Bellows ntiaj teb li qub, tseem hu ua bellows kaw lub ntiaj teb li qub, yog tsim los tsim cov hlau thaiv nruab nrab ntawm cov kua nruab nrab thiab cov cua los ntawm kev siv lub tshuab hob-welding kom paub tseeb tias xoom qia to. Piv nrog rau lub ntiaj teb niaj hnub valve muaj cov hauv qab no zoo:
1. Bellows ntiaj teb valve ntev kev pab cuam lub neej, txo tus naj npawb ntawm cov txij nkawm, txo cov nqi khiav lag luam. Rugged bellows foob tsim ua kom xoom qia to thiab muab kev saib xyuas tsis pub muaj xwm txheej.
2. Valve qhib thiab kaw torque yog me me, txo kev siv zog, thiab tuaj yeem tsav txhua hom kev tsav tsheb, yooj yim rau kev tswj chaw taws teeb.
3. Zoo nkauj tsos, lub valve channel muaj ib tug du khiav kab, txo cov ndlwg tsis kam coefficient ntawm lub valve, yog ib yam ntawm cov khoom zoo zog-txuag.
4. Lub foob sab nrauv ntawm lub valve siv lub foob foob thiab graphite, stainless hlau gasket foob, kev ruaj ntseg foob, kev siv mus sij hawm ntev tsis tuaj yeem hloov cov sealing packing. Hauv kev siv hauv kev lag luam, qhov zoo tib yam nres valve tshwm sim los ntawm kev xau: kub siab, muaj kuab lom heev, nplaim taws thiab tawg, xov tooj cua thiab lwm yam, tsis yog tsuas yog muaj kuab paug ntawm ib puag ncig, tab sis kuj feem ntau ua rau tus kheej thiab cov khoom poob. Lub hauv paus nres valve muaj kev nyab xeeb dua thiab ruaj khov, thiab cov txheej txheem thoob ntiaj teb tau nruj me ntsis rau hauv kev tsim thiab tsim khoom.
Qhov zoo thiab kev siv ntawm bellows ntiaj teb valve
Bellows nres valve tsis muaj to, siv nyob rau hauv high-risk media yog kuj muaj kev nyab xeeb.
Ordinary globe li qub yog kaw nrog cov ntim, nruab nrab ntawm cov qia thiab cov ntim yuav swb, yooj yim kom xau ntawm qhov kub thiab txias (spool).
Bellows lub ntiaj teb valve tuaj yeem ncav cuag thiab compressed foob es tsis txhob ntim cov foob, tuaj yeem tiv thaiv cov khoom poob los ntawm kev tawm sab nraud. Feem ntau yog siv rau kev sib kis ntawm qhov nruab nrab muaj zog permeable, xws li lub valve ntawm hydrogen system, tsuav yog lub hauv paus tsis puas, feem ntau tsis muaj qhov to; Thiab lub ntiaj teb dav dav valve nrog ntim rau ntim, yooj yim rau xau.
Hom valve qia qhib lossis kaw stroke yog luv luv, thiab muaj kev txhim khu kev qha zoo heev, thiab vim tias qhov kev hloov ntawm lub rooj zaum valve los ntawm cov hlab ntsha ntawm lub disc yog ncaj qha proportional rau kev sib raug zoo, haum rau kev khiav dej num. Yog li ntawd, hom valve no zoo haum rau kev txiav los yog tswj thiab throttling siv.
