Vavu yopumulira ya Hydraulic RV-10 yokhala ndi hydraulic valve block base pipeline pressure relief valve yolumikizidwa ndi pulagi yolunjika yogwira ntchito

Tanthauzo la "vavu" ndi chipangizo chomwe chimagwiritsidwa ntchito kuwongolera komwe akupita, kuthamanga ndi kutuluka kwamadzimadzi mumadzimadzi. Mavavu ndi zida zomwe zimapanga sing'anga (zamadzimadzi, gasi, ufa) mu mapaipi ndi zida kuyenda kapena kuyimitsa, ndipo zimatha kuwongolera kuyenda kwake. Valve ndi gawo lowongolera mumayendedwe oyendetsa mapaipi amadzimadzi, omwe amagwiritsidwa ntchito kusintha gawo la gawo la ndimeyi ndi kayendedwe ka sing'anga, ndipo ali ndi ntchito zosokoneza, kudula, kusintha, kugwetsa, kusabwerera. , kupatukana kapena kusefukira mpumulo wa kupsyinjika. Mavavu omwe amagwiritsidwa ntchito powongolera madzimadzi amachokera ku ma valve osavuta odulira kupita kumitundu yonse ya mavavu omwe amagwiritsidwa ntchito m'makina ovuta kwambiri owongolera okha, ndipo ma diameter awo amachokera ku mavavu ang'onoang'ono kupita kumapaipi a mafakitale okhala ndi mainchesi 10m. Mavavu amatha kugwiritsidwa ntchito kuwongolera kutuluka kwamitundu yosiyanasiyana yamadzimadzi, monga madzi, nthunzi, mafuta, gasi, matope, zowononga media, zitsulo zamadzimadzi ndi madzimadzi a radioactive. Kuthamanga kwa ma valve kumagwira ntchito kuchokera ku 1.3х10MPa kufika ku 1000MPa, ndipo kutentha kwa ntchito kumatha kuchoka pa kutentha kwambiri -269 ℃ mpaka kutentha kwa 1430 ℃. Valavu imatha kuyendetsedwa ndi njira zosiyanasiyana zotumizira, monga manual, magetsi, hydraulic, pneumatic, worm gear, electromagnetic, electromagnetic-hydraulic, magetsi-hydraulic, pneumatic-hydraulic, spur gear ndi bevel gear drive. Pansi pa kukakamizidwa, kutentha kapena mitundu ina ya zomverera, imatha kuchita molingana ndi zomwe zidakonzedweratu, kapena kungotsegula kapena kutseka osadalira ma siginecha. Valavu imadalira kuyendetsa galimoto kapena makina odzipangira okha kuti magawo otsegulira ndi otseka asunthire mmwamba ndi pansi, slide, swing kapena kuzungulira, motero amasintha kukula kwa malo ake othamanga kuti azindikire ntchito yake yolamulira.
