Qhov zoo ntawm Hlau Ob Chav Bellows Expansion Joint:
Cov hlau ob lub tshuab txuas txuas txuas tuaj yeem nqus cov xaim xaim xaim xaim xaim xaim los ntawm lub kaum sab xis deflection ntawm cov yeeb nkab corrugated, uas muaj qhov zoo ntawm qhov muaj peev xwm loj thiab tsis muaj qhov siab sab hauv ntawm cov yeeb nkab ntev. Nws tsis tuaj yeem sib npaug ntawm qhov siab thrust ntawm cov yeeb nkab longitudinal. Cov pas nrig loj loj tuaj yeem siv rau ntawm L-shaped thiab Z-zoo li cov yeeb nkab seem. Hom corrugated compensator no tuaj yeem nqus cov kev hloov pauv mus rau sab nraud hauv ntau cov lus qhia los ntawm angular deflection, thiab muaj nyiaj ntau heev. Nws tsis muaj zog thiab thrust cuam tshuam rau kev txhawb nqa, thiab muaj cov qauv yooj yim. Nws yog dav siv nyob rau hauv ntau yam L-zoo li tus thiab Z-zoo li tus yeeb nkab seem nrog loj xaav. Noj tus pas loj rub pas nrig transverse corrugated compensator ua piv txwv, kab lus no piav qhia nws cov sijhawm thov. Cov yeeb nkab nruab nrab thiab cov yeeb nkab corrugated ntawm lub raj xa hluav taws xob tsuas yog dais lub voj voog ncig ntawm lub siab sab hauv, thiab tsis txhob dais lub axial quab yuam ntawm sab hauv siab, uas yog, axial quab yuam ntawm sab hauv siab txhim kho lub zog ntawm lub compensator. Thaum cov yeeb nkab kab rov tav hla dhau qhov kev hloov pauv vim qhov kub hloov pauv lossis lub zog sab hauv, cov qauv duab plaub uas muaj cov hlua rub loj tuaj yeem ua rau parallelogram deformation. Lub sij hawm no, cov corrugated hoses ntawm ob qho kawg ntawm lub compensator undergo opposite sab stretching thiab compression deformation, tso cai rau cov kab rov tav yeeb nkab seem txav mus dawb nyob rau hauv lub transverse kev taw qhia thiab nqus kev ntxhov siab.
