1. daim npav lub tes tsho hom mos sealing ntsaws valve sealing yog ua los ntawm sealing nto nyob ib ncig ntawm daim ntawv teev, qhov tshwj xeeb 360 ° hlau di ncauj tiv thaiv daim npav tas;
2. Lub valve tsis muaj kab noj hniav los sau cov xov xwm;
3. Cov di ncauj hlau muab kev ua haujlwm ntawm tus kheej hauv cov txheej txheem spinning, uas yog tsim rau cov viscous thiab yooj yim fouling tej yam kev mob;
4. Ob txoj kev ntws, nws yooj yim dua rau kev siv installation;
5. Cov khoom siv thiab flange qhov ntev ntawm cov khoom tuaj yeem raug xaiv raws li cov kev ua haujlwm tiag tiag lossis cov neeg siv cov kev xav tau, thiab ua tau raws li txhua yam kev xav tau ntawm engineering.
Newsway Valve tuam txhab ntsaws valve yog lub teb valve nrog lub kaw los yog lub plunger.Los ntawm kev tig 90 degrees, qhov chaw nres nkoj ntawm lub valve ntsaws yog sib txuas lus lossis sib cais nrog cov chaw nres nkoj ntawm lub valve lub cev kom paub qhib lossis kaw.
Nws lub pob valve tuaj yeem ua cylindrical lossis conical.Hauv cylindrical valve plugs, cov channel feem ntau yog cov duab plaub;Nyob rau hauv conical valve plugs, cov channel yog trapezoidal.Cov duab no ua rau cov qauv ntawm lub ntsaws valve sib zog.Nws yog qhov tsim nyog tshaj plaws raws li kev txiav tawm thiab kev sib txuas nruab nrab thiab shunt, tab sis nyob ntawm cov khoom siv thiab kev yaig tsis kam ntawm qhov sealing nto, qee zaum nws tuaj yeem siv rau throttling.
Cov ntsaws li qub tau muab cais raws li kev siv: mos foob ntsaws li qub, roj lubricated nyuaj foob ntsaws li qub, nqa ntsaws li qub, peb-txoj kev thiab plaub-txoj kev ntsaws li qub.
Cov ntsaws ntsaws ntsaws ruaj ruaj feem ntau yog siv rau hauv qhov chaw hnyav xws li corrosive, muaj kuab lom thiab muaj kev phom sij ntau, qhov kev xau yog nruj me ntsis txwv tsis pub, thiab qhov twg cov khoom siv valve tsis muaj kuab paug tawm.Lub valve lub cev tuaj yeem xaiv los ntawm cov hlau, hlau alloy thiab stainless hlau raws li qhov nruab nrab ua haujlwm.
Lubricated nyuaj foob ntsaws li qub tuaj yeem muab faib ua cov pa roj lubricated ntsaws li qub thiab siab sib npaug ntsaws li qub.Cov roj tshwj xeeb yog txhaj los ntawm sab saum toj ntawm lub plug lub cev ntawm lub khob hliav qab lub qhov ntawm lub valve lub cev thiab lub plug lub cev los tsim cov roj zaj duab xis kom txo tau qhov qhib thiab kaw lub zog ntawm lub valve thiab txhim kho kev sib khi thiab kev pabcuam lub neej.Kev ua haujlwm siab tuaj yeem ncav cuag 64MPa, qhov siab tshaj plaws ua haujlwm tuaj yeem ncav cuag 325 degrees, thiab qhov siab tshaj plaws txoj kab uas hla tuaj yeem ncav cuag 600mm.
Lifting plug li qub muaj ntau hom qauv.Thaum lub valve qhib, lub ntsaws yog tsa, thiab lub ntsaws yog tig 90 degrees mus rau tag nrho qhib lub valve kom txo tau qhov kev sib txhuam nrog sealing nto ntawm lub valve lub cev;Thaum lub valve kaw, lub ntsaws yog tig 90 degrees mus rau qhov chaw kaw.Poob mus cuag lub sealing nto ntawm lub valve lub cev kom ua tiav sealing.
Peb-txoj kev thiab plaub-txoj kev stopcocks yog tsim rau kev hloov nruab nrab ntws kev taw qhia los yog rau nruab nrab tis.Raws li cov kev xav tau ntawm kev ua haujlwm, koj tuaj yeem xaiv mos sealing bushing lossis mos sealing, nyuaj sealing nqa ntsaws valve.
