     Mfundo yogwira ntchito yama Valve

Valavu ndi mtundu wa zida zowongolera kuti ayendetse madzimadzi, mfundo yake yogwirira ntchito ndikusintha kukula koyenda posintha malo oyambira pa mapaipi. Valavu imagwiritsidwa ntchito kwambiri mu hydraulic potumiza dongosolo ndikuchita mbali yofunika kwambiri. Zigawo zikuluzikulu za valavu yoyenda imaphatikizanso thupi la valavu, zinthu zoyambira (monga stal disc, etc.) ndi ochita ma electromact, etc.). Mitundu yosiyanasiyana ya mavuvu imasiyananso ndi kapangidwe kake, koma mfundo yawo yogwira ntchito ndiyofanana.
Malangizo a valavu yoyenda amatha kugawidwa njira ziwiri zokha: mawonekedwe a chinthu chowongolera ndi kusuntha kwa spool / disc.

Amagwira nawo valavu yothandiza
1, kukakamizidwa kosalekeza kuti: Pa njira yochulukitsa yopumira, pampu yochulukitsa imapereka nthawi zonse. Makina opanikizika akamachulukirachulukira, zomwe zimapangitsa kuti zitheke. ichi
Nkhota ya chitetezo ikatsegulidwa, yowonjezereka imabwezedwa ku tank kuti iwonetsetse kuti ziwopsezo za chitetezo, ndiye kuti, kupanikizika kwapampor, kumakhala kosinthika
Force mafunde amatsegulidwa).
2, Kukakamizidwa Kuwongolera: valavu imalumikizidwa pamilankhu yobwerera madera, valavu yothandizira imabweretsa zovuta zakumbuyo, ndipo kukhazikika kwa magawo osunthira kumawonjezeka.
3, Dongosolo lotsitsa ntchito: Doko lowongolera lamphamvu la valavu imalumikizidwa ndi valavu ya solenoid yokhala ndiulendo wocheperako. Pamene electromagnet imakhala ndi mphamvu, doko lakutali la valavu ya chitetezo ndi thanki yamafuta imalumikizidwa
Kulumikizidwa, nthawi ino kupukusa kwampukutu komwe kumatsitsa. Valavu ya chitetezo imagwiritsidwa ntchito ngati valavu yoteteza.
4, kutetezedwa kwa Chitetezo: Pomwe dongosolo likuchita bwino, valavu imatsekedwa. Kusefukira kokha pomwe katunduyo amapitilira malire otchulidwa (dongosolo la dongosolo limaposa makonda)
Valatilo itsegulidwa, ndikuteteza kuperewera kwa nthawi yayitali, kotero kuti kuthamanga kwa dongosolo sikuwonjezekanso (nthawi zambiri kumapanikizika kwa valavu yachitetezo ndi 10% - Kupanikizika Kwambiri Kwambiri)
Mphamvu).
