   Udindo wake wa ma hydraulic valves

Valavu ya hydraulic imagwiritsidwa ntchito kuwongolera kayendedwe ka mafuta mu hydraulic system kapena kusintha kuthamanga kwake ndikuyenda, kotero imatha kugawidwa kukhala ma valve owongolera, ma valve opanikizika ndi ma valve otaya.
Magulu atatu otakata. Valve yokhala ndi mawonekedwe omwewo imatha kukhala ndi ntchito zosiyanasiyana chifukwa cha machitidwe osiyanasiyana. Valve yothamanga ndi valve yothamanga imagwiritsa ntchito gawo loyenda
Kuchita kwa throttling kumayang'anira kuthamanga ndi kuyenda kwa dongosolo, pamene valavu yowongolera imayendetsa kayendedwe ka mafuta posintha njira yotuluka. Ndiko kunena, komabe
Pali mitundu yosiyanasiyana ya ma hydraulic valves, ndipo amasungabe mfundo zina zofanana. Mwachitsanzo:
(1) Mwadongosolo, ma valve onse amapangidwa ndi thupi la valve, spool (valvu ya rotary kapena slide valve), ndi zinthu ndi zigawo (monga akasupe ndi maginito amagetsi) zomwe zimayendetsa ntchito ya spool.
(2) Pankhani ya mfundo yogwirira ntchito, mgwirizano pakati pa kukula kwa ma valve onse otsegulira, kusiyana kwapakati pakati pa kulowetsa ndi kutuluka kwa valve ndi kutuluka kwa valve kumagwirizana ndi kutuluka kwa orifice.
Magawo okhawo owongolera ma valve osiyanasiyana ndi osiyana.

Valve ya Hydraulic ndi gawo lodziwikiratu lomwe limayendetsedwa ndi mafuta oponderezedwa, limayendetsedwa ndi mafuta othamanga, omwe nthawi zambiri amaphatikizidwa ndi ma electromagnetic pressure valve, amatha kugwiritsidwa ntchito kuwongolera kutali kwamafuta a hydropower station, gasi, mapaipi amadzi. Amagwiritsidwa ntchito ngati clamping, control, lubrication ndi zina zozungulira mafuta. Pali mtundu wa zochita zachindunji ndi mtundu wa upainiya, wogwiritsa ntchito zambiri. Udindo wa hydraulic valve umagwiritsidwa ntchito makamaka kuchepetsa ndi kukhazikika kwa mphamvu ya mafuta a nthambi m'dongosolo, ndipo nthawi zambiri amagwiritsidwa ntchito popanga, kulamulira, kudzoza mafuta ndi maulendo ena amafuta. Pali mwachindunji kusuntha mtundu, kutsogolera mtundu ndi superposition mtundu. Chigawo chomwe chimagwiritsidwa ntchito potumiza ma hydraulic kuwongolera kuthamanga, kuyenda, ndi komwe zakumwa. Valve yowongolera kuthamanga imatchedwa valve control valve, valve control valve imatchedwa valve control valve, ndipo kuwongolera, kutsika ndi kuwongolera kumatchedwa valavu yowongolera. Gulu la ma hydraulic valves: gulu ndi ntchito: valavu yothamanga ( valve yothamanga, valavu yoyendetsa liwiro, valavu ya diverter, valavu yosonkhanitsa, valavu yosonkhanitsa), valavu yamagetsi (valavu yothandizira, valavu yochepetsera, valavu yotsatizana, valavu yotsitsa), valavu yotsogolera ( valavu yamagetsi yamagetsi, valavu yosinthira pamanja, valavu yoyang'ana, valavu yoyang'anira ma hydraulic control)
