Thaum xub thawj, tib neeg siv tsiaj nkaum sewn ua ke los tsim cov qauv tubular kom tau raws li qhov xav tau ntawm kev tsim khoom thiab kev sib ntaus sib tua. Tom qab lub sijhawm tseem ceeb, los ntawm lub xyoo pua 17th, Vandel Geigen cov kwv tij ntawm Netherlands tsim longitudinally sewn canvas hoses, uas tau siv dav hauv kev tua hluav taws thaum lub sijhawm. Tom qab ntawd, nrog kev tshwm sim ntawm cov roj hmab hauv kev lag luam thoob ntiaj teb thiab kev tsim cov tshuab vulcanization, roj hmab hoses thiab roj hmab hoses armored nrog hlau hlau los yog hemp hlua tau qhia. Txawm li cas los xij, rau cov ntawv thov engineering uas suav nrog siab -kub xov xwm xws li chav dej thiab cua kub, qis-kub xov xwm xws li kua hydrogen, kua oxygen, thiab kua helium, nrog rau cov xov xwm corrosive xws li roj av, kerosene, acids, thiab alkalis, cov roj hmab hoses tsis tsim nyog. Tshwj xeeb tshaj yog nyob rau hauv siab - qhov kub thiab txias, lawv txoj kev nyab xeeb thiab kev ntseeg tau yog qhov nyuaj rau lav.
Yog li ntawd, tib neeg maj mam tsom lawv cov xim rau cov kav hlau, hloov kho lawv cov geometry los tsim cov corrugations sib xws ntawm lawv qhov chaw sab hauv thiab sab nrauv. Qhov no ua rau lawv yooj yim ntawm cov roj hmab hoses thaum tseem muab kev tiv thaiv rau siab thiab qis kub, kev laus, thiab corrosion. Yog li, cov hlau corrugated hose, raws li lub cev ntawm cov hlau saj zawg zog hose, tau yug los.
Nyob rau hauv 1855, lub teb chaws Yelemees thawj zaug luam tawm patent rau kev tsim cov tshuab raj. Nws siv cov ntsiab cai uas twb muaj lawm ntawm kev tsim cov hniav nyiaj hniav kub los tsim cov hauv qab. Peb caug xyoo tom qab ntawd, E. Levavasseur ntawm Fabkis thiab H. Witzenmann ntawm lub teb chaws Yelemees koom tes los tsim ib hom tshiab ntawm cov hlau bellows, tau txais patents nyob rau hauv Fabkis thiab lub teb chaws Yelemees thaum lub yim hli ntuj 1885.
Qhov no yog ib qho kauv bellows ua los ntawm winding S-zoo li tus hlau strips ntawm cov cuab yeej tshwj xeeb. Cov roj hmab strips, paj rwb ntaub, los yog asbestos hlua tau siv los sau cov seams ntawm qhov chaw uas nyob ib sab los pab txhawb lub foob nyob rau hauv lub plab kab noj hniav.
Nyob rau hauv 1894, cov qauv ntawm no hom bellows tau txhim kho: ob hlau strips ntawm txawv diameters raug mob nyob rau hauv opposite lus qhia. Qhov no tso cai rau cov hlau strips kom ua tiav qhov sib npaug ntawm kev ntxhov siab, kov yeej qhov teeb meem ntawm tus kheej -unwinding.
Hauv xyoo 1929, lwm qhov kev hloov kho thev naus laus zis tau tshwm sim hauv cov qauv ntawm lub tshuab raj, daws qhov teeb meem ntawm qhov poob ntawm kev sib khi ua haujlwm los ntawm kev hloov pauv tsis sib xws hauv cov grooves ntawm cov roj hmab strips lossis asbestos ropes siv rau kev sau thaum khoov. Qhov no tau qhib qhov kev cia siab dav rau txoj kev loj hlob ntawm cov kab. Integral bellows yog tsim los ntawm steel thiab tooj liab-zinc alloys, siv seamless los yog welded yeeb nkab cov ntaub ntawv. Cov bellows cia siab rau qhov elastic deformation ntawm corrugated sidewalls kom tswj tau ib qho kev sib tw ntawm compressibility lossis stretchability thaum ua kom muaj kev ruaj ntseg foob.
Txij xyoo 1950 mus, ob - txheej, triple - txheej, thiab ntau- txheej tshuab, tshwj xeeb tshaj yog ultra- nyias- cov phab ntsa stainless hlau bellows, tsim sai heev. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua, ntau yam txheej txheem xws li vuam, electroforming, machining, hydraulics, thiab mechanical spinning tau siv los tsim cov tshuab raj. Qhov tsawg kawg nkaus nominal txoj kab uas hla yog 2 hli, thiab qhov siab tshaj plaws nominal txoj kab uas hla tuaj yeem ncav cuag 400-500 hli, nrog rau cov kab loj loj mus txog 10 meters hauv txoj kab uas hla. Tus naj npawb ntawm corrugations txawv ntawm qhov tsawg kawg yog 1-2 mus rau pua pua, txhiab, lossis txawm kaum txhiab.
Los ntawm qhov kev xav ntawm cov yeeb nkab corrugated qhov tseem ceeb raws li lub cev ntawm cov hlau hloov tau yooj yim, kev loj hlob ntawm cov kav hlau corrugated qhia txog kev txhim kho ntawm cov hlau hloov tau yooj yim.
Tom qab ntawd, cov ntaub ntawv xws li roj hmab, yas, los yog nylon tau coated mus rau lub corrugated yeeb nkab sab nrauv, thiab ib tug braided sheath muaj li ntawm hlau nyob ntawm tej los yog strips, uas ua rau muaj ntau yam sib koom ua ke. Qhov no tau coj mus rau kev tsim ntau hom kev hloov pauv hlau hoses kom ua tau raws li cov kev cai sib txawv ntawm ntau yam kev siv.
