Q: Kodi ma valavu a boiler and amagwira bwanji ntchito ndi chiyani?

Yankho: Valve ya chitetezo ndi gawo lofunikira chitetezo mu boiler. Ntchito yake ndi: Kupanikizika kwa Steam Boiler ndi yayikulu kuposa mtengo womwe wafotokozedwa (mwachitsanzo, valavu ya chitetezo) imangotsegula valavu kuti itulutse mpumulo; Kupanikizika kwa boiler kumatsikira kwa mtengo wofunikira (mwachitsanzo), valavu yotetezedwa imangotseka yokha, kuti boiler itha kugwiritsidwa ntchito nthawi yayitali. Kwa nthawi yayitali, pewani kuphulika komwe kumachitika chifukwa cha kuchuluka kwa boiler.
Cholinga chokhazikitsa ndi kusintha valavu yoteteza kuti musunge kukakamizidwa ndikukumbutsani zowonera pomwe boiler ikadzaza chifukwa chogwiritsa ntchito bwino. Ena mwa ma boiler ena alibe zida zokhala ndi valavu ya mpweya. Madzi akalowa mu ng'anjo yozizira kuti akweze moto, valavu yoteteza ikuchotsabe mpweya mu thupi la ng'anjo; Imachoka.

Valavu ya chitetezo imakhala ndi mpando wa valavu, valavu yolumikizana ndi chipangizo cholimbikitsira. Vesi lomwe lili mu valavu yoteteza imalumikizana ndi malo opukutira a boiler, ndipo valavu ya valavu imapanikizika mwamphamvu pampando wa valavu yopangidwa ndi chipangizo cholimbikitsira. Pamene mphamvu yokakamiza yomwe Valve imatha kupirira ndi yayikulu kuposa momwe imakhalira ndi nthunzi pachilavu, valavu yopanda m'manja, ndipo valavu ya chitetezo ili pamalo otsekeka; Kupanikizika kwa nthunzi mu boiler kumatuluka, mphamvu ya Steam yomwe ikugwira ntchito pachimake, pomwe mphamvu yake ndiyokulirapo, valavu ya chitetezo idzatseka, ndipo boiler idzatsegulidwa nthawi yomweyo.
Chifukwa chakutulutsa kwa nthunzi mu boiler, kukhazikika kwa nthunzi mu boiler kumachepetsedwa, ndipo kukhazikika kwa nthunzi kuti valavu yophatikizika idzachepetsedwa, ndipo valavu imatsekedwa.
Boiilers wokhala ndi zopota zochulukirapo kuposa 0,5t / h kapena kuvotera mphamvu yayikulu kuposa kapena 350kw kukhala ndi ma valve awiri otetezeka; Boilers omwe ali ndi zotupa zosakwana 0,5t / h kapena kuvotera mphamvu zosakwana 350kW kudzakhala ndi valavu imodzi yotetezeka. Mavesi ndi Mavalli otetezedwa ayenera kukondweretsedwa pafupipafupi ndipo azisindikizidwa pambuyo poyambira.
