Valavu yachitetezo imayikidwa pazida, chidebe kapena mapaipi kuti ateteze kupsinjika.Pamene kupanikizika mu chidebe kapena payipi kupitirira mtengo wololeka, valavu idzatseguka kuti itulutse sing'anga;Kupanikizika kukatsikira pamtengo wotchulidwa, valavu idzatseka yokha.
Valavu yachitetezo imatha kugawidwa m'njira yolunjika komanso mtundu woyendetsedwa ndi woyendetsa molingana ndi mitundu yosiyanasiyana yoyendetsa.Mtundu wachindunji umayendetsedwa mwachindunji ndi kukakamizidwa kwa dongosolo pa cholowera cha valve.Panthawiyi, imagonjetsa kuthamanga kwapakati pansi pa valavu ya valve ndi katundu wamakina woperekedwa ndi kasupe kapena nyundo yolemera.Mtundu woyendetsa ndege umayendetsedwa ndi dongosolo, lomwe limagwiritsa ntchito njira yotulutsira kapena kugwiritsa ntchito mphamvu yotseka kutsegula kapena kutseka valavu yotetezera.
Ma valve otetezeka atha kugawidwa m'magulu awiri:
1. valavu yachitetezo chamtundu wa Spring
Gwiritsani ntchito mphamvu ya kasupe woponderezedwa kuti muyese kupanikizika kwa diski ya valve, kuti valavu yotetezera isindikizidwe.Valavu yotetezera ili ndi ubwino wokhudzika kwambiri, kusuntha ndi malo opanda malire oyika.Valavu yamtundu uwu imagwiritsidwa ntchito kwambiri.Choyipa chake ndi chakuti mphamvu yopondereza ya kasupe imasintha ndi mapindidwe a kasupe.Kutentha kukakhala kokwera, kasupe amakhala ndi kutsekereza kutentha komanso mavuto ochepetsa kutentha.
2. Lever ndi valavu yotetezera nyundo yolemera
Mphamvu ya nyundo yolemetsa imakulitsidwa ndi lever ndikuyikidwa pa diski ya valve.Ubwino wake ndikuti mphamvu yomwe imayikidwa pa diski ya valve imakhalabe yosasinthika pakutsegula ndi kutseka kwa valve.Choyipa chake ndikuti chimakhudzidwa ndi kugwedezeka ndipo sichichita bwino pakuyambiranso.Nthawi zambiri amagwiritsidwa ntchito pazida zokhazikika.
