Kachitidwe

valavu yotetezera yomwe imagwiritsidwa ntchito kuwongolera kapena kuchepetsa kupanikizika mu dongosolo; Kupanikizika kungathenso kumangirira ndikuyambitsa kusokonezeka, chida kapena kulephera kwa zida, kapena moto. Kupanikizika kumatsitsimutsidwa mwa kulola kuti madzi opanikizika atuluke kuchokera ku gawo lothandizira kunja kwa dongosolo. Valve yothandizira imapangidwa kapena kukhazikitsidwa kuti itseguke pakukakamizidwa kokonzedweratu kuti ateteze zotengera zokakamiza ndi zida zina kuti zisakumane ndi zovuta zomwe zimapitilira malire awo. Kupanikizika kokhazikika kukadutsa, valve yothandizira imakhala "njira yochepetsera kukana" pamene valve imakakamizidwa kutsegulidwa ndipo gawo lina lamadzimadzi limapatutsidwa kudzera mu njira yothandizira. Madzi opatutsidwa (zamadzimadzi, gasi kapena osakaniza amadzimadzi) nthawi zambiri amayendetsedwa kudzera mu mapaipi omwe amadziwika kuti mutu wamoto kapena mutu wampumulo kupita kupakati, komwe kumayaka gasi komwe nthawi zambiri amawotchedwa ndipo mipweya yoyaka yomwe imatuluka imatulutsidwa kumlengalenga. . Pamene madziwa amapatutsidwa, mphamvu ya mkati mwa chombocho imasiya kukwera. Ikafika kukakamiza kwa valve, valve imatseka. Kuphulika kumatchulidwa ngati chiwerengero cha kupanikizika kokhazikika ndipo kumatanthawuza kuchuluka kwa kupanikizika kumafunika kutsika valavu isanayambe. Kuwombera kumatha kusiyanasiyana kuchokera ku 2-20%, ndipo ma valve ena amakhala ndi kuphulika kosinthika.

Ntchito:

Ntchito zida ndi mapaipi ndi mafuta, mpweya, madzi ndi TV zina ndi kutentha ntchito ≤300 ℃.
