GB Hard thiab Mos Sealing Floating Ball Valves Txheej txheem cej luam: Kev ua tau zoo, kev siv, thiab cov qauv
Lub teb chaws tus qauv mos thiab tawv kaw ntab ntab pob valve yog lub valve siv los tswj cov kua dej, uas muaj kev sib khi zoo thiab cov kua dej me me. Hauv tsab xov xwm no, peb yuav qhia txog cov yam ntxwv, kev siv, thiab kev ua haujlwm tseem ceeb ntawm lub teb chaws tus qauv muag muag thiab nyuaj kaw ntab pob li qub.
1. Khoom nta
Lub teb chaws tus qauv mos thiab tawv kaw lub pob valve muaj cov yam ntxwv hauv qab no:
-Low fluid resistance: Pob li qub muaj cov kua dej qis tshaj plaws ntawm txhua hom valve, txawm tias txo txoj kab uas hla pob li qub, lawv cov dej tsis kam yog me me.
- Ceev thiab yooj yim qhib thiab kaw: ntev li ntev raws li lub valve qia tig 90 °, lub pob valve yuav ua tiav qhov qhib tag nrho lossis kaw tag nrho, ua kom yooj yim kom ua tiav sai thiab kaw.
-Kev ua tau zoo sealing: Lub rooj zaum pob valve raug kaw, nrog kev sib khi zoo.
2. Khoom siv
Lub teb chaws tus qauv mos thiab tawv kaw lub pob valve yog tsim rau cov roj av, nkev, tshuaj, tshuaj, khoom noj, hluav taws xob, dej, metallurgy, thiab kev lag luam. Flange floating pob valve yog ib txoj kev sib txuas, haum rau ntau yam kev ua haujlwm.
3. Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm
Nominal siab (MPa): Lub nominal siab ntau yam ntawm lub teb chaws tus qauv mos mos thiab nyuaj kaw floating pob valve yog 0.6 ~ 42.0 MPa, thiab cov qib siab tsim nyog xaiv tau raws li kev ua haujlwm sib txawv.
Qhov ntsuas kub: Qhov ntsuas kub siv tau rau cov qauv zoo tib yam lub teb chaws tus qauv mos thiab tawv kaw ntab pob li qub yog -196 ℃ ~ 550 ℃, thaum leej faj tiv thaiv lub teb chaws tus qauv mos thiab tawv kaw ntab pob li qub yog tsim rau cov roj av, roj av thiab lwm yam xov xwm uas muaj H2S thiab CO2.
Siv tau xov xwm: National standard soft and hard sealed floating ball valves are suited for media such as water, steam, petroleum, liquefied gas, and natural gas.
4. Cov khoom siv tseem ceeb
Cov ntaub ntawv tseem ceeb ntawm lub teb chaws tus qauv muag muag thiab tawv kaw lub pob valve muaj xws li carbon steel series, stainless hlau series, sulfur resistant series, thiab low-temperature steel series. Cov ntaub ntawv no tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm sib txawv, ua kom lub zog thiab kev ntseeg siab ntawm lub valve.
5. Cov qauv kev ua haujlwm
Lub teb chaws tus qauv mos thiab tawv kaw lub pob valve yog tsim thiab tsim raws li cov qauv xws li GB / T12237, GB / T12221, GB / T12224, thiab GB / T12220. Cov qauv no qhia txog qhov yuav tsum tau ua rau qhov ntev ntawm cov qauv, txuas flanges, kuaj thiab tshuaj xyuas li qub, ua kom ntseeg tau cov khoom zoo.
Hauv cov ntsiab lus, lub teb chaws tus qauv muag muag thiab tawv kaw ntab pob valve yog lub valve nrog kev ua haujlwm zoo, siv dav hauv ntau yam kev lag luam. Kev nkag siab txog nws cov yam ntxwv, kev siv, thiab kev ua haujlwm tseem ceeb tuaj yeem pab peb xaiv thiab siv hom valve no zoo dua.
