Flange gate valve yog lub rooj vag valve nrog flange kev twb kev txuas, txoj kev sib txuas no yog qhov feem ntau. Flange gate li qub yog ruaj khov thiab txhim khu kev qha thaum siv hauv cov kav dej, yog li flange gate li qub feem ntau siv hauv cov kav dej siab.
Thaum lub flange lub rooj vag valve raug kaw, lub sealing nto tsuas yog cia siab rau qhov nruab nrab siab rau kev sib khi, uas yog, cia siab rau qhov nruab nrab siab los nias lub sealing nto ntawm lub rooj vag mus rau lub rooj zaum ntawm lub rooj zaum ntawm sab nraud los xyuas kom meej lub sealing ntawm lub qhov rooj valve. lub sealing nto, uas yog tus kheej sealing. Feem ntau lub rooj vag valve siv yuam kev sealing, uas yog, thaum lub valve raug kaw, lub rooj vag yuav tsum raug quab yuam tawm tsam lub rooj zaum los ntawm kev quab yuam sab nraud los xyuas kom meej lub sealing nto.
Lub rooj vag ntawm lub rooj vag valve txav linearly nrog lub qia valve, uas yog hu ua lifting qia rooj vag valve (tseem hu ua lub nce qia rooj vag valve). Feem ntau muaj ib txoj hlua trapezoidal ntawm lub lifting pas nrig. Los ntawm cov txiv ntoo nyob rau sab saum toj ntawm lub valve thiab cov lus qhia zawj ntawm lub valve lub cev, cov lus tsa suab tau hloov mus rau cov lus tsa suab, uas yog, kev khiav hauj lwm torque yog tig mus rau hauv kev khiav hauj lwm thrust.
Thaum lub valve qhib, thaum lub qhov siab ntawm lub rooj vag yog sib npaug rau 1: 1 lub sij hawm lub valve txoj kab uas hla, cov kua dej yog kiag li unblocked, tab sis txoj hauj lwm no tsis tuaj yeem saib xyuas thaum lub sijhawm ua haujlwm. Hauv kev siv tiag tiag, lub apex ntawm lub qia valve yog siv los ua lub cim, uas yog, txoj haujlwm uas nws tsis tuaj yeem qhib, raws li nws txoj haujlwm qhib tag nrho. Txhawm rau coj mus rau hauv tus account qhov tshwm sim ntawm qhov ntsuas kub vim qhov hloov pauv, lub valve feem ntau yog qhib rau ntawm txoj hauj lwm apex thiab tom qab ntawd rov qab los ntawm 1/2 mus rau 1 tig raws li qhov qhib tag nrho valve. Yog li ntawd, lub siab qhib txoj hauj lwm ntawm lub valve yog txiav txim los ntawm txoj hauj lwm ntawm lub rooj vag (xws li mob stroke> .
Hauv qee lub rooj vag li qub, cov txiv ntoo qia yog teem rau ntawm lub rooj vag, thiab kev sib hloov ntawm lub tes log tsav kev sib hloov ntawm lub valve qia kom nqa lub rooj vag. Hom valve no yog hu ua rotating qia rooj vag valve los yog qia dub qia qhov rooj valve.
Installation ntawm flange rooj vag valve:
1. Tshawb xyuas sab hauv ntawm lub valve kab noj hniav thiab qhov chaw sealing ua ntej kev teeb tsa, thiab tsis muaj cov av lossis cov xuab zeb raug tso cai ua raws;
2. Lub bolts ntawm txhua qhov kev sib txuas yuav tsum tau nruj nruj;
3. Txheeb xyuas cov khoom ntim yuav tsum tau nias kom nruj, tsis yog tsuas yog ua kom nruj ntawm cov ntim khoom, tab sis kuj ua kom lub qhov rooj qhib tau yooj yim;
4. Ua ntej txhim kho lub valve, tus neeg siv yuav tsum xyuas cov qauv valve, kev sib txuas loj thiab ua tib zoo saib xyuas cov kev taw qhia ntws ntawm qhov nruab nrab kom ntseeg tau tias muaj kev sib haum xeeb nrog lub valve;
5. Thaum txhim kho lub valve, tus neeg siv yuav tsum tseg qhov chaw tsim nyog rau lub valve tsav;
6. Kev xaim ntawm cov cuab yeej tsav tsheb yuav tsum tau ua raws li daim duab thaiv;
7. Lub rooj vag valve yuav tsum tau khaws cia tsis tu ncua, thiab tsis muaj kev sib tsoo lossis nyem kom tsis txhob cuam tshuam rau lub foob.
Newsway Valves Materials
NSW valve lub cev thiab cov khoom siv trim tuaj yeem muab rau hauv Forged hom thiab Casting hom. Ntxiv rau cov khoom siv stainless thiab carbon steel, peb kuj tsim cov khoom siv tshwj xeeb xws li titanium, nickel alloys, HASTELLOY® *, INCOLOY®, MONEL®, Alloy 20, super-duplex, corrosion resistant alloys thiab urea qib cov ntaub ntawv.
