Vim li cas Bolt Charts tseem ceeb rau Butterfly Valves
Kev siv bolting yog lub hauv paus ntawm kev sib dhos valve kom ruaj khov. Qhov loj ntawm bolt, cov khoom siv, lossis torque tsis raug tuaj yeem ua rau muaj kev xau, valve tsis ua haujlwm, lossis txawm tias lub sijhawm tsis ua haujlwm ntawm lub system.daim ntawv qhia txog bolt rau flangeslos yog npauj npaim li qub ua tus qauv:
- Qhov ntev ntawm lub ntsia hlau(txoj kab uas hla, qhov ntev, hom xov).
- Kev sib xws ntawm cov khoom siv(cov hlau tsis xeb, cov hlau carbon).
- Cov nqi zogkom ua tiav qhov kev sib khi zoo tshaj plaws.

Kev Xaiv Khoom Siv Bolt: Stainless Steel vs. Carbon Steel
Stainless Hlau Npauj Npaim Valve Bolts
- Cov Qib:ASTM A193 B8 (304/316 SS) rau kev tiv taus corrosion siab.
- Cov ntawv thov:Kev lag luam tshuaj lom neeg, dej hiav txwv, lossis kev ua zaub mov.
- Lub zog tig:Qhov torque qis dua yuav tsum tau piv rau cov hlau carbon.
Cov Hlau Carbon Butterfly Valve Bolts
- Cov Qib:ASTM A307 lossis A325 rau lub zog tensile siab.
- Cov ntawv thov:Roj, roj av, thiab cov tshuab kub siab.
- Txheej:Galvanized los yog zinc-plated los tiv thaiv xeb.
