Dab tsi yog Expansion Joints siv rau?

Expansion pob qij txha (tseem hu ua expansion valves los yog compensators) yog cov cuab yeej tseem ceeb uas siv los nqus cov kev hloov pauv thiab kev ntxhov siab hauv cov kav dej uas tshwm sim los ntawm thermal expansion thiab contraction, vibration, lossis hauv av. Lawv tiv thaiv cov raj xa dej deformation thiab rupture, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.

Lawv feem ntau them nyiaj rau axial, lateral, thiab angular displacements hauv cov kav dej los ntawm lawv cov qauv elastic lossis zawv zawg. Lawv kuj nqus cov khoom vibration, txo cov suab nrov, thiab pab txhawb kev txhim kho thiab kho cov li qub thiab cov khoom siv.

Lawv feem ntau pom nyob rau hauv ntev -kab raj xa dej mus rau cov cua sov, roj, tshuaj, thiab fais fab kev lag luam.
