Qhov zoo thiab qhov tsis zoo ntawm welded rooj vag valve thiab teeb meem xav tau kev saib xyuas hauv kev teeb tsa
Lub rooj vag valve yog qhov qhib thiab kaw qhov chaw ntawm lub rooj vag, kev taw qhia ntawm kev txav ntawm lub rooj vag thiab cov kev taw qhia ntawm cov kua dej yog ntsug, lub rooj vag valve tsuas yog qhib thiab kaw tag nrho, lub qhov rooj tsis sib txawv, feem ntau yog 5 °, nruab nrab kub tsis siab rau 2 ° 52 '.Txhawm rau txhim kho nws cov thev naus laus zis thiab tsim kom muaj qhov sib txawv ntawm lub sealing nto Lub kaum sab xis hauv cov txheej txheem ntawm kev ua, lub rooj vag zoo li no hu ua elastic rooj vag.Lub rooj vag li qub muaj flange rooj vag li qub, welded rooj vag li qub, lub hwj chim chaw nres tsheb rooj vag li qub,

Qhov zoo ntawm welded rooj vag valve:
Cov qauv yooj yim, kev tsim khoom thiab kev saib xyuas yooj yim dua.
Me me ua haujlwm stroke, luv qhib thiab kaw lub sijhawm.
Zoo sealing, me me kev sib txhuam ntawm sealing nto, lub neej ntev.
Disadvantages ntawm welded rooj vag valve:
Cov dej tsis kam yog loj, thiab lub zog yuav tsum tau qhib thiab kaw yog loj.
Nws tsis haum rau nruab nrab nrog granule, siab viscosity thiab coking yooj yim.
Kev tswj xyuas tsis zoo.
Hom welded rooj vag valve tau muab faib ua cov xov sab nraud thiab sab hauv xov hom raws li txoj haujlwm ntawm lub valve qia xov.Raws li kev khiav dej num ntawm qhov nruab nrab, muaj qhov ncaj-dhau, ncaj-ntws thiab lub kaum sab xis.Globe li qub tau muab faib ua cov ntaub ntawv sib khi, suav nrog cov ntim khoom hauv lub rooj vag li qub thiab lub tshuab nqus dej foob lub ntiaj teb li qub.
Kev ceev faj rau vuam rooj vag li qub:

1. Kev tuav tes, tuav thiab kev sib kis mechanism tsis pub siv rau kev nqa, thiab kev sib tsoo yog nruj me ntsis txwv.
2, ob chav disc lub rooj vag valve yuav tsum tau ntsia vertically (uas yog, qia nyob rau hauv txoj hauj lwm ntsug, handwheel nyob rau sab saum toj).
3, lub rooj vag valve nrog bypass valve yuav tsum qhib ua ntej qhib lub bypass valve (kom sib npaug ntawm qhov nkag thiab qhov hluav taws xob sib txawv thiab txo qhov qhib quab yuam).
4. Lub rooj vag valve nrog kev sib kis mechanism yuav tsum raug ntsia raws li cov lus qhia ntawm cov khoom.
5, yog tias lub valve feem ntau siv, tsawg kawg ib hlis ib zaug lubrication

Nortech yog ib qho ntawm cov ua lag luam valve manufacturers hauv Suav teb nrog cov ntawv pov thawj zoo ISO9001.
