Kudziwa zina za valve yonyowa ya alarm

Pakatikati pa dongosolo lozimitsa moto ndi mitundu yonse yavalavu ya alarms. Zotsatirazi ndizokhudzana ndivalavu yonyowa ya alarm.
1, mfundo yogwira ntchito
1) Pamene valavu yonyowa ya alamu ili mu quasi yogwira ntchito, chipinda chapamwamba ndi chipinda chapansi cha thupi la valve chimadzazidwa ndi madzi. Pansi pa kuthamanga kwa madzi ndi mphamvu yake yokoka, mphamvu yotsatizana ya madzi pa diski ya valve imatsikira pansi, zomwe zikutanthauza kuti kupanikizika kwa chipinda chapamwamba kumakhala kokwera pang'ono kuposa kupanikizika kwa chipinda chapansi, ndipo diski ya valve imatsekedwa. .
2) Pakakhala moto kapena dongosolo likatsegula chipangizo choyezera madzi kumapeto ndi valavu yoyesera madzi, kuthamanga kwa madzi kumbali ya dongosolo kumatsika mofulumira chifukwa cha kuphulika kapena kukhetsa kwa madzi.chowaza chotsekedwa. Pamene kupanikizika kwa chipinda chapansi kumakhala kwakukulu kuposa kupanikizika kwa chipinda chapamwamba, valavu ya valve imatsegulidwa ndi valavu ya alamu yomwe imatsegulidwa pamwamba pa kupanikizika kwa chipinda chapansi. Kuthamanga kwamadzi m'chipinda chotsika nthawi zambiri kumachokera ku tanki yamadzi amoto wapamwamba kwambiri komanso pampu yokhazikika.
3) Madzi amoto m'chipinda chotsika amapita ku retarder, kusinthana kwamphamvu ndi belu la hydraulic alarm kudzera papaipi ya alamu. Belu la hydraulic alarm limapereka alamu yomveka, ndipo kusintha kwamphamvu kumatumiza chizindikiro chamagetsi kuti ayambe pampu yamadzi amoto.
2, Mapangidwe a valavu ya alamu
Kumanga valavu yonyowa:
Thupi la valavu yonyowa, makina opangira magetsi, magetsi opangira madzi, compensator, valve yoyesa madzi (yomwe imatsekedwa), valve control valve (nthawi zambiri imatsegulidwa), valavu yoyesera alamu (yotsekedwa), fyuluta, retarder, kusintha kwamphamvu ndi belu la hydraulic alarm
Compensator: kuti athe kuthana ndi kutayikira kwakung'ono komanso kutayikira pang'ono kumbali ya kachitidwe kachitidwe ka tsiku ndi tsiku, thupi la vavu limapanga madzi owonjezera kuchokera m'chipinda cham'munsi kupita kuchipinda cham'mwamba kudzera pa compensator kuti apititse patsogolo kupanikizika. zipinda zapamwamba ndi zapansi.
Valavu yoyesera ma alarm: yesani ntchito ya valavu ya alamu ndi belu la alamu.
Retarder: payipi yolowera ndi alamu imalumikizidwa wina ndi mzake, ndipo chotulukacho chimalumikizidwa ndi chosinthira chokakamiza. Chosefera chidzayikidwa kutsogolo kwa retarder. Kutayikira kwa payipi yogawa madzi, chotchinga cha valve chidzatsegulidwa pang'ono, ndipo madzi amalowa mupaipi ya alamu. Chifukwa madzi akuyenda pang'ono, amatha kutulutsidwa kuchokera kumtunda wa retarder, kotero sichidzalowa mu belu la hydraulic alarm ndi kukakamiza kusinthana kuti musapewe alamu onyenga.
Pressure switch: chosinthira chopondereza ndi sensor yokakamiza, yomwe imagwiritsidwa ntchito kutembenuza chizindikiro chamagetsi kukhala chizindikiro chamagetsi.
Belu la hydraulic alarm: motsogozedwa ndi mphamvu ya hydraulic, madzi amalowa mu hydraulic alarm belu ndikupanga jeti yachangu. Gudumu lamadzi limayendetsa nyundo ya belu kuti izungulire mwachangu, ndipo chivundikiro cha belu chidzalira alamu.
