Kos lub valve yog tso siab rau qhov ntws ntawm qhov nruab nrab nws tus kheej thiab qhib thiab kaw lub valve disc, siv los tiv thaiv cov xov xwm ntws rov qab valve, tseem hu ua check valve, ib-txoj kev valve, countercurrent valve, thiab rov qab siab valve.
Txheeb xyuas qhov kev ua haujlwm valve
Kos valve yog hom tsis siv neeg valve, nws lub luag haujlwm tseem ceeb yog los tiv thaiv kev tshaj tawm rov qab, tiv thaiv lub twj tso kua mis thiab tsav lub cev muaj zog rov qab, nrog rau kev tso tawm ntawm lub thawv nruab nrab.Kos li qub kuj tseem siv tau los muab cov kab uas lub siab tuaj yeem nce siab tshaj qhov system siab hauv lub koom haum pabcuam.
Classification ntawm check valves
Kos li qub tuaj yeem muab faib raws li lawv cov qauv thiab kev teeb tsa:
1. Viav kos valve
Lub viav vias kos valve disc disc, tig ib ncig ntawm lub rooj zaum lub rooj zaum channel axis rau kev txav txav, vim tias lub valve channel mus rau hauv cov kab khiav, ntws tsis kam yog me me dua li lub lifting check valve, haum rau qis qis tshaj tawm thiab tsis tshua muaj kev hloov pauv ntawm txoj kab uas hla loj. , tab sis tsis yog rau pulsating txaus, nws sealing kev ua tau zoo tsis zoo li lifting.Lub viav vias kos valve tau muab faib ua ib qho, ob npaug thiab ib nrab peb hom, peb hom no feem ntau yog muab faib raws li lub valve txoj kab uas hla, lub hom phiaj yog los tiv thaiv qhov nruab nrab kom tsis txhob ntws los yog thim rov qab, ua rau muaj kev cuam tshuam hydraulic.
2. Nqa daim tshev valve
Disc raws txoj kab nruab nrab ntawm lub valve lub cev swb kos valve, nqa daim tshev valve tuaj yeem ntsia tau rau hauv kab rov tav, nyob rau hauv qhov siab siab me me kab kos valve disc tuaj yeem siv rau hauv pob.Nqa daim tshev valve lub cev thiab lub ntiaj teb valve (tuaj yeem siv nrog lub ntiaj teb valve), yog li nws cov dej tsis kam coefficient loj dua.Cov qauv zoo ib yam li lub ntiaj teb valve, thiab lub valve lub cev thiab disc yog tib yam li lub ntiaj teb valve.Lub sab sauv ntawm lub valve disc thiab sab qis ntawm lub valve npog yog ua tiav nrog lub tes tsho qhia, lub valve disc qhia ntawv tuaj yeem ua kom tsis txhob sawv thiab poob rau hauv daim ntawv qhia lub teeb valve, thaum nruab nrab qis qis, lub valve disc los ntawm qhov nruab nrab thrust qhib, thaum nruab nrab nres ntws, lub valve disc los ntawm ntsug tsaws ntawm lub rooj zaum, tiv thaiv qhov nruab nrab countercurrent nyhuv.Ncaj-los ntawm lifting kos valve nruab nrab inlet thiab qhov hluav taws xob channel kev taw qhia thiab valve rooj channel kev taw qhia ntsug;Vertical lift check valve, nws nruab nrab inlet thiab qhov hluav taws xob channel kev taw qhia thiab lub rooj channel kev taw qhia yog tib yam, qhov ntws tsis kam yog me dua ncaj nraim.
3. Disc kos valve
Ib daim tshev valve uas lub disc tig ib ncig ntawm tus pin hauv lub rooj zaum.Disc kos valve qauv yog yooj yim, tsuas yog ntsia tau rau hauv kab rov tav raj, tsis zoo sealing.
4. Cov yeeb nkab kos valve
Valve qhov twg lub disc swb raws qhov nruab nrab ntawm lub cev.Cov yeeb nkab kos valve yog lub valve tshiab, nws qhov ntim me me, lub teeb yuag, kev siv tshuab zoo, yog ib qho kev txhim kho ntawm kev kos valve.Tab sis cov kua kuj coefficient yog me ntsis loj dua lub viav vias kos li qub.
5. Siab check valve
Lub valve no yog siv rau boiler pub dej thiab chav txiav tawm valve, nws muaj lifting check valve thiab ntiaj teb valve los yog lub kaum sab xis valve kev ua haujlwm.
Nortech yog ib qho ntawm cov ua lag luam valve manufacturers hauv Suav teb nrog cov ntawv pov thawj zoo ISO9001.
