Kev faib tawm thiab cov yam ntxwv ntawm Fixed Ball Valves

Pob li qub tau muab faib ua: pob li qub, pob li qub, pob li qub, orbital pob li qub, V-hom pob li qub, peb-txoj kev pob li qub, stainless hlau pob li qub, forged steel pob li qub, cov hmoov tshauv tawm pob li qub, sulfur-resistant pob li qub. , peb-txoj kev pob li qub, pneumatic pob li qub, hluav taws xob pob li qub, ferrule pob li qub, thiab welded pob li qub.
Raws li kev faib tawm ntawm cov khoom siv hauv tsev / lub cev, pob li qub tuaj yeem muab faib ua:
1. Cov khoom siv hlau: xws li carbon steel li qub, alloy steel li qub, stainless hlau li qub, cam khwb cia hlau li qub, titanium alloy li qub, Monel li qub, tooj liab alloy li qub, aluminium alloy li qub, txhuas alloy li qub, thiab lwm yam.
2. Hlau lub cev hauv ob sab phlu li qub: xws li roj hmab hauv ob sab phlu li qub, fluorine hauv ob sab phlu li qub, txhuas hauv ob sab phlu li qub, yas hauv ob sab phlu li qub, enamel lining li qub.
3. Cov khoom siv tsis yog xim hlau: xws li ceramic li qub, iav li qub, yas li qub.
Raws li txoj kev sib txuas, nws tuaj yeem muab faib ua: threaded pob valve, flanged pob valve thiab phaj pob valve.
Muaj ntau lub tuam txhab ntawm pob li qub nyob hauv Suav teb, thiab feem ntau ntawm qhov sib txuas qhov ntau thiab tsawg tsis sib xws.
GB/T 12221-2005 "Metal Valve Structure Length" yog chav kawm dav dav.
Feem ntau ntawm domestic pob valve manufacturers yog tsim thiab tsim raws li tus qauv no. Txawm li cas los xij, tus qauv no tsis zoo tag nrho, cov lus qhia tshwj xeeb tsis tiav, qhov siab tshaj plaws nominal txoj kab uas hla ntawm lub pob valve yog DN1200, thiab qhov siab tshaj plaws nominal txoj kab uas hla ntawm lub pob valve yog DN2000. Raws li cov lus qhia tshwj xeeb ntawm lub valve tsim los ntawm lub Hoobkas thiab cov ntaub ntawv muaj, qhov tsawg kawg nkaus nominal txoj kab uas hla ntawm lub pob valve yog DN6, thiab qhov tsawg kawg nkaus nominal txoj kab uas hla ntawm lub pob valve yog DN50. Txhawm rau kom muaj cov qauv sib koom ua ke, tib qhov kev qhia tshwj xeeb tuaj yeem hloov pauv tau thaum tus neeg siv xaiv thiab nruab, thiab nws tau pom zoo kom National General Machinery Research Institute tau kho GB/T 12221-2005 "Hlau Valve Structure Length". Nws raug pom zoo tias lub koom haum tsim thiab cov neeg siv xaiv raws li tus qauv, thiab cov chaw tsim khoom pob valve yuav tsum tsim thiab tsim khoom raws li tus qauv.
