Kev faib tawm thiab kev ua haujlwm ntawm tus npauj npaim valve

Muaj ntau hom npauj npaim li qub, thiab muaj ntau txoj kev faib tawm.

1. Kev faib tawm los ntawm cov qauv tsim
(1)concentric npauj npaim valve; (2) ib leeg-eccentric npauj npaim valve; (3) ob-eccentric npauj npaim valve; (4) peb-eccentric npauj npaim valve

2. Kev faib tawm raws li cov khoom siv sealing
(1) Resilient npauj npaim valve
(2) Hlau-hom hard-sealed npauj npaim valve. Cov khub sealing yog tsim los ntawm cov khoom siv hlau nyuaj rau cov khoom siv hlau nyuaj.

3. Kev faib tawm los ntawm daim ntawv kaw
(1) Cov npauj npaim valve raug kaw.
(2) Siab sealing npauj npaim valve. Lub foob foob yog tsim los ntawm cov khoom siv elastic sealing ntawm lub rooj zaum lossis phaj.
(3) Tsis siv neeg kaw npauj npaim valve. Lub foob tshwj xeeb siab tau txais los ntawm qhov nruab nrab siab.

4. Kev faib tawm los ntawm kev ua haujlwm siab
(1) Lub tshuab nqus tsev npauj npaim valve. Npauj npaim valve nrog lub siab ua haujlwm qis dua li tus qauv huab cua.
(2) Tsawg-siab npauj npaim valve. Npauj npaim valve nrog lub nominal siab ntawm PN≤1.6MPa.
(3) Nruab nrab-siab npauj npaim valve. Lub nominal siab PN yog npauj npaim valve ntawm 2.5∽6.4MPa.
(4) Kev kub siab npauj npaim valve. Lub nominal siab PN yog npauj npaim valve ntawm 10.0∽80.OMPa.
(5) Ultra-siab siab npauj npaim valve. Npauj npaim valve nrog lub nominal siab PN <100MPa.

5. Kev faib tawm los ntawm hom kev sib txuas
(1)Npauj Npaim Valve
(2) Flange npauj npaim valve
(3) Npauj npaim valve
(4) Welded npauj npaim valve

2023.1.6 DN80 Wafer Npauj Npaim Valve nrog Ductile Iron + Plated Ni Disc --- TWS Valve

Concentric Npauj Npaim valve yog ib hom valve uas qhib thiab kaw nrog lub voj voog npauj npaim phaj thiab qhib, kaw thiab kho cov kua dej channel nrog kev sib hloov ntawm lub valve qia. Npauj npaim phaj ntawm npauj npaim valve yog ntsia rau hauv txoj kab uas hla ntawm cov yeeb nkab. Nyob rau hauv lub cylindrical channel ntawm npauj npaim valve lub cev, lub disc npauj npaim phaj rotates nyob ib ncig ntawm lub axis, thiab lub rotating lub kaum sab xis yog nyob nruab nrab ntawm 0 thiab 90. Thaum qhov kev sib hloov mus txog 90, lub valve yog qhib tag nrho.

Cov ntsiab lus tseem ceeb ntawm kev tsim kho thiab kev teeb tsa
1) Lub installation txoj hauj lwm, qhov siab, ntshuam thiab xa tawm kev taw qhia yuav tsum ua tau raws li cov qauv tsim, thiab kev sib txuas yuav tsum ruaj thiab nruj.
2) Tus kov ntawm txhua yam ntawm phau ntawv li qub ntsia rau ntawm cov yeeb nkab thermal rwb thaiv tsev yuav tsum tsis txhob poob qis.
3) Lub valve yuav tsum raug tshuaj xyuas sab nraud ua ntej kev teeb tsa, thiab lub npe ntawm lub valve yuav tsum ua raws li cov kev cai ntawm lub teb chaws tam sim no tus qauv "General Valve Mark" GB 12220. Rau li qub nrog kev ua haujlwm siab tshaj 1.0 MPa thiab txiav tawm ntawm lub ntsiab cov yeeb nkab, lub zog thiab kev ntsuas nruj yuav tsum tau ua ua ntej kev teeb tsa thiab yuav tsum tau siv tom qab tsim nyog. Hauv kev xeem lub zog, qhov ntsuas qhov siab yog 1.5 npaug ntawm lub siab nominal, thiab lub sijhawm tsis pub tsawg tshaj 5 feeb. Lub plhaub valve thiab ntim khoom yuav tsum tsim nyog yam tsis muaj qhov to. Rau qhov kev ntsuas nruj, qhov ntsuas siab yog 1.1 npaug ntawm lub siab nominal; Qhov kev sim siab yuav tsum ua tau raws li GB 50243 tus qauv rau lub sijhawm ntawm qhov kev xeem, thiab lub valve foob nto yog tsim nyog.

Cov khoom xaiv ntawm cov ntsiab lus tseem ceeb
1. Lub ntsiab tswj tsis tau ntawm npauj npaim valve yog cov specifications thiab qhov ntev.
2. Lub npauj npaim valve yog ib lub phaj cua valve, nws cov qauv yooj yim, kev ua haujlwm yooj yim, tus nqi qis, kev ua haujlwm yooj yim, tab sis qhov kev hloov kho tsis zoo, tsuas yog haum rau qhov cua thiab cua txias system rau kev hloov los yog ntxhib hloov ntawm lub ntees.
3. Yuav ua tau phau ntawv, hluav taws xob lossis zipper hom kev ua haujlwm, tuaj yeem kho tau ntawm txhua lub kaum sab xis ntawm 90 ntau yam.
4. Vim yog ib qho axial ib leeg valve phaj, cov kabmob quab yuam yog txwv, nyob rau hauv cov xwm txheej ntawm qhov sib txawv ntawm lub siab loj, tus nqi ntws loj thaum lub valve kev pab cuam lub neej luv. Lub valve tau kaw hom thiab hom zoo tib yam, rwb thaiv tsev thiab tsis yog rwb thaiv tsev.
5. Lub tshuab hluav taws xob npauj npaim valve tsuas yog muaj ob hom kev tswj, lub tshuab hluav taws xob yog tib yam li ntau nplooj valve.
