Mtundu wa valve yothandizira

Malinga ndi mawonekedwe osiyanasiyana, valavu yothandizira ikhoza kugawidwa m'magulu awiri: mtundu wochita molunjika ndi mtundu wotsogolera. Direct acting relief valve ndi valavu yopumula momwe kuthamanga kwa hydraulic kwa mzere waukulu wamafuta omwe akugwira pa spool kumayenderana mwachindunji ndi kukakamiza kowongolera mphamvu yamasika. Malinga ndi mawonekedwe amitundu yosiyanasiyana ya doko la valve ndi malo oyezera kuthamanga, zida zitatu zoyambirira zimapangidwa. Ziribe kanthu mtundu wamtundu wanji, valavu yothandizira mwachindunji imapangidwa ndi magawo atatu: kukakamiza kowongolera kasupe ndi chowongolera chowongolera, doko kusefukira ndi malo oyezera kuthamanga. Kuyerekeza pakati pa valavu yothandizira mwachindunji ndi valavu yotsogolera yothandizira: valavu yothandizira molunjika: mawonekedwe ophweka, okhudzidwa kwambiri, koma kupanikizika kumakhudzidwa kwambiri ndi kusintha kwa kusefukira kwa madzi, kupatukana 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 kake Kuthamanga, komwe nthawi zambiri kumagwiritsidwa ntchito ngati valavu yotetezera kapena nthawi zina pomwe kulondola kwa malamulo sikuli kwakukulu.

Valavu yoyendetsa ndege: Kasupe wamkulu wa vavu amagwiritsidwa ntchito makamaka kuthana ndi kukangana kwapakati pa valve, ndipo kuuma kwa kasupe kumakhala kochepa. Pamene kusintha kwa kusefukira kumayambitsa kusintha kwakukulu kwa valve kasupe, kusintha kwa mphamvu ya masika kumakhala kochepa, kotero kusintha kwa valve yolowera kumakhala kochepa. Kuwongolera kwamagetsi apamwamba kwambiri, komwe kumagwiritsidwa ntchito kwambiri pakuthamanga kwambiri, dongosolo lalikulu loyenda. Chiwombankhanga cha valavu chothandizira chimayendetsedwa ndi kukangana panthawi yosuntha, ndipo chiwongolero cha kukangana pa nthawi yotsegulira ndi kutseka kwa valve ndi yosiyana, kotero kuti mawonekedwe a valve yothandizira amasiyana pamene atsegulidwa. ndipo ikatsekedwa.
