Carbon steel riam rooj vag valve yog hauv qab ntawm lub tiaj tiaj tiaj valve phaj nrog riam-hom beveled txiav, nrog rau kev ua haujlwm ntawm kev txiav tawm qhov nruab nrab, kom lub valve kaw tsis thaiv qhov nruab nrab. Lub valve no feem ntau yog siv rau cov ntaub so ntswg, thee tshauv, tshuaj raw khoom, dej phwj tuaj, zaub mov thiab lwm yam xov xwm ncig qhib thiab kaw. Kev kub siab feem ntau yog siv nyob rau hauv 1.6MPa, qhov kub thiab txias feem ntau siv qis dua 120 degree, kub kub kuj tseem siv tau los hloov cov ntaub ntawv tshwj xeeb.

Carbon Riam rooj vag Valve
Carbon steel riam rooj vag valve sealing cov lus qhia
1. Mos sealing (ib-txoj kev los yog ob-txoj kev) kub tsawg dua los yog sib npaug rau 280C: muaj feem xyuam rau cov pa roj, kua thiab lwm yam fluidity, tsawg ntom gas-kua media. Qhov zoo: muaj zog sealing kev ua tau zoo, tsis yooj yim rau xau sab hauv thiab sab nraud. Qhov tsis zoo: kev sib cuag nrog cov khoom lossis cov xov xwm kub siab yuav ua rau muaj kev puas tsuaj.
2. Hard seal (ib-txoj kev los yog ob-txoj kev) Qhov kub thiab txias tsawg dua los yog sib npaug rau 1000C: rau ntau yam khoom, plua plav, cov khoom thiab lwm yam khoom nyuaj. Advantage: muaj zog abrasion tsis kam. Disadvantages: tsis zoo sealing, tsis siv rau lwm yam thiab kua thiab lwm yam kav dej.
Kev txhim kho thiab siv riam rooj vag valve
1. Ua ntej kev teeb tsa, lub valve kab noj hniav thiab qhov chaw sib khi yuav tsum tau kuaj xyuas, thiab tsis muaj av lossis xuab zeb raug tso cai ua raws;
2. Lub bolts ntawm txhua qhov kev sib txuas yuav tsum tau muab nruj kom sib npaug. 3;
3. xyuas cov khoom ntim yuav tsum tau siab, tsis tsuas yog xyuas kom lub sealing ntawm lub ntim, tab sis kuj yuav xyuas kom meej tias lub qhov rooj qhib flexibly;
4. Ua ntej txhim kho lub valve, tus neeg siv yuav tsum tau ua pov thawj ntawm lub valve qauv, kev sib txuas loj thiab kev saib xyuas rau qhov nruab nrab ntws cov kev taw qhia, kom ntseeg tau tias sib xws nrog lub valve yuav tsum tau;
5. cov neeg siv nyob rau hauv lub installation ntawm lub valve, yuav tsum tseg qhov chaw tsim nyog rau lub valve tsav;
6. tsav thaiv yuav tsum tau ua raws li daim duab kos;
7. riam rooj vag valve yuav tsum tsis tu ncua, tsis txhob sib tsoo thiab extrusion, thiaj li tsis cuam tshuam rau lub foob.
