Kaw-off valve rau cov dej mov: hom, yam ntxwv thiab lub hom phiaj

Kaw-off valve rau cov dej mov yog ib tug tshwj xeeb ntaus ntawv uas ua hauj lwm pab mus kaw tawm lub dej ntws ntawm ib tug tej yam feem ntawm lub system. Teem caij los ntawm muaj kev kho mob nroj tsuag thiab xaus tiaj tus.

Ib suam ntawm li qub

Qhov no armature muaj nyob rau hauv cov qauv ib tug txheej ntawm fasteners, assemblies, pab kiag li lawm, lub Cheebtsam, uas yog siv rau kev tswj cov ntau yam ntws. Cov nram qab no hais peev xwm yuav txawv ntawm lawv:

• li qub;
• li qub;
• cranes;
• kaw;
• li qub.

Lawv ntsia txawv kab, nyob rau hauv tej thiab nyob rau hauv cov chav nyob. Qhov kev txiav txim cov ntaub ntawv hais yog tsav los ntawm ib tug tshwj xeeb hluav taws xob pab kiag li lawm los yog manually. Muaj ob peb hom ntawm cov khoom xws li qub thiab fittings rau cov dej haus. Hom ntsiab yog muaj kev ruaj ntseg thiab nws.

General yam ntxwv ntawm li qub

Yuav tsum uas siv rau no hom ntawm cov khoom yuav tsum ua raws li cov nram qab no qauv:

• Khoom - dag, hlau, bronze, yas, cam khwb cia hlau.
• Txhua lub caij sau raws nkaus Ii mus rau lub tshwj xeeb kev khiav hauj lwm tej yam kev mob.
• Rate bandwidth yog siab txaus.
• Kaw-off valve rau cov dej mov yog tsim kom tau ib lub siab thiab kub.
• Nws yog ib qho tseem ceeb anticorrosive txheej, uas tiv thaiv corrosion.

Tsis txhob li qub: lub sij hawm

Qhov no cov khoom muaj nuj nqi ntawm ib tug muaj cim. Nrog nws yuav kiag li thaiv cov ndlwg ntawm gaseous los yog kua tshuaj. Kaw-off valve rau cov dej mov yog tam sim no heev. Nws yog los ntawm nws yog ua tau los muab ib tug ua tiav kev foob nyob rau hauv lub raj dej. Vodozapornaya fittings siv nyob rau hauv ntau yam teb, xws li dej, dej haus, cua sov tshuab.

Lub locking disc (rooj vag)

Tej yam analog armature muaj nyob rau hauv nws cov muaj pes tsawg leeg yog tswj thiab txhav tas disc. Feem ntau nws muaj peev xwm tig txog lub axis thiab ua perpendicular mus rau lub conduit, thiab qhov no qhia cem quav.

Xws li ib tug valve tswj manually los ntawm hluav taws xob tsav. Nyob rau hauv niaj hnub systems, piping cov ntaub ntawv drives yuav tswj tau remotely. Qhov no tso cai rau koj kom txhob khiav nyob rau hauv lub raj dej ntawm tej yam lub sij hawm. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm thaum muaj xwm ceev.

Log, uas yog txawm peem rau nrog li qub thiab fittings rau cov dej haus (cov duab yuav tau saib nyob rau hauv tsab xov xwm), yog cov feem ntau tseem ceeb. Lub tsuas disadvantage ntawm xws khoom yog lawv cov qib high kev daws teeb meem. Txawm li cas los, cov yam ntxwv xws li me ntsis kuj thiab simplicity ntawm tus tsim lub valve. Qhov no lub caij yog mounted los ntawm ib tug flange. Muaj ob peb hom ntawm disks: weld (tiaj tus los yog taub qab) thiab lub ntseg tsho.

Qhov tseem muaj txiaj ntsim nyob rau hauv lub tam sim no systems yog xav tau pob li qub, uas muaj ntau haum rau siv nyob rau hauv xws systems.

Kaw-off li qub

Kaw-off valve rau cov dej mov muaj tej yam hais, ib tug uas yog ib tug valve. Nws tsim yog txheej txheem thiaj li hais tias nws twb tau mus kiag thaiv cov dej txaus nyob rau hauv lub system. Lig xov yuav siv sij hawm ob txoj haujlwm: qhib thiab kaw. Muaj cov qauv ntawm cov qub los ntawm kev uas cov dej yog tom. Lawv ua tau ob zog ib txhij: nres thiab kev tswj.

Qhov zoo ntawm no hom yuav muaj raws li nram no:

• tiav ceev ceev;
• tau siv thaum muaj kev kub kub thiab pressures nyob rau hauv lub system;
• ib tug yooj yim kho thiab txij nkawm;
• Nws yuav ntsia tau rau hauv corrosivity, tshuab nqus tsev thiab corrosive ib puag ncig;
• ib theem siab ntawm durability.

Tsis zoo ntawm kaw-off li qub:

• hydraulic kuj yog loj txaus;
• nyob rau hauv ib txhia qhov chaw hauv dej mov system tej zaum yuav daig;
• rau cov kav dej nrog ib tug loj lub cheeb tsis tau ntsia.
