Momwe ma valve owongolera, ma valve a globe, ma valve a zipata ndi ma cheke amagwirira ntchito

Valve yowongolera, yomwe imatchedwanso control valve, imagwiritsidwa ntchito poyang'anira kukula kwa madzi.Pamene gawo loyang'anira la valve limalandira chizindikiro chowongolera, tsinde la valve limangoyang'anira kutsegula ndi kutseka kwa valve malinga ndi chizindikiro, motero kuwongolera kuthamanga kwa madzi ndi kuthamanga;Nthawi zambiri amagwiritsidwa ntchito potenthetsa, gasi, petrochemical ndi mapaipi ena.

Vavu yoyimitsa, yomwe imadziwikanso kuti valavu yoyimitsa, imatha kutseka chitseko cha mpando wa valve pogwiritsira ntchito kukakamiza pozungulira tsinde la valve, motero kuteteza kutuluka kwa madzi;ma valve oyimitsa amagwiritsidwa ntchito kwambiri mu gasi, gasi wamadzimadzi, sulfuric acid ndi mpweya wina wowononga ndi mapaipi amadzimadzi.

Valve ya gateali ngati chipata.Pozungulira tsinde la valve, mbale ya pachipata imayendetsedwa kuti isunthe molunjika mmwamba ndi pansi kuti iwononge madzi.Mphete zosindikizira mbali zonse za mbale ya pachipata zimatha kusindikiza kwathunthu gawo lonselo.Valve yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, ndipo singagwiritsidwe ntchito kuwongolera kuyenda.Ma valve a zipata amagwiritsidwa ntchito kwambiri ngati zida zolowera m'madzi apampopi, zimbudzi, zombo ndi mapaipi ena.
 

Valve yoyang'ana swingamadalira kuthamanga kwa madzimadzi kuti atsegule chivundikiro cha valve.Pamene kuthamanga kwa madzi mu valavu ndi mapaipi otulutsirako kuli koyenera, chophimba cha valve chikhoza kutseka ndi mphamvu yake yokoka kuti madzi asadutse.Ntchito yake yayikulu ndikuletsa madzimadzi kuti asabwererenso.Flow, ndi ya gulu lodziwikiratu la valve;makamaka ntchito mafuta, mankhwala, mankhwala ndi mapaipi ena.
