Ntchito yavalavu ya rabala：
Vavu ya rabara imagwiritsidwa ntchito kudzaza ndi kutulutsa mpweya mu tayala ndikusunga kuthamanga mu tayala. Vavu ya vavu ndi valavu yolowera mbali imodzi, galimoto yomwe imagwiritsidwa ntchito mu tayala si matayala a m'mbali, mu kapangidwe ka valavu ya vavu ndipo tayala limalekanitsidwa, valavu ya vavu imayikidwa mu rim kuti igwire ntchito yake.
Vavu mu tayala:
Popeza ndi gawo lokhalo la galimoto lomwe limakhudzana ndi nthaka, tayalali ndi lofunika kwambiri pa chitetezo cha galimotoyo. Kuti tayala, kuwonjezera pa korona, lamba, chingwe, ndi zigawo zingapo zomangira mkati mwake, kodi munaganizapo kuti pakamwa pa valavu kakang'ono nakonso kumachita gawo lofunika kwambiri pachitetezo choyendetsa galimoto?
Mphuno ya valavu ndi tayala zimalekanitsidwa:
Mphuno ya valavu ndi valavu yolowera mbali imodzi yomwe imagwiritsidwa ntchito kudzaza mpweya mu tayala ndikusunga mpweya mu tayala, mphuno ya valavu imalekanitsidwa ndi tayala, ndipo mphuno ya valavu imayikidwa pamphepete kuti igwire ntchito yake..
Kapangidwe kalikonse ka valavu kali ndi ntchito yakeyake:
Ngakhale ntchito ya valavu yolumikizira ndi yaying'ono, koma kapangidwe kake kangagawidwe m'magulu awiri: valavu, gasket, gasket, ndi fastening.mtedza wa zikwama, valavu yoyambira, chivundikiro cha valavu mbali izi, ndipo gawo lililonse lili ndi ntchito yake. Mwachitsanzo, kapangidwe ka valavu, thupi la valavu, ndiyo njira yokhayo yomwe mpweya umalowera mu tayala, imasunganso ndikuteteza valavu yoyambira: nati yomangirira, monga momwe dzinalo likusonyezera, imapanga nozzle ya valavu ndimkombero wachitsulootetezeka kwambiri; zipangizo ziwiri zosiyana za gasket zimagwiritsidwa ntchito limodzi ndi nati yomangira; Gasket ya rabara imagwiritsidwa ntchito kutseka mbali yamkati ya mkombero wa gudumu kuti mpweya usatuluke, ndipo chivundikiro cha valavu chomwe nthawi zambiri chimatayika chingapewe kusokoneza nozzle ya valavu, komanso nthawi yomweyo kutseka nozzle ya valavu. Ngakhale kuti pakati pa valavu pamatsimikizira kuti mpweya umalowa bwino mu tayala, imakhalanso ndi ntchito yoletsa mpweya kutuluka.
Makhalidwe osiyanasiyana a valavu yazinthu:
Pambuyo poyambitsa ma valavu osiyanasiyana, tidzakudziwitsani za makhalidwe a mavalavu osiyanasiyana. Ndi zoona, popeza zipangizo zosiyanasiyana zachitsulo zimagwiritsidwa ntchito m'mbali zonse za magalimoto, valavu si chinthu chimodzi cha rabara, zipangizo zachitsulo zakhala zikugwiritsidwa ntchito kwambiri mu valavu, ndipo pamsika wamakono, valavu ya rabara, chitsulo, aluminiyamu ndi mitundu itatu ya mavalavu azinthu ndizofala kwambiri. Mitundu itatu ya valavu ya rabara yazinthu ndi valavu yofala kwambiri, yotsika mtengo kotero kuti valavu ya rabara imasonkhanitsidwa kwambiri pamphepete yoyambirira ya gudumu.
Sinthani valavu ya rabara komanso tayala:
Chifukwa cha kukalamba kosapeŵeka kwa zipangizo za mphira, thupi la valavu lidzasweka pang'onopang'ono, kusintha kwa mawonekedwe, ndi kutayika kwa kusinthasintha. Ndipo galimoto ikayendetsa, valavu ya mphira idzagwedezekanso ndi kusintha kwa mphamvu ya centrifugal, zomwe zidzalimbikitsanso kukalamba kwa mphira. Nthawi zambiri, moyo wa valavu ya mphira ndi zaka 3-4, ndipo pafupifupi moyo wautumiki wa tayala, choncho tikulimbikitsidwa kusintha valavu ya mphira ndi tayala.
