Flanged li qub yog kaw-tawm li qub, kev siv uas tau dhau los ua kom yooj yim thiab yooj yim uas nrog lawv cov tsos cov li qub tau poob qis heev.
Txoj kev sib txuas thiab kav dej
Qhov kev faib tawm tseem ceeb ntawm qhov haum yog raws li txoj kev sib txuas. Muaj kev sib txuas, welded, flanged thiab haum. Flanged li qub feem ntau yog siv nyob rau hauv rooj plaub uas nws yog ib qho tsim nyog rau nruab kaw-off li qub rau ntawm cov kav dej. Cov kab ke ntawm hom no suav nrog cov hauv qab no:
- pipelines rau lub hom phiaj hauv nroog;
- roj hloov tshuab;
- roj pipelines;
- cua txias thiab compressed cua networks;
- gas pipelines.
Ntxiv rau, flanged li qub tau nquag siv hauv kev lag luam xws li kev ua liaj ua teb thiab kev tsim nkoj.
Txoj kev faib tawm
Lub ntsiab tseem ceeb ntawm lub kaw-off valve yog lub pob-qhov rooj. Hauv seem no kuj muaj ib lub qhov ntawm square thiab round seem. Txhawm rau txhim kho lub valve hauv faucet, ntau yam fasteners thiab gaskets yog siv los tsim kom nruj. Fastening tib yamyog nqa tawm ncaj qha mus rau lub crane, nrog kev pab los ntawm cov ndlwg ntawm qhov nruab nrab ua hauj lwm tom qab tswj. Lub flange valve tsuas muaj ob txoj haujlwm thiab tuaj yeem qhib tag nrho lossis kaw tag nrho.
Tam sim no, xws li fittings yog tsim nrog ntau yam ntawm txoj kab uas hla - los ntawm 15 hli mus rau 1400 hli. Txawm li cas los xij, feem ntau, kev siv lub crane yog siv rau thaum txoj kab uas hla ntawm lub raj xa dej yog 50 hli lossis ntau dua.
Ntxiv mus, nws yuav tsum tau muab sau tseg tias qhov chaw ntawm lub pob tuaj yeem muaj ob txoj hauv kev, uas nyob ntawm txoj kab uas hla ntawm lub valve. Yog hais tias lub cuab yeej muaj tus nqi me me, ces lub pob yog ntab. Yog tias qhov ntsuas siab tshaj 50 mm, ces lub pob raug kaw rau ntawm qhov kev txhawb nqa. Nws tseem tsim nyog ntxiv tias qhov tshwj xeeb ntawm steel flanged li qub yog tias lawv muaj lub zog siab heev, uas tso cai rau lawv ua haujlwm hauv qhov chaw siab.
Ntau yam khoom tshwj xeeb
Txij li txhua yam khoom siv yuav tsum tau kho, cranes kuj tau muab faib ua ob pawg raws li txoj kev nws ua. Thawj pab pawg yog cov khoom siv tsis sib cais uas muaj cov khoom pov tseg ib lub cev. Yog tias lawv ua tsis tiav, lawv tsis tuaj yeem kho, nws yog qhov tsim nyog los hloov cov fittings mus rau ib qho tshiab. Cov pab pawg thib ob yog collapsible locking qhov chaw, muaj ob qhov chaw txuas rau hauv ib lub cev. Nws tsis yooj yim rau disassemble nws, thiab yog li nws muaj peev xwm hloov tau tsuas yog hnav cov khoom, thiab tsis yog tag nrho cov armature.
Tsis tas li ntawd, kev faib tawm kuj tau ua raws li cov chav kawm tsav tsheb,uas yog siv nyob rau hauv lub ntaus ntawv. Standard qauv muaj ib tug phau ntawv gearbox. Tom ntej no tuaj cranes nrog hluav taws xob tsav, txawm li cas los xij, yuav tsum muaj kev txhawb nqa ntxiv rau lawv qhov kev teeb tsa. Qhov thib peb yog pneumatically actuated fittings. Lwm tus yam ntxwv tseem ceeb yog qhov kev hla ntawm qhov chaw ua haujlwm. Ib nrab bore qauv muaj uas tso cai rau 50% ntawm cov xov xwm dhau los. Hom qauv dhau los ntawm 70 mus rau 80%. Tag nrho cov qauv - ntau tshaj 90% ntawm cov khoom.
Flanged pob valves nqi
Ib txwm, tus nqi ntawm cov khoom siv no nyob ntawm lawv tus yam ntxwv, nrog rau cov chaw tsim khoom. Piv txwv li, kaw-off li qub nrog ib txoj kab uas hla ntawm 100 mm raug nqi txog 3,500 rubles. Txawm li cas los xij, nws muaj cov yam ntxwv hauv qab no:
- Tus nqi ntawm flanged li qub yog nyob ntawm seb hom nruab nrab koj yuav tsum ua haujlwm nrog: dej, cua, roj khoom, roj thiab roj nplua nyeem, nrog rau cov kua uas tsis muaj cov khoom tsis huv.
- Lub siab ua haujlwm hauv cov kais dej no tuaj yeem ncav cuag 1.6 MPa.
- Qhov siab tshaj plaws ntawm qhov ua haujlwm nruab nrab yog 200 degrees Celsius.
Cov qauv no yog tsim nyob rau hauv Russia, lawv qhov hnyav yog li 13 kg. Muaj zoo li flanged pob li qub, tus nqi ntawm uas yog hais txog 3,400 rubles. Lawv yog tsim los ntawm Tsis tas li ntawd, kuj nyob rau hauv Russia. Yog hais tias peb tham nyob rau hauv dav dav txog qhov sib txawv ntawm tus nqi, ces tus nqi ntawm xws li ib tug crane pib los ntawm 3,300 thiab tuaj yeem ncav cuag 44,000 rubles.
Khoom siv,kev teeb tsa thiab kev ua haujlwm
Cam khwb cia hlau, tooj dag, tooj dag, stainless hlau tuaj yeem siv los ua cov khoom siv raw rau kev tsim cov khoom siv no. Yog tias peb tham txog kev ua haujlwm ntawm cov khoom siv no, ces lawv tsuas yog siv tau qhov twg nws yog qhov tsim nyog los hla lossis thaiv qhov ntws ntawm cov khoom ua haujlwm. Cov khoom siv no tsis tuaj yeem siv los ua tus tswj hwm. Thaum lub sij hawm installation txheej txheem ntawm 100 hli flanged pob valve los yog lwm yam, nws yog ib qho tseem ceeb uas yuav tau xav txog ntau yam tsis.
- Valve control type and piping type.
- Kev taw qhia ntawm kev tso lub network - kab rov tav lossis ntsug.
Yuav kom ua tiav qhov kev teeb tsa ntawm lub crane, nws yog ib qho tsim nyog yuav tsum ua ob peb kauj ruam:
- Ua ntej yuav mus rau qhov kev teeb tsa, koj yuav tsum ua kom tiav kev kho dua tshiab ntawm lub cuab yeej. Nws yog ib qho tseem ceeb uas lub twj paj nruag tsis puas nyob rau hauv ib txoj kev.
- Tom ntej no, koj yuav tsum kuaj xyuas lub valve thiab cov kav dej kom zoo li qhov kev sib tw.
- Kev teeb tsa ncaj qha ntawm fittings yog ua los ntawm cov yeeb nkab flanges. Yuav tsum siv cov ntsaws ruaj ruaj.
- Ua ntej pib nrog kev txhim kho ntawm qhov cuab lub zog, nws tseem ceeb heev uas yuav tsum ua kom tiav axial alignment. Hauv lwm lo lus, nws yog ib qho tsim nyog yuav tsum ceev cov bolts kom sib npaug li ua tau nyob ib puag ncig tag nrho.
Cov Cai Siv
Muaj ob peb txoj cai yooj yim ua raws thaum ua haujlwm cov khoom siv no.
Ua ntej, nws yog ib qho tseem ceeb kom tsis tu ncua xyuas lub 80 mm flanged valve los yog lwm yam. Qhov zaus ntawm hom kev tshuaj ntsuam no nyob ntawmkev ua haujlwm thiab ib puag ncig ua haujlwm. Txawm li cas los xij, lub sijhawm sib txawv nyob rau hauv ib qho xwm txheej tsis tuaj yeem ntau dua 6 lub hlis.
Thib ob, yog tias lub valve yuav luag ib txwm ua haujlwm hauv ib txoj haujlwm, uas yog, nws yeej ib txwm qhib lossis kaw, tom qab ntawd nws yuav tsum tau hloov nws txoj haujlwm ib ntus. Cov txheej txheem no yuav tiv thaiv cov tsos ntawm deposits nyob rau saum npoo ntawm lub spherical structural element, uas yuav ua rau kom nws lub neej kev pab cuam. Cov hauj lwm no yuav tsum tau ua ob mus rau plaub zaug hauv ib xyoos.
Pros, cons and reviews
Ntawm qhov tsis xav tau qhov zoo, nws tsim nyog hais txog qhov muaj kev ntseeg siab thiab yuav luag tiav ntawm qhov xav tau kev saib xyuas tas li. Kuj tseem ceeb yog qhov tsis tshua muaj kev tiv thaiv hydraulic txaus thiab muaj peev xwm kaw tag nrho cov khoom ntws.
Qhov tsis zoo suav nrog qhov tseeb yog tias qhov no yog hom phau ntawv, ces nws muaj qhov ntev ntev, uas yuav tsum tau coj mus rau hauv tus account thaum lub sijhawm teeb tsa. Nws tseem tsim nyog hais tias qhov hnyav ntawm flanged li qub yog qhov loj heev.
Raws li kev tshuaj xyuas ntawm cov khoom no, lawv feem ntau yog qhov zoo. Cov tuam txhab xws li Bugatti, FAR, Oventrop tau txais kev lees paub zoo tshaj plaws ntawm cov neeg yuav khoom. Cov tuam txhab lag luam no tau tsim lawv cov khoom lag luam ua ib qho kev ntseeg siab tshaj plaws. Qee qhov kev tshuaj xyuas tsis zoo yog feem ntau yog vim qhov tseeb tias cov khoom tau yuav nrog cov khoom tsis zoo. Qhov teeb meem feem ntau yog cov hlau uas ua rau lub faucet.
