Pneumatic pob valve yog hloov zuj zus los ntawm ntsaws valve. Nws muaj tib qhov kev ua ntawm rotating 90 degrees, tshwj tsis yog tias lub cev nqaij qaib yog ib tug kheej kheej nrog ib ncig ntawm lub qhov los yog channel los ntawm nws axis. Qhov sib piv ntawm lub ntsej muag kheej kheej rau qhov qhib channel yuav tsum yog qhov uas thaum lub pob tig 90 degrees, txhua qhov chaw kheej kheej yuav tsum muaj nyob rau ntawm qhov nkag thiab qhov hluav taws xob, yog li txiav qhov ntws. Hom valve no tuaj yeem ntsia tau rau txhua qhov chaw hauv cov kav dej. Tom qab piav qhia lub tswv yim, cia Zhejiang Shuangzhong Tsis Siv Neeg Tswj Valve Co., Ltd. tham txog txoj hauv kev ua haujlwm thiab qee qhov zoo ntawm pneumatic pob valve.
Lub pneumatic pob valve tsuas yog yuav tsum siv lub pneumatic actuator los tsav lub valve lub cev kom tig 90 degrees kom paub txog kev ua haujlwm ntawm kev txiav tawm thiab qhib qhov ntws ntawm qhov nruab nrab. Thiab nws tsuas yog xav tau me me tig torque kom kaw nruj nreem. Qhov sib npaug tag nrho lub cev kab noj hniav ntawm lub valve lub cev muab qhov tsis muaj kev tiv thaiv thiab txoj hauv kev ncaj nraim rau qhov nruab nrab. Nws feem ntau suav hais tias lub pob valve yog qhov tsim nyog tshaj plaws rau kev qhib ncaj qha thiab kaw, tab sis tsis ntev los no cov kev tsim kho tau tsim lub pob valve kom nws tuaj yeem siv rau throttling thiab ntws tswj. Cov yam ntxwv tseem ceeb ntawm lub pob valve yog nws cov qauv kev cog lus, kev ua haujlwm yooj yim thiab kev saib xyuas, haum rau kev ua haujlwm dav dav xws li dej, hnyav, kua qaub thiab nkev, thiab tseem tsim nyog rau kev tshaj tawm nrog kev ua haujlwm hnyav, xws li oxygen, hydrogen peroxide, methane thiab ethylene. Lub pob valve lub cev tuaj yeem ua ib qho lossis ua ke.
Nyob rau hauv cov kav dej, nws yog siv los txiav tawm ceev ceev, faib thiab hloov cov kev taw qhia ntws ntawm qhov nruab nrab. Nws yog ib hom tshiab valve uas tau siv dav hauv xyoo tas los no. Nws muaj qhov zoo hauv qab no:
1. Cov dej tsis kam yog me me, thiab nws cov coefficient kuj yog sib npaug rau cov yeeb nkab seem ntawm tib qhov ntev.
2. Cov qauv yooj yim, me me, thiab lub teeb yuag.
3. Tight thiab txhim khu kev qha. Tam sim no, sealing nto khoom ntawm lub pob li qub yog dav siv yas, uas muaj kev sib khi zoo thiab kuj tau siv dav hauv lub tshuab nqus tsev.
4. Yooj yim rau kev khiav lag luam, qhib thiab kaw sai, tsuas yog tig 90 degree los ntawm kev qhib siab kom kaw tag nrho, uas yooj yim rau kev tswj kev mus ntev.
5. Kev saib xyuas yog yooj yim, cov qauv yog yooj yim, lub nplhaib sealing feem ntau yog txav tau, thiab lub disassembly thiab hloov tau yooj yim dua.
6. Thaum qhib tag nrho los yog kaw tag nrho, lub sealing nto ntawm lub pob thiab lub rooj zaum valve raug cais tawm ntawm qhov nruab nrab, thiab thaum qhov nruab nrab hla dhau, nws yuav tsis ua kom yaig ntawm lub valve sealing nto.
7. Kev siv ntau yam, txoj kab uas hla ntawm me me mus rau ob peb millimeters, loj mus rau ob peb meters, thiab tuaj yeem siv los ntawm lub tshuab nqus tsev mus rau qhov siab.
8. Vim tias lub zog hluav taws xob yog roj, qhov siab feem ntau yog 0.2-0.8MPa, uas yog qhov zoo. Yog tias muaj huab cua tawm, piv nrog hydraulic thiab hluav taws xob, cov roj tuaj yeem raug tso tawm ncaj qha, uas tsis muaj kuab paug rau ib puag ncig, thiab muaj kev nyab xeeb siab nyob rau tib lub sijhawm.
9. Piv nrog phau ntawv thiab turbo-rotating pob li qub, nws tuaj yeem teeb tsa nrog cov kab loj loj (cov phau ntawv thiab turbo-rotating pob li qub feem ntau qis dua DN300 caliber, thiab tam sim no tuaj yeem ncav cuag DN1200 caliber.)
Nws tau siv dav hauv roj av, tshuaj lom neeg kev lag luam, tsim hluav taws xob, papermaking, atomic zog, aviation, foob pob hluav taws thiab lwm yam haujlwm, nrog rau tib neeg lub neej txhua hnub.
