Makina ndi hydraulic plug-posonkhanitsa valavu FD50-5

Valve valve, omwe amadziwikanso kuti valavu yokhomerera, kutolera valavu ya valavu, valavu imodzi, valani yonyamula mbali imodzi ndi mogwirizana ndi valavu yosinthira mavesi a Hydraulic. Valavu yolumikizana imagwiritsidwa ntchito makamaka ndi silinda-cylinder yolumikizira hydraulic. Nthawi zambiri, pali njira zambiri zoyenera kuzindikira zosunthika, koma valavu yokhotakhota ndi yosoka, imakhala yochepa kwambiri komanso kudalirika kofunikira, kotero kuti kudalirika kokwanira mu hydraulic dongosolo. Kuphatikizika kwa phokoso komanso kusonkhanitsa valavu ndiko kudulira. Cylinders awiri kapena kupitilira apo amakhala ndi katundu wosiyanasiyana, wosuntha komanso wotola amatha kutsimikiziranso mayendedwe ake.

Kugwira nchito

Ntchito ya valavu yopanda tanthauzo ndikupereka zotulukazo (zofanana) kwa ochita malonda awiri kapena kupitilirapo kuchokera kuzomwezi (zowoneka bwino) kwa ochitapo kanthu, kuti athe kuthamanga kwa ochitapo kanthu.

Ntchito ya valavu yosonkhanitsa ndikutola nkhuni zofananira kapena zongobwerera kuchokera kwa ochitapo kanthu awiri, kuti azindikire kuthamanga kapena kuyanjana pakati pawo. Kupukusa ndi kusonkhanitsa valavu kumakhala ndi mavavu opukutira ndi kutolera.

Chithunzi chojambulidwa ndi zinthu zofananira za valavu yofanana amatha kuonedwa ngati kuphatikiza kwa zinthu ziwiri, kumachepetsa mavesi oyambira. Valavu imatengera "njira yosinthira", ndipo imagwiritsa ntchito ma ordic awiri okhazikika 1 ndi 2 ndi malo omwewo ngati ma tyspoes ophatikizika kuti asinthe q1 ndi Δ p2 motsatana. Kusiyana kwa kupanikizika Δ p1 ndi Δ p2 kumayimira katundu ziwirizi ngati ma q1 ndi Q2 amathandizidwanso ku Varve Core 6 nthawi yomweyo, ndipo kupsa mtima kumatha kusintha kukula kwa Q1 ndi Q2 kuti ipange kukhala ofanana.
