cov pa roj cua kub thiab siab - tawg tawg, txwv tsis pub tawg ntawm lub zog tawg, thiab tiv thaiv kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.
Kev tawg yog yam ntxwv ntawm instantaneity, siab zog thiab muaj zog destructiveness. Millisecond-theem blast overpressure, siab- tawg tawg nrawm thiab siab- kub kub tuaj yeem ua rau muaj kev puas tsuaj loj rau lub tsev loj thiab kev teeb tsa sab hauv, thiab ua rau muaj kev puas tsuaj rau theem nrab suav nrog hluav taws kub, cov pa roj paug thiab cov deflagrations txuas ntxiv. Cov qhov rooj qub, qhov rais thiab qhov rooj hluav taws tsis muaj peev xwm tiv taus qhov cuam tshuam ib ntus thiab tsis tuaj yeem ua raws li cov qauv kev tiv thaiv rau siab - qhov chaw muaj kev pheej hmoo.
Lub qhov rooj tawg tau pib tsim los rau kev tiv thaiv tub rog thiab kev tiv thaiv huab cua hauv pej xeem, thiab txij li ntawd los tau siv dav hauv kev tawg- thaj chaw muaj kev phom sij xws li cov nroj tsuag petrochemical, lithium roj teeb kev cob qhia, cov chaw tsim tshuaj phom sij, cov chaw cia khoom siv hluav taws xob, cov chaw taws teeb hluav taws xob thiab cov chaw khaws ntaub ntawv. Tsis meej pem txog cov ntsiab lus muaj feem cuam tshuam feem ntau tshwm sim hauv kev coj ua engineering. Rigid blast-cov qhov rooj tiv thaiv ncaj qha dais shockwave loads los ntawm siab- lub zog cov qauv los khaws cov airtight kev ncaj ncees ntawm cov khoom sib cais. Lub qhov rooj qhib qhov rooj siab siab tso siab rau cov khoom tsis muaj zog prearranged kom paub cov kev taw qhia siab venting thiab tiv thaiv lub tsev loj. Ob hom txais kev tsim qauv kev xav sib txawv kiag li thiab tsis hloov pauv tau.
Kev piav qhia ntawm Blast Doors Classified by Protection Mechanism
Muab faib los ntawm kev tiv thaiv mechanism, blast qhov rooj rau kev lag luam thiab pej xeem huab cua tiv thaiv kev siv poob rau hauv peb pawg tseem ceeb: rigid blast- hom resistant, hom nyem nyem thiab airtight hom. Peb hom sib txawv hauv cov ntsiab lus tseem ceeb ntawm kev tiv thaiv kev tiv thaiv thiab kev quab yuam- lub hauv paus ntsiab lus ntawm kev ua haujlwm, nrog rau cov kev ua haujlwm sib txawv, ua lub hauv paus tseem ceeb rau kev xaiv hom phiaj xwm thiab kev tsim qauv. Cov lus qhia ntxaws ntxaws tau muab raws li hauv qab no.
1. Rigid Blast-Resistant Blast Door (High Load-Bearing & Rigid Resistance Mechanism)
Nws txoj hauv kev tiv thaiv tseem ceeb yog kev ua haujlwm tsis zoo, ua rau nws yog thawj cov khoom tiv thaiv rau siab - ib puag ncig txaus ntshai. Tsim los nrog ib qho tseem ceeb siab - lub zog steel ncej thiab kev sib koom ua ke anchoring system, nws tsis cia siab rau lub siab nyem lossis deformation buffering. Hloov chaw, nws tiv thaiv thiab tiv thaiv kev tawg overpressure nkaus xwb los ntawm nws cov ultra- siab structural zog thiab tag nrho stability. Nyob rau hauv lub moj tej tawg cuam tshuam loads, lub qhov rooj tseem nyob tsis muaj deformation los yog puas txhua lub sij hawm, tuav nruj sealing ntawm lub qhov rooj nplooj thiab ncej. Nws tag nrho thaiv sab hauv kev nthuav tawm ntawm shockwaves, fragments thiab siab -kub flue gas. Ua tsaug rau nws qhov kev ua haujlwm zoo tshaj plaws, nws tau siv dav hauv cov cheeb tsam tseem ceeb nrog cov kev xav tau nruj rau cov qauv kev nyab xeeb thiab kev tiv thaiv kev ruaj ntseg, xws li siab -kev pheej hmoo tawg- cov khoom tiv thaiv, cov chaw nkaum hauv av, cov khoom tswj cov chav thiab cov chaw ua tub rog phom sij.
2. Lub Rooj Tswjhwm Saib Xyuas Kev Ruaj Ntseg Qhov Ncauj (Directional Pressure Venting & Load Reduction Mechanism)
Txais kev siv lub zog taw qhia lub zog tso tawm logic, nws txawv kiag li los ntawm kev ua haujlwm tsis zoo ntawm lub qhov rooj tsis sib haum. Nruab nrog ua ntej- teeb tsa lub siab nyem lub zog, lub siab no - cov qauv kev tiv thaiv rhiab tau teeb tsa nrog tus qauv kev nyab xeeb siab pib. Thaum ib qho kev tawg hauv tsev thawb lub siab sab hauv mus txog qhov pib ua ntej, cov khoom siv nyem qhib tau nyob rau hauv qhov kev taw qhia ruaj khov kom nrawm nrawm nrawm nrawm thiab siab - cov pa roj tawm sab nraud. Qhov no zoo dissipates peak blast lub zog thiab drastic txiav tej yam loads exerted rau lub ntsiab lub tsev, phab ntsa, kab teeb thiab kab, tiv thaiv lub cev qhuav dej los yog kev puas tsuaj ntawm lub tsev qauv. Nws tsis xav tau ultra-siab rigidity, nrog nws cov haujlwm tseem ceeb tau txo qis los tiv thaiv cov qauv tseem ceeb. Li no nws yog feem ntau ntsia rau ntawm phab ntsa sab nraud ntawm cov nroj tsuag dav dav, cov yeeb nkab dav dav thiab cov chaw ua haujlwm zoo tib yam uas tau muab qhov tseem ceeb rau kev tiv thaiv lub tsev qauv.
3. Airtight Blast Door (Multi-Functional Composite Protection Mechanism)
Raws li cov khoom siv tiv thaiv sib xyaw, nws ua ke nrog peb qhov kev ua yeeb yam tseem ceeb: blast tsis kam, huab cua nruj thiab cov pa phem cais tawm, xa cov kev tiv thaiv zoo raws li hnyav tshwj xeeb siab - kev pheej hmoo ua haujlwm. Thaum muaj peev xwm tiv taus cov pa tawg shockwaves, nws muaj tag nrho - ib puag ncig siab - cov qauv kev sib khi ua kom haum nrog kev laus - tiv thaiv sealing strips kom ua tiav nruj ntawm lub qhov rooj thiab ncej. Nws zoo tiv thaiv permeation ntawm cov pa phem thiab cov pa phem, xov xwm thiab soot rau hauv qhov chaw tiv thaiv. Kev sib txuas cov qauv kev tiv thaiv kev sib tsoo thiab kev sib cais ib puag ncig, nws yog siv rau cov chaw uas muaj cov qauv nruj rau huab cua nruj, kev nyab xeeb thiab kev tiv thaiv kev phom sij, suav nrog kev tiv thaiv huab cua hauv huab cua thaum ua tsov ua rog, underground thee thee mine retention chambers, chemical workshops produces toxic media and hazardous gas storage area.
