Qhov Nruab Nrab Xaiv

1. Li qub rau kaw thiab qhib xov xwm

Qhov chaw txaus yog qhov ncaj-los ntawm valve, uas nws tau ntws tawm yog me me, thiab lub valve feem ntau raug xaiv raws li kev txiav thiab qhib nruab nrab. Downward kaw li qub Nyob rau hauv cov ntaub ntawv uas siab txaus tsis kam yog tso cai, kaw li qub tuaj yeem xaiv.

2. Valve rau kev tswj hwm ntws

Feem ntau xaiv lub pob valve uas yooj yim los kho tus nqi txaus raws li kev tswj hwm ntws. Downward kaw li qub, xws li zoo li lub ntiaj teb li qub, yog qhov haum rau lub hom phiaj no vim lawv lub rooj loj yog sib npaug ntawm cov neeg mob stroke. Teb li cas (plug li qub, npauj kheej li qub, pob li qub) thiab siv li cas rau kev tswj hwm throlle) Rooj vag valve yog lub rooj vag disc zoo li cas rau txoj kev sib tw sib tw, nws tsuas yog kaw qhov chaw uas kaw, yog li nws feem ntau tsis yog siv rau kev tswj hwm ntws.

3. Reversing Shunt Valve

Lub valve yuav muaj peb lossis ntau dua channel, nyob ntawm qhov kev xav tau rau reversing shunt. Plug thiab lub pob li siab dua rau lub hom phiaj no, yog li cov li qub siv rau reversing shunt siv ib qho ntawm cov li qub. Txawm li cas los xij, qee kis, lwm hom li qub, ntev li ntev tau ob lossis ntau npaum li cas li ob lossis ntau npaum li cas li qub yog txuas nrog txhua lwm yam, kuj tseem siv tau rau thim shunt.

4. Li qub rau nruab nrab nrog kev ncua cov lus

Thaum muaj cov neeg raug tshem tawm nyob rau hauv nruab nrab, nws yog qhov zoo tshaj plaws los siv lub zawv zawg valve nrog cov khoom so raws cov chaw sib khi. Yog tias qhov kaw yog ntsug nyob rau hauv nws cov sab nraud thiab tawm suab tawm tsam lub rooj zaum, yog li lub valve tsuas yog tsim nyog sib khi cov khoom saum npoo av tso cai rau embedding ntawm hais. Pob li qub thiab ntsaws li qub muaj cov txiaj ntsig wiping rau ntawm kev sib khi saum npoo thaum qhib thiab kaw, yog li lawv haum hauv xov xwm nrog ncua cov nplais.
