Dab tsi yog Qhov Loj thiab Hom?

Rising vs. Non-Rising Stem

Qhov txawv ntawm tus qauv

Stainless hlau rooj vag li qub tau muab faib ua sab nraud ntsia hlau & yoke (OS & Y) nce qia thiab sab hauv ntsia hlau tsis-nce qia ob qhov tsim.

Rising Stem: Lub qia valve txav nce thiab nqis, thiab cov qia threads raug tawm sab nraum lub valve lub cev.

Handwheel rotation → qia extends upward → wedge gate nces qhib lub valve.

Non-Rising Stem: Lub qia tsuas tig tsis tau nqa. Tag nrho cov qia threads yog nyob rau hauv lub valve lub cev thiab muab tso rau hauv nruab nrab.

Handwheel rotation → internal threads tsav lub rooj vag nce thiab nqis, thaum lub qia qhov siab tseem tsis hloov.

Visual & Open Indication

Rising Stem: Lub qia txuas ntev dua, qhib lub valve ntau dua.

Cov xwm txheej qhib / kaw tuaj yeem pom ncaj qha nrog lub qhov muag liab qab, pom meej ntawm qhov tsis muaj qhov ntsuas.

Non-Rising Stem: Lub qia qhov siab nyob twj ywm txhua lub sijhawm.

Qhov qhib degree tsis tuaj yeem pom ncaj qha; lub valve xwm yeem tsuas yog txiav txim los ntawm cov nplais ntawm tes lossis cov ntsuas.

Qhov yuav tsum tau muaj rau installation

Rising Stem: Lub qia txuas mus rau sab saud thaum qhib, xav tau qhov chaw ntsug loj saum lub valve.

Tsis haum rau lub qab nthab lossis cov kav dej nqaim.

Non-Rising Stem: Lub qia tsis sawv, nyob qhov chaw tsawg kawg nkaus. Haum rau thaj chaw qis qis, qhov dej hauv av, trenches thiab cov kav dej faus.

Corrosion Resistance & Kev Pabcuam Lub Neej

Rising Stem: Cov qia xov uas muaj qhov tsis zoo rau cov dej noo, plua plav, corrosion thiab xeb.Short service life in the outdoor, humid and acid-base environments.

Non-Rising Stem: Internal threads tiv thaiv los ntawm nruab nrab thiab cais tawm ntawm huab cua thiab dej nag.Zoo tiv thaiv corrosion kev ua tau zoo thiab kev pab lub neej ntev dua.

Media Compatibility

Rising Stem: Haum rau txhua yam kev tshaj tawm, nrog rau cov dej phwj tuaj, impurities thiab hais.

Non-Rising Stem: Internal threads ua rau impurity thaiv, clogging thiab seizing.Tsis haum rau cov dej phwj tuaj, slurry thiab qias neeg; tsuas yog siv tau rau cov dej huv, cov khoom siv roj huv thiab cov roj huv huv.

Kev Saib Xyuas & Kev Tshuaj Xyuas

Rising Stem ： Cov kab uas raug kab mob tuaj yeem ua rau xeb thiab xav tau lubrication tsis tu ncua.Stem jamming thiab abrasion yog qhov pom kev pom, ua rau kev saib xyuas thiab tshuaj xyuas yooj yim.

Non-Rising Stem Gate Valve: Internal malfunctions tsis tuaj yeem pom sab nraud. qia hnav thiab ntes yog ib qho nyuaj rau kev kuaj xyuas thiab kho, yog li lub valve feem ntau hloov tag nrho ib zaug puas lawm.

Siab & Loj Ntau

Rising Stem: Muaj nyob rau hauv ntau yam me me, nruab nrab thiab loj diameters.

Non-Rising Stem: Feem ntau yog tsim nyob rau hauv nruab nrab thiab loj diameters, dav siv rau underground faus pipelines.

Feem ntau, ob hom Stainless Steel Gate Valves tau siv dav hauv kev siv txhua hnub. Koj tuaj yeem xaiv cov khoom tsim nyog raws li kev ua haujlwm sib txawv.
