Daim ntawv thov uas tsis tshua muaj melting point alloy nyob rau hauv tsis siv neeg hluav taws kub hydrant thiab siab siab fusible valve

Tsis siv neeg hluav taws kub hydrants thiab high-pressure fusible li qub feem ntau siv eutectic low melting point alloys nrog lub melting point ntawm 68-72 degrees. Thaum qhov ntsuas kub ib puag ncig mus txog qhov melting point, cov fusible alloys yuav yaj thiab ntws tawm, thiab cov txheej txheem tswj yuav pib ua haujlwm. Cov hluav taws kub hydrants thiab fusible li qub yog siv los ua cov khoom siv tsis siv neeg Kev Nyab Xeeb xws li cov tsheb thauj dej haus, cov khoom siv tswb tsis siv neeg thiab lub qhov rooj hluav taws kub tsis siv neeg, thiab kev nyab xeeb li qub ntawm cov thawv ntim siab yog ua los ntawm cov hlau tsis muaj melting. Nrog rau kev hloov ntawm kev ua haujlwm, cov hlau tsis tshua muaj melting nrog cov ntsiab lus sib txawv tuaj yeem xaiv tau.
