Nyob hauv ntau lub chaw ua haujlwm, chaw ua haujlwm, tsev noj mov lossis lwm qhov chaw pej xeem, koj tuaj yeem nrhiav tau lub pa taws. Nws yog tsim los tua hluav taws sai sai, muaj kev tiv thaiv hluav taws ntau ntxiv thiab tau nruab rau hauv cov pa taws. Kab lus no yuav piav qhia luv luv txog nws cov qauv tsim, khoom siv thiab daim ntawv thov. Tsis tas li ntawd, nws yuav tsis ua yam tsis tau hais txog qhov tsis ua haujlwm tseem ceeb ntawm cov khoom siv tau nthuav tawm.
DVS valve
DVS chav kawm hluav taws kub hnyiab tau siv los tshem tawm cov khoom siv hluav taws xob sai sai ntawm chav tsev. Xws li li qub tsuas yog ntsia tau rau hauv cov pa taws. Nyob rau hauv lub xeev tus qauv, lub damper hniav hom (W) nyob rau hauv qis txoj hauj lwm thiab tsis tso cai rau huab cua mus faib thoob plaws hauv lub system. Yog tias hluav taws tawg hauv ib chav, lub damper nyob rau hauv nruab nrab ntawm lub hearth qhib thiab, nrog kev pab los ntawm huab cua cua, tshem tawm tag nrho cov pa luam yeeb, yog li tiv thaiv hluav taws nyob rau hauv lwm chav. Qhov hluav taws kub tsis kam ntawm cov pa luam yeeb li qub yog mus txog 180 degrees. Qhov noqhov taw qhia pab xam lub sijhawm uas lub valve poob nws qhov nruj. Cov tsos ntawm lub valve nyob ntawm tsis tsuas yog nyob rau ntawm qhov chaw uas nws yuav raug ntsia, tab sis kuj nyob rau hauv tej yam kev mob ntawm nws installation. Xws li li qub tuaj yeem ua tau ntau yam:
- Caij nplooj ntoos hlav tsav nruab nrog electromagnetic puag.
- Electromechanical actuators tsis muaj caij nplooj ntoos hlav.
Installation
Kev txhim kho cov pa taws valve tsis yog ua los ntawm cov pa cua thiab hauv cov chav uas nyob hauv qeb "A" thiab "B" rau kev nyab xeeb hluav taws. Tsis tas li ntawd, lawv tsis yog tsim los rau cov qauv txheej txheem hoods, qhov twg ntau yam flammable tshuaj raug tshem tawm.
Cov pa luam yeeb dampers tsuas yog ntsia tau rau hauv cov tshuab uas siv cov khoom siv hluav taws xob tsis tu ncua thiab lubricating deposits. Kev teeb tsa ntawm cov cuab yeej no tsuas yog ua tiav yog tias tag nrho cov xwm txheej ntawm "BOS" (kev nyab xeeb ntawm qhov chaw tsim kho) tau ua tiav. Qhov hluav taws kub tsis kam ntawm cov pa luam yeeb damper web yuav tsum sib haum rau qhov hluav taws kub tsis kam ntawm tag nrho cov qauv uas nws tau nruab. Thaum pib ntawm lub installation, nws yog ib qho tsim nyog yuav tau kho lub valve lub cev (zoo dua nrog txhua yam khoom ntoo). Qhov no yog qhov tsim nyog txhawm rau txhawm rau txhawm rau tiv thaiv kev cuam tshuam ntawm cov qauv thiab ua txhaum ntawm qhov pib ntawm lub cev, uas tuaj yeem ua rau slamming ntawm nplooj, thiab vim li ntawd, kev ua haujlwm ntawm lub valve yuav raug cuam tshuam zoo heev. Tom qab cov cuab yeej tau muab tso rau hauv cov phab ntsa hluav taws, cov spacers tuaj yeem raug tshem tawm. Thiab tsuas yog tom qab lub valve yog grounded thiab hluav taws xobhlau nplaum, koj tuaj yeem sim.
Tsim
Galvanized steel yog siv los ua rooj plaub. Rau lub valve, nyob ntawm seb nws hom, siv phab ntsa lossis channel mechanism, uas yog nruab nrog ob lub flanges. Kuj tseem muaj ob hom kev tswj hwm:
- Electromagnetic. Nrog rau qhov kev tswj no, lub valve nkag mus rau hauv hom qhib tsuas yog thaum qhov hluav taws xob cuam tshuam nrog electromagnet. Thiab tsuas yog tom qab ntawd qhov hloov pauv cuam tshuam lub voj voog thiab tshem tawm cov electromagnet ntawm lub network. Lub sijhawm ntawm lub tshuab hluav taws xob yog tsawg dua 12 vib nas this. Txhawm rau teeb tsa hom kev ruaj ntseg, koj yuav tsum manually hloov txoj haujlwm ntawm rab rawg. Rau qhov kev sim tom ntej ntawm chav tsev, muaj cov zaub nrog lub pob ntawm lub valve.
- Belimo hluav taws xob tsav. Cov dampers nyob rau hauv cov ntaub ntawv no ua hauj lwm cia li nrog ib tug tas mus li voltage mov rau hluav taws xob tsav. Thaum lub tswb hluav taws tau qhib, cov pa luam yeeb valve tsav tau tag nrho de-energized thiab lub caij nplooj ntoos hlav rov qab lub valve mus rau qhov qhib. Ib pab pawg neeg tshwj xeeb tau tsim rau kev tsav hluav taws xob, uas tau teb sai sai rau nws txoj haujlwm. Ntxiv nrog rau kev tswj tsis siv neeg, koj tuaj yeem siv cov txheej txheem phau ntawv, kho lub valve nws tus kheej hauv txoj haujlwm tsim nyog. Txhawm rau ua qhov no, npaj rau ntawm tus yuam sij hex.
Valve failure
Txhua lub cav muaj lub kaus mom tiv thaiv dej. Lawv pab kaw qhov sib koom ua ke thiab coj tsis tau tsuas yog cov bushings, tab sis kuj cov pa luam yeeb valve nws tus kheej. Cov cuab yeej no muaj cov ntsaws ruaj ruaj. Nws yog lawv leej twg yuav tsum hermeticallytuav tus pas nrig thiab hatch lub pa taws valve. Sij hawm dhau mus, ntug hnav tawm thiab cov roj hmab ib ncig ntawm nws ua tsis tshua muaj elastic. Ces tej zaum yuav muaj pa luam yeeb. Nyob rau hauv cov ntaub ntawv no, nws yog tsim nyog los hloov tsis tau tsuas yog cov pa luam yeeb valve hatch, tab sis kuj tag nrho cov qauv uas nyob rau hauv nws.
