Qauv
Daim ntawv thov
▪ Lub telescopic npauj npaim li qub siv telescopic roj hmab sealing qauv, muaj feem xyuam rau metallurgy, petrochemical, hydropower, tshuaj, lub teeb textile, ntawv ua, nkoj, roj, dej thiab dej, thiab lwm yam pipeline systems raws li ib tug telescopic sealing kaw muaj nuj nqi.
Cov lus qhia
▪ Telescopic npauj npaim valve yuav tsum muab tso rau kab rov tav.Tsis txhob tsoo nws ntawm kev xav.
▪ Thaum lub telescopic npauj npaim valve tawm ntawm lub Hoobkas, qhov ntev ntawm cov qauv yog qhov tsawg kawg nkaus.Thaum lub sij hawm installation, nws yuav tsum tau rub mus rau lub installation ntev (piv txwv li qhov tsim ntev).
▪ Thaum qhov ntev ntawm cov kav dej ntau tshaj qhov ntev ntawm lub telescopic npauj npaim valve, thov kho qhov sib nrug ntawm cov yeeb nkab.Tsis txhob yuam rub lub telescopic valve kom tsis txhob muaj kev puas tsuaj.
▪ Lub telescopic npauj npaim valve tuaj yeem ntsia tau ntawm txhua txoj haujlwm.Rau kev them nyiaj kub, tom qab kev teeb tsa ntawm lub raj xa dej, lub bracket yuav tsum tau muab ntxiv rau ntawm ob qho kawg ntawm lub axis ntawm cov kav dej kom tsis txhob rub lub telescopic valve yeeb nkab (saib daim duab 1).Lub zog txhawb nqa ntawm lub bracket yuav tsum raug xam raws li cov qauv hauv qab no.Nws raug txwv nruj kom tshem tawm cov kev txhawb nqa thaum lub sijhawm ua haujlwm.
F>Ps·DN·(kgtf) Test: PS-pipe test siab DN-pipe txoj kab uas hla
▪ Nws yog txwv tsis pub kom disassemble lub expansion npauj npaim valve ntawm lub raj xa dej.
▪ Lub telescopic npauj npaim valve muaj kev ua haujlwm zoo thiab kev koom tes nruj.Tsis txhob ncab thiab luv luv lub telescopic npauj npaim valve dua ntawm qhov chaw.Thaum lub sij hawm installation, cov kav dej ntawm ob qhov kawg ntawm lub expansion valve yuav tsum yog concentric, thiab ob lub flange nto ntawm lub raj xa dej yuav tsum yog tib yam.
▪ Lub flange kho bolts yuav tsum fastened symmetrically.Tsis txhob yuam kom flange kho bolts unilaterally.
▪ Cov yeeb nkab nthuav dav yuav tsum muab ntsia tom qab lub valve.
▪ Ib feem ntawm lub expansion npauj npaim valve yuav tsum tsis txhob muab ntsia rau ntawm lub ces kaum lossis qhov kawg ntawm cov yeeb nkab.
