Dab tsi yog Bellow Valve

Dab tsi yog lub Bellow Valve

A lub valve qhib, tseem hu ua lub bellows seal valve, yog ib hom valve kev lag luam tsim los tiv thaiv kom tsis txhob muaj kua dej xau rau sab nraud. Nws siv lub bellows hlau ua lub dynamic seal element ntawm lub valve stem thiab lub cev, hloov txoj kev ntim khoom ib txwm muaj. Qhov kev tsim no zoo tshwj xeeb hauv cov kab ke ua kua tshuaj lom, txaus ntshai, hluav taws kub, lossis cov kua dej huv siab uas yuav tsum txo qis lossis tshem tawm cov kua dej xau.

Yuav ua li cas lub Bellow Valve ua haujlwm

Cov hlau bellows hauv lub valve nthuav dav thiab luv thaum lub valve stem txav mus los, tsim ib lub foob hermetic uas cais cov kua hauv lub valve ntawm huab cua. Cov bellows raug welded rau ob qho tib si lub valve stem thiab lub bonnet, kom ntseeg tau tias tsis muaj qhov xau thaum lub sijhawm ua haujlwm. Ib lub foob ntim khoom thib ob feem ntau ntxiv rau kev nyab xeeb ob npaug.

Qhov twg yog Bellow Valves siv

Bellow valves siv dav hauv kev lag luam uas qhov kev ua haujlwm tsis muaj qhov xau yog qhov tseem ceeb:

• ① Kev tsim kho dej hiav txwv thiab nkoj (piv txwv li, roj roj thiab cov txheej txheem tshuaj lom neeg)

• ②Petrochemical thiab tshuaj ua tiav

• ③Tshuaj

• ④Cov chaw tsim hluav taws xob nuclear thiab fais fab

• ⑤Kev tsim khoom siv semiconductor

• ⑥Cryogenic thiab high-vacuum systems

Cov txiaj ntsig ntawm Bellow Valves

• ①Zero qia to, zoo tagnrho rau cov xov xwm txaus ntshai lossis flammable

• ② Lub neej ntev vim yog lub bellows uas yoog tau tab sis ruaj khov

• ③Ob chav kaw lus (bellows + packing)

• ④Kev nyab xeeb ua haujlwm siab thiab kev tiv thaiv ib puag ncig

• ⑤ Ua tau raws li cov qauv kev lag luam nruj rau kev tswj emission (piv txwv li ISO 15848, TA-Luft)

Cov Nta Tseem Ceeb

• ① Khoom siv: Hlau tsis xeb, hlau carbon, lossis hlau alloy

• ②Qhov kawg txuas: Flanged, threaded, lossis welded

• ③Bellows: Cov hlau tsis xeb ntau txheej rau kev ywj pheej thiab kev ua haujlwm ntev

• ④Kev Ua Haujlwm: Tes log tes lossis lub tshuab ua haujlwm

• ⑤Cov hom tsim: Globe valve style (feem ntau), lub kaum sab xis lossis Y-qauv
