Lub rooj vag swb yog ib yam ntawm cov khoom siv tseem ceeb rau kev khiav lossis kev xa khoom ntawm cov khoom siv hmoov, cov khoom siv lead ua, cov khoom siv thiab cov khoom siv plua plav. Nws tuaj yeem ntsia tau rau hauv qis qis ntawm cov tshauv hopper xws li economizer, cua preheater, qhuav plua plav tshem tawm thiab flue hauv thermal fais fab nroj tsuag, thiab tuaj yeem siv nrog hluav taws xob feeder. Raws li cov ntaub ntawv sib txawv, qhov kub thiab txias kuj tseem txawv. Tus nqi sab hauv ntawm lub rooj vag swb: ≤ 1%; sab nraud to ntawm tus swb rooj vag valve yog xoom.

Lub rooj vag swb tuaj yeem muab faib ua hluav taws xob, pneumatic, electro-hydraulic thiab kev tuav haujlwm. Lub rooj vag swb valve txais yuav ib lub phaj tshwj xeeb, thiab lub sealing nto ntawm lub rooj vag valve yog ua tiav los ntawm kev xa thiab milling chips. Lub sealing qhov sib txawv me me thiab cov sealing kev ua tau zoo. Txoj kev sib txuas ntawm lub rooj vag swb thiab cov raj xa dej tuaj yeem yog flange bolt kev twb kev txuas lossis taub qab vuam txuas nrog cov kav dej.

1. Lub qhov rooj kaw qhov rooj kaw tau txais cov qauv kaw tag nrho. Tom qab lub disc qhib, nws yog nyob rau hauv lub kaw tu chav nyob rau sab nraud.

2. Lub rooj vag hluav taws xob hluav taws xob yog tsav los ntawm hluav taws xob actuator, tus ntsia hlau khub tig los tsim axial txav, thiab tom qab ntawd cov lus qhia tsav ntsia hlau lub tes tsho tsav lub plug-in disc txav mus, thiab lub plug-in phaj yog rub tawm los yog thawb rau hauv. ua kom tiav qhov qhib lossis kaw qhov kev txiav txim ntawm lub plug-in phaj, thiab kev ua haujlwm ruaj khov thiab txhim khu kev qha.

3. Lub pneumatic swb rooj vag valve yog muab tso rau hauv lub plhaub los ntawm qhov qhib thiab kaw lub tog raj kheej kom rub los yog thawb lub disc kom qhib lossis kaw.

4. Cov saw hlau zawv zawg yog ntsia rau ntawm ob sab ntawm lub plhaub kom txwv tsis pub zawv zawg phaj khiav hauv cov kev taw qhia rail. Nrog rau txoj kev tsim kho kom zoo, lub phaj zawv zawg txav tau yooj yim thiab yooj yim, thiab lub zog tsav tsheb me me.

5. Lub rooj vag swb tuaj yeem ua haujlwm remotely lossis tswj los ntawm kev pabcuam, nrog DCS chaw taws teeb tswj interface. Lub rooj vag hluav taws xob hluav taws xob yog nruab nrog Mechatronics hluav taws xob ntaus ntawv, uas tuaj yeem ua haujlwm hauv zos thiab nyob deb, thiab nruab nrog lub log ua haujlwm; lub pneumatic swb rooj vag valve yog nruab nrog lub tog raj kheej cua thiab tswj lub thawv, uas tuaj yeem ua haujlwm hauv zos thiab deb.

Thaum txiav txim lub rooj vag swb, nws yog ib qho tsim nyog yuav tsum qhia qhov ua haujlwm tsis zoo raws li hauv qab no:

1. Loj, ua haujlwm nruab nrab, nruab nrab ntws kev taw qhia

2. Qhov siab tshaj plaws ua haujlwm siab (P) Pa, siab tshaj plaws ua haujlwm kub (T) ℃

3. Pipeline kev taw qhia (kab rov tav / ntsug / inclined)

4. Yuav tsum qhib thiab kaw ceev

5. Kev teeb tsa qhov chaw (hauv tsev / sab nraum zoov)

6. Txoj kev ua haujlwm: hluav taws xob / pneumatic lossis phau ntawv

7. Txoj kev sib txuas nrog cov kav dej (vuam / flange txuas)

1. Hluav taws xob swb rooj vag valve

2. Pneumatic swb rooj vag valve

3. phau ntawv swb rooj vag valve
