     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.

Choyamba, madzi akamadutsa m'thupi la valavu yoyendayenda, imakumana ndi chikonzero chowongolera. Zinthu zomwe zimayendetsedwa ndi malo ena mu thupi la valavu, ndipo malo oyenda amadzimadzi amatha kusinthidwa ndikusintha malo awo. Mwanjira imeneyi, kuyenda kwamadzi kumatha kuwongoleredwa. Makonda oyambira ali ndi spool ndi disc.

Kachiwiri, valavu yoyenda ilinso ndi spool kapena kayendedwe kake, yomwe gulu lawo limasintha madziwo kudutsa thupi la valavu. Mwachitsanzo, ma electromaagnet atayambitsidwa, spool imasunthidwa kapena pansi ndi mphamvu yamagetsi. Izi zimasintha mawonekedwe a chinthu chowongolera, chomwe chimathamangitsa madzi. Momwemonso, poyendetsa galimoto ya Hydraulic ikayendetsa valavu kuti ichoke, isinthanso malowa amadzimadzi, potero kutumiza kuchuluka kwake.
