1. Valavu yochepetsera kupanikizika ndi valavu yomwe imachepetsa kuthamanga kwa mpweya wolowera kumalo enaake ofunikira kudzera mukusintha, ndipo imadalira mphamvu ya sing'angayo yokha kuti ikhale yokhazikika.Kuchokera pamawonedwe a makina amadzimadzi, valavu yochepetsera mphamvu ndi chinthu chogwedeza chomwe kukana kwake kungasinthidwe, ndiko kuti, kusintha malo otsekemera, kuthamanga kwa kuthamanga ndi mphamvu ya kinetic ya madzimadzi amasinthidwa, zomwe zimapangitsa kuti pakhale kupanikizika kosiyana. zotayika, kuti akwaniritse cholinga cha decompression.Ndiye kudalira kusintha kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake
2. Valavu yotetezera ndi gawo lotsegula ndi lotseka lomwe limakhala lotsekedwa kawirikawiri pansi pa mphamvu ya kunja.Pamene kupanikizika kwapakatikati pazida kapena payipi kumakwera pamwamba pa mtengo wotchulidwa, zidzateteza kupanikizika kwapakatikati mu payipi kapena zipangizo kuti zisapitirire mtengo wotchulidwa mwa kutulutsa sing'anga kupita kunja kwa dongosolo.ma valve apadera.Ma valve otetezeka ndi ma valve odziwikiratu, omwe amagwiritsidwa ntchito kwambiri mu ma boilers, zotengera zopondereza ndi mapaipi, kuti azitha kuwongolera kupanikizika kuti asapitirire mtengo womwe watchulidwa, ndipo amatenga gawo lofunikira pakuteteza chitetezo chamunthu ndi zida.
2. Kusiyana kwakukulu pakati pa valve yochepetsera kuthamanga ndi valve yotetezera:
1. Valavu yochepetsera mphamvu ndi chipangizo chomwe chimachepetsa sing'anga ndi kupanikizika kwakukulu kwapakati ndi kutsika kochepa.Kupanikizika ndi kutentha kuli mkati mwamtundu wina.
2. Ma valve otetezera ndi ma valve omwe amagwiritsidwa ntchito pofuna kuteteza ma boilers, zotengera zokakamiza ndi zipangizo zina kapena mapaipi kuti asawonongeke chifukwa cha kupanikizika kwambiri.Kupanikizika kukakwera pang'ono kuposa kukakamiza kwanthawi zonse, valavu yachitetezo imatseguka kuti ichepetse kuthamanga.Kuthamanga kukatsika pang'ono kusiyana ndi kuthamanga kwanthawi zonse, valavu yotetezera imatseka yokha, imasiya kutulutsa madzi ndikupitiriza kusindikiza.Mwachidule, valavu yotetezera ndiyo kuteteza kupanikizika kwa dongosolo kuti lisapitirire mtengo wina, ndipo makamaka amagwiritsidwa ntchito kuteteza dongosolo.Valavu yochepetsera mphamvu ndiyo kuchepetsa kupanikizika kwa dongosolo kuchokera ku kuthamanga kwapamwamba kupita ku mtengo wofunidwa, ndipo kutulutsa kwake kumakhala mkati mwamtundu, malinga ngati kuli mkati mwamtunduwu.
3. Valavu yotetezera ndi valavu yochepetsera kuthamanga ndi mitundu iwiri ya ma valve, omwe ndi ma valve apadera.Pakati pawo, valavu yachitetezo ndi ya chipangizo chotulutsa chitetezo , chomwe ndi valavu yapadera, yomwe imangogwira ntchito pamene kupanikizika kwa ntchito kumapitirira malire ovomerezeka, ndipo kumagwira ntchito yoteteza dongosolo.Valavu yochepetsera mphamvu ndi valavu yowonongeka yomwe imatha kusokoneza makina othamanga kwambiri kuti akwaniritse zofunikira za dongosolo la post-processing.Njira yake yogwirira ntchito ndi yopitilira.
