Prection Valve VS Deluge Valve
Ua ntej-txiav txim valve thiab deluge valve yog ob hom kev siv hluav taws xob siv nyob rau hauv cov hluav taws tiv thaiv cov pa dej kom tswj tau cov dej rau cov kais dej. Thaum ob ob leeg li qub yog qhov tseem ceeb rau kev tswj hwm hluav taws, lawv muaj qhov sib txawv ntawm cov kev ua haujlwm thiab kev thov.
Pre-Action Valve yog hom ntawm valve uas yog tsim los tiv thaiv kev raug yuam kev ntawm cov dej hauv cov kais dej. Nws yuav tsum tau muaj ob qho kev sib cais los tso dej: Ua ntej, kev tshuaj xyuas ntawm cov hluav taws lossis pa taws los ntawm hluav taws tau cov kab ke, thiab qhov thib ob, kev ua kom muaj cov kais tsuag dej. Txoj kev kawm ob kauj ruam no pab kom txo cov dej puas tsuaj thaum muaj lub tswb cuav lossis kev puas tsuaj rau cov kais dej. Pre-nqis tes ua li qub yog siv nyob rau hauv thaj chaw nrog cov cuab yeej rhiab lossis cov khoom muaj txiaj ntsig uas xav tau kev tiv thaiv los ntawm cov dej puas.
Ntawm qhov tod tes, kho lub valve yog ib hom valve uas tso dej rau tam sim ntawd tom qab kev ua kom rov qab pom cov hluav taws. Nws yog feem ntau siv nyob rau thaj chaw muaj kev phom sij uas muaj cov dej ntau yog qhov xav tau los txhawm rau txhawm rau tshem tawm hluav taws sai. Cov chaw nyob qis yog pom muaj nyob hauv cov chaw muaj tshuaj, cov nroj tsuag tshuaj, thiab cov dav hlau uas nrawm thiab kev tiv thaiv hluav taws kub yog qhov tseem ceeb yog qhov tseem ceeb.
Tub Ntxhais Ua Haujlwm & Tsim Qauv
A. Pre-Action Valve: Dual-Action, Dej-tswj Tso Tawm
- Lub Hom Phiaj: Kev ua ntej ua ntej tau tsim rau cov chaw muaj dej, cov chaw khaws ntaub ntawv, tsev cia puav pheej tau rhuav tshem Irreplaceable cov peev txheej. Lawv xav tau ob qho xwm txheej ywj siab los tso dej:
- Nrhiav tau hluav taws kub (haus luam yeeb \/ cov ntawv pom cua sov ua rau muaj lub ntsej muag lossis hluav taws xob).
- Sprinkler kev ua kom muaj zog (kub-rhiab qhov sib tsoo tawg ntawm qhov kub me).
- Mechanism:
- Nquag kaw: lub valve ib lub valve tuav dej rov qab nyob rau hauv siab, nrog lub tshuab hluav taws xob tau sau nrog cov pa roj av lossis nitrogen (los saib xyuas kab).
- Ua ntej ua haujlwm:
- Kauj Ruam 1: Cov Hluav Taws Xob Hluav Taws Teeb Pom Lub Hom Phiaj Pre-Action qhib, Filling Kav Dej Nrog Dej.
- Kauj Ruam 2: Cov taub hau sprinkler ua kom ntau dua lossis sib npaug ntawm 135 degree f-165 degree f-165 degree f (57 degree -74 degree), tawm hauv dej hauv zos.
Cov khoom tseem ceeb:
- Pre-Manuale Valve (tsav diaphragm lossis deluge-style txiav).
- Saib xyuas lub siab hloov (los saib xyuas huab cua \/ dej siab).
- Lub tswb ceeb toom qis (rau cov yeeb nkab xau).
Muab ob npaug-sib txuas tswj (rau ntxiv kev nyab xeeb hauv cov ntawv thov tseem ceeb).
B. DELUGE VALOOS: Instantaneous, To-Dej Dag Zog
- Lub Hom Phiaj: Cov khoom siv dej ntshiab tau tso rau hauv cov chaw muaj phom sij, hluav taws xob ua kom muaj hluav taws kub uas muaj hluav taws xob nrawm ua ntej lawv escalate.
- Mechanism:
- Feem ntau kaw: lub deluge valve tseem kaw lub siab, nrog dej thaiv los ntawm ib lub hydraulic, pneumatic, lossis hluav taws xob kev siv hluav taws xob.
- Simmultaneous kev tshem tawm: Thaum kev ua kom qhib, tag nrho cov qhib-xaus rau hauv kev tiv thaiv tawm dej hauv tsawg dua los yog sib npaug thaj chaw rau thaj chaw rau cov nplaim taws smooth.
Qhov tseem ceeb:
- Lub ntsiab deluge deluge valve (ductile hlau \/ stainless hlau \/ stainless hlau \/ 10-300 psi ntsuam xyuas).
- Pilot Luas (solenoids, siab hloov chaw, kuaj xyuas li qub, lim).
- Saib Xyuas Lub Nrab (rau kev ua phem lossis tsis tshua muaj siab).
Cov Ntawv Thov & Siv Cov Kab Mob
A. Pre-Action Valve Applications
- Cov ntaub ntawv Chaw & Telecom Hubs:
- Tiv thaiv cov servers, cable, thiab cia khoom los ntawm dej puas.
- Dual-interlock Systems tiv thaiv kev raug yuam kev los ntawm cov hluav taws xob (piv txwv li, xob laim).
- Qhov chaw ua kev coj ua:
- Tsev khaws puav pheej, cov tsev khaws ntaub ntawv, thiab cov tshuab ua ntej rau kev tiv thaiv kev tiv thaiv kev ua yeeb yam, cov ntawv sau, thiab cov duab kos.
- Chaw kaw khoom txias:
- Tiv thaiv cov yeeb nkab khov los ntawm kev siv cov pa roj nitrogen hauv cov tshuab ua ntej (huab cua yuav ua kom khov thiab khov).
- Cov kev ua kom huv & Lub Chaw Haujlwm:
- Zam kev haus dej kom tsis txhob muaj cov dej sib kis nyob rau hauv sicishonductor fabrication lossis tshuaj tshawb xyuas.
B. Deluge Valve Kev Siv
- High-REEIGHE SYST TSA:
- Roj & Roj: Tiv thaiv cov liaj teb tank, flare stacks, thiab sab nrauv platforms los ntawm cov hluav taws kub hluav taws.
- Tshuaj Nroj Tsuag: Mitigates kev khiav tawm hauv kev tiv thaiv hauv cov kuab tshuaj lossis cov kab distillation.
- Kev Lag Luam & Tsheb Thauj Mus Los:
- Cov dav hlau HANGARS: Siv cov khoom siv ua npuas dej siab-dej ntshiab tshuab mus rau kev nce dav dav hlau roj.
- Ntau yam & subways: Dej nyab cov chaw dej nyab xeeb kom muaj cov hluav taws tsheb hauv tsheb.
- Lub zog tiam:
- Transformer yards: deluge tshuab txias roj nchuav kom tiv thaiv tawg.
- Cov chaw nuclear: muab cov thaub qab kev txhawb nqa rau cov pas dej roj.
